Cars are very common in our life, but the manufacture of a car is not simple and requires many steps to complete. Automobile Gauge Reference Ball is one of them. Automobile Gage Reference Ball is a testing tool specially manufactured according to specific requirements. At present, the processing of Automobile Gage Reference Ball has become an indispensable technology in modern automobile manufacturing. . Let's understand the characteristics of the benchmark ball processing technology for automobile inspection tools.

The inspection of the reference ball of the automobile inspection fixture, many important holes and flanges in the body stamping parts need to be inspected separately. Add a boss with a thickness of about 1mm on the surface. The center of the boss is on the same axis as the center of the workpiece hole, and the diameter is 5mm larger than the hole diameter. The two-line method is used for detection on the boss. When the accuracy of the hole to be measured is required, the plug gauge and bushing are used for detection through the positioning hole method.

Regarding the design of the floor assembly of the reference ball of the automobile inspection tool, the upper surface of the inspection body extends a certain distance along the direction of the reference plane, so that its low point is greater than the thickness of 150mm , while ensuring that the inspection body has sufficient strength, the bottom surface of the inspection body, that is, the upper surface (basic surface) of the floor assembly becomes the integer position of the vehicle body coordinate system. I-beam), positioning block and casters. After the circuit board is fixed by the test piece, other parts can choose standard models according to the actual situation.

In the production process of the reference ball of the automobile inspection tool, the trimming and blanking process has always been a difficult point in the mold manufacturing process, especially for some complex structures such as oblique cutting, Heavy-duty automobile molds such as oblique punching and oblique turning. It is very difficult to determine the boundary line using the traditional production method, and it needs to be explored again and again, which brings a huge workload to the jig and processing equipment, not only puts forward high requirements on the skill level of the jig, but also seriously affects the quality of the jig. Mold debugging in the follow-up process. In addition, in reality, considering the cost, the cutting edge material of most trimming parts and punching dies is made of alloy steel. Avoided, as the material tends to break during multiple overlays, the blade is scrapped and the material reused.

The reference ball of the automobile inspection tool adopts laser cutting technology. For the developed automobile parts, after the pattern parts are successfully drawn and formed, laser cutting is carried out instead of trimming and punching processes , cut along the edge trimming of the automobile inspection parts, and directly trial-manufacture the cut samples for the next flanging process, so that the whole process of the polishing machine saves two processes, completely changes the traditional single-line serial production method, and greatly shortens the process , reducing the cost of mold making.
