Technical Field

[0002] Copper pipes are an indispensable key component in air conditioning refrigeration systems. They are mainly used to connect various components of the air conditioner, such as the compressor, condenser, and evaporator, and bear the important task of refrigerant transmission. Because the refrigerant is in a high-pressure, low-temperature circulating state in the system, the quality requirements for copper pipes are extremely high. Copper pipes must have good corrosion resistance, sealing properties, and thermal conductivity to ensure efficient and stable refrigerant transmission in the system, thereby guaranteeing the cooling or heating effect of the air conditioner.

[0003] Patent CN110900102B discloses a welding device for processing copper pipe joints, including a fixing groove, a welding chamber, and a welding device body. A drive box is fixedly mounted on one side of the welding device body, and a hydraulic press is fixedly mounted on one side inside the drive box. A hydraulic rod is driven on one side of the hydraulic press, and a push rod is fixedly mounted at one end of the hydraulic rod. Feed inlets are fixedly mounted on both sides of the upper surface of the welding device body. A storage chamber is located on the upper inner side of the welding device body, directly below the feed inlets. A second drive motor is mounted on one side of the storage chamber, and rotating shafts are driven on both sides of the second drive motor to relax the fixing clamping plate. At this time, the hydraulic press, through the hydraulic rod, drives the push rod to extend, pushing the welded copper pipe out of the discharge port for manual removal.

[0014] A welding method for a welding apparatus used in processing copper pipe joints for air conditioners includes the following steps: Step 1: When the device is started, the operator first places the air conditioning copper pipe that needs to be welded vertically in the welding area of ​​the support platform. At this time, the motor will start, and the output end of the motor will drive the reciprocating screw to rotate. The rotation of the reciprocating screw will drive the pull rod to rotate. Step 2: At this time, the pull rod 1 is limited by the support platform. The pull rod 1 will cause the moving plate to move laterally in the process of the reciprocating screw rotating. The movement of the moving plate will drive the pull rod 1 to move. The movement of the pull rod 1 will drive the connecting block to move. The movement of the connecting block will drive its own locking block to move. Step 3: Simultaneously, as the connecting block moves, it will also drive the horizontal plate to move. The movement of the horizontal plate will drive the elastic telescopic rod to move, and the movement of the elastic telescopic rod will drive the arc clamping plate to move.

[0016] 2. This welding device for processing air conditioner copper pipe interfaces utilizes the coordinated movement of a hinged column, an L-plate, abutting column, a spring sleeve, a connecting column, a second pulling rod, a first sliding column, a fixed plate, and a semi-arc plate. This movement causes the spring sleeve to contact the parts at the air conditioner copper pipe interface, clamping and fixing them. This improves the stability of the air conditioner copper pipe during welding, enhances welding quality and precision, and maintains stability throughout the welding process.

[0020] 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.

