为防止挖掘机动臂支座焊接时产生较大的焊接变形,需要在动臂及动臂缸安装部位预留适当的加工余量。为了控制动臂支座焊接变形量并达到取消加工余量的目的,经研究,我们决定对动臂支座结构和焊接工艺进行改进。1.改进结构(1)改进前的结构动臂支座改进前的结构如图1所示。其立板先与筋板1焊接后,再与加强板1焊接,采用这种结构
In order to prevent the excavator boom support welding large welding deformation, the boom and boom cylinder mounting parts need to set aside the appropriate allowance. In order to control the amount of welding deformation of the boom support and to eliminate the machining allowance, we decided to improve the boom support structure and welding process after research. 1. Improve the structure (1) to improve the structure before the boom support to improve the structure shown in Figure 1. The vertical plate first welded with ribs 1, and then welded with the strengthening plate 1, using this structure
