75公斤焊接滚轮支架要点分析.doc

75公斤焊接滚轮架设计 摘 要 近年来，焊接工业得到了很快的发展，焊接设备也相继出现，各种焊接支架也得到了运用，在圆形工件内外环缝的焊接中组合式焊接滚轮架很受青睐，慢慢的取代长轴式、固定式等焊接滚轮架获得了广泛的应用,如何设计较好使用的滚轮架仍值得探讨。 随着生产的自动化，滚轮架在生产中的地位也日益突出。目前国外众多的焊接设备制造厂都在生产焊接滚轮架。产品规格型号多，结构差别也很大，各自有着不同的用途，有不同的特点。国内的重型焊接滚轮架用户则主要集中在大型石油化工、电站设备制造等行业上。使用的焊接滚轮架来自不同的国家。 焊接滚轮架是借助工件与主动滚轮间的摩擦力来带动工件旋转的机械装置,主要用于回转体工件的装配与焊接。本次设计题目是一台75公斤焊接滚轮，主动滚轮与从动滚轮架各自独立，二者可根据工件的重量、长度任意组合。使用灵活，适应性强，是目前最广泛的一种结构形式。 其设计的主要内容包括：75公斤焊接滚轮架的底座，主动滚轮机构、从动滚轮机构等的机械设计、装配图和零件图设计。对滚轮架、调整方式、传动方式等可采用不同的设计方案。整个机械系统应简单可靠，操作方便、经济适用。编写相应的设计说明书。 关 键 词：焊接，滚轮架，可调式，调速 DESIGN OF 75kg WELDING ROLLER CARRIER ABSTRACT In recent years, the welding industry has been rapidly developing, welding equipment has been developing. A kind of welding stent has been used。Cylinder part in the ring and outside the welding seam, and modular welding wheel-replace-long axis, welding and other fixed-wheel planes, access to a wide range of applications。How to design better use of the wheel-is still worth exploring. Wheel-welding machine as part of disciplines and with other disciplines are also linked to。 With the automation of production, wheel-in production has become more prominent position。The current number of domestic and international welding equipment factory in the production of welding wheel。Specifications models, structural differences, each suitable for different purposes, have different features。Chinas heavy welding wheel-users mainly concentrated in the large-scale petrochemical, power station equipment manufacturing, heavy equipment manufacturing industry。 The use of welding wheel-come from different countries The welding roller carrier is a mechanic divies to make the workpiece to rotate by the friction between the workpiece and the initiative roller. It mostly used in the assembly and welding of the turning workpiece. This thesis is the design of a welding roller carrier for 100 ton, which have independent initiative roller and driven roller. The two roller could be comminated necessarily bas