[0021] Please see Figures 1-10 One embodiment of the present invention is: a welding device for processing copper pipe interfaces in air conditioners, comprising a housing 1, a support platform 2 fixedly connected to the inner wall of the housing 1, a reciprocating screw 3 rotatably connected to the inner wall of the housing 1, a reinforcement mechanism 4 for fixing provided on the inner wall of the support platform 2, a protective mechanism 5 for protection provided at the front of the housing 1, a motor fixedly connected to the left side of the housing 1, a movable plate 6 movably connected to the circumferential surface of the reciprocating screw 3, a pulling rod 7 rotatably connected to the circumferential surface of the movable plate 6 via a torsion spring, and a connecting rod 7 rotatably connected to the inner wall of the pulling rod 7 via a torsion spring. Block 8, the top of the support platform 2 is fixedly connected to a vertical groove block 9, the inner wall of the connecting block 8 is fixedly connected to a horizontal plate 10, the right side of the horizontal plate 10 is fixedly connected to an elastic telescopic rod 11, the telescopic end of the elastic telescopic rod 11 is fixedly connected to an arc clamping plate 12, the inner wall of the shell 1 is provided with a multi-angle welding machine, the right side of the moving plate 6 is fixedly connected to a rack 13, the inner wall of the support platform 2 is rotatably connected to a rotating circular plate 14, the circumferential surface of the rotating circular plate 14 is fixedly connected to a slider 15, the bottom of the rotating circular plate 14 is fixedly connected to a toothed ring 16, and the right side of the connecting block 8 is fixedly connected to a locking block; When the device is started, the operator first places the air conditioning copper pipe to be welded vertically on the welding area of ​​the support platform 2. At this time, the motor will start, and the output end of the motor will drive the reciprocating screw 3 to rotate. The rotation of the reciprocating screw 3 will drive the pull rod 7 to rotate. However, at this time, the pull rod 7 is limited by the support platform 2. The pull rod 7 will cause the moving plate 6 to move laterally back and forth through the reciprocating groove on the surface of the reciprocating screw 3 during the rotation of the reciprocating screw 3. The movement of the moving plate 6 will drive the pull rod 7 to move. The movement of lever 7 will cause connecting block 8 to move, which in turn will cause its own locking block to move. Simultaneously, during this movement, connecting block 8 will also cause horizontal plate 10 to move, which in turn will cause elastic telescopic rod 11 to move, which in turn will cause arc clamping plate 12 to move. During the movement of connecting block 8, it will also cause its own locking block to move. After the locking block has moved a certain distance, it will enter the groove of vertical slot block 9 and be guided and limited by vertical slot block 9. At this point, pulling... Rod 7 will continue to move. During the guiding process of the locking block, rod 7 will rotate. The movement of rod 7 will indirectly push connecting block 8 upward within the groove of vertical slot block 9. Simultaneously, as rod 7 continues to move, elastic telescopic rod 11 will cause arc clamping plate 12 to contact the surface of the air conditioning copper pipe and clamp it. The air conditioning copper pipe will simultaneously exert a reaction force, causing arc clamping plate 12 to press against elastic telescopic rod 11. At this time, arc clamping plate 12 will move relatively closer to horizontal plate 10. During the upward movement of connecting block 8... The middle connecting block 8 will drive the horizontal plate 10 to rise, the horizontal plate 10 will drive the elastic telescopic rod 11 to rise, the elastic telescopic rod 11 will drive the arc clamp plate 12 to rise. At this time, the arc clamp plate 12 will slowly rise during the contact with the surface of the air conditioner copper pipe and clamp and fix the upper circumferential surface of the air conditioner copper pipe. At this time, the multi-angle welding machine can weld the air conditioner copper pipe. The movement of the arc clamp plate 12 can ensure the accuracy of the welding position of the air conditioner copper pipe, can closely fit the shape of the air conditioner copper pipe, achieve precise position control, and improve the welding accuracy of the air conditioner copper pipe interface. The reciprocating screw 3 is fixedly connected to the output end of the motor. The pulling rod 7 is in contact with the support platform 2. The connecting block 8 is in contact with the support platform 2. The horizontal plate 10 is in contact with the support platform 2. The arc clamping plate 12 is in contact with the support platform 2 and is used to clamp the air conditioning copper pipe. The slider 15 is in contact with the support platform 2 and is used to reduce the rotational friction of the rotating circular plate 14. The toothed ring 16 is located on the movement trajectory of the rack 13 and the rack 13 is used to drive the toothed ring 16 to rotate. The vertical groove block 9 is located on the movement trajectory of the clamping block. When the device is started, the operator places the air conditioning copper pipe on top of the rotating circular plate 14. During the movement of the moving plate 6, the movement of the moving plate 6 will drive the rack 13 to move. After moving a certain distance, the rack 13 will contact and mesh with the toothed ring 16 before the arc clamp plate 12 contacts the air conditioning copper pipe. At this time, the rack 13 will continue to be driven by the moving plate 6 to move laterally. The continued movement of the rack 13 will cause the toothed ring 16 to rotate. The rotation of the toothed ring 16 will drive the rotating circular plate 14 to rotate. The rotation of the rotating circular plate 14 will drive the slider 15 to rotate. During the rotation of the rotating circular plate 14, the rotation of the rotating circular plate 14 will drive the air conditioning copper pipe placed on its top to rotate. This can adjust the angle and position of the air conditioning copper pipe, improve the welding accuracy of the air conditioning copper pipe, improve the welding efficiency of the air conditioning copper pipe, facilitate manual observation of defects in the air conditioning copper pipe after welding, and improve the welding accuracy of the air conditioning copper pipe of the device.

