摘要: 焊接裝備就是在焊接生產(chǎn)中與焊接工序相配合，有利于實(shí)現(xiàn)焊接生產(chǎn)機(jī)械化、自動(dòng)化，有利于提高裝配焊接質(zhì)量，促使焊接生產(chǎn)過(guò)程加速進(jìn)行的各種輔助裝置和設(shè)備。焊接工裝在焊接機(jī)械化中也扮演著重要的角色，采用工裝夾具，工件定位迅速，裝夾方便，省力，減輕了焊件裝配定位和夾緊時(shí)的繁重體力勞動(dòng)；焊件的翻轉(zhuǎn)可以實(shí)現(xiàn)機(jī)械化，變位迅速，使焊接條件較差的空間位置焊縫變?yōu)楹附訔l件較好的平焊位置焊縫，勞動(dòng)條件改善，同時(shí)也有利于提高焊縫的質(zhì)量。在裝配定位焊件時(shí)，如果不使用工裝夾具，即使焊接組合件由兩三個(gè)零件組成的，欲保證各零件精確的相對(duì)位置也是很難的。同時(shí)，在焊接過(guò)程中，焊接件一般會(huì)由于受熱不均等原因而發(fā)生焊接變形，尤其是復(fù)雜的焊接結(jié)構(gòu)，其變形有時(shí)會(huì)無(wú)法消除，這樣就會(huì)影響以后的裝配工作。采用工裝夾具，不僅可以保證焊接時(shí)工件間的相對(duì)正確位置，而且可以防止和減少工件的焊接變形。批量生產(chǎn)的時(shí)候，這種優(yōu)點(diǎn)就更加明顯，可以穩(wěn)定焊接件的質(zhì)量，減少次品的產(chǎn)生。焊接滾輪架是借助主動(dòng)滾輪與焊件之間的摩接力帶動(dòng)焊接旋轉(zhuǎn)的變位機(jī)械。焊接滾輪架主要用于筒形焊件的裝配與焊接。焊接滾輪架按結(jié)構(gòu)形式分為兩類：第一類是長(zhǎng)軸式滾輪架。第二類是組合式滾輪架。本文主要對(duì)組合式12T焊接滾輪架進(jìn)行設(shè)計(jì)，并對(duì)軸、鍵等主要構(gòu)件進(jìn)行了校核。結(jié)果表明各主要部件符合要求。該滾輪架結(jié)構(gòu)簡(jiǎn)單，使用方便靈活，對(duì)焊件的適應(yīng)性很強(qiáng)。設(shè)計(jì)中充分的考慮了滾輪架的合理性和經(jīng)濟(jì)性等因素。

Abstract : Welding equipment is a machine which is used in welding production and welding processes, and it is conducive to welding production mechanization and automation, to improving assembly welding-quality. Then it could prompte to speed up the process of welding production of the various assistive devices and equipment. Welding fixtures also play an important role in Mechanized welding, with fixture, positioning quickly, easy clamping, effort, reduce the weldment assembly positioning and the clamping the heavy manual labor; flip the weldments can be mechanized, rapid deflection, and make the spatial location weld of poor conditions into a better position weld , improved working conditions, at the same time it help to improve the quality of the weld. When in the assembly weldments of positioning, if you do not use the fixture, even if the welding assembly formed by the two or three parts, to ensure the accuracy of the relative position of each part is very difficult. At the same time, in the welding process, the Welding parts generally would occurred welding deformation as uneven heating and other reasons, especially with the welded structures was complex, sometimes its deformation can not be eliminated, this will affect the future work of assembly. With fixture, not only can ensure the correct relative position in welding between the workpiece, but also can prevent and reduce the welding deformation of the workpiece. When in the mass production, this advantage become more apparent, can stabilize the quality of welded parts, reduce the production of defective. Welding roller standing by structural form is divided into two categories : the first category is long axis-wheel frame. the second category is modular roller frame. In this paper, twelve pairs of modular T-welded wheel for the design, as well as axial, bond and other main component of checking. The results showed that the main components to meet the requirements. The roller frame structure is simple, flexible, adaptive welded pieces of a strong, which is the most widely used form of the structure. And it could be fully considered the roller frame reasonable and economic, and other factors.
