Description

Technical Field

[0001] The utility model belongs to the technical field of engine parts detection, in particular to a hardness detection device for engine parts. Background Art

[0002] The hardness testing equipment for engine parts is usually a hardness tester, also known as a Rockwell hardness tester or a Brinell hardness tester. These devices measure the hardness of a material by pressing a metal ball or diamond cone into the surface of the test material.

[0003] Hardness testing can help determine the wear resistance, strength and durability of engine parts to ensure that they meet design requirements and can operate safely and reliably. These tests can also help detect whether the material is defective or deteriorated, and determine the heat treatment status of the material. Through hardness testing, manufacturers can ensure that the quality of their engine parts meets the standards and identify any quality problems in a timely manner. The problem with the above technology is that in the process of testing engine parts through a hardness tester, if the hardness of the engine parts is not enough, it is easy to cause sputtering and jumping out in all directions. The hardness tester itself does not have a component that can intercept and protect the sputtering engine parts, so there are certain safety hazards, which reduces the safety of using the hardness tester.
