The output shaft of the electric push rod 506 drives the lower pressure plate 507 to move downward and press the carbide block body 504 down and fix it on the upper surface of the placement disk 4.

[0032] See also Figure 4 In order to facilitate the wear resistance test of the carbide block body 504 with different outer diameters, in this embodiment, the adjustment mechanism 6 includes a fixed plate 601 arranged on the left and right sides of the upper surface of the support frame 2, and the internal thread of the fixed plate 601 is connected to the threaded rod 602, and the left and right threaded rods 602 are provided with a handle 603 on the opposite side.

[0033] In this embodiment, the threaded rod 602 is driven to rotate inside the right fixed plate 601 by twisting the handle 603 on the right side, and the wear-resistant plate 605 is driven to move to the left. The left side of the wear-resistant plate 605 contacts the right side of the rotating carbide block body 504, and then the wear resistance test is performed. The wear resistance of the carbide block body 504 is judged by the degree of wear of the carbide block body 504.

[0035] It should be noted that the left or right wear-resistant plate 605 can be driven to move left and right, so as to test the wear resistance of the cemented carbide block bodies 504 with different outer diameters.

[0036] The working principle of the above embodiment is:

[0037] (1) When testing, the carbide block body 504 can be slidably inserted into the outer side of the second fixed cylinder 503, and the electric push rod 506 is started. The output shaft of the electric push rod 506 drives the lower pressure plate 507 to move downward and press the carbide block body 504 down and fix it on the upper surface of the placement plate 4. By starting the motor 3, the output shaft of the motor 3 drives the placement plate 4 to rotate, and then the carbide block body 504 that is pressed down and fixed can be driven to rotate. At this time, by twisting the handle 603 on the right side, the threaded rod 602 is driven inside the right fixed plate 601. It rotates and drives the wear-resistant plate 605 to move to the left. The left side of the wear-resistant plate 605 contacts the right side of the rotating carbide block body 504, and then the wear resistance performance test is carried out. When the carbide block body 504 is worn, it means that the wear resistance performance is general. At the same time, the carbide block body 504 with a smaller inner diameter can be slidably inserted on the outside of the limit rod 501. At the same time, the carbide block body 504 can also be slidably inserted on the outside of the first fixed cylinder 502, which is convenient for fixing carbide blocks with different inner diameters and conducting wear resistance performance testing.

[0038] (2) When the wear-resistant plate 605 on the right side is worn, the handle 603 on the left side can be rotated to drive the wear-resistant plate 605 on the left side to move to the right, and then the wear resistance performance of the cemented carbide block body 504 can be tested. At the same time, by twisting the left or right handle 603, the wear-resistant plate 605 on the left or right side can be driven to move left and right, so as to test the wear resistance performance of cemented carbide block bodies 504 with different outer diameters.
