Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to an edge polishing and grinding device for sheet metal parts. Background Technology

[0002] Sheet metal parts are core components in machinery manufacturing, automotive, and electronics industries. Their edge precision and surface smoothness directly affect the assembly accuracy, safety, and appearance quality of products. During the production of rectangular sheet metal parts, due to the limitations of stamping and cutting processes, burrs, flash, and rough surfaces are easily generated at the edges. These defects need to be eliminated through polishing and grinding to ensure product performance. Currently, the polishing and grinding of sheet metal parts edges mainly employs two methods: manual grinding or traditional single-machine grinding. Manual grinding relies on operators using handheld belt sanders, angle grinders, and other tools to process the edges of sheet metal parts one by one. This method is not only labor-intensive and inefficient, but the grinding quality is also significantly affected by the operator's skill level and working condition. It is difficult to ensure the consistency of edge grinding for each sheet metal part in mass production, and problems such as over-grinding and missed grinding are prone to occur, resulting in a low product qualification rate. While traditional stand-alone grinding equipment has replaced manual operation to some extent, it generally suffers from insufficient automation. Most existing equipment is designed for a single workstation, and can only grind one edge of a single sheet metal part at a time. To complete the grinding of all four sides of a rectangular sheet metal part, the workpiece clamping position needs to be adjusted multiple times, which is cumbersome and time-consuming.
