Description

Technical Field

[0001] The utility model belongs to the technical field of pipe processing equipment, in particular to a pipe polishing device. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process on the workpiece surface using polishing tools and abrasive particles or other polishing media. A polishing machine is also called a grinder, which is often used for mechanical grinding, polishing and waxing. Polishing is mostly to reduce rust marks on the surface of the pipe, reduce the erosion of rust on the surface of the pipe, and facilitate painting.

[0003] In order to improve the polishing effect and effect on the inner and outer walls of the pipe, the existing polishing equipment for pipe processing often adopts a combination of an inner grinding rod and an outer grinding wheel to improve the polishing effect of the device on the pipe, facilitate subsequent painting, and increase the service life of the pipe. However, during the polishing process, the existing device cannot process and collect the debris generated by the polishing of the pipe surface, which splashes everywhere and causes harm to the surrounding operators, reducing the practical safety of the device.

[0004] For example (authorization announcement number CN214817660U) a pipe polishing includes a polishing mechanism and a positioning mechanism; the polishing mechanism includes a motor installed on a polishing base, and the output end of the motor is connected to a polishing roller for polishing the inner wall of the pipe through a coupling structure; the positioning mechanism includes a positioning fixture arranged on the outside of the polishing roller, the positioning fixture includes a fixed clamp block and two movable clamp blocks, and the fixed clamp block and the two movable clamp blocks are arranged in a circular array on the outside of the polishing roller; the fixed clamp block is arranged directly below the polishing roller, and the two movable clamp blocks are symmetrically arranged on the left and right sides of the polishing roller; the bottom of the fixed clamp block is fixedly connected to the positioning base, and the top ends of the two movable clamp blocks are connected to inclined driving cylinders. The device solves the problem that the existing equipment cannot be adjusted according to the aperture size. However, when processing the bright surface, the device cannot handle the debris generated by polishing, which splashes everywhere and causes harm to the operator, reducing the safety of the device.
