设计简介
摘 要
本次设计名为专用数控铣床自动进出料系统设计，从研究数控铣床加工中心工作台入手，借鉴国内外先进经验，设计了一个适合与加工中心工作台匹配的自动进出料装置，完成具有动作快速、定位准确以及可以长时间连续作业等优点的自动进出料装置设计，满足了生产和设计的需要，主要设计包括一套专用夹具、输送机构等主要部件。
认真了考虑“实用、安全、经济”等各项因素，进行必要的方案计较后，最终确定最佳方案为专用夹具选用了电动装置作为夹紧装置，设计了压杆及内外压板进行工件的夹紧、定位。输送机构选用了机电装置，采用了步进电机、滚动直线导轨、滚珠丝杠螺母副和联轴器等进行工件的自动进出料。
设计主要进行了与加工中心工作台匹配的输送机构自动进出料装置以及专用夹具的结构设计，并进行了分析。论述了采用步进电机、滚动直线导轨、滚珠丝杠螺母副以及电动夹紧装置的优点。详细介绍了主要部件的结构设计过程及相关的计算校核。另外汇总了有关技术参数。
