Description

Technical Field

[0001] This invention relates to the field of fin welding technology, and more specifically to an auxiliary device for welding household air conditioner pipe fittings. Background Technology

[0002] An air conditioner's radiator mainly consists of heat dissipation pipes and fins. The function of the fins is to increase the heat dissipation area and improve heat dissipation efficiency. Through welding, the fins can be tightly bonded to the heat dissipation pipes, ensuring that heat can be efficiently transferred from the heat dissipation pipes to the fins, thus allowing the heat generated by the air conditioner during cooling or heating to be quickly dissipated into the surrounding environment.

[0003] To further expand the heat transfer area and enhance heat transfer performance, the fins are arranged in a dense pattern. Existing technologies for welding densely arranged fins present the following technical problems; First, because the spacing between the densely arranged fins is generally less than 1.5mm, it is difficult for the welding nozzle of a regular welding machine to directly insert between the fins for welding, resulting in welding difficulties.

[0004] Secondly, since household seamless tubes are mostly thin-walled tubes, the high temperature generated by welding components is conducted to the seamless tube, and the high temperature of the seamless tube is conducted to the adjacent fins, causing the unwelded fins to stick to the seamless tube. As welding continues, the seamless tube accumulates heat, and the area of ​​adhesion of the annular fins increases. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an auxiliary device for welding household air conditioning pipes.

[0006] The objective of this invention can be achieved through the following technical solutions: A welding auxiliary device for household air conditioner pipe fittings includes a workbench and a heat dissipation pipe. The heat dissipation pipe includes a seamless tube and annular fins. A pipe fitting mounting frame and a guide platform are mounted on the workbench. The pipe fitting mounting frame includes a bracket and a rotating frame. A rotating sleeve is mounted on the bracket. One end of the seamless tube is inserted into the rotating sleeve, and the other end is rotatably connected to the rotating frame. The guide platform includes a side guide platform and a guide frame. A driving component is mounted on the guide platform, and an adjusting component is slidably mounted inside the side guide platform. The driving component drives the adjusting component to move. Several support plate assemblies are slidably mounted inside the guide frame. Each support plate assembly includes a slide base and a side block and a side plate slidably mounted on the slide base. Side block two and the slide block are connected by spring three. Placement slots are opened on side block one and side block two, and annular fins are inserted into the placement slots. The adjustment assembly includes a guide seat and a lifting frame that can be raised and lowered on the top of the guide seat. Welding components are installed on the lifting frame. An inner wall plate is installed on the inner side of the lifting frame. A U-shaped insert rod is slidably installed on the inner wall plate. A push rod is rotatably installed on the inner wall plate. Guide holes and insertion holes are opened on the top of side block one and side block two. The U-shaped insert rod is inserted into the guide hole and insertion hole of the corresponding support plate assembly. Push blocks are installed on the top of side block one and side block two. The push rod pushes the adjacent support plate assembly to move through the push block.

[0007] As a further aspect of the present invention: a top plate is installed at the bottom of the inner wall panel, and the top plate fixes the starting angle of the push rod, causing the push rod to be in an inclined state.

[0008] As a further embodiment of the present invention: a rotating head is rotatably mounted on the inner wall plate, a guide groove is opened inside the rotating head, a push rod slides inside the guide groove, and the push rod is connected to the inner wall of the guide groove by a spring.

[0009] As a further embodiment of the present invention: sliders are installed at the bottom of the first side block and the second side block, and a slanted groove is opened at the top of the slide block. The slider slides inside the slanted groove, and the slider is connected to the inner wall of the slanted groove by a second spring.

[0010] As a further aspect of the present invention: the insertion hole is connected to the placement groove, and a push plate is horizontally slidably installed inside the insertion hole. The push plate is connected to a side block one through a guide rod, and the push plate is connected to the inner wall of the insertion hole through a spring one. When the U-shaped plug is inserted into the insertion hole, the U-shaped plug pushes the push plate towards the placement groove through the inclined surface on the push plate.

