The quality of the inspection fixture directly affects the inspection quality of the product. Now a self-counting inspection fixture for automobile sheet metal parts is needed.

[0003] First, the gauge needs to be installed before use. The installation steps of existing gauges are often complicated and prone to displacement, which reduces the overall stability of the gauge. Secondly, the gauge needs to clamp the sheet metal when in use. Since the sizes of sheet metal are different, the versatility of the gauge is required to be high. The existing gauge is not convenient enough to clamp the sheet metal, which makes it impossible for the gauge to clamp and fix sheet metal of different sizes, greatly reducing the versatility of the gauge. Thirdly, the gauge needs to automatically count the number of inspections when in use. Existing gauges usually do not have the function of automatic counting when in use, which easily leads to the use of the gauge exceeding the prescribed number of times, resulting in reduced accuracy, and cannot effectively control the number of parts completed by employees in a single day and count the CMM re-test cycle of the gauge, thereby reducing the service life of the gauge.
