的抗彎 強(qiáng)度 保證 軸線的水平 。導(dǎo)套導(dǎo)柱要求既要耐磨,又要有足夠的任性。為增加表面硬度和耐磨性,我們要進(jìn)行表面淬火處理,滲碳層厚度為 ~,淬火后的硬度為 HRC58~HRC62。我們通過上述條件確定導(dǎo)套導(dǎo)柱的結(jié)構(gòu)如下: 導(dǎo)套的結(jié)構(gòu) 如下 圖 5— 10 所示 : 圖 5— 10 導(dǎo)套的結(jié)構(gòu) 黃 石 理 工 學(xué) 院 畢 業(yè) 設(shè) 計 論 文 24 導(dǎo)柱的結(jié)構(gòu) 如下 圖 5— 11/所示 : . 箱體設(shè)計 機(jī)構(gòu)的 箱體設(shè)計 不需要很復(fù)雜的設(shè)計,我們這里箱體為兩面開口的六面體,一面向上露天開口,一面向下用螺栓固定在底座上,箱體在我們的機(jī)構(gòu)中有安裝導(dǎo)柱用的孔并且要求比較高,因?yàn)閷?dǎo)柱要精確定位。還有就是定位擋銷的孔,精確度也比較高。其他沒有什么精度要求,在這里受力也不是很大,強(qiáng)度沒有什么太大的要求。 箱體我們采用灰鑄鐵 HT250 鑄造然后在對精確度要求高的部位加工即可。 設(shè)計總結(jié) 通過畢業(yè)設(shè)計,我鞏固了三年來所學(xué)的知識, 此次設(shè)計雖和我們的專業(yè)并不有很大的關(guān)系,但是這也是我們機(jī)械類專業(yè)應(yīng)該了解的 知識應(yīng)該擴(kuò)展學(xué)習(xí)的內(nèi)容,這樣我可以更加有效的提高我對工作性質(zhì)的了解及如何去應(yīng)用與把握。此次設(shè)計我 對機(jī)械設(shè)計過程有了一個比較完整的認(rèn)識和了解,并系統(tǒng)的掌握了機(jī)械設(shè)計的過程和方法。 至于本次的設(shè)計,因?yàn)槭鼙旧淼乃季S和知識水平限制,導(dǎo)致設(shè)計中很少有創(chuàng)新之處。雖然成果不是很令人滿意,但終究是自己動腦動手一步一步做出來的,這點(diǎn)使我在遺憾之余感到些許欣慰。在設(shè)計中的每一步,我都做了認(rèn)真的考慮,在這樣點(diǎn)滴考慮與思量過程中,我摸索到一些關(guān)于機(jī)械設(shè)計 的 方法 和經(jīng)驗(yàn) ,更清晰 的 了解 了 整個設(shè)計過程。 此設(shè)計是我在大學(xué)里完成的最后一份 作業(yè),覺得不同尋常。因?yàn)檫@是結(jié)束,所以又意味著開始。只不過結(jié)束很倉促,而開始又緩緩未來。于是我期待著,企盼著,我必須把這次設(shè)計完成好,以證明自己有能力出去面對社會,能在社會中有所作為。 由于未從事過實(shí)際的機(jī)械設(shè)計,有很多參數(shù)資料都來源于參考書籍,再加上沒有實(shí)際工作經(jīng)驗(yàn),所以疏漏錯誤百出, 難免有不祥的地方和出錯不合理的地方, 還請各位前輩師長指出原諒,學(xué)生感激不盡! 相信本人在以后的工作過程中,理論結(jié)合實(shí)踐,經(jīng)過不懈的努力,在本專業(yè)方面會有更大的進(jìn)步。 圖 5— 11 導(dǎo) 柱 的結(jié)構(gòu) 黃 石 理 工 學(xué) 院 畢 業(yè) 設(shè) 計 論 文 25 致謝 本次設(shè)計是對我三年學(xué)習(xí)的考察。能夠順利的完成 , 在 這里很感謝我院全體老師為我們安排這次設(shè)計,無時無刻的默默的給予我們支持與指導(dǎo),感謝王蘭群老師,在設(shè)計過程中,我遇到了很多難題,就去請教她,感謝她給予這個機(jī)會讓我做這次跨學(xué)科的設(shè)計,也感謝她在工作很忙的情況下,還很耐心的指導(dǎo)我們?nèi)プ龃舜卧O(shè)計,并指引我閱讀相關(guān)的資料和書籍,幫助我補(bǔ)充和指正。同時也謝謝同組的同學(xué)對此次設(shè)計的全力以赴。從設(shè)計的過程中讓我知道,只要有恒心和耐心,再難的坎都能過去,更讓我明白,要想做好設(shè)計工作,是需要很大的耐性,忌驕忌躁。 