After the positioning point welding is completed, the air bag 343 is deflated to release the clamping jaws 342, after the circle holding driving device 43 is confirmed to retreat in place, the chuck 34 and the circle holding mechanism 4 are retreated to the original position, the chuck 34 is turned over to the horizontal state, and the chuck 34 is started to rotate 360 degrees to automatically reset.

10. And (3) after the tank body which is subjected to butt joint is transported to the next station through the transport vehicle, repeating the step (1) and preparing for clamping the next workpiece.

In the tank type container assembly table, the chuck can be turned over between the feeding position and the working position through the turning mechanism, and the chuck can rotate for 360 degrees around the axis of the chuck through the rotating mechanism, so that the cylinder body and the end enclosure are driven to rotate together. According to the assembly table, the welding operation position can be set to be a certain fixed position located on the outer side of the circumference of the butt joint of the cylinder body and the end socket, and when the part to be welded of the end socket and the cylinder body rotates to the welding operation position, the part to be welded is welded. After the end socket and the barrel are fixedly held by the chuck, in a period of rotating 360 degrees, the parts needing to be welded on the whole circumference of the butt joint of the end socket and the barrel can sequentially reach the welding operation positions to complete welding, so that the production efficiency is improved; in the whole welding operation process, the operating personnel do not need to change the operation position and do not need to ascend, and the labor intensity is reduced. The invention improves the automation level of the whole machine, effectively improves the production efficiency and the operation safety, reduces the labor intensity of workers and lays a foundation for automatic assembly design.

While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
