[0002] Existing pipe welding equipment mostly uses a clamping assembly to clamp one end of the pipe, and then uses welding equipment to weld the fixed pipe. However, during the clamping process, the clamping force should be impartial.

If the clamping force is heavy, some thin pipes will be deformed due to the strong clamping force. This places high requirements on the workers who operate the clamping assembly and requires them to be very experienced. Therefore, this structure is not practical enough and needs to be improved.

[0026] Example

[0027] The present embodiment provides a pipe welding device, including an integrated stand 1, on which a welding robot 2 and a welding station 3 located outside the welding robot 2 are arranged. The number of welding stations 3 can also be set according to demand, preferably a double station located on both sides of the welding robot 2; each welding station 3 is provided with a welding table 4 and a fixture bracket 5, and two movable plates 6 are arranged on the welding table 4, and a movable guide rail system 7 is provided between the movable plate 6 and the welding table 4 to drive the movable plates 6 to move away from or approach each other at the same time;

[0028] A left clamp 8 and a right clamp 9 are respectively arranged on the two movable plates 6. The left clamp 8 and the right clamp 9 have the same structure and are centrally symmetrically arranged. The movable guide rail system 7 makes the left clamp 8 and the right clamp 9 approach and move away from each other to achieve the clamping and loosening effects. The left clamp 8 or the right clamp 9 includes a blade limit block 10. A clamping cylinder 11 is arranged at one end of the blade limit block 10. A clamping piece 12 is arranged at the output end of the clamping cylinder 11. A blade clamp 13 that can be clamped on the blade limit block 10 by the clamping piece 12 is arranged on the blade limit block 10. In the future, When in use, the blade clamp 13 can be replaced according to the needs of use. It can clamp the hanger and also has the function of protecting the sparks generated by the welding process. The opposite ends of the blade clamps 13 of the left clamp 8 and the right clamp 9 are provided with arc-shaped recesses 16 for accommodating pipe fittings, and the upper end of the clamp bracket 5 is provided with a support component 17 inserted into the pipe fitting to support the pipe fitting. The support component 17 prevents the pipe fitting from being clamped and flattened, and at the same time provides a stable supporting force for welding. Part of the support component 17 is located in the arc-shaped recess 16, and the center line of the support component 17 coincides with the axis line of the arc-shaped recess 16.

[0029] The movable guide rail system 7 includes a guide rail 18 provided on the welding table 4, two sliders 19 sliding on the guide rail 18, and the movable plates 6 are respectively connected to the adjacent sliders 19. The opposite ends of the movable plates 6 are hinged with push-pull cylinders 20. The other ends of the push-pull cylinders 20 are hinged to the welding table 4 and close to the position of another movable plate 6. The telescopic movement of the push-pull cylinders 20 drives the movable plates 6 to move away from or closer to each other, and drives the left clamp 8 and the right clamp 9 to clamp or release the pipe fittings.

[0030] The end of the blade clamp 13 that is away from the blade clamp 13 is connected to a fixing plate 21 , and the fixing plate 21 is fixed to the outer side of the blade limiting block 10 by fastening bolts, so as to further stably fix the blade clamp 13 on the blade limiting block 10 .

[0031] The support assembly 17 includes a fixed plate 15 installed on the upper end of the clamp bracket 5, and a rotating mechanism 22 is provided on the fixed plate 15. A pneumatic finger 23 extending into the pipe fitting is provided at the output end of the rotating mechanism 22. The pipe fitting is inserted into the pneumatic finger 23, and the pneumatic finger 23 opens to support the pipe fitting. When encountering a pipe fitting with an outer circle and an inner defense, the rotating mechanism 22 is required to rotate the pneumatic finger 22 to adapt to the pipe fitting, which is practical and flexible.

[0032] It also includes a wire device 25 for providing power to the rotating mechanism 22 and the pneumatic finger 22. The wire device 25 is installed on the end of the fixed disk 15 away from the pneumatic finger 22. The wire device 25 effectively solves the problem of wire entanglement when the equipment rotates, ensuring that the current can be accurately transmitted to the rotating parts to avoid damage during operation.

[0033] It also includes a fully automatic gun cleaner 24 for cleaning impurities in the welding gun, which is arranged between the two welding stations 3.

[0034] It also includes a pneumatic triplex 25 provided between the two welding stations 3, which is used to purify and filter the air source entering the pneumatic instrument and reduce the pressure to the rated air source pressure supplied by the instrument.

[0035] The blade limit blocks 10 are respectively inclined toward the two ends of the pipe, and the arc-shaped notches 16 thereof form a circular hole to accommodate the pipe. The blade limit blocks 10 clamp the pipe from front to back, and the clamping is stable while having high protection.

[0036] When the utility model product is implemented:

[0037] Install the components that support the pipe fittings on the welding station, and make one end of the pipe fittings located in the arc-shaped notch while the pneumatic fingers are located in the pipe fittings. Then drive the push-pull cylinder, and the electric blade clamps move close to each other to clamp the pipe fittings. At the same time, drive the pneumatic fingers, and the pneumatic fingers open to support the pipe fittings. Then you can start the welding robot to perform the welding process.

[0038] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
