[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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.

[0018] Reference Figure 1-3 , A wear-resistant detection device for automobile parts, comprising a base 1, a groove is opened inside one side of the base 1, a first driving motor 2 is installed in the groove, and the output shaft of the first driving motor 2 is sleeved with a bellows 3. The top outer wall of the wind box 3 is welded with an air duct 4, the end of the air duct 4 away from the wind box 3 is installed with a baffle 5 welded perpendicularly to the base 1, and the inside of the baffle 5 is provided with an air duct 6 along its height direction, and the air duct 6 Connected to the air duct 4, one side of the baffle 5 is provided with multiple sets of vent holes 7 connected to the air duct 6, and the surface of the base 1 is provided with an ash collecting groove 8, and the surface of the base 1 away from the baffle 5 is vertically welded There is a support plate 9. The support plate 9 is provided with a mounting groove on one side surface close to the baffle 5, and a push rod motor 10 is sleeved in the mounting groove. The output shaft of the push rod motor 10 is welded with a clamping plate 11, and the top of the support plate 9 is welded with The top plate 12 is arranged horizontally. A second drive motor 13 is installed on the top of the top plate 12, the output shaft of the second drive motor 13 is sleeved with a gear 14, and a slide groove 16 opened inside the top plate 12 is installed below the second drive motor 13 , The sliding groove 16 is slidably installed with a sliding block 17, the two sides of the sliding block 17 are symmetrically installed with horizontally arranged first connecting rods 18, and the two sets of first connecting rods 18 are welded with vertically arranged second The connecting rod 19, the end of the second connecting rod 19 protruding from the sliding groove 16 is connected with a U-shaped rack 15, and the gear 14 is meshed with the U-shaped rack 15 for transmission. A fixed block 20 is welded under the slider 17 and the fixed block 20 A telescopic mechanism 21 is installed at one end of the protruding chute 16, a horizontally arranged screw 22 is sleeved inside the telescopic mechanism 21, a connecting block 23 is installed under the telescopic mechanism 21, and the connecting block 23 is connected with one end of the telescopic mechanism 21 by a nut. There is a friction plate 24.

[0019] The telescopic mechanism 21 includes a first movable rod, a second movable rod, and a mounting block. One end of the first movable rod is hinged with the fixed block 20, and an end of the first movable rod away from the fixed block 20 is hinged with a mounting block, and the mounting block is away from the first movable rod. One end of the rod is hinged with a second movable rod, and the end of the second movable rod away from the mounting block is hinged with the connecting block 23. A mounting hole is opened inside the mounting block, and the mounting hole is provided with threads. The mounting hole is sleeved on the outside of the screw 22 , The screw thread is matched with the screw 22, one end of the screw 22 is equipped with a handle, and the handle is provided with non-slip threads, the telescopic mechanism 21 is provided with a through hole on the side away from the handle, and the output shaft of the first drive motor 2 extends into the air box 3 A fan blade is installed at one end of the air box 4, a communication hole connected to the air duct 4 is opened on the top of the wind box 4, a cushion pad is installed on the side of the baffle plate 5 close to the support plate 9, and a rubber pad is provided on the side of the splint 11 close to the baffle plate 5. , The wheel disc of the gear 14 is provided with half gear teeth, and the multiple sets of ventilation holes 7 are provided with 2-6 sets.

[0020] In this embodiment, firstly, the parts are placed in the dust collecting trough 8, and then the push rod motor 10 is started. The push rod motor 10 drives the clamping plate 11 to fix the parts between the baffles 5, and then starts the first drive at the same time The motor 2 and the second drive motor 13, the first drive motor 2 drives the rotation of the fan blades, blows out the wind through the ventilation holes 7, and blows the debris generated on the surface of the parts into the ash collecting trough 8, and the second drive motor 13 drives the gear 14 to rotate, and the gear 14 drives the U-shaped rack 15 to move. Because the gear 14 has only half of the teeth, the U-shaped rack 15 of the gear 14 reciprocates, and the U-shaped rack 15 drives the second The connecting rod 19 moves, and the second connecting rod 19 drives the first connecting rod 18 to move. The first connecting rod 18 then drives the slider 17 to slide back and forth in the sliding groove 16, and the slider 17 then drives the lower telescopic mechanism 21 and friction The plate 24 reciprocates, and the height of the friction plate 2 is adjusted by manually rotating the screw 22, so that the pressure of the friction plate 24 on the surface of the parts is different, so as to test the friction resistance of the parts under different pressures.

[0021] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution of the present invention Equivalent replacements or changes to its inventive concept should all fall within the protection scope of the present invention.
