3吨头尾架式翻转机设计

摘 要

焊接装备就是在焊接生产中与焊接工序相配合，有利于焊接生产实现机械化，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。焊接翻转机是焊接变位机械的一种，是将工件绕水平轴转动或倾斜，从而使之处于有利于装焊位置的焊件变位机械，主要用于梁、柱、框架等结构的焊接。焊接翻转机的种类较多，常见的有头尾架式、框架式、转环式、链条式、推拉式等。焊接翻转机结构简单，操作方便，工作效率高、工作质量好，可实现360度回转。因此，焊接翻转机广泛应用于化工、铁路交通、冶金等工业部门的自动焊接系统。
本次设计题目是3吨头尾架式翻转机，结构形式与车床类似，其头架为驱动端，可单独使用，利用安装在头架卡盘上的夹具，可为短小的工件翻转变位。翻转机尾架可在轨道上行走，便于根据工件的长度来调节与头架的距离。
本次设计考虑了翻转机的合理性和经济性等因素。设计的主要内容包括：翻转机头架的机座、回转机构、工作台等的机械设计、装配图和零件图设计，针轮摆线减速机和电机的选型等。该翻转机结构简单，操作方便，对焊件的适应性很强。

关 键 词：焊接，翻转机，头架，尾架
 

3 TONS HEAD AND TAIL FLIP MACHINE FRAME DESIGN

ABSTRACT

Welding equipment is all kinds of auxiliary equipment ,which is always combined with welding procedure in welding process so as to realize welding production mechanization, automation and improve welding quality and productivity. Welding turnover is one of welding displacement equipment, which takes the workpiece rotating around the horizontal axis in order to ensure the welding line in the ideal position for welding .And it is mainly used for beams, columns, frames and other welding structures.There are many kinds of welding tilter, such as the head to tail frame, frame type, ring type, chain type, push-pull type etc. Welding turnover device has simple structure, convenient operation, high efficiency, good quality of work, and can achieve 360 - degree rotation. Therefore, turnover of welding is widely used in chemical industry, railway transportation, metallurgical and other industrial departments of automatic welding system.
This design topic is 3 tons head to tail posture turnover similar to a lathe, its head ,as the driving device, can be used separately, which can be used for the displacement of small and short workpiece with the help of jig installed on the chuck head frame. The tail frame can walk on the track, in order to adjust the distance with the head frame according to the length of the workpiece.
This design takes many factors into consideration. For example, the design of the turnover should be reasonable and economic. The main content of the design include: the headstock base of the turnover design, slewing mechanism design, workbench design ,etc . and assembly drawing and part drawing design, needle wheel cycloid reducer and motor selection, etc. The turning machine structure is simple, easy to operate, and its adaptability for weldment is very strong
