Chapter 534 Professor Lu leads the world againRobot technology is a systematic project.
Including materials technology, computer technology, machining technology, electrical control technology and many other technologies.
At present, the bottleneck restricting the development of my country's robot technology is mainly the reducer, the servo motor, and the control system.
Well, remove these three pieces, and there's nothing left.
In the next period of time, Lu Li focused on the research and development of reducer technology.
Reducers are the key to robotics. For a robot to perform an action, it must precisely control the action to ensure that there is no slightest error.
Here, the reducer is the key.
If the reducer fails to close, even if the data set by the control system is accurate, the corresponding action requirements cannot be achieved.
From a certain point of view, the reducer of a robot is actually very similar to the gearbox of a car, and it is the same principle.
But...the technical requirements are the exact difference between Above the Heavens and Under the Earth.
The research and development of domestic robot reducers is difficult because the reducer itself has extremely high precision requirements, and the machining accuracy of parts and components has reached the micron level.
This precision is unimaginable, only one unit higher than the nanometer level of silicon-based chip lithography.
To achieve such processing accuracy, it involves processing equipment, operator skills, technological process arrangements, environmental conditions and so on.
For example, when performing such precision machining, if you cough, it may affect the machining accuracy.
apart from this , the design of the reducer is also the key. In this regard, the domestic lack of advanced design in this area, resulting in the performance of the reducer can not reach the foreign level.
For Lu Li, design is not an issue at all.
The robot technology in Refuge Technology, of course, includes the design of various high-precision reducers, just copy it.
But... the design alone is not enough, the machining accuracy must also be solved.
The reducer of the shelter is manufactured using laser processing technology for precision machining. This technology... can be used.
Before controllable nuclear fusion was developed, the use of laser processing technology would lead to huge energy consumption and high production costs, but... this is a question of whether or not to solve it.
On some key equipment, whether there is or not is the most important, and the energy consumption and cost are completely negligible.
First step, come up with high-precision laser processing technology!
This technology belongs to the nature of the tool and can be widely used in the processing of various high-precision parts, not only for the processing of reducers.
Such as aerospace, such as aviation, such as missiles, such as nuclear submarines, such as aircraft carriers...
An inertial gyroscope, like the use of high-precision laser processing technology, can improve the accuracy of the gyroscope an order of magnitude. This can greatly improve the guidance accuracy in aerospace and missile technology.
The high-precision laser processing technology of the shelter can be directly taken out.
Lu Li sits at his desk and starts to write the material list, equipment list, technical theoretical documents, and plan the experimental procedure.
"Old Tian, I want these equipment and materials!"
Lu Li called Assistant Tian over and handed him a list.
This list contains the processing equipment and materials needed for Lu Li. Lu Li plans to make a prototype of a high-precision laser processing equipment in the laboratory.
Assistant Tian hurried into the office and took the list from Lu Li.
"Professor Lu, I will report to the top immediately. What you want will be delivered in the shortest time."
Seeing this long list, Assistant Tian Heart excited again. Obviously, Professor Lu is about to come up with another high-tech new technology.
Why am I not surprised at all?
Laughed, Assistant Tian ran out of the office in a hurry, reported the situation to the top, and submitted Lu Li's list.
"Professor Lu is going to do research again?"
The head above received the list and saw a string of equipment and materials on the list, and a smile appeared on his face .
Equipment? Material? It's not a problem!
Professor Lu will give whatever he wants, no matter how much he spends, he must prepare it in the shortest possible time.
Today's Lu Li is already a national treasure-level scientist.
Which of the technologies that Lu Li has come up with before is not leading the world? How important is the strategic value of the successful research of these technologies? How much technological breakthrough and technological progress has it brought to the country?
A day later, a heavy-duty rotorcraft slowly landed at the Baoshan base. All kinds of equipment and materials needed by Lu Li were continuously sent to the underground laboratory.
This heavy-duty rotorcraft is the Iron Bird rotorcraft developed by Lu Li before.
After a period of technical verification, the Iron Bird rotorcraft has begun mass production and has begun to be equipped on a large scale.
Lu Li didn't care about that at all.
When the equipment was installed and the materials were sent to the lab, Lu Li started working.
Lu Li spent the next week working in the lab. With the help of high-precision equipment such as 3D printers and high-precision CNC machining centers, Lu Li slowly assembled the parts of a high-precision laser processing equipment.
The overall structure material is titanium-chromium-tantalum carbide carbide developed by Lu Li himself. The laser emission port is made of tantalum carbide high temperature resistant material.
Gene chip is used for the control chip, graphene is used for the wire, and carbon nanotube composite material is used for the transmission mechanism.
Various parts were assembled one by one, and a high-precision laser processing equipment was officially completed.
This is a prototype machine, naturally not that particular, not even a shell, it looks a bit rough, but... highly technical.
Turn on the power and start the equipment. Lu Li put the blueprint of the reducer he designed into the gene chip computer of the laser processing center, installed the material on the fixture, and reached out and pressed the start button.
Then...the machine runs automatically, the laser hits the material, and the cutting process begins.
The advantage of laser cutting is that it does not need to change the tool at all, and it can cut to the end from roughing to finishing.
After half an hour, the core components of the reducer, the precision components of the pendulum planetary gear, have been processed.
Remove the parts, and Lu Li uses high-precision measuring equipment to test the accuracy of the parts.
The test results show that the accuracy of the parts fully meets the requirements, the surface roughness, dimensional tolerance, fit tolerance, coaxiality...etc. The error is not more than 1 micron at most.
This is already the highest precision in machining technology.
The high-precision laser processing equipment fully meets the design requirements and has been successfully researched.
The only downside is...this thing consumes a lot of power.
