AD喷涂机的设计 机电041：聂文喜 指导老师：祁广利 （陕西科技大学职业技术学院 陕西 西安 710021） 摘要：根据显像管AD喷涂的工作要求,研制了一种集机电气为一体的AD喷涂机,采用凸轮—连 构和可编程序控制器实现喷涂过程的自动化,整机结构紧凑、性能稳定、调整方便。 本次主要设计内容：AD机的设计大体可以分为机械部分的设计和控制部分的设计。本设计 要以AD机的机械部分设计为主要设计内容。机械部分的设计，以电机为原动件。传动部分以齿轮减速和蜗轮蜗杆减速为传动件。执行部分是一个凸轮连杆机构带动的四滑块机构，滑块上带有含有两个料斗的喷枪。除了机械部分以外还对控制部分做了简单的设计，控制部分是通过变频器在PLC的控制下实现的。 关键词:喷涂机，变频器，凸轮—连杆，可编程序控制器 ThedesignofADsprayingmachineofcolorpicturetube Abstract ：According to develop to take care of the work request that the AD sprays to draw, research to manufacture a kind of gather the machine electricity as integral whole of AD spray to draw the machine, the adoption cam- connect the automation that the pole organization and the programmable preface controller realizations spray to draw the process, the whole machine structure tightly packed, the function stability, the adjustment convenience. This time mainly designs the contents:The design big body of the AD machine can is divided into the design of the machine part and the design of the control parts.This design mainly with the machine part of the AD machine design for mainly design the contents.The design of the machine part, take electrical engineering as to move the piece at first.Spread to move the part with the wheel gear decelerates to decelerate with turbine pole for spread to move the piece.The The performance part is a cam to connect the pole organization to arouse of four slippery organization, slip the piece to take to imply two air guns that anticipate the up.Returned to did the simple design to the control part in addition to the machine part, the control part pass to change the machine of in the PLC of control under realization.
