论文题目:M7130B 平面磨床夹具的设计
摘要
本次毕业设计主要设计M7130齿条线平面磨床夹具,此夹具的优点是磨削精度高,能够进行不同零件的加工,即能加工各种柱形面有能加工各种平面工件,其应用范围非常广泛。这种夹具主要是利用磨头的上下运动和砂轮的圆周面进行磨削,砂轮的转速较高,圆周离心力也较大,当砂轮与工件的表面接触时,会瞬时磨出火花。本次设计的零件既为圆柱形工件,要求在圆柱面上利用M7130齿条线平面磨床磨出一个扇形面,其加工工序分为:首先在砂轮上先粗铣一个扇形槽,然后使扇形槽砂轮以一定的转速与圆柱形工件的表面接触,最后利用砂轮磨削工件。这样就可以加工出所需要形状的工件。总之通过本次设计,使我了解了M7130齿条线平面磨床夹具的组成部分及各部分所起的作用,从而使我明白了次家具的工作原理。

Abstract
This graduation designs a line of the main design M7130 flat surface grinding machine tongs, the advantage of this tongs is to whet to pare the accuracy high, can carry on different spare parts' process, can process various pillar form to face it can process various flat surface work piece, its application is very extensive. This kind of tongs mainly is top and bottom sport and the circumference of the emery wheels that makes use of to whet the head to face to carry on whet to pare, the emery wheel e soon higher, the circumference leaves the mental exertion to pare greatly, be the surface contact of the emery wheel and the work piece, will whet a spark in a moment. A spare parts for design since is the cylinder form work piece, request to face in the cylinder up make use of a line of the M7130 flat surface grinding machine to whet a fan-shaped side of, it processes the work preface to is divided into: First a fan-shaped slot of first thick on the emery wheel, then make fan-shaped slot emery wheel with certainly turn soon with the surface contact of the cylinder form work piece, make use of the emery wheel to whet to pare the work piece finally. Can process thus the work piece of the demand shape. In fine pass a design, make me understand a line of the M7130 flat surface grinding machine tongs to constitute the part of and each function that part rise, thus make me understand the work principle of a furniture.
Key words: Tongs, whet to pare the accuracy, work preface
