Detailed Implementation

[0018] Example 1

[0019] like Figures 1 to 4 As shown, the present invention proposes a finned tube assembly welding device, including a welding frame 1, a steel pipe placement mechanism, and a steel plate placement mechanism. The steel pipe placement mechanism consists of multiple sets of movable boxes 203 evenly installed on the welding frame 1, sockets 205 installed on the movable boxes 203, a drive assembly disposed inside the sockets 205, and multiple sets of abutment seats 303. The multiple sets of abutment seats 303 are evenly distributed on the sockets 205, and the multiple sets of abutment seats 303 are driven by the drive assembly to slide closer to or further away from the center position of the sockets 205. The steel plate placement mechanism consists of a movable seat 4, a movable frame 401, and multiple sets of clamping assemblies symmetrically installed on the movable seat 4 and the movable frame 401. The movable seat 4 is driven by an electric push rod to slide and adjust along the horizontal direction of the welding frame 1. The movable frame 401 is connected to the movable seat 4 by an electric push rod, and the bottom end of the movable frame 401 is slidably connected to the welding frame 1.

[0020] Furthermore, the drive assembly includes a first threaded rod 3 and a tapered seat 301; the first threaded rod 3 is driven to rotate by a motor installed inside the movable box 203, and the other end of the first threaded rod 3 extends into the socket 205 and is rotatably connected to the other end of the socket 205; the tapered seat 301 is threadedly sleeved on the outside of the first threaded rod 3, and multiple sets of tapered seats 301 are provided. A slider is provided on the tapered seat 301, and a groove is provided on the inner wall of the socket 205. The slider slides into the groove, which facilitates the guidance of the tapered seat 301 so that it can only slide and adjust along the horizontal direction of the socket 205.

[0021] Furthermore, the abutment 303 is arc-shaped, and a connecting rod 302 is installed on the abutment 303 at one end near the socket 205. The connecting rod 302 is slidably connected to the socket 205. The other end of the connecting rod 302 extends into the socket 205 and is equipped with a first spring 304. The other end of the first spring 304 is connected to the inner wall of the socket 205. The end of the connecting rod 302 away from the abutment 303 corresponds to the conical seat 301.

[0022] Furthermore, the clamping assembly includes a U-shaped base 5, a pull rod 501, and a second spring 502; the U-shaped base 5 is mounted on the movable base 4 or the movable frame 401; the pull rod 501 is slidably inserted into the U-shaped base 5, and the bottom end of the pull rod 501 extends into the interior of the U-shaped base 5 and is fitted with an abutment plate 503, which abuts against the bottom end of the U-shaped base 5; the second spring 502 is sleeved on the outside of the pull rod 501, the top end of the second spring 502 is connected to the top end of the pull rod 501, and the bottom end of the second spring 502 is connected to the top end of the U-shaped base 5.

[0023] Furthermore, two sets of robotic arm mounting seats 6 are symmetrically arranged on the welding frame 1. The robotic arm mounting seats 6 are provided with multiple sets of mounting holes. The robotic arm mounting seats 6 are connected to the welding frame 1 through a horizontal moving mechanism. The robotic arm mounting seats 6 are used to install multiple sets of welding robotic arms and welding equipment. The two sets of robotic arm mounting seats 6 are distributed above and below the steel pipe. The horizontal moving mechanism is existing technology and can be composed of a second threaded rod and a crossbar. The second threaded rod is driven by a motor to rotate and connect to the welding frame 1. The crossbar is symmetrically arranged with the second threaded rod. One end of the robotic arm mounting seat 6 is threadedly connected to the second threaded rod, and the other end is slidably connected to the crossbar.

