在焊接现场,零构件之间一般都要用胎夹具来夹紧定位,但有些夹具在生产中使用起来并不理想,需要不断地进行改进。例如;我车间在立管臂与两端法兰盘焊接时,最初是使用顶丝式夹具夹持,但由于装卸不方便,后来干脆改用手持别棍来夹紧。这样在每个操作人员身边都增加了一个人来扳别棍,尽管这样暂时装卸方便了一点,但却浪费了人力,焊接质量也并不理想。为此,我们又重新设计了一种 In the welding site, the components are generally used between the clamps to locate the fixture, but some fixtures used in the production is not satisfactory, the need for continuous improvement. For example, in the workshop, when the stand pipe arm was welded with the flanges on both ends, the top wire clamp was used for the first time. However, due to the inconvenience of loading and unloading, the clamp was simply replaced by a handheld stick. This added an individual to each operator to pull the stick, although the temporary loading and unloading a little easier, but wasted manpower, welding quality is not satisfactory. To this end, we have redesigned one
