Detailed Description
Embodiments of the present invention will be described with reference to the accompanying drawings, and it should be understood that the embodiments described herein are merely illustrative and explanatory of the present invention, and are not restrictive of the invention.
As shown in fig. 1 to 3, the present invention discloses a jaw device 100, which comprises a jaw 1, a column 2, a driving component 3, a connecting flange 4 and a trolley 5; the clamping jaws are arranged on one surface of the upright post, the upper part and the lower part of the upright post are respectively provided with a driving component, the connecting flange is arranged on the other surface of the upright post, and the two driving components drive the upper clamping jaw and the lower clamping jaw to be separated or folded; the device is conveniently arranged in front of a hydraulic oil cylinder in the withdrawal machine; the upright post 2 is arranged on the trolley 5;
the jaw 1 is provided with an upper half part and a lower half part (11, 12) and is formed by combining two concave body notches in an up-and-down opposite direction, and the outer opening of the jaw is provided with a convex edge 13 matched with the back pressure groove; when the upper and lower two half claws are closed, the convex edges are just clamped into the back pressure groove of the wheel set hub, and the dismounting and back pressure work can be completed according to the requirement;
the upright post 2 is concave and is erected on the side; the upper and lower two half claws are arranged on one surface of the side vertical groove;
the driving assembly 3 consists of a hydraulic motor, a large gear, a small gear and a screw rod, wherein the large gear 32 is arranged in front of the hydraulic motor 31, the small gear 33 is arranged at one end of the screw rod 34, the large gear and the small gear work in a matching way, and the other end of the screw rod is arranged in a clamping jaw;
