[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Please see Figure 1-6 As shown in the figure, an end face polishing device for processing an electromagnetic clutch according to an embodiment of the present invention includes a base 1, a body 10 disposed on the upper surface of the base 1, and a polishing unit 11 disposed on the body 10. The body 10 is provided with an operating table 2 at the corresponding position of the polishing unit 11, and the operating table 2 has a accommodating cavity 20 formed therein. Two positioning grooves 21 are symmetrically opened on the upper surface of the operating table 2, and two clamping plates 22 are slidably disposed in the positioning grooves 21. The accommodating cavity 20 is provided with an operating mechanism for controlling the two clamping plates 22 to clamp or release the clutch workpiece.
[0023] When in use, place the clutch workpiece to be processed in the center of the upper surface of the operating table 2. Control the two clamping plates 22 to move towards each other through the operating mechanism to clamp and limit the clutch workpiece. Then, the machine body 10 controls the polishing unit 11 to polish the fixed clutch workpiece. After polishing, release the clamping of the clutch workpiece, and then remove it and replace the next clutch workpiece to be processed.
[0024] This utility model, by setting up an operating mechanism, controls the two clamping plates 22 to quickly clamp or release the clutch workpiece, making the operation convenient and quick, and effectively improving the working efficiency and overall practicality of the equipment.
[0025] The clamping plate 22 has a V-shaped structure and is connected to a sliding column 23 that is adapted to the positioning groove 21.
[0026] When in use, the clamping plate 22 has a V-shaped structure, which allows it to adapt to the clamping limit of clutch workpieces of different sizes, improving the flexibility of the equipment.
[0027] The sliding column 23 and the positioning groove 21 are in sliding engagement. Specifically, the outer ring of the sliding column 23 is fitted with a limiting piece, and the inner side wall of the positioning groove 21 is formed with a limiting groove that matches the limiting piece. The sliding engagement between the limiting piece and the limiting groove limits the movement path of the sliding column 23.
[0028] The operating mechanism includes a pivot 3 rotatably disposed in the accommodating cavity 20, a transmission disk 30 disposed on the outside of the pivot 3, and two arc-shaped track grooves 31 correspondingly formed on the top surface of the transmission disk 30, and the lower ends of the two sliding columns 23 extending into the track grooves 31 and slidingly engaging with the track grooves 31.
[0029] When using, please refer to the instruction manual attached. Figure 5 The control pivot 3 drives the transmission disc 30 to rotate in the forward or reverse direction. The rotation of the transmission disc 30, through the sliding engagement between the two track grooves 31 and the slider 52, and the sliding engagement between the slide column 23 and the positioning groove 21, drives the two clamping plates 22 to move towards or away from each other, so as to achieve clamping or releasing of the clutch workpiece.
[0030] Two support seats are provided on the inner wall of the accommodating cavity 20 at the corresponding position of the transmission disk 30. The two support seats are used to provide support for the support seats, ensuring smooth rotation while preventing deviation during rotation.
[0031] A gear 32 is fixedly sleeved on the outer surface of the pivot 3. A guide post 4 is fixedly sleeved on the inner wall of the accommodating cavity 20. A toothed plate 40 that meshes with the gear 32 is slidably sleeved on one end of the guide post 4. A push rod 41 is provided at the end of the toothed plate 40 away from the guide post 4. The push rod 41 extends through to the outside of the operating table 2 and is connected to the push plate 42. The guide post 4 is a quadrangular prism and a limiting ring 43 is fixedly sleeved on its outer ring. A guide channel 44 that matches the guide post 4 is formed at one end of the toothed plate 40. A first spring 45 is sleeved on the outer ring of the guide post 4 between the limiting ring 43 and the toothed plate 40.
[0032] In use, the movement of the toothed plate 40 is controlled by the push rod 41, and the movement path of the toothed plate 40 is limited by the cooperation between the guide post 4 and the guide channel 44. The toothed plate 40 and the gear 32 are meshed. The forward or reverse rotation of the pivot 3 and the transmission disk 30 can be controlled by pushing or pulling the toothed plate 40 inward by the push rod 41.
[0033] Specifically, the push rod 41 pushes inward to drive the toothed plate 40 to slide against the force of the first spring 45. The toothed plate 40 drives the pivot 3 and the transmission disk 30 to rotate counterclockwise. At this time, the transmission disk 30 drives the two clamping plates 22 to move in opposite directions, placing the clutch workpiece to be processed in the center of the top surface of the operating table 2. At this time, the push rod 41 is released, and the toothed plate 40 retracts towards the initial position due to the release of the stored energy of the first spring 45, until the two clamping plates 22 clamp the clutch workpiece.
[0034] The guide post 4 is preferably a quadrangular prism to prevent the toothed plate 40 from rotating incorrectly during sliding. In actual use, pentagonal prisms, hexagonal prisms, etc. can also be used.
[0035] A locking seat 5 is fixedly installed at the front end of the operating table 2 on one side of the through hole of the push rod 41. The front end of the locking seat 5 is formed with a movable groove 50 and a slide rod 51 is fixedly installed in the movable groove 50. A slider 52 and a second spring 53 are sleeved on the slide rod 51. A locking block 54 is connected to the outer end of the slider 52. Several locking grooves 55 that are adapted to the locking block 54 are equidistantly and arrayed on the upper surface of the push rod 41. A first inclined waist 56 is formed on the side of the locking groove 55 near the operating table 2. A second inclined waist 57 is formed at the contact end of the locking block 54 and the locking groove 55.
[0036] During use, the slider 52 is locked to one of the locking grooves 55 by the force of the second spring 53. In the locked state, the push rod 41 can only be pulled outward and not pushed inward. Therefore, the push rod 41 only needs to be pulled outward until the two clamping plates 22 clamp the clutch workpiece. At this time, the push rod 41 cannot be pulled outward anymore, and it cannot be pushed inward due to the cooperation between the locking block 54 and the locking groove 55. This completes the clamping limit of the clutch workpiece. During the processing, the locking block 54 locks the push rod 41, causing the clamping plates 22 to achieve a stable clamping of the clutch workpiece.
[0037] One side of the locking block 54 has a force block formed. After processing, the force block drives the locking block 54 to slide upward along the slide rod 51 and disengage from the locking groove 55. At this time, the push rod 41 can control the push rod 41 to push inward, causing the two clamping plates 22 to release the clutch workpiece.
[0038] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
