[0028] Figure 1 The utility model shows a rotary positioning tool for welding an air-conditioning liquid dispensing pipe, comprising an L-shaped support plate 1, a through hole Ⅰ being provided at the center of one side plate of the support plate 1, and further comprising: a rotating plate 2, the rotating plate 2 being rotatably connected to the support plate 1 via a rotating shaft 3 passing through the through hole Ⅰ, a positioning clamping device for fixing the air-conditioning liquid dispensing pipe 13 being provided on the upper surface of the rotating plate 2, and four arc grooves 4 being evenly provided around the through hole Ⅰ on the lower surface of the rotating plate 2;

[0029] The support plate 1 is provided with a fixing piece, and the fixing piece extends into the arc groove 4 to limit the position of the welding point of the air-conditioning liquid distribution pipe 13 after rotating to a predetermined angle.

[0030] Working principle:

[0031] First, place the air-conditioning liquid dispensing tube 13 to be welded on the rotating plate 2 and fix it by the positioning clamping device. According to the position of the welding spot to be welded, rotate the rotating plate 2 manually or mechanically to make the air-conditioning liquid dispensing tube 13 reach the predetermined welding angle. When the air-conditioning liquid dispensing tube 13 rotates to the predetermined welding angle, use the fixing piece on the support plate 1 to extend into the corresponding arc groove 4, thereby limiting the further rotation of the rotating plate 2 to ensure the accuracy and stability of the welding point position. After the welding point position is fixed, the welding operation can be carried out. During the welding process, due to the fixing effect of the rotating plate 2 and the positioning clamping device, the air-conditioning liquid dispensing tube 13 will maintain a stable posture to ensure the welding quality. Through the rotation of the rotating plate 2, the air-conditioning liquid dispensing tube 13 can be easily adjusted to any required welding angle to achieve a full range of welding operations. The dual fixing effect of the positioning clamping device and the fixing piece keeps the air-conditioning liquid dispensing tube 13 stable during the welding process to avoid movement or shaking.

[0032] In the above scheme, the positioning and clamping device includes: a positioning module for fixing the branch pipe and the upper main pipe of the air-conditioning liquid distribution pipe and a clamping module for fixing the middle main pipe of the air-conditioning liquid distribution pipe 13. With this technical method, the positioning module and the clamping module can realize the rapid positioning and clamping of the air-conditioning liquid distribution pipe, ensuring that the liquid distribution pipe will not move or deform during the welding process, thereby improving work efficiency.

[0033] In the above scheme, the positioning module includes: a plurality of positioning blocks Ⅰ5 arranged on the rotating plate 2, which abut against the multiple branches at the lower end of the air-conditioning liquid distribution pipe 13; a support block 6 abutting against the main pipe at the upper end of the air-conditioning liquid distribution pipe; wherein, the positioning block Ⅰ5 is provided with a positioning hole 11 for the branch pipes of the air-conditioning liquid distribution pipe 13 to extend into, and the support block 6 is provided with an arc groove consistent with the shape of the air-conditioning liquid distribution pipe 13. Using this technical method, the positioning blocks Ⅰ5 are arranged on the rotating plate 2, and the number matches the number of branches at the lower end of the air-conditioning liquid distribution pipe 13. Each positioning block Ⅰ5 is provided with a positioning hole 11, and the size of the positioning hole 11 is consistent with the branch pipe to ensure that the branch pipe of the air-conditioning liquid distribution pipe 13 can be accurately extended into and fixed in the hole. In this way, the branch pipe part of the liquid distribution pipe is stably fixed to prevent its movement or dislocation during installation or maintenance. The arc groove formed on the support block 6 is completely consistent with the outer shape of the upper main pipe of the air-conditioning liquid dispensing pipe 13, and the upper main pipe part can fit perfectly in the groove, further enhancing the overall stability.

[0034] In the above scheme, the clamping module includes: a positioning block II7 arranged on the rotating plate 2 and abutting against the middle main pipe of the air-conditioning liquid dispensing pipe 13; a quick positioning clamp 9 arranged on the rotating plate 2 through a connecting block 8, and a clamping block 10 is arranged at the movable end of the quick positioning clamp 9; wherein, an arc groove consistent with the shape of the air-conditioning liquid dispensing pipe 13 is opened on the positioning block II7 and the clamping block 10, and the lower surface of the clamping block 10 can abut against and separate from the upper surface of the positioning block II7 through the reciprocating motion of the quick positioning clamp 9, and the arc grooves of the clamping block 10 and the positioning block II7 are in contact with the side wall of the middle main pipe of the liquid dispensing pipe. With this technical method, because the positioning block II7 and the clamping block 10 are provided with an arc groove consistent with the shape of the air-conditioning liquid dispensing pipe 13, the middle main pipe of the air-conditioning liquid dispensing pipe 13 can be placed in the positioning block II7, and through the reciprocating motion of the quick positioning clamp 9, the lower surface of the clamping block 10 can abut against and separate from the upper surface of the positioning block II7. When the dispensing tube needs to be clamped, the movable end of the quick positioning clamp 9 moves toward the positioning block Ⅱ7, so that the clamping block 10 fits tightly with the positioning block Ⅱ7, thereby clamping the dispensing tube; when the dispensing tube needs to be loosened, the movable end of the quick positioning clamp 9 moves in the opposite direction, so that the clamping block 10 separates from the positioning block Ⅱ7, thereby releasing the dispensing tube.

[0035] In the above scheme, a through hole II is provided on the support plate 1, and the through hole II is located outside the through hole I, and a spring locating pin 12 is inserted into the through hole II; wherein, the lower end of the spring locating pin 12 extends into the arc groove 4. With this technical method, on the support plate 1, the through hole I is located on the same side plate as the through hole I, but is located outside the through hole I. The through hole II is designed to penetrate the spring locating pin 12. It is penetrated in the through hole II, and its lower end can extend into the arc groove 4 around the through hole I on the lower surface of the rotating plate 2. The spring locating pin 12 contains a spring mechanism inside, so that it can be extended and retracted under the action of external force. When the rotating plate 2 rotates to a predetermined angle, the operator can extend the lower end of the spring locating pin 12 into the corresponding arc groove 4 to achieve the preliminary positioning of the rotating plate 2. The spring mechanism of the spring locating pin 12 ensures that even in the absence of external force, its lower end will remain in the arc groove 4, thereby fixing the position of the rotating plate 2 and preventing it from moving unnecessarily during welding. When the rotating plate 2 needs to be rotated again, the operator only needs to use a little force to pull the spring positioning pin 12 out of the arc groove 4 to release the fixation, which is convenient for the next rotation and positioning.

[0036] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
