【正文】 雜的是兩個通油孔的加工，分析知兩通油孔的尺寸和精度，表面粗糙度的要求是一樣的，只是其在零件上的位置不同而已。分析CA6140車床濾油器體的零件圖及其加工技術(shù)要求說明知，并且選用左端面為其它的待加工表面的定位基準(zhǔn),所以其加工過程是先以其粗加工為基準(zhǔn),待其它的加工完后再進行精加工，所以一般要采用粗銑，半精銑，精銑的過程才能滿足其要求。兩個通油孔的結(jié)構(gòu)看似簡單，但要達到其要求需要較多的加工工步，同時注意到兩通油孔的尺寸一樣。CA6140車床濾油器體的結(jié)構(gòu)屬于中等復(fù)雜的零件，總共有六個孔需要加工，而且三個螺栓孔的加工精度一般，只需要保證三個螺栓孔的位置精度即可。這就對濾油器提出了更高的要求。為實現(xiàn)上述的幾個精確控制，必須提高供油泵和濾油器的可靠性?；诟呔葹V紙對機床使用壽命和水對高精度濾油器使用壽命影響的試驗研究，提出現(xiàn)代機床的濾油系統(tǒng)應(yīng)采用兩級過濾，第一級應(yīng)由油水分離器和油粗濾器組成，第二級應(yīng)由高精度的濾紙承擔(dān)油精濾的任務(wù)，以滿足絕對過濾精度小于3μm的要求。由于能力所限，經(jīng)驗不足，設(shè)計中還有許多不足之處，希望老師雅正。這次畢業(yè)設(shè)計中，我所選的零件是“CA6140車床濾油器體”，完成該零件的機械加工工藝規(guī)程的編制及工藝裝備的設(shè)計，濾油器在車床上是個必不可少的部件，它有著過濾油液及緩沖的作用。三、進一步培養(yǎng)學(xué)生識圖，制圖，運算和編寫技術(shù)文件等基本技能。其目的主要有一下三點：一、培養(yǎng)學(xué)生運用機械制造工程學(xué)及相關(guān)課程（工程材料與熱處理，機械設(shè)計，公差與技術(shù)測量等）的知識，綜合生產(chǎn)實習(xí)中學(xué)到的實踐知識，獨立地分析和解決零件機械加工工藝問題，初步具備設(shè)計一個中等復(fù)雜程度零件的工藝規(guī)程的能力。 ponents。s machinery industry. 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。本課題以CA6140濾油器作為研究對象，綜合考慮濾油器的的制造成本和運行效率的雙重因素，對其進行工藝設(shè)計。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。一件成品是否實用，我們主要從兩個方面著手考慮，第一是技術(shù)是否先進，第二是經(jīng)濟是否合理。本論文主要討論CA6140車床濾油器體零件加工工藝。XUA回油濾油器屬于精過濾器，其結(jié)構(gòu)簡單，過濾精度高，具有濾心污染發(fā)訊器與油路旁通閥，可以很有效的提高液壓系統(tǒng)的可靠性。 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。濾油器一般可分為吸油濾油器和回油濾油器兩類。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。在系統(tǒng)中安裝一定精度的濾油器，是保證液壓系統(tǒng)正常工作的必要手段。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。 目前使用的WU式吸油濾油器屬于粗過濾器，其結(jié)構(gòu)簡單、通油能力大阻力小，具有濾心污染發(fā)訊器與油路旁通閥，提高液壓系統(tǒng)的可靠性。[1] 由此可見，濾油器在當(dāng)今機械行業(yè)中的重要性。它位于車床主軸箱上面，主要作用是給主軸箱內(nèi)供油及對油液起過濾作用，零件的兩端有兩孔用于油液的進出，零件的中間有一個外圓柱面，用于與主軸箱以基軸制形式聯(lián)接。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?？梢哉f一個不具有先進濾油器生產(chǎn)技術(shù)水平的國家，很難說是一個擁有了先進制造技術(shù)的國家。【關(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 impor
