[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a clutch friction performance testing machine, including a supporting base plate 1 and a supporting folding plate 2 fixedly installed on the supporting base plate 1. An electric push rod 3 is fixedly installed on the supporting folding plate 2, and a connecting plate 8 is fixedly installed at the output end of the electric push rod 3. A connecting seat 14 is rotatably arranged on the connecting plate 8, and a driving component for driving the connecting seat 14 to rotate is provided on the connecting plate 8. A friction ring plate 19 is detachably installed on the connecting seat 14, and a locking component for installing the friction ring plate 19 on the connecting seat 14 is provided. By providing the locking component, pulling the connecting plate 21 causes the sliding insert plate 17 to move out of the locking groove 22, releasing the restriction on the arc-shaped limiting plate 18. The friction ring plate 19 can be disassembled and replaced. The disassembly and installation of the friction ring plate 19 can be quickly completed without the aid of external tools, which significantly improves the ease of operation and testing efficiency of the equipment and has strong practicality.
[0020] like Figure 3 and Figure 4 As shown, the locking assembly includes a sliding strip 15 that slides into the connecting seat 14. One end of the sliding strip 15 is fixedly connected to a connecting plate 21. A moving groove 16 is provided in the connecting seat 14, and a sliding insert plate 17 is slidably connected in the moving groove 16. The sliding strip 15 and the sliding insert plate 17 are fixedly connected. A return spring 20 is sleeved on the sliding strip 15. One end of the return spring 20 is fixedly connected to the connecting plate 21, and the other end of the return spring 20 is fixedly connected to the connecting seat 14. An arc-shaped limiting plate 18 is fixedly installed on the friction ring plate 19. The arc-shaped limiting plate 18 has a locking groove 22 for the sliding insert plate 17 to extend into. The connecting seat 14 has a limiting groove 22 for the arc-shaped limiting plate 18 to extend into. 3. By pulling the connecting plate 21, the connecting plate 21 moves the sliding insert plate 17 out of the locking groove 22, releasing the restriction on the arc-shaped limiting plate 18, allowing the friction ring plate 19 to be disassembled and replaced; when installing the friction ring plate 19, pulling the connecting plate 21 causes the sliding insert plate 17 to move in the moving groove 16 via the sliding bar 15, stretching the return spring 20. By inserting the arc-shaped limiting plate 18 into the limiting groove 23, the connecting plate 21 is released. Under the elastic action of the return spring 20, the connecting plate 21 is reset, which in turn causes the sliding bar 15 to reset. The sliding bar 15 then causes the sliding insert plate 17 to extend into the locking groove 22, locking the arc-shaped limiting plate 18 in the limiting groove 23.
[0021] like Figure 1 and Figure 4 As shown, the drive assembly includes a rotating column 11 rotatably mounted on a connecting plate 8, a second gear 12 fixedly mounted on the rotating column 11, a motor 9 fixedly mounted on the connecting plate 8, a first gear 10 fixedly mounted at the output end of the motor 9, the first gear 10 meshing with the second gear 12, the lower end of the rotating column 11 fixedly connected to a connecting seat 14, a supporting chassis 4 provided on a supporting base plate 1, multiple electric telescopic rods 5 provided on the supporting chassis 4, a push plate 6 fixedly connected to the output end of the electric telescopic rods 5, a clutch plate 7 placed on the supporting chassis 4, the multiple electric telescopic rods 5 driving the push plate 6 to fix the clutch plate 7 on the supporting chassis 4, the electric push rod 3 driving the connecting seat 14 to move, so that the friction ring plate 19 contacts the clutch plate 7, the motor 9 is started, the motor 9 drives the first gear 10 to rotate, the first gear 10 drives the second gear 12 to rotate, and then drives the rotating column 11 to rotate on the connecting plate 8, so that the friction ring plate 19 rotates and rubs on the clutch plate 7, and the friction performance of the clutch plate 7 is tested.
[0022] In use, the clutch plate 7 is placed on the support chassis 4. Multiple electric telescopic rods 5 drive the push plate 6 to fix the clutch plate 7 on the support chassis 4. The electric push rod 3 drives the connecting seat 14 to move, so that the friction ring plate 19 contacts the clutch plate 7. The motor 9 is started, and the motor 9 drives the first gear 10 to rotate. The first gear 10 drives the second gear 12 to rotate, which in turn drives the rotating column 11 to rotate on the connecting plate 8, so that the friction ring plate 19 rotates and rubs on the clutch plate 7, and the friction performance of the clutch plate 7 is tested. When the friction ring plate 19 needs to be replaced, by pulling the connecting plate 21, the connecting plate 21 moves the sliding insert plate 17 out of the locking groove 22 via the sliding bar 15, releasing the restriction on the arc-shaped limiting plate 18, and the friction ring plate 19 can be disassembled and replaced. When installing the friction ring plate 19, by pulling the connecting plate 21, the connecting plate 21 moves the sliding insert plate 17 in the moving groove 16 via the sliding bar 15, and the return spring 20 is stretched. By inserting the arc-shaped limiting plate 18 into the limiting groove 23, the connecting plate 21 is released. Under the elastic action of the return spring 20, the connecting plate 21 is reset, which in turn drives the sliding bar 15 to reset. The sliding bar 15 drives the sliding insert plate 17 into the locking groove 22, locking the arc-shaped limiting plate 18 in the limiting groove 23, and completing the installation.