[0022] Overall working principle: The arc clamp 12 slowly rises during contact with the surface of the air conditioning copper pipe and clamps and fixes the upper circumference of the air conditioning copper pipe. At this time, the multi-angle welding machine can weld the air conditioning copper pipe. The movement of the arc clamp 12 can ensure the accuracy of the welding position of the air conditioning copper pipe, closely fit the shape of the air conditioning copper pipe, achieve precise position control, and improve the welding accuracy of the air conditioning copper pipe interface. During the rotation of the rotating circular plate 14, the rotation of the rotating circular plate 14 will drive the air conditioning copper pipe placed on its top to rotate, which can adjust the angle position of the air conditioning copper pipe, improve the welding accuracy of the air conditioning copper pipe, improve the welding efficiency of the air conditioning copper pipe, facilitate manual observation of the defects produced by the air conditioning copper pipe after welding, and improve the welding accuracy of the air conditioning copper pipe of the device.

[0023] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, the reinforcing mechanism 4 includes a hinge column 401, an L plate 402, an abutment column 403, and a spring sleeve 404. The hinge column 401 is rotatably connected to the inner wall of the horizontal plate 10 by a torsion spring. The L plate 402 is fixedly connected to the circumferential surface of the hinge column 401. The abutment column 403 is fixedly connected to the inner wall of the arc clamp plate 12. The spring sleeve 404 is fixedly connected to the inner wall of the L plate 402. When the device is activated, the movement of the horizontal plate 10 causes the hinge column 401 to move synchronously. During the movement of the hinge column 401, the L plate 402 moves, which in turn moves the spring sleeve 404. Simultaneously with the movement of the horizontal plate 10, the elastic telescopic rod 11 moves, which in turn moves the arc clamp plate 12. The movement of the arc clamp plate 12 synchronously moves the abutment column 403. After the arc clamp plate 12 contacts the surface of the air conditioning copper pipe, the reaction force of the air conditioning copper pipe on the arc clamp plate 12 pushes it relative to the surface. As the arc clamp 12 moves closer to the horizontal plate 10, it drives the abutment column 403 to move. During this movement, the abutment column 403 pushes the L plate 402, causing it to rotate at an angle. This rotation causes the spring sleeve 404 to rotate and move. At this time, the spring sleeve 404 contacts the parts at the interface of the air conditioning copper pipe and clamps and fixes them, which improves the stability of the air conditioning copper pipe during the welding process, enhances the welding quality and precision of the air conditioning copper pipe, and maintains the stability during the welding process. The reinforcement mechanism 4 also includes a connecting column 405, a second pulling rod 406, a first sliding column 407, a fixed plate 408, and a semi-circular plate 409. The connecting column 405 is fixedly connected to the bottom of the rotating circular plate 14. The second pulling rod 406 is rotatably connected to the circumferential surface of the connecting column 405. The first sliding column 407 is slidably connected to the inner wall of the support platform 2. The fixed plate 408 is fixedly connected to the top of the first sliding column 407. The semi-circular plate 409 is fixedly connected to the inner wall of the fixed plate 408. The abutting column 403 is in contact with the L plate 402 and is used to push the L plate 402 to rotate at an angle. The L plate 402 is in contact with the horizontal plate 10. The second pulling rod 406 is rotatably connected to the circumferential surface of the first sliding column 407. The fixed plate 408 is in contact with the support platform 2 and is used to drive the semi-circular plate 409 to move. When the device is started, the rotation of the rotating circular plate 14 will drive the connecting column 405 to rotate. During the rotation of the connecting column 405, the connecting column 405 will drive the second pulling rod 406 to rotate and move. At this time, the second pulling rod 406 will pull the first sliding column 407, causing the first sliding column 407 to move within the groove of the support platform 2. The movement of the first sliding column 407 will drive the fixed plate 408 to move. During the movement of the fixed plate 408, the fixed plate 408 will drive the semi-arc plate 409 to move. After moving a certain distance, the semi-arc plate 409 will contact the surface of the lower area of ​​the air conditioning copper pipe. At this time, multiple semi-arc plates 409 will apply a uniform clamping force, preventing the air conditioning copper pipe from shifting or deforming slightly due to uneven force during welding. This improves the welding efficiency of the device, reduces the generation of air conditioning copper pipes with welding defects, and enhances economic benefits. Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the protective mechanism 5 includes a guide groove plate 501, a reinforcing column 502, an isolation door 503, and a roller 504. The guide groove plate 501 is fixedly connected to the front of the housing 1, the reinforcing column 502 is fixedly connected to the front of the movable plate 6, the isolation door 503 is fixedly connected to the circumferential surface of the reinforcing column 502, and the roller 504 is rotatably connected to the inner wall of the isolation door 503. When the device is started, the lateral movement of the moving plate 6 will drive the reinforcing column 502 to move, the movement of the reinforcing column 502 will drive the isolation door 503 to move, and the movement of the isolation door 503 will drive the roller 504 to move. At this time, the roller 504 will slide in the groove of the guide plate 501. After the isolation door 503 moves a certain distance, the isolation door 503 will isolate the welding area at the top of the rotating circular plate 14, which can ensure the safety of the operator, prevent arc damage, block spatter, improve the welding quality, stabilize the welding environment, and ensure the stability of the welding arc. The protective mechanism 5 also includes a second sliding column 505, a locking plate 506, and a hook plate 507. The second sliding column 505 is fixedly connected to the inner wall of the fixed plate 408, the locking plate 506 is fixedly connected to the circumferential surface of the second sliding column 505, and the hook plate 507 is fixedly connected to the inner wall of the isolation door 503. The second sliding column 505 is in contact with the support platform 2 and is used to drive the locking plate 506 to move. The roller 504 is in contact with the guide groove plate 501, and the isolation door 503 is in contact with the housing 1 and is used to isolate and protect the welding area from the outside world. When the fixed plate 408 moves, the movement of the fixed plate 408 will drive the sliding column 505 to move, and the movement of the sliding column 505 will drive the locking plate 506 to move. Before the locking plate 506 moves, the isolation door 503 will drive the hook plate 507 to move. After the hook plate 507 moves a certain distance, the hook plate 507 is on the movement trajectory of the locking plate 506. At this time, during the movement, the locking plate 506 will contact the slot of the hook plate 507 and limit the hook plate 507, so that the hook plate 507 cannot move. The hook plate 507 will prevent the isolation door 503 from opening, which can prevent unauthorized personnel from opening the isolation door 503 out of curiosity during the welding of air conditioning copper pipes, causing injury to personnel and improving the safety of the device.

[0024] Overall working principle: The L-plate 402 rotates at an angle, causing the spring sleeve 404 to rotate and move. At this time, the spring sleeve 404 contacts the parts at the interface of the air conditioning copper pipe and clamps and fixes the parts at the interface, improving the stability of the air conditioning copper pipe during welding, enhancing the welding quality and precision, and maintaining stability during the welding process. After moving a certain distance, the semi-arc plate 409 contacts the surface of the lower area of ​​the air conditioning copper pipe. At this time, multiple semi-arc plates 409 apply a uniform clamping force, preventing uneven force on the air conditioning copper pipe during welding, thus avoiding misalignment. Slight displacement and deformation improve the welding efficiency of the device, reduce the generation of welding defects in air conditioning copper pipes, and enhance economic benefits. The isolation door 503 isolates the welding area at the top of the rotating circular plate 14, ensuring the safety of operators, preventing arc damage, blocking spatter, improving welding quality, stabilizing the welding environment, and ensuring the stability of the welding arc. This prevents the hook plate 507 from moving and thus prevents the isolation door 503 from opening, preventing unauthorized personnel from curiously opening the isolation door 503 during the welding of air conditioning copper pipes and causing injury, thereby improving the safety of the device.

