Description

Technical Field

[0001] This utility model belongs to the field of boiler shell manufacturing technology, and specifically relates to an automated auxiliary manufacturing device for boiler shells. Background Technology

[0002] Currently, after metal sheets are continuously plastically deformed and rolled into boiler drums by a plate rolling machine, they are very prone to movement under gravity and their own rebound force, which can lead to misalignment or excessively wide joints at the boiler drum joints. This not only affects the welding process but also the quality of the weld after welding, thus affecting the boiler's performance and safety.

[0003] A search revealed a rotary auxiliary device for boiler welding, with prior art announcement number CN 222243364 U. This device uses a worm gear and worm wheel to drive a splined shaft, a first roller, and a second roller to rotate, thereby controlling the synchronous rotation of two sets of furnace cylinders placed on the first and second rollers. Simultaneously, the self-locking characteristic of the worm gear and worm wheel ensures that the furnace cylinders remain stationary after the first and second rollers stop rotating, facilitating welding. However, during welding using this device, operators need to continuously adjust the width of the boiler cylinder joints manually, leading to a decrease in welding speed.

[0004] A search revealed a welding device for boiler manufacturing with adjustable height, disclosed in patent application CN 222873675 U. This device uses a servo motor to move a threaded sleeve upwards or downwards simultaneously, thereby adjusting the height of the worktable. When the worktable reaches a designated position, a lifting assembly limits its movement to prevent displacement during welding. Simultaneously, a clamping assembly clamps and limits boilers of different sizes. However, the process of fixing or removing the boiler from the clamping assembly requires manual operation, and the clamping force is uncontrollable. This can easily lead to excessive clamping force damaging the boiler, or insufficient clamping force affecting welding stability. Summary of the Invention
