Technical Field

[0001] The present invention belongs to the field of automatic circumferential seam welding of cylinders, and specifically relates to an automatic circumferential seam welding device for cylinders. Background Art

[0002] The circumferential seams of cylinders are mostly welded manually. In fact, when the cylinder is too large during manual welding, various large tools, tooling and other equipment are also needed. Although the quality of manual welding is generally better because on-site evaluation can be carried out, skilled workers are required, and the handling and alignment of the cylinder need the participation of cranes and command and dispatch personnel, resulting in the inability to streamline the number of personnel involved, thus leading to extremely high cost. The cylinder itself is easy to roll, has a large mass, making alignment difficult and posing a greater risk. Therefore, an automatic circumferential seam welding device for cylinders is proposed.

[0090] The receiving arm 2354 rotates with the toothed ring 234, so that the welding head rotates around the cylinder body for one week for welding. The orientation of the fitting groove can prevent the receiving arm 2354 and the receiving frame 238 from contacting each other.

[0091] The specific implementation method is as follows: The motor four 35 on the movable vertical arm one 16 and the vertical arm 17 makes the control seat 36 and the assembly piece 19 approach or move away through the lead screw five 37. The assembly piece 19 drives the second clamping piece 41 and the first clamping piece 40 to approach and clamp a cylinder body. The motor four 35 on the movable vertical arm two 18 makes the control seat 36 and the assembly piece 19 approach or move away through the lead screw five 37. The assembly piece 19 drives the second clamping piece 41 and the first clamping piece 40 to approach and clamp another cylinder body. The first sprocket 21 controls the movable vertical arm two 18 to stand up so that the two cylinder bodies are butted, and the butted part of the two cylinder bodies is welded by the welding component.

[0092] It should be understood that in the development process of any actual implementation method, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without excessive experimentation, such development efforts will be a routine task of design, manufacturing, and production.

[0093] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
