罩类零件数控车削外形夹具的机构设计及方法探讨

Mechanism Design and Method of Fixture for NC Turning of Cover Parts

介绍一种罩类零件数控车削外形夹具,包括外锥度螺纹夹具体、内锥度螺纹夹具体和罩类零件。夹具的锥面与零件的内外锥面分别定位,通过螺纹旋合压紧来达到车削罩类零件外形的目的,解决了薄壁锥形罩类回转零件无法装夹、刚性不足易振动的难题。

This paper introduces a CNC turning profilefixture for hood parts, including the outer taper thread clamp, theinner taper thread clamp and the cover parts. The tapered surfaceof the clamp is positioned separately from the inner and outertapered surfaces of the part, and the shape of the turning cover typeis achieved by screwing and pressing. The invention solves theproblem that the thin-walled cone-type rotating parts can not beclamped, and the rigidity is insufficient to vibrate.
