Description

Technical Field

[0001] This utility model relates to the field of air conditioner aluminum tube processing technology, specifically an air conditioner aluminum tube processing device with oil spraying positioning function. Background Technology

[0002] In the air conditioning and refrigeration industry, heat exchangers (such as condensers and evaporators) are core components, and their performance directly determines the energy efficiency and reliability of the entire unit. These heat exchangers are typically made of aluminum fins and aluminum U-shaped tubes or straight tubes connected by mechanical tube expansion and flaring processes. Among these processes, flaring is a crucial step, which involves forming a flared end at the end of the aluminum tube to mate with another pipe or valve joint, and then securing it with a nut to achieve a sealed connection.

[0003] The basic principle of the flaring process is to use a special conical flaring tool to apply radial and axial forces to the end of the aluminum tube while rotating at high speed, forcing the tube wall material to undergo plastic flow, ultimately forming a flared mouth with precise dimensions and regular shape. This process involves severe material deformation and high-speed friction between the tool and the workpiece. However, some existing processing devices for flaring air conditioning aluminum tubes show longitudinal scratches on the inner surface of the flared section after flaring. This is generally caused by obstruction of sliding between the tube end and the flaring die. Furthermore, after multiple flaring processes, the flatness of the outer surface decreases, making it prone to sliding obstruction at the flaring section. Uneven feed of the flaring die is also a contributing factor to cracking of the flared aluminum tube, reducing the yield of flared aluminum tubes and affecting not only sealing but also assembly difficulties. Therefore, we propose an air conditioning aluminum tube processing device with an oil spray positioning function to solve the above problems. Utility Model Content

[0022] Please see Figures 1-4This utility model provides a technical solution: an air conditioning aluminum tube processing device with oil spraying positioning function, including a processing table 1, an aluminum tube body 2 is provided on the upper side of the processing table 1, a clamping component for fixing the aluminum tube body 2 is provided on the upper side of the processing table 1, a first connecting plate 3 for installation is provided on the upper side of the processing table 1, and a flaring mold 4 for flaring the aluminum tube body 2 is provided on the front surface of the first connecting plate 3. The flaring mold 4 is an existing structure in the art, so it will not be described in detail.

[0023] A first motor 5 for providing power is fixedly connected to the rear surface of the first connecting plate 3. The output shaft of the first motor 5 rotates through the interior of the first connecting plate 3 and is fixedly connected to the flaring mold 4 via a coupling. An atomizing nozzle 6 for spraying lubricating oil into the opening of the aluminum tube body 2 is provided on the front surface of the first connecting plate 3. Two guide grooves 7 for limiting the movement trajectory of the structure are provided on the upper surface of the processing table 1. A positioning component for positioning the flaring mold 4 and the atomizing nozzle 6 is provided inside the front guide groove 7. A drive component for moving the flaring mold 4 and the atomizing nozzle 6 is provided on the upper surface of the processing table 1.

[0024] The positioning assembly includes a transmission screw 16 for transmission. The transmission screw 16 is rotatably connected to the inside of the front guide groove 7. Two guide blocks 12 for connection are slidably connected inside the two guide grooves 7. The two guide blocks 12 located inside the front guide groove 7 are threaded onto the surface of the transmission screw 16. The rotation of the transmission screw 16 can drive the movement of the two front guide blocks 12.

[0025] The upper surfaces of the four guide blocks 12 are fixedly connected to the mounting plates 13 for support. The surface of the mounting plates 13 is provided with limit grooves 14. The lower surface of the first connecting plate 3 is fixedly connected to the limit blocks 15 for connection. The first connecting plate 3 is slidably connected to the inside of the limit grooves 14 through the limit blocks 15. The movement of the guide blocks 12 can drive the mounting plates 13 to move, thereby driving the first connecting plate 3, the flaring mold 4 and the atomizing nozzle 6 to move. When the flaring mold 4 and the aluminum tube body 2 are aligned, the flaring work can be performed with the help of the drive assembly. When the atomizing nozzle 6 and the aluminum tube body 2 are aligned, the end of the aluminum tube body 2 can be lubricated with the help of the drive assembly, thereby improving the efficiency and quality of the subsequent flaring work.

[0026] A second motor 17 for providing power is fixedly connected to the left side surface of the processing table 1. The output shaft of the second motor 17 rotates through the interior of the processing table 1 and is fixedly connected to the transmission screw 16 by means of a coupling. The second motor 17 can be started by an external controller to drive the rotation of the transmission screw 16.

[0027] The drive assembly includes a fixed plate 8 for support, which is fixedly connected to the upper surface of the processing table 1. An electric push rod 9 for providing power is fixedly connected to the rear surface of the fixed plate 8. The telescopic end of the electric push rod 9 slides through the front surface of the fixed plate 8. A rectangular plate 24 for connection is fixedly connected to the telescopic end of the electric push rod 9. The rectangular plate 24 can be moved by starting the electric push rod 9 through an external controller.

