Description

Technical Field

[0001] The invention belongs to the technical field of friction plate detection, and in particular relates to a friction plate running-in device. Background Art

[0002] When testing the wear resistance of friction plates, the current industry-wide solution relies heavily on manual installation and removal. Specifically, testers manually secure the friction plates to the testing equipment and then manually remove them after the friction performance test is complete. However, this traditional manual operation has numerous drawbacks. Firstly, manual clamping makes it difficult to ensure the stability of the friction plate installation, potentially causing displacement or loosening during testing, affecting the accuracy of the test results. Secondly, the surface temperature of the friction plate rises significantly after the friction test, making manual removal and removal highly susceptible to burns, posing a serious safety hazard.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Depend on Figure 1-7 The present invention discloses a friction plate running-in device, comprising a device body 1, a support frame 2 being fixedly connected to the upper end of the device body 1, a rotatable grinding piece 3 being further provided at the upper end of the device body 1, an outer cover 4 being movable up and down being provided above the grinding piece 3, a clamping piece 10 being provided inside the outer cover 4, the clamping piece 10 being a shell structure with an opening downward, a retractable wedge 11 being provided inside the clamping piece 10, the friction plate being able to enter the clamping piece 10, and when the friction plate enters the clamping piece 10, the wedge 11 being able to be pushed, and then the friction plate being able to be fixed between the wedge 11 and the inner top wall of the clamping piece 10;

[0025] A rotating frame 6 is also provided above the equipment body 1. The rotating frame 6 is located on one side of the grinding piece 3. A rotating plate 7 is fixed to the upper end of the rotating frame 6. The rotating plate 7 is a strip structure. One end of the rotating plate 7 is the loading area, and the other end is the unloading area. When the rotating plate 7 rotates, the loading area and the unloading area can be respectively located below the outer cover 4. A boss 8 is provided in the loading area, and the friction plate is placed on the boss 8. When the friction plate is placed on the boss 8, the edge of the friction plate extends outside the boss 8. When the loading area is located below the outer cover 4, the friction plate can enter between the wedge 11 and the clamping member 10. A toggle rod 9 is provided in the unloading area. When the unloading area is located below the outer cover 4, the toggle rod 9 can cooperate with the wedge 11 to make the friction plate above the wedge 11 fall down.

[0026] Loading process: The user places the friction plate to be tested on the boss 8, and then the rotating frame 6 rotates so that the loading area is located below the outer cover 4, and then the outer cover 4 moves downward so that the clamping piece 10 can be put on the outside of the friction plate. The friction plate contacts the wedge block 11, so that the wedge block 11 is pushed to one side, and then the friction plate moves to the upper end of the wedge block 11. The wedge block 11 can be pressed against the bottom of the friction plate to prevent the friction plate from falling.

[0027] Testing process: The rotating frame 6 rotates to one side, the outer cover 4 continues to move downward and covers the outside of the grinding piece 3, and the upper end of the grinding piece 3 contacts the lower end of the friction plate, so that when the grinding piece 3 rotates, the friction plate performs friction testing.

[0028] Unloading process: After the test is completed, the outer cover 4 and the clamping member 10 move upward together, and then the rotating frame 6 rotates, so that the unloading area rotates to the bottom of the outer cover 4, and then the outer cover 4 moves downward, the clamping member 10 contacts the toggle rod 9, and then the wedge block 11 is pushed to one side, so that the friction plate after the test falls onto the unloading area, and then the rotating frame 6 rotates again to transfer the friction plate to one side of the outer cover 4.

[0029] When this device is implemented, it is convenient to load, test and unload the friction plate, and the entire process does not require workers to enter the work area, ensuring the safety of the operation. The use of the outer cover 4 can also prevent debris from flying out during the test.

[0030] The rotating frame 6 and the grinding member 3 are both driven by a motor. The grinding member 3 is in contact with the friction plate to rub against the friction plate, thereby testing the performance of the friction plate.

[0031] The friction plate in this application is a disc-shaped structure.

[0032] A fixing seat 12 is provided inside the clamping member 10, and a cavity 15 is provided at one end of the fixing seat 12. The wedge block 11 is located in the cavity 15, and the side of the wedge block 11 away from the fixing seat 12 is an inclined surface, and the inclined surface gradually extends from bottom to top in the direction away from the fixing seat 12. The upper end surface of the wedge block 11 is a plane, and the wedge block 11 and the fixing seat 12 are connected by a spring 16. A notch is provided on the other end of the fixing seat 12, and a pulling block 18 is provided in the notch. The pulling block 18 and the wedge block 11 are connected by a connecting rope 17. A slider 19 is fixed to the side of the pulling block 18, and a slide groove 20 is provided in the side wall of the notch. The slider 19 can slide in the slide groove 20 so that the pulling block 18 can pull the wedge block 11 into the cavity 15.

