我厂曲轴生产线上,原采用C620车床车195柴油机曲轴墙板,存在着夹刀不紧、蹦刃、劳动强度大、工效低、质量差等问题。后将该机改造成半自动专机(图1),效果很好。当压力油进入夹紧油缸1的右腔时,活塞杆2带动滚子联轴器3,拉杆4,使带有四爪的弹簧夹头6在内锥体9内向左滑动,四爪夹紧工件。衬套7用以限制弹簧夹头转动,定位块8作工件轴向定位。当压力油进入夹紧油缸1左腔时,由活塞杆2、联轴器3、拉杆4使弹簧夹头向右滑动,四爪松开工件。夹紧油缸1紧固在床头箱上,夹具体5紧固在车
Crankshaft production line in our factory, the original use of C620 lathe 195 diesel engine crankshaft wall panels, there is clip tight, jump edge, labor-intensive, low efficiency, poor quality and other issues. After the transformation of the aircraft into a semi-automatic plane (Figure 1), the effect is very good. When the pressure oil enters the right cavity of the clamping cylinder 1, the piston rod 2 drives the roller coupling 3 and the pull rod 4 to slide the collet chuck 6 with four claws to the left in the inner cone 9 and clamp the four claws Workpiece. Bushing 7 is used to limit the collet rotation, positioning block 8 for the workpiece axial positioning. When the pressure oil enters the left chamber of the clamping cylinder 1, the collet is slid to the right by the piston rod 2, the coupling 3 and the rod 4, and the four claws release the workpiece. Clamping cylinder 1 fastened on the bedside box, clamp body 5 fastened in the car
