Description

Technical Field

[0001] The present application relates to the field of pipe body detection equipment, and in particular to a pipe body concentricity detection device. Background Art

[0002] Concentricity, the degree of deviation from the center of a circle, is a special form of coaxiality. When the measured element is the center (point) of a circle, a hole in a thin workpiece, or the axis of a shaft, the measured axis can be considered the measured point, and the degree of coaxiality between them and the reference axis is the concentricity.

[0003] The concentricity of the pipe body needs to be measured, usually using a micrometer or dial indicator. During the test, the pipe body needs to be rotated and placed, and then the probe of the dial indicator is brought into contact with the side wall of the pipe body. The pipe body is manually rotated to read the dial data, analyze it, and record it after multiple measurements.

[0004] When manual measurement operations are performed, when the tube body is pushed by manual rotation, a certain force will be applied to the tube body, causing the tube body to shake easily when it rotates. The shaking of the tube body will cause a large deviation in the results of the dial indicator test and a low detection accuracy. Utility Model Content

[0005] In order to solve the problem of low accuracy of percentage detection caused by shaking of the pipe body during manual measurement operations, the present application provides a pipe concentricity detection device.

At this time, the clamping member presses both sides of the tube body. After pressing, the dial indicator is moved to one end of the tube body. The probe of the dial indicator is located at the inner wall of the tube body. At this time, the driving member drives the tube body to rotate. During rotation, the dial indicator performs concentricity detection on the tube body. After the detection is completed, the tube body is removed.
