內容簡介：
摘要：本組合機床是氣缸蓋半精鏜、精鏜組合機床，在完成 “三圖一卡”的基礎上，主要完成夾具設計。這個課題來源於江蘇高精機電裝備有限公司，是為了適合流水線生產，提高目前的生產效率、加工精度，從而降低加工成本而設計的。在設計過程中借鑒了國內外一些現有的組合機床設計資料，還參考了一些與本課題相關的文獻資料。
設計的主要內容為組合機床的總體設計和夾具的設計。夾具的設計是本次設計中一個重要的部分。在夾具設計方面，首先，原有機床採用多工序加工，加工效率低，加工尺寸不容易保證，而且位置精度也不高。改進后，採用一次裝夾，同時對進氣和排氣孔進行鏜加工，提高了加工效率。其次,夾具採用一面兩銷定位，保證了導管孔及氣門閥座孔對定位銷孔的位置精度。夾緊方式採用液壓夾緊，改變了原來的手動夾緊，提高了工作的效率。最後，對相應部分進行了計算、分析、校核。
本組合機床具有提高生產效率，滿足工件的加工精度，減少了工人的勞動強度的優點，較好的實現了設計的要求。

Abstract: The modular machine-tool is defined as half finish and full finish boring machine with cylinder lids. In addition to the accomplishment of “Three drawings and one card”, the major task is to finish the design of jigs. The project originally from Jiangsu Gaojing Mechanical & Electrical Equipment CO.,LTD. Ltd aims to cater to the assembly line and improve effectiveness and processing precision so as to reduce the cost. During the process of design, I drew lessons from international and national data, and referenced some literature material related to the topic.
The designs cover the overall ones of the assembled machine and jigs. Firstly, as far as jig design, the main part of the designs, is concerned, the original machine tool has characteristic of multi working procedure machining, effectiveness, difficult machining size guarantee, and low location precision. After being improved, both the air inlet louver and outlet louver are bored by jigging just once, which not only improves effectiveness but also guarantees machining hole sizes. Next, in order to ensure the process precision and production efficiency of boring machine tool ,the jig uses ‘one surface-two sell’ .the way of Clamps is hydraulic pressure clamping, which replaced by Manual clamping. It can enhanced the work efficiency. At last, carry on the computation, the analysis, the examination to corresponding parts.
The advantages of this modular machine-tool are production efficiency, high precision of processing, reducing labor intensity of the workers.
Key words：modular machine-tool; jig; location; clamping
