一种新型实用的牵引驱动增速刀柄

Develpment and Research of a New Practical Speed-raising Tool Holder

研制了一种由特制的牵引剂进行驱动、用于回转机床的增速刀柄,该刀柄能使刀具增速8倍而不改变原机床的任何结构和主轴转速。刀具增速后达到磨削速度,可实现模具型腔的复杂空间曲面的精加工,使普通NC铣床代替磨床,并解决了工件在一次装夹中实现从粗加工到精加工的全过程。该刀柄体积小、结构紧凑、传动平稳、无噪声。

A speed-raising tool holder which is drived by special traction agent is developed.Speed of tools can be raised8thimes without any change of the construction and spindle speed of machine.The high speed of tools meets need of the grinding,making it is possible for the high-precision of complicated surface of mould,thus NC milling machine may substitute sharpener,realizing the roughing,finishing if only the work piece is fixed on time.The tool holder is small,com pact,noiseless,expecially its transmission is sta ble.
