PK型保持架兜孔拉削装置的设计

Design of Broaching Device for PK Type Cage Pockets

针对PK型保持架兜孔结构,设计专用拉削兜孔装置。该装置主要由传动系统、工件支承机构、工件夹紧机构以及工件上下料机构组成。通过伺服电动机驱动传动系统,借助蜗轮蜗杆实现摆动分度运动,由电气控制工件的支承与夹紧,从而实现兜孔拉削装置的全自动工作循环。新装置改善了PK型保持架兜孔的表面精度,提高了加工效率。

According to structure of PK type cage pockets, the special broaching device is designed. The device is mainly composed of transmission system, workpiece support mechanism, workpiece clamping mechanism and workpiece loading- unloading mechanism. The transmission system is driven by servo motor to realize swing and indexing move- ment by means of a worm gear. The support and clamp of workpiece are controlled by electric, and the automatic work- ing cycle of broaching device for pockets is realized. The surface accuracy of PK type cage pockets is improved, and the work efficiency is improved.
