自调式焊接滚轮架设计毕业设计

摘要

焊接装备就是在焊接生产中与焊接工序相配合，有利于实现焊接生产机械化，自动化，有利于提高装配焊接质量，促使焊接生产过程加速进行的各种辅助装置和设备。焊接滚轮架是借助主动滚轮与焊件之间的摩接力带动焊接旋转的变位机械。焊接滚轮架主要用于筒形焊件的装配与焊接。焊接滚轮架按结构形式分为两类：第一类是长轴式滚轮架。第二类是组合式滚轮架。本文主要对自调式式20T焊接滚轮架进行设计，并对轴、键等主要构件进行了校核。结果表明各主要部件符合要求。该滚轮架结构简单，使用方便灵活，对焊件的适应性很强。设计中充分的考虑了滚轮架的合理性和经济性等因素。

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 roller is used initiative and welding pieces of the wheel between the Mount relay driven welding rotating mechanical deformation. Welding roller stands for the main pieces of tube welding and welding assembly. 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, twenty 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.

Key words：weld, frock clamp, turning rolls; check; rationality
