AI Technical Summary

Technical Problem

The existing pump shaft detection tool cannot detect whether there are cracks on the side walls of the threaded holes at both ends of the pump shaft, which will affect the service life of the pump shaft.

Method used

A pump shaft inspection tool is designed, including a U-shaped plate, a placement assembly and a detection assembly. By inserting the pump shaft into the inside of the placement cylinder, blow air into the threaded hole using the air pump, and judge whether there are cracks on the side wall of the threaded hole through the pressure sensor.

Benefits of technology

It realizes effective detection of the side walls of the threaded hole of the pump shaft, improves the detection efficiency, and can detect four pump shafts at the same time, which is simple and convenient to use, and solves the problem that existing devices cannot detect cracks on the side walls of the threaded hole.

Abstract

The utility model discloses a pump shaft detection tool, which belongs to the technical field of pump shaft detection tools, solves the problem that the existing device cannot detect whether the side walls of threaded holes at the two ends of a pump shaft have cracks, and comprises a U-shaped plate, a placement assembly is arranged on the bottom surface of the U-shaped plate, a detection assembly is arranged right above the placement assembly, and the detection assembly is connected with the U-shaped plate. The detection assembly comprises an air cylinder fixedly installed on the top face of the U-shaped plate, the output end of the air cylinder penetrates through the top face of the U-shaped plate and is fixedly provided with a pressing disc, and the bottom face of the pressing disc is provided with an air inlet hole with the same size as a threaded hole of the pump shaft. Whether the side wall of the threaded hole of the pump shaft is cracked or not is judged by observing whether the numerical value of the pressure sensor is reduced or not, so that the purpose of conveniently detecting the side wall of the threaded hole of the pump shaft is achieved, the detection efficiency of the pump shaft is improved, and the device is simple and convenient to use.
