Description

Technical Field

[0001] This invention relates to the field of low-temperature welding technology for air conditioning copper pipes, specifically to a low-temperature welding auxiliary device for air conditioning copper pipes. Background Technology

[0002] In the installation and maintenance of air conditioners, low-temperature welding of copper pipes is a crucial process to ensure the sealing of the pipeline and the stability of the system operation. Currently, the industry generally uses manual clamping combined with welding gun operation to complete the welding. The core relies on the clamp to position and fix the copper pipes, and then manual adjustment to achieve the connection of the copper pipes to be welded.

[0003] For example, an auxiliary device with application number CN109702414B relates to a stool frame welding auxiliary device. Therefore, the technical problem of this invention is to provide a stool frame welding auxiliary device that can fix a U-shaped frame, facilitating welding without affecting the welding effect, and eliminating the need for constant movement. The technical implementation of this invention is as follows: a stool frame welding auxiliary device includes a support, a rotating shaft, and a first fixing plate; the upper middle part of the support has a rotating shaft, and the front end of the rotating shaft is fixedly connected to the first fixing plate. This invention, through the action of the swinging block and the first fixing plate, can fix the U-shaped frame, allowing people to weld the U-shaped frame without having to hold it down by hand, avoiding hand tremors affecting the welding effect. Furthermore, by rotating the second fixing plate, the welding point of the U-shaped frame can be rotated upwards, facilitating welding. The swinging handle further enhances the ease of rotating the U-shaped frame, improving work efficiency. However, the clamping distance adjustment range of the auxiliary device is narrow, making it difficult to be compatible with copper pipes of various diameters. When welding copper pipes of different diameters, special clamps need to be replaced, resulting in poor versatility and low adjustment efficiency. Most devices require manual adjustment of the clamping structures of the two sets of copper pipes to be welded, making synchronous adjustment impossible. Moreover, the adjustment process is cumbersome and consumes a lot of preparation time.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a low-temperature welding aid for air conditioning copper pipes. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a low-temperature welding aid for air conditioning copper pipes, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-temperature welding auxiliary device for air conditioning copper pipes, comprising a fixing component one and a clamp one. The fixing component one is internally provided with a driving assembly for auxiliary fixing, and the driving assembly includes a drive gear, a transmission gear and a threaded rod. The transmission gear is meshed on the outer surface of the drive gear, and a threaded rod is provided in the middle of one side of the transmission gear. A clamp two is threadedly installed on the outer surface of one end of the threaded rod. The clamp one is fixedly disposed on the outer surface of one side of the fixing component one, and a copper pipe one is installed between the fixing component one and the fixing component one. A copper pipe two is provided at the end of the copper pipe one, and a fixing component two is provided on the outside of the copper pipe two.

[0007] Furthermore, the first and second fixing components have the same structure, and the top outer surfaces of the first and second fixing components are fixed with connecting seats by bolts.

[0008] Furthermore, the connecting seat is provided with a lead screw inside, and there are two sets of connecting seats, one set of which is threadedly connected to one end of the lead screw.

[0009] Furthermore, a shaft is connected to the middle of one side of the drive gear, and a fixing member is rotatably connected to the shaft. A threaded layer is provided on the outer surface of one end of the shaft, and a nut is threadedly installed on the outer surface of one end of the shaft.

[0010] Furthermore, a side plate is provided on one side of the interior of both the first and second fixing members, and the side plate has a rectangular structure.

[0011] Furthermore, a guide rod is slidably installed inside the second clamp, and the guide rod is fixedly disposed on one side of the clamp.

[0012] Furthermore, an auxiliary component for linkage control locking is provided on the outer side of the first and second fixing components, and the auxiliary component includes a fixing block, a hydraulic rod and a telescopic rod. The bottom of the fixing block is provided with a hydraulic rod, and the output end of the hydraulic rod is equipped with the telescopic rod.

[0013] Furthermore, the auxiliary component also includes a second telescopic rod and a rack, and the second telescopic rod is slidably disposed inside the first telescopic rod, and a rack is installed at one end of both the first and second telescopic rods.

[0014] Furthermore, the rack is engaged on one side of the drive gear, and a groove is provided on one side of the fixing member, and the fixing member is slidably connected to the rack through the groove.

[0015] Furthermore, the diameter of the drive gear is three times that of the transmission gear, and there are two sets of transmission gears.

[0016] This invention provides a low-temperature welding aid for air conditioning copper pipes, which has the following beneficial effects: 1. This low-temperature welding auxiliary device for air conditioning copper pipes, through the meshing transmission structure of the active gear and two sets of transmission gears, combined with the threaded connection design of the threaded rod and the second clamp, can quickly adjust the distance between the first clamp and the second clamp. The first and second fixing parts have the same structure, which can stably clamp copper pipes of different diameters. At the same time, with the sliding guidance of the guide rod, the movement of the clamp is ensured to be smooth during the adjustment process. This solves the problem that traditional clamps are difficult to adapt to copper pipes of multiple specifications, and significantly improves the versatility of the welding auxiliary device.

