我厂生产的492Q汽油发动机,从六○年至今产量逐年增多,工艺装备不断更新,从实践中体会到其夹具的设计和制造是保证产品质量、提高效率的重要环节。铣492Q汽油发动机连杆螺栓台夹具,曾几次更新,目前采用的摇摆式夹紧工件夹具,效果较好,精度稳定,加工效率高,夹具结构见附图。一、使用方法: 夹具体1以两定位键33为基准和主轴垂直安装在专用机床或X62W铣床工作台上均可(刀具如点画线所示),用百分表固定在两对刀表架柱4上,校正刀具所需加工合理位置(用特制对刀块对出标准读数),夹具夹紧缸22经
The 492Q gasoline engine produced by our plant has been increasing in output since 1960 and has been continuously updated. The design and manufacture of its fixtures is an important part of ensuring product quality and efficiency. Milling 492Q petrol engine connecting rod bolt fixture, has been updated several times, the current use of the swing clamping workpiece fixture, the effect is better, accuracy and stability, high processing efficiency, fixture structure see the attached map. First, the use of methods: Clamp body 1 with two positioning keys 33 as the base and the spindle mounted perpendicular to the machine or X62W milling machine table can be (tool as shown by the dotted line), with a dial indicator fixed on the two pairs of tables Column 4, the calibration tool required for processing a reasonable position (with a special pair of knife out of the standard readings), clamp clamping cylinder 22 by
