汽车后钢板弹簧吊耳零件专用夹具设计

Special Fixture Design for Rear Leaf Spring Lifting Lug Parts

为实现对汽车后钢板弹簧吊耳零件钻孔工艺加工,设计了一套液压专用自动夹具。针对工件特点,采用完全定位方案,设计了液压夹紧机构,计算了切削力和夹紧力,根据夹紧力的大小选用了液压油缸。选用了相应的钻套、钻模板,设计了夹具体。实践证明,该套夹具结构简单,能够保证加工精度,提高了加工效率。

A set of hydraulic special automatic clamp is designed to realize drilling process of the rear leaf spring lifting lug parts. According to the characteristics of workpiece, the hydraulic clamping mechanism is designed, the cutting force and clamping force are calculated, and the hydraulic cylinder is selected according to the clamping force. The corresponding drill sleeve and drill template are selected to design the clamping fixture. It is proved that this fixture with simple structure can be used to ensure the machining accuracy and improve the machining efficiency.
