北京理工大学珠海学院 2020 届本科生毕业设计自动点胶机结构设计——整体机架设计自动点胶机结构设计——整体机架的设计摘 要本设计主要是对自动点胶机结构设计中的整体机架设计，设计的自动点胶机采用龙门式组合机架结构，整体机架由机架底座、左右两立柱、X 轴工作台、Y 轴工作台和 Z 轴工作台组成，机架的材料选用铸铝材料，在保证刚性、强度以及稳定性的同时考虑经济性和工艺性。设计的自动点胶机机械运动为，X 轴工作平台固定在立柱上不动，在机架底座上的 Y 轴工作台可实现前后移动，Z 轴工作台在点胶工程中进行上下移动，并且可以在 X 轴工作平台的导轨上实现左右移动。同时，X、Y、Z 轴方向上都设计了滚动丝杠和导轨，其机械运动为滚珠丝杠将步进电机中的旋转运动变为整个机构所需要的直线运动。关键词：机架、XYZ 轴、滚珠丝杠。北京理工大学珠海学院 2020 届本科生毕业设计Design Of The Whole Frame Of The Automatic DispenserAbstractThis design is mainly for the overall frame design in the structural design of the automatic dispenser. The designed automatic dispenser adopts a plate-type combined frame structure. The overall frame is composed of the machine plus a base, left and right columns, X-axis work table, Y The shaft table and the Z-axis table are composed. The material of the frame is cast aluminum, which ensures the rigidity, strength and stability while considering the economy and manufacturability. The mechanical movement of the designed automatic dispenser is that the X-axis working platform is fixed on the upright post, the Y-axis working platform on the base of the rack can move forward and backward, and the Z-axis working platform moves up and down in the dispensing project, and It can move left and right on the guide rail of the X-axis working platform. At the same time, rolling screws and guide rails are designed in the X, Y, and Z directions. The function of the ball screw is to be able to convert the rotating...
