不论是传统制造系统,还是现代制造系统,夹具都是机械制造系统的重要组成部分,而机床夹具技术正朝着高精、高效、模块、组合、通用和经济方向发展。指出了M250A普通内圆磨床在利用节圆定位夹具磨削ZL50装载机驱动桥主减速器齿轮副中从动锥齿轮内孔时,手动机械夹紧的缺陷,阐明了液压夹紧在M250A机床改造中特征及其在ZL50装载机驱动桥从动锥齿轮内孔磨削中的优点及应用结果。
Whether it is a traditional manufacturing system or a modern manufacturing system, jigs are an important part of a mechanical manufacturing system, and machine tool technology is moving toward high precision, high efficiency, modularity, assembly, versatility and economy. The paper points out the defects of manual mechanical clamping when the M250A ordinary internal grinder grinds the bore of driven bevel gear in the gear pair of the main reducer gearbox of ZL50 loader drive axle by using the pitch positioning fixture, In the ZL50 loader drive axle driven bevel gear inner hole grinding advantages and application results.
