珩磨機(jī)珩磨頭的結(jié)構(gòu)設(shè)計(jì) 1 摘 要 珩磨加工是一種具有廣泛前途的切削技術(shù) 它不僅是一種能提高表 面粗糙度的加工方法 而且成為能夠快速可靠地去除一定的余量 提高 表面粗糙度和精度的一種半精加工和精加工的工藝方法 珩磨不需要特 殊的條件就能使零件獲得精確的尺寸 幾何精度 良好的表面質(zhì)量和高 的使用壽命 因而很快地推廣應(yīng)用于船舶 軸承 軍工和工程機(jī)械等制 造業(yè)中 由于近幾年對大型零件的需求不斷增加 進(jìn)而對珩磨頭的結(jié)構(gòu) 設(shè)計(jì)提出了新的需求 本畢業(yè)設(shè)計(jì)正是從實(shí)際使用出發(fā) 進(jìn)行珩磨機(jī)珩 磨頭的設(shè)計(jì) 本設(shè)計(jì)是對珩磨頭的結(jié)構(gòu)設(shè)計(jì) 首先通過實(shí)習(xí)認(rèn)識了解珩磨機(jī)的工 作原理 清楚其結(jié)構(gòu)組成 然后重點(diǎn)觀察現(xiàn)有珩磨頭的結(jié)構(gòu) 對特定型 號的珩磨機(jī)掌握其運(yùn)動參數(shù)的選擇原則 油石個數(shù)的選擇及分布原理 漲錐的設(shè)計(jì)技術(shù)要求以及進(jìn)給機(jī)構(gòu)的運(yùn)動裝置等 最后了解現(xiàn)有珩磨頭 結(jié)構(gòu)的缺點(diǎn) 確定對大孔加工所用珩磨頭的總體方案 其次利用設(shè)珩磨頭結(jié)構(gòu)的設(shè)計(jì)原理對各個具體零件進(jìn)行詳細(xì)的設(shè)計(jì) 然后對個別零件進(jìn)行校核 使設(shè)計(jì)出的結(jié)構(gòu)可確保磨削可靠運(yùn)行 在此 基礎(chǔ)上完成了本畢業(yè)論文的寫作 最后繪制整套的裝珩磨頭結(jié)構(gòu)的裝配 圖和零件圖 通過對本課題珩磨頭的結(jié)構(gòu)設(shè)計(jì) 使書本知識和理論與實(shí)際生產(chǎn)相 結(jié)合 加強(qiáng)了對機(jī)械零件 機(jī)械制造工藝學(xué)以及現(xiàn)代磨削技術(shù)等相關(guān)專 業(yè)知識的理解 使自己能運(yùn)用書本知識設(shè)計(jì)出基本符合生產(chǎn)要求的零部 件 在論文中我充分地運(yùn)用了大學(xué)期間所學(xué)到的知識 進(jìn)行了研究 鞏 固和深化 達(dá)到了預(yù)期的設(shè)計(jì)意圖 關(guān)鍵詞 珩磨頭 漲錐 進(jìn)給機(jī)構(gòu) 油石 珩磨機(jī)珩磨頭的結(jié)構(gòu)設(shè)計(jì) 2 THE STRUCTURE DESIGN OF THE HEAD OF A MACHINE HONING ABSTRACT Honing processing is a kind of extensive promising cutting technology It is not only a kind of surface roughness can improve the processing method and be able to quickly remove certain allowance reliable improving the surface roughness and the precision of a half finishing and finishing process method Honing don t need special conditions can make parts get precise dimensions geometric accuracy and good surface quality and high service life so quickly applied on ships bearing military and engineering machinery and other manufacturing industries Because of the large parts in recent years and the increasing demand for honing the structure design head puts forward new requirements The graduation design is starting from the actual use honing head design machine honing This design is the structure design of head honing first through internships understanding the working principle of honing clear machine and its structure is composed Then the key observe the structure of the existing honing and master the models of the motion parameters selection for head of honing machines principle in particular the selection and oil stone number distribution principle the design technology requirements up cone and the movement to institutions into devices Finally understand the shortcomings of existing honing determine the head of structure of large hole processing the overall scheme of honing head used Secondly using the design principle of the head detailed design each structure of specific parts Then checking the individual parts of designed structure can ensure grinding reliable operation Based on this completed this graduation thesis writing Finally draw full sets of outfit honing the head structure of spare parts and assembly drawing Through this project structure design of honing head make text book knowledge and theory combining with practical production Strengthening the understanding of the mechanical parts mechanical manufacturing technology and modern grinding technology and related professional knowledge understanding Make me to use the book knowledge designed with production requirements of the basic components Make me to use the book knowledge to design the basic components with production 珩磨機(jī)珩磨頭的結(jié)構(gòu)設(shè)計(jì) 3 requirements In the paper I fully using university period the knowledge I have learned then Studied strengthening and deepening to achieve the expected design intent KEY WORDS Honing head feeding institutions Rise cone oil ston 珩磨機(jī)珩磨頭的結(jié)構(gòu)設(shè)計(jì) 4 目 錄 第一章 前言 1 1 1 課題研究的目的及意義 1 1 2 國內(nèi)外研究狀況 1 1 3 課題研究基本設(shè)計(jì)思路和研究手段 2 1 4 論文結(jié)論和成果形式 4 第二章 精整加工技術(shù) 5 2 1 精整加工的范疇及特點(diǎn) 5 2 2 精整加工機(jī)理 6 第三章 普通珩磨 7 3 1 珩磨加工原理 7 3 2 珩磨加工的特點(diǎn) 10 3 3 珩磨的切削過程 11 3 4 珩磨頭的結(jié)構(gòu)形式 12 第四章 珩磨頭的結(jié)構(gòu)設(shè)計(jì) 17 4 1 珩磨油石的選擇 17 4 2 珩磨頭基體結(jié)構(gòu)設(shè)計(jì) 24 4 3 漲錐的設(shè)計(jì) 28 4 4 導(dǎo)向裝置的設(shè)計(jì) 30 4 5 手動進(jìn)給機(jī)構(gòu)的設(shè)計(jì) 30 第五章 珩磨用量的選擇 33 5 1 切削速度 V 與網(wǎng)文夾角 33 5 2 油石工作壓力的選擇 36 5 3 擴(kuò)漲進(jìn)給速度的選擇 37 5 4 工作行程的調(diào)整與計(jì)算 38 珩磨機(jī)珩磨頭的結(jié)構(gòu)設(shè)計(jì) 5 5 5 加工余量的選擇 39 5 6 珩磨前工序要求 40 5 7 珩磨液的選擇 40 第六章 珩磨頭結(jié)構(gòu)薄弱零件的校核 42 6 1 零件 3 圓柱銷扭轉(zhuǎn)強(qiáng)度的校核 42 6 2 零件 11 六角頭沉頭螺釘?shù)膹?qiáng)度校核 43 結(jié)束語 46 致謝 47 參考文獻(xiàn) 48
