题目：溜板箱机械加工工艺规程及镗孔夹具
摘要：溜板箱是将丝杠和光杠传来的旋转运动转变为溜板箱的直线运动并带动刀架进给，控制刀架运动的接通、断开和换向。当机床过载时，能使刀架自动停止；还可以手动操纵刀架移动或实现快速运动等。固定在鞍座上，并悬挂在床身的前面。它包括齿轮、离合器及手动和自动进给床鞍用的手柄。溜板箱上有一个小齿轮。而小齿轮又与床身前下面的齿条相啮合，可用手转动溜扳箱手轮，可使床鞍纵向移动。溜板箱包括自动进给用的摩擦离合器和开合螺母,开合螺母停靠在丝杠螺纹的上方，仅在车螺纹时使用。
 

Abstract：The apron is transmits the guide screw and the feed rod turns on lathe the transportation to turn becomes the apron the translation and the impetus tool rest enters gives, controls the tool rest movement to put through, the separation and the commutation. When the engine bed overloads, can cause the tool rest automatically to stop; Also may the hand operated tool rest move or the realization quick movement and so on. Fixes in the saddle place, and is hanging in lathe bed front. It including the gear, the coupling and manual and automatically enters the handle which uses for the bed saddle. Slides pulls in the box to have a pinion. But the pinion the under rack meshes with the lathe bed in front of, may use the hand starting or cranking to slide pulls the box handwheel, may cause the bed saddle longitudinal shift. The apron including automatically enters for the friction clutch and opens and closes the nut with,Opens and closes the nut to anchor in the guide screw thread place above, only when cutting thread uses.
