[0002] The condenser is a component of the refrigeration system and a type of heat exchanger. It can convert gas or steam into liquid and transfer the heat in the tube to the air near the tube in a very fast way. The condenser copper tube is composed of various components, among which the condenser copper tube is an important component of the condenser. Most of the condenser copper tubes are round. In order to transmit the medium, other branches need to be welded on the bent round copper tube to facilitate the transmission of the condensing medium between the copper tubes.

[0003] However, there is no special welding mold to assist in welding the existing condenser branch pipe and the condenser round copper pipe. Welding mainly relies on manual hand-held welding. The placement angle of the branch pipe is not accurate during welding. If it is not placed vertically, it will be greatly deformed after welding. The subsequent reshaping is time-consuming and laborious. In addition, manual welding is not stable enough and is prone to shaking, which can easily affect the welding quality. Utility Model Content

[0004] The purpose of the present application is to provide a welding mold for condenser copper tubes to solve the problems raised in the above background technology.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] 1. In the utility model, when working, the copper pipe to be welded is fixed by the supporting assembly. After the fixing is completed, the vertical pipe to be welded is inserted into the fixing tube for fixing. Then the electric telescopic rod drives the fixing tube to descend and then the vertical pipe plugged therein is descended to make it contact with the copper pipe to be welded. The vertical pipe is pressed by the fixing tube so that the vertical pipe and the copper pipe fit closely, which is convenient for welding. Compared with the traditional manual fixing method, the vertical pipe is more stable when being welded by pressing down the fixing tube, and will not shake, which is conducive to welding by the staff, and prevents the vertical pipe from shaking during the welding process and affecting the welding quality. The anti-slip sleeve increases the friction between the fixing tube and the vertical pipe, and the vertical pipe is not easy to shake.

The second servo motor drives the rotating disk to rotate, and the position to be welded can be rotated to the bottom of the vertical tube, which is convenient for connecting the vertical tube with the copper tube. The anti-slip pad increases friction, making the copper tube more stable.

[0015] 3. In the utility model, after the copper tube is placed, the fixing frame is connected to the support block, and then the threaded rod is rotated to drive the fixing block to descend and squeeze and fix the copper tube. Since the fixing block is made of wear-resistant rubber material, the fixing block deforms and fixes the copper tube after contacting the copper tube, thereby further enhancing the stability of the copper tube and improving the welding quality.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1-5A welding mold for a condenser copper tube is shown, comprising a base plate 1, a mounting seat 2 is welded to one end of the top outer wall of the base plate 1, a fixing component is arranged on the top outer wall of the mounting seat 2, the fixing component comprises a mounting frame 3 rotatably mounted on the top outer wall of the mounting frame 2, a mounting hole is opened on the top outer wall of the mounting frame 3, an electric telescopic rod 4 is mounted on the inner wall of the mounting hole, a mounting plate 5 is mounted on the end of the electric telescopic rod 4, a fixing cylinder 6 is rotatably mounted on the bottom outer wall of the mounting plate 5 by a thread, the fixing cylinder 6 is circular, a supporting component is rotatably mounted on the top outer wall of the base plate 1, the supporting component is located below the fixing component, the supporting component is matched with the fixing component, an anti-slip sleeve 7 is arranged on the inner wall of the fixing cylinder 6, the anti-slip sleeve 7 is matched with the fixing cylinder 6, and the thickness of the anti-slip sleeve 7 is less than the thickness of the fixing cylinder 6.

[0025] By means of the above structure: during operation, the copper tube to be welded is fixed by the supporting assembly. After the fixing is completed, the vertical tube to be welded is inserted into the fixing tube 6 for fixing. Then the electric telescopic rod 4 drives the fixing tube 6 to descend and then descends the vertical tube connected thereto so that it contacts the copper tube to be welded. The fixing tube 6 applies pressure to the vertical tube so that the vertical tube and the copper tube fit tightly together, which is convenient for welding. Compared with the traditional manual fixing method, the vertical tube is more stable when welded by pressing down the fixing tube 6 and will not shake, which is beneficial for the staff to weld and prevents the vertical tube from shaking during the welding process and affecting the welding quality. The anti-slip sleeve 7 increases the friction between the fixing tube 6 and the vertical tube, and the vertical tube is not easy to shake. At the same time, the fixing tube 6 is rotatably connected to the mounting plate 5 and can be replaced according to the specifications of the welded vertical tube, and a fixing tube 6 suitable for the vertical tube can be selected.

