摘要
本设计主题是一种用于机车轴承座自动装卸的特殊机制。工业水平日渐上升并不断提高,工业生产趋于自动化。,解放人力的同时又带来许多机遇,在这个阶段,自动化生产显然已经成为人类追求的目标,并且现在已经慢慢实现,出来了许多机器人,如汽车加工中的机械手,本次设计也是一类机械手机器人,主要作用于机车轴承座生产中实现工件的自动上下料,翻转等一系列的动作,在加工过程中实现自动化生产。
本次设计的过程中所要完成的任务很多,要绘制该机械手的总体装配图及部装图和非标零件图,同时还要整理所设计部分的计算说明书。
设计时,首先要选择机械手的驱动方式,这里我选择液压系统驱动,因为该机械手是4自由度的机械手,4个自由度分别为夹紧/松开,升降和回转。因此,夹紧液压缸,提升液压缸和旋转液压缸的设计。
所以该机械手不但满足这4个自由的动作,它还可以确保可靠抓取,平稳灵活的传送以及准确的定位。同时还要进行液压系统的简单设计,液压系统的优势非常明显,体积小,重量轻;高刚性,高精度和快速响应;驱动力大,适合直接驱动重物;速度范围宽,速度控制方式多样;自润滑,自冷却,寿命长;容易实现安全保护。
设计的目的是在满足要求的前提下尽可能的符合实际的工作情况和安全情况,在工作车间的工作状况会导致某些动作的危险,还要考虑到机械手的成本,所以要从结构设计和运动学分析上解决问题,以实现本次设计的最终要求。
