The positioning mechanism is a central positioning circular truncated cone 2, the outer diameter of the central positioning circular truncated cone 2 is matched with the inner diameter of the workpiece 3, when the positioning mechanism is used, the inner diameter of a traction pin disc to be machined is embedded into the central positioning circular truncated cone 2, the positioning function is achieved, and the workpiece 3 cannot move in the X-axis direction and the Y-axis direction.

The limiting mechanism is a corner oil cylinder, the corner oil cylinder comprises an oil cylinder and a pressing plate, and the pressing plate is driven by the oil cylinder to rotate and lift. It can be understood that the corner oil cylinder is hydraulically driven, can be automatically compressed, and does not need to manually adjust the pressing plate.
