[0008] One side of the four-axis turntable is rotatably connected with a turntable. On the side of the four-axis turntable opposite to the turntable, there is a cylinder fixing seat, and a cylinder is fixed inside the cylinder fixing seat.

[0009] The center of the side of the turntable of the four-axis turntable away from the four-axis turntable is connected with a product shaft. A CAM groove product is sleeved on the product shaft. A tension block is arranged at one end of the product shaft away from the four-axis turntable, and a pressing plate is arranged outside the tension block.

[0010] The product shaft is concentric with the cylinder fixing seat and the cylinder.

[0011] A connecting shaft is slidably connected to the center of the four-axis turntable. The connecting shaft is slidably connected with the product shaft. Both ends of the connecting shaft expose the cylinder fixing seat and the product shaft. One end of the connecting shaft exposing the cylinder fixing seat is connected with the cylinder piston rod, and one end of the connecting shaft exposing the product shaft is connected with the tension block.

[0012] Further, the product shaft is fixed to the center of the turntable of the four-axis turntable by screws.

[0013] Further, the cylinder is fixed to the cylinder fixing seat by screws.

[0014] Further, the tension block is detachably connected to the connecting shaft.

[0015] Furthermore, there are at least two tensioning blocks, and the tensioning blocks are evenly distributed on the outside of the connecting shaft.

[0016] 3. Beneficial Effects

[0017] The advantages of the utility model compared with the prior art are:

[0018] Use the cylinder to pull the connecting shaft, and the connecting shaft pulls the tension block to make the fan-shaped part at the front end of the positioning shaft open and tighten the pressure plate. The pressure plate presses the product to achieve stable clamping force, less deformation during processing, increased production capacity, reduced defective risks, and easy operation.
