Description

Technical Field

[0001] The invention belongs to the technical field of polishing, and in particular relates to a polishing device for manufacturing automobile sheet metal parts. 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 flat surface. Polishing is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media. The polishing process of automobile parts requires a polishing machine. The working principle of the polishing machine is to drive the polishing disc installed on the polishing machine to rotate at high speed through a motor. The polishing disc and the polishing agent work together and rub against the surface to be polished, thereby achieving the purpose of removing paint pollution, oxide layer, shallow marks, etc. From the existing technology, common automobile parts are polished and polished manually, which is time-consuming and laborious. The few polishing devices use a clamping mechanism to clamp the polishing object, and then use sandpaper and grinding tools for polishing and grinding. However, during the polishing process, the temperature of the polishing object often rises with the increase of friction and time, and it is easy to deform. In addition, debris is easy to generate during the polishing process. The debris is easy to cause pollution of the polishing object, affecting the polishing efficiency, and the debris of the existing polishing device cannot be collected.

Since the base is threadedly connected to the threaded rod through a threaded hole, the rotating motor drives the base to slide on the guide rail. Since an auxiliary rail is installed on one side of the guide rail, a sliding table is slidably connected to the auxiliary rail. The sliding table and the base are connected by a cross bar, which makes the sliding more stable.

[0017] 4. The present invention utilizes a polishing motor to drive the driving wheel to rotate. Since the driving wheel is meshed with the driven wheel, and the driven wheel is fixedly connected to the rotating wheel, the polishing motor drives the rotating wheel to rotate. Sandpaper is sleeved on the outer side of the rotating wheel. The reverse low-speed rotation of the sandpaper is utilized to polish and grind the polishing object.