[0011] As a further aspect of the present invention: a cylinder is installed on the guide seat, and the cylinder drives the lifting frame to move up and down; the driving assembly includes a second motor installed on the workbench, the output end of the second motor is connected to a lead screw, and the lead screw is connected to the guide seat in a transmission connection.

[0012] As a further aspect of the present invention: a motor is mounted on the workbench, and the motor is connected to a rotating sleeve via a belt.

[0013] The beneficial effects of this invention are: (1) During welding, the cylinder drives the lifting frame to move downward, which in turn moves the welding assembly downward. Simultaneously, the lifting frame moves the U-shaped insert and push rod downward through the inner wall plate. As the U-shaped insert moves downward, it inserts into the corresponding guide hole and insertion hole, fixing the position of the annular fin to be welded. As the push rod moves downward, it pushes the push blocks on the adjacent side block one and side block two to move, causing the adjacent annular fins to move away from each other. This increases the spacing between the annular fins at the welding location, ensuring that the welding nozzle of the welding assembly can extend into the gap between the annular fins, thus achieving welding of densely arranged annular fins.

[0014] (2) At the beginning of welding, when the lifting frame moves down, the U-shaped insert rod is inserted into the guide hole and insertion hole corresponding to the first annular fin. At this time, the push rod pushes the subsequent annular fins through the support plate assembly to prevent adjacent annular fins from sticking to the seamless tube. As welding continues, the number of support plate assemblies pushed by the push rod decreases, the spring in the rotating head rebounds, the push rod extends out from inside the guide groove, and the distance the push rod pushes the adjacent annular fins increases, preventing the annular fins from sticking to the seamless tube due to the accumulation of heat.

[0015] (3) When the lifting frame of the present invention moves down, the U-shaped plug is inserted into the plug hole. At this time, the U-shaped plug pushes the push plate to move towards the placement groove through the inclined surface on the push plate. The inclined surface supports the unwelded side of the annular fin, preventing the annular fin from bending towards the unwelded side when welding one side of the annular fin.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-11As shown, this invention is an auxiliary device for welding household air conditioner pipe fittings, comprising a workbench 1 and a heat dissipation pipe 7. The heat dissipation pipe 7 includes a seamless pipe 701 and annular fins 702. A pipe fitting mounting bracket 2 and a guide platform 3 are mounted on the workbench 1. The pipe fitting mounting bracket 2 includes a support 202 and a rotating bracket 205. A rotating sleeve 203 is mounted on the support 202. One end of the seamless pipe 701 is inserted into the rotating sleeve 203, and the other end is rotatably connected to the rotating bracket 205. The guide platform 3 includes a side guide platform 301 and a guide frame 302. A driving assembly 4 is mounted on the guide platform 3. An adjusting assembly 5 is slidably mounted inside the side guide platform 301. The driving assembly 4 drives the adjusting assembly 5 to move. Several support plate assemblies 6 are slidably mounted inside the guide frame 302. Each support plate assembly 6 includes a slide block 601 and two side blocks 602 and 603 slidably mounted on the slide block 601. The components are connected by a spring 604. Placement slots 609 are provided on side blocks 602 and 603, and annular fins 702 are inserted into the placement slots 609. The adjustment assembly 5 includes a guide seat 501 and a lifting frame 502 mounted on top of the guide seat 501. A welding assembly 8 is installed on the lifting frame 502. An inner wall plate 504 is installed on the inner side of the lifting frame 502. A U-shaped insert rod 505 is slidably installed on the inner wall plate 504, and a push rod 506 is rotatably installed on the inner wall plate 504. Guide holes 610 and insertion holes 611 are provided on the top of side blocks 602 and 603. The U-shaped insert rod 505 is inserted into the guide holes 610 and insertion holes 611 of the corresponding support plate assembly 6. A push block 605 is installed on the top of side blocks 602 and 603, and the push rod 506 pushes the adjacent support plate assembly 6 to move through the push block 605.

