Chapter 1271

"I've never seen such a shameless person like you!" Yun Fei was angry. "Security guard, come and throw this old thing out to me!"

Yunfei can't help this old thing.

Call the security guard directly outside the office and ask them to throw the old guy out. If he continues here, Yunfei, who had no heart disease, will definitely have a heart attack soon.

Huang qiaosong's shameless face set a new record here in Yunfei again.

Yun Fei doesn't like such a scene. He really doesn't like it. Only he can carry on the shameless to the end. Isn't Huang qiaosong robbing his business here?

"You don't have to call security. I'll go by myself. You can think about it seriously. If you think about it, call me anytime and turn it on 24 hours. By the way, if you agree, maybe we can really get you a pilot's license... "Huang qiaosong paid for it in order to make Yun Fei pay.

Private buying and selling of aircraft is not prohibited in China. Yun Fei has long wanted to get addicted to those fighters, but it is impossible.

Huang qiaosong said he could help Yunfei get a civilian helicopter transformed from a military transport plane, which made Yunfei very excited. However, if Yunfei wants to get a helicopter driver's license, he must ask Huang qiaosong for help. The old guy always looked like he didn't help Yunfei through the back door.

Now, even this has become a condition for Yunfei to take out the money to fund their shipborne aircraft.

"Get out of here. Nima, your driver's license is too expensive! " Yun Fei has no interest at all. He can't do such a thing with hundreds of millions of dollars to buy a flight qualification certificate.

Yun Fei is really in a bad mood today. He just learned that the military began to intervene in the cooperation between them and North Korea, and then Huang qiaosong came to him for autumn wind.

This time is not a small amount. The old thing has made it very obvious that they want 600 million dollars!

That is, the part of the cloud that should not be paid.

Although the old man talked in the middle, it was obvious that the old man was deceived by the shameless old thing Huang qiaosong.

"What's the matter with you? How did the mildew face bitterly? " Hearing that the office door was opened, Yun Fei was going to let the people who came in out, but he didn't think it was Jiang Jianxing who hadn't seen for a long time.

Yanlong commercial aircraft has been assembling the first ARJ-21 prototype during this period. As the person in charge, Jiang Jianxing has been watching the progress there. Basically, he sleeps in the workshop and office every day unless he takes a bath or something. This matter makes Zhang Cui very dissatisfied.

Yunfei also has no way. Jiang Jianxing is not like a person in charge. He is doing all kinds of logistics support for those technicians and designers every day.

"The first prototype has been assembled?" Yun Fei's face was filled with a smile.

Jiang Jianxing shook his head and saw Yunfei's eyes darkening again. He quickly explained: "the installation over there is about to be completed. I'll come back and ask you if you plan to go over and have a look..."

"Sure. When will it be finished over there? Isn't this still subject to static pressure test? " Although Yun Fei doesn't know much about aircraft production, he still knows that a new model of aircraft needs to do a lot of experiments.

Even if the prototype is produced now, it will take a long time for these aircraft to be put into commercial operation.

After the completion of various ground experiments, complex flight tests have to be carried out.

Yunfei has seen a lot of experiments on fighter planes carried out by factory 132. However, civil airliners are more rigorous than various experiments of fighter planes, which may be why China can independently design war sharp weapons such as J-10 and j-20, but has no way to produce large military transport aircraft.

China can't even think of a super big Mac like Lao maozi's An-225.

The weight of such a huge aircraft is not a small number.

"Well, take a break this afternoon and let's go there when it's almost finished. Geely's robot has made a big breakthrough recently. I plan to go to the Research Institute in the economic development zone in the afternoon to see the situation... "Things outside are annoying, but the company's internal technology continues to make breakthroughs.

Although in order to encourage the development of domestic technology and keep the Germans from chattering, the state finally gave only incomplete orders for several major automobile manufacturing processes of 91 equipment, but also gave most orders. Wang Zixin has been running at both ends of Chengdu and Northeast China.