[0017] 2. This low-temperature welding auxiliary device for air conditioning copper pipes, through the linkage design of auxiliary components and drive components, achieves the coordinated action of the entire chain of hydraulic rod telescopic rod one, telescopic rod two, rack, drive gear, transmission gear, clamp one, and clamp two. It can synchronously drive two sets of clamps to complete clamping and adjustment, which not only avoids the cumbersome operation caused by manual adjustment, but also ensures the synchronicity of the adjustment of the two sets of clamps. With the guiding effect of guide rod and slide, the stability and accuracy of clamp adjustment are further improved, helping copper pipe one and copper pipe two to quickly achieve coaxial docking, laying the foundation for high-quality welding, while significantly reducing the difficulty and intensity of manual operation.

[0018] 3. This low-temperature welding aid for air conditioning copper pipes features a 3:1 gear ratio design between the drive gear and the transmission gear, which accelerates the adjustment speed of the clamp. Combined with the sliding guide of the rack on the first fixing part, it further improves the efficiency of pre-welding preparation and reduces manual operation intensity. The shaft is threadedly fixed by a nut, ensuring that copper pipe one and copper pipe two maintain axial alignment during welding, effectively preventing misalignment and shaking. Simultaneously, the transmission design of the lead screw and connecting seat allows rotation of the handle to drive the connecting seat, smoothly connecting the first and second fixing parts and the copper pipe, reducing weld defects caused by interface misalignment and significantly improving the welding pass rate.

[0021] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0022] like Figures 1-5As shown, the present invention provides a technical solution: a low-temperature welding auxiliary device for air conditioning copper pipes, comprising a fixing component 1, a fixing component 2, a copper pipe 3, a copper pipe 4, a clamp 1, a clamp 2, a handle 7, an auxiliary assembly 8, a fixing block 801, a hydraulic rod 802, a telescopic rod 1 803, a telescopic rod 2 804, a rack 805, a connecting seat 9, a lead screw 10, a nut 11, a side plate 12, a shaft 13, a drive assembly 14, a drive gear 1401, a transmission gear 1402, a threaded rod 1403, a slide groove 15, and a guide rod 16. The fixing component 1 has a drive assembly 14 for auxiliary fixing inside, and the drive assembly 14 includes a drive gear 1401, a transmission gear 1402, and a threaded rod 1403. The diameter of the drive gear 1401 is... It is three times the size of the transmission gear 1402, and the transmission gear 1402 is provided in two sets. Side plates 12 are provided on one side of the interior of fixing part 1 and fixing part 2, and the side plates 12 have a rectangular structure. Fixing part 1 and fixing part 2 have the same structure, and connecting seats 9 are fixedly installed on the top outer surface of fixing part 1 and fixing part 2 by bolts. A lead screw 10 is provided inside the connecting seat 9, and there are two sets of connecting seats 9. One set of connecting seats 9 is threadedly connected to one end of the lead screw 10, and a handle 7 is fixedly installed on one end of the lead screw 10. The transmission gear 1402 is meshed on the outer surface of the driving gear 1401, and a threaded rod 1403 is provided in the middle of one side of the transmission gear 1402. A shaft 13 is connected to the middle of one side of the driving gear 1401, and the fixing part... Fixture 11 is rotatably connected to shaft 13, and one end of shaft 13 has a threaded layer on its outer surface. A nut 11 is threaded onto one end of shaft 13. A clamp 6 is threaded onto one end of threaded rod 1403. A guide rod 16 is slidably mounted inside clamp 6, and the guide rod 16 is fixedly mounted on one side. Fixture 5 is fixedly mounted on one side of the outer surface of fixture 1, and a copper tube 3 is installed between fixture 1 and fixture 6. A copper tube 4 is attached to the end of copper tube 3, and a fixture 2 is attached to the outside of copper tube 4. During welding, the copper tubes 3 and 4 to be welded are placed between fixture 5 and fixture 6 respectively. When the diameters of fixtures 5 and 6 are different, the user can... The rotation of the drive gear 1401 drives the rotation of two sets of transmission gears 1402. Through the design of the gear ratio between the two gears, the rotation of the transmission gear 1402 can quickly rotate the threaded rod 1403, thereby driving the clamp 2 6 on the outer surface of the threaded rod 1403 to move horizontally about the guide rod 16. This allows control of the distance between clamp 1 5 and clamp 2 6. Fixing part 1 1 and fixing part 2 2 have the same structure, which facilitates the quick clamping and fixing of copper tube 1 3 and copper tube 2 4 of different diameters. After the position is adjusted, the design of the nut 11 can be used to thread the shaft 13 about fixing part 1 or fixing part 2, ensuring that the weld joint of copper tube 1 3 and copper tube 2 4 remains axially consistent during the welding process, is stable and does not wobble, and improves the welding quality.

