And starting the fourth cylinder 19, enabling the second elastic clamping jaw 20 to move downwards under the thrust of the fourth cylinder 19, enabling two ends of the second elastic clamping jaw 20 to firstly contact the circumferential surface of the end cover 21, enabling the second elastic clamping jaw 20 to deform and expand under the pressure until the extension length of the piston end of the fourth cylinder 19 is kept unchanged after the circumferential surface of the end cover 21 is completely attached to the second elastic clamping jaw 20, and enabling the roller 24 and the circumferential surface of the end cover 21 to be in rolling fit state all the time in the whole process. First and second resilient jaws 18, 20 cooperate to clamp end cap 21. And step four, adjusting the height of the piston end of the third hydraulic cylinder 14, changing the height of the end cover 21 to enable the circle center of the end cover 21 and the circle center of the longitudinal section of the shell 13 to be located on the same horizontal plane, starting the third cylinder 16 to push the end cover 21 to move towards the end face of the shell 13 until the extending length of the piston of the third cylinder 16 is kept unchanged after the end cover 21 is attached to the end face of the shell 13. The clamping of the shell is completed, and the subsequent welding work can be carried out.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
