Chapter 537

Robot technology is a system engineering.

Including material technology, computer technology, machining technology, electrical control technology and other aspects of technology.

At present, the bottleneck restricting the development of robot technology in our country is mainly reducer, servo motor and control system.

Well, take out these three big pieces, and there's nothing left.

In the next period of time, Luli focused on the research and development of reducer technology.

Reducer is the key of robot technology. If a robot wants to perform a certain action, it must accurately control the action to ensure that there is no slightest error.

Here, the reducer is the key.

If the reducer does not pass, even if the data set by the control system is more accurate, it can not achieve the corresponding action requirements.

From a certain point of view, the reducer of a robot is very similar to the gearbox of a car. They all share the same principle.

But However, the technical requirements are completely different between the sky and the earth.

There are many difficulties in the research and development of robot reducer in China. The reason is that the precision of reducer itself is very high, and the machining precision of parts reaches micron level.

This precision is unimaginable, only one unit higher than the nanometer level of silicon-based chip lithography.

To achieve such machining accuracy, it involves processing equipment, operator technology, process arrangement, environmental conditions and so on.

For example, during this kind of precision machining, if you cough, the machining accuracy may be affected.

In addition, the design of reducer is also the key. In this respect, the lack of domestic advanced design in this area leads to the reducer performance can not reach the level of foreign countries.

For Luli, design is not a problem at all.

The robot technology in shelter technology, of course, includes all kinds of design schemes of high-precision reducer, as long as you copy them.

But Design alone is not enough, but the problem of machining accuracy must be solved.

The reducer manufacturing and precision machining of the refuge use laser processing technology. This technology You can use it.

Before the controllable nuclear fusion, using laser processing technology will lead to huge energy consumption and high production cost, but This is to solve the problem of whether there is any.

In some key equipment, whether there is one is the most important, and the energy consumption and cost can be completely ignored.

The first step is to take out high-precision laser processing technology!

This technology belongs to the nature of the tool technology, can be in a variety of high-precision parts processing, has been widely used, not only for processing reducer.

Such as aerospace, such as aviation, such as missiles, such as nuclear submarines, such as aircraft carriers

An inertial gyroscope, like using high-precision laser processing technology, can improve the accuracy of the gyroscope by 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.

Sitting in front of his desk, Lu Li began to compile material list, equipment list, technical and theoretical documents, and planned experimental steps.

"Lao Tian, I want these equipment and materials!"

Lu Li called assistant Tian over and gave him a list.

This list contains the processing equipment and materials required for land departure. Lu Li is going to make a prototype of high-precision laser processing equipment in his laboratory.

Assistant Tian hurried into the office and took the list from Lu Li.

"Professor Lu, I'll report to them immediately. What you want will be delivered in the shortest possible time. "

Seeing this long list, assistant Tian was excited again. Obviously, Professor Lu is going to come up with a new and sophisticated technology.

Why am I not surprised at all?

Tian assistant smile, rushed out of the office, report to the above, submit the list of Luli.

"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, with a smile on his face.

Equipment? Material Science? It's not a problem!

Professor Lu will give whatever he wants. No matter how much money he spends, he must be fully prepared in the shortest time.

Now Lu Li is a national treasure scientist.

Which of the technologies that Luli used to bring out is not ahead of the rest of the world? How important is the strategic value of the successful research of these technologies? How much technological breakthrough and progress has it brought to the country?

A day later, a heavy rotor transport plane slowly landed at Baoshan base. All kinds of equipment and materials needed by Luli are continuously sent to the underground laboratory.

This heavy rotorcraft is the iron bird rotorcraft developed before landing.

After a period of technical verification, the iron bird rotorcraft has begun mass production and large-scale equipment.

Lu Li doesn't care about this at all.When the equipment was installed and the materials were sent to the laboratory, Luli began to work.

For the next week, Lu Li had been working in the laboratory. In the 3D printer, high-precision CNC machining center and other high-precision equipment, Luli slowly assembled the parts of a high-precision laser processing equipment.

The overall structure material is titanium chromium tantalum carbide cemented carbide developed by Luli. The laser emitter uses tantalum carbide high temperature resistant material.

The control chip is gene chip, the wire is graphene, and the transmission mechanism is carbon nanotube composite.

Various parts are assembled one by one, and a high-precision laser processing equipment is officially completed.

This is a prototype. Naturally, it's not so particular. It doesn't even have a shell. It looks a little rough, but The technology content is very high.

After connecting the power supply and starting the equipment, Luli input the gear reducer drawing designed by himself into the gene chip computer of the laser processing center, installed the material on the fixture, reached out and pressed the start key.

And then The machine runs automatically, the laser hits the material and starts cutting.

The advantage of laser cutting is that it doesn't need to change the tool at all. From rough machining to finish machining, it can cut to the end.

Half an hour later, the core part of the reducer, the precision component of the pendulum planetary gear, has been processed.

Take down the parts and use 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, surface roughness, dimensional tolerance, fit tolerance, coaxiality And so on, the maximum error is not more than 1 micron.

This is the highest precision in machining technology.

High precision laser processing equipment, fully meet the design requirements, has been successfully studied.

The only drawback is This thing consumes a lot of electricity.

