本心轴由基体1、组合螺母2、定位销4及可换弹性涨套3组成。使用时,先根据被加工工件的要求,选配可换弹性涨套3,依靠基体1前端的锥体,将可换弹性涨套均匀缩开,夹紧工件即可进行车削加工。工件加工完毕,只要松劲组合螺母2,可换弹性涨套3则自动收缩即可快速卸工件。 该心轴结构简单,使用方便,实现了快速装卸工件,长期推广应用证明提高工效2～3倍。可换弹性涨套已经系列化(见表2)
The mandrel consists of a base 1, a combination of nuts 2, the positioning pin 4 and changeable elastic sleeve 3 composition. When used, according to the requirements of the workpiece to be machined, an optional elastic sleeve 3 can be selected. Depending on the cone at the front of the base body 1, the elastic sleeve can be retracted elastically and the workpiece can be clamped for turning. Workpiece processing is completed, as long as the combination of loose nut 2, changeable elastic sleeve 3 is automatically retracted to quickly unload parts. The mandrel structure is simple, easy to use, to achieve rapid loading and unloading of workpieces, long-term promotion of proven to improve ergonomics 2 to 3 times. Changeable elastic sleeve has been series (see Table 2)
