[0002] Copper tubes are one of the important components of air conditioners. There are a large number of copper tubes of different specifications in the condenser and evaporator. Therefore, in the process of air conditioning manufacturing, the welding of copper tubes is an indispensable process. Welding machines are mostly used to complete the welding of copper tubes. Welding tooling is one of the main structures of the welding machine. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a welding support tool for an air-conditioning copper pipe with publication number: CN210147372U, comprising a magnetic adsorption base, a supporting shaft, a mounting shell, a first clamping block, a second clamping block, a sliding rod, an L-shaped slide plate, a sliding groove, a limiting block, a second screw, an arc-shaped anti-skid pad, a first screw, a connecting rod, a rolling ball, an arc-shaped pressure block, a sliding block and a stop block. By rotating the second screw, the second screw drives the second clamping block connected to its thread to move downward on the side wall of the L-shaped slide plate through the sliding rod and the sliding groove, so that the second clamping block presses against the first clamping block to clamp the copper pipe. If the angle of the copper pipe needs to be adjusted, the first screw can be rotated to make the first screw drive the arc-shaped pressure block to release the rolling ball. At this time, the connecting rod connected to the rolling ball is rotated to adjust the angle of the first clamping block, so that the angle of the copper pipe can be adjusted. After the end, the first screw is rotated to make the arc-shaped pressure block press against the rolling ball to fix the angle of the copper pipe, thereby improving the adaptability of the device and the stability of the copper pipe support and fixation.

[0004] In the above utility model, the first clamping block can rotate with the ball as the center through the connecting rod. Rotating the first screw can make the arc-shaped pressure block press the ball. At this time, the use position of the first clamping block is fixed. During the welding process, the welding gun contacts the copper tube, which may easily cause the copper tube to drive the connecting rod and the ball to rotate accidentally through the first clamping block. There is no prompt structure, and the operator cannot know whether the copper tube is accidentally offset, which reduces the practicality of the use of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model provides an air conditioner copper tube welding tool and welding machine, which have the following beneficial effects:

[0020] (1) The utility model adopts a socket hole plate. When the air-conditioning copper tube welding tooling and welding machine are actually used, the operator first rotates the ball rod by hand with the ball socket as the center of the circle, and the ball rod can drive the socket hole plate and the first clamping plate to rotate. When the first clamping plate is rotated to a suitable position, the threaded through hole cooperates with the adjusting bolt thread, and the operator rotates the adjusting bolt by hand.

Then, the thread lever cooperates with the thread of the screw sleeve, and the operator rotates the hand wheel by hand. The hand wheel pushes the screw sleeve through the thread lever, and the screw sleeve drives the first clamping plate through the moving plate. When the copper tube is moved, when it is clamped and fixed by the first clamping plate and the second clamping plate, an external welding gun can be used to weld the copper tube. When the copper tube is accidentally deviated, the socket hole plate will pull the two sets of pull ropes, and the two sets of pull ropes will drive the two sets of extension plates to move through the two sets of socket blocks. When the two sets of extension plates respectively press the two sets of push switches, the two sets of buzzer alarms start to work. The operating worker can be reminded by the sound of the two sets of buzzer alarms whether the copper tube is deviated. During this process, the two sets of socket blocks and the two sets of L-shaped plates will squeeze the four sets of telescopic springs, and the four sets of T-shaped cross bars ensure the stability of the lateral movement of the two sets of socket blocks. The limit slots and the I-shaped slider ensure the stability of the movement of the second clamping plate. The socket hole plate is set with a prompt structure, which can remind the operating worker whether the copper tube is accidentally deviated, ensure that the operating worker is informed in time and removes the welding gun, thereby improving the practicality of the air-conditioning copper tube welding tooling and welding machine.

[0021] (2) The utility model adopts a first airbag and a second airbag. Before actually using the air-conditioning copper tube welding tool and the welding machine, the operator first moves the base by hand. When the base is moved to a suitable position, since the welding table is made of iron material, the four groups of magnet columns can adsorb the welding table. At this time, the electric telescopic rod can be used stably. When the base needs to be removed, the operator steps on the second airbag by hand.

[0040] Working principle:

[0041] When the welding tool and welding machine for the air-conditioning copper tube are actually used, the operator first rotates the ball rod 7 with the ball socket 6 as the center by hand, and the ball rod 7 can drive the socket hole plate 12 and the first clamping plate 13 to rotate. When the first clamping plate 13 is rotated to a suitable position, the threaded through hole 9 cooperates with the thread of the adjusting bolt 10, and the operator rotates the adjusting bolt 10 by hand. When the arc plate 11 contacts the spherical end of the ball rod 7, the use position of the ball rod 7 and the first clamping plate 13 is fixed, and then the socket hole plate 12 is moved along the ball rod 7. The socket hole plate 12 will pull the two sets of draw ropes 24. When the socket hole plate 12 moves to a suitable position, the operator rotates the two sets of fastening bolts 27 clockwise by hand. When the two sets of fastening bolts 27 are in close contact with the two sets of draw ropes 24 respectively, the copper tube is moved. To between the first clamping plate 13 and the second clamping plate 20, and then use the threaded lever 17 and the screw sleeve 18 to cooperate with each other, the operator rotates the handwheel 21 by hand, the handwheel 21 pushes the screw sleeve 18 through the threaded lever 17, and the screw sleeve 18 drives the first clamping plate 13 to move through the movable plate 19. When the copper tube is clamped and fixed by the first clamping plate 13 and the second clamping plate 20, an external welding gun can be used to weld the copper tube. When the copper tube is accidentally offset, the socket hole plate 12 will pull the two sets of pull ropes 24, and the two sets of pull ropes 24 drive the two sets of extension plates 28 to move through the two sets of socket blocks 26. When the two sets of extension plates 28 press the two sets of push switches 31 respectively, the two sets of buzzer alarms 30 start to work, and the operator can use the two sets of buzzer alarms 30 to The sound emitted reminds the operator whether the copper tube is offset.
