摘 要
本文主要論述了柴油機連桿的加工工藝及其夾具設計。因為連桿是活塞式發動機和壓縮機的主要零件之一,其大頭孔與曲軸連接,小頭孔通過活塞銷與活塞連接,其作用是將活塞的氣體壓力傳送給曲軸,又收曲軸驅動而帶動活塞壓縮汽缸中的氣體。連桿承受的是沖擊動載荷,因此要求連桿質量小,強度高。所以在安排工藝過程時,按照“先基準后一般”的加工原則。連桿的主要加工表面為大小頭孔和兩端面,較重要的加工表面為連桿體和蓋的結合面及螺栓孔定位面。 在夾具設計方面也要針對連桿結構特點比較小,設計應時應注意夾具體結構尺寸的大小等,最終就能達到零件的理想要求!

Abstract
The diesel connecting rod treating handicraft the main body of a book has been discussed mainly and their grip design. Because of the connecting rod is one of dyadic engine of piston and main compression engine part, whose larger end hole and crank shaft link up , the small head hole links up by the wrist pin and the piston , whose effect is that the piston gas pressure is transmitted to the crank shaft , collect crank shaft gas in driving but setting a piston in motion to compress a cylinder. Being that the pole bears pounds a live load , request connecting rod mass is minor therefore , the intensity is high. Therefore when arranging procedure for, according to "first the criterion queen-like " treating principle. The connecting rod main part processes a surface being that head hole and both ends big or small are weak, more important faying face and bolt hole locating surface being the connecting rod body and cover treating outside. Also should be comparatively small specifically for connecting rod structure characteristic in the field of grip design , design that the size should pay attention to gripping the concrete structure dimension of the season waits, the ideal being therefore likely to reach a part ultimately demands!
