电机转子激光焊接系统设计

Design of laser welding system for motor rotor

针对电机转子中套筒、护盖的焊接,设计了激光焊接系统。由于整个工件组合后长度和位置的尺寸存在一定的尺寸公差,需设计特殊夹具吸收其公差。激光焊接夹具包括随行夹具、顶升组件、上止档组件及转盘夹具,将工件置于随行夹具内,顶升旋转组件将工件顶入上止挡组件,以转子的上端面作为定位基准面,实现对工件的精确定位焊接。

The laser welding system was designed for the sockets and cover of motorrotor. Because of the tolerance of the length and the installing dimensions after the ork-pieces being assembled,the special fixture was designed to absorb the tolerance which consists of the swiched fixture,jacking component,up-stop component and rotary fixture. The work-pieces were fixed in the swiched fixture and jacked upwards the upstop component,which used the upper surface as the position datum,realized the positioning for the work-piece precisely.