This is because FAW Group does not believe too much in cloud technology. To change the current situation, only the welding robots ordered by Geely can be put into use as soon as possible, which can completely dispel the concerns of those officials and leave the Germans speechless.

Robot welding production line is the production process with the highest scientific and technological content and the highest degree of automation among the four major process equipment of the whole automobile. Once this has passed the acceptance of Geely Group, it can prove that there is no doubt about the strength of 91 Research Institute in this regard.

After all, the research progress of robots in their research institute, no matter how big, is experimental, not a professional robot production line.

Yun Fei also understood this, so he did not force the leaders of FAW or go to the leaders above.

If an enterprise wants to survive, it must have strong market competitiveness.

At noon, Jiang Jianxing and Yun Fei went to the economic development zone together after having dinner in the canteen of the company. The economic development zone has not become deserted because the headquarters of Yunshi holdings or Jiuyi group have been moved to the city.

There are still huge research institutions such as the 91 Research Institute and managers of various companies here.

"Xiao Yun, why are you free?" Ed Yin was surprised to see Yunfei come over without calling. Yun Fei used to live here and seldom came to the Research Institute. Now he has moved to the city. He has a lot of things to do every day. He doesn't have much time to come here at ordinary times.

"Haven't our welding robots made a breakthrough? I'll come and have a look. Although the project at FAW has a long time to go, the greater our grasp, the smaller the chance of humiliation in the future, isn't it? " Yun Fei said with a smile.

There is still no change in the 91 Research Institute. The experimental factory of the 91 automobile has not been built. All these experiments are carried out in the original area.

"By the way, did Li Shufu inform them?" Yun Fei thought that Li Shufu's more than 200 million orders played a great role in making progress so quickly. This technology is the largest batch of customized business in their research institute. It should make the people who spend money happy.

"No. It's not too late to inform our side when it is finalized and put into production. After all, no one can guarantee whether there will be any problems we haven't found. " Ed Yin said cautiously.

For him, if these technologies are not fully formed, they should not be used in production, otherwise they will not only have a great impact on customers, but also on their own reputation in the future.

After all, ed Yin used to be the winner of the national robotics center.

Yun Fei nodded and didn't speak.

Instead, he walked silently to the welding robot that was carrying out various programmed experimental actions and looked at the robot carefully.

This is no different from the robots they produced before, but they should be a lot bulky, especially some cables exposed outside. There is no sense of violation when looking at this thing.

The whole robot is divided into four parts. The bottom part is the base used to fix the position of the whole robot. The upper parts are the manipulator for moving and rotating functions, plus the welding gun at the front end.

A total of five welding robots were produced for the test, and the actions of the five robots are independent.

After all, on the automobile production line, these robots are different robots responsible for different work departments. In some places, in order to pursue efficiency, two robots symmetrically arranged are responsible for one weld, or one robot is responsible for one weld.

These are to maximize efficiency.

Naturally, we have to consider how to create the highest production efficiency at the lowest cost.

"How many infrared locators are used to detect the accuracy of the manipulator action?" Yun Fei frowned when he saw a lot of infrared detectors on the ground and a lot of shelves on the four sides of the robot“ This inspection should be in the form of positioning. Only the position of the top of the welding gun in front and the supply of welding rods should be detected. In this way, isn't it a waste to detect the rear boom and the fixed part below? "

These infrared detectors are customized products from Chengdu photoelectric research institute.

The displacement detection of these robots can be calculated according to the top point of the welding gun.

After all, these moving axes belong to linkage. As long as one axis is not in place, no matter how accurate the other axes are, it will affect the final accuracy.

Robots are the development direction of CNC machine tools, which is definitely not fun.

At least, in terms of multi axis linkage technology, CNC machine tools and robots are common. The only difference is that professional robots may need to do simple fixed actions. At the same time, the required accuracy is much lower than that of CNC machine tools. Unless we produce the automatic medical robot used to operate on humans in science fiction movies!

That kind of technology, cloud Fei believes, is unlikely to appear in the next 50 years at least.
