50吨焊接滚轮架主动滚轮架设计
摘要
在焊接生产中,经常会遇到需要焊接变位及选择合适焊接位置的情况,针对这些实际需要,我们设计和研制了各种各样的焊接变位装置。焊接滚轮架就是一种能实现焊件自动变位的焊接辅助设备。它的动力驱动装置通过传动装置驱动主动滚轮转动,利用主动滚轮与圆筒类工件之间的摩擦力带动工件旋转实现变位,可实现工件的焊缝处于最理想的位置进行焊接,从而大大提高焊缝的焊接质量和生产率,并大大降低焊工劳动强度。
本次设计的题目是50吨焊接滚轮架主动滚轮架的设计,要求可根据工件的直径调节滚轮的中心距,整个机械系统简单可靠,操作方便,经济适用。本次设计的主要内容包括:主动滚轮架的底座、主动滚轮机构、减速器机构等的机械设计、装配图和零件图设计以及编写设计说明书。本文简要地介绍了50吨滚轮架设计的主要内容,包括设计题目的分析、总体方案的确定、电机的选择、传动比的分配、主动滚轮机构的设计以及主要传动件的设计校核等内容。本次设计的主动滚轮架与从动滚轮架是相互独立的,使用时可根据焊件的重量和长度进行任意组合,因此使用方便灵活,对焊件的适应性很强。

THE DRIVING ROLLER CARRIER DESIGN OF
A FIFTY TONS WELDING ROLLER CARRIER
ABSTRACT
In welding production, it mon for us to turn the weldment and choose the appropriate welding position. According to the actual needs, we have designed and developed a variety of welding displacement equipment. For example,welding roller carrier is one of such kinds of welding auxiliary equipment which can realize welding displacement automatically. Its driving device takes the driving roller rotation through the transmission device, and with the help of the friction between the cylinder weldment and the driving roller ,it can realize the rotation and displacement of the workpiece, which can ensure the welding line in the ideal position for welding, so as to improve the welding quality and productivity dramatically, and reduce the labor intensity of welders significantly.
The topic of this thesis is the driving roller carrier design of a fifty tons welding roller carrier. The center distance of its rollers should be adjustable according to the diameter of the workpiece and its mechanical system should be simple, reliable, easy to operate, affordable. The main content of my task includes: the driving roller base and mechanism design, the retarding mechanism design, assembly drawing and part drawing design and writing the design specification. The design process of a 50 tons welding roller carrier is briefly introduced in this paper. The main content includes: the design subject analysis, t
