Thread ring gage and machining process thereof

Abstract

The invention discloses a thread ring gage. The thread ring gage comprises an outer ring part and an inner ring part nested in the outer ring part. The inner ring part is a cemented carbide ring. An internal thread corresponding to a thread to be measured in specification is formed on the inner wall of the cemented carbide ring. When the thread ring gage is applied, since the internal thread of the thread ring gage is made of cemented carbide which has excellent hardness and strength, the abrasion resistance of the cemented carbide internal thread is remarkably improved compared with the abrasion resistance of a common thread ring gage made of tool steel. Meanwhile, since the cemented carbide has good corrosion resistance, the corrosion resistance of the thread ring gage is also greatly improved. Moreover, measuring accuracy is guaranteed effectively, and the service life of the thread ring gage is prolonged. The invention further provides a thread ring gage machining process for machining the thread ring gage.

Description

technical field [0001] The invention relates to the technical field of detection tools, more specifically, to a threaded ring gauge, and to a processing technology of the threaded ring gauge. Background technique [0002] In order to ensure product quality, every part in machining must be manufactured according to the tolerance requirements specified on the drawings. It is far from enough to rely on human sensory organs or simple ruler detection, and it must be measured with the help of measuring tools with certain precision. Therefore, in order to obtain higher measurement accuracy, it is necessary to improve the accuracy of the measurement tool. [0003] The thread ring gauge is a commonly used measuring tool, which is used to measure the correctness of the external thread size of the workpiece. In order to make the measuring tool have high detection accuracy, the material selection should focus on the impact on the wear resistance, dimensional stability, machinability a...
