[0027] As Figures 1 to 6 shown, the present invention provides a metal pipe welding device, including:

[0028] Base 1, long grooves 2 are respectively opened on the front and rear sides of the top of the base 1, and a metal pipe 3 is movably connected to the top of the base 1;

[0030] Clamping mechanism, the clamping mechanism is arranged on the top of the base 1;

[0031] Among them, the clamping mechanism includes two first pneumatic cylinders 7. The bottoms of the two first pneumatic cylinders 7 are respectively fixedly installed on the outer surfaces of the bottoms of the front and back of the base 1. The other end of the first pneumatic cylinder 7 is fixedly installed at the bottom of the baffle 24. The top of the first pneumatic cylinder 7 penetrates through the bottom of the baffle 24 and extends above the baffle 24. A lifting block 8 is fixedly installed at the top of the first pneumatic cylinder 7. Movement shafts 9 are hinged on the left and right sides of the top of the lifting block 8. The other end outer surface of the movement shaft 9 is hinged with a movement block 10. A movement column 11 is fixedly installed at the top of the movement block 10. The top of the movement column 11 extends above the base 1 through the long groove 2. A clamping block 25 is fixedly installed on the right side of the movement column 11. The bottom end of the clamping block 25 is movably connected to the top of the base 1. When the lifting block 8 moves downward, the movement shafts 9 and the movement blocks 10 drive the two clamping blocks 25 to move towards each other to clamp and fix the metal pipe 3.

[0032] When the first pneumatic cylinder 7 operates, the lifting block 8 will drive the four moving shafts 9 to move at this time. At this time, the other ends of the four moving shafts 9 will pull the four moving blocks 10 to move towards each other. Subsequently, the four moving blocks 10 will drive the four clamping blocks 25 to move towards each other at the top of the base 1 through the moving columns 11. At this time, the metal pipe 3 located between the four clamping blocks 25 will be clamped and fixed during the mutual movement of the four clamping blocks 25.

[0033] Among them, fixing plates 4 are fixedly installed on the right sides of the tops of the front and back of the base 1. The number of fixing plates 4 is two. A long plate 5 is fixedly installed on the left sides of the two fixing plates 4. A limiting groove 6 is opened inside the long plate 5.

[0034] Due to the design of the limiting groove 6, the object passing through the inside of the long plate 5 will be limited, so that it can only move left and right.

[0035] Among them, a fixing block 12 is fixedly installed on the top of the right side of the base 1. A double-shaft motor 13 is fixedly installed inside the fixing block 12. The other ends of the output shafts of the double-shaft motor 13 are fixedly sleeved with threaded rotating shafts 14. The other ends of the threaded rotating shafts 14 penetrate through the inner surface of the fixing block 12 and extend to the outside of the fixing block 12. The number of threaded rotating shafts 14 is two. The other ends of the two threaded rotating shafts 14 are movably sleeved with the inside of the fixing plate 4.

[0036] When the double-shaft motor 13 operates, the threaded rotating shafts 14 will rotate at this time.

[0037] Among them, moving rods 15 located between the fixing block 12 and the fixing plate 4 are threadedly sleeved on the outer surfaces of the two threaded rotating shafts 14. The other ends of the moving rods 15 extend above the two moving columns 11 through the limiting groove 6. A push rod 16 is fixedly installed on the left side of the bottom end of the moving rod 15. The push rod 16 is located between the two moving columns 11.

[0038] Threads are provided on the outer surfaces of the two threaded rotating shafts 14 located between the fixing block 12 and the fixing plate 4. When the threaded rotating shafts 14 rotate, due to the limiting effect of the limiting groove 6, the two moving rods 15 will move towards each other along the outer surfaces of the threaded rotating shafts 14. At this time, the push rod 16 will move towards each other under the drive of the moving rod 15, so as to achieve the effect of pushing the opposite ends of the two metal pipes 3 to align.

[0039] Among them, a moving motor 17 is fixedly installed on the outer surface of the left side of the base 1. The other end of the output shaft of the moving motor 17 is fixedly sleeved with a rotating shaft 18. The other end of the rotating shaft 18 penetrates through the outer surface of the left side of the base 1 and extends to the back. The other end of the rotating shaft 18 is fixedly sleeved with a gear 19.

[0040] When the moving motor 17 operates, the rotating shaft 18 will drive the gear 19 to rotate at this time.

[0041] Among them, the outer surface of the gear 19 is meshed and connected with a toothed ring 20. The bottom end of the toothed ring 20 is fixedly installed with a circular ring 21. The front and rear ends of the circular ring 21 are movably sleeved inside the base 1.

[0042] When the gear 19 rotates, at this time the gear 19 will drive the circular ring 21 to rotate through the toothed ring 20.

[0043] Among them, a second pneumatic cylinder 22 is fixedly installed on the outer surface of the circular ring 21. The other end of the second pneumatic cylinder 22 penetrates the outer surface of the circular ring 21 and extends into the interior of the circular ring 21. The other end of the second pneumatic cylinder 22 is fixedly installed with a welding head 23.

[0044] Due to the design of the second pneumatic cylinder 22, the welding head 23 can move up and down to complete the welding work on metal pipes 3 of different sizes.

[0045] The working principle and usage process of the present utility model:

[0046] First of all, the operator places two metal pipes 3 between the four clamping blocks 25. Then the double-shaft motor 13 is started. When the double-shaft motor 13 operates, at this time the threaded rotating shaft 14 will rotate. Due to the limiting effect of the limiting groove 6, at this time the two moving rods 15 will move towards each other along the outer surface of the threaded rotating shaft 14. At this time, the push rod 16 will drive the two metal pipes 3 to move towards each other under the drive of the moving rod 15, and finally the joints at the opposite ends of the two metal pipes 3 are in contact, thus realizing the effect of automatically aligning the two metal pipes 3.

[0047] Subsequently, the operator starts the first pneumatic cylinder 7. At this time, the top end of the first pneumatic cylinder 7 will drive the lifting block 8 to move downward. When the lifting block 8 moves downward, it will cause the moving shaft 9 to move. At this time, the four moving blocks 10 will move towards each other under the drive of the four moving shafts 9. Subsequently, the four moving blocks 10 will drive the four clamping blocks 25 to move towards each other through the four moving columns 11. Finally, the two metal pipes 3 will be clamped and fixed in the mutual movement of the four clamping blocks 25, thus realizing the effect of automatically clamping and fixing metal pipes 3 of different sizes.

[0048] After that, the operator starts the second pneumatic cylinder 22. When the second pneumatic cylinder 22 operates, it will cause the welding head 23 to move downward. When the bottom end of the welding head 23 touches the joint of the two metal pipes 3, stop operating the second pneumatic cylinder 22. Then start the movement motor 17. At this time, the rotating shaft 18 will drive the gear 19 to rotate. When the gear 19 rotates, it will drive the entire circular ring 21 to rotate through the toothed ring 20, thus realizing the function of automatically welding the metal pipe 3 in a circular shape.
