Detection tool for detecting roll collar

Abstract

The invention provides a detection tool for detecting a roll collar. The detection tool comprises a fixing structure and a measuring structure, wherein the fixing structure comprises a handle and a connecting part, the handle is in a cylindrical shape with different diameters, and is used for being held by a worker, the connecting part is in the shape of an equal-diameter cylinder, one radial endof the connecting part is fixedly connected with the handle, the other radial end of the connecting part is fixedly connected with the measuring structure, the measuring structure comprises a rod bodystructure, and the rod body structure is a cylinder with the same diameter. According to the invention, the rod body structure is assembled and matched with the roll collar, so that the detection ofthe roll collar is realized; the detection tool is used for checking and accepting the inner holes of the roll collars, checking and accepting quality meets requirements, and checking and accepting efficiency is improved by about 10 times compared with vernier caliper measurement checking and accepting; and continuous points of the inner diameter can be detected at one time by using the cylindrical spacing of the rod body structure, so that the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of inspection and acceptance of finished products, and in particular relates to a checking tool for roll ring detection. Background technique [0002] During the production and manufacturing process of Kocks roller rings, Kocks roller rings are produced after complex manufacturing processes. During the manufacturing process, the roller rings undergo multiple flaw detection tests to ensure the inherent quality of the roller rings; similarly, during use, the Kocks roller rings The inner hole size of the roller ring also has high precision requirements. Therefore, when the roller ring is purchased and returned to the factory, it is also necessary to measure the inner hole of the roller ring to check whether the size is qualified. [0003] When measuring and checking the size of the inner hole of the roll ring, a vernier caliper is generally used to measure and check whether the size of the inner hole is qualifi...

AI Technical Summary

Problems solved by technology

[0004] (1) Using a vernier caliper can only measure the diameter of the inner hole, it is difficult to find two points of the diameter of the inner hole, and the measurement error is large;

[0005] (2) It is difficult to measure the roundness and coaxiality of the inner hole with a vernier caliper;

[0006] (3) For the diameter of the inner hole ∮215, the tolerance is H6, and the width is 40mm and 75mm. When the inner hole width of the roller ring is up to 75mm, the vernier caliper can only measure the size of individual points in the width direction, and cannot measure the width direction. size of consecutive points

[0007] (3) For the vernier caliper itself, the measurement accuracy of the vernier caliper is 0.02mm, and there will be measurement errors during the actual measurement process. The actual measurement error is greater than 0.02mm, and the measurement accuracy cannot meet the tolerance requirements of the design;

[0008] (4) If you want to measure the size of continuous points, you need a vernier caliper to measure point by point. Therefore, using a vernier caliper to measure is inefficient and the workload is large
