The utility model provides a
brake drum gripper, which belongs to the technical field of
machining and
automation in the manufacturing industry and comprises a
robot mounting plate, pneumatic three-jaw chucks are embedded in the left side and the right side of the surface of the bottom of the
robot mounting plate, and sensor mounting plates are fixedly arranged on the surfaces of the left side and the right side of the
robot mounting plate. A
laser displacement distance measuring sensor is fixedly arranged below the outer side surface of the sensor mounting plate; when the device works, the robot drives the
brake drum gripper to move to the position above a workpiece, the lower portion of the pneumatic three-jaw chuck is right opposite to the position of a middle hole of the
brake drum, the robot gripper slowly descends until the clamping jaws fall into the middle hole of the brake drum, and after the
laser displacement distance measuring sensor senses that the distance of a product is a
set distance, the gripper stops falling. The pneumatic three-jaw chuck opens the clamping jaws, the brake drum is supported by the
friction force between the clamping jaws and the center hole of the brake drum, the robot drives the gripper and the workpiece to move, the product gripping work of the gripper is completed, automatic carrying is achieved, and the working efficiency is improved.
