Polishing device for pipe orifice of heat exchange pipe

Abstract

The utility model discloses a heat exchange pipe orifice polishing device which comprises a workbench, the top of the workbench is fixedly connected with a supporting plate through bolts, one side of the supporting plate is provided with a polishing wheel, the outer wall of the polishing wheel is rotationally connected with a fixing frame through a bearing, and the end, extending out of the fixing frame, of the polishing wheel is fixedly connected with a servo motor. The outer wall of the servo motor is fixedly connected to the outer wall of the fixing frame, and the fixing device is arranged above the supporting plate. The utility model relates to the technical field of heat exchange tube polishing, through the cooperation of a pressing plate, a connecting plate and a threaded rod, a heat exchange tube is placed on a supporting plate, a rotating handle is rotated, and through the threaded connection of the rotating handle and the outer wall of the threaded rod, the threaded rod drives the connecting plate to ascend and descend, the pressing plate is pressed on the top of the heat exchange tube, and the supporting plate and the pressing plate clamp the heat exchange tube together. In this way, the problem that the clamping plates are unstable under the action of gravity of the heat exchange tubes is solved.
