[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figure 1 、 Figure 5, an embodiment provided by the present utility model: an anti-wear test tool for wear-resistant coatings, including a workbench 1. The workbench 1 is a wear-resistant detector, and this technology is an existing technology. Since this technology is an existing technology and is a conventional technology in this field, it will not be described in detail in this case. A fixing rod 10 is fixedly connected to the upper surface of the workbench 1. A clamping assembly is rotatably connected to the outer surface of the fixing rod 10. The clamping assembly is used to clamp and fix the test object, so that the test object can rotate within a fixed position. The clamping assembly includes a spring 9 and a housing 2. Two fixing plates 3 are fixedly connected to the upper surface of the workbench 1, and a control housing 6 is arranged inside the fixing plates 3. The two control housings 6 are respectively fixed to the two side fixing plates 3, and the control housing 6 can rotate within the fixing plate 3. A motor is arranged inside the control housing 6 and is electrically connected to the workbench 1. In addition, the output shaft of the motor in the control housing 6 is fixed to the rotating rod 12, and the rotating rod 12 is driven to be fixed through it, so that the grinding disc 7 can perform the detection work on the test object. A dust suction rod 4 is arranged between the two fixing plates 3. The dust suction rod 4 can also rotate within the two fixing plates 3. The dust suction rod 4 is provided to suck away the flying debris generated by friction during the operation of the machine. The dust suction rod 4 and the workbench 1 are electrically connected, and the work of the dust suction rod 4 can be controlled by operating the workbench 1. And this technology is an existing technology. A rotating assembly is penetrated and rotated inside the control housing 6. The rotating assembly will drive the grinding disc 7 to polish the test object. The rotating assembly includes a grinding disc 7 and a rotating rod 12. A rectangular groove 15 is arranged on the outer surface of the grinding disc 7. The rectangular groove 15 is provided to fix the grinding disc 7 on the outer surface of the rotating rod 12. The shrinkage block 14 is clamped on the inner wall of the rectangular groove 15. When the grinding disc 7 is installed on the outer surface of the rotating rod 12, the shrinkage block 14 slides outwards and is clamped in the rectangular groove 15. When the rotating assembly rotates, it can drive the grinding disc 7 to rotate and thus friction the test object.

[0031] Refer to Figure 4 , Figure 6 , the rotating assembly further includes a shrinkage block 14, a threaded rod 13, a moving block 16, and a rectangular block 17. The rotating rod 12 penetrates and rotates inside the control housing 6. Before the machine is started, the control housing 6 is in a vertical state and the rotating rod 12 remains stable inside the control housing 6. The control housing 6 is pulled down to drive the rotating assembly to be in a horizontal state. After the machine is started, the rotating rod 12 rotates inside the control housing 6. The shrinkage block 14 penetrates and is slidably connected to the outer wall of the rotating rod 12. The shrinkage function of the shrinkage block 14 is to fix the grinding disc 7, drive the grinding disc 7 and the rotating rod 12 to move together without falling. The upper end of the moving block 16 is hinged to the lower surface of the shrinkage block 14, and the lower end of the rectangular block 17 is hinged to the moving block 16. When the threaded rod 13 rotates, it can drive the rectangular block 17 to move horizontally. The threaded rod 13 penetrates and is threadedly connected to the inner wall of the rectangular block 17, and the threaded rod 13 is threadedly connected to the left surface of the rotating rod 12.

[0032] Refer to Figure 2 , Figure 3, the clamping assembly further includes an arc block 8. The outer shell 2 is rotatably connected to the outer surface of the fixed rod 10. When in the non-working state, the outer shell 2 is in the open state. The object to be detected is placed, and the outer shell 2 contracts inward. When contracting, the object to be detected compresses the arc block 8. A slope 11 is provided on the lower surface of the arc block 8. The arc block 8 is slidably connected to the inner wall of the outer shell 2. The arc block 8 is fixedly connected to the lower end of the spring 9. When the arc block 8 is compressed, it squeezes the spring 9. The elastic force of the spring 9 causes the arc block 8 to press downward to clamp the object to be detected. A dust suction groove 5 is provided on the front surface of the dust suction rod 4. The upper end of the spring 9 is fixedly connected to the lower surface of the outer shell 2.

[0033] Working principle: When in use, first open the outer shell 2 along the fixed rod 10 and put the object to be detected on the center of the workbench 1. Then, squeeze the object to be detected inward. Since the inner wall of the arc block 8 is provided with a slope 11, during the squeezing process, the slope 11 is subjected to pressure, causing the arc block 8 to move upward and squeeze the spring 9. The spring 9 presses the arc block 8 tightly due to its own elastic force until the outer shell 2 is completely closed.

[0034] Pull the dust suction rod 4 downward along the inner wall of the fixed plate 3. After putting down the dust suction rod 4, rotate the threaded rod 13 to move the threaded rod 13 outward from the rotating rod 12. The threaded rod 13 drives the rectangular block 17 to move, and at the same time, the moving block 16 hinged on the rectangular block 17 contracts inward. The other end of the moving block 16 is hinged on the surface of the contracting block 14, so the contracting block 14 is pulled to contract inward toward the inner side of the rotating rod 12. At this time, put the grinding disc 7 in. After putting the grinding disc 7 in, rotate the threaded rod 13 in the reverse direction to move the threaded rod 13 toward the inner side of the rotating rod 12. The moving block 16 pushes the contracting block 14 to move outward and slide into the inner wall of the rectangular groove 15 on the outer surface of the grinding disc 7. When the two grinding discs 7 are fixed, pull the two control shells 6 downward along the fixed plate 3 at the same time until the outer surface of the grinding disc 7 contacts the object to be detected.

[0035] Start the workbench 1. At this time, the output shaft of the motor in the control shell 6 drives the rotating rod 12 to rotate. Since the grinding disc 7 is fixed on the rotating rod 12 by the contracting block 14, when the rotating rod 12 rotates, it drives the grinding disc 7 to rotate together to rub the object to be detected. During the rubbing process, chips are generated. When the chips are generated, they are sucked into the dust suction groove 5 by the dust suction rod 4 to prevent the chips from flying out, and the detection result is presented through the workbench 1.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
