[0007] Furthermore, fixing seats are fixedly installed on the front side, rear side, left side and right side of the bottom plate respectively, and the horizontal positioning seats and the pressing mechanisms are fixedly installed on the corresponding fixing seats.

[0009] Further, the pressing mechanisms on the left and right sides are lever oil cylinders, and the pressing plates of the lever oil cylinders point to the corresponding horizontal positioning seats.

[0010] Further, the side pushing mechanism includes a bracket fixedly installed on the bottom plate, a push plate that is hinged and rotates up and down on the bracket, and a setscrew installed on the bracket on the side away from the circumferential positioning seat through threads.

[0011] Further, on the bottom plate, guide plates that are radially opposite are fixedly installed on both sides of the chuck. When placing, they guide the rail vehicle traction body, facilitating the rapid positioning of the rail vehicle traction body.

[0012] The beneficial effects of the present utility model are as follows:

[0013] Since a vertical chuck is fixedly installed at the center of the bottom plate, horizontal positioning seats are fixedly installed on the front side, rear side, left side, and right side of the chuck on the bottom plate, and pressing mechanisms are fixedly installed on the outside of the four horizontal positioning seats on the bottom plate. The action ends of the pressing mechanisms point to the corresponding horizontal positioning seats; a circumferential positioning seat is fixedly installed between the chuck and the horizontal positioning seat on the rear side of the bottom plate, and a side pushing mechanism is fixedly installed on one side of the circumferential positioning seat on the bottom plate. The action end of the side pushing mechanism points to the circumferential positioning seat. The rail vehicle traction body is pressed down on the upper end surface of the horizontal positioning seat through the pressing mechanism for up and down positioning, the center of the rail vehicle traction body is clamped by the jaws of the chuck, and the rail vehicle traction body is abutted against the side surface of the circumferential positioning seat through the side pushing mechanism for circumferential positioning. The positioning operation is simple, time-saving and labor-saving, the positioning efficiency is high, and the positioning structure is firm, the processing is precise, and the product qualification rate is high.