[0021] Specifically, a top plate 508 is installed at the bottom of the inner wall panel 504, and the top plate 508 fixes the starting angle of the push rod 506, causing the push rod 506 to be in an inclined state. Specifically, a rotating head 507 is rotatably installed on the inner wall panel 504, and a guide groove 510 is opened inside the rotating head 507. The push rod 506 slides inside the guide groove 510, and the push rod 506 is connected to the inner wall of the guide groove 510 through a spring 509.

[0022] Specifically, a cylinder 503 is installed on the guide seat 501, and the cylinder 503 drives the lifting frame 502 to rise and fall; the drive assembly 4 includes a second motor 401 installed on the workbench 1, the output end of the second motor 401 is connected to a lead screw 402, and the lead screw 402 is connected to the guide seat 501 in a transmission connection. Specifically, a first motor 201 is installed on the workbench 1, and the first motor 201 is connected to the rotating sleeve 203 through a belt 204.

[0023] It should be noted that; Before welding, insert the annular fins 702 into the placement slots 609 on the side block 1 602 and the side block 2 603. After all the annular fins 702 are installed, pass the seamless tube 701 through the annular fins 702, so that one end of the seamless tube 701 is inserted into the rotating sleeve 203 and the other end is installed on the rotating frame 205.

[0024] Furthermore, the inner diameter of the annular fin 702 in this invention is slightly larger than the diameter of the seamless tube 701, ensuring convenient installation of the seamless tube 701. Since the seamless tubes 701 used in household air conditioners are mostly thin-walled, the design of the annular fin 702 having a larger inner diameter than the seamless tube 701 prevents the annular fin 702 from scratching the tube wall during installation, thus avoiding perforation and leakage. Specifically, the support assemblies 6 are tightly fitted together by springs 604, thereby controlling the distance between each annular fin 702 to conform to the calibrated distance.

[0025] During welding, cylinder 503 drives lifting frame 502 to move downwards, and lifting frame 502 drives welding assembly 8 to move downwards synchronously. At the same time, lifting frame 502 drives U-shaped insert rod 505 and push rod 506 to move downwards synchronously through inner wall plate 504. As U-shaped insert rod 505 moves downwards, the two sides of U-shaped insert rod 505 are inserted into guide holes 610 and insertion holes 611 on corresponding side block 1 602 and side block 2 603, respectively. The position of the annular fin 702 to be welded is fixed by inserting U-shaped insert rod 505 into guide holes 610 and insertion holes 611. As the lifting frame 502 moves downward, the U-shaped insert 505 applies pressure to the side block 602 and the side block 603. Through the cooperation of the slider 606 at the bottom of the side block 602 and the oblique groove 608 on the slide block 601, the side blocks 602 and the side block 603 move closer to each other. The side blocks 602 and the side block 603 apply pressure to the annular fin 702, so that the annular fin 702 fits against the seamless tube 701. This avoids the annular fin 702 being unwelded due to the design that the inner diameter of the annular fin 702 is larger than the diameter of the seamless tube 701.

[0026] Because the top plate 508 fixes the angle of the push rod 506, the push rod 506 is tilted. As the push rod 506 moves down, it pushes the push block 605 on the adjacent side block 1 602 and side block 2 603 to move, causing the adjacent annular fins 702 to move away from each other. The distance between the annular fins 702 at the welding part increases, ensuring that the welding nozzle of the welding assembly 8 can extend into the gap between the annular fins 702, so as to realize the welding of the densely arranged annular fins 702.

[0027] It should be noted that household seamless tubes 701 are mostly thin-walled tubes. The high temperature generated by welding component 8 is conducted to seamless tube 701, and the high temperature of seamless tube 701 is conducted to the adjacent annular fins 702, causing the unwelded annular fins 702 to stick to seamless tube 701. As welding continues, seamless tube 701 accumulates heat, and the sticking range of annular fins 702 increases.

