毕业设计(论文)网: QQ:306826066毕业设计说明书中文摘要 四柱液压车轮钻孔机的设计摘要 专用钻床实在普通机床的基础上，根据待加工工件或加工所处的特殊条件而设计制造出来的钻床。四柱式钻床的液压系统就是利用液压技术来控制动力滑块，机床可以在较大的范围内进行无级调速，具有良好的换向性能，且能够实现自动工作循环，从而提高效率。随着液压技术的发展，它在机床上的应用必将不断地得到扩大和完善。钻床是指主要用钻头在工件上加工孔的机床。通常钻头旋转为主运动，钻头轴向移动为进给运动。钻床结构简单，加工精度相对较低，可钻通孔、盲孔，更换不同刀具，可扩、锪孔，铰孔或进行攻丝等加工。关键词专用钻床 液压系统 钻床 钻孔毕业设计说明书外文摘要Design of the Four-column hydraulic wheel drilling machineAbstract Special drill press really common machine tools, and on the basis of machining or processing according to stay in the special conditions and the design is made out of the drilling machine. Four pillar type hydraulic system of drilling machine is using the hydraulic technology to control the power slider, the machine can be performed within In a larger scope of stepless speed regulation, it has good performance of commutation, and can realize automatic cycle work, improve the efficiency . Along with the development of hydraulic pressure technology, it will expand and improve constantly in the application of the machine. Drilling machine is mainly used to drill holes in the processing of machine. Usually, the drill bit rotation movement as a main movement, and the move in the direction of the axis as a Feed movement. The structure of the drill is simple and its processing precision is low ,it can drill through-holes, blind via, after changing different cutting tools, it can reaming and countersinking, it also can be used to tapping screw.
