可调节锥面键槽铣削夹具的设计

Design of Adjustable Milling Fixture for Taper Keyway

传统锥面键槽铣削夹具存在两方面问题。当工件上锥面锥角发生变化时,夹具不能适应,需要进行改进。当工件锥面有对称的两个键槽时,需要两次定位。对此,设计了可调节锥面键槽铣削夹具。介绍了可调节锥面键槽铣削夹具的结构和原理,采用一套夹具可以加工不同上锥面锥角的工件,当工件锥面有对称的两个键槽时,只需要一次定位。可调节锥面键槽铣削夹具能够提高生产效率,节省制造成本,应用效果良好。

There are two problems in the traditional milling fixture for taper keyway.When the taper angle of the tapered face on the workpiece changes,the fixture is inadaptable and needs to be improved.When the tapered face of the workpiece has two symmetrical keyways,it is required to be positioned twice.In this regard,an adjustable milling fixture for taper keyway was designed.The structure and principle of the adjustable milling fixture for taper keyway were introduced.Only one fixture can be used to process workpiece with different taper angle at supper tapered face.When the workpiece tapered face has two symmetrical keyways,only one positioning is required.The adjustable milling fixture for taper keyway can improve production efficiency,save manufacturing costs,and have good application effects.
