[0002] The detection of hole position is a necessary link in the manufacturing of stamping parts. In reality, for detection under high-precision requirements, a general measuring tool combination or a three-coordinate measuring machine must be used for detection. This method is time-consuming and has high requirements on the operator. Therefore, for detection under general precision requirements, in order to ensure the processing quality of the product and the smooth progress of assembly production, quality problems are discovered in time, and in order to improve inspection efficiency, special hole position gauges are often used to detect products. At present, automobile stamping parts need to be tested with hole position gauges during the production process to ensure the accuracy of the holes of automobile stamping parts.

[0003] For example, the prior art publication number is CN209840878U, which is a punching hole position gauge. The utility model drives the internal thread of the rotating disk to engage with the thread on the fixed rod through the rotation of the rotating disk, so that the fixed rod can be adjusted quickly and conveniently when measuring holes of different depths.