Before the advent of controlled nuclear fusion, the use of laser processing technology would lead to relatively high production costs.
However...for this kind of highest high-precision machining technology, for a country, it only needs to solve the problems, and does not care about the cost at all.
Who cares about the cost of this strategic high-precision machining technology?
Without this technology, the cost of ultra-high-precision machining would be more than a hundred times higher.
Successful research, or "successful plagiarism", Lu Li turned back to the office and started writing technical materials.
Lu Li wrote down the theoretical data, design scheme, production process, all experimental process and experimental data of high-precision laser processing technology in detail.
After finishing this, Lu Li began to summarize Tian's assistant again.
"Old Tian, come here to receive the goods!"
Lu Li turned his head and shouted, and Assistant Tian appeared quickly.
"Professor Lu, your research...is successful again?"
Assistant Tian laughed, well, why do I say "again"?
"I developed a high-precision laser processing technology."
Lu Li took out the technical materials and handed them to Assistant Tian, "There is also a speed reducer attached to it. The design blueprint and processing technology. You hand it in!"
"Yes!"
Assistant Tian quickly took the lead.
Although it is unclear how important this technology is, there is nothing that Professor Lu has researched that is not high-tech.
Soon, this technical information was presented to the military chief.
"High-precision laser processing technology? And reducer design?"
The military chief is not specialized in technology, and he could not understand Lu Li's research for a while How valuable is the data.
It doesn't matter if the boss doesn't understand it, just the people below.
The military chief immediately forwarded the technical data to the General Armament Department for technical experts to conduct technical demonstrations.
“High-precision machining technology with an error of no more than one micron?”
Technical experts from the General Armament Department, after seeing this information, stared wide-eyed one by one.
This is the highest high-precision machining technology. This is a high-tech of great strategic significance.
In the defense industry, as well as the aerospace industry, the pursuit of precision is almost endless.
High precision means high performance and reliability.
This technology is of great strategic significance in the processing of parts for space stations, satellites, launch vehicles, and even strategic weapons.
The simplest point, how much positioning and navigation accuracy can an ultra-high-precision gyroscope bring?
Dongfeng Express's drop-point accuracy can also be improved by an order of magnitude, with an error of no more than ten meters. For a strategic weapon, this accuracy is simply appalling, a total excess.
"Professor Lu is too strong!"
An expert couldn't help but sigh, "Professor Lu also has such high attainments in precision machining technology. What else is there to do with him? Will it be possible?"
"Huh? Look! Behind this document, there is a design drawing and processing technology of the reducer."
An expert next to him saw the document The technical information of the reducer listed at the end had a dull look on his face, "Everyone, I have a guess. Could it be that Professor Lu developed the high-precision machining technology for the purpose of machining the reducer?"
"I'm afraid That's true."
Another expert looked helpless, "For example, because I wanted to eat eggs, I created a hen that lays golden eggs. The world of genius is really unimaginable."
"Compared with this ultra-high-precision machining technology, the reducer is nothing! This is just a small application direction of high-precision machining technology."
"I'm afraid even Professor Lu himself doesn't know how strategically important this high-precision processing technology is."
"If Professor Lu thinks that charging the mobile phone is too troublesome, will the controllable nuclear fusion technology be used? Get it out?"
"Haha! Maybe it's possible!"
This ultra-high-precision laser processing technology was quickly verified.
The Ministry of Aerospace Industry immediately took this technology and produced a batch of high-precision laser processing equipment according to the technical data, which fully confirmed the reliability of this technology.
For a while, various high-tech departments were rejoicing.
This technology is needed for the production of satellites, for the production of launch vehicles, for the production of aircraft, for the production of missiles, for the production of nuclear submarines, and for the production of aircraft carriers. Want this kind of technology...
Various processing equipment developed based on high-precision laser processing technology has sprung up like mushrooms after a rain.
Of course, Lu Li's reducer design scheme has also been widely used.
Aren't the current high-precision machining equipment all automated equipment? A high-performance reducer is also very important.
It's just... Compared with the high-precision laser processing technology itself, the technology of the reducer is just a component technology.
The domestic high-precision machining equipment has begun to be fully updated.
Because this high-precision machining technology is already available in China, the negotiations with the Teutonic countries to introduce technology have completely stopped.
Originally, the Teutonic Kingdom also put on an aloof and remote attitude, ready to slash the knife fiercely, lion's big mouth, and shouted the astronomical price.
More importantly, the technology given by the Teutonic countries is still backward technology, and the machining accuracy can only reach 30 microns.
Now...sorry, we don't!
The Teutonic nation was stunned to learn that the Chinese nation no longer wanted the 30-micron precision machining technology. what's going on? Why do rabbits suddenly stop using this technology?
30 micron precision machining technology, although we have eliminated it, but...you don't have it?
You're sharpening your knives, why don't you come and get knives?
At the same time, on the international black market, buyers looking for high-precision machining technology all over the place disappeared for a while.
Many people who are about to use the elimination technology to slaughter the rabbit with a knife, are horrified and completely confused.
"News from this station: Professor Lu Li, a famous scientist in my country, has developed a new generation of high-precision machining technology, the machining accuracy has reached the micron level, and the error does not exceed one micron."
" The successful development of this technology marks that my country has reached the world's leading level in high-precision machining technology!"
As soon as the news came out, the domestic response was mediocre.
Professor Lu leads the world again. Well, this is the basic operation.
There was an uproar abroad.
Fuck! This kind of Hua Family's high-precision machining technology actually achieves an error of no more than one micron?
We're still struggling in the ten-micron range, why are you at one?
And... is that Professor Lu again?
A genetic scientist, what kind of high-precision machining technology do you study? It's not business, you know what?
