复合转台平面砂带磨床磨头结构设计（本科毕业论文设计）
摘 要
在砂带磨床的设计中，磨头是最关键的，它的主要零部件的制造精度，刚性的指标将对工件表面质量，加工精度有很大的影响。
现代机械工业中各种平面度要求高的平面加工，如汽车及摩托车离合器片、刹车盘、阀片、连杆端面；发动机箱体（箱盖）端面、曲轴箱体密封面、法兰盘端面；变速箱拨叉、五金工具双端面、块状零件双端面、齿轮端面等。若用传统的车削、飞刀铣削，甚至砂轮端面磨削，都存在成本高、效率低、易烧伤、翘曲变形，平面度及平行度难以保证等缺点。特别是盘状类薄金属零件和非金属零件，其本身存在自身薄、刚性差、易变形等特点，传统的加工方法很难满足其工艺要求。故本文设计一种新的加工方法——复合转台磨床加工，复合转台磨床主要用来加工薄片类零件，它以砂带作为磨削工具，采用复合回转台结构和压磨板磨削方式，在很大程度上减小了零件的受力和受热变形，并能在加工表面形成理想的磨削轨迹，因而可以达到较好的加工效果。
本文主要从磨头结构及手轮调节系统、进给机构、进给的平稳性等方面进行设计与优化。
关键词：砂带磨削，复合转台，压磨板，气缸，磨头进给机构
ABSTRACT
In the design of the belt grinder, grinding head is the most critical, the manufacturer of precision and the rigid targets of its main parts and components will have great impact on the surface quality, precision machining of workpiece.
Various plane processing with high flatness requirements in modern machinery industry, such as clutch,brakes, the valve, linkage End of cars and motorcycle; Engine Box (Covers) end, crankshaft box sealing surface, the flange end; Bocha gearbox,dual-end hardware, massive double-end components,gear End and so on.If use the traditional turning, Feidao milling, grinding and grinding wheel end processing will cause some shortcomings,such as high costs, low efficiency, easy to burn, warping deformation,and it is difficult to guarantee flatness and parallelism and so on. In particular disc type thin metal parts and non-metallic parts, they have characteristics of thin,rigid poor, vulnerable deformation and so on,so it’s difficult for the traditional method of processing technology to meet their demands. Therefore, this paper design a new processing methods - composite table grinder processing, complex table grinder mainly used for processing thin parts, it uses belt as a grinding tool, using composite turret structure and pressure plates grinding mill, in Part of a large extent reduce the heat stress and deformation of workpiece,and it can form an ideal grinding track in the process of surface,so it can achieve better results processing.
This article mainly design and optimization the grinding head structure and hand wheel-conditioning systems,feed agencies,stationary of the feed and so on.
