摘  要
　　　隨著現(xiàn)代計(jì)算機(jī)技術(shù)的高速發(fā)展，高新技術(shù)在現(xiàn)代設(shè)計(jì)中應(yīng)用的越來(lái)越廣泛，如CAD/CAM/CAE等計(jì)算機(jī)輔助設(shè)計(jì)方法在國(guó)際上應(yīng)用越來(lái)越普遍。這些設(shè)計(jì)方法不但提高了設(shè)計(jì)速度，而且設(shè)計(jì)出來(lái)的產(chǎn)品更加可靠美觀，并且可以節(jié)省大量的人力、物力，大大提高產(chǎn)品的競(jìng)爭(zhēng)力。在生產(chǎn)實(shí)際當(dāng)中，回轉(zhuǎn)分度盤(pán)的應(yīng)用非常廣泛，它是機(jī)床中傳遞力與運(yùn)動(dòng)的重要部件。本文是針對(duì)數(shù)控機(jī)床的迅速發(fā)展，應(yīng)用計(jì)算機(jī)輔助設(shè)計(jì)的方法設(shè)計(jì)一種氣動(dòng)斜楔式回轉(zhuǎn)分度盤(pán)。
　　　本次設(shè)計(jì)中，采用三維CAD以及動(dòng)態(tài)仿真分析等現(xiàn)代設(shè)計(jì)方法建立了回轉(zhuǎn)分度盤(pán)的實(shí)體模型、完成結(jié)構(gòu)裝配及進(jìn)行裝配仿真，并對(duì)三爪動(dòng)力回轉(zhuǎn)分度盤(pán)的工作原理及其設(shè)計(jì)計(jì)算進(jìn)行了分析。通過(guò)力的平衡方程,得出夾緊力與推拉力的關(guān)系。在設(shè)計(jì)過(guò)程中，首先對(duì)回轉(zhuǎn)分度盤(pán)的原理方案進(jìn)行了選定，根據(jù)原理進(jìn)行回轉(zhuǎn)分度盤(pán)的結(jié)構(gòu)設(shè)計(jì)。然后根據(jù)主參數(shù)進(jìn)行回轉(zhuǎn)分度盤(pán)的力學(xué)分析，并對(duì)回轉(zhuǎn)分度盤(pán)的精度進(jìn)行了分析。最后，根據(jù)結(jié)構(gòu)的設(shè)計(jì)進(jìn)行了回轉(zhuǎn)分度盤(pán)的裝配工藝設(shè)計(jì)及仿真。
　　　裝配工藝規(guī)劃是產(chǎn)品裝配設(shè)計(jì)的主要內(nèi)容，是產(chǎn)品生產(chǎn)過(guò)程中一個(gè)極其重要的環(huán)節(jié), 直接影響到產(chǎn)品的最終質(zhì)量。因此在回轉(zhuǎn)分度盤(pán)設(shè)計(jì)中，采用Solidworks軟件，進(jìn)行建模仿真，根據(jù)回轉(zhuǎn)分度盤(pán)的結(jié)構(gòu)裝配制定出裝配工藝。

Rotary indexing fixture design and assembly process planning
Abstract
　　　With the rapid development of modern computer technology, high-tech applications in modern design more and more extensive computer-aided design methods such as CAD / CAM / CAE applications in the international arena is becoming increasingly common. These design methods not only improve the design speed, and design products more reliable and beautiful, and can save a lot of manpower, material, greatly improving the competitiveness of their products. In which the actual production, rotary indexing plate is widely used, it is an important component of the force and motion passed in the machine. This article is for the rapid development of CNC machine tools, the application of computer-aided design methods to design a pneumatic wedge rotary indexing plate.
     In this design, the use of 3D CAD, as well as dynamic simulation analysis of modern design methods to establish a solid model of the rotary indexing plate to complete the structural assembly and assembly simulation, and three-jaw power rotary indexing plate working principle and design calculations were analyzed. Through the force balance equation, draw the clamping force and the push pull relationship. In the design process, the first principle of rotary indexing plate program selected according to the principles of structural design of rotary indexing plate. And mechanical analysis of the main parameters of rotary indexing plate, and the accuracy of rotary indexing plate is analyzed. Finally, according to the design of the structure of a rotary indexing plate assembly process design and simulation.
    Assembly process planning is the main content of the product assembly design, is an extremely important link in the production process, a direct impact on the final quality of the product. Rotary indexing plate design using Solidworks software, modeling and simulation to develop a structural assembly of the rotary indexing plate assembly process.

Key Words: Rotary indexing;assembly process; Solidworks
