PDP砂轮机的研发创新设计

A creative design of PDP grinder

对PDP生产装备中的砂轮机进行了功能分析,在此基础上重点阐述了国产化过程中的突破点:第一因砂轮是消耗件,需求量大,必须自主创新,逐一对其结构形式、动平衡品质等级、砥粒种类、磨料粒度、结合剂代号和浓度等进行了国产化设计,同时还创新地使其具有可修复性的特点;第二是砂轮主轴,为确保加工产品(玻璃)的合格率,砂轮主轴须具备自适应浮动结构,轴向自适应通过滚珠花键来实现,而径向自适应则通过阻尼气缸来实现;第三保证了PDP生产环境的高洁净度要求,采用封闭式磨削环境和负压(发生器)吸尘排污双重工艺措施,达到了理想的净化效果。

The grind mill in PDP produce equipment is been analysised in the paper,Based on it the breakthrough-point in homemade-prcoess is been emphasized,first on,self-innovation of grind wheel is necessary as it is expendable supplies and macro-needed.The structure style,move-balance character grade,sand granularity,type of agglutinant and concentration is been homemade contrived seriatim,and make it have the repairable trait innovatively,Second,the main axle of grind mill must have self-adjustable float structure to ensure the eligibility of product.Axis-direction self-adjustable is actualized using rolling ball splines,radius-direction self-regulate is actualized using damp-cylinder.Third,through closed milling-condition and vacuum generator with double technique of dust absorbing and dirt evacuating ensure the high lustration of PDP produce-condition and get a satisfying result of eligibility.
