齿轮箱加工工艺设计

齿轮箱零件小且形面复杂，空间尺寸不便于测量．加工部位多。要求有几何公差的部位多且要求几何公差值严格．以致于在加工中难以控制。本文针对零件结构特点及其精度要求．阐述了该零件的工艺设计思想及具体内容，详细介绍了加工设备HPM1150U机床的特性以及专用组合夹具的结构特点。为小零件、多形面、多部位的零件加工问题提供了较好的解决办法。

Design of Machining Process of Gear Boxes

Gear box parts are small and complicated, it is not easy to be measured in its special dimensions, its many po- sitions with more shape and position tolerances and the strict requirements to be machined make it difficult to be held during machining as well. The paper presented the process design idea and the concrete contents of this part aiming at the structural characteristics and the precision requirements. It introduced the performance of the machining equipment HPMll50u ma chine Iooland the structural characteristics of the special fixture in details. The paper provided a good solution for machining the small paris with more faces,more positions.
