工件回转式小直径内排屑数控深孔钻床的设计 摘 要：制造业是一个国家或地区经济发展的重要支柱，其发展水平标志着该国家或地区的经济实力、科技水平、生活水准和国防实力。而制造业的生产能力主要取决于制造装备——机床的先进程度。 本设计所研究的深孔钻床用于加工孔径比（D/L）为1：10以上的深孔，如钻杆，枪管、炮筒和机床主轴等部件中的深孔。它的工作原理是变频电机驱动的主轴带动工件旋转实现主运动，伺服电机带动丝杠旋转，使置于溜板箱上的主轴系统做横向进给运动。在进给切削工件的同时供油系统向授油器提供高压切削液，切削液流向钻头冷却工件，并携带切屑从钻杆芯部流向钻杆箱排出，由回油路流回油箱。油箱的箱体中装有隔板和滤油装置，保证脏物能够沉淀，使切削液能够更好的重复循环使用。 首先从切削力入手确定主轴电机，机床的控制整个机床的结构Design For Small Diameter rotary workpiece of BTA CNC Deep Hole Drilling Machine Abstract：The Manufacture is an important support of economic development in a country or area. Its level of development stands for the economic power, technical and scientific level, living standard and national defensive power of the country or area. While the capability of production in trade of manufacture mostly depends on the advanced producing equipment－machine tool. The design of the deep hole drilling machine for processing aperture ratio (D / L) of 1: or more deep,Such as the barrel, barrel and spindle and other parts of the deep hole. It works by variable frequency motor drive the main spindle drive rotation of workpiece movement, servo motor driven lead screw rotation to be placed on the spindle box slide board lateral feed motion of the system to do. Cutting the workpiece in the feed oil supply system, while providing high-voltage device to grant oil cutting fluid, cutting fluid flow cooling of the drill bit and carry drill cuttings from the drill core boxes the Department of flow discharge, flow back into the tank by the return oil line. The box is equipped with a diaphragm tank and Oil Filters, ensure that dirt can be precipitated, so that duplication of cutting fluid can be better recycled. Starting from the cutting force required to determine the spindle motor power and thus determine the type and model of the machine control system combining the structure and layout of contact tasks require the whole machine tool structure size obtained.Finally, single chip cooling lubricating oil system, the primary motor system
