作为本实施例的优选方案：导向定位机构49分别包括第一伺服电机491、安装槽492、内螺纹套管493、双向丝杆494、第一锥齿轮495、第二锥齿轮496和刷辊497，安装槽492固接于焊剂漏斗44一侧的顶部，安装槽492一侧的中间位置处设有第一伺服电机491，第一伺服电机491的输出端设有第一锥齿轮495，安装槽492内部的中间位置处套设有双向丝杆494，双向丝杆494外侧的两端套设有螺纹适配的内螺纹套管493，两组内螺纹套管493相互远离的一端固接有刷辊497，双向丝杆494外侧的中间位置处设有与第一锥齿轮495相互啮合的第二锥齿轮496。
作为本实施例的优选方案：移动轨道1背面一端的一侧设有支架，且支架与延伸导轨31固接，焊接小车2的顶部设有固定槽，且固定槽的顶部设有与机身51相互贴合的限位座，提供移动轨道1背面的固定支架，促使焊接小车2在移动时同时通过移动轨道1和固定支架的延伸导轨31进行导向限位。
作为本实施例的优选方案：送丝机构43的一侧设有导丝管，且导丝管的一侧设有法兰盘，延伸导管42的一侧设有连接头，且连接头与法兰盘固接，便于使延伸导管42稳定的与导丝管相互结合，促使送丝机构43的焊丝可稳定的在延伸导管42内输送。
作为本实施例的优选方案：吸风机46的顶部设有导管，延伸导管42底部的一侧设有收料槽，且收料槽与导管相互连通，吸风机46的底部设有斜型吸料口，且斜型吸料口与焊枪45相互对应，便于对吸风机46吸收的粉尘进行收集，增加后续回收处理工作的便捷性，利用斜型吸料口与焊枪45的位置对应，提高焊枪45引出烟尘的吸收率。
作为本实施例的优选方案：延伸导管42和焊剂漏斗44与焊枪45相互连通，焊剂漏斗44的顶部设有加料口，且加料口的顶部设有密封盖，便于对焊机进行加注和封堵，以防焊机的粉尘跑出。
作为本实施例的优选方案：导轮32与延伸导轨31呈限位滑动结构相互适配，延伸导轨31和移动轨道1呈不同的垂直面，促使延伸导管42移动的同时可在导轮32和延伸导轨31以及伸缩杆33的限位配合下水平移动，并利用延伸导轨31与移动轨道1呈不同的垂直面，促使结构在移动时不会互相妨碍和部件相撞。
作为本实施例的优选方案：安装槽492内部的中间位置处对称设有轴承座，双向丝杆494套设于轴承座的内侧，安装槽492的两端设有限位套，安装槽492内部的一侧设有滑槽，且滑槽的内侧对称设有与内螺纹套管493固接的滑块，增加内螺纹套管493的限位导向功能，促使两组内螺纹套管493可稳定的向外展开或向内收缩水平移动。
作为本实施例的优选方案：安装槽492一侧的中间位置处设有位移传感器，两组刷辊497的外侧设有防滑纹，便于感知492整体的位置是否出现错位，提高两组刷辊497与容器筒体贴合的摩擦力和稳定性。
实施例1，如图1-4所示，当焊接小车2带动延伸导管42和机头41伸入容器筒体内时，可利用第二伺服电机55的启动带动螺纹杆53旋转，促使机身51内的内螺纹槽52随着螺纹杆53的旋转以及伸缩导管54的导向进行升降调节，从而使延伸导管42的高度得到调整，适配不同直径的容器筒体，增加装置的泛用性。
实施例2，如图1-4所示，当焊接小车2带动延伸导管42和机头41进行位移时，可利用延伸导管42下方架设的延伸导轨31及导轮32作为导向结构，促使延伸导管42移动的同时带动伸缩杆33和导轮32在延伸导轨31内限位滑动，提高延伸导管42整体移动的稳定性，防止焊接小车2和定位焊接***4位移调节时颤动，并利用伸缩杆33的伸缩特性，可配合升降调节机构5的升降调节一同升降，增加装置结构之间的协调性。
工作原理：当装置使用时，可通过焊接小车2在移动轨道1进行移动调节，促使焊接小车2整体带动延伸导管42及机头41伸入需要埋弧焊接的容器筒体内，此时便可利用送丝机构43将焊丝在延伸导管42内自动送丝，促使焊丝直接从延伸导管42导入焊枪45，促使焊枪45配合焊剂漏斗44的焊剂以及容器筒体的转动进行焊接工作；
其次，在焊接工作期间可利用第一伺服电机491的启动带动第一锥齿轮495和第二锥齿轮496相互啮合转动，迫使第二锥齿轮496带动双向丝杆494旋转，随着双向丝杆494的旋转可使两组内螺纹套管493向外展开，从而使内螺纹套管493带动刷辊497根据不同大小容器的直径进行展开调节，最终使两组刷辊497与容器筒体内部的两侧壁与之贴合，此时便可对筒体进行导向限位，提高筒体旋转的稳定性，而在焊枪45自动焊接期间可利用吸风机46的启动对容器筒体焊缝处进行吸尘工作，从而对焊枪45焊接引发的烟尘快速吸收，避免烟尘飞出容器外部与空气混合；
最后，当焊枪45焊接后，可通过焊接小车2的位移，将两组刷辊497与焊缝处贴合，此时便可随着筒体的旋转，利用刷辊497的辊压将焊缝未完全吸收的粉尘刷落，并利用吸风机46进行吸收，而在刷辊497辊压的同时可通过光学检测仪48的启动对焊缝进行自动化检测，从而使装置自动对焊缝焊接的质量进行质检工作。
最后应当说明的是，以上内容仅用以说明本发明的技术方案，而非对本发明保护范围的限制，本领域的普通技术人员对本发明的技术方案进行的简单修改或者等同替换，均不脱离本发明技术方案的实质和范围。
