Description
技术领域 technical field
本实用新型涉及一种夹具，特别涉及一种激光焊接夹具。 The utility model relates to a fixture, in particular to a laser welding fixture.
背景技术 Background technique
激光焊接技术是在材料加工方面应用最广泛的一种，运用在很多行业，包括轮船制造业、汽车制造业、建筑业及航天制造业等。在激光焊接过程中通常用夹具将待焊接件固定而后进行焊接。但由于热应力的存在，常常要求在焊接过程中拼焊间隙不发生变化或者间隙越小越好，这就对焊接夹具夹紧力的要求较高。但是在焊接过程中待焊接件常常会发生热变形从而导致焊接间隙发生变化，极大的降低了焊接的质量。 Laser welding technology is the most widely used in material processing, used in many industries, including ship manufacturing, automobile manufacturing, construction and aerospace manufacturing. During the laser welding process, fixtures are usually used to fix the parts to be welded and then welded. However, due to the existence of thermal stress, it is often required that the tailor welding gap does not change during the welding process or that the smaller the gap, the better, which requires higher clamping force of the welding fixture. However, during the welding process, the parts to be welded often undergo thermal deformation, which leads to changes in the welding gap, which greatly reduces the quality of welding.
