牛头刨床的毕业设计正文_精品.doc

摘 要 牛头刨床是用刨刀对工件的平面、沟槽或成形表面进行刨削的直线运动机床使刀具和工件之间产生相对的直线往复运动来达到刨削工件表面的目的。使用刨床加工，刀具较简单，生产率较低（加工长而窄的平面除外），主要用于单件小批量生产及机修车间MATLAB；仿真 ABSTRACT Shaper of workpiece with knives plane, groove or forming surface cutting machine tools, the linear motion of the cutting tool and workpiece to between the linear reciprocating motion relative to achieve the purpose of cutting surface of workpiece. Use shaper processing, machine structure and simplistic, but productivity tools with lower (processing long and narrow plane except), mainly used for single piece and small batch production and to tinker workshop, therefore shaper optimization design of mechanism and research has the vital significance. In order to ensure structural parameters and motion parameters of different shaper, namely the motion characteristics in cutting planer knives for machining process of constant movement which close to guarantee the machining quality and extend the life of cutter, and tool hurry back to performance so as to raise productivity, such problem if can through designing a model platform, then just change parameter can solve the anticipated problems of the, this will greatly improve the design efficiency. This paper it is through the establishment of mathematical model of shaper institutions, then use MATLAB design a man-machine interactive graphic interface, and will mathematical model parametric, just change the structure of shaper parameters can be convenient realize movement analysis and movement simulation, can image directly observed the shaper trajectory, speed change and acceleration change rule. Keywords: shaper; Motion analysis; MATLAB; simulation 目 录 第1章 绪论……………………………………......................................1 1.1 本课题的研究目的与任务….......……………..……………….….......1 1.2 本课题的研究意义....………….…………….……………….….….….2 1.3 牛头刨床的发展现状简介…..………………………………...…...…..2 第2章 牛头刨床的基本工作原理……………………..................…5 2.1 刨床的介绍………………………………………………………...……5 2.2 牛头刨床的组成及基本结构………..……………………..…..…...….6 2.3 牛头刨床的基本工作原理………..…
