[0024] As a technical optimization solution of the utility model, by setting a fixing mechanism 7, the sprocket can be fixed under the processing component 6, avoiding the position displacement of the sprocket when placed, causing the processed sprocket to fail to meet the quality requirements, and improving the processing efficiency of the sprocket.

[0025] refer to Figure 3 A friction pad 8 is fixedly connected to the inner side of the clamping block 79 , and the friction pad 8 is located on the top of the workbench 1 .

[0026] As a technical optimization solution of the utility model, by setting the friction pad 8, the friction force between the clamp block 79 and the contact surface of the sprocket can be increased, avoiding the small friction force between the clamp block 79 and the contact surface of the sprocket, causing the sprocket to shake during processing, and improving the fixing ability of the clamp block 79.

[0027] refer to Figure 4 The bottom of the rack 72 is slidably connected to a slide seat 9, and the bottom of the slide seat 9 is fixedly connected to the top of the workbench 1.

[0035] The working principle and use process of the utility model are as follows: when the sprocket needs to be clamped during use, the sprocket is first placed on the top of the placement plate 2, and then the second electric cylinder 71 is started. The second electric cylinder 71 drives the rack 72 to move to the left, and the rack 72 drives the driving gear 73 to rotate counterclockwise. The driving gear 73 drives the screw 75 to rotate counterclockwise, and the screw 75 drives the tooth plate 76 to move forward. The tooth plate 76 drives the transmission gear 77 to rotate, and the transmission gear 77 drives the clamping rod 78 to retract inward with the pin as the center. The clamping rod 78 and the clamping block 79 on the tooth plate 76 can clamp the sprocket. At this time, the sprocket is fixed directly below the processing component 6, thereby having the advantage of efficient positioning.
