JCYY01-009@单工位双面卧式车方组合机床的整体设计,机械毕业设计全套

内容简介：

河南理工大学本科毕业设计（论文） 1 摘 要 在普通机床上加工方头轴类 零 件，工作效率低、劳动强度大。当其零件有一定的批量要求时，其生产就显得力不从心了，为此设计了专用设备。 车方机床用曲率半径很大的椭圆短半轴曲线代替直线切削方形工件。生产率高 ,刀具成本低。选取适当的车头行星轮的分度圆直径 ,可以有效地控制车方原理的直线 度误差。对实际工件进行了原理误差的分析计算和行星轮系的设计计算。 本组合机床是针对 单 面 双工位 卧式 车削 的组合机床，在 完成 组合机床总体设计的基础上，主要完成 液压系统及滑台的设计 。在设计过程中借鉴了国内一些现有组合机床的设计资 料，结合被加工零件的结构特征， 在指导老师的帮助下设计而成 。进给部分采用液压滑台形式，主要是因为液压系统具有 工作比较平稳， 反应快、冲击小，能高速启动、制动和换向 ； 能在运动过程中实现无级调速，调速方便，而且调速性能好； 控制、调节比较简单，操纵比较方便，易于实现自动化，如与电气控制相配合，可方便地实现复杂的程序动作和远程控制 等优点。 关键词 : 车方 行星轮系 椭圆 方形 直线度 液压 nts 河南理工大学本科毕业设计（论文） 2 Abstract Process the square shaft parts on the common machine tool, inefficient and labor-intensive. When a certain amount for their parts, their production becomes unable, for the design of specialized equipment. It illustrates a ellipses short semi - axial curved line with great cured radius , that can replace the straight line for cutting square work - pieces on the machine tool. The productivity of this rebuilt machine tool is higher and the cost of cutter is lower. The principle straightness error of cutting square in work - pieces can be controlled by choosing a suitable pitch diameter of the planetary gear in the machine tools. Analytic calculations of the error and design of this train have been given for a real work -piece. This combination machine tools against unilateral double spaces horizontal turning combination machine tools, machine tool design in complete portfolio basis, the completion of the main hydraulic system and further Sliding workstations design. In the design process for some of the existing portfolio of domestic machine tool design data, the structural characteristics of the processed parts, with the help of teachers in guiding the design by. To the use of hydraulic slide into some form of Sliding workstations, mainly because of a hydraulic system work more stable, responsive, small shocks can speed up, brake and invert; And it can achieve infinitely variable speed control during the movement, speed control convenient, and the speed control performance is good; Controlling and regulating simpler, more convenient to manipulate, easy to automate, if compatible with the electrical control can easily achieve complex procedures, such as remote-contro
