Lathe fixture for machining large-diameter thin-wall part

Abstract

The utility model belongs to the technical field of fixtures, and discloses a lathe fixture for processing large-diameter thin-wall parts, which comprises a base (1), a pressure plate (2), a connecting bolt (4), a compression bolt (3) and a nut (5), the base (1) is disc-shaped, and the bottom surface of the base (1) is connected with lathe equipment through a connecting bolt (4) and a nut (5); the pressure plate (2) is connected with the top surface of the base (1) through the compression bolt (3); the side face of the pressing disc (2) is arranged to be an inclined face matched with the inner wall of a to-be-machined part, and the to-be-machined part is clamped between the top face of the base (1) and the bottom face of the pressing disc (2). The clamping device is simple in structure and convenient to install and detach, pressing force borne by a workpiece can be evenly distributed through the clamping mode, and the problem that the workpiece deforms due to stress in conventional clamping is solved.
