Description

Technical Field

[0001] This utility model relates to the technical field of clutch disc testing, specifically a clutch disc performance testing device. Background Technology

[0002] Clutch discs are composite materials whose primary function is friction, while also requiring structural performance. Automotive friction materials are mainly used to manufacture brake friction pads and clutch discs. A search revealed patent CN213516337U, which discloses a clutch disc performance testing device. This device includes a base and a collection chamber. A cylinder is mounted on one side of the base, and a drive motor is connected to the front end of the cylinder. A positioning rod is located at the front end of the drive motor, and a limit block is fixed to the outer wall of the positioning rod. A heating wire is installed on the outer wall of the limit block. A fixing block is connected to the front end of the positioning rod. A connecting rod is located below the drive motor, and a slider is fixed to one side of the connecting rod. A sliding groove is connected to one side of the slider, and a measuring block is located on one side of the sliding groove. A movable block is located inside the measuring block, and a scale is fixed to one side of the movable block. A mounting base is fixed to the other side of the base. When the cylinder of this clutch disc performance testing device is activated, it drives the drive motor, thereby moving the clutch disc and allowing it to be moved into the testing chamber. This eliminates the need for manual operation, making it convenient for users. However, during the wear resistance test of the clutch disc, the cylinder pushes the rotating device to move the clutch disc into the interior of the friction device. During the friction process, the surface of the clutch disc becomes uneven due to wear. As the wear resistance test continues, the unevenness of the surface will cause the device holding the clutch disc to vibrate, and in severe cases, the clamping device may loosen, causing the clutch position to wobble. At the same time, the device can only collect the friction debris and cannot detect the changes in the surface after friction, thus reducing the efficiency of the device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a clutch disc performance testing device. This device solves the problem that during wear resistance testing of clutch discs, a cylinder drives a rotating device to move the clutch disc into the friction device. During friction, the surface of the clutch disc becomes uneven due to wear, causing vibrations in the device holding the clutch disc during further wear resistance testing. In severe cases, this can lead to loosening of the clamping device and displacement of the clutch. Furthermore, the device can only collect friction debris and cannot detect changes in the surface after friction, thus reducing its efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a clutch plate performance testing device, comprising a base, a lifting platform, and a friction plate.

A rotary motor is fixedly installed on the bottom surface of the lifting platform, and the rotary motor is slidably connected inside the base. A third support frame, which is U-shaped, is fixedly installed on the upper end of the base. A second cylinder is symmetrically fixedly installed at one end. The output shaft of the second cylinder passes through the interior of a third support frame. A connecting seat is provided at the lower end of the third support frame. Both sides of the bottom surface of the connecting seat are fixedly connected to the output shaft of the second cylinder. A rotating plate is rotatably connected to the bottom surface of the connecting seat. Both the rotating plate and the connecting seat are annular and are fitted onto the wall of the mounting rod. A mounting plate is fixedly installed on the right side of the top surface of the base. A first cylinder is fixedly installed on the right side wall of the mounting plate. The output shaft of the first cylinder passes through the interior of the mounting plate and is fixedly connected to a friction plate.

[0006] Preferably, a first support frame is fixedly installed on the upper end of the base. The first support frame is U-shaped, and a reciprocating motor is symmetrically fixedly installed on the top surface of the first support frame.

The second support frame is U-shaped, and a sliding rod is symmetrically fixedly installed between the top of the second support frame and the base. The two ends of the lifting platform are respectively slidably sleeved on the wall of the sliding rod, thereby strengthening the support of the lifting platform.

[0008] Preferably, the bottom surface of the scale rod is rotatably connected with ball bearings, which allows the scale rod to roll easily on the clutch disc and prevents the scale rod from moving with the rotation of the clutch disc, thus preventing damage to the scale rod.

[0009] This invention provides a clutch disc performance testing device. It has the following advantages:

[0010] 1.

The lifting platform 2 is placed on the top surface of the base 1. A rotating seat 3 is rotatably connected inside the top surface of the lifting platform 2.

