Problems solved by technology
[0003] Existing bolts can only be measured by clamping the thread with a vernier caliper when measuring the major diameter of the thread. Not only is the operation difficult, but when the vernier caliper is used to measure the major diameter of the bolt, because the surface of the bolt has threads, the measuring claws of the vernier caliper are easy to snap in. In the groove, it is difficult to accurately measure the major diameter of the bolt, which affects the measurement result of the major diameter of the bolt

Description
technical field [0001] The invention relates to the technical field of thread detection, in particular to a detection method of a thread pitch diameter reference. Background technique [0002] Thread is the most widely used type of mechanical parts in the machinery industry. Its main purpose is to tighten, seal, transmit power and displacement. Therefore, its measurement reliability is the same as that of general mechanical parts. It is also very important. In the process of thread detection , the pitch diameter of the thread needs to be obtained, which requires measuring the major diameter of the thread and the pitch of the thread to obtain the pitch diameter of the thread by calculation. [0003] Existing bolts can only be measured by clamping the thread with a vernier caliper when detecting the major diameter of the thread, which is not only difficult to operate, but also when using a vernier caliper to measure the major diameter of the bolt, because the surface of the bo...
