Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding robot device for finned heat exchangers. Background Technology

[0002] With the development and maturity of welding robots, welding operations between U-shaped bends and straight pipes in existing finned heat exchangers are generally replaced by welding robots instead of manual welding. However, before welding, most of the time it is necessary to manually insert and assemble the U-shaped bends onto the inner wall of the straight pipe. The method of aligning by visual inspection results in low docking efficiency. There is no guiding structure to help manual docking of the bends onto the inner wall of the straight pipe. Therefore, it is necessary to design a finned heat exchanger welding robot device with a guiding structure to improve the docking efficiency and accuracy between the bends and straight pipes. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, which relies on manual visual inspection for alignment, resulting in low efficiency in connecting bent and straight pipes, and lack of a guiding structure to help manual connection of bent pipes to the inner wall of straight pipes quickly, one of the objectives of this utility model is to provide a finned heat exchanger welding robot device.

[0004] One of the objectives of this utility model is achieved by the following technical solution: a finned heat exchanger welding robot device, comprising a base: a limiting component is provided on the upper surface of the base, a finned heat exchanger is placed above the base, a guide component is provided on one side of the upper surface of the base, and a welding robot body is provided on the side of the base away from the guide component; the guide component consists of a fixed frame fixed to one side wall of the base, a support plate symmetrically fixed to one side of the fixed frame, an adjusting plate symmetrically and movably connected to one side of the support plate, a semi-circular guide sleeve equidistantly fixed to one side of the adjusting plate, an adjusting rod fixed to the upper center of the adjusting plate, and an abutment block fixed to one side wall of the support plate, wherein the adjusting rod movably passes through the support plate, and a bent pipe is placed on the inner wall of the semi-circular guide sleeve. By setting up limiting components and guiding components, the limiting components can firmly limit and fix the finned heat exchanger on the base, thereby preventing the position of the finned heat exchanger from shifting and effectively improving the welding stability of the finned heat exchanger. The guiding components can enable the bent tube to be quickly inserted into the inner wall of the straight tube of the finned heat exchanger without the need for manual visual alignment, effectively improving the docking efficiency and docking accuracy.

[0005] According to the aforementioned finned heat exchanger welding robot device, a knob is fixedly provided on the upper surface of the adjusting rod for easy rotation of the adjusting rod.

[0006] According to the aforementioned finned heat exchanger welding robot device, the limiting assembly comprises an abutment plate fixed to one side of the base, a slide groove fixed to one side of the base, a slider slidably connected to the inner wall of the slide groove, a limiting plate fixed to one side of the slider, a through hole formed in the middle of the slider, and a limiting rod threadedly connected to the inner wall of the slide groove. This facilitates the stable limiting and fixing of the finned heat exchanger on the base, preventing its position from shifting and affecting the welding quality.

[0007] According to the aforementioned finned heat exchanger welding robot device, the diameter of the limiting rod is adapted to the inner diameter of the through hole, and a knob is fixedly provided on the upper surface of the limiting rod to facilitate rotation of the limiting rod.

[0008] According to the aforementioned finned heat exchanger welding robot device, the centerline of the semi-circular guide sleeve and the centerline of the straight tube of the finned heat exchanger are on the same straight line. The diameter of the bent tube is adapted to the inner diameter of the straight tube of the finned heat exchanger, and the bent tube is inserted into the inner wall of the straight tube of the finned heat exchanger. This improves the docking accuracy.

[0009] According to the aforementioned finned heat exchanger welding robot device, a groove is formed on the front surface of the base, and a storage drawer is slidably connected to the inner wall of the groove. Dividers are fixedly arranged at equal intervals inside the storage drawer. This facilitates the storage of multiple bent pipes to prevent loss and makes it easy to retrieve and use the bent pipes.

[0010] According to the aforementioned finned heat exchanger welding robot device, a pull handle is rotatably connected to the center of the front surface of the storage drawer. This facilitates pulling out the storage drawer.

[0011] According to the aforementioned finned heat exchanger welding robot device, an anti-slip pad is fixedly connected to the lower surface of the base to prevent slipping.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] 1. By setting up limiting components and guiding components, compared with the existing technology, this device can limit and fix the finned heat exchanger on the base through the limiting components, thereby preventing its position from shifting and improving the welding stability of the finned heat exchanger. Furthermore, the guiding components can enable the quick insertion of the bent tube into the inner wall of the straight tube of the finned heat exchanger without the need for manual alignment, effectively improving the docking efficiency and accuracy, and thus enhancing the convenience and practicality of the device.

[0014] 2. With the setting of limiting components, guiding components and storage drawers, and in cooperation with the welding robot body, when the welding robot body is welding multiple bends that have been installed on the inner wall of the straight pipe section on one side, the guiding components can quickly connect the multiple bends to the inner wall of the straight pipe section on the other side, thereby effectively improving work efficiency. In addition, the storage drawers can store multiple bends inside, thereby avoiding the loss of bends and making it easy to retrieve bends, which is convenient to use.

