For this reason, we propose a stainless steel pipe welding device. Utility Model Content

[0023] In the above structure, by setting the adjusting disk 2, the fixing plate 5, and the slider 20 structure, the fixing plate 5 is used to fix the stainless steel pipe. The user can use the fixing block 12 and the welding gun to perform welding operations on the joints of the stainless steel pipe. After welding part of the weld, the user can drive the driving wheel 6 to rotate through the motor 13, so that the turntable drives the adjusting disk 2 to rotate, thereby adjusting the unwelded part of the pipe to correspond to the welding gun, which is convenient for the user to adjust the angle of the pipe to continue the welding operation without the need for manual adjustment by the user, thereby improving the user's welding efficiency of the stainless steel pipe.

[0024] In a preferred embodiment: a turntable is fixedly mounted on the outer wall of the driving wheel 6, and the shape and diameter of the turntable are compatible with the shape and diameter of the movable groove 14, the outer wall of the adjusting disk 2 is fixedly mounted on the outer wall of the turntable, and the inner wall of the slide groove 3 is slidably connected to the outer wall of the slider 20.

[0025] In the above structure, through the turntable and movable groove 14 structure, the turntable can drive the adjustment disk 2 to rotate synchronously, so as to achieve the effect of automatic adjustment of the pipeline angle, and the slide groove 3 can provide a movable space for the movement of the slider 20, so that the fixed plate 5 is displaced due to the movement of the slider 20, thereby achieving the effect of adjusting the distance between the two fixed plates 5, and then making the device suitable for welding operations of stainless steel pipelines of different lengths, thereby improving the scope of use of the device.

[0026] In a preferred embodiment: a through hole is opened on the inner wall of the mounting groove 15, and the inner wall of the through hole is rotatably connected to the outer wall of the transmission rod 17, the inner wall of the long groove 16 is slidably connected to the outer wall of the fixed block 12, the number of driven wheels 8 is two, and the two driven wheels 8 are transmission connected through the transmission rod 17.

[0028] In a preferred embodiment: a welding gun is fixedly mounted on the top of the fixed block 12, and the fixed block 12, the sliding block 20, and the rotating rod 4 are all made of galvanized iron metal.

[0030] In a preferred embodiment, the number of the fixing bolts 9 is two, and the distance between the two fixing bolts 9 is adjusted by moving the slide block 20 .

[0031] In the above structure, by setting two fixing bolts 9, after adjusting the distance between the two fixing plates 5, the user can adjust the distance between the two clamping plates by rotating the fixing bolts 9, so that the pipeline can be fixed. After the pipeline is fixed, the user can use the mobility of the fixing plate 5 again to dock the two pipelines, thereby ensuring the stability of the pipeline during the welding process.

[0032] In a preferred embodiment: the number of fixing plates 5 is two, and the two fixing plates 5 are symmetrically distributed along the outer wall of the bracket 1, threaded holes are opened on the outer walls on both sides of the fixing plates 5, and the inner walls of the threaded holes are threadedly connected to the outer walls of the fixing bolts 9, and the end of the fixing bolts 9 is rotatably connected to a clamping plate.

[0033] In the above structure, by setting up two fixing plates 5, after the device fixes the pipeline, the user can drive the double-threaded rod 19 to rotate through the motor 18, so that the two sliders 20 move towards or oppositely, so that the distance between the two fixing plates 5 is reduced or increased, and the user does not need to manually adjust the position of the fixing plates 5, thereby improving the automation of the device.

[0034] Working principle: first, the user drives the double-threaded rod 19 to rotate through the output shaft of motor 18 to adjust the spacing between the two fixed plates 5, then places a pipe on a fixed plate 5, and fixes the pipe by rotating the fixing bolt 9. Then, after fixing the other pipe through the same steps above, the user can again rotate the output shaft of motor 18 to make the ends of the two pipes fit tightly together, and then drive the screw 11 to rotate through the output shaft of motor 21 to adjust the position of the welding gun to the position corresponding to the pipe connection, and then perform welding operations through the welding gun. After welding a part, the user can stop the welding gun, and then drive the driving wheel 6 to rotate through the output shaft of motor 13, so that one adjustment disk 2 rotates, and the other adjustment disk 2 rotates synchronously under the transmission cooperation of the transmission belt 7, the driven wheel 8 and the transmission rod 17, so that the two pipes rotate synchronously to ensure that the weld will not break, and there is no need for the user to manually adjust the pipe angle, thereby improving the user's welding efficiency of the pipe.
