And finally, welding a small section of the circumferential weld of the shell ring and the seal head by the welding robot 3, so that the seal head and the shell ring can be driven to synchronously rotate, and the circumferential weld between the shell ring and the seal head can be welded by the welding robot 3.
In conclusion, the cylindrical shell section and end socket assembling and welding device provided by the embodiment hoists the cylindrical shell section and the end socket through the hoisting tool mechanism 1, compared with the manual operation in the prior art, the forward and backward movement of the cylindrical shell section and the end socket is not hoisted by a crane any more, the labor intensity is greatly reduced, the production efficiency of assembling and welding is improved, and the production safety is improved; fix and drive shell ring and head rotation through rotatory supporting platform 3 to the shell ring to welding robot 2 welds the circumferential weld between shell ring and the head, so that realize mechanized production. In particular, the inner circle-expanding mechanism 31 arranged on the rotary supporting platform 3 expands the cylinder section to fix the cylinder section to the rotary supporting platform and ensure the stability of the cylinder section and the seal head in assembly, so that the cylinder section and the seal head stably rotate along with the rotary supporting platform 3 to ensure the stability of the cylinder section assembly in welding. Simultaneously, the accessible presss from both sides tight frock 4 outward and leads the group to the head to can realize that shell ring and head are outside tight, avoid between shell ring and the head group to the time or the dislocation of position when welding, reduce the misalignment amount between the two, the workman need not to climb to the workstation again and goes to group and the centre gripping, only needs operating button can accomplish the group of shell ring to reach the welding, further reduces workman's intensity of labour, improves production efficiency.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
