【導讀】花鍵軸在機械傳動中應用非常廣泛,按行業(yè)分有:汽車、各類生產(chǎn)。用機械、航空航天、船舶重工等領域都有用到,花鍵是用來傳遞動力。的，但外面要套一個東西,并且要求花鍵軸與外層是。上下運動時就是花鍵軸在滑動.本畢業(yè)設計課題來源江蘇洪澤花鍵軸制造有限公司，是花鍵軸。本設計針對江蘇洪澤花鍵軸制造有限公司的花軸進行設計。根據(jù)該零件的圖紙及技術要求，對該零件進行了詳細的數(shù)控加工工。藝分析，根據(jù)分析的結果，確定了該零件的加工方法、裝夾方式、定位基準、使用刀具、加工順序安排、工步劃分，走刀路線和切削。用量，設備選用等，并編制了該零件的數(shù)控加工工藝卡片、刀具卡。片和數(shù)控加工工序卡片等，最后，采用手工編程編制了該零件的數(shù)。本課題研究的國內(nèi)外現(xiàn)狀。1674年丹麥天文學家羅默首次提出用外擺線作齒廓曲線，以得到運。按照原理和工作程序進行生產(chǎn)和加工，保證能夠在生產(chǎn)中發(fā)揮重要的作

　　

【正文】 外徑千分尺， 表面粗糙度儀 螺紋 0 + + 三坐標測量儀、表面粗糙度儀 右端鍵槽 + 0 + + + 三坐標測量儀、表面粗糙度儀 花鍵槽 + + + 三坐標測量儀、表面粗糙度儀 誤差產(chǎn)生的原因分析 1． 端面及外圓尺寸及粗糙度誤差是 由于刀具支架的剛度不強和刀具伸出較長，在加工時容易產(chǎn)生振動從而影響其表面質(zhì)量，也容易磨損造成加工后的輪廓精度不太高。 2． 鍵槽的加工誤差 是由于刀在對刀時容易產(chǎn)生對刀精度不高，在刀的裝夾和刀補的選擇時，由于在加工過程中由于沒有先進的測量儀器在不卸下工件的時候無法進行測量，只能加工后進行測量，加上機床在加工過程中有震動，和爬行現(xiàn)象使加工精度偏差很大，與環(huán)境影響存在一定的誤差，另外還有夾具的定位精度有一定影響。 ******學院畢業(yè)論文 38 第六章 結論 由于 該零件為典型的花鍵軸類零件，在加工過程中應用的數(shù)控專業(yè)的多方面知識，在對該復雜零件的數(shù)控加工工藝制訂過程中很多部分需要注意，主要是對軸類零件進行數(shù)控加工編程，以及鍵槽輪廓數(shù)控加工編程。 ，切削速度，刀具選擇要合理，在加工時在用百分表找正時要軸向面與端面都要進行找正以免產(chǎn)生變形影響精度。 ，不能進行兩次裝夾以免亂牙，根據(jù)機床，刀具選擇合適的轉(zhuǎn)速。 。在裝夾偏心墊片時夾緊力要適中，以免變形影響精度。 用小徑定心精度高 ,穩(wěn)定性好 ,能用磨削花鍵的方法消除熱處理后存在的變形 ,并有助于提高花鍵副的接觸面 ,從而提高產(chǎn)品的使用壽命。但磨削花鍵軸小徑時 ,形位公差難以保證 ,導致誤差影響定心精度及裝配精度 ,影響鍵側間隙及傳動精度。 威海職業(yè)學院畢業(yè)論文 39 參考文獻 ，楊善迎主編《數(shù)控加工工藝與編程》，天津大學出版社 ，主編，《機械設計課程設計》，高等教育出版社， ，主編，《工程材料與材料成形工藝》，天津大學出版社， ，主編，《數(shù)控車削編程與考級》， 北京：化學工業(yè)出版社 ， ，主編，《 AutoCAD2021 實用教程》 , 天津大學出版社 ，主編，《機械制圖》，天津大學出版社， ，主編，《機械加工工藝制訂》，天津大學出版社， ，鄭軍，《數(shù)控技術及應用》，天津大學出版社， ，《主編現(xiàn)代數(shù)控加工工藝與裝備》，北京：清華大學出版社， ，主編，《機械設計基礎》 北京 : 高等教育出版社 ，《數(shù)控車削加工實訓及案例解析》，北京：化學工業(yè)出版社， ，主編，《金屬材料與熱處理》，北京：中國勞動社會保障出版社，2021 ，《機械制造工藝裝備設計適用手冊 [M]》，銀州：寧夏人民出版，1991。 14．劉登平，《機械制造工藝及機床夾具設計》，北京理工大學出版社 ******學院畢業(yè)論文 40 致謝 本次畢業(yè)設計已經(jīng)接近尾聲，作為一個?？粕漠厴I(yè)設計，由于經(jīng)驗的匱乏，難免有許多考慮不周全的地方， 威海職業(yè)學院指導老師戚曉霞對本次的畢業(yè)設計的任務、要求以及說明論 文的格式、章節(jié)的設置都提出了許多寶貴的修改和補充意見，在此謹致謝意。并對本次畢業(yè)設計中的各位同學的幫助表示謝意以及本次設計中的所列參考文獻的作者們表示謝意。謝謝您們在本次設計對我的指導，讓我受益匪淺，如果僅靠個人的努力很難完成。 最后，感謝評閱本論文的老師，謝謝他們在百忙之中抽出時間來翻閱此論文，祝老師工作愉快，身體健康。 g an employment tribunal claim Employment tribunals sort out disagreements between employers and employees. You may need to make a claim to an employment tribunal if: ? you don39。t agree with the disciplinary action your employer has taken against you ? your employer dismisses you and you think that you have been dismissed unfairly. For more information about dismissal and unfair dismissal, see Dismissal. You can make a claim to an employment tribunal, even if you haven39。t appealed against the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept it. If you are worried about how the time limits apply to you, take advice from one of the anisations listed under Further help. Employment tribunals are less formal than some other courts, but it is still a legal process and you will need to give evidence under an oath or affirmation. 威海職業(yè)學院畢業(yè)論文 41 Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the anisations listed under Further help. If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。t charge you more than 35% of your pensation if you win the case. If you are thinking about signing up for a damagesbased agreement, you should make sure you39。re clear about the terms of the agreement. It might be best to get advice from an experienced adviser, for example, at a Citizens Advice Bureau. To find your nearest CAB, including those that give advice by , click on nearest CAB.
