Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, and more specifically, to a Vickers hardness tester tooling fixture. Background Art

[0002] The Vickers hardness tester is an instrument used to measure the hardness of materials. However, it still has some shortcomings in actual use. For example, the existing Vickers hardness tester is provided with a test bench for placing the items to be tested. However, since the items are usually placed directly on the test bench without corresponding fixing measures, the items are easily moved or tilted due to pressure during the test, resulting in inaccurate indentation position, affecting the measurement of the hardness value. In addition, the items are not firmly fixed, and are prone to sudden sliding or popping out during the test, which reduces the safety of the instrument in use to a certain extent. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a Vickers hardness tester fixture to solve the problem of lack of effective fixation when testing items in the prior art.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a Vickers hardness tester fixture, comprising a Vickers hardness tester body, the table of the Vickers hardness tester body is provided with an adjustment column, the top of the adjustment column is fixedly connected to the test table, and the Vickers hardness tester fixture also includes

[0005] Mounting seat;

[0006] A double-thread screw, the double-thread screw is rotatably mounted inside the mounting seat, and one end of the double-thread screw is fixedly connected to a rotating end;

[0007] A moving column, one end of which in the length direction is threadedly connected to the surface of the double-thread screw, and the surface of the moving column is in contact with the inner wall of the mounting seat;

[0009] Among them, it also includes a clamping plate and a limit plate. The clamping plate is fixedly connected to the side close to the connecting end in the length direction of the clamping column. The surface of the clamping plate is clamped with the end of the moving column away from the double-thread screw in the length direction. The limit plates are relatively arranged on both sides of the surface of the connecting rod, and the surface of the limit plate is slidably connected to the moving column.

[0010] It also includes a mounting component, which is arranged at the bottom of the mounting seat.

[0011] Among them, the installation assembly includes a fixing frame, a clamping block, a rotating rod, a sleeve ring, a second spring, a guide rod, and a second clamping plate. The top of the fixing frame is fixedly connected to the bottom surface of the mounting seat, the clamping block is arranged on the surface of the fixing frame, the surface of the clamping block is clamped with the front surface of the test bench, the sleeve ring is rotatably installed on one side of the bottom of the fixing frame through the rotating rod, the surface of the sleeve ring is fitted with the surface of the adjusting column, the surface of the rotating rod is set to a rough surface structure, one end of the second spring is fixedly connected to the inside of the fixing frame, the other end of the second spring is fixedly connected to the inside of the guide rod, the surface of the guide rod is fitted with the bottom of the fixing frame, the second clamping plate is fixedly connected to one end of the guide rod, and one side of the second clamping plate in the length direction is clamped with the surface of the rotating rod.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] In the above scheme, the object to be detected is placed at the corresponding position on the top surface of the test bench, and then the rotating end of one side of the mounting seat is rotated so that the double-thread screw installed inside the mounting seat can rotate synchronously, and under the limiting action of the mounting seat on the movable column, the two movable columns can move toward each other, so that the clamping column is close to the surface of the object to fix it. In addition, by moving the clamping column horizontally, the clamping plate 1 is separated from the surface of the movable column, and the connecting rod extends to the outside of the movable column. After the connecting rod moves a distance, the clamping column is rotated to face the object according to the surface shape of the object. The connecting rod is then reset by the elastic action of the spring 1, and the clamping plate 1 is re-clamped on the surface of the movable column to fix the clamping column. Therefore, not only the object is effectively fixed to avoid accidental movement or ejection under pressure during the detection process, but also the clamping column can be adjusted according to the surface shape of the object to adapt to objects with curved or straight surfaces, thereby achieving the effect of improving the practicality of the device;

[0014] By moving the second clamping plate horizontally, the second spring connected to the inside of the guide rod is deformed, and at the same time the second clamping plate is disengaged from the clamping groove provided on the surface of the rotating rod. At this time, the sleeve ring can be rotated to separate it from the surface of the adjusting column, so that the fixing frame together with the mounting seat and its corresponding components can be removed from the surface of the test bench, thereby realizing the rapid disassembly of the entire fixture, further improving the practicability of the device.
