Machine design theory
The machine design is through designs the new product or improves the old product to meet the human need the application technical science. It involves the project technology each domain, mainly studies the product the size, the shape and the detailed structure basic idea, but also must study the product the personnel which in aspect the and so on manufacture, sale and use question.
If front sues, the machine design goal is the production can meet the human need the product. The invention, the discovery and technical knowledge itself certainly not necessarily can bring the advantage to the humanity, only has when they are applied can produce on the product the benefit. Thus, should realize to carries on before the design in a specific product, must first determine whether the people do need this kind of product
Must regard as the machine design is the machine design personnel carries on using creative ability the product design, the system analysis and a formulation product manufacture technology good opportunity. Grasps the project elementary knowledge to have to memorize some data and the formula is more important than. The merely service data and the formula is insufficient to the completely decision which makes in a good design needs.
A good design personnel should dare to propose the new idea, moreover is willing to undertake the certain risk, when the new method is not suitable, use original method. Therefore, designs the personnel to have to have to have the patience, because spends the time and the endeavor certainly cannot guarantee brings successfully. A brand-new design, the request screen abandons obsoletely many, knows very well the method for the people. Because many person of conservativeness, does this certainly is not an easy matter. A mechanical designer should unceasingly explore the improvement existing product the method, should earnestly choose originally, the process confirmation principle of design in this process, with has not unified it after the confirmation new idea.
Newly designs itself can have the question occurrence which many flaws and has not been able to expect, only has after these flaws and the question are solved, can manifest new goods come into the market the product superiority. Therefore, a performance superior product is born at the same time, also is following a higher risk. Should emphasize, if designs itself does not request to use the brand-new method, is not unnecessary merely for the goal which transform to use the new method.
In the design preliminary stage, should allow to design the personnel fully to display the creativity, not each kind of restraint. Even if has had many impractical ideas, also can in the design early time, namely in front of the plan blueprint is corrected. Only then, only then does not send to stops up the innovation the mentality. Usually, must propose several sets of design proposals, then perform the comparison. Has the possibility very much in the plan which finally designated, has used certain not in plan some ideas which accepts.
An important question, project engineer must be able to carry on the exchange and the consultation with other concerned personnel. In the initial stage, designs the personnel to have to carry on the exchange and the consultation on the preliminary design with the administrative personnel, and is approved. This generally is through the oral discussion, the schematic diagram and the writing material carries on.
Usually, can have some problem in the manufacture process. Possibly can request to some components size or the common difference makes some changes, causes the components the production to change easily. But, in the project change must have to pass through designs the personnel to authorize, guaranteed cannot damage the product the function. Sometimes, when in front of product assembly or in the packing foreign shipment experiment only then discovers in the design some kind of flaw. These instances exactly showed the design is a dynamic process. Always has a better method to complete the design work, designs the personnel to be supposed unceasingly diligently, seeks these better method.
Recent year, the engineerig material choice already appeared importantly. In addition, the choice process should be to the material continuously the unceasing again appraisal process. The new material unceasingly appears, but some original materials can obtain the quantity possibly can reduce. Because the material does not select when created the product responsibility lawsuit, has already had the profound influence. In addition, the material and between the material processing interdependence is already known by the people clearly. Therefore, in order to can and guarantees the quality in the reasonable cost under the premise to obtain satisfaction the result, project engineer makes engineers all to have earnestly carefully to choose, the determination and the use material.
Makes any product the first step of work all is designs. Designs usually may divide into several explicit stages: (a) preliminary design; (b) functional design; (c) production design. In the preliminary design stage, the designer emphatically considered the product should have function. Usually must conceive and consider several plans, then decided this kind of thought is whether feasible; If is feasible, then should makes the further improvement to or several plans.
In the production design stage, is should completely determine with the material related main question the material, causes them to adapt with the existing equipment, can use the existing equipment economically to carry on the processing, moreover the material quantity can quite be easy to guarantee the supply.
