本文介绍一种加工范围为φ40～72毫米的中小型轴承套圈锻件自动车床。这种机床以单刀架进行多刀加工,按固定程序动作,先加工端面,后加工内径(外径)和倒角。纵横刀架为双层矩形导轨,强力润滑,用径向复合油缸驱动——大缸工作进给,小缸快进或让刀。夹紧油缸采用固定式。自动上下料装置设计有摇摆式机械手和落料槽。本机单件时间为16秒,平均班产量为(305/01)1100～1300件。车削质量完全能满足工艺技术条件的要求。本机采用30°弯头断屑刀断屑,以夹具中的70°锥孔定位套排屑。附图6幅,表2个。
This article describes a processing range of φ 40 ~ 72 mm for small and medium sized bearing rings forging automatic lathe. This machine tool to multi-tool single-pole processing, according to a fixed procedure, the first processing of the end surface, after the processing of diameter (diameter) and chamfer. Vertical and horizontal turret for double rectangular rail, strong lubrication, with radial composite cylinder drive - cylinder feed, small cylinder fast forward or let the knife. Clamping cylinder with a fixed. Automatic loading and unloading device designed with swing robot and blanking tank. The unit time is 16 seconds, the average class production (305/01) 1100 ~ 1300 pieces. Turning quality can fully meet the technical requirements of the conditions. The machine adopts 30 ° elbow chip breaking knife chip breaking, 70 ° taper hole positioning sleeve chip sets in the fixture. Figure 6, Table 2.
