真空泵滑阀加工专用刨床设计

Design of Special Planer for Machining Vacuum Pump Slide Valve

针对真空泵滑阀现有加工技术存在的插床加工效率低、质量稳定性差,多轴数控龙门刨床加工设备投入大等问题,设计了一种滑阀加工专用刨床。基于普通牛头刨床进行胀紧定位、滑阀旋转、刨刀进给等机械结构设计和控制系统智能化改造,采用PLC控制,以触摸屏作为人机交互界面,实现滑阀全自动加工。通过生产验证,专用刨床能达到多轴数控龙门刨床的加工效能,相对于传统插床加工,生产效率和产品合格率都得到大幅提升。

Aiming at the problems that low machining efficiency and poor quality stability of the slotting machine,and high investment of the multi-axis CNC gantry planer in the existing machining technology of the slide valve of the vacuum pump,a special planer for machining slide valve is developed.The mechanical structure design,such as expansion and positioning,the rotation of the slide valve,the movement of the planer,and intelligent reform of the control system are carried out based on the common shaper.Using PLC control and touch screen as a human-computer interface to achieve automatic machining of the slide valve.The production verification shows that the special planer can achieve multi-axis CNC gantry planer machining efficiency,and the production efficiency and product qualification are greatly improved compared with traditional slotting machine machining.
