Description

Technical Field

[0001] The present invention relates to the technical field of automatic equipment, and particularly to a fully automatic thread plug gauge inspection machine. Background Art

[0002] Threaded parts are one of the earliest simple machines invented by humans. In ancient times, humans used threads to fix the armor of battle robes, press oil, and make wine. Due to the ease of assembly and disassembly of threads, they are still widely used in various mechanical manufacturing fields today. The inspection of threaded products is an unavoidable topic for each enterprise.

[0003] Thread gauges, also known as thread plug and ring gauges, are usually used to inspect and determine whether the dimensions of threads are correct. Thread dimensions consist of thread diameter and pitch. Usually, when selecting a thread gauge, it is necessary to know the thread specification to be inspected. Thread gauges are divided into thread plug gauges and thread ring gauges according to the internal and external threads to be inspected. A thread plug gauge is a tool for measuring the correctness of internal thread dimensions and can be divided into three types: ordinary coarse pitch, fine pitch, and pipe threads. A thread ring gauge is used to measure the correctness of external thread dimensions, with one go-end and one not-go-end.

[0004] By using a go-end thread gauge to inspect the screwing ability of a threaded workpiece, the internal thread hole can be conveniently and quickly inspected. The go-gauge of the thread gauge can be rotated at any position of the threaded part to be measured. If it can pass through the entire thread length, it is judged as qualified; otherwise, it is an unqualified product. However, at present, most inspections of threaded workpieces are carried out by manually rotating the thread gauge, which is cumbersome and inefficient. Summary of the Invention
