TY495柴油機(jī)機(jī)體工藝及工裝設(shè)計(jì)
摘要： TY495柴油機(jī)以其設(shè)計(jì)緊湊,啟動(dòng)輕便,維修簡(jiǎn)便,技術(shù)經(jīng)濟(jì)指標(biāo)先進(jìn),能為手扶拖拉機(jī)、水泵、電站、運(yùn)輸及多種農(nóng)副業(yè)加工機(jī)械和設(shè)備作配套動(dòng)力,在工農(nóng)業(yè)生產(chǎn)中得到廣泛的應(yīng)用。 本設(shè)計(jì)要求“以質(zhì)量求發(fā)展，以效益求生存”在保證零件加工質(zhì)量的前提下，提高了生產(chǎn)率，降低了生產(chǎn)成本，是國(guó)內(nèi)外現(xiàn)代機(jī)械加工工藝的主要發(fā)展方面之一。通過(guò)對(duì)TY495柴油機(jī)機(jī)體零件圖的分析及結(jié)構(gòu)形式的了解從而對(duì)柴油機(jī)機(jī)體進(jìn)行工藝分析、工藝說(shuō)明和加工過(guò)程的技術(shù)要求以及精度分析。柴油機(jī)機(jī)體體在加工時(shí)要經(jīng)過(guò)粗銑、鏨、精銑、去毛、粗鏜、鏨、半精鏜、精鏜、鉆、鉸、割、攻絲等工，最后檢驗(yàn)入庫(kù)。然后再對(duì)機(jī)體的底孔、軸承孔的加工進(jìn)行夾具設(shè)計(jì)及誤差分析，該工藝與夾具設(shè)計(jì)結(jié)果能應(yīng)用于生產(chǎn)要求。

TY495 diesel engine organism craft and work clothes design
Abstract: TY495 diesel engine for its compact design, start light, easy maintenance, technical and economic indicators advanced for walking tractors, water pumps, power plants, transportation and a variety of agricultural and sideline processing machinery and equipment for motive power, industrial and agricultural production in the widely application. The design requirements of "quality development to benefit survival" in ensuring the quality of parts processed under the premise of improved productivity, lower production costs, is home to modern machining process one of the major development. By TY495 engine block parts diagram analysis and understanding of structure and thus on the engine block for process analysis, process descriptions and process and accuracy of the technical requirements. Engine block when the body in the process to go through a rough milling, engraving, milling, to the hair, coarse boring, chisel, semi-fine boring, precision boring, drilling, hinge, cutting, tapping and other workers, the final test storage. And then the bottom of the body, bearing holes for fixture design and machining error analysis, the results of the process and fixture design can be applied to production requirements.
