仪表小模数齿轮零件精细。因此,在加工过程中,采用合理的装夹方式、灵巧的夹具结构,对于提高加工精度和生产效率是很重要的。本文根据我厂的生产实践,着重介绍几种滚切小模数齿轮的夹具结构。这些夹具具有结构简单,制造工艺性好,装夹方便,使用可靠,性能稳定等优点。它的特点是使加工基推和工作基准、设计基准完全一致,提高了零件精度。我们在Y304、YG3603滚齿机上,采用A级滚刀,配上这些夹具,可以成批加工六级精度的小模数齿轮。 Instrument small modulus gear parts fine. Therefore, in the process of processing, using a reasonable way of clamping, smart fixture structure, to improve the machining accuracy and production efficiency is very important. Based on the production practice of our factory, this article focuses on the fixture structure of several hobbing gear. These fixtures have the advantages of simple structure, good manufacturability, convenient installation, reliable use and stable performance. Its characteristic is to make the base of processing and work base, the design basis is exactly the same, improve the accuracy of the parts. We Y304, YG3603 gear hobbing machine, with A-level hob, coupled with these fixtures, batch processing six small precision gear.
