基于三維的柴油機氣缸蓋組合鉆床總體及后主軸箱設計
摘 要:組合機床是根據(jù)工件加工需要,以大量通用部件為基礎,配以少量專用部件組成的一以及種高效的專用機床。組合機床一般采用多軸、多刀、多工序、多面或多工位同時加工的方法,生產(chǎn)效率比通用機床高幾倍至幾十倍。本課題設計的是臥式三面鉆孔組合鉆床,來源于鹽城市江淮動力集團。柴油機氣缸蓋是需要大量生產(chǎn)的零件,為了提高加工精度和生產(chǎn)效率,需要設計一種組合機床來改善柴油機氣缸蓋的加工情況。該設計的內(nèi)容包括總體設計和后主軸箱設計。在總體設計中分析了被加工零件的加工工藝性,選擇了加工的定位基準及加緊方案等,同時完成了“三圖一卡”的繪制。在后主軸箱設計方面,首先確定繪制后主軸箱設計原始依據(jù)圖,接著對主軸結(jié)構型式選擇和動力的計算,然后對主軸箱傳動系統(tǒng)進行設計與計算,在對后主軸箱中的傳動軸直徑和傳動軸在箱體中的位置進行計算,最后對軸和齒輪的強度進行校核,繪制出主軸箱中傳動軸坐標檢查圖。本組合機床效率高,成本低,加工精度高,操作使用方便,減輕了工人的勞動強度,提高了勞動生產(chǎn)率,滿足了設計需要。

Based on the 3D engine cylinder head and the overall portfolio after the drilling spindle box desig
Abstract: The combination of machine parts processing is based on need, to a large number based on common components, supported by a small number of dedicated components of a highly efficient and dedicated machine.The general composition of multi-axis machine tools, multi-tool, multi-process, multi-faceted public place or method of processing at the same time, production of high-efficient than GM machine several times to 10 times. This design is the subject of horizontal drilling combination of drilling on three sides, the impetus comes from Yancheng Jianghuai Group. Diesel engine cylinder head is the need to mass-produced parts, in order to increase production efficiency and accuracy of processing, machine tools needed to design a combination of diesel engine cylinder head to improve the processing conditions. The design will include design and post-spindle box design. In the overall design of the processing parts of the processing technology, select the location of the processing base and intensify their programmes, and completed a "three-card plans a" mapping. After the spindle box in the design, the first set after drawing spindle box design based on the original map, then the main structure of the power and choice, then the spindle box drive system design and calculation, in the main shaft after me in the drive shaft diameter And the transmission shaft in the box in the location, the last of the gear shaft and the strength of Verification, to map out spindle box in the drive shaft inspection map coordinates. The combination of machine high efficiency, low cost, high-precision machining, easy operation, reducing the labor intensity of the workers, increased labor productivity, and meet the needs of the design.
