大連水產學院本科畢業(yè)論文(設計) 摘要
摘 要
我國是世界上機床產量最多的國家,但數(shù)控機床的產品競爭力在國際市場中仍處于較低水平,即使在國內市場也面臨著嚴峻的形勢:一方面國內市場對各類機床產品特別是數(shù)控機床有大量的需求,而另一方面卻有不少國產機床滯銷積壓,國外機床產品充斥市場,嚴重影響我國數(shù)控機床自主發(fā)展的勢頭。這種現(xiàn)象的出現(xiàn),除了有經營上、產品質量上和促銷手段上等的原因外,一個最主要的原因就是新產品(包括基型、變型和專用機床)的開發(fā)周期長,不能及時針對用戶的需求提供滿意的產品。
普通機床的數(shù)控化改造事業(yè)方興未艾,在我國目前形式下將大批故障機床尤其是一大批閑置的普通機床進行改造、升級,以較小的投入盡快使這批設備在經濟發(fā)展中發(fā)揮效能、創(chuàng)造效益,的確是許多企業(yè)的一項不可忽視的課題。

大連水產學院本科畢業(yè)論文(設計) C6140臥式車床的數(shù)控改造
文獻綜述
機床的數(shù)控改造,主要是對原有機床的結構進行創(chuàng)造性的設計,最終使機床達到比較理想的狀態(tài)。數(shù)控車床是機電一體化的典型代表,其機械結構同普通的機床有諸多相似之處。
數(shù)控化加工是機械加工行業(yè)朝高質量,高精度,高成品率,高效率發(fā)展的趨勢。結合我國實際國情,經濟型數(shù)控車床是我國從普通車床向數(shù)控車床發(fā)展的及其重要的臺階。利用現(xiàn)有的普通車床,對其進行數(shù)控化改造是一條低成本,高效益的途徑。
我國目前機床總量380余萬臺,而其中數(shù)控機床總數(shù)只有11.34萬臺,即我國機床數(shù)控化率不到3%。近10年來,我國數(shù)控機床年產量約為0.6~0.8萬臺,年產值約為18億元。機床的年產量數(shù)控化率為6%。我國機床役齡10年以上的占60%以上;10年以下的機床中,自動/半自動機床不到20%,F(xiàn)MC/FMS等自動化生產線更屈指可數(shù)(美國和日本自動和半自動機床占60%以上)。可見我們的大多數(shù)制造行業(yè)和企業(yè)的生產、加工裝備絕大數(shù)是傳統(tǒng)的機床,而且半數(shù)以上是役齡在10年以上的舊機床。用這種裝備加工出來的產品普遍存在質量差、品種少、檔次低、成本高、供貨期長,從而在國際、國內市場上缺乏競爭力,直接影響一個企業(yè)的產品、市場、效益,影響企業(yè)的生存和發(fā)展。所以必須大力提高機床的數(shù)控化率。
在美國、日本和德國等發(fā)達國家,它們的機床改造作為新的經濟增長行業(yè),生意盎然,正處在黃金時代。由于機床以及技術的不斷進步,機床改造是個"永恒"的課題。我國的機床改造業(yè),也從老的行業(yè)進入到以數(shù)控技術為主的新的行業(yè)。在美國、日本、德國,用數(shù)控技術改造機床和生產線具有廣闊的市場,已形成了機床和生產線數(shù)控改造的新的行業(yè)。在美國,機床改造業(yè)稱為機床再生(Remanufacturing)業(yè)。從事再生業(yè)的著名公司有:Bertsche工程公司、ayton機床公司、Devlieg-Bullavd(得寶)服務集團、US設備公司等。美國得寶公司已在中國開辦公司。在日本,機床改造業(yè)稱為機床改裝(Retrofitting)業(yè)。從事改裝業(yè)的著名公司有:大隈工程集團、崗三機械公司、千代田工機公司、野崎工程公司、濱田工程公司、山本工程公司等。
