Workpiece anti-deviation limiting mechanism for machining

The utility model discloses a workpiece anti-deviation limiting mechanism for machining, which belongs to the technical field of machining and comprises a U-shaped support and a reciprocating lead screw rotatably mounted in the support, a motor is mounted on the side face of the support, and an output shaft of the motor is fixedly connected with the reciprocating lead screw. According to the workpiece anti-deviation limiting mechanism used for machining, the clamping plates and the reciprocating lead screw are arranged, the position of the sliding base is adjusted through the effect that the motor drives the reciprocating lead screw to rotate, then the position of a workpiece is adjusted, and the threaded rod is installed on the fixing plate in a threaded mode, so that when the threaded rod is rotated, the clamping plates are driven to be close to the workpiece; the limiting effect is achieved while a workpiece is clamped and fixed, deviation of the workpiece is avoided, the moving distance between the two mo
