[0033] Personnel in the technical field can understand that, the third screw rod 603 is driven to rotate by the output end of the third servo motor 605, so that the two groups of fourth clamping members are moved closer to or away from each other; the sixth screw rod 607 is driven to rotate by the output end of the sixth stepper motor 609, so that the lifting frame 610 slides up and down along the outer surface of the sixth guide rod 608; and the welding angle of the second laser welding head 611 can be changed by the output end of the eighth drive motor 612.

[0034] Working principle and use process of this device: In order to clearly describe the working principle of the present invention, we use Figure 1 The perspective is explained as follows: S1. The first mechanical arm 101 transfers one end of the external pipe 102 to the inside of the rotating disk 202, and drives the second gear 210 to rotate through the output end of the second driving motor 213, so that the outer gear 208, the rotating circle 206 and the inner gear 207 rotate as a whole, and then all the first gears 209 rotate synchronously, so that all the first clamping members 211 move synchronously toward the position close to the center of the rotating disk 202, so as to clamp the pipe 102; S2, the output end of the first electric push rod 306 is extended, driving the laser cutting head 307 to move downward close to the pipe 102, and the transmission gear 205 is driven to rotate through the output end of the first drive motor 204, so that the fixed gear 203 and the turntable 202 rotate synchronously as a whole, driving the clamped pipe 102 to rotate. At the same time, under the action of the output end of the first stepper motor 304, the first movable plate 305 slides back and forth along the first guide rod 303, thereby driving the laser cutting head 307 to move back and forth. By controlling the output end speed of the first drive motor 204 and the first stepper motor 304, the saddle mouth can be opened; S3, under the action of the output end of the second stepper motor 404, the two groups of second clamping members 415 extend into the interior of the pipe 102, and the first screw 412 is driven to rotate by the output end of the first servo motor 414, so that the two groups of second clamping members 415 move away from each other and clamp the inner wall of the pipe 102, and the first drive motor 204 and the fifth drive motor 410 are started synchronously, and the rotation speed and direction of the two are consistent, and the pipe 102 is driven to rotate together, and the laser cutting head 307 is started at the same time, so as to cut off a section of the pipe with the saddle mouth, that is, the first pipe section 103. It is worth noting that since the two groups of second clamping members 415 clamp the inner wall of the first pipe section 103, the first pipe section 103 will not fall to the ground; S4, under the action of the output end of the second stepper motor 404, the two groups of second clamping members 415 and the clamped first pipe section 103 move to the second splicing mechanism 5, and the output end of the third drive motor 406 rotates to drive the clamped first pipe section 103 to rotate toward the second splicing mechanism 5, and then under the action of the output end of the third stepper motor 504, the two groups of third clamping members 519 extend into the interior of the first pipe section 103, and then the output end of the second servo motor 518 drives the second screw 516 to rotate, so that the two groups of third clamping members 519 move away from each other, so as to clamp the inner wall of the first pipe section 103 (the clamping state is as shown in FIG. 4). Figure 8 shown); S5, the first robot arm 101 clamps the pipe 102, and all the first clamping members 211 release the clamping of the pipe 102, and the first robot arm 101 pushes the pipe 102 to the front side, and then all the first clamping members 211 clamp the pipe 102 again, and the clamped pipe 102 is driven to rotate forward and reversely through the output end of the first drive motor 204, and the laser cutting head 307 is synchronously moved back and forth, so as to realize the opening of the splicing groove corresponding to the saddle mouth; S6. Afterwards, under the action of the output end of the second stepper motor 404, the two groups of second clamping members 415 are extended into the interior of the pipe 102 again, and the two groups of second clamping members 415 are moved away from each other to clamp the inner wall of the pipe 102. The first drive motor 204 and the fifth drive motor 410 are started synchronously, and the rotation speed and direction of the two are consistent, driving the pipe 102 to rotate together, and the laser cutting head 307 is started at the same time, so as to cut off a section of pipe with a splicing groove, that is, the second pipe section 104. Under the action of the output end of the second stepper motor 404, the two groups of second clamping members 415 and the clamped second pipe section 104 are moved to the second splicing mechanism 5, and the two groups of second clamping members 415 are driven to maintain a vertical state through the output end of the fourth drive motor 409, and then the clamped second pipe section 104 is driven to rotate through the output end of the fifth drive motor 410, so that the splicing groove faces the second splicing mechanism 5; S7, changing the positions of the two sets of third clamping members 519 in the horizontal, vertical and vertical directions, and with the cooperation of the output end of the sixth drive motor 514, aligning the saddle mouth on the first pipe segment 103 with the splicing groove on the second pipe segment 104, and finally, with the action of the output end of the third stepper motor 504, splicing the saddle mouth on the first pipe segment 103 and the splicing groove on the second pipe segment 104 together, and driving the first laser welding head 521 to approach the splicing position for welding through the extension of the output end of the second electric push rod 520, so as to achieve preliminary welding; S8, the second robot arm 105 transfers the first pipe segment 103 and the second pipe segment 104 after preliminary welding to between the two sets of fourth clamping members, and drives the third screw rod 603 to rotate through the output end of the third servo motor 605, so that the two sets of fourth clamping members approach each other, clamping the two ends of the second pipe segment 104, and the first pipe segment 103 remains vertical; S9, the frame 602 is driven to rotate by the output end of the seventh driving motor 601, so that the second pipe segment 104 and the first pipe segment 103 rotate as a whole, and the second laser welding head 611 moves up and down and the angle of the second laser welding head 611 changes synchronously, so as to achieve full welding at the joint of the second pipe segment 104 and the first pipe segment 103; S10. After the comprehensive welding is completed, the pipe is transferred to an external conveying machine through the second robot arm 105 again, and the above operation is repeated to complete the automated production of the equal-diameter tee pipe. No staff operation is required, which saves labor costs, improves the production efficiency of the equal-diameter tee pipe, and meets the needs of the staff.
