本科毕业论文（设计） X6132型万能升降台铣床长齿条铣削功能扩展的设计 *** 2013 1*00** 专 业 名 称 机械设计制造及其自动化 申请学士学位所属学科 工科 指导教师姓名 、职称 （教授） 20 年 月 日 摘 要 长齿条由于尺寸太长而无法在通用设备上加工 ,改装有齿装置的型床可同时加工几根齿条 ;万能升降台铣床是一种通用金属切削机床。机床的主轴锥孔可直接或通过附件安装各种圆柱铣刀、成型铣刀、端面铣刀、角度铣刀等刀具，适用于加工各种零部件的平面、斜面、沟槽、孔等，是机械制造、模具、仪器、仪表、汽车、摩托车等行业的理想加工设备但是缺点主要是机床，些有的工件无法加工。机床设计本身没有多少缺点，铣刀 Abstract The multi-layered hot press is the production plywood, the shaving board, building board and so on density fiberboard major installations. At present the equipment factory productions hot press has finalized basically, to improve hot presss structure performance and reduce the production cost, this article mainly has carried on the design to five side thrust type hot press structure, and to hot presss important part under carriers structure, the intensity and the rigidity has carried on the project analysis and calculates, causes the carrier to be more reasonable in the structure, reduced the material and the energy consumption, raised the productivity. The design main union existing design idea, in conforms to under the design requirements premise, in the design in presss rack whole has mainly used the steel plate welding closed type rack, this kind of structure manufacture convenience does not need the large-scale processing equipment, and, the selection has mainly used the I-steel, the angle steel and so on commonly used material, uses processing craft which the steel plate welds, thus, the production technology capability is good, generally the machine shop can make. In the design has mainly used CAD, engineering drawing soft wares Pro \ E and so on, used the software Pro \ E to carry on the stress analysis. 窗体顶端 Key words: lateral pressure type, thermal-pressing machine, structural design, stress analysis 窗体底端 1.引言 长齿条是现代各种机床的主要部件之一 。它的生产能力和制造精度决定了现代工业的生产能力，而长齿条由于尺寸太长而无法在通用设备上加工, 虽没有专门的长齿条加工的通用设备, 但我们通过对通用设备的改造、革新后, 照样可以生产出满足加工精度要求的长齿条. 大量的