[0028] Therefore, at the beginning of welding, when the lifting frame 502 moves down, the U-shaped insert rod 505 is inserted into the guide hole 610 and insertion hole 611 corresponding to the first annular fin 702. At this time, the push rod 506 pushes the subsequent annular fin 702 through the support plate assembly 6 to prevent the adjacent annular fin 702 from sticking to the seamless tube 701. At this time, there are a large number of annular fins 702. The push rod 506 retracts into the guide groove 510 and compresses the spring 4 509.

[0029] As welding continues, the number of support plate assemblies 6 pushed by push rod 506 decreases, the spring 509 in the rotating head 507 rebounds, push rod 506 extends out from inside guide groove 510, and push rod 506 pushes the adjacent annular fins 702 a greater distance to prevent the annular fins 702 from sticking together due to heat accumulation in seamless tube 701, which would otherwise cause the adjacent annular fins 702 to stick to seamless tube 701.

[0030] Furthermore, the present invention uses a second motor 401 to drive a lead screw 402 to rotate. The lead screw 402, connected to a guide seat 501, drives the adjusting assembly 5 to slide, causing the welding assembly 8 on the adjusting assembly 5 to move axially along the seamless tube 701 and weld the corresponding annular fins 702 one by one. A first motor 201 drives the seamless tube 701 to rotate via a belt 204, ensuring that the welding assembly 8 can weld along the circumference of the seamless tube 701, thus improving welding accuracy.

[0031] See Figures 10-12 The bottom of the first side block 602 and the second side block 603 are equipped with sliders 606. The top of the slide block 601 has an inclined groove 608. The slider 606 slides inside the inclined groove 608, and the slider 606 is connected to the inner wall of the inclined groove 608 by a second spring 607. Specifically, the insertion hole 611 is connected to the placement groove 609. A push plate 612 is horizontally slidably installed inside the insertion hole 611. The push plate 612 is connected to the first side block 602 by a guide rod 614, and the push plate 612 is connected to the inner wall of the insertion hole 611 by a first spring 613. When the U-shaped insertion rod 505 is inserted into the insertion hole 611, the U-shaped insertion rod 505 pushes the push plate 612 toward the placement groove 609 through the inclined surface 615 on the push plate 612.

[0032] It should be noted that household seamless tubes 701 are mostly thin-walled tubes. To prevent the seamless tube 701 from puncturing, the annular fin 702 uses a single-sided welding process. When welding one side of the annular fin 702, the material on that side expands due to the increased temperature. Since the other side is not heated, the expansion is smaller, causing the annular fin 702 to bend towards the unwelded side.

[0033] Based on this, when the lifting frame 502 of the present invention moves down, the U-shaped insert rod 505 is inserted into the insertion hole 611. At this time, the U-shaped insert rod 505 pushes the push plate 612 to move towards the placement groove 609 through the inclined surface 615 on the push plate 612. The inclined surface 615 supports the unwelded side of the annular fin 702, preventing the annular fin 702 from bending towards the unwelded side when welding one side of the annular fin 702.

[0034] The implementation principle of this invention is as follows: Before welding, insert the annular fins 702 into the placement slots 609 on the side block 1 602 and the side block 2 603. After all the annular fins 702 are installed, pass the seamless tube 701 through the annular fins 702, so that one end of the seamless tube 701 is inserted into the rotating sleeve 203 and the other end is installed on the rotating frame 205.

[0035] Furthermore, the inner diameter of the annular fin 702 of the present invention is slightly larger than the diameter of the seamless tube 701, ensuring convenient installation of the seamless tube 701. This design, where the inner diameter of the annular fin 702 is larger than the diameter of the seamless tube 701, prevents the annular fin 702 from scratching the tube wall during installation, thus avoiding perforation and leakage. Specifically, the support assemblies 6 are tightly fitted together by springs 604, thereby controlling the distance between each annular fin 702 to conform to the calibrated distance.

