摘　　要：对开螺母主要应用于车床中,在车削螺纹时,对开螺母合上,丝杠转动,与其配合的对开螺母移动,从而带动溜板箱移动,并带动刀架作进给运动,加工螺纹。工作过程中,对开螺母抱合性能是否优良,操作是否方便,直接影响到被加工螺纹质量,影响到车床的工作效率。因此要对对开螺母进行合理的机械加工工艺分析,并设计合适的夹具进行机械加工,装配后才能发挥更好的优良性能。The nut is mainly used in lathe. When thread is threaded, the nut can be closed and the screw rod rotates, so that the nut can move with the matching nut, so as to drive the sliding box box to move, and drive the tool carrier to feed, and process the thread. In the process of working, whether the nut is good and the operation is convenient is directly related to the quality of the thread that is processed, and the efficiency of the lathe is affected.Therefore, to analyze the reasonable machining process on the nut, and suitable for machining fixture design, excellent performance can play a better after assembly.
