i摘 要?dú)飧左w是發(fā)動(dòng)機(jī)的主體，它將各個(gè)氣缸和曲軸箱連成一體，是安裝活塞、曲軸以及其他零件和附件的支承骨架。氣缸體的工作條件十分惡劣。它要承受燃燒過(guò)程中壓力和溫度的急劇變化以及活塞運(yùn)動(dòng)的強(qiáng)烈摩擦。氣缸套是柴油機(jī)的重要零件，內(nèi)孔加工是氣缸套生產(chǎn)過(guò)程中的一道重要工序，突破內(nèi)孔加工夾具的傳統(tǒng)設(shè)計(jì)思想，采用新型的內(nèi)孔加工夾具，闡明該夾具的設(shè)計(jì)原理和方法。本設(shè)計(jì)以柴油機(jī)汽缸套為例，對(duì)汽缸套的夾緊定位及其工藝過(guò)程和夾具的設(shè)計(jì)。在對(duì)汽缸套的工藝規(guī)程采用兩銷一面對(duì)其進(jìn)行定位以限制其六個(gè)自由度。為減少汽缸套在加工過(guò)程中的誤差，我考慮基準(zhǔn)的重合原則，統(tǒng)一原則，互為基準(zhǔn)原則以及粗基準(zhǔn)的選擇原則，為使定位夾緊可靠，要求所用的粗基準(zhǔn)盡可能不重復(fù)使用原則。詳細(xì)闡述了汽缸套的加工工藝過(guò)程，對(duì)加工過(guò)程中進(jìn)行的各道工序進(jìn)行了詳盡的說(shuō)明，并附有零件圖，加工工藝過(guò)程卡等資料加以說(shuō)明，使汽缸套的加工過(guò)程一目了然。關(guān)鍵詞：汽缸套 工藝規(guī)程 夾具iiAbstractAn is foundation spare parts that machine that keeping with parts, it machine with have the spare parts conjunction in the parts a the whole, and make right mutually position, complete the essential sport.Therefore, the a processes the quantity to affect the function of the machine directly, accuracy with life span.A spare parts though each of shape, the size is different, but they all have the cavity, the construction is complicated, thick not on an equal footing common characteristics in wall, on a wall the higher bearings in current and many accuracy props up the peaceful in bore demand processes, having again the lower and tight in a lot of accuracy bore demand process.Therefore, the difficulty that a not only need the part that process many, but also process is bigger too.This design controls with the CK6142 number the lather principal axis a number for example, detailedly expatiating a controls to process the craft process, in the process to process the each work preface that proceed proceeded in details of elucidation, and fish-eye spare parts diagram, work preface Chien's diagram, the number controls the machine bed processes craft Chien's card, the number controls to process the work preface card, the knife has card and numbers control to process the procedure, entering to take into the route diagram etc. data the assistance explain, making a box of process the process to is clear at a glance.Keywords: Cylinder，Process planning，F(xiàn)ixture
