1.动臂校正原因装载机动臂主要由左臂板、右臂板、箱形横梁等部件焊接而成,结构如图1所示。焊接装载机动臂过程中,容易出现2个问题,一是由于左、右臂板与箱形横梁组焊的焊角较高(高度为30mm),使左、右臂板极易产生收缩变形;二是由于左、右臂板端部延伸较长,且无刚性约束,易于造成
1. Boom calibration reasons Loader boom mainly by the left arm plate, right arm plate, box beams and other components welded together, the structure shown in Figure 1. There are two problems in the process of welding the loader boom. One is that the welding angle between the left and right arm plates and the box beam is relatively high (the height is 30mm) so that the left and right arm plates can easily shrink and deform. Second, due to the left and right arm plate extension of the longer, and no rigid constraints, easy to cause
