This paper focuses on the oil filter body parts CA6140 lathe processing. It is located above the lathe headstock, the spindle inside the main role is to play on the oil supply and filtration, there are two ends of parts for the oil and out of holes, a cylindrical middle part of the cylinder, used for axis spindle box system in the form of base connection. As we all know, in this era of all walks of life are involved in machinery, mechanical parts, like every invention, the production of both was extremely important, and processing technology as the middle of the bridge, it is bound is also very important. A finished product is useful, we mainly considered from two aspects, first, whether the technology is advanced, the second is whether the economy is reasonable. Processing technology as a basis for processing directly determine these factors. Oil filter part of a process as in the machinery industry, industrial clients, have to undertake highend and base end of the important role of industry, the technical level, on a country39。濾油器零件工藝作為機械行業(yè)的一個中端工業(yè)，有著承接高端和基端工業(yè)的重要作用，其技術(shù)水平高低，對一個國家的工業(yè)技術(shù)發(fā)展水平具有一定的代表意義。本論文主要討論CA6140車床濾油器體零件加工工藝。 回油濾油器用于液壓系統(tǒng)回油過濾，過濾液壓系統(tǒng)中由于元件磨損產(chǎn)生的金屬顆粒，心臟密封件產(chǎn)生的污染物，使流回油箱的油液保持清潔。摘 要液壓油中往往含有顆粒狀雜質(zhì)，會造成液壓元件相對運動表面的磨損、滑閥卡滯、節(jié)流孔口堵塞，使系統(tǒng)工作可靠性大為降低。吸油濾油器一般安裝在油泵的吸油口處，用以保護油泵和其他液壓元件，以避免吸入污染雜質(zhì)，可以有效的控制液壓系統(tǒng)的清潔度。[1] 由此可見，濾油器在當(dāng)今機械行業(yè)中的重要性。加工工藝作為進行加工的一個依據(jù)則直接決定這些因素?！娟P(guān)鍵詞】濾油器；零件；加工工藝AbstractHydraulic oil often contain particulate impurities, the relative movement of hydraulic ponents will cause the surface of the wear and tear, catching slide valve, throttling orifice plug, greatly reduced the reliability of the system work. Certain precision in the system installed oil filter is to ensure that the hydraulic system to work the necessary means. Oil filter oil filters and generally can be divided into two categories return filter. Oil filter is usually installed at the pump inlet to protect the pump and other hydraulic ponents, in order to avoid inhalation of contaminated impurities can effectively control the hydraulic system cleanliness. Return filter back to the oil filter for the hydraulic system, hydraulic system filter ponent wear due to metal particles produced by the heart of pollutants generated seal, so that the oil flow back into the tank clean. WU type currently in use are crude oil filter oil filter, and its simple structure, small resistance through a large oil capacity, with the sender filter pollution control and oil bypass valve to improve the reliability of the hydraulic system. XUA return to the oil filter oil filter is fine, its simple structure, high filtration precision, with the sender filter pollution control and oil bypass valve, can be very effective to improve the reliability of the hydraulic system. This shows that the oil filter in the importance of today39。 processing technology 目 錄前 言 1第一章 零件的分析及生產(chǎn)類型的確定 3 零件的作用 3 零件的工藝分析 4 零件的生產(chǎn)類型 4 本章小結(jié) 5第二章 零件毛坯的設(shè)計 6 6 防止濾油器零件變形的工藝措施 9 本章小結(jié) 9第三章 零件的加工工藝設(shè)計 10 10 定位基準(zhǔn)的選擇 10 10 制定工藝路線 11 工藝方案的比較與分析 13 機械加工余量、