[0026] like Figure 4 As shown, a connecting shaft is provided on the outer wall at the bottom of the mounting frame 3, and the connecting shaft is rotatably connected to the mounting seat 2. A driving groove is opened inside the mounting seat 2, and a first servo motor 8 is installed on the inner wall of the driving groove. The output shaft of the first servo motor 8 is connected to the rotating shaft. The first servo motor 8 drives the mounting frame 3 to rotate, which is convenient for connecting the vertical pipe with the fixed tube 6 and preventing the support assembly from hindering the installation of the vertical pipe.

[0027] like Figure 3As shown, the support assembly includes a rotating groove opened on the outer wall of the top of the base plate 1, a rotating disk 9 is rotatably installed on the inner wall of the rotating groove, a support block 10 is welded on the outer wall of the top of the rotating disk 9, and the support block 10 is arc-shaped. A control groove is opened inside the base plate 1, and a second servo motor 13 is installed on the inner wall of the control groove. The output shaft of the second servo motor 13 is connected to the rotating disk 9, and a support groove 11 is opened on the top of the support block 10. The support groove 11 is adapted to the support block 10, and an anti-skid pad 12 adapted thereto is provided on the inner wall of the support groove 11. When the vertical pipe is welded to the copper pipe, since the copper pipe is round, it is placed inside the support groove 11 when it is fixed. The support groove 11 fixes the copper pipe, and the copper pipe cannot move during welding, which can keep the copper pipe stable and facilitate welding. The second servo motor 13 drives the rotating disk 9 to rotate, and can rotate the position to be welded to the bottom of the vertical pipe, which is convenient for the vertical pipe to be connected to the copper pipe. The anti-skid pad 12 increases friction, making the copper pipe more stable.

[0028] like Figure 5 As shown, a fixing frame 14 is inserted on the top of the support block 10, and the fixing frame 14 is a "C"-shaped structure. A threaded rod 15 is rotatably installed on the top of the fixing frame 14, and a fixing block 16 is rotatably installed on the end of the threaded rod 15. The fixing block 16 is made of wear-resistant rubber material. Fixing pins 17 are provided at both ends of the bottom outer wall of the fixing frame 14, and fixing holes 18 are provided at both ends of the top outer wall of the support block 10. The fixing pins 17 are adapted to the fixing holes 18, and magnetic blocks are provided at the bottom of the fixing pin 17 and the inner wall of the fixing hole 18. After the copper tube is placed, the fixing frame 14 is connected to the support block 10, and then the threaded rod 15 is rotated to drive the fixing block 16 to descend and squeeze and fix the copper tube. Since the fixing block 16 is made of wear-resistant rubber material, the fixing block 16 deforms according to the copper tube after contacting the copper tube and fixes it, thereby further enhancing the stability of the copper tube and thus improving the welding quality.

[0029] How this utility works:

[0030] During work, the copper pipe to be welded is fixed by the supporting assembly. After the fixing is completed, the vertical pipe to be welded is inserted into the fixing tube 6 for fixing. Then the electric telescopic rod 4 drives the fixing tube 6 to descend and then descends the vertical pipe plugged therein so that it contacts the copper pipe to be welded. The fixing tube 6 applies pressure to the vertical pipe so that the vertical pipe and the copper pipe fit closely together, which is convenient for welding. Compared with the traditional manual fixing method, the fixing tube 6 is pressed down and fixed, and the vertical pipe is more stable during welding and will not shake, which is beneficial for the staff to weld and prevents the vertical pipe from shaking during the welding process and affecting the welding quality. The anti-slip sleeve 7 increases the friction between the fixing tube 6 and the vertical pipe, and the vertical pipe is not easy to shake. At the same time, the fixing tube 6 is rotatably connected to the mounting plate 5 and can be replaced according to the specifications of the welded vertical pipe, and the fixing tube 6 suitable for the vertical pipe is selected;

[0031] When the vertical tube is welded with the copper tube, since the copper tube is round, it is placed inside the support groove 11 when it is fixed. The support groove 11 fixes the copper tube, and the copper tube cannot move during welding, which can keep the copper tube stable and facilitate welding. The second servo motor 13 drives the rotating disk 9 to rotate, and the position to be welded can be rotated to the bottom of the vertical tube, which is convenient for connecting the vertical tube with the copper tube. The anti-skid pad 12 increases friction, making the copper tube more stable.

[0032] After the copper tube is placed, the fixing frame 14 is connected to the supporting block 10, and then the threaded rod 15 is rotated to drive the fixing block 16 to descend and squeeze and fix the copper tube. Since the fixing block 16 is made of wear-resistant rubber material, the fixing block 16 deforms and fixes the copper tube after contacting the copper tube, further enhancing the stability of the copper tube and thus improving the welding quality.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