作為數(shù)控機床的重要功能部件,伺服系統(tǒng)的特性一直是影響系統(tǒng)加工性能的重要指標。圍繞伺服系統(tǒng)動態(tài)特性與靜態(tài)特性的提高,近年來發(fā)展了多種伺服驅動技術??梢灶A見隨著超高速切削、超精密加工、網(wǎng)絡制造等先進制造技術的發(fā)展,具有網(wǎng)絡接口的全數(shù)字伺服系統(tǒng)、直線電動機及高速電主軸等將成為數(shù)控機床行業(yè)的關注的熱點,并成為伺服系統(tǒng)的發(fā)展方向。本文針對普通車床C6140的結構,以及數(shù)控加工的基本理論進行研究后,采用了Inter公司的生產的單片機MCS-51T系統(tǒng)的8031作為數(shù)控系統(tǒng)的中央處理機進行對機床各部件的控制。
內容包括:系統(tǒng)運動方式的確定,伺服系統(tǒng)的選擇,執(zhí)行機構的結構及傳動方式的確定等內容。應根據(jù)設計任務和要求提出系統(tǒng)的總體方案,對方案進行分析,比較和論證,最后確定總體方案。

金屬切削
磨削、鉆削、鏜削和齒輪滾洗法
機床生產廠家一直在為顧客尋找更快、更高效的切削時期、更快的工作速度、更低的循環(huán)次數(shù)、以及增加金屬切削精度的方法。機床生產者花了許多他們的費用在高速加工設備上去提高他們的生產效益,比如在IMTS 2000上你將會看到最新的磨削、鉆削、樘削和齒輪滾洗方法。
更快、更可靠的心軸和和提高機床的控制是提高加工產量和生產力的主要因素?!案斓男妮S,提高生產力,是在一個堅果殼里”Chris Hetzer說,Hrafton,WI工程部代理總工程師,也就是說未來將出現(xiàn)新的心軸并且在IMTS上會有多軸。
Hetzer說:“你不得不正確的去做心軸的設計,并且心軸不僅要在高速下操作,而且它也要具備能夠隨著生產的要求增加速度的特性,這也意味著動態(tài)的心軸要能確保能在不同的速度、不同的載荷,不同的刀具下能正常工作;這樣,心軸不得不具備一定的硬度,同時他也要具備一定的韌性以便他能夠經得起摩擦、不同程度的撞擊,包括刀具”
一個可調心軸所能套的齒輪內孔直徑范圍比較大,即一個“可調心軸”能適用于多個內孔直徑不同的齒輪,代替多根普通心軸,能減少心軸的磨損,所需心軸長度相對比較短,省材。心軸屬于斜楔夾緊裝置,用于機械加工中的產品檢測作輔助裝置,主要作為齒輪測量時的支承件。一套“可調徑心軸”可代替多跟規(guī)格不同的現(xiàn)有“普通心軸”的作用,所以“可調徑心軸”比現(xiàn)有的“普通心軸”更有使用價值和市場價值。
Hetzer記錄,Gilman?的心軸設計需要用FEA確保單元與單元之間的粘合力,其實這是生產一個快速運轉心軸過程中的一小部分,我們真正想要尋找這些高速的心軸就是在整個生產過程中它的穩(wěn)定性,比如說,一個170mm的心軸在30KW的情況下,它的轉速是24000rpm,我們的顧客想要他們的第一個心軸是這樣,第二個是這樣,第三個是這樣,第四個也是這樣……
Hetzer說,真正要確保每個單元之間的粘合力是非常困難的,它需要廣大的FEA分析,這就包括了許多東西,例如生產公差、軸承質量,但是剩下的是你的設計和分析。
“用戶在生產環(huán)境中用這種高速旋轉的心軸去操縱一個機器,他們想要持續(xù)的工作,但是如果心軸達不到這種要求”,Hetzer說,“人們將會把它報廢掉—這是典型的在高速旋轉機器上可能發(fā)生的事情,這時這個心軸將要被換掉,但是如果被換上來的那個心軸和原來的那個心軸沒有同樣的切削特性,顧客們將不得不花許多的時間、許多的金錢去讓這臺機器像原來一樣運轉?!?
