Technical Field

[0001] This utility model relates to the field of heat exchanger piping technology, specifically a heat exchanger piping connection device. Background Technology

[0002] The heat exchanger pipes are installed on the heat exchanger indoor unit to drain the large amount of condensate generated in the heat exchanger to the outside. During the manufacturing process, the copper pipes need to be welded together using a pipe connection device to facilitate subsequent processing and manufacturing, and then assembled and installed inside the heat exchanger.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a heat exchanger pipe connection device, including a base plate 1 for connecting (welding) copper pipes of a heat exchanger pipe. A movable plate 4 is symmetrically arranged on the base plate 1 via a movable component. A sleeve 10 (which can be rotatably connected via a bearing, a mature technology, and will not be elaborated here) is rotatably mounted on the movable plate 4 via a mounting base 9. The movable plate 4 is connected to the sleeve 10 via a rotating component, allowing for easy rotation of the sleeve 10. The sleeve 10 is equipped with a clamping mechanism for easy clamping during copper pipe welding, facilitating clamping, movement, and rotation operations. This allows for subsequent use with a grinding component and welding device 20, enabling grinding and polishing of the weld area before welding to ensure a good connection.

[0023] Please see Figures 1-5To facilitate clamping, moving, and rotating the two copper tubes to be connected, and to aid in subsequent grinding, polishing, and welding operations, linear guide rail devices 2 with moving components are symmetrically mounted on the base plate 1. A guide rail slider 3 (which can be driven by a linear motor for reciprocating sliding, or by other devices such as a reciprocating lead screw—a mature technology not described in detail here) slides 3 on the linear guide rail device 2. The guide rail slider 3 is fixedly connected to the moving plate 4 with screws. A fixed base 13 with rotating components is welded onto the moving plate 4. A motor 12 is installed inside the fixed base 13, and the output end of the motor 12 is fixedly mounted via a coupling. The sleeve 10 is equipped with a gear 11, and a gear ring 14 that meshes with the gear 11 is fixed on the outside of the sleeve 10, which can easily rotate the sleeve 10 in the mounting base 9. In order to facilitate the clamping and fixing of the copper tube and guide it, a guide post 15 (with a through hole in the middle for easy insertion and guidance of the copper tube) is bonded inside the sleeve 10. The two sleeves 10 are equidistantly connected to each other at their circumferential sides by threaded adjusting bolts 16 of the clamping mechanism. The adjusting bolts 16 pass through the sleeve 10 and extend into the interior where a clamping plate 17 is rotatably provided. A rubber pad 18 is bonded to the inner arc surface of the clamping plate 17 to facilitate the clamping and fixing of the copper tube and facilitate subsequent grinding and welding operations.

[0024] Please see Figures 1-5 To facilitate grinding and polishing the weld joint of the two copper pipes, removing burrs and other impurities to avoid affecting subsequent welding, and to facilitate welding operations and connecting the copper pipes, electric push rods 5 with adjustment mechanisms are vertically mounted at equal intervals on the base plate 1. A fixing block 6 is fixedly mounted on the output end of the electric push rod 5. A linear guide device 2 7 is installed between the two fixing blocks 6 at the same end. A guide slider 2 8 (with the same structure as linear guide device 1 2, not described in detail here) slides on the linear guide device 2 7. The two guide sliders 2 8 are fixedly connected to the horizontal plate 19 by screws. A welding device 20 (only a partial illustration in the figure shows the welding head; it mainly includes a welding machine, gas cylinder, and power supply) is installed on the horizontal plate 19. The device includes a wire feeding mechanism, which facilitates welding of copper tubes. It can also be used for other welding equipment. This is a relatively mature technology and will not be described in detail here. A connecting plate 21 with a grinding component is welded under the horizontal plate 19. A grinding block 22 can be installed under the connecting plate 21 (it can be installed and fixed by means of snap-fit, and is detachable for easy replacement and to ensure the grinding and polishing effect). The grinding block 22 can easily grind and polish the weld joint of the two copper tubes to remove burrs or impurities, ensuring the subsequent welding effect. The corresponding base plate 1 is also equipped with a collection device (not shown in the figure, which can be composed of a collection cover, connecting pipe and collection box, etc.) to facilitate the collection of debris during the grinding process. This is a relatively mature technology and will not be described in detail here.

[0025] Working Principle: In use, the two copper tubes to be welded are inserted into the guide post 15 of the sleeve 10. Then, by rotating the adjusting bolt 16 clockwise, the clamping plates 17 move closer together, and the rubber pad 18 clamps and fixes the copper tubes. The electric push rod 5 retracts, moving the fixing block 6 downwards. At this point, the grinding block 22 is positioned between the two copper tubes. Then, the linear guide rail device 2 moves the guide rail slider 3 upwards, and the two moving plates 4 move closer together, bringing the welding point of the copper tubes into contact with the grinding block 22. The motor 12 rotates the gear 11, which, in conjunction with the gear ring 14, rotates the sleeve 10 within the mounting base 9, thus rotating both copper tubes and allowing the grinding block 22 to clean the welding point. Grinding and polishing are performed to ensure cleanliness and smoothness, facilitating subsequent welding operations. After grinding, the linear guide device 12 operates, moving the moving plates 4 away from each other. Then, the linear guide device 27 operates, moving the guide slider 28, thereby moving the welding device 20 on the horizontal plate 19 to the upper part between the two copper tubes. Then, the linear guide device 12 operates, moving the two moving plates 4 closer together, so that the welding joint of the two copper tubes contacts. The welding device 20 operates, and at the same time, the motor 12 operates, rotating the copper tube inside the sleeve 10 to perform the welding operation. After welding, when it is necessary to remove the tube, the adjusting bolt 16 can be turned counterclockwise to move the clamping plates 17 away from each other, losing their clamping fixation, and the connected copper tube can be pulled out.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
