摘 要
本文主要論述了柴油機(jī)連桿的加工工藝及其夾具設(shè)計(jì)。因?yàn)檫B桿是活塞式發(fā)動(dòng)機(jī)的主要零件之一,其大頭孔與曲軸連接,小頭孔通過(guò)活塞銷(xiāo)與活塞連接,其作用是將活塞的氣體壓力傳送給曲軸,又受曲軸驅(qū)動(dòng)而帶動(dòng)活塞壓縮汽缸中的氣體。連桿承受的是沖擊動(dòng)載荷,因此要求連桿質(zhì)量小,強(qiáng)度高。所以在安排工藝過(guò)程時(shí),按照“先基準(zhǔn)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(jié)合面及螺栓孔定位面。在夾具設(shè)計(jì)方面也要針對(duì)連桿結(jié)構(gòu)特點(diǎn)比較小,設(shè)計(jì)應(yīng)時(shí)應(yīng)注意夾具體結(jié)構(gòu)尺寸的大小等,最終就能達(dá)到零件的理想要求!

1、針對(duì)現(xiàn)有的連桿存在的強(qiáng)度、剛度不足、生產(chǎn)工藝復(fù)雜等問(wèn)題,根據(jù)連桿工作原理,提高夾具的制造精度,減少配合間隙并改進(jìn)加工工藝流程。

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!
This design research contents and innovative work is as follows:
1. In view of the existing strength and rigidity of the connecting rod is insufficient, complex production process and so on, according to the working principle of connecting rod, improve the manufacturing precision of the fixtures, reduce fit clearance and improve the machining process.
2. In view of the existing connecting rod set of fatigue fracture and hit, choose high carbon microalloy non quenched and tempered steel C70S6 and carburizing and quenching and tempering and annealing heat treatment.
3. In order to improve the production efficiency of the whole process, in the technology to ensure the positioning clip matter sum parts requirements under the premise of the jig also give full consideration to the choice of certain economy.
