Abstract

This utility model relates to the field of machining fixture technology, specifically a self-centering rotary vise, comprising a base, a movable vise body, and a platform base. Two platform bases can slide synchronously and in the same direction on the base. A base synchronous sliding drive device is provided on the base. A movable vise body is rotatably mounted on each platform base. At least two pin holes A are evenly distributed on the platform base with the rotation center of the movable vise body as the center. The movable vise body is provided with pin holes B corresponding to pin holes A. Pins are installed in pin holes A and pin holes B. Clamping surfaces corresponding to the number of pin holes A are provided on the side of the movable vise body. The clamping surfaces of the two movable vises are used in pairs. This self-centering rotary vise has the technical advantages of efficient self-centering clamping, rapid indexing rotation, multi-type clamping adaptability, high precision and stability, low cost and easy maintenance.
