Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning heat exchanger equipment, specifically an automatic pipe-threading device for air conditioning heat exchangers. Background Technology

[0002] As is well known, the cooling system used in air conditioning equipment includes a compressor, a refrigerant condensing heat exchanger, a refrigerant expansion device, and a refrigerant evaporating heat exchanger. These components are sequentially connected to each other via refrigerant pipes to form a refrigerant circuit. When the compressor starts in the refrigerant circuit, the refrigerant circulates through the refrigerant pipes and transfers or absorbs heat from the environment to continuously change its state. This cooling system enables the cooling of indoor air. A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. It consists of components such as a shell, heat transfer tube bundle, tube sheet, baffles, and tube box. It is generally used for air conditioning heat exchange. In the heat exchanger production process, heat transfer tubes and connecting tubes are manufactured on different machines. In order to reduce the volume and maximize heat conversion, heat transfer tubes usually need to be bent into various different structures. Therefore, connecting tubes are needed for connection. However, the volume of heat transfer tubes is relatively small, and fully automated connection equipment is expensive. As a result, this process in the factory is still mainly done manually. The tubes are arranged and the connecting tubes are manually connected to the heat transfer tubes one by one. This method is not only labor-intensive but also inefficient, and it is difficult to meet the needs of today's large-scale production.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3 As shown: An automatic pipe threading device for an air conditioner heat exchanger includes a heat pipe support platform 1, circular grooves 2, and a partition plate 3. Circular grooves 2 are evenly spaced at the center of the heat pipe support platform 1. A pipe threading assembly and a gripping assembly are respectively provided at both ends of the heat pipe support platform 1. The pipe threading assembly includes a slide rail 5, a moving plate 6, and a first cylinder 7. The gripping assembly includes a displacement plate 8, a clamping head 10, a half-gear 15, and a connecting block 14. There are two slide rails 5, which are parallel to each other on the heat pipe support platform 1. The moving plate 6 is slidably connected to the slide rails 5. The pipe to be threaded is placed in the circular groove 2, and then another pipe to be threaded is inserted one by one into the circular grooves on the moving plate 6. Then, driven by the first cylinder 7, the moving plate 6 moves forward as a whole, thereby completing the threading of the two pipes. After the threading is completed, the moving plate... With the front of cylinder 6 pushed down, one end of the pipe is pushed out of the circular groove 2. At this time, with the activation of the second cylinder 16, the displacement plate 8 moves forward as a whole, and then the handle 9 is pushed forward, which drives the connecting column 12 to move forward. At this time, the rotating rod 13 rotates counterclockwise with its connection point with the connecting column 12 as the center, which in turn pushes the connecting block 14 to rotate counterclockwise, causing the half gear 15 to rotate upward. The clamping head 10 that meshes with it is driven to move upward, causing the two clamping heads 10 to expand. Then, the circular pipe is aligned with the middle of the two clamping heads 10, and the handle 9 is pulled backward. The connecting column 12 moves backward, and the rotating rod 13 rotates clockwise with its connection point with the connecting column 12 as the center, which pushes the connecting block 14 to rotate clockwise. The two clamping heads 10 tighten and clamp the pipe. Then, the displacement plate 8 is pulled outward to pull out the pipe and complete the collection.

[0018] The movable plate 6 is fixed with a downwardly extending surface, and the output end of the first cylinder 7 is connected to the extending surface. The movable plate 6 has a circular slot, the radius of which is smaller than the radius of the pipe inlet 4. The heat pipe support platform 1 is provided with a partition 3, and the partition 3 has pipe inlets 4 at equal intervals. The position of each pipe inlet 4 corresponds to the position of a circular slot 2. The pipe is limited by the circular slot 2 and the pipe inlet 4 on the partition 3. The circular slot fixes the pipe to be piped. The pipe is moved by the movement of the movable plate 6 to complete the pipe insertion.

[0019] The movable plate 6 has multiple equally spaced circular slots, and the positions of the multiple circular slots correspond one-to-one with the positions of the pipe openings 4, which facilitates pipe insertion.

[0020] The other end of the heat pipe support platform 1 is provided with a displacement plate 8, the output end of the second cylinder 16 is connected to the displacement plate 8, and a handle 9 is provided on one side of the displacement plate 8. A fixing post 11 is fixedly connected to the handle 9. While one end completes the pipe insertion, the other end is used for picking up.

[0021] A connecting column 12 is fixedly connected to the inner side of the fixed column 11. The connecting column 12 passes through the displacement plate 8 and the upper and lower ends of the displacement plate 8 are rotatably connected to the rotating rods 13. The other ends of the two rotating rods 13 are rotatably connected to the connecting blocks 14. When the connecting column 12 moves forward or backward, it drives the rotating rods 13 to rotate clockwise or counterclockwise, thereby driving the connecting blocks 14 to move forward and backward, ultimately realizing the clockwise and counterclockwise rotation of the half gear 15 and controlling the opening and closing of the two clamping heads 10. The connecting block 14 is located inside the displacement plate 8, and the innermost side of the clamping head 10 is also located inside the displacement plate 8.

[0022] A half gear 15 is fixedly connected to the upper end of the connecting block 14. The teeth of the half gear 15 mesh with the tooth groove on the inner side of the clamping head 10. A vertical groove is opened on the side of the displacement plate 8 facing the clamping head 10, so that the two clamping heads 10 can move up and down and open respectively. The inner wall of the clamping head 10 is provided with grooves to better grip the pipe.

[0023] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
