高压齿轮油泵泵体平面上的曲线槽(装O型密封圈用),通常是用仿形铣床加工。我厂试制车间克服没有仿形铣床的困难,因陋就简,革新改制成一台铣曲线槽夹具(见附图),仅用通用铣床(主、卧式均可),以中心孔钻作铣刀,便可加工出合格零件。该夹具利用凸轮靠模原理,结构比较简 High-pressure gear pump pump curve plane groove (O-ring installed), is usually processed by copying milling. I workshop trial workshop to overcome the difficulty of not copying the milling machine, due to the simple, innovative conversion into a curved groove clamp fixture (see photo), only with universal milling machine (main, horizontal can be) to drill the center hole milling cutter, then Machinable qualified parts. The use of the principle of cam by the fixture, the structure is relatively simple