黃 石 理 工 學(xué) 院 畢 業(yè) 設(shè) 計 論 文 26 參考文獻(xiàn) [ 1 ] 徐慶華 , 王曉青主編 《 機(jī)械制圖 》中國地質(zhì)大學(xué) 出版社 2021 [ 2 ] 朱燈林等 《 機(jī)械 CAD/CAM 技術(shù) 》 機(jī)械工業(yè)出版社, 2021 [ 3 ] 熊南峰 , 石其年 《 冷沖模具設(shè)計 》 科學(xué)出版社, 2021 [ 4 ] 吳崇峰 《 CAD/CAE/CAM 模具教程 》 中國輕工業(yè)出版社 , 2021 [ 5 ] 周濟(jì) 《 CAD 基礎(chǔ)及應(yīng)用 》 機(jī)械工業(yè)出版社, 1995 [ 6 ] 黃堯民 《 機(jī)械 CAD》 機(jī)械工業(yè)出版社, 1995 [ 7 ] 陳立德 《 機(jī)械設(shè)計基礎(chǔ) 》 高等教育出版社 , 2021 [ 8 ] 東北大學(xué)《機(jī)械零件設(shè)計手冊》編寫組,冶金工業(yè)出版社, 1994 [ 9 ] 丁紅宇主編《制圖標(biāo)準(zhǔn)手冊》中國標(biāo)準(zhǔn)出版社, 2021 [ 10 ] 李碩根,莫雨松《互換性與技術(shù)測量》中國計量出版社, 2021 [ 11 ] 王 少懷,《機(jī)械設(shè)計師手冊》電子工業(yè)出版社, 2021 [ 12 ] 何德譽(yù),《曲柄壓力機(jī)》北京機(jī)械工業(yè)出版社, 1997 [ 13 ] 朱立義,《冷沖模工藝與模具設(shè)計》重慶大學(xué)出版社, 2021 [ 14 ] 饒振綱,《行星齒輪傳動設(shè)計》化學(xué)工業(yè)出版社, 1994 [ 15 ] 劉舟通,余立剛,《模具制造工藝學(xué)》科學(xué)出版社, 2021 [ 16 ] 余小燕,鄭毅,《機(jī)械制造基礎(chǔ)》科學(xué)出版社, 2021 黃 石 理 工 學(xué) 院 畢 業(yè) 設(shè) 計 論 文 27 為你提供優(yōu)秀的畢業(yè)論文參考資料,請您刪除以下內(nèi)容, O(∩_∩)O謝謝!??! 2 Many people have the same mixed feelings when planning a trip during Golden Week.

However, it can also be the easiest way to ruin how you feel about a place and you may bee more fatigued after the holiday, due to battling the large crowds. During peak season, a dream about a place can turn to nightmare without careful planning, especially if you travel with children and older people.

Autumn in the northern part of the country es earlier 黃 石 理 工 學(xué) 院 畢 業(yè) 設(shè) 計 論 文 28 than the South. A September rain followed by the footprints of Autumn brings more colors to the once emerald green mountain and blooming grassland. Shutterbugs flock to see for themselves the marvel of splendid colors around the mountains and waters, many of whom have travel a long distance and even camp here only to capture a moment of the nature wonder.