[0023] like Figures 3-6 As shown, an auxiliary component 8 for linkage control locking is provided on one side of the fixing component 1 and the fixing component 2. The auxiliary component 8 includes a fixing block 801, a hydraulic rod 802, and a telescopic rod 803. The bottom of the fixing block 801 is provided with the hydraulic rod 802, and the output end of the hydraulic rod 802 is equipped with the telescopic rod 803. The auxiliary component 8 also includes a telescopic rod 804 and a rack 805. The telescopic rod 804 is slidably arranged inside the telescopic rod 803. A rack 805 is installed at one end of both the telescopic rod 803 and the telescopic rod 804. The rack 805 is meshed with one side of the drive gear 1401. A groove 15 is opened on one side of the fixing component 1, and the fixing component 1 is slidably connected to the rack 805 through the groove 15. When the diameters of the copper pipe 3 and the copper pipe 4 are the same, the design of the hydraulic rod 802 can drive the telescopic rod. The first 803 and the second 804 move up or down, causing the rack 805 connected to the first 803 and the second 804 to move accordingly. As the first 803 and the second 804 move up or down, they can drive the two sets of drive gears 1401 to rotate synchronously. This allows the two sets of clamps 1 and 2 to simultaneously clamp and limit the copper tube 1 3 or copper tube 2 4 located inside them, eliminating the need for individual fixing and making it more efficient. In addition, after the copper tube 1 3 or copper tube 2 4 is fixed between clamps 1 and 2, the user can drive the handle 7 to rotate, causing the lead screw 10 to rotate accordingly. The rotation of the lead screw 10 can drive the connecting seat 9 and the fixing part 1, which are threaded to it, to move in the axial direction, facilitating the stable connection of the clamped copper tube 1 3 and copper tube 2 4, which is beneficial for welding operations.

[0024] In summary, as Figures 1-6 As shown, when using this low-temperature welding auxiliary device for air conditioning copper pipes, the copper pipes to be welded, 3 and 4, are placed between clamps 5 and 6 corresponding to the fixing parts 1 and 2, respectively. The adjustment method is selected according to the diameter of the copper pipes. When the pipe diameters are the same, the auxiliary component 8 is activated for linkage control. When the pipe diameters are different, individual manual adjustment is used.

[0025] When the pipe diameter is the same: Start the hydraulic rod 802 in auxiliary component 8. The output end of hydraulic rod 802 drives telescopic rod one 803 and the internally sliding telescopic rod two 804 to rise and fall synchronously, causing the racks 805 at the ends of the two sets of telescopic rods to slide along the slide groove 15 of the fixing part one 1. The racks 805 mesh with the drive gear 1401 of drive component 14, thereby driving the two sets of drive gears 1401 to rotate synchronously. The drive gear 1401 meshes with the two sets of transmission gears 1402. The diameter of the drive gear is the same as that of the transmission gear. The transmission gear 1402 drives the threaded rod 1403 in the middle to rotate. The threaded rod 1403 is threadedly connected to the clamp 2 6, and the clamp 2 6 slides along the guide rod 16. Finally, it drives the two sets of clamp 2 6 to move closer to clamp 1 5, and simultaneously completes the clamping and fixing of copper tube 1 3 and copper tube 2 4. During the clamping process, the stroke of the hydraulic rod 802 can be finely adjusted by observing the fit between the clamp and the copper tube to avoid damaging the copper tube by clamping too tightly or causing slippage by clamping too loosely. When the pipe diameters are different: manually rotate the shaft 13 to drive the drive gear 1401 to rotate, and adjust the spacing of the clamps 6 of the corresponding fixing parts individually through the gear-threaded rod 1403 transmission link to complete the clamping of copper pipes of different diameters. During adjustment, the guide rod 16 is used to ensure that the clamps 6 move smoothly and avoid deviation. After adjustment, the nut 11 at the end of the shaft 13 is threaded to lock the clamp position firmly and prevent the clamp from loosening during the welding process. After clamping, rotating the handle 7 drives the lead screw 10 to rotate. The lead screw 10 is threadedly connected to a set of connecting seats 9. The connecting seats 9 are fixed to the top of the fixing parts 1 and 2 by bolts, thereby driving the fixing parts 1 to move axially, realizing the precise docking of copper tube 3 and copper tube 4. During the docking process, the handle 7 can be repeatedly finely adjusted. The precision transmission of the lead screw 10 ensures that the docking error is controlled within a reasonable range, ensuring that the axial alignment of the weld is maintained. Throughout the process, the sliding guide rod 16, the slide groove 15, and the position locking nut 11 of the fixture ensure the stability of the copper tube clamping and docking. During welding, the auxiliary component 8 is fixed. The fixed block 801 provides stable support and prevents the hydraulic rod 802 from shifting under force. At the same time, the side plates 12 inside the fixing parts 1 and 2 enhance the overall rigidity of the device, further improving the stability of operation and providing reliable support for subsequent welding operations. In addition, the device can be adapted to various air conditioning installation scenarios. Whether in a confined indoor space or in outdoor operations, the connecting seat 9 can be firmly fixed with bolts to ensure the connection stability of fixing parts 1 and 2 with the main body of the device. With the flexible clamping design of the fixture, the surface of the copper tube is effectively protected from damage, while reducing the intensity of manual gripping and improving welding efficiency and quality.