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-7 A finned heat exchanger welding robot device includes a base 1. A limiting component 2 is provided on the upper surface of the base 1. A finned heat exchanger 3 is placed on top of the base 1. A guide component 4 is provided on one side of the upper surface of the base 1. A welding robot body 5 is provided on the side of the base 1 away from the guide component 4. The guide component 4 consists of a fixed frame 41 fixed to one side wall of the base 1, a support plate 42 symmetrically fixed to one side of the fixed frame 41, an adjusting plate 43 symmetrically and movably connected to one side of the support plate 42, a semi-circular guide sleeve 44 equidistantly fixed to one side of the adjusting plate 43, an adjusting rod 45 fixed to the upper center of the adjusting plate 43, and an abutment block 46 fixed to one side wall of the support plate 42. The adjusting rod 45 movably passes through the support plate 42. A bent pipe 6 is placed on the inner wall of the semi-circular guide sleeve 44. A knob 7 is fixed on the upper surface of the adjusting rod 45. The limiting component 2 consists of the abutment plate 21 fixed to one side of the upper part of the base 1. The base 1 is composed of a slide groove 22 fixed on one side above the base 1, a slider 23 slidably connected to the inner wall of the slide groove 22, a limiting plate 24 fixed on one side of the slider 23, a through hole 25 opened in the middle of the slider 23, and a limiting rod 26 threadedly connected to the inner wall of the slide groove 22. The diameter of the limiting rod 26 is adapted to the inner diameter of the through hole 25. A knob 28 is fixed on the upper surface of the limiting rod 26. The center line of the semi-circular guide sleeve 44 and the center line of the straight tube of the finned heat exchanger 3 are on the same straight line. The diameter of the bent tube 6 is adapted to the inner diameter of the straight tube of the finned heat exchanger 3. The bent tube 6 is inserted into the inner wall of the straight tube of the finned heat exchanger 3. A groove 9 is opened on the front surface of the base 1. A storage drawer 10 is slidably connected to the inner wall of the groove 9. Dividers 11 are fixedly fixed at equal intervals inside the storage drawer 10. A handle 12 is rotatably connected to the middle of the front surface of the storage drawer 10. An anti-slip pad 13 is fixedly connected to the lower surface of the base 1.

[0028] With the setting of limiting component 2 and guiding component 4, the limiting component 2 can firmly limit and fix the finned heat exchanger 3 on the base 1, thereby preventing the position of the finned heat exchanger 3 from shifting, effectively improving the welding stability of the finned heat exchanger 3. The guiding component 4 can realize the quick insertion of the bent tube 6 into the inner wall of the straight tube of the finned heat exchanger 3 without the need for manual visual alignment, effectively improving the docking efficiency and docking accuracy. In addition, the storage drawer 10 can store multiple bent tubes 6 inside, making it convenient to take out the bent tubes 6 for docking and avoiding the loss of the bent tubes 6, making it convenient to use.

[0029] Working principle: When it is necessary to connect and weld the bent pipe 6 to the straight pipe part of the finned heat exchanger 3, first place the finned heat exchanger 3 on the base 1 and make one side of it abut against the side wall of the slide groove 22, and at the same time make the side near the guide component 4 abut against the abutment plate 21. Then, turn the knob 28 to drive the limiting rod 26 to rotate upward and no longer abut against the inner wall of the slide groove 22, thereby unlocking the slider 23. Push the slider 23 to move it towards the side of the finned heat exchanger 3 on the inner wall of the slide groove 22, thereby driving the limiting plate 24 to move and abut against the side wall of the finned heat exchanger 3. Then, screw the limiting rod 26 into the inner wall of the slide groove 22 and through the through hole 25 to limit the position of the slider 23. Thus, the finned heat exchanger 3 is limited and fixed on the base 1 by the limiting plate 24 and the abutment plate 21.

[0030] After the position of the finned heat exchanger 3 is determined, the bent tube 6 is placed inside the two semi-circular guide sleeves 44 and pushed towards the straight tube of the finned heat exchanger 3. Since the semi-circular guide sleeves 44 are concentric and aligned with the straight tube of the finned heat exchanger 3, the bent tube 6 can be smoothly inserted into the inner wall of the straight tube. The guide assembly 4 allows for easy insertion of the bent tube 6 into the inner wall of the straight tube without the need for manual alignment, improving both the accuracy and efficiency of the connection. When welding is required between the bent tube 6 and the straight tube, the position of the finned heat exchanger 3 is unlocked using the limiting assembly 2, and then the knob 7 is turned to rotate the adjusting rod 45. The support plate 42 is moved so that the two semi-circular guide sleeves 44 no longer abut against the bend 6, thus no longer limiting the position of the bend 6. Then, the finned heat exchanger 3 and the bend 6 are moved to the side facing the welding robot body 5, and the straight pipe part on the other side of the finned heat exchanger 3 is oriented towards the guide component 4 by the limiting component 2. Thus, the welding robot body 5 welds the connection between the bend 6 and the straight pipe part. At the same time, multiple bends 6 are installed on the inner wall of the straight pipe part on the other side by the guide component 4, thereby effectively improving the docking efficiency of the bend 6 and the straight pipe part and the welding efficiency at the connection between the two, and effectively improving the practicality and convenience of the device.