在IMTS中, Gilman將介紹他的15000轉/分鐘,高速的帶驅動的心軸,這種裝置主要呈現(xiàn)一根尼龍帶和一個交叉的齒狀構造。Gilman也將介紹一個新的揉性的生產空間,這個系統(tǒng)是重新建造的3軸空間,X-Y-Z模塊出現(xiàn)在400×400×400工作空間內。多軸模塊能夠使用帶驅動的心軸,然而這種心軸使用了Gilman ’Swedish 的母公司SKF生產的陶瓷圓柱滾筒軸承,Hetzer說它的主要特點是心軸能夠忍受由高速旋轉產生能量而帶動心軸的自由運動。
Hurco新的VMCS提供了標準的10000轉/分鐘的心軸,但是它也可以通過軸系轉變?yōu)?0000轉/分鐘,這樣就形成了很高的在X和Y軸方向的橫向速度30米/分鐘,當被配置Hurco提高的UltiPro Ш在持續(xù)5.1—6.4米/分鐘的進給過程中精度和表面粗糙度不受影響的高速運動控制軟件,那么這個單元將會勝過3—D周線工作法。
在磨削設備中,許多的擁護對加快磨削速度有一種特別的期待,現(xiàn)在最新的碳化物工具正在幫助解決這個問題,“更快的速度,更快的吞吐量,更快的循環(huán)次數(shù)是每一個人都期待的”磨削執(zhí)行副總裁Jon Wolf和機器工具制造商Sugino Corp,說“提高磨削速讀的關鍵是提高磨床的進給量,例如,在3軸的磨床加工中,它第一提供最小的循環(huán)次數(shù)(36—51米/分鐘),但是你這必須有相應的進給量,它可以是8米/分鐘,可以是20—23米/分鐘。
“技術在不斷的變化中,碳化物公司正在制造更好的工具,能夠忍受更高的進給量和更快速度的碳化物”Wolf追加道“刀具的尺寸也是邊得越來越多樣化,有很多的技術在刀具尺寸上,,它可以讓你工作更快,散熱更快”。增加刀具的壽命是每一個碳化物公司都尋找的,它會使機器具有更高,更快的進給量和加工速度。我們機器工具公司總是在刀具曲線研究技術的后面,因為我們總是想要跟上機加工,機加工人們引導著這個工業(yè)。
速度和精度是金屬加工過程中兩個關鍵的因素,但是在孔的加工過程中,快速的心軸旋轉速度并不意味著高效的切削速度,Zagar 副總裁Randy Toberts提出了證明,用他的多軸鉆頭或齒輪箱,Zagar Inc主張同時對一組孔進行高速加工,而不是一次只加工一個孔。
“我們現(xiàn)在會看到Cpk率和1.33—2.0的Ppk率,這些參數(shù)對于產品的使用者來說是非常重要的,比如一個OEM或者一個自動控制室”Roberts說,“例如對于一兩車來說GM 可能需要一個輪子控制中心,然而輪子控制中心有5~6個要鉆的孔并且是沉頭孔,他們中的每一個都必須保持1.67Cpk,每一個孔的公差要求都非常高,位置要求也是很高?!?