In the manufacture process, inevitably can appear to uses the material to make some changes the situation. The experience indicated that, may use certain cheap materials to take the substitute. However, in the majority situation, in will carry on the production later to change the material to have in to start before the production to change the price which the material will spend to have to be higher than. Completes the choice of material work in the design stage, may avoid the most such situations. Started after the production manufacture to appear has been possible to supply the use the new material is replaces the material the most common reason. Certainly, these new materials possibly reduce the cost, the improvement product performance. But, must carry on the earnest appraisal to the new material, guarantees its all performance all to answer the purpose. Must remember that, the new material performance and the reliable very few pictures materials on hand such understood for the people. The majority of products expiration and the product accident caused by negligence case is because in selects the new material to take in front of substitution material, not truly understood their long-term operational performance causes.
The product responsibility lawsuit forces designs the personnel and the company when the choice material, uses the best procedure. In the material process, five most common questions are: (a) did not understand or cannot use about the material application aspect most newly the best information paper; (b) has not been able to foresee and to consider the dusk year possible reasonable use (for example to have the possibility, designs the personnel also to be supposed further to forecast and the consideration because product application method not when creates consequence.
Through to the above some questions analysis, may obtain these questions is does not have the sufficient reason existence the conclusion. May for avoid these questions to these questions research analyses the appearance indicating the direction. Although uses the best choice of material method not to be able to avoid having the product responsibility lawsuit, designs the personnel and the industry carries on the choice of material according to the suitable procedure, may greatly reduce the lawsuit the quantity.