[0028] The upper surface of the mounting plate 13 is provided with a second connecting plate 10 for connection. The lower surface of the second connecting plate 10 is also fixedly connected with a limiting block 15 and slidably connected to the inside of the limiting groove 14 by means of the limiting block 15. The rear surface of the second connecting plate 10 is provided with a rectangular groove 11 for cooperating with the rectangular plate 24. The rectangular plate 24 is slidably connected to the inside of the rectangular groove 11. By driving the rectangular plate 24 to move by the electric push rod 9, the second connecting plate 10 and the first connecting plate 3 can be driven to slide on the upper side of the mounting plate 13, thereby realizing the movement of the flared mold 4 and the atomizing nozzle 6.

[0029] Among them, the first motor 5, the second motor 17 and the electric push rod 9 are also equipped with power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail.

[0030] A storage tank 22 for storing lubricating oil is provided on the right side surface of the processing table 1. A hose 23 for conveying lubricating oil is provided on the outside of the storage tank 22 and is connected to the inside. The other end of the hose 23 is fixedly connected to the first connecting plate 3 and is connected to the atomizing nozzle 6. A pump body is also provided in conjunction with the storage tank 22. The hose 23 is connected to the inside of the storage tank 22 through the pump body. The lubricating oil inside the storage tank 22 can be entered into the hose 23 by starting the pump body through the external controller, so that the lubricating oil can be sprayed out from the inside of the atomizing nozzle 6 later.

[0031] The clamping assembly includes two lower clamps 18 for clamping the aluminum tube body 2. Both lower clamps 18 are fixedly connected to the upper surface of the processing table 1. Since the two lower clamps 18 have the same structure, the following description focuses on one lower clamp 18. An upper clamp 19 is provided on the upper side of the lower clamp 18 for cooperating with the lower clamp 18. An adjusting screw 20 for transmission is rotatably connected to the upper surface of the lower clamp 18. The upper clamp 19 is threaded onto the outside of the adjusting screw 20. A guide rod 21 for limiting the movement trajectory of the upper clamp 19 is fixedly connected to the upper surface of the lower clamp 18. The upper clamp 19 is slidably sleeved on the outside of the guide rod 21. The aluminum tube body 2 is located between the lower clamps 18 and the upper clamp 19. The movement of the upper clamp 19 can be adjusted by rotating the adjusting screw 20, thereby achieving the clamping of the aluminum tube body 2 and ensuring the stability of the aluminum tube body 2 during the flaring operation.

[0032] Rubber pads can be provided on the surfaces of the lower clamp 18 and the upper clamp 19 that are close to each other, thereby increasing the friction between the clamps and the aluminum tube body 2 and further improving the stability of clamping. Since this is a conventional technical means in this field, it will not be described in detail.

[0033] Working principle:

[0034] When using this air conditioning aluminum tube processing device with oil spraying positioning function, the operator places the aluminum tube body 2 to be processed between the lower clamp 18 and the upper clamp 19, and then rotates the two adjusting screws 20 respectively. By rotating the adjusting screws 20, the movement of the upper clamp 19 can be adjusted, thereby clamping the aluminum tube body 2 and ensuring the stability of the aluminum tube body 2 when performing the flaring operation.

[0035] Subsequent workers can start the second motor 17 through an external controller to drive the rotation of the transmission screw 16. The rotation of the transmission screw 16 will drive the movement of the two front guide blocks 12. The movement of the guide blocks 12 will drive the installation plate 13 to move, and in turn drive the first connecting plate 3, the flared mold 4 and the atomizing nozzle 6 to move.

[0036] When the atomizing nozzle 6 and the aluminum tube body 2 are aligned, the electric push rod 9 can be activated by the external controller to move the rectangular plate 24. The movement of the rectangular plate 24 by the electric push rod 9 will cause the second connecting plate 10 and the first connecting plate 3 to slide on the upper side of the mounting plate 13, thereby realizing the movement of the atomizing nozzle 6. Subsequently, the atomizing nozzle 6 will extend into the opening of the aluminum tube body 2. Then, the pump body can be activated by the external controller to allow the lubricating oil inside the storage tank 22 to enter the hose 23, so that the lubricating oil can be sprayed from the inside of the atomizing nozzle 6 into the opening of the aluminum tube body 2, thereby improving the efficiency and quality of the subsequent flaring work.

[0037] When the flaring mold 4 and the aluminum tube body 2 are aligned, the electric push rod 9 can be activated by the external controller to move the rectangular plate 24. The movement of the rectangular plate 24 by the electric push rod 9 can cause the second connecting plate 10 and the first connecting plate 3 to slide on the upper side of the mounting plate 13, thereby realizing the movement of the flaring mold 4. Subsequently, the first motor 5 can be activated by the external controller to realize the flaring work of the flaring mold 4 on the aluminum tube body 2.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