[0036] During welding, cylinder 503 drives lifting frame 502 to move downwards, and lifting frame 502 drives welding assembly 8 to move downwards synchronously. At the same time, lifting frame 502 drives U-shaped insert rod 505 and push rod 506 to move downwards synchronously through inner wall plate 504. As U-shaped insert rod 505 moves downwards, the two sides of U-shaped insert rod 505 are inserted into guide holes 610 and insertion holes 611 on corresponding side block 1 602 and side block 2 603, respectively. The position of the annular fin 702 to be welded is fixed by inserting U-shaped insert rod 505 into guide holes 610 and insertion holes 611. As the lifting frame 502 continues to move downward, the U-shaped insert 505 applies pressure to the side block 602 and the side block 603. Through the cooperation of the slider 606 at the bottom of the side block 602 and the oblique groove 608 on the slide block 601, the side block 602 and the side block 603 move closer to each other. The side block 602 and the side block 603 apply pressure to the annular fin 702, so that the annular fin 702 fits against the seamless tube 701. This avoids the annular fin 702 being unwelded due to the design that the inner diameter of the annular fin 702 is larger than the diameter of the seamless tube 701.

[0037] Because the top plate 508 fixes the angle of the push rod 506, the push rod 506 is tilted. When the push rod 506 moves down, it pushes the push block 605 on the adjacent side block 1 602 and side block 2 603 to move, causing the adjacent annular fins 702 to move away from each other. This increases the spacing between the annular fins 702 at the welding part, ensuring that the welding nozzle of the welding assembly 8 can extend into the gap between the annular fins 702, thus achieving welding of the densely arranged annular fins 702.

[0038] It should be noted that household seamless tubes 701 are mostly thin-walled tubes. The high temperature generated by welding component 8 is conducted to seamless tube 701, and the high temperature of seamless tube 701 is conducted to the adjacent annular fins 702, causing the unwelded annular fins 702 to stick to seamless tube 701. As welding continues, seamless tube 701 accumulates heat, and the sticking range of annular fins 702 increases.

[0039] Therefore, at the beginning of welding, when the lifting frame 502 moves down, the U-shaped insert rod 505 is inserted into the guide hole 610 and insertion hole 611 corresponding to the first annular fin 702. At this time, the push rod 506 pushes the subsequent annular fin 702 through the support plate assembly 6 to prevent the adjacent annular fin 702 from sticking to the seamless tube 701. At this time, there are a large number of annular fins 702. The push rod 506 retracts into the guide groove 510 and compresses the spring 4 509.

[0040] As welding continues, the number of support plate assemblies 6 pushed by push rod 506 decreases, the spring 509 in the rotating head 507 rebounds, push rod 506 extends out from inside guide groove 510, and push rod 506 pushes the adjacent annular fins 702 a greater distance to prevent the annular fins 702 from sticking together due to heat accumulation in seamless tube 701, which would otherwise cause the adjacent annular fins 702 to stick to seamless tube 701.

[0041] It should be noted that household seamless tubes 701 are mostly thin-walled tubes. To prevent the seamless tube 701 from puncturing, the annular fin 702 uses a single-sided welding process. When welding one side of the annular fin 702, the material on that side expands due to the increased temperature. Since the other side is not heated, the expansion is smaller, causing the annular fin 702 to bend towards the unwelded side.

[0042] Based on this, when the lifting frame 502 of the present invention moves down, the U-shaped insert rod 505 is inserted into the insertion hole 611. At this time, the U-shaped insert rod 505 pushes the push plate 612 to move towards the placement groove 609 through the inclined surface 615 on the push plate 612. The inclined surface 615 supports the unwelded side of the annular fin 702, preventing the annular fin 702 from bending towards the unwelded side when welding one side of the annular fin 702.
