1020-柴油機齒輪室蓋鉆鏜專機總體及主軸箱設計,柴油機,齒輪,室蓋鉆鏜,專機,總體,整體,主軸,設計 鹽城工學院畢業(yè)設計說明書 2006柴油機齒輪室蓋鉆鏜專機總體及主軸箱設計摘 要：本課題設計一臺加工柴油機齒輪室蓋的鉆鏜組合機床，主要完成機床總體和右主軸箱的設計工作。根據(jù)柴油機齒輪室蓋的結構特點、加工部位、尺寸精度、表面粗糙度及生產率等要求，確定該機床為單工位臥式組合機床；為確保加工精度，采用“一面兩銷”的定位方案；為實現(xiàn)無級調速，安全可靠，選擇液壓滑臺；根據(jù)零件的大小及被加工孔的位置確定主軸箱的輪廓尺寸；由加工工藝選擇滾珠軸承主軸，通過計算扭矩確定主軸和傳動軸的直徑；齒輪的模數(shù)是通過類比法確定； 齒輪齒數(shù)和中間傳動軸的位置是由“計算、作圖和多次試湊”相結合的辦法確定；計算主軸、傳動軸的坐標并進行中心距驗算，確定部分軸上需采用變位齒輪；軸上的齒輪套、鍵等零件按軸號選取相應的標準件。本課題設計的組合機床采用“一面兩銷”定位、液動夾緊，一次裝夾加工柴油機齒輪室蓋三個面上的孔，保證了加工精度，提高了生產效率，減少了工人的勞動強度。而且在設計之中，盡量選用通用件，減少了制造成本，增加了經(jīng)濟效益。關鍵詞：組合機床 主軸箱 主軸 傳動軸 齒輪室蓋鹽城工學院畢業(yè)設計說明書 2006The overall and headstock design of drilling and boring modular machine for diesel engine geal chamber manufactureAbstract: This project is to design a modular machine tool for manufacturing the gear chamber cap of diesel engine. Mainly work is the design of overall and the right headstock. According to the request of construction features, processing spot, size precision, surface roughness and productivity that diesel engine gear chamber cap, sets the machine tool for single location horizontal type modular machine tool. In order to guarantee the processing precision, the localization plan use "two sells and a surface". In order to implement the stepless speed regulation, safe is reliable, therefore choice hydraulic pressure sliding table. According the size of components and the position of the hole that is processed to set the overall size of the headstock. Choicing ball bearing spindle by processing craft. The spindle and drive shaft diameter is decided through computation torque. The gear modulus is decided through the correlation method. The gear mentions and the position of intermediate propeller shaft is decided by the means " computation, mapping and tries to collect many times". Calculates the coordinates of the spindle and drive shaft and checking the center distance, determined department spindle must use dislodges the gear. The components of tooth wheel cover, key and so on that in axis select standard letter by the corresponding number. The modular machine tool of this project design use “two sells and one surface” to locate , hydraulic press and clamps. In the situation of one clamp, the holes three surface of the diesel engine gear chamber cap, are guaranteed the processing precision, is enhanced the production efficiency, is increased worker's labor intensity. Moreover during the design, the standard parts are selected as far as 鹽城工學院畢業(yè)設計說明書 2006possible, reduced the production cost and increased the economic efficiency.Key words: modular machine tool headstock spindle drive shaft gear chamber cap