“不管是摸削還是鉆削,高速旋轉對不同的人來講都意味著不同的事情?!盧oberts說,“在一般情況下,高速就會對旋轉速度有影響,例如在傳統(tǒng)的加工一個孔的情況下”如果你在一個加工中心或者是一個單個心軸的機器想進行多孔的加工,顯然一個單個的心軸一次只能加工一個孔。對于你加工得有多快是沒有關系的,如過你加工一個孔需要5秒鐘,加工兩個孔將花你10秒的時間,但是還要加上機器從第一個孔移到第二個孔的時間。
在齒輪的加工設備IMTS中, 在國家的討論和機械中心,將展示最新版本的垂直滾動架形成的機器.Wagner說, “不是傳統(tǒng)的能夠滾動零件在傳統(tǒng)的水壓和速度下,我們現(xiàn)在能夠利用最新的CNC技術去驅動滑塊,并且它能讓顧客變化速度就象他們變換他們的零件一樣,最關鍵的事情是零件和刀具壽命增加了”
國家討論的PFM/NC是在已經被賣了30年的垂直機器上指甲滾動成型機和CNC控制,因為給機器在一個垂直的平面上滾動,它形成了一個重要的軌跡,Wagner說,它是朝著全球的制造業(yè)發(fā)展并且優(yōu)化了工廠的空間.
PFM滾動機器用了少于機器百分之66的空量和能量,并且它的質量非常好”
下面的產品是你在IMTS中進行金屬加工和齒輪成型的產品

Metal Cutting
Grinding, drilling, boring and gear roller washing method
Machine tool manufacturers have been looking for customers faster, more efficient cutting period, the faster speed, lower cycle times and increase the accuracy of metal-cutting approach. Machine tool producers to spend a lot of their costs go up in the high-speed processing equipment to improve their production efficiency, such as in the IMTS 2000, you will see the latest grinding, drilling, cutting and gear roller washing method.
Faster, more reliable and improve the spindle and machine tool control is to improve the processing yield and productivity of the main factors. "Spindle faster, increasing productivity in a nut shell in" Chris Hetzer said, Hrafton, WI Division Deputy Chief Engineer, that is to say the future will be the emergence of new spindle and there will be a multi-axis IMTS.
Hetzer said: "You do have to correct the design of spindle and spindle not only in high-speed operation, and it also has to increase with the rate of production characteristics, this also means that the dynamics of spindle to be able to ensure that the different speeds, different loads and different tool to work under; This spindle had to have a certain degree of hardness, at the same time, he must also possess a certain degree of toughness so that he can stand up to friction, to varying degrees impact, including the tool "
An adjustable spindle of the gear can be set within the scope of relatively large diameter, that is, a "adjustable spindle" can be applied in a variety of different hole diameter gear, instead of an ordinary multi-spindle, spindle to reduce wear and tear required spindle length is relatively short, the provincial timber. Wedge spindle clamping devices are used for machining of products as an aid to detection devices, used primarily as a measure of support gear pieces. A set of "adjustable diameter spindle" can be replaced by a different and more with the specifications of the existing "common spindle" role, it is "adjustable mandrel diameter" than the existing "common spindle" use value and market value of more .
Hetzer Records, Gilman spindle design of the need to use FEA to ensure that the units and the bonding between units, and in fact this is a fast-running production in the process of spindle a small part, we really want to find these high-speed spindle is in the the production process of its stability, for example, a 170mm spindle in the case of 30KW, its speed is 24000rpm, our customers want their first spindle that is the case, the second is the case, the third is this the fourth the same way ... ...
Hetzer said the real intention is to ensure that the bonding between each unit is very difficult to force, it requires that the analysis of the FEA, which includes many things, such as manufacturing tolerances, bearing quality, but the rest of your design and analysis .
"Users in a production environment with such high-speed rotating spindle to control a machine, they want to continue to work, but if spindle not such a request", Hetzer said, "people will be scrapping it out -- This is typical in high-speed rotary machine may be what is happening, when the spindle to be replaced, but if that were put to the original spindle and spindle that do not have the same cutting characteristics, customers will have to spent a lot of time, a lot of money to let the machine running the same as the original. "
In the IMTS in, Gilman will present his 15,000 rev / minute with high-speed spindle drive, the device has a major nylon belt and a cross-cutting structure of the dentate. Gilman also will introduce a new production space of kneading, the system is re-constructed 3-axis space, XYZ module appears in the 400 × 400 × 400 work spaces. Modules to use with multi-axis drive-axis of the heart, but the use of spindle Gilman 'Swedish production of the parent company of SKF cylindrical roller bearings ceramic, Hetzer said the main characteristics of the spindle can not tolerate the energy generated by the high-speed rotation and drive spindle of the Freedom Movement.
