Technical Field

[0001] This utility model relates to the field of irregular sheet metal processing technology, and in particular to a laser cutting fixture suitable for irregular sheet metal parts. Background Technology

[0002] In laser cutting, workpiece positioning and clamping are key factors affecting processing quality. Existing laser cutting fixtures are mainly suitable for fixing regularly shaped sheet metal, such as rectangular and circular plates. These traditional fixtures typically employ clamping, pneumatic adsorption, or magnetic fixing structures. When dealing with irregularly shaped sheet metal parts, these fixtures often fail to provide stable and reliable support and clamping force, exhibiting the following main problems: few fixing points, failing to provide all-around support for irregularly shaped workpieces, leading to vibration or displacement during cutting; small contact area between the fixture and the workpiece, resulting in insufficient clamping force and affecting cutting accuracy; poor adaptability, as the same fixture cannot adapt to irregularly shaped workpieces of different sizes; and complex adjustment processes, requiring fixture resetting when changing different workpieces, reducing production efficiency. Therefore, a laser cutting device suitable for irregularly shaped sheet metal parts is needed. Utility Model Content
