1.0吨普通座式焊接变位机工装设计

摘要

焊接变位机也已成为制造业的一种不可缺少的设备，在焊接领域把它划为焊接辅助机。就型式系列和品种规格而言，已问世的，约有十余个系列，百余个品种规格，正在形成一个新兴行业。但是，有关焊接变位机的基本概念、型式与分类、主要技术参数等，存在不统一的问题。

本题目是设计能载重1.0t工件，进行全位置焊接的变位机械。主要内容是关于焊接时机械的回转翻转的控制、电机选择、减速器的选择、各个轴和齿轮轴承的确定以及校核等等。

设计的具体过程是根据预定的载荷和要求的焊接速度从而确定设备所需要的电机类型，包括：电机的转速、额定功率、电压电流等，在此基础上计算轴的尺寸和相应配件的型号，并且对其进行相关的强度、使用寿命等的校核，然后对一些外购件也进行选择。最后使用CAD软件将相关的零件图。总装图绘制出来。

选用的方法主要是机械设计的相关知识，使用到的有材料力学、金属工艺学、Autocad等。

Abstract

Welding conjugation plane has become an indispensable manufacturing equipment , which is zoned welding assistant engine in the welding area. Patterns and varieties of specifications on the series, has been developed, some over 10 series, more than 100 varieties of specifications, a newly emerging industries. However, the welding machine conjugation basic concepts, patterns and classification, the main technical parameters, there are not uniform.

This topic is designed to load 1.0t working, welding locations throughout the conjugation machinery. Mainly on the subject of welding, mechanical rotation turnover of control, the electrical options, reducer selection, various axle and the wheel bearings and determine accuracy, and so on.

The design process is based on specific target load and speed requirements of welding equipment to determine the type of electrical needs, including : the rotational speed electrical, rated power, voltage, current and on the basis of the calculation of axle size and corresponding accessories models, and their associated intensity, and the useful life of accuracy, then for some purchases were also chosen. Finally related to the use of CAD software components map. GAD mapping out.

The method chosen mainly mechanical design relevant knowledge, the use of the material mechanics, metal crafts science, Autocad.

Keyword : welding conjugation machines, mechanical design.