May see from the above discussion, the choice material people should to the material nature, the characteristic and the processing method have comprehensive and the basic understanding.
機(jī)械設(shè)計(jì)理論
機(jī)械設(shè)計(jì)是一門通過設(shè)計(jì)新產(chǎn)品或者改進(jìn)老產(chǎn)品來滿足人類需求的應(yīng)用技術(shù)科學(xué)。它涉及工程技術(shù)的各個(gè)領(lǐng)域,主要研究產(chǎn)品的尺寸、形狀和詳細(xì)結(jié)構(gòu)的基本構(gòu)思,還要研究產(chǎn)品在制造、銷售和使用等方面的問題。
如前所訴,機(jī)械設(shè)計(jì)的目的是生產(chǎn)能夠滿足人類需求的產(chǎn)品。發(fā)明、發(fā)現(xiàn)和科技知識(shí)本身并不一定能給人類帶來好處,只有當(dāng)它們被應(yīng)用在產(chǎn)品上才能產(chǎn)生效益。因而,應(yīng)該認(rèn)識(shí)到在一個(gè)特定的產(chǎn)品進(jìn)行設(shè)計(jì)之前,必須先確定人們是否需要這種產(chǎn)品。
應(yīng)當(dāng)把機(jī)械設(shè)計(jì)看成是機(jī)械設(shè)計(jì)人員運(yùn)用創(chuàng)造性的才能進(jìn)行產(chǎn)品設(shè)計(jì)、系統(tǒng)分析和制定產(chǎn)品的制造工藝學(xué)的一個(gè)良機(jī)。掌握工程基礎(chǔ)知識(shí)要比熟記一些數(shù)據(jù)和公式更為重要。僅僅使用數(shù)據(jù)和公式是不足以在一個(gè)好的設(shè)計(jì)中做出所需的全部決定的。
一個(gè)好的設(shè)計(jì)人員應(yīng)該勇于提出新的想法,而且愿意承擔(dān)一定的風(fēng)險(xiǎn),當(dāng)新的方法不適用時(shí),就使用原來的方法。因此,設(shè)計(jì)人員必須要有耐心,因?yàn)?所花費(fèi)的時(shí)間和努力并不能保證帶來成功。一個(gè)全新的設(shè)計(jì),要求屏棄許多陳舊的,為人們所熟知的方法。由于許多人墨守成規(guī),這樣做并不是一件容易的事。一位機(jī)械設(shè)計(jì)師應(yīng)該不斷地探索改進(jìn)現(xiàn)有的產(chǎn)品的方法,在此過程中應(yīng)該認(rèn)真選擇原有的、經(jīng)過驗(yàn)證的設(shè)計(jì)原理,將其與未經(jīng)過驗(yàn)證的新觀念結(jié)合起來。
新設(shè)計(jì)本身會(huì)有許多缺陷和未能預(yù)料的問題發(fā)生,只有當(dāng)這些缺陷和問題被解決之后,才能體現(xiàn)出新產(chǎn)品的優(yōu)越性。因此,一個(gè)性能優(yōu)越的產(chǎn)品誕生的同時(shí),也伴隨著較高的風(fēng)險(xiǎn)。應(yīng)該強(qiáng)調(diào)的是,如果設(shè)計(jì)本身不要求采用全新的方法,就沒有必要僅僅為了變革的目的而采用新方法。
在設(shè)計(jì)的初始階段,應(yīng)該允許設(shè)計(jì)人員充分發(fā)揮創(chuàng)造性,不受各種約束。即使產(chǎn)生了許多不切實(shí)際的想法,也會(huì)在設(shè)計(jì)的早期,即繪制圖紙之前被改正掉。只有這樣,才不致于堵塞創(chuàng)新的思路。通常,要提出幾套設(shè)計(jì)方案,然后加以比較。很有可能在最后選定的方案中,采用了某些未被接受的方案中的一些想法。 通常 ,在制造過程中會(huì)出現(xiàn)某個(gè)問題??赡軙?huì)要求對(duì)某個(gè)零件尺寸或公差作一些更改,使零件的生產(chǎn)變得容易。但是,工程上的更改必須要經(jīng)過設(shè)計(jì)人員批準(zhǔn),以保證不會(huì)損傷產(chǎn)品的功能。有時(shí),在產(chǎn)品的裝配時(shí)或者裝箱外運(yùn)前的試驗(yàn)中才發(fā)現(xiàn)設(shè)計(jì)中的某種缺陷。這些事例恰好說明了設(shè)計(jì)是一個(gè)動(dòng)態(tài)過程??偸谴嬖谥玫姆椒▉硗瓿稍O(shè)計(jì)工作,設(shè)計(jì)人員應(yīng)該不斷努力,尋找這些更好的方法。
這些年來,工程材料的選擇已經(jīng)顯得重要。此外,選擇過程應(yīng)該是一個(gè)對(duì)材料的連續(xù)不斷的重新評(píng)價(jià)過程。新材料不斷出現(xiàn),而一些原有的材料的能夠獲得的數(shù)量可能會(huì)減少。。由于材料選用不當(dāng)造成的產(chǎn)品責(zé)任訴訟,已經(jīng)產(chǎn)生了深刻的影響。此外,材料與材料加工之間的相互依賴關(guān)系已經(jīng)被人們認(rèn)識(shí)得更清楚。因此,為了能在合理的成本和確保質(zhì)量的前提下獲得滿意的結(jié)果,設(shè)計(jì)工程師的制造工程師都必須認(rèn)真仔細(xì)地選擇、確定和使用材料。
