蜗轮蜗杆减速器壳体工艺及夹具设计
摘 要
本设计专用夹具的设计蜗轮蜗杆减速器壳体零件加工过程的基础上。主要加工部位是平面和孔加工。在一般情况下，确保比保证精密加工孔很容易。因此，设计遵循的原则是先加工面后加工孔表面。孔加工平面分明显的阶段性保证粗加工和加工精度加工孔。通过底面作一个良好的基础过程的基础。主要的流程安排是支持在定位孔过程第一个，然后进行平面和孔定位技术支持上加工孔。在随后的步骤中，除了被定位在平面和孔的加工工艺及其他孔单独过程。整个过程是一个组合的选择工具。专用夹具夹具的选择，有自锁机构，因此，对于大批量，更高的生产力，满足设计要求。 关键词：蜗轮蜗杆减速器壳体类零件；工艺；夹具；

ABSTRACT
Foundation design of body parts processing process the design of special fixture. The main processing parts processing plane and holes. In general, ensure easy to guarantee precision machining holes than. Therefore, the design principle is first machined surface after machining hole surface. Periodic hole machining plane is obvious that rough machining and machining precision machining hole. A good foundation on the bottom surface of the process. The main process is supported in the positioning hole process first, and then the processing hole plane and the hole positioning technology support. In a subsequent step, in addition to processing technology are positioned in the plane and the other hole hole and separate process. The whole process is a combination of the selection tool. Special fixture fixture selection, a self-locking mechanism, therefore, for large quantities, higher productivity, meet the design requirements.
