【摘要】 在卧式加工中心上配置回转夹具是国内外机床制造技术的发展方向。卧式加工中心配置回转夹具主要是由夹具体、伺服电机、转台和液压系统等装置组成的一种复杂的夹紧结构,适用于汽车行业缸体、缸盖等零件的加工,在卧式加工中心装配调试工作中,经常遇到卧式加工中心配置回转夹具(转台+夹具)专机,而确定回转夹具回转中心位置成为该专机调试工作的技术关键,该文主要研究回转夹具回转中心的确定,夹具主定位面(含定位销)误差的判断、调整及其机床三个坐标轴运动之间的关系。更多还原

【Abstract】 Dispose the swing fixture on horizontal machining center is the developing direction of both here and abroad manufacturing technology.The horizontal machining center disposes swing fixture is a complex clamping structure,which is mainly composed by fixture,servo motor,revolving table and hydraulic system etc.It is used for machining the cylinder of automotive and cylinder cap etc.In horizontal machining center assembling and debugging work,often meets the special plane,which is horizontal machining center disposes swing fixture(revolving table+fixture),and to make sure the position of swing fixture and gyration center become the technique key in this debugging work.This article is mainly study the definition of swing fixture and gyration center,the error judgment and adjustment of fixture main locating surface(include locating pin),and the relation of 3 coordinate axis motion.更多还原