制造任何產(chǎn)品的第一步工作都是設(shè)計(jì)。設(shè)計(jì)通常可以分為幾個(gè)明確的階段:(a)初步設(shè)計(jì);(b)功能設(shè)計(jì);(c)生產(chǎn)設(shè)計(jì)。在初步設(shè)計(jì)階段,設(shè)計(jì)者著重考慮產(chǎn)品應(yīng)該具有的功能。通常要設(shè)想和考慮幾個(gè)方案,然后決定這種思想是否可行;如果可行,則應(yīng)該對(duì)其中一個(gè)或幾個(gè)方案作進(jìn)一步的改進(jìn)。
在生產(chǎn)設(shè)計(jì)階段中,與材料有關(guān)的主要問題是應(yīng)該把材料完全確定下來,使它們與現(xiàn)有的設(shè)備相適應(yīng),能夠利用現(xiàn)有設(shè)備經(jīng)濟(jì)地進(jìn)行加工,而且材料的數(shù)量能夠比較容易保證供應(yīng)。
在制造過程中,不可避免地會(huì)出現(xiàn)對(duì)使用中的材料做一些更改的情況。經(jīng)驗(yàn)表明,可采用某些便宜材料作為替代品。然而,在大多數(shù)情況下,在進(jìn)行生產(chǎn)以后改換材料要比在開始生產(chǎn)前改換材料所花費(fèi)的代價(jià)要高。在設(shè)計(jì)階段做好材料選擇工作,可以避免多數(shù)這樣的情況。在生產(chǎn)制造開始后出現(xiàn)了可供使用的新材料是更換材料的最常見的原因。當(dāng)然,這些新材料可能降低成本、改進(jìn)產(chǎn)品的性能。但是,必須對(duì)新材料進(jìn)行認(rèn)真的評(píng)價(jià),以確保其所有性能都滿足要求。應(yīng)當(dāng)記住,新材料的性能和可靠性很少像現(xiàn)有材料那樣為人們所了解。大部分的產(chǎn)品失效和產(chǎn)品責(zé)任事故案件是由于在選用新材料作為替代材料之前,沒有真正了解它們的長期使用性能而引起的。
通過對(duì)上述一些問題的分析,可以得出這些問題是沒有充分理由存在的結(jié)論。對(duì)這些問題的研究分析可以為避免這些問題的出現(xiàn)指明方向。盡管采用最好的材料選擇方法也不能避免發(fā)生產(chǎn)品責(zé)任訴訟,設(shè)計(jì)人員和工業(yè)界按照適當(dāng)?shù)某绦蜻M(jìn)行材料選擇,可以大大減少訴訟的數(shù)量。
從以上的討論可以看出,選擇材料的人們應(yīng)該對(duì)材料的性質(zhì),特點(diǎn)和加工方法有一個(gè)全面而基本的了解。

To improve the structure and function of the expansion of Taiwan vice based solidworks
Abstract
This topic through to analysis the ordinary machine with bench vise's organization, discovered that it cannot be the very good at clamping the sphere, the cylindrical work piece, but V shape mouth of the tongs may be the very good at clamping the cylindrical work piece. Therefore I have developed an especial series of V shape mouth of the tongs , which are better at clamping the different sizes of the cylindrical work pieces, thus it achieves the attire to clamp conveniently, raises the processing efficiency, improves the processing quality and the precision goal. Moreover, through to think the ordinary bench vise's function, discovered that besides supports on both sides the work piece, but can also act as the face plate, move v shape block, the adjustable spanner. Taiwan vice functionality can be expanded to reduce the number of tools, save processing time, cost savings, the purpose of lifting the temporary difficulties, but also so that Taiwan has been more fully vice use.
