摘 要
制造業(yè)中尤其是機械制造業(yè)，在產(chǎn)品生產(chǎn)過程中按照特定工藝，不論其生產(chǎn)規(guī)模如何，都需要種類繁多的工藝裝備，而制造業(yè)產(chǎn)品的質(zhì)量、生產(chǎn)率、成本無不與工藝裝備有關。隨著不規(guī)則形狀零件在現(xiàn)代制造業(yè)中的廣泛應用，如何保證這類零件的加工精度就顯得尤為重要。本文通過分析割草機齒輪箱頂蓋零件的結(jié)構特點和加工要求，制定了一套較合理的夾具設計，從而為保證該零件的加工精度將提供一種經(jīng)濟實用的工藝裝備，具有一定的實用價值。對于夾具設計來說，最重要的就是定位、夾緊方案的確定。針對割草機齒輪箱頂蓋這個零件加工要求的特點，確定了只能用平面定位、圓柱夾緊的辦法來加工該零件。通過對各種定位夾緊裝置的分析比較，選擇并組合了一套既能夠滿足加工要求的，又比較簡潔的裝置。同時，通過對一系列定位誤差和夾緊力的計算，驗證了該零件的加工是可以保證其要求的精度的，它的加工誤差在規(guī)定的范圍內(nèi)。通過夾緊力的計算，也驗證了零件在被夾緊的前提下，它受到的夾緊力也并不大，滿足夾具設計所要求的既要保證一定的夾緊力不使工件在加工過程中發(fā)生位移，但同時又不能過大致使工件發(fā)生變形。
關鍵詞：工藝裝備，夾具設計，定位，夾緊
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.
