机床主轴箱结构设计(含CAD零件装配图)(任务书,设计说明书12000字,CAD图纸3张)
摘要
车床是机床中应用最广泛的一种，约占车床类总数的65%，因其主轴以水平方式放置故称为卧式车床。主传动系统的运动设计有确定极限转速、确定公比、确定转速级数、确定结构网和结构式、绘制转速图、确定齿轮齿数和拟定传动系统图。主运动部件的结构设计有：带传动的设计、确定各种计算转数、确定齿轮模数、确定各轴最小直径和设计部分主轴主件。设计完成后轴与轴承的校核：轴的校核主要通过轴颈、结构、运动等计算出轴最大承受能力，能够正常工作的时间。轴承则通过与每个不同的轴的连接，确定要用的轴承，选出最好的轴承，最终确定轴承轴和轴承是否达到要求。
本文对机床床头箱进行了设计，的主轴箱是机床的动力源将动力和运动传递给机床主轴的基本环节，其机构复杂而巧妙，要实现其全部功能在软件中的模拟仿真工作量非常大。这次设计的效果没有预计的完美，有一些硬件方面的原因，在模拟仿真的时候，由于计算机的配置不能达到所需要求，致使运行速度非常慢，不但时间上拖了下来，而且所模拟的效果很不理想。我接受的设计任务是对车床的主轴箱进行设计。主轴箱的结构繁多，考虑到实际硬件设备的承受能力，在进行三维造型的时候在不影响模拟仿真的情况下，我省去了很多细部结构。

Abstract
Common lathe is one of the the most widely used, accounting for 65% of the total number of lathes , because of the spindle horizontally placed so called horizontal lathe.Mainspindle: also known as the headstock, its main task is coming from the main motor rotation speed through a series of institutions required for the spindle to be turned to different positive and negative speed, while spindle box allocate part of the power the campaign to pass into the box. Lathe headstock spindle is the key to the middle part. Spindle bearing on the smooth operation of the workpiece directly affect the processing quality, once the accuracy of the rotation decreased , the machine's using values .
feed box: also known as the cutting box, feed tank equipped with a variable speed feed motion in the body, it can adjust the speed to change mechanism, obtain the required feed rate or screw pitch, the light bar or screw through the spread of sports knife frame for cutting.Screw and light bars: to connect the feed box and the crates and deliver the motion and driving force to slide crate ,to make crate to get the vertical linear slide motion. Start lathe check each variable speed are in the lathe neutral. Clutch (clutch) whether is in the correct position, joystick is no in stop state, when confirmed, close the lathe total switch power supply. saddle bed according to the green button, motor (elettdc molor) started brought up to slip board box on the right side of the lever handle, spindle is turned; Lever handle back into the middle position, spindle stop turn move; Lever handle press, spindle reversal. the saddle bed of red stop button, motor stopped working.
Keywords: haft; gear; Spindle box;
