Semi-automatic clamping device for machining side face of presser foot motor bracket

The invention relates to the technical field of motors, and discloses a semi-automatic clamping device for a machining side face of a presser foot motor bracket. The semi-automatic clamping device comprises a base, wherein a rotary supporting block is fixedly connected to the right side of the upper surface of the base; a rotary handle is in threaded connection with the surface of the right side of the rotary supporting block; a connecting rod is rotatably connected to the surface of the right side of the rotary handle; bracket clamping mechanisms are arranged on the outer surface of the connecting rod; and a damping buffer mechanism is arranged on the lower surface of the base. According to the semi-automatic clamping device for the machining side face of the presser foot motor bracket, through rotation of the rotary handle, friction clamping plates on the opposite faces of two movable clamping plates perform forward motion and closing motion, so that the bracket can be fixed, and a situation that the bracke
