一种用于氩弧焊接环形焊缝的双侧同步涨紧机构
本专利技术属于航空发动机零部件制造
，特别是涉及一种用于氩弧焊接环形焊缝的双侧同步涨紧机构。
技术介绍
目前，通过氩弧焊接方式焊接环形焊缝时，通常需要用到一个简易的工件涨紧机构，该工件涨紧机构内的涨块会同时涨紧焊缝两侧的工件，从而完成焊缝两侧工件的定位。但是，当焊缝两侧工件的内径不一致时，涨块在涨紧工件过程中，会导致焊缝两侧工件出现不同轴的现象，进而引起焊接错边，而且错边也不均匀，最终影响到焊接质量。
技术实现思路
针对现有技术存在的问题，本专利技术提供一种用于氩弧焊接环形焊缝的双侧同步涨紧机构，当焊缝两侧工件的内径不一致时，工件涨紧后能够保证焊缝两侧工件的同轴度，有效避免焊接错边的发生，使焊接质量得到明显提高。为了实现上述目的，本专利技术采用如下技术方案：一种用于氩弧焊接环形焊缝的双侧同步涨紧机构，包括支座、左盖板、右盖板、左涨块、右涨块、拉锥及压锥；所述支座为圆盘形结构，所述左盖板及右盖板均为圆环形结构，左盖板和右盖板对称固装在支座两侧，且支座、左盖板及右盖板同轴设置；所述支座与左盖板之间开设有若干左涨块安装导向孔，支座与右盖板之间开本文档来自技高网...
