牛头刨床只有横向进给机构,垂直进给靠手动,既费力又不方便,加工光洁度也差,为了解决这个问题,我厂在刨床上增加了垂直进给机构(见图)。滑枕往返一次,顶杆2碰到床身上的盾铁3,带动摆杆10做定轴摆动,摆杆上端拨动拨叉9带动拨盘8转动,拨盘的另一端装棘爪6带动棘轮7,棘轮与丝杠用销钉5固死,则完成一次进刀。顶杆靠拉簧4复
Shaper only transverse feed mechanism, vertical feed manually, both laborious and inconvenient, poor machining finish, in order to solve this problem, I plant in the planing machine increased vertical feed institutions (see photo). The ram 2 reciprocates once, the ram 2 touches the shield iron 3 on the bed body, drives the swing rod 10 to make the fixed axis swing, the upper end of the swinging rod pushes the fork 9 and drives the dial 8 to rotate, the other end of the dial is loaded with the pawl 6 Ratchet 7, ratchet and lead screw 5 with the death, then completed a feed. Ram by the spring 4 complex
