Abstract

The invention relates to a digital display Barcol hardness gauge which comprises a shell, a main bracket, a sensor, a pressure needle and a positioning bracket, wherein the main bracket is fixed to the shell. The digital display Barcol hardness gauge is characterized by also comprising a balance positioning device, a measurer device, a hardness value display device and a dismounting-free hardness value calibration and adjustment device. The digital display Barcol hardness gauge is rational in design, simple in structure, low in cost, easy to manufacture and convenient to use and has the characteristics of high stability, simplicity in calibration, high detection precision and the like.

Description

technical field [0001] The hardness tester involved in the present invention is specifically a digital display Barcol hardness tester used for detecting hardness values ​​of materials such as aluminum and aluminum alloys, soft metals, plastics, glass fiber reinforced plastics, rubber and leather. Background technique [0002] Due to the design structure of the currently used Barcol hardness testers, it is easy to produce measurement errors caused by deflection during detection, and it is easy to cause damage to the indenter, and it is impossible to detect cylindrical materials. The specific performance is as follows: [0003] Without a balance positioning device, it is impossible to avoid detection errors caused by deflection during detection, and it is impossible to detect cylindrical materials; [0004] There is no disassembly-free hardness value calibration technology, and the instrument calibration is cumbersome and complicated; [0005] There is no digital display dev...
