齿圈类零件加工工艺创新性研究

Innovative Research of Processing Technic for Gear Ring Parts

由于齿圈类零件的壁较薄,在加工过程中装夹难度大,导致加工的产品精度总是无法达到设计要求。分析得出产生问题的主要原因,通过对工艺规程进行创新性设计解决这一问题,通过加工实验,工艺中采用线切割机慢走丝机床对零件进行加工,不但可以保证零件的设计要求,还使得产品合格率提高到98%、加工成本降低30%、加工周期缩短40%,在同类零件加工中具有一定的市场推广价值。

Due to the thinner wall of the gear ring parts, it is difficult to clamp in the machining process, and the precision ofthe processed products cannot always meet the design requirements. The main reason is analyzed in this paper, and this prob-lem is solved through the innovative design of the processing technic. Through the machining experiments, using WEDM-LSas the cutting machine in the processing technic could not only ensure the design requirements of parts, but also raise the prod-uct qualification ratio to 98%, lower the processing costs by 30%, and shorten the processing cycle by 40%. Thus it has acertain marketing value in the similar parts processing.
