Abstract

The utility model relates to the technical field of testing equipment, and in particular to a sample stage of a Brinell hardness tester, comprising a main body, a bracket fixedly connected to the surface of the main body, and a bottom plate fixedly connected to the surface of the bracket. The utility model uses a fixing mechanism to fix the sample stage of the Brinell hardness tester to prevent the sample from moving during testing and affecting the test result. When using the Brinell hardness tester, the tester pushes the dial to the left, and the dial causes the center column to rotate. The adjustment disk fixedly connected to the surface of the center column will also rotate, and the clamping block movably connected to the surface of the adjustment disk will be pushed to slide to both sides, so that the support column fixed to the surface of the clamping block is opened. At this time, the sample to be tested is placed on the surface of the carrier, and then the dial is released. The spring connected to the surface of the clamping block through the connecting column will pull the clamping block to drive the support column to clamp the sample through the anti-skid pad. After the test is completed, the dial is pushed to release the sample by the anti-skid pad to remove the sample.

The process is simple, ensuring that the clamping block can be pulled by the spring to run along the expected trajectory, so that the sample stage of the Brinell hardness tester has the effect of fixing the sample.

[0009] As a preferred technical solution of the utility model, the surface of the clamp block is movably connected to the surface of the side plate, which fixes the clamp block more tightly, prevents the clamp block from shifting during movement, and reduces the occurrence rate of failures.

[0010] As a preferred technical solution of the utility model, the surface of the lever is movably connected to the surface of the base plate, so that the lever can run according to the expected trajectory, ensuring that the sample stage of the Brinell hardness tester can open the fixing mechanism by moving the lever, which is more convenient to use.

[0012] The beneficial effects of the utility model are:

[0013] The sample stage of the Briaudevier hardness tester can fix the test sample through a fixing mechanism to prevent the sample from moving during testing and affecting the test result. When using the Briaudevier hardness tester, the tester pushes the dial to the left, and the dial causes the center column to rotate. The adjustment disk fixedly connected to the surface of the center column will also rotate, and the clamping block movably connected to the surface of the adjustment disk will be pushed to slide to both sides, so that the support column fixed on the surface of the clamping block will open. At this time, the sample to be tested is placed on the surface of the carrier plate, and then the dial is released.