[0024] In this embodiment, the steel pipe is inserted into the outside of the socket 205 until the end of the steel pipe abuts against the movable box 203. The controller starts the motor to drive the first threaded rod 3 to rotate, causing multiple sets of conical seats 301 to slide horizontally along the first threaded rod 3, thereby pushing the corresponding connecting rod 302, compressing the first spring 304, and then the connecting rod 302 drives the abutment seat 303 to move away from the socket 205, thereby pressing the inner wall of the steel pipe tightly with multiple sets of abutment seats 303, thus quickly clamping and limiting the steel pipe; the pull rod 501 is moved upward along the U-shaped seat 5 to... The second spring 502 is compressed, which in turn moves the abutment plate 503 upward away from the bottom end of the U-shaped seat 5. One end of the steel plate is inserted between the abutment plate 503 and the bottom end of the U-shaped seat 5, and the end of the steel plate abuts against the U-shaped seat 5. The pull rod 501 is released, and under the restoring force of the second spring 502, the abutment plate 503 is moved to press the steel plate against the U-shaped seat 5. At this time, one end of the steel plate is clamped on the movable seat 4. It should be noted that the width of the steel plate is greater than the width of the U-shaped seat 5 and the abutment plate 503, and the clamping assembly is clamped in the middle position of the end of the steel plate, which facilitates the clamping of both ends of the steel plate. The edge to be welded is exposed. Then, the electric push rod drives the moving frame 401 towards the moving seat 4 for adjustment until the clamping assembly on the moving frame 401 can clamp the other end of the steel plate, thus limiting the steel plate. The electric push rod drives the moving seat 4 to move the steel plate towards multiple sets of steel pipes until the steel plate moves between two adjacent sets of steel pipes. At this point, the welding edges on both sides of the steel plate abut against the corresponding steel pipes. Multiple welding robotic arms and welders are pre-installed on the robotic arm mounting base 6, allowing welding of the welding ends of multiple sets of steel pipes and steel plates. After welding is completed, the robotic arm... The mounting base 6 is moved to the edge, and the steel pipe placement mechanism is adjusted so that the multiple sets of abutment seats 303 move toward the socket 205 and no longer abut against the inner wall of the steel pipe. The welded steel pipe and steel plate can then be separated from the steel pipe placement mechanism. Then, the moving frame 401 is moved away from the moving base 4 by the electric push rod, and the end of the steel plate can be disengaged from the clamping mechanism. The welded steel pipe and steel plate can be taken out from the steel plate placement mechanism. The cutting mechanism can then be used to cut the steel plate between the two sets of steel pipes from the middle. After the cutting, steel plates are welded on both sides of the steel pipe, thus completing the finned tube splicing and welding work.

[0025] Example 2

[0026] like Figures 1 to 3As shown, the finned tube assembly welding device proposed in this utility model, compared with Embodiment 1, further includes an adjustment component in the steel pipe placement mechanism. The adjustment component includes a slide block 2, an adjustment channel 201, and a guide rod 202. The slide block 2 is driven by a lifting component to slide and adjust along the height direction of the welding frame 1. The lifting component is an electric push rod. A guide groove is provided on the side wall of the welding frame 1 to slide and connect with the slide block 2, thereby improving the sliding stability of the slide block 2. Multiple sets of adjustment channels 201 are provided, and the multiple sets of adjustment channels 201 are evenly distributed on the slide block 2. Guide rod 202 is installed on welding frame 1. Multiple sets of movable boxes 203 are slidably sleeved on guide rod 202. A slide rod 204 is installed on the end of movable box 203 away from socket 205. The other end of slide rod 204 passes through the corresponding adjustment channel 201 and is equipped with a slider. The slider is slidably connected to slide seat 2. An auxiliary rod is also provided on welding frame 1. The auxiliary rod is located below guide rod 202. A connecting plate is provided at the bottom of movable box 203. The bottom end of the connecting plate is slidably connected to the auxiliary rod to improve the sliding stability of movable box 203.

[0027] In this embodiment, the sliding block 2 is driven to move up the height direction of the welding frame 1 by the lifting component. Under the guidance of multiple sets of adjustment channels 201, the multiple sets of sliding rods 204 are dispersed from each other, thereby driving the corresponding moving boxes 203 to move away from each other at equal distances along the guide rod 202. Conversely, when the sliding block 2 moves down the height direction of the welding frame 1, the multiple sets of moving boxes 203 move closer to each other at equal distances along the guide rod 202. The distance between the multiple sets of sockets 205 can be adjusted by the adjustment component, which can adapt to welding steel pipes of different diameters or steel plates of different widths, and has a wider range of applications.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