[0025] A welding method for a welding apparatus used in processing copper pipe joints for air conditioners includes the following steps: Step 1: When the device is started, the operator first places the air conditioning copper pipe that needs to be welded vertically in the welding area of ​​the support platform 2. At this time, the motor will start, and the output end of the motor will drive the reciprocating screw 3 to rotate. The rotation of the reciprocating screw 3 will drive the pull rod 7 to rotate. Step 2: At this time, the pull rod 7 is limited by the support platform 2. The pull rod 7 will cause the moving plate 6 to move laterally through the reciprocating groove on the surface of the reciprocating screw 3 during the rotation of the reciprocating screw 3. The movement of the moving plate 6 will drive the pull rod 7 to move, the movement of the pull rod 7 will drive the connecting block 8 to move, and the movement of the connecting block 8 will drive its own locking block to move. Step 3: Simultaneously, as the connecting block 8 moves, it will also drive the horizontal plate 10 to move. The movement of the horizontal plate 10 will drive the elastic telescopic rod 11 to move. The movement of the elastic telescopic rod 11 will drive the arc clamp plate 12 to move. During the movement of the connecting block 8, the connecting block 8 will drive its own locking block to move. After the locking block moves a certain distance, the locking block will enter the groove of the vertical slot block 9 and be limited and guided by the vertical slot block 9. At this time, the pulling rod 7 will continue to move. Step 4: During the guiding process of the clamping block, the angle of the pull rod 7 will rotate. The movement of the pull rod 7 will indirectly push the connecting block 8 to rise in the groove of the vertical slot block 9. While the pull rod 7 continues to move, the elastic telescopic rod 11 will drive the arc clamp 12 to contact the surface of the air conditioning copper pipe and clamp the air conditioning copper pipe.

12. A welding method for a welding apparatus for processing copper pipe joints in air conditioning systems, employing the welding apparatus for processing copper pipe joints in air conditioning systems as described in claim 11, characterized in that: Includes the following steps: Step 1: When the device is started, the operator first places the air conditioning copper pipe that needs to be welded vertically in the welding area of ​​the support platform (2). At this time, the motor will start and the output end of the motor will drive the reciprocating screw (3) to rotate. The rotation of the reciprocating screw (3) will drive the pull rod (7) to rotate. Step 2: At this time, the pull rod 1 (7) is limited by the support platform (2). The pull rod 1 (7) will cause the moving plate (6) to move laterally through the reciprocating groove on the surface of the reciprocating screw (3) during the rotation of the reciprocating screw (3).

During the movement of the connecting block (8), the connecting block (8) will drive its own locking block to move. When the locking block moves a certain distance, the locking block will enter the groove of the vertical slot block (9) and be limited and guided by the vertical slot block (9). At this time, the pulling rod (7) will continue to move. Step 4: Pull rod 1 (7) will rotate its angle during the process of being guided by the clamping block. The movement of pull rod 1 (7) will indirectly push the connecting block (8) to rise in the groove of the vertical slot block (9). While pull rod 1 (7) continues to move, the elastic telescopic rod (11) will drive the arc clamp (12) to contact the surface of the air conditioning copper pipe and clamp the air conditioning copper pipe. The air conditioning copper pipe will be subjected to a reaction force at the same time. The movement of the arc clamp (12) can ensure the accuracy of the welding position of the air conditioning copper pipe, and can closely fit the shape of the air conditioning copper pipe to achieve precise position control and improve the welding accuracy of the air conditioning copper pipe interface.
