Chapter 900 (2/2)

This technology is too advanced and important. If politicians happen to be sitting in the car. Under special circumstances, the tire was blown out. You can borrow the car inflation system to buy more time so that the killer can't take advantage of it.

At this time, many rich people have a strong interest in the new military vehicle of heiyun, which can protect their lives. As long as you drive this car out, your family can rest assured.

The last picture was mainly shot inside the Detroit black cloud automobile factory. At the beginning, black cloud engineers were producing parts. A row of large CNC machine tools appeared in front of us, and many people saw it for the first time. The processed parts are simply works of art, which shows the machining accuracy of the machine tool.

After the parts were produced, engineers began to test with various instruments; Then summarize to the assembly workshop.

There was no bright spot in the assembly of other parts, but when the engine was assembled, people saw engineers working in specific protective clothing. At this time, the temperature in the assembly workshop is displayed as minus 50 degrees. In other words, the engine should be assembled at minus 50 degrees.

Knowledgeable people immediately understand what it means. The engine is combined with the shaft through holes to ”piece together” into a complete machine. Some need riveting and others need screws to be tightened.

When it comes to hole shaft fit connection, it is necessary to consider the different gap sizes of different parts. For example, the piston and cylinder block can be regarded as ”hole shaft” connection, in which the gap should not be too large or too small. The original intention of reasonable engine gap production is divided into three types, one is reasonable gap fit, one is transition fit, and the other is interference fit.

The interference fit needs to be assembled at low temperature, and the engine can work at high temperature after low temperature assembly.

At this time, the audience in front of the TV was shocked by the powerful technology of black cloud again. No wonder the performance of black cloud car is so superior. Other car companies can't just assemble the engine, which requires huge capital investment; And enterprises that really understand technology and consider for consumers will do it.

During the assembly process, the audience saw many professional tools. Including the 16 linkage screwdriver for sealing the cover, the whole engine cover can be sealed at one time. This can not only improve work efficiency, but also achieve force balance.

So that the stress at each point is the same, and there will be no loose screw, which will lead to problems in the whole engine.

After the engine was assembled, the engineer checked it in detail. Then the engine nameplate will be stamped with the steel seal of its own code. Although it is separated from the mask, the engineer's satisfied smile can still be seen.

It seems that the engineer is very satisfied with the engine he has assembled, otherwise he wouldn't have such a confident smile.

After the engine is assembled, the quality inspector starts detailed inspection. If there is no problem, stamp the steel seal under the assembly engineer code to prove that the engine has passed the inspection. If there is a problem, both people will be held accountable.

Next, start to assemble the whole vehicle, and the engineer will hoist the engine, gearbox and other core components; Assemble with the aid of equipment.

Basically similar to other enterprises, there is no novelty. However, one thing impressed the audience is that the large pieces built by each group of heiyun automobile will have the steel seal of the corresponding engineer and quality inspector code.

In other words, the responsibility belongs to the person. If there is a problem, the party concerned can be found at the first time. Although it will waste some time, it is also in a responsible attitude to consumers; This craftsman spirit is worth learning from all walks of life.

After complex assembly, a new car appeared in front of the audience. At this time, everyone lamented that the original car was produced in this way. Look simple; The science and technology contained in it was unthinkable before. It seems that heiyun cars are expensive. It's really expensive.

Engineers working at minus 50 degrees alone can accept such a responsible attitude, which is 20% more expensive than other cars.

After the vehicle is assembled, various tests are carried out directly in the test yard. The driver carried out a series of complex operations in the black cloud internal test field, but did not attract special attention. After all, I've seen too many wonderful pictures before, and the audience's light has become very picky.
