摘 要

Ｓ195柴油機(jī)加工精度要求高,特別是機(jī)體氣缸套孔止口深度公差,大跨度等直徑同軸孔、平衡軸孔孔徑公差,大懸臂氣缸孔孔徑公差,曲軸孔與氣缸孔垂直度,曲軸孔與平衡軸孔、曲軸孔與凸輪軸孔軸心線平行度,氣缸套孔止口面與氣缸孔軸心線垂直度等的精度要求較高。機(jī)體加工中,精鏜孔工序的加工質(zhì)量將直接影響柴油機(jī)的功率、油耗、噪聲等性能。同時(shí),由于Ｓ195柴油機(jī)的生產(chǎn)批量較大,因而要求該工序的加工設(shè)備具有較高的生產(chǎn)效率和自動化程度。然而,目前國內(nèi)現(xiàn)有的加工設(shè)備都不能很好地滿足上述加工質(zhì)量和生產(chǎn)效率等方面的要求,這在一定程度上制約了Ｓ195柴油機(jī)的性能保證和生產(chǎn)產(chǎn)量的提高。作者設(shè)計(jì)的Ｓ195柴油機(jī)機(jī)體三面精鏜孔組合機(jī)床,是在調(diào)研的基礎(chǔ)上,吸收了鏜床設(shè)計(jì)的優(yōu)點(diǎn),根據(jù)具體情況設(shè)計(jì)、制造而成,如投入生產(chǎn)連續(xù)使用,將會獲得滿意的效果。

Abstract

S195 diesel engine expects machining accuracy much, especially organism air cylinder sets of hole stop mouthfuls of degree of depth public errand, Diameter, shaft hole, balanced shaft hole aperture public errand, such as large span,etc., big cantilever air cylinder hole aperture public errand , The shaft hole of song and air cylinder hole vertical degree, shaft hole of song and balancing the shaft hole, shaft hole of song and shaft hole of cam axis line parallel degree, Air cylinder sets of hole stop and expect relatively much with air cylinder hole axis line precision of vertical degree,etc. the mouth. In the organism is processed, the processing quality of the precise bore hole process will influence the performance, such as power, oil consumption, noise of the diesel engine,etc. directly . Besides, because the production lot of S195 diesel engine is relatively old, require the processing equipment of this process to have higher production efficiency and automatic degree. However, the domestic and existing processing equipment can't well meet the above-mentioned requests for processing the quality and production efficiency,etc. At present, This restrain S195 performance of diesel engine from guaranteed and produces the improvement of the output to a certain extent. Three precise bore holes of organism of S195 diesel engine designed now make up the lathe , it is on the basis of surveying and study, Have absorbed the merit that the boring machine is designed, succeed according to concrete conditions design and manufacture, Such as putting into production using in succession, will obtain the satisfied result .
