[0043] When the above structure is in use, the first hydraulic rod 320 contracts and drives the arc adjustment frame 318 to move by driving the hanging ear 319, and then the arc adjustment frame 318 drives the first arc bar 317 to move, so that the first arc bar 317 drives the welding head 314 to rotate around the first hinge column 311 through the driving frame 316 in cooperation with the first hinge frame 312 and the sleeve 313 until the welding head 314 is set at 45°. At this time, the micro electric push rod 315 drives the welding head 314 to move to the welding position until the welding head 314 is attached to the position to be welded of the mutually perpendicular circular tubes.

[0047] When the above structure is in use, when the two mounting frames 201 need to be set vertically, the adjustment frame 401 and the second hinge column 402 are pulled upward on the inner wall of the second hinge frame 403 through the handle until the second hinge column 402 is located at the top of the inner wall of the second hinge frame 403. At this time, the adjustment frame 401 is rotated around the second hinge column 402 until the adjustment frame 401 is blocked by the block 404. At this time, the adjustment frame 401 and the first end plate 101 remain vertical, that is, the two mounting frames 201 remain vertical.

[0048] A method for using an automated pipe welding machine according to the claims, comprising the following steps:

[0049] S1. Adjust the state of the clamping assembly according to the welding type. That is, when welding coaxial circular tubes, the two mounting brackets 201 are arranged in parallel. When welding mutually perpendicular circular tubes, adjust the mounting bracket 201 at one end of the first end plate 101 to a perpendicular state with respect to the first end plate 101.

[0050] S2. Rotate the driving column 202, and make the driving column 202 drive the rotary arm 203 to rotate, so that the two clamping arms 207 move relative to each other and clamp the round pipe to be welded;

[0051] S3. When welding mutually perpendicular round tubes, the first hydraulic rod 320 drives the hook 319 to cause the arc adjustment frame 318 to contract, so that the arc adjustment frame 318 cooperates with the first arc bar 317 and the drive frame 316 to drive the first hinged frame 312 and the welding head 314 to rotate, so that the welding head 314 is tilted 45 degrees. Then, the micro electric push rod 315 drives the welding head 314 to fit the welding position.

[0052] S4. The driving motor drives the active gear 305 to rotate, so that the active gear 305 drives the half gear ring 308 to rotate through the first driven gear 306 and the second driven gear 307, and then the half gear ring 308 drives the welding head 314 to rotate through the connecting plate 309, and welds around the position to be welded. When welding mutually perpendicular circular pipes, the second hydraulic rod 324 synchronously drives the first guard plate 301, the second guard plate 302, the first partition plate 303 and the second partition plate 304 to move, and synchronously drives the welding head 314 to move, so that the welding head 314 rotates around the mutually perpendicular circular pipes to be welded.

[0053] Working principle: When in use, the invention requires that when welding coaxial circular tubes, both mounting brackets 201 are arranged parallel to the first end plate 101 and the second end plate 102. At this time, the two circular tubes to be welded are placed between the two clamping arms 207 of the two clamping assemblies. Then, the driving column 202 is rotated, and the driving column 202 drives the rotary arm 203 to rotate, so that the rotary arm 203 cooperates with the articulated arm 204 to drive the guide slider 205 to move relative to the guide slot 206, so that the guide slider 205 drives the clamping arm 207 to clamp the circular tube, and the position to be welded corresponds to the position of the welding head 314.

[0054] After the clamping is completed, the micro electric push rod 315 drives the welding head 314 to approach the position to be welded, and then the driving motor drives the driving gear 305 to rotate, and the driving gear 305 cooperates with the first driven gear 306 and the second driven gear 307 to drive the half ring gear 308 to rotate, wherein the number of the second driven gears 307 is two, which makes the half ring gear 308, which is not a complete circular structure, always keep in meshing state with one second driven gear 307. By providing the second arc strip 325 and the guide groove 326, the rotation stability of the half ring gear 308 can be improved. When the half ring gear 308 rotates, the half ring gear 308 cooperates with the first hinge column 311, the sleeve 313 and the sleeve 313 through the connecting plate 309 to drive the welding head 314 to rotate around the position to be welded until the welding operation is completed.

[0055] When welding mutually perpendicular circular pipes, since the welding position is not a regular circular structure, but a ring structure with a distance in the horizontal direction, the adjusting frame 401 and the second hinge column 402 are pulled upward on the inner wall of the second hinge frame 403 by the handle until the second hinge column 402 is located at the top of the inner wall of the second hinge frame 403, and the adjusting frame 401 is rotated around the second hinge column 402 until the adjusting frame 401 is blocked by the stopper 404. At this time, the adjusting frame 401 and the first end plate 101 are kept in a vertical state, that is, the two mounting frames 201 are kept in a vertical state, and then the two circular pipes to be welded are placed between the two clamping arms 207 of the two sets of clamping assemblies, and the driving column 202 is rotated, and the driving column 202 drives the rotary arm 203 to rotate, so that the rotary arm 203 cooperates with the hinge arm 204 to drive the guide slider 205 to move relative to each other along the direction of the guide slot 206, so that the guide slider 205 drives the clamping arm 207 to clamp the circular pipe;

[0056] After the clamping is completed, the first hydraulic rod 320 contracts and drives the arc adjustment frame 318 to move by driving the hanging ear 319, thereby causing the arc adjustment frame 318 to drive the first arc bar 317 to move, and when the first arc bar 317 moves, the first arc bar 317 will drive the first hinge frame 312 to rotate through the driving frame 316, thereby causing the first hinge frame 312 to cooperate with the sleeve 313 to drive the welding head 314 to rotate around the first hinge column 311 until the welding head 314 is set at 45 degrees. At this time, the micro electric push rod 315 drives the welding head 314 to move to the welding position until the welding head 314 is attached to the position of the mutually perpendicular circular pipe to be welded. At this time, the driving motor drives the driving gear 305 to rotate, and causes the driving gear 305 to cooperate with the first driven gear 306 and The second driven gear 307 drives the half gear ring 308 to rotate. When the half gear ring 308 rotates, the half gear ring 308 cooperates with the first hinge column 311, sleeve 313 and sleeve 313 through the connecting plate 309 to drive the welding head 314 to rotate around the welding position. At the same time, the second hydraulic rod 324 drives the second guard plate 302, the second partition plate 304, the first partition plate 303 and the first guard plate 301 to move on the surface of the first guide column 322 and the second guide column 323, and adjusts the position of the welding head 314, so that the welding head 314 can move horizontally synchronously during the process of rotating around the circular pipe, so that the welding head 314 always moves around the welding position of the two circular pipes perpendicular to each other until the welding operation is completed, thereby achieving the purpose of being suitable for welding between two vertical pipes.
