Description

Technical Field

[0001] This utility model relates to the field of hardness tester technology, specifically a flexible positioning and clamping hardness tester testing fixture. Background Technology

[0002] A hardness tester is a hardness testing instrument. The principle of a hardness tester is to apply a certain pressure to the surface of an object, so that the hardness tester leaves a tiny mark on the surface with its indenter. Then, by observing the size of the mark or measuring the depth of the mark, or by calculating the diameter of the indentation produced by the hardness tester, the hardness value of the object can be obtained.

[0003] When testing objects with a hardness tester, a fixture is needed to limit and fix the object to prevent it from shifting during the test. However, common testing fixtures have poor limiting flexibility, and some testing fixtures have a simple limiting structure, making it inconvenient to adjust the limiting method according to the size and shape of the object, thus affecting the flexibility and stability of the test.

[0004] There is an urgent need for a flexible positioning and clamping tool for hardness testing to address the technical deficiencies mentioned above. Utility Model Content

A first hardness testing component, a second hardness testing component, and a third hardness testing component are sequentially installed from left to right at the bottom of the adjusting plate. A hardness tester data disk is installed at the top of the support frame.

[0007] Preferably, a support plate is fixedly connected to the support frame below the clamping frame, and the clamping frame can be placed on the support frame.

[0009] Preferably, two sets of clamping plates are provided, and the width of the clamping plates is the same as the width of the testing table.

[0010] Preferably, limit buckles are installed on both sides inside the support frame, and the limit buckles can be fastened to the outside of the clamping frame.

[0011] Preferably, the top and bottom ends of the mounting sleeve are movably connected to limit baffles, the mounting block is embedded inside the mounting sleeve, and the limit baffles are disposed at the front and rear ends of the mounting block.

[0012] Preferably, the first hardness testing component, the second hardness testing component, and the third hardness testing component are connected to the hardness tester data disk via connecting cables.