Hurco provided VMCS new standards 10000 rev / min spindle of, but it can also be changed through the shaft of 30,000 rev / min, so that the formation of a high X and Y axis in the direction of the horizontal speed of 30 m / min , when the Hurco is configured to increase the UltiPro Ш sustained 5.1-6.4 m / minute to process into the accuracy and surface roughness is not affected high-speed motion control software, this unit will be better than the 3-D line work week law .
In the grinding equipment, a lot of support to speed up the grinding speed on a special look, and now the latest carbide tools are helping to solve this problem, "faster, faster throughput, faster cycle times is everyone looks forward to the "grinding Jon Wolf, executive vice president of tools and machinery manufacturers Sugino Corp, said," to improve grinding speed-reading the key is to improve the feed grinder, for example, in the 3-axis grinding machine, it the first cycles to provide the smallest (36-51 m / min), but you must have a corresponding feed rate, it can be 8 m / min, it can be 20-23 m / min.
"Technology changes constantly, the carbide is the creation of a better tool that can tolerate a higher feed rate and faster speed carbide" Wolf added Road "is the size of the tool edge are becoming more and more diversified, There are a lot of technology in the tool size, it can let you work faster, faster heat dissipation. " Increase in tool life of carbide for each company are looking for, it will make the machine a higher, faster feed rate and processing speed. Machine tool company, we always research techniques in the tool behind the curve, because we always want to keep up with the machine processing, machining and guide people to this industry.
Speed and accuracy of processing metal two key factors, but in the process of hole machining, rapid rate of spindle rotation speed does not mean that the efficient, Zagar, vice president Randy Toberts has proved that with his multi - drill shaft or gearbox, Zagar Inc advocate hole at the same time a group of high-speed processing, and not only the processing time of a hole.
"Now we see that the rate of Cpk and Ppk rate of 1.33-2.0, the product of these parameters is very important to users, such as an OEM or an automatic control room" Roberts said, "For example, 12 cars GM may need a wheel control center, control center, however the wheels are 5 to 6 months to drill the hole and head holes, each of them must be maintained 1.67Cpk, each hole has a very high tolerance requirements, location requirements is very high. "
"Whether it is cutting or drilling touch, high-speed rotation of the different people in terms of both mean different things." Roberts said, "Under normal circumstances, the speed will affect the speed of rotation, for example, in the traditional processing of a hole the case of "If you, or in a machining center is a single spindle machine would like to carry out the processing of porous, apparently of a single spindle can only be processed once a hole. For how fast you process is not related to processing such as a hole you need to 5 seconds, and processing the two holes will cost you 10 seconds of the time, but would also like to add the machine from the first hole to the second hole time.
Processing equipment in the gear IMTS, in the national discussion and mechanical centers, will showcase the latest version of the vertical plane formed by the rolling machine. Wagner said, "is not a traditional scroll parts to the traditional pressure and speed, we are now able to using the latest CNC technology to drive the slider, and it can change the speed of customers as they transform their parts, the most important thing is to spare parts and tool life has increased, "
Countries to discuss the PFM / NC that has been sold in 30-year vertical rolling machine nail machine and CNC control, because the machine in a plane perpendicular to the rolling, it formed an important track, Wagner said, it is toward the development of the manufacturing industry and the global optimization of the factory space.
PFM machine rolling machine to use 66 percent less than the amount of space and energy, and the quality of it very good "
The following products are you IMTS in metalworking and gear molding products
