[0001] This utility model relates to the field of hardness testers, specifically to an intelligent Briove hardness tester. Background Technology

[0002] The Browell hardness tester is suitable for determining the hardness of ferrous metals, non-ferrous metals, cemented carbides, carburized layers, and chemically treated layers. Its principle is to apply a load force to the test material using a stamping head and determine the hardness value of the material by observing the degree of deformation under a microscope.

[0003] A search revealed an intelligent Brinell hardness tester (publication number CN217277596U) comprising a main body, a stamping platform for testing the hardness of an object being tested mounted on the inner top wall of the main body, a testing platform on the main body, two symmetrical sliding grooves on the upper surface of the testing platform, and an installation groove connecting the two sliding grooves on the inner wall of one of the sliding grooves. A fixing mechanism for fixing the object being tested is mounted on the testing platform, the fixing mechanism including a fixing component for clamping the object being tested and a limiting component for restricting the movement of the fixing component. This invention effectively prevents the object being tested from shifting during testing.

[0004] In the aforementioned patent, the test piece is fixed horizontally, but the workpiece may still shift during testing, affecting its testing accuracy. Furthermore, the fixing method cannot adapt to different irregularly shaped test pieces, reducing the equipment's versatility.

[0005] Therefore, it is necessary to invent an intelligent Briove hardness tester to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an intelligent Briović hardness tester that achieves the effect of changing the clamping block through a multi-directional fixing and quick-release structure. This solves the problem that in the prior art, when the test piece is fixed in the horizontal direction, the workpiece may still shift during testing, affecting its testing accuracy. At the same time, it cannot adapt to different irregularly shaped test pieces when fixed, reducing the equipment's versatility.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an intelligent Briovel hardness tester, comprising a main body, a support base fixedly mounted on the main body, a test platform fixedly mounted on the top of the support base, a stamping platform located on the main body and directly above the test platform, three fixing mechanisms fixedly mounted on the top of the test platform, a protective mechanism fixedly mounted on the periphery of the test platform via a bracket, and a limit mechanism fixedly connected to both sides of the test platform. Each fixing mechanism includes a connecting block, the bottom of which is fixedly connected to the top of the test platform, a threaded rod threadedly connected to the connecting block, a movable block rotatably connected to one end of the threaded rod, the bottom of which is slidably connected to the top of the test platform, a clamping block engaging with one side of the movable block, two T-slots formed on one side of the movable block, and a T-block cooperating with the T-slots fixedly connected to one side of the clamping block.

[0008] Preferably, an L-shaped block is fixedly connected to both the front and rear ends of the top of the movable block, a blocking plate is slidably connected between the opposite sides of the two L-shaped blocks, and a blocking spring is fixedly connected between the blocking plate and the opposite side of the L-shaped block.

[0009] Preferably, the protective mechanism includes a ring frame, which is fixedly connected to the peripheral side of the test bench via a bracket, and an annular cylinder is slidably connected to the inner cavity of the ring frame.

[0010] Preferably, the annular cylinder has a hollow structure, and a plurality of compression springs are fixedly connected between the bottom of the annular cylinder and the bottom of the inner wall of the annular frame.

[0011] Preferably, the limiting mechanism includes two limiting blocks, one side of each of the two limiting blocks is fixedly connected to one side of the test platform, and a connecting rod is fixedly connected between the opposite sides of the two limiting blocks.

[0012] Preferably, a rotating cylinder is rotatably connected to the surface of the connecting rod, and a limit rod is fixedly connected to the surface of the rotating cylinder.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. The three fixing mechanisms are arranged in an isosceles triangle to fix the test piece in multiple directions, preventing it from shifting during testing. The quick-release structure of the T-slot and T-block allows for rapid replacement of the clamping blocks, adapting to different shaped workpieces and improving the equipment's versatility.

