After this cycle, the sandpaper 27 can be fully utilized and resources can be reasonably used to avoid waste.
[0029] like Figure 1 and Figure 4 As shown, the fixing assembly 8 includes a fixed installation box 16 fixedly installed at the bottom of the movable seat 7, and a limit plate 20 is installed on the inner side of the installation box 16.

[0030] like Figure 2 and Figure 3 As shown, the reciprocating assembly package is fixedly mounted on two guide rails 22 on the top of the workbench 1, and a mounting plate three 26 is movably provided between the two guide rails 22.

[0034] Working principle:
[0035] First, stick the sandpaper 27 on the top of the mounting plate 3 26, and then place the sample body 18 to be tested inside the mounting box 16 before using the friction and wear tester, so that one side of the sample body 18 is close to the limiting groove 21, and then rotate the adjusting rod 17, so that the adjusting rod 17 drives the fixing plate 19 to approach one side of the sample body 18, and then fix the sample body 18 between the fixing plate 19 and the limiting plate 20, and then manually rotate the screw 29, so that the rotation of the screw 29 drives the external moving seat 27 to move, and then in the process of moving, the position of friction with the bottom sandpaper 27 can be arbitrarily selected to avoid the friction track in the stroke avoiding the friction track in front. After this cycle, the sandpaper 27 can be fully utilized to reasonably use resources to avoid waste. When the position is selected, the external The power supply is used to drive the motor 15, so that the output shaft of the motor 15 drives the screw 10 to rotate, and then the movable seat 4 outside the screw 10 moves downward during the rotation. During the movement, the sample body 18 fixed inside the fixed component 8 contacts the sandpaper 27. At this time, the downward pressure of the sample body 18 moving downward and contacting the sandpaper 27 can be observed through the pressure gauge 6. Then the motor 2 23 is driven, so that the output shaft of the motor 23 drives the turntable 24 to rotate, and then during the rotation, the centrifugally connected connecting rod 25 pushes the mounting plate 3 26 to move inside the guide rail 22, and then during the movement, the sandpaper 27 on the top of the mounting plate 3 26 is rubbed back and forth with the sample body 18. The motor 2 23 uses a speed-regulating motor to facilitate the testing of different friction speeds of the sample body 18.
