我厂在加工车床主轴孔(内锥孔)的过程中,所使用的量具、检具等工装工艺要求锥度一致。以前在加工各种量、检具工装时,采用制造二次套规与各种量检具工装相互配研的工艺方法。采用这种方法,存在相互配研表面容易划伤、锥度一致性差、生产周期性长等缺点,影响了产品质量。经过探索,我们研制出一种简便、 I plant processing lathe spindle hole (taper hole) in the process, the use of measuring tools, gages and other tooling process requirements taper. In the past when processing a variety of quantities, check tooling, the use of manufacturing secondary sets of rules and a variety of fixture with the mutual research process. Using this method, there is mutual research surface scratches easily, conicity is poor, the long cycle of production and other shortcomings, affecting product quality. After exploration, we have developed a simple,
