在机械加工中,经常遇到在同一个零件上需加工一些不同孔径的孔,需钻削、铰削、鍯孔、倒角等。由于单轴钻床只有一根主轴,就需频繁地更换刀具,这样,影响加工效率和产品质量的稳定,劳动强度也大。经使用快换多工位钻后,基本解决了上述问题。基本原理:快换多工位钻(如图),是根据结合面产生的摩擦力来传递扭矩的。主运动是由装有外锥摩擦头12的钻床主轴,通过装有内锥摩擦头13的从动轴来实现的。从动轴可以根据需要设计成六根或八根工作轴。锥体摩擦副接触压
In machining, often encountered in the same parts need to be processed some holes of different pore sizes, drilling, reaming, countersinking, chamfering and so on. As a single-axis drilling machine has only one spindle, you need to frequently change the tool, so that affect the processing efficiency and product quality and stability, labor-intensive. After using the quick change multi-station drilling, the basic solution to the above problems. Fundamentals: Quick change multi-station drill (pictured), is based on the friction generated by the interface to transmit torque. The main movement is carried out by a drilling spindle equipped with an outer-cone friction head 12, via a driven shaft equipped with an inner cone friction head 13. Driven axis can be designed according to the needs of six or eight work axis. Cone friction pair contact pressure