[0015] 2. By moving the limit rod away from the annular cylinder, the limit on the annular cylinder is released. The annular cylinder moves upward by the elastic force of the compression spring, so that the annular cylinder covers the periphery of the test platform, thereby protecting it during the test and preventing the test piece from breaking and flying, which could cause injury to the staff.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6The intelligent Briovel hardness tester shown includes a main body 1, a support base 2 fixedly mounted on the main body 1, a test platform 3 fixedly mounted on the top of the support base 2, a stamping platform 4 located on the main body 1 and directly above the test platform 3. The main body 1, support base 2 and stamping platform 4 all adopt existing technology. Three fixing mechanisms 5 are fixedly mounted on the top of the test platform 3. Protective mechanisms 6 are fixedly mounted on the periphery of the test platform 3 through brackets. Limiting mechanisms 7 are fixedly connected to both sides of the test platform 3. The fixing mechanism 5 includes a connecting block 51. The bottom of the connecting block 51 is fixedly connected to the top of the test platform 3. A threaded rod 52 is threadedly connected to the connecting block 51. One end of the threaded rod 52 is rotatably connected to a moving block 53. The bottom of the moving block 53 is slidably connected to the top of the test platform 3. A clamping block 54 is engaged with one side of the moving block 53. Two T-shaped grooves 55 are opened on one side of the moving block 53. A T-shaped block 56 that cooperates with the T-shaped grooves 55 is fixedly connected to one side of the clamping block 54.

[0027] The three fixing mechanisms 5 are arranged in an isosceles triangle to fix the test piece in multiple directions and prevent it from shifting during testing.

[0028] L-shaped blocks 57 are fixedly connected to the front and rear ends of the top of the movable block 53. A blocking plate 58 is slidably connected between the opposite sides of the two L-shaped blocks 57. A blocking spring 59 is fixedly connected between the blocking plate 58 and the opposite side of the L-shaped blocks 57.

[0029] The blocking plate 58 is positioned directly above the T-shaped block 56 by the elastic force of the blocking spring 59, thus limiting and fixing the T-shaped block 56. When the clamping block 54 is being disassembled or assembled, the blocking plate 58 is pulled to remove the T-shaped block 56 from the T-shaped groove 55.

[0030] The protective mechanism 6 includes a ring frame 61, which is fixedly connected to the peripheral side of the test bench 3 via a bracket, and a ring cylinder 62 is slidably connected to the inner cavity of the ring frame 61.

[0031] The annular cylinder 62 has a hollow structure. Multiple compression springs 63 are fixedly connected between the bottom of the annular cylinder 62 and the bottom of the inner wall of the annular frame 61. The annular cylinder 62 moves upward by the elastic force of the compression springs 63.

[0032] The limiting mechanism 7 includes two limiting blocks 71. One side of each of the two limiting blocks 71 is fixedly connected to one side of the test bench 3. The two limiting blocks 71 are distributed vertically, and a connecting rod 72 is fixedly connected between the opposite sides of the two limiting blocks 71.

[0033] A rotating cylinder 73 is rotatably connected to the surface of the connecting rod 72, and a limit rod 74 is fixedly connected to the surface of the rotating cylinder 73.

[0034] The ring cylinder 62 is limited by the limiting rod 74. When the ring cylinder 62 needs to be used for protection, the limiting rod 74 can be moved away from the top of the ring cylinder 62.

[0035] The working principle of this practical application is as follows:

[0036] Before use, the T-shaped block 56 is inserted into the T-shaped groove 55 to install the moving block 53 and the clamping block 54. At the same time, the blocking plate 58 is pushed by the spring force of the blocking spring 59 so that the blocking plate 58 is positioned above the T-shaped block 56 to limit and fix the T-shaped block 56, thereby ensuring the stability of the clamping block 54 during use. It is also convenient to replace the clamping block 54 with different shapes according to different irregular workpieces. The operation is simple and practical.

[0037] When in use, the test piece is placed on the test bench 3. By rotating the threaded rod 52, the threaded rod 52 drives the moving block 53 to move, and the moving block 53 drives the clamping block 54 to move. The test piece is fixed by the three clamping blocks 54 to ensure its stability during testing.

[0038] During testing, the limit rod 74 is moved away from the annular cylinder 62, releasing the limit on the annular cylinder 62. The annular cylinder 62 moves upward by the elastic force of the compression spring 63, covering the periphery of the test platform 3, thus protecting it during testing and preventing the test piece from breaking and causing injury to the staff.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
