[0019] The positioning and clamping mechanism includes a rotating table 2 connected to the workbench 1 for forward and backward movement, a first driving mechanism 3 that drives the rotating table 2 to move, a pressure ring mechanism and a center positioning shaft 4 arranged on the rotating table 2, a screw hole is arranged in the middle of the top of the rotating table 2, the outer diameter of the center positioning shaft 4 corresponds to the inner diameter of the inner hole of the clutch plate 5 to be punched, a connecting column 6 is arranged at the bottom end of the center positioning shaft 4, the connecting column 6 is screwed in the screw hole, and multiple clutch plates 5 are stacked and sleeved on the center positioning shaft 4, a first pressure ring 7 is also fixed to the upper end of the center positioning shaft 4, the first pressure ring 7 is abutted against the inner periphery of the clutch plate 5 located at the top, an annular bracket 8 is also arranged on the top of the rotating table 2, a second pressure ring 9 is connected to the bottom of the bracket 8 for lifting and lowering, and a second driving mechanism 10 that drives the second pressure ring 9 to lift and lower is also arranged on the bracket 8, and the second pressure ring 9 is abutted against the outer periphery of the clutch plate 5 located at the top after being lowered, and the area between the first pressure ring 7 and the second pressure ring 9 forms a punching area.

[0020] The working principle of the above structure is as follows: the staff places the multi-plate clutch plates 5 on the rotating table 2 from one side of the bracket 8, and after they are neatly stacked, the central positioning shaft 4 is passed through the inner holes of each clutch plate 5 and screwed to the rotating table 2 from the top of the bracket 8. The fixing process of the central positioning shaft 4 also plays a role in further calibrating and positioning each clutch plate 5; finally, the first pressure ring 7 is fixed on the central shaft, and the first pressure ring 7 is abutted against the inner periphery of the clutch plate 5 at the top; after the central positioning shaft 4 and the first pressure ring 7 are fixed, the second driving mechanism 10 is started so that the second pressure ring 9 is lowered and abuts against the outer periphery of the clutch plate 5 located at the top; at this time, each clutch plate 5 is limited by the central axis, the first pressure ring 7 and the second pressure ring 9 and cannot be displaced, and the punching mechanism is lowered to punch holes in the clutch plate 5; after punching a hole, the rotating table 2 rotates a certain angle and then punches the next hole; after punching a circle of holes on the clutch plate 5, the rotating table 2 moves forward or backward, and the above actions are repeated until two or more circles of holes are punched on the clutch plate 5, and the processing is completed; after the processing is completed, the staff removes the central axis and then takes out the clutch plate 5 from one side of the bracket 8.

[0021] The beneficial effects of the above structure are: the structure is simple, and multiple clutch plates 5 can be punched at the same time. Each clutch plate 5 is accurately positioned and is not easily displaced after positioning, thereby ensuring the accuracy of the punching position.
