偏心套是圆锥破碎机的关键部件之一。国内已知的PY系列弹簧、西蒙斯、单缸、多缸以及HP(固定心轴)等圆锥破碎机,虽然其偏心套形状和尺寸各不相同,但基本部是外圆与内孔轴线倾斜,所以机械加工方法大体相同。根据丹东冶金机械厂多年加工此类工件的经验,对圆锥破碎机偏心套常用的几种加工方法作一对比。1 卧车简易胎具法见图1,用常规方法在卧车上加工好偏心套外圆,卧车卡—内孔轴线倾斜的圆柱孔胎,以内孔两端找零,装入偏心实,顶丝,将胎和偏心套固定成一体,用普通长刀杆镗车加工偏心套内偏心
Eccentric sleeve is one of the key components of cone crusher. Domestic known PY series springs, Simmons, single cylinder, multi-cylinder and HP (fixed mandrel) and other cone crusher, although the eccentric sleeve shape and size vary, but the basic part of the outer cylinder and bore axis tilt , So the machining method is roughly the same. According to Dandong Metallurgical Machinery Factory years of experience in the processing of such parts, cone crusher eccentric sets of several common processing methods for a comparison. 1 Sleeper simple tire method shown in Figure 1, using conventional methods in the sleeper processing eccentric sleeve, sleeper card - bore axis inclined cylindrical hole tire to the ends of the hole change, loading Eccentric solid, top wire, The tire and the eccentric sleeve fixed in one, with ordinary long bar cutter eccentric machining eccentric sleeve
