摘 要
制造业中尤其是机械制造业，在产品生产过程中按照特定工艺，不论其生产规模如何，都需要种类繁多的工艺装备，而制造业产品的质量、生产率、成本无不与工艺装备有关。随着不规则形状零件在现代制造业中的广泛应用，如何保证这类零件的加工精度就显得尤为重要。本文通过分析割草机齿轮箱顶盖零件的结构特点和加工要求，制定了一套较合理的夹具设计，从而为保证该零件的加工精度将提供一种经济实用的工艺装备，具有一定的实用价值。对于夹具设计来说，最重要的就是定位、夹紧方案的确定。针对割草机齿轮箱顶盖这个零件加工要求的特点，确定了只能用平面定位、圆柱夹紧的办法来加工该零件。通过对各种定位夹紧装置的分析比较，选择并组合了一套既能够满足加工要求的，又比较简洁的装置。同时，通过对一系列定位误差和夹紧力的计算，验证了该零件的加工是可以保证其要求的精度的，它的加工误差在规定的范围内。通过夹紧力的计算，也验证了零件在被夹紧的前提下，它受到的夹紧力也并不大，满足夹具设计所要求的既要保证一定的夹紧力不使工件在加工过程中发生位移，但同时又不能过大致使工件发生变形。

Design of the Top Cover of the Gearbox
ABSTRACT
In the manufacturing industry especially for mechanical manufacturing industry, it is need the various-style craft in the course of production regardless of its production scale.Because it has close relation to the quality , productivity and cost in the whole production process. With the wide application of the irregular form part in the modern manufacturing industry, how to guarantee the machining accuracy of this kind of part seems particularly important. Through analysing the top cover part of hay mover and processing demanding of the top cover part of hay mover of the gearbox,a jig which has reasonable characteristic has been designed.It can not only guarantee the machining accuracy of this part for a kind of economical and practical craft equip and it also has certain practical value. To design of the jig , the most important thing is to make a scheme of reservation and clamp.As for the process demand of this part of top cover of the hay mover gearbox, through comparing of various kinds of reservations and clamps,a not only can satisfy with the demand of manufacturing and also very compactible device had been designed.
