A control panel 63 and a PLC controller 64 are fixedly connected to one side of the outer wall of the front end of the welding box 38.

[0035] By electrically connecting the control panel 63, the first servo motor 5, the second servo motor 25, the third servo motor 40, the first electric telescopic rod 31, the second electric telescopic rod 47, the first infrared sensor 57, the second infrared sensor 58 and the high-pressure air pump 50 to the PLC controller 64, it is convenient for staff to operate it.

[0036] A driving pinion 10 is fixedly connected to the outer wall of the upper end of the first bidirectional threaded rod 6 , and a driven pinion 11 is fixedly connected to the outer wall of the upper end of the second bidirectional threaded rod 7 . A rack 12 is sleeved on the outer walls of the driving pinion 10 and the driven pinion 11 .

[0037] Working principle: The welding equipment first starts the first servo motor 5 according to the diameter of the steel pipe to be welded, which can make the first bidirectional threaded rod 6 rotate. At this time, under the action of the active pinion 10, the driven pinion 11 and the rack 12, the second bidirectional threaded rod 7 starts to rotate synchronously, and the transverse threaded plate 8 starts to move towards each other and drives the positioning arc plate 22 to move. At the same time, during the movement of the transverse threaded plate 8, the adjustment block 18 will be driven to move toward the inside of the second rectangular through hole 19. At this time, the adjustment baffle 21 will start to move toward the outside of the adjustment box 17 under the action of the adjustment spring 20. At this time, the positioning arc plate 22 starts to tilt slightly toward the center of the transmission box 2 under the action of the adjustment baffle 21. After the position adjustment of the positioning arc plate 22 is completed, Then put the steel pipe to be welded into the transmission box 2. At this time, the steel pipe will slide on the outer wall of the rotating bead 23. Since the positioning arc plate 22 is at an inclined angle at this time, the number of the rotating bead 23 and the outer wall of the steel pipe will increase, which makes it easier for the staff to place and position the steel pipe. At the same time, the steel pipe will pass through the limit frame 34 and move to the inside of the welding box 38 during the slow movement inside the transmission box 2. The first infrared sensor 57 and the second infrared sensor 58 are in the open state. When the steel pipe moves to the lower end of the first infrared sensor 57, the first infrared sensor 57 will send a signal command to the first electric telescopic rod 31, causing it to start working and clamp the outer wall of the steel pipe through the arc clamping plate 32, and then the second servo motor 25 will make the one-way The threaded rod 26 rotates, thereby causing the vertical threaded plate 27 and the fixed plate 28 to drive the clamping ring 29 and the steel pipe to move toward the direction of the second infrared sensor 58. When it moves to the bottom of the second infrared sensor 58, the second infrared sensor 58 will send a signal command to the second servo motor 25 to stop it. At this time, the welding position of the single steel pipe has been accurately determined, and then the steel pipe is placed in the other end of the transmission box 2 and the above steps are repeated. At this time, the two steel pipes to be welded are accurately positioned inside the welding box 38, and the welding positions are reserved for the two steel pipes to be welded. Then, the second servo motor 25 is manually started to make the steel pipes move slowly and synchronously toward each other and move to the inside of the rotating ring 43, and then the third servo motor 40 is started to The active large gear 41 drives the teeth 44 and the rotating ring 43 to rotate, and the rotating ring 43 drives the cleaning ring 45 and the cleaning pad 46 to rotate, so that the cleaning pad 46 can clean the steel pipe to be welded during the rotation process, effectively reducing the influence of dust and impurities on the welding effect of the steel pipe welding. At the same time, according to the diameter of the steel pipe, the second electric telescopic rod 47 is started to move the welding gun 48 to the welding position. At the same time, under the action of the second servo motor 25, the two steel pipes are moved to the welding position. At this time, the welding gun 48 starts to rotate in a circle and starts welding the outer wall of the steel pipe. At the same time, starting the high-pressure air pump 50 can make the dust suction head 55 start to do dust suction work, and the dust enters the interior of the filter box 49 through the dust suction pipe 56.The adsorbed gas is then filtered through the large-pore filter plate 51, the medium-pore filter plate 52 and the fine-pore filter plate 53, thereby improving the environmental performance of the device. After the steel pipe is welded and cooled, the first electric telescopic rod 31 and the second servo motor 25 on one side are turned off and the first electric telescopic rod 31 and the second servo motor 25 on the other side are started, so that the welded steel pipe can be moved to the inside of the transmission box 2 on one side. After moving to the initial position, the second servo motor 25 stops working, and the first electric telescopic rod 31 returns to its original position. At this time, the staff can pull out the steel pipe from the inside of the transmission box 2.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
