Description

钣金焊接夹具Sheet Metal Welding Fixtures

技术领域technical field

本发明涉及一种工装，具体涉及到焊接夹具。The invention relates to a tool, in particular to a welding fixture.

背景技术Background technique

在钣金行业中，为了节约电力成本，对于尺寸较小的钣金件的焊接一般不会采用冲压机，而是设计对应的钣金焊接夹具进行钣金焊接。例如焊接面为侧面，且无法夹紧顶面时，通常选择抵顶工具压紧端面，从而对焊接面进行焊接处理。然而在焊接时，由于焊接部位(位于焊接面上)以外的位置因无遮盖，从而在焊接部位周边的位置会产生焊渣，故而会影响钣金件的外观质量以及使用等等，使得焊接件报废。In the sheet metal industry, in order to save electricity costs, a stamping machine is generally not used for welding small-sized sheet metal parts, but a corresponding sheet metal welding fixture is designed for sheet metal welding. For example, when the welding surface is a side surface and the top surface cannot be clamped, an abutment tool is usually selected to press the end surface, so as to weld the welding surface. However, during welding, since the position other than the welding part (located on the welding surface) is not covered, welding slag will be generated around the welding part, which will affect the appearance quality and use of the sheet metal parts, etc., making the welded parts scrapped.
