摘要
液压钻机钢制油管用来连接固定油口,油管接头属于焊接式管接头,由接管和无缝钢管焊接而成,当无缝钢管长度较短时,不能弯曲变形,对焊接定位精度要求高。根据90°弯油管及接头的特点,设计气缸推动的活动定位销与固定定位销组成的焊接工装,配合使用环缝焊机实现批量化焊接。
The hydraulic drilling steel pipe is used to connect the fixed oil port ,the oil pipe joint belongs to the welded pipe joint, which is welded by the seamless steel tube. When the length of the seamless steel tube is small,it can not be bent and deformed. According to the characteristics of the 90°oil pipe and the joint, the welding fixture which is composed of a movable positioning pin and a fixed positioning pin which is driven by the cylinder is designed, and the utility model is used to realize the batch welding with the girth welding machine.