Keywords: Taiwan vice, V-shaped blocks, Crossing the platform, V-type mouth

一、選題的目的意義
機(jī)械加工中,臺(tái)虎鉗是較為常見的裝夾工具,它分機(jī)同和手用兩種, 都是利用兩鉗口作定位基準(zhǔn),靠絲扛、螺母?jìng)魉蜋C(jī)械力的原理。其結(jié)構(gòu)簡(jiǎn)單,裝夾迅速,所以被人們稱道。但是臺(tái)虎鉗也有其不足之處,如襲夾外形較為復(fù)雜和不規(guī)則工件時(shí),就力不從心了。主要原因是臺(tái)虎鉗鉗口是平直的, 不適于裝夾球形,特別是圓柱形工件。機(jī)加工時(shí)工件易位移,有時(shí)工件還會(huì)飛出機(jī)床臺(tái)面。為此,特對(duì)臺(tái)虎鉗的鉗口進(jìn)行結(jié)構(gòu)的改進(jìn)設(shè)計(jì),以滿足其使用功能的要求,使其更加的實(shí)用化。
利用普通臺(tái)虎鉗的特性,對(duì)其使用功能的拓展,是臺(tái)虎鉗的功能更加全面化。

臺(tái)虎鉗屬于夾具的一個(gè)類別,臺(tái)虎鉗的發(fā)明創(chuàng)造使得加工圓柱件時(shí)便得很方便,而且還省時(shí)省力,節(jié)省了人力物力,提高了加工效率、加工精度、產(chǎn)品質(zhì)量。其結(jié)構(gòu)簡(jiǎn)單,裝夾迅速,所以被人們稱道,在生產(chǎn)車間可以看到它的普遍適用性。
普通臺(tái)虎鉗由于其結(jié)構(gòu)的簡(jiǎn)單性,必定會(huì)在有些使用功能上有些缺陷,現(xiàn)在很多設(shè)計(jì)人員已經(jīng)研發(fā)出大量滿足特定功能或者使某一功能更加優(yōu)化的臺(tái)虎鉗。如快速加緊臺(tái)虎鉗、升降臺(tái)虎鉗、快速凸輪自鎖臺(tái)虎鉗等等。
臺(tái)虎鉗是靠夾緊力來加緊工件,來滿足加工的要求,是工件穩(wěn)定,減少加工誤差。另一方面,關(guān)于臺(tái)虎鉗夾緊下工件定位穩(wěn)定性的快速算法,也可以大力的幫助加工零件。
根據(jù)使用條件的不同,加工環(huán)境的不同,人們還會(huì)對(duì)臺(tái)虎鉗進(jìn)行進(jìn)一步的改進(jìn)創(chuàng)新,會(huì)有越來越多不同的結(jié)構(gòu)使臺(tái)虎鉗的使用功能多樣化、全面化。
三、主要研究?jī)?nèi)容
1.對(duì)普通臺(tái)虎鉗結(jié)構(gòu)的分析熟悉,利用三維軟件solidworks對(duì)其進(jìn)行實(shí)體造型設(shè)計(jì)。
2.利用普通臺(tái)虎鉗鉗口的開度可以調(diào)節(jié)以及兩塊鋼制鉗口表面的直線度、平面度、硬度、比較高的特點(diǎn),在對(duì)小件圓柱體材料進(jìn)行粗加工畫線時(shí),可以把它當(dāng)V形塊使用。
3. 普通臺(tái)虎鉗鉗口的夾緊力,用它來夾緊彈簧的鋼絲一端,配合其它工具就能繞制結(jié)構(gòu)簡(jiǎn)單的彈簧。
4. 利用普通臺(tái)虎鉗鉗口夾緊力的大小,可以校正不同規(guī)格的小鋼材。
5. 對(duì)臺(tái)虎鉗的鉗口進(jìn)行結(jié)構(gòu)的改進(jìn)設(shè)計(jì),以滿足其使用功能的要求,使其更加的實(shí)用化。
四、畢業(yè)論文(設(shè)計(jì))的研究方法或技術(shù)路線
1.對(duì)臺(tái)虎鉗的結(jié)構(gòu)熟悉分析,全面的了解臺(tái)虎鉗的結(jié)構(gòu)、工作原理。
2.結(jié)合參考書籍利用三維軟件solidworks對(duì)臺(tái)虎鉗的結(jié)構(gòu)進(jìn)行設(shè)計(jì)。
3為了某一項(xiàng)使用功能,對(duì)臺(tái)虎鉗的某個(gè)部位進(jìn)行改造。例如:鉗口的改進(jìn)設(shè)計(jì),以滿足圓柱件的夾緊、加工。
4臺(tái)虎鉗功能的拓展:當(dāng)V形塊使用、手工繞制彈簧、校正小鋼材
