Abstract

The invention aims to provide a Brinell hardness indentation diameter measurement auxiliary device which comprises a bottom plate and a measurement microscope, an annular clamp is clamped in an annular groove, the annular groove is fixedly installed on the measurement microscope, the annular clamp is connected with a first horizontal telescopic rod and a second horizontal telescopic rod, and the first horizontal telescopic rod is connected with a first vertical telescopic rod. The end of the first vertical telescopic rod is connected with a first magnetic suction cup, the second horizontal telescopic rod is connected with the second vertical telescopic rod, the end of the second vertical telescopic rod is connected with a second magnetic suction cup, a center round hole is formed in the bottom plate, and the first magnetic suction cup and the second magnetic suction cup are arranged on the bottom plate. According to the invention, the problem that a small-size part with a small Brinell indentation edge reserved space is easy to shake left and right below a measuring microscope base is solved; the problem of relative movement between the measuring microscope and the part caused by artificial and part factors is solved; measurement errors caused by human factors and part materials and size factors are greatly eliminated.

Description

Technical field[0001]The present invention relates to a test device, specifically a hardness test device.Background technique[0002]In the manufacturing industry, the hardness detection of metal materials is very critical. Whether it is a metal material production plant or a processing plant, it will detect the metal material for forging metal materials, to control the quality of the metal material. The metal material briceard hardness test method is: a certain test force is applied to a hard alloy of a diameter, pressed into the surface of the test sample, and then remove the test force, and measure the diameter of the sample, and then passed Check the table and calculate the bricenet hardness value of the sample. During the Bank hardness measurement, the read number microscope used in the measurement is measured in the direction of the samples, each of which is perpendicular to each other, and takes the average value as "indential diameter", and finally checks the table. During nor...