Before the appearance of controllable nuclear fusion, the use of laser processing technology will lead to higher production costs.

However This kind of top-level high-precision processing technology, for a country, only needs to solve the problem of whether there is or not, and does not care about the cost at all.

Who cares about the cost of this strategic high precision machining technology?

Without this technology, to achieve ultra-high precision processing, the cost is more than 100 times higher.

After successful research, or "successful plagiarism", Lu Li turned back to his office and began to write technical materials.

Lu Li has written down the theoretical data, design scheme, production process, all experimental processes and experimental data of high-precision laser processing technology in detail.

After that, Lu Li began to call assistant Tian.

"Lao Tian, come to receive the goods!"

Lu Li turned his head and yelled. Assistant Tian came out quickly.

"Professor Lu, your research Again? "

Assistant Tian smiles. Well, why should I say "again"?

"I have developed a high-precision laser processing technology."

Lu Li took out the technical information and handed it to assistant Tian, "there is also a design drawing and processing technology of the reducer. Hand it in

"Yes

Assistant Tian quickly took orders.

Although it is not clear how important this technology is, none of the things that Professor Lu has developed are not high-tech.

Soon, the technical information was submitted to the head of the military.

"High precision laser processing technology? And reducer design? "

The military chief is not specialized in technology. For a moment, he can't figure out the value of this research material.

It doesn't matter if the chief doesn't understand, just the people below.

The military chief immediately forwarded the technical information to the general equipment department for technical experts to conduct technical demonstration.

"High precision machining technology with error less than one micron?"

The technical experts of the General Armament Department, after seeing this information, opened their eyes one by one.

This is the highest precision machining technology. This is a high and new technology of great strategic significance.

In the national defense industry, as well as the aerospace industry, the pursuit of precision is almost endless.

High precision represents high performance and high reliability.

This technology is of great strategic significance in the processing of spare parts for space stations, satellites, launch vehicles and even strategic weapons.

The simplest point is, how much positioning and navigation accuracy can an ultra-high precision gyroscope bring?

The accuracy of Dongfeng Express's landing point can also be improved by an order of magnitude, and the error can not exceed 10 meters. For strategic weapons, this precision is simply appalling and totally excessive.

"Professor Lu is too strong!"

An expert could not help sighing, "Professor Lu has such high attainments in precision machining technology. Is there anything else he won't do? "

"Why? Look! At the back of this information, there is also a design drawing and processing technology of the reducer. "Next to an expert, saw the technical data of the reducer listed at the end of the data, his face was dull, "everyone, I have a guess. Is it to process the reducer that Professor Lu developed the high-precision processing technology? "

"I'm afraid so."

Another expert said helplessly, "for example, because you want to eat eggs, you can get a hen that lays golden eggs. The world of genius is really unimaginable. "

"Compared with this kind of ultra-high precision processing technology, the reducer is a fart! This is only a small application direction of high precision machining technology. "

"I'm afraid even Professor Lu himself doesn't know how great strategic significance this high-precision machining technology has."

"If Professor Lu thinks that charging mobile phones is too troublesome, will he bring out controllable nuclear fusion technology?"

"Ha ha! Maybe it's possible! "

This ultra-high precision laser processing technology was soon verified.

The Ministry of aerospace industry immediately took this technology and produced a number 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 jubilant.

We need this technology to produce satellites, launch vehicles, aircraft, missiles, nuclear submarines and aircraft carriers

All kinds of processing equipment based on high precision laser processing technology have sprung up.

Of course, Luli's reducer design has also been widely used.

Now high precision processing equipment, are not all automation equipment? High performance reducer is also very important.

It's just Compared with the high-precision laser processing technology itself, the reducer technology is just a component technology.

Domestic high-precision processing equipment, began to comprehensively update.

Because this high-precision machining technology has been developed in China, so The negotiations with Teutonic countries on the introduction of technology have stopped completely.

Originally, Teutonic state also put on a high posture, ready to swing a knife to kill a knife, the lion big mouth general, shouting out astronomical prices.

What's more, Teutonic technology is still backward, and the machining accuracy can only reach 30 microns.

Now Sorry, we don't want it!

Teuton was stunned to learn that China did not want 30 micron precision machining technology. What's going on? Why did the rabbit suddenly stop using this technology?

Although we have eliminated the 30 micron precision machining technology, but Don't you have none?

Why don't you come here to get the knife?

At the same time, the international black market, everywhere for high-precision processing technology buyers, all disappeared for a while.

A lot of people who are going to kill the rabbit with elimination technology are so shocked that they can't understand the situation.

"Our news: Professor Lu Li, a famous scientist in China, has developed a new generation of high-precision machining technology. The machining accuracy has reached micron level, and the error is no more than one micron."

"The successful research and development of this technology marks that China has reached the world's leading level in high-precision machining technology!"

As soon as the news came out, the domestic response was flat.

Professor Lu is leading the world again. Well, that's the basic operation.

There was an uproar abroad.

The trough! The precision machining technology of flower growers has achieved an error of no more than one micron?

We are still struggling in the range of 10 microns. Are you going to be one micron?

Again Professor Lu again?

What kind of high precision processing technology do you study as a geneticist? It's no business, you know?
