[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] Reference Figure 1-Figure 3 As shown, the electromagnetic clutch end surface grinder of this embodiment includes a frame 1 and a grinding head 2 and a fixing mechanism 3 provided on the frame 1. The fixing mechanism 3 is used to grab the electromagnetic clutch. The fixing mechanism 3 is rotatably provided on the frame 1. The fixing mechanism 3 corresponds to the position of the grinding head 2. The fixing mechanism 3 includes:

[0021] A fixed seat 31, wherein the fixed seat 31 is rotatably arranged on the frame 1;

[0022] A fixing protrusion 32 is provided on the fixing seat 31 and extends toward one side of the grinding head 2;

[0023] A fixed electromagnet 33, which is fixed on the frame 1 and offset from the fixing seat 31;

[0024] The resisting spring 34 is disposed on the fixing seat 31 , and is disposed on a side facing the grinding head 2 .

[0025] Through the above technical solution, when using this equipment to process the electromagnetic clutch, the electromagnetic clutch is first placed on the fixed seat 31, and then the fixed electromagnet 33 is energized to complete the connection between the electromagnetic clutch and the fixed seat 31. At this time, the interference spring 34 is compressed. It should be noted that the fixed protrusion 32 is inserted into the through hole of the electromagnetic clutch, so that the axial position connection between the electromagnetic clutch and the fixed seat 31 is stable; then the processing is carried out, the fixed seat 31 rotates, and the grinding head 2 moves until it conflicts with the electromagnetic clutch, and then translates to complete the grinding of the electromagnetic clutch surface. The interference spring 34 directly conflicts with the electromagnetic clutch, and the fixed electromagnet 33 is attracted to grab it, avoiding the unevenness of the electromagnetic clutch during the placement process. In addition, the unevenness of the electromagnetic clutch surface is offset by over-squeezing the interference spring 34, so that the processing surface is in a flat state, thereby making the surface of the electromagnetic clutch flat after processing.

[0026] As an improved specific implementation, an adjustment protrusion 35 is provided on the fixing seat 31 , and the adjustment protrusion 35 is arranged toward the side of the grinding head 2 . The adjustment protrusion 35 is threadedly connected to the fixing seat 31 , and the interference spring 34 is fixedly connected to the adjustment protrusion 35 .

[0027] Through the above technical solution, by rotating the adjustment protrusion 35, the distance between the interference spring 34 and the fixing seat 31 can be changed, thereby compensating for the elastic loss of the interference spring 34 and extending the service life of the equipment.

[0028] As an improved specific implementation, one end of the adjusting protrusion 35 penetrates the fixing seat 31 , and a driven groove 351 is provided at the end of the adjusting protrusion 35 that penetrates the fixing seat 31 .

[0029] Through the above technical solution, when the position of the adjusting protrusion 35 is changed, the adjusting protrusion 35 is driven to rotate by the driven groove 351 on the other side of the fixing seat 31, which is convenient for operation.

[0030] As an improved specific implementation, a positioning button 352 is provided on the adjusting protrusion 35 , and the positioning button 352 is located inside the resisting spring 34 , and the positioning button 352 extends toward the grinding head 2 .

[0031] Through the above technical solution, the positioning button 352 is arranged on the inner side of the resistance spring 34, so that the resistance spring 34 is stable in position when compressed, and can provide good support for the electromagnetic clutch.

[0032] Specifically, a contact plate is provided at the end of the contact spring 34 . The contact plate has a large contact area with the electromagnetic clutch. When the contact spring 34 is squeezed, the contact spring 34 is evenly stressed.

[0033] As an improved specific implementation, a positioning sleeve 353 is provided on the adjusting protrusion 35 , and the positioning sleeve 353 is arranged on the outside of the resisting spring 34 , and the positioning sleeve 353 extends toward the grinding head 2 .

[0034] Through the above technical solution, the positioning sleeve 353 is arranged on the outside of the resistance spring 34 and cooperates with the positioning button 352 to limit the position of the resistance spring 34, so that the resistance spring 34 is stable when compressed and can provide good support for the electromagnetic clutch.

[0035] As an improved specific implementation, an auxiliary rod 4 is provided on the frame 1 , and the auxiliary rod 4 and the grinding head 2 are located on the same side, and a ball 41 is provided at the end of the auxiliary rod 4 .

[0036] Through the above technical solution, the grinding head 2 moves toward the fixed seat 31, and when grinding the cross section of the electromagnetic clutch, the auxiliary rod 4 moves synchronously, and the ball 41 conflicts with the electromagnetic clutch, so that the position of the electromagnetic clutch is stable during the grinding process of the grinding head 2, avoiding the shaking of the electromagnetic clutch, improving the stability during use, and improving the flatness of the finished product.

[0037] The ball 41 is rotatably connected to the auxiliary rod 4, with low resistance and wear.

[0038] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
