Equipped with a second knob 22; during operation, the existing production tooling, in the process of clamping the wheel hub 27 in cooperation with the punching device, is unable to control the clamping force of the clamp, which is prone to damage to the wheel hub 27 due to excessive clamping force, resulting in poor protection of the tooling for the wheel hub 27. By placing the wheel hub 27 on the placement table 4, rotating the first knob 18, driving the first screw rod 17 to rotate, the first screw rod 17 drives the two first sliders 16 thereon to move synchronously relative to each other, the two first sliders 16 drive the two moving blocks 5 thereon to move synchronously relative to each other, the two moving blocks 5 drive the two clamping blocks 6 thereon to move synchronously relative to each other, and in the process of the clamping block 6 moving toward the wheel hub 27, the moving plate 9 on the clamping block 6 first contacts the wheel hub 27 , then the movable plate 9 is pushed into the plate groove 8 by the wheel hub 27, and the movable plate 9 drives the limit block 11 thereon to move horizontally, and the limit block 11 drives the first electrode piece 12 to move horizontally toward the second electrode piece 13. When the clamping plate 11 is in contact with the side wall of the wheel hub 27, the movable plate 9 is completely pushed into the plate groove 8. At this time, the first electrode piece 12 is in contact with the second electrode piece 13, so that the internal circuit of the indicator light 7 is connected, and the indicator light 7 is turned on, indicating that the clamping plate 11 is in contact with the side wall of the wheel hub 27; the two first sliders 16 drive the two clamping blocks 6 thereon to successively stick to the side wall of the wheel hub 27. When the indicator light 7 on the second clamping block 6 is turned on, stop turning the first knob 18. At this time, the clamping force of the two clamping blocks 6 on the wheel hub 27 is moderate;

[0020] Then, rotate the second knob 22 to drive the second screw rod 21 to rotate, and the second screw rod 21 drives the two second sliders 20 thereon to move synchronously relative to each other, and the two second sliders 20 drive the two moving blocks 5 thereon to move synchronously relative to each other, and the two moving blocks 5 drive the two clamping blocks 6 thereon to move synchronously relative to each other, and the two clamping blocks 6 repeat the above steps.

At this time, the clamping force of the two clamping blocks 6 on the wheel hub 27 is moderate; this structure can accurately adjust the clamping force to avoid damage to the wheel hub 27 caused by excessive clamping force, which is beneficial to improve the protection of the tooling to the wheel hub 27.

[0021] See also Figure 5 As shown, a rotating shaft 23 is rotatably installed inside the base 2, and the rotating shaft 23 is fixedly connected to the placement table 4. A first gear 24 is fixedly sleeved on the outer periphery of the rotating shaft 23. A motor 25 is installed inside the base 2, and the motor 25 is connected to the control panel 3 through an internal circuit. A second gear 26 is installed on the output shaft of the motor 25, and the second gear 26 is meshed with the first gear 24. During operation, the existing production tooling cooperates with the punching device to clamp the wheel hub 27. Since the fixture structure of the tooling is a fixed structure, the clamped wheel hub 27 cannot be rotated and adjusted, resulting in poor practicality of the tooling. The control system inside the control panel 3 controls the operation of the motor 25, and the motor 25 drives the second gear 26 to rotate. The second gear 26 drives the first gear 24 to rotate. The first gear 24 drives the rotating shaft 23 to rotate. The rotating shaft 23 drives the placement table 4 to rotate, and the placement table 4 drives the wheel hub 27 clamped thereon to rotate. The punching device can cooperate with the wheel hub 27 to perform efficient and continuous punching, which is beneficial to improving the practicality of the tooling.

[0022] Working principle: in the process of clamping the wheel hub 27 with the punching device, the existing production tooling cannot control the clamping force of the clamp, which is easy to cause damage to the wheel hub 27 due to excessive clamping force, resulting in poor protection of the tooling for the wheel hub 27. By placing the wheel hub 27 on the placement table 4, turning the first knob 18, driving the first screw rod 17 to rotate, the first screw rod 17 drives the two first sliders 16 thereon to move synchronously relative to each other, the two first sliders 16 drive the two moving blocks 5 thereon to move synchronously relative to each other, the two moving blocks 5 drive the two clamping blocks 6 thereon to move synchronously relative to each other, and in the process of the clamping block 6 moving toward the wheel hub 27, the moving plate 9 on the clamping block 6 first contacts the wheel hub 27, and the first slider 16 drives the two moving blocks 5 thereon to move synchronously relative to each other. The hub 27 contacts, and then the moving plate 9 is pushed into the plate groove 8 by the wheel hub 27. The moving plate 9 drives the limit block 11 thereon to move horizontally, and the limit block 11 drives the first electrode piece 12 to move horizontally toward the second electrode piece 13. When the clamping plate 11 is in contact with the side wall of the hub 27, the moving plate 9 is completely pushed into the plate groove 8. At this time, the first electrode piece 12 is in contact with the second electrode piece 13, so that the internal circuit of the indicator light 7 is connected, and the indicator light 7 is turned on, indicating that the clamping plate 11 is in contact with the side wall of the hub 27; the two first sliders 16 drive the two clamping blocks 6 thereon to successively stick to the side wall of the hub 27. When the indicator light 7 on the second clamping block 6 is turned on, stop turning the first knob 18. When the second clamping blocks 6 have a moderate clamping force on the wheel hub 27, the second knob 22 is then turned to drive the second screw rod 21 to rotate, and the second screw rod 21 drives the two second sliders 20 thereon to move synchronously relative to each other, and the two second sliders 20 drive the two moving blocks 5 thereon to move synchronously relative to each other, and the two moving blocks 5 drive the two clamping blocks 6 thereon to move synchronously relative to each other, and the two clamping blocks 6 repeat the above steps. When the indicator light 7 on the second clamping block 6 is turned on, the second knob 22 is stopped from being turned. At this time, the clamping force of the two clamping blocks 6 on the wheel hub 27 is moderate. This structure can accurately adjust the clamping force to avoid damage to the wheel hub 27 caused by excessive clamping force, which is conducive to improving work efficiency. The protectiveness of the wheel hub 27 is enhanced; in the process of clamping the wheel hub 27 in cooperation with the punching device, the existing production tooling has a fixed fixture structure and cannot rotate and adjust the clamped wheel hub 27, resulting in poor practicality of the tooling. The control system inside the control panel 3 controls the operation of the motor 25, the motor 25 drives the second gear 26 to rotate, the second gear 26 drives the first gear 24 to rotate, the first gear 24 drives the rotating shaft 23 to rotate, the rotating shaft 23 drives the placement table 4 to rotate, and the placement table 4 drives the wheel hub 27 clamped thereon to rotate, and the punching device can be cooperated to perform efficient and continuous punching on the wheel hub 27, which is beneficial to improving the practicality of the tooling.
