Cylindrical part fixing method suitable for measurement of Shaw hardness tester

Abstract

The invention discloses a cylindrical part fixing method suitable for the measurement of a Shaw hardness tester. The method comprises the following steps: S1: arranging a base on a Shaw hardness tester stand; S2: arranging a left slide block and a right slide block at two sides of a stop block, wherein both the left slide block and the right slide block can move along a guide groove; S3: installing a left adjusting plate on the left slide block, and installing a right adjusting plate on the right slide block; S4: installing a fixed supporting portion on one end, close to the base, of an adjusting groove, and installing a movable supporting portion on the other end; S5: arranging a component to be measured on two opposite fixed supporting portions, rotating a screw I at two sides of the stop block, and adjusting a distance between the two fixed supporting portion; and S6: enabling the movable supporting portion to slide in the adjusting groove, adjusting the movable supporting portion at an appropriate height, pressing and fixing the component to be measured, and performing the measurement. By adopting the method, the measurement can be stably performed, the measurement error can be reduced, and the method is suitable for cylindrical components of different sizes and has the advantages of good reliability and wide application range.

Description

technical field [0001] The invention relates to a fixing device, in particular to a method for fixing a cylindrical part suitable for the measurement of a Shore hardness tester. Background technique [0002] For a product, many of its parts must have a certain hardness, otherwise, its parts may be deformed or have some kind of problem in the assembly before leaving the factory, so that the product cannot leave the factory, or after leaving the factory due to a certain part Parts are not wear-resistant and cannot be used. Therefore, the hardness test of the parts of the product is extremely important in production. [0003] Hardness tests mainly fall into two categories: metal and nonmetal. Many products need to know the hardness of its parts. For example, if the hardness of a mold is not enough, it will wear out quickly; It is often necessary to measure its hardness when it is made into a shell. The parameter for measuring the hardness of steel is called Rockwell hardnes...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that when the hardness of a columnar part is measured by a Shore hardness tester, if it is not fixed, it is easy to generate vibration and cause a large error in the test result. The purpose is to provide a cylindrical part suitable for the Shore hardness tester Fixing method to solve the above problems
