我厂生产的剪板机上有一种为调整刀片间隙用的偏心轴,偏心距e=1.4mm。为确实保证其偏心距要求,设计了一种夹头,使用状况见附图。首先按一般加工轴类的方法,车好无偏心的轴,如轴上有键槽,要先加工好键槽。然后装入该夹头孔内,在车床上找正位置,此时工件的上母线和侧母线应和床鞍移动方向平行,将夹头的夹紧螺钉拧紧,就可以车制轴的偏心段了。
I have a factory for cutting plate machine for adjusting the gap with the eccentric shaft, eccentricity e = 1.4mm. To ensure its eccentricity requirements, designed a chuck, the use of the conditions shown in the drawings. First of all, according to the general method of processing shaft type, the car is good non-eccentric shaft, such as the shaft keyway, the first key groove processing. And then loaded into the chuck hole in the lathe to find a positive position, then the workpiece on the bus and the side bus bar should be parallel to the direction of movement of the saddle, the chuck clamping screw tighten, you can car axis eccentric section It’s
