What is the car checking fixture for?
When it comes to car checking fixtures, some people may not be sure what they really are. I believe that cars are well-known to the public, ranging from octogenarians to three-year-old children. Today, cars have become one of the important means of transportation for people, but there are still many people who do not know how cars are made.
According to data, after the establishment of the People's Republic of China, Changchun First Automobile Manufacturing Factory was established in 1953, and on July 14, 1956, China's first Jiefang brand truck was produced.
With the continuous development of China's automotive industry, more and more independent brands have emerged, and the manufacturing technology and process of automobiles are also constantly updated and improved. With the continuous updating and transformation of processes, automotive checking fixtures have been derived. So what is the automotive checking fixture?
The manufacturing process of automobiles is very complex, and the production process of different parts is different. For example, for exterior or structural parts of automobiles, after confirming the selection of raw materials, they are produced through specialized molds. When the parts are molded into samples by molds, it is necessary to check whether the dimensions of the parts meet the set requirements. Previously, calipers or steel rulers were used to measure them. Later, YVM or CMM inspection appeared. In practice, it takes a long time to know the results when YVM or CMM inspection is used to measure a part. The technical personnel came up with a faster way, which is the commonly used automotive parts checking fixture, which can quickly and accurately detect parts.
There is also a detection fixture used to measure some relatively irregular parts, which is mainly used to fix the product and set the base assembly, making it convenient to use CMM or imaging instrument to detect the product.
The above content is a simple answer to the question of what automotive checking fixtures are, because the manufacturing of inspection fixtures or fixtures itself also has certain technical requirements. For specific content, you can refer to the official website of FIFM checking fixtures to find more answers and a more comprehensive understanding of what automotive inspection fixtures are?
