Description

Technical Field

[0001] This utility model relates to the field of automotive polishing technology, specifically a polishing device for processing automotive door frames. Background Technology

[0002] The door frame is the core support structure inside the car door, which directly affects the door's strength, safety, and functionality. During the automobile manufacturing process, the processing precision and surface quality of the door frame directly affect the door's assembly effect and service life.

[0003] Traditional car door frame grinding mainly relies on manual operation or semi-automatic equipment. Manual operation is easily affected by fatigue and skill level, resulting in uneven grinding and affecting the quality of the workpiece. In addition, a large amount of metal dust is generated during the grinding process. Traditional equipment has poor dust removal effect, which harms the health of workers and pollutes the environment. Furthermore, it is inconvenient to adjust and fix it according to the specifications of the car door frame, which affects the practicality of the grinding device. Therefore, we propose a grinding device for processing car door frames. Utility Model Content