[0033] When the friction plate enters the clamping part 10, the edge of the friction plate contacts the inclined surface of the wedge block 11, thereby pushing the wedge block 11 to one side, and then the friction plate moves to the top of the wedge block 11. When the friction plate moves to the top of the wedge block 11, the spring 16 can push the wedge block 11 to reset, so that the upper end surface of the wedge block 11 is in contact with the friction plate to fix the position of the friction plate, thereby facilitating the loading step.

[0034] After the friction plate inspection is completed, the pulling block 18 is pulled toward one side so that the wedge block 11 is pulled into the cavity 15 , thereby causing the friction plate to fall.

[0035] The use of the spring 16 can reset the wedge 11 (to a state where the inclined surface is extended).

[0036] For the first embodiment of the falling of the friction plate, it has: the toggle rod 9 is an insertion rod 27, a vertical slot 26 is opened in the pulling block 18, the side wall of the slot 26 is provided with a first inclined surface, the lower end of the insertion rod 27 is fixedly connected to the unloading area, and the upper end of the insertion rod 27 is provided with a second inclined surface. When the fixed seat 12 drives the pulling block 18 to move downward and approach the unloading area, the first inclined surface can cooperate with the second inclined surface, so that the pulling block 18 pulls the wedge block 11 toward the inside of the fixed seat 12.

[0037] The second embodiment of the falling of the friction plate has: the toggle lever 9 is a second rack 30, a second rotatable gear 29 is provided in the fixed seat 12, and a third rack is provided at the lower end of the slider 19, the second gear 29 is engaged with the third rack, and the second gear 29 is engaged with the second rack 30, and the lower end of the second rack 30 is fixed to the unloading area. When the fixed seat 12 drives the pulling block 18 to move downward and approach the unloading area, the second rack 30 can cooperate with the second gear 29 to enable the pulling block 18 to pull the wedge block 11 toward the inside of the fixed seat 12.

[0038] A push rod 5 is also installed on the support frame 2. The push rod 5 passes through the outer cover 4 and is connected to the clamping member 10. A limit block is fixed to the outside of the push rod 5. The outer cover 4 is placed on the limit block, so that the outer cover 4 and the clamping member 10 can move up and down together. After the outer cover 4 is covered on the outside of the grinding member 3, the clamping member 10 can continue to move downward, so that the lower end of the friction plate contacts the upper end of the grinding member 10, thereby achieving the purpose of grinding detection.

[0039] In order to prevent the friction plate from rotating with the grinding piece 3 during detection, the following technical solution is provided: there are multiple fixed seats 12, and multiple fixed seats 12 are fixed to the fixing frame 13. The upper end of the fixing frame 13 is fixed with a ring block 21, and the ring block 21 is a hollow structure. The push rod 5 passes through the ring block 21 and is connected to the clamping member 10. A rotatable sleeve block 22 is provided on the clamping member 10, and the sleeve block 22 is sleeved outside the ring block 21. The sleeve block 22 and the ring block 21 are threadedly matched. A worm gear is provided outside the sleeve block 22, and a rotatable worm 23 is provided on one side of the sleeve block 22. The worm 23 cooperates with the worm gear, and a first gear 24 is fixed to one end of the worm 23. A first rack 25 is fixed to the outer cover 4, and the first rack 25 and the first gear 24 are meshed with each other.

[0040] When the outer cover 4 is covered on the outside of the grinding piece 3, the clamping piece 10 continues to move downward. At this time, the first rack 25 toggles the first gear 24. The rotation of the first gear 24 drives the worm 23 to rotate, and the worm 23 cooperates with the worm wheel on the surface of the sleeve block 22, thereby causing the sleeve block 22 to rotate. The sleeve block 22 and the ring block 21 are threadedly engaged, causing the ring block 21 to move upward. At this time, the upper end of the wedge block 11 pushes the friction plate into the clamping piece 10 to prevent the friction plate 10 from rotating with the grinding piece 3.

[0041] A gasket is also provided in the clamping member 10 to increase the friction between the friction plate and the clamping member 10, further ensuring the stability of the friction plate. The size of the grinding member 3 is smaller than that of the friction plate to prevent the grinding member 3 from contacting the wedge block 11.

[0042] The outer cover 4 is provided with a movable plate 14 that can move up and down. When the friction plate is loaded, in order to avoid the friction plate from being abutted against each other between the rotating frame 6 and the outer cover 4 and to prevent the friction plate from entering the clamping member 10, the movable plate 14 is provided.
