大多深孔类工件,如气缸孔、油缸孔、塑料挤出机.注塑机机筒等,不仅内孔长,硬度要求高,而且还需很高的表面光洁度.要保证如此的精度,深孔加工最后一道工序必定是内孔珩磨.过去所采用的都是弹簧式珩磨头,是靠弹簧支撑砂条进行珩磨,这种珩磨方式不仅珩磨量小,珩磨所需时间长,而且不能调节珩磨量.对于表面硬化处理过的,以及由于上道扩孔工序中造成内孔表面有划伤痕迹而需进行大切屑量珩磨以此补救的孔,珩磨更是困难.针对这些问题,我设计了一种可调式强力珩磨装置,如图示:它是由珩磨头、砂条座、砂条,调节杆、珩磨杆、密封圈、调节座以及锁紧螺母和调节手柄组成.
Most of the deep-hole workpieces, such as cylinder bore, cylinder bore, plastic extruder, injection molding machine barrel, etc., not only long bore, high hardness requirements, but also high surface finish.To ensure such precision, deep hole The last process must be processed within the hole honing in the past are used spring honing head, is supported by the spring sand honing, this honing not only honing a small amount of honing time required, and can not adjust the amount of honing Honing is even more difficult for hardfaced holes that need to be honed by large chip honing due to scratches on the inner hole surface during the reaming process. Adjustable power honing device, as shown: It is composed of honing head, sand seat, sand, adjusting rod, honing rod, sealing ring, adjusting seat and lock nut and adjusting handle.