A second cylinder 13 is symmetrically fixedly installed on the upper end of the third support frame 12. The output shaft of the second cylinder 13 passes through the inside of the third support frame 12. A connecting seat 14 is provided at the lower end of the third support frame 12. Both sides of the bottom surface of the connecting seat 14 are fixedly connected to the output shaft of the second cylinder 13. A rotating plate 19 is rotatably connected to the bottom surface of the connecting seat 14. Both the connecting seat 14 and the mounting plate 18 are annular and are fitted onto the wall of the mounting rod 18. The mounting plate 25 is fixedly installed on the right side of the top surface of the base 1. The first cylinder 11 is fixedly installed on the right side wall of the mounting plate 25. The output shaft of the first cylinder 11 is fixedly connected to the friction plate 9 through the interior of the mounting plate 25. When the clutch disc is tested for wear resistance, the clutch disc is fitted onto the wall of the mounting plate 18 and placed on the heating boss 4. Then the second cylinder 13 is opened, so that the connecting seat 14 drives the rotating plate 19 to fit onto the wall of the mounting rod 18 and presses the placed clutch disc so that it can be clamped by the heating boss 4. After the position is stable, the first cylinder 11 is opened, so that the friction plate 9 moves above the heating boss 4 and the friction plate 9 is in contact with the side wall of the clutch disc. Then the rotary motor 24 is turned on, so that the rotating seat 3 rotates and is rubbed by the friction plate 9.

[0021] Example 2

[0022] In this embodiment, as Figure 1-5As shown, multiple fixed tubes 17 are provided above the heating boss 4. A moving rod 15 is slidably connected to the upper end of the third support frame 12. A connecting plate 16 is fixedly connected to the lower end of the moving rod 15. The upper ends of the fixed tubes 17 are all fixedly connected to the bottom surface of the connecting plate 16. A sliding column 21 is slidably connected inside the fixed tube 17. A tension spring 20 is fixedly installed between the top surface of the sliding column 21 and the upper side wall inside the fixed tube 17. A scale rod 22 is fixedly installed on the bottom surface of the sliding column 21. A ball bearing 23 is rotatably connected inside the bottom surface of the scale rod 22. While grinding the clutch plate, the lower end of the scale rod 22 is made to fit against the top surface of the clutch plate, and can slide on the top surface of the clutch plate through the ball bearing 23. Not only can the friction condition of the clutch plate surface be observed according to the frequency of the scale rod 22 vibration, but the unevenness of the clutch plate surface after the friction is completed can also be observed through the scale.

[0023] Example 3

[0024] In this embodiment, as Figure 1-5 As shown, a first support frame 5 is fixedly installed on the upper end of the base 1. The first support frame 5 is U-shaped. A reciprocating motor 7 is symmetrically fixedly installed on the top surface of the first support frame 5.

The two ends of the lifting platform 2 are respectively slidably sleeved onto the rod wall of the slide rod 10. While grinding the clutch plate, the reciprocating motor 7 is turned on according to the grinding position, so that the screw 6 rotates and drives the lifting platform 2 to move up and down, adjusting the distance between the clutch plate and the friction plate 9, so that the grinding work can be carried out conveniently.

[0025] It should be noted that, in this embodiment, when using the clutch disc performance testing device, such as Figure 1-5As shown, during the wear resistance test of the clutch disc, the clutch disc is fitted onto the rod wall of the mounting plate 18 and placed on the heating boss 4. Then, the second cylinder 13 is opened, causing the connecting seat 14 to drive the rotating plate 19 to fit onto the rod wall of the mounting rod 18, pressing the placed clutch disc so that it can be clamped by the heating boss 4. After the position is stable, the reciprocating motor 7 is turned on according to the grinding position, causing the screw 6 to rotate and drive the lifting platform 2 to move up and down, adjusting the distance between the clutch disc and the friction plate 9 to facilitate grinding. The first cylinder 11 is then opened, causing the friction plate 9 to move to the heating boss. Above platform 4, the friction plate 9 is brought into contact with the side wall of the clutch disc. Then, the rotary motor 24 is turned on, causing the rotating seat 3 to rotate and rub against it through the friction plate 9. At the same time, the heating boss 4 heats the clutch disc, simulating the stability experienced by the clutch disc during normal operation. While polishing the clutch disc, the lower end of the scale rod 22 is brought into contact with the top surface of the clutch disc, and it can slide on the top surface of the clutch disc through the ball bearing 23. Not only can the friction condition of the clutch disc surface be observed according to the frequency of the scale rod 22's vibration, but the unevenness of the clutch disc surface after the friction is completed can also be observed through the scale.
