Equipment for measuring article hardness

Abstract

The invention discloses a device for measuring the hardness of objects, which comprises a base, a loading plate, a pressing plate, a second fixing plate and a control box. A support plate is installed on one side above the base, and the other side above the base is A control box is installed on the side, and a display screen is installed at one end of the control box. First fixing plates are installed on the bases on both sides of the support plate, and a second fixing plate is installed above the first fixing plate. A motor box is installed on the side close to the control box above the second fixing plate, and a pressure sensor is installed below the loading plate. The invention is equipped with a fixing mechanism composed of a screw tube, a screw rod and a splint, which can fix the objects to be tested in different sizes and shapes on the loading plate, avoiding that the objects to be tested cannot be fixed, so that the objects to be tested can be easily entered from the The slide on the stage affects the normal progress of the detection process and effectively improves the stability of the device.

Description

technical field [0001] The invention relates to the technical field of hardness measuring equipment, in particular to a device for measuring the hardness of objects. Background technique [0002] The hardness value indicates the ability of a material to resist hard objects being pressed into its surface. It is one of the important performance indicators of a material. Generally, the higher the hardness, the better its wear resistance. Commonly used hardness indicators include Brinell hardness, Rockwell hardness and Vickers hardness. When measuring the hardness of materials, a hardness tester is needed. However, most of the existing hardness testers lack corresponding fixing mechanisms. When the test object is placed on the loading plate, the test object cannot be fixed, so that When the hardness tester detects the object to be tested with irregular shape, the object to be tested is easy to slip off the stage, which affects the normal progress of the detection process, and th...

[0002] The hardness value indicates the ability of a material to resist hard objects being pressed into its surface. It is one of the important performance indicators of a material. Generally, the higher the hardness, the better its wear resistance. Commonly used hardness indicators include Brinell hardness, Rockwell hardness and Vickers hardness. When measuring the hardness of materials, a hardness tester is needed. However, most of the existing hardness testers lack corresponding fixing mechanisms. When the test object is placed on the loading plate, the test object cannot be fixed, so that When the hardness tester detects the object to be tested with irregular shape, the object to be tested is easy to slip off the stage, which affects the normal progress of the detection process, and the load value of the existing hardness tester cannot be adjusted, making the device unsuitable for Materials with different hardness. At the same time, most of the indenters of existing hardness testers cannot be replaced. When the indenter is damaged, the whole device needs to be replaced, which not only affects the efficiency of testing, but also increases the cost of testing.
