一种新颖的功能部件——机械蓄能式定位、换向机构(以下简称机构,见附图1),已经成功地应用在我厂主要产品X6325型万能摇臂铣床上,使机床工作台的移动具备下列功能:(1)纵向机动进给并可在其行程范围内的任一位置自动定位;(2)纵向自动往复进给;(3)在纵向往复进给换向的瞬间,横向自动进给一段所需要的距离;(4)纵横向均可手摇进给且很轻巧。这些功能的实现都无须改变进给电机的正向旋转状态,这对节约能耗,延长电机使用寿命,简化机床结构和电气控制系统都有利。该机构稳定可靠,操作轻便。一、传动简介如图1所示,进给电机的动力经变速箱从锥齿轮20单转向输入,由丝杠19输出。双向离合器21的作用
A new feature - mechanical accumulator positioning, reversing mechanism (hereinafter referred to as the mechanism, see Figure 1), has been successfully used in our main products X6325 universal rocker milling machine, the machine table Mobile has the following functions: (1) Longitudinal motor feed and can be automatically positioned in any position within its travel range; (2) Vertical reciprocating feed; (3) In the longitudinal reciprocating feed commutation moment, Feed a section of the required distance; (4) Both horizontal and vertical can be fed by hand and very lightweight. The realization of these functions without changing the forward rotation of the feed motor, which is saving energy, extending motor life, simplify the machine structure and electrical control systems are beneficial. The agency is stable and reliable, easy to operate. First, the transmission profile As shown in Figure 1, the feed motor power from the bevel gear 20 single steering input, output by the screw 19. The role of the two-way clutch 21
