For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 , Figure 7As shown, a clutch plate grinding machine includes a frame 1. A bracket 2 is arranged on one side of the frame 1. A driving device 3 is arranged on the bracket 2. The driving device 3 is connected to a grinding wheel 4. The grinding wheel 4 has a built-in motor. The motor can drive the grinding wheel 4 to rotate, and the driving device 3 is used to drive the grinding wheel 4 to move in a three-dimensional space and is controlled by a numerical control program.

[0030] A turntable 5 is provided in the middle of the frame 1, a rotating shaft 6 is provided in the middle of the turntable 5, and the rotating shaft 6 is connected to a driving motor 7. The driving motor 7 is used to drive the turntable 5 to rotate. When the grinding wheel 4 moves above the clutch plate, the driving motor 7 works to rotate the turntable 5, and the grinding wheel 4 also rotates under the action of the motor, thereby grinding the clutch plate on the chassis.

[0031] The above are all conventional settings of the automatic grinder, which are prior art and will not be described in detail here.

[0032] Embodiment 1: Fixing device 8

[0033] like Figure 1-Figure 4 As shown, a fixing device 8 for fixing the clutch chassis is provided on the frame 1. The fixing device 8 comprises a fixing frame 9. The fixing frame 9 is fixedly connected to the driving device 3. A slide groove 10 is provided on one side of the fixing frame 9. A pressing rod 11 is slidably connected in the slide groove 10.

[0034] Correspondingly, a positioning seat 12 is provided on one side of the fixing frame 9 close to the pressing rod 11. A through slot 13 is provided in the middle of the positioning seat 12 for the pressing rod 11 to pass through. The positioning seat 12 is L-shaped, and a spring 14 is provided between the positioning seat 12 and the pressing rod 11.

[0035] Optimally, the bottom bearing of the pressing rod 11 is connected with a bottom plate 15. The area of ​​the bottom plate 15 is larger than the cross-sectional area of ​​the rotating shaft 6. The bottom plate 15 is used to prevent the clutch chassis from coming out.

[0036] Through the above arrangement, the pressing rod 11 can slide up and down on the fixing frame 9 , and after moving downward, the pressing rod 11 can be reset by the elastic force of the compressed spring 14 .

[0037] Optimally, a cylinder 16 is provided on the top of the motor connected to the grinding wheel 4. The cylinder 16 can drive the grinding wheel 4 to move in the longitudinal direction. A pressing plate 17 is fixedly connected to the top of the cylinder 16. The pressing plate 17 has a large area and covers the top of the pressing rod 11.

[0038] The clutch base to be polished and the clutch plate bolted to the clutch base are placed on the turntable 5. Afterwards, the grinding wheel 4 is driven to move to the edge of the turntable 5 by the driving device 3. Under the action of the cylinder 16, the grinding wheel 4 moves down to abut against the clutch plate. At this time, the driving motor 7 and the motor are turned on, so that the motor drives the grinding wheel 4 to rotate and polish the clutch plate. On the other hand, the driving motor 7 rotates to drive the turntable 5 to rotate, thereby causing the clutch plate to rotate, and the grinding wheel 4 can grind the edges of each clutch plate. In the above process, as the cylinder 16 moves down, the pressing plate 17 is driven to move down. When the pressing plate 17 moves down, the pressing plate 17 abuts against the top of the pressing rod 11, and drives the pressing rod 11 to move down. When the pressing rod 11 moves down, the spring 14 is compressed, and the pressing rod 11 is pressed down to make the bottom plate 15 abut against the top of the driving shaft 24 for limiting, to prevent the clutch chassis from being thrown out when the turntable 5 rotates.

[0039] After grinding is completed, the cylinder 16 drives the grinding wheel 4 to reset, and gradually steps from the edge to the direction of the rotating shaft 6 through the driving device 3, and finally all the clutch plates are ground.

[0040] Through the above arrangement, when the cylinder 16 drives the grinding wheel 4 to move downward, it can simultaneously drive the pressing rod 11 downward to limit the clutch chassis with the bottom plate 15. When the speed of the driving motor 7 is high, the clutch chassis will not fall off the rotating shaft 6, thereby reducing safety hazards.

[0041] Embodiment 2: Baffle device 18

[0042] like Figure 5 , Figure 6 As shown, a baffle device 18 is provided on the frame 1 for preventing sparks from flying when grinding. The baffle device 18 includes a frame 19 arranged around the bracket 2. A plurality of positioning posts 20 penetrating the frame 19 are provided at the edge of the frame 19. The bottom of the positioning posts 20 is fixedly connected to the frame 1. The frame 19 can slide up and down on the positioning posts 20. As described above, when the frame 19 moves up, it can cover the surrounding of the bracket 2, thereby preventing sparks from flying and reducing safety hazards.

[0043] Correspondingly, a transmission wheel 1 21 is provided on the rotating shaft 6. A transmission belt 22 is provided on the transmission wheel 1 21. A transmission wheel 23 is provided on one side of the transmission belt 22. When the rotating shaft 6 rotates, the transmission wheel 1 21 can be driven to rotate, and the power is transmitted to the transmission wheel 2 23 through the transmission belt 22, so that the transmission wheel 2 23 rotates.

[0044] A driving shaft 24 is fixedly penetrated in the middle of the transmission wheel 23. A bevel gear set 25 is connected to the top of the driving shaft 24. A driven shaft 26 is fixedly penetrated in the bevel gear set 25. The driven shaft 26 is connected to the frame 1 by a bearing. A gear 27 is fixedly sleeved on the driven shaft 26. A gear rod 28 is meshed on one side of the gear 27. The gear rod 28 is fixedly connected to the frame 19.

[0045] Optimally, a driving spring 29 is provided on the positioning column 20 between the frame 19 and the rack 1 .

[0046] As described above, when the clutch plate is being polished, the rotating shaft 6 rotates under the action of the driving motor 7, and drives the driving shaft 24 to rotate through the transmission wheel 1 21, the transmission belt 22, and the transmission wheel 2 23. The rotation of the driving shaft 24 drives the bevel gear set 25 to work, and then drives the driven shaft 26 to rotate. The driven shaft 26 drives the gear 27 to rotate, so that the gear rod 28 moves up. The gear rod 28 moves up and drives the frame 19 to move up, so that the clutch plate can be covered when the grinding wheel 4 is polishing to prevent sparks from flying.

[0047] As mentioned above, when the gear 27 rotates until the gear rod 28 moves up to the top, the frame 19 jumps under the action of the driving spring 29. Thus, the frame 19 is kept within a certain height range, achieving the purpose of controlling the position of the frame 19. After the processing and grinding work is completed, the driving motor 7 stops, and the staff manually presses the frame 19 to reset the frame 19 for subsequent new clutch plate grinding.

[0048] Through the above arrangement, sparks can be effectively avoided from flying during grinding work, thereby reducing safety hazards.

[0049] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
