Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, and in particular to an automated welding equipment. Background Technology
[0002] Straight seam welding is a common welding process. After rolling sheet metal into tubes or cylinders, or after joining two sheet metal pieces together, welding can be completed along a straight seam. It is mainly used in pipe and cylinder processing and steel plate splicing.
[0003] Straight seam welding can be performed manually or automatically. For example, the Chinese utility model patent CN215999173U discloses a straight seam welding machine for ventilation ducts. This machine includes a welding machine base, primarily used as a support structure for the welding machine. The base has an L-shaped structure, with support beams fixedly installed on its top. These support beams are arranged symmetrically about the vertical center line of the base in two sets. The rear ends of the support beams are fixedly connected to the front outer wall of the base. This existing solution can weld straight seams formed by rolling in ventilation ducts, thus replacing manual labor and enabling automated welding. Welding is required. Therefore, in this application, the pipe is fixed by pressing the pipe between the upward-moving push rod and the support beam. However, in this process, the pipe is made of cut and rolled sheet metal. At the same time, the two adjacent ends of the pipe are not limited. After being fitted onto the outside of the push rod, the connection point faces upward due to the welding requirements. Therefore, the gap and position of the weld are uncontrollable due to the pipe's own weight and deflection on the outside of the push rod. Therefore, according to the existing welding solutions, it is necessary to manually align the two adjacent ends of the pipe twice, which makes it impossible to achieve efficient pipe welding.
[0004] In view of the problems existing in the above-mentioned existing technologies, it is necessary to research and design a new type of automated welding equipment to overcome the problems existing in the existing technologies. Utility Model Content
[0005] To address the technical problem of existing technologies requiring two manual alignment processes, which hinders efficient welding, this invention provides an automated welding device. This device primarily utilizes an inner positioning shaft in conjunction with an outer clamp and positioning plate to achieve pipe positioning and fixation. Combined with an alignment block for automatic seam alignment, it effectively solves the problems described in the prior art.
[0006] The technical means adopted in this utility model are as follows:
[0007] An automated welding device includes a worktable; a main controller is mounted on one side of the upper end of the worktable, and a support is mounted on the other side; a counter-sliding mechanism is fixedly mounted on the upper end of the worktable near the main controller; two outer sleeves are symmetrically fixedly connected to the counter-sliding mechanism; a shaft seat is fixedly connected to the support; a mounting shaft is fixedly connected to one side of the shaft seat; an inner positioning shaft is fixedly fitted to the outer side of the mounting shaft; an X-axis slide is fixedly connected to the upper end of the worktable at a position behind the counter-sliding mechanism; a first carrier plate is fixedly connected to the front side of the X-axis slide; a welding torch mechanism is fixedly connected to the front side of the first carrier plate; a second carrier plate is fixedly connected between the welding torch mechanism and the first carrier plate; a first cylinder is fixedly connected to the second carrier plate; the output end of the first cylinder extends downward to below the second carrier plate and is fixedly connected to a positioning plate.
[0008] Furthermore, the opposing sliding mechanism includes: a mounting platform fixedly connected to the workbench; a second cylinder fixedly connected to the mounting platform; the second cylinder being connected to an external air pump via an air pipe to provide power for the horizontal movement of the slide plates; a rotating shaft rotatably connected to the mounting platform adjacent to the second cylinder; and a gear fixedly connected to the rotating shaft to provide a connection condition for the transmission of the two slide plates.
[0009] Furthermore, multiple parallel guide rails are fixedly connected to the mounting platform; two slide plates are slidably connected to the multiple guide rails via sliders; the two slide plates are fixedly connected to each other to form a whole; one of the slide plates is fixedly connected to the output end of the second cylinder to provide an installation foundation and movement conditions for the outer sleeve.
[0010] Furthermore, two parallel insertion channels are provided at the lower end of the slide plate; a base plate is fixedly connected to the insertion channels of the two opposing slide plates; a toothed rail is fixedly connected to the lower end of the base plate; the two toothed rails are arranged opposite each other and are respectively meshed with gears; when the two slide plates move relative to each other on multiple guide rails, the base plate of one slide plate can be fitted into the insertion channel of the other slide plate to prevent interference in the translation of the two slide plates. At the same time, the two toothed rails are respectively meshed with gears, so that relative movement can be achieved under the control of the second cylinder to achieve a surrounding clamping of the pipe.
[0011] Furthermore, the outer sleeve is fixedly connected to the corresponding slide plate; a groove is provided on one side of the outer sleeve; a flushing calibration block is fixedly connected in the groove; a slope is provided on one side of the flushing calibration block; when the two outer sleeves move relative to each other through the bearing and cooperate with the inner positioning shaft to clamp and align the pipe, the two flushing calibration blocks can be used in conjunction with the bearing to align the two ends of the pipe.
[0012] Furthermore, a positioning groove is provided at the upper end of the inner positioning shaft, and inner positioning shafts of different diameters can be replaced on the outside of the mounting shaft according to different pipe diameters to provide internal support for the pipe.
[0013] Furthermore, the positioning plate is located directly above the positioning groove; two guide shafts are also symmetrically fixedly connected to the positioning plate, and the upper ends of the two guide shafts are respectively inserted into the second carrier plate. After the lower end of the positioning plate is controlled by the first cylinder to abut against the positioning groove, it can prevent the pipe from rotating arbitrarily outside the inner positioning shaft, thus realizing the seam alignment operation.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] The automated welding equipment provided by this utility model uses an opposing sliding mechanism to drive the outer sleeve to achieve a surrounding clamping of the pipe. Combined with the internal support of the inner positioning shaft and the positioning plate to restrict the rotation of the pipe, it can quickly fix the pipe and ensure the straightness of the weld joint. In addition, the alignment block on the outer sleeve can automatically complete the alignment of the pipe end face, which can greatly improve the processing accuracy and operation efficiency of straight seam welding.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0026] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0027] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description.

[0030] like Figures 1-5 As shown, the present invention provides an automated welding device, including a workbench 1, a main controller 2 fixedly connected to the workbench 1, a counter-sliding mechanism 3 fixedly connected to the workbench 1 adjacent to the main controller 2, two outer sleeves 4 symmetrically fixedly connected to the counter-sliding mechanism 3, a bearing seat 5 fixedly connected to the side of the workbench 1 away from the main controller 2 via a bracket 6, a mounting shaft 7 fixedly connected to one side of the bearing seat 5, an inner positioning shaft 8 fixedly connected to the outside of the mounting shaft 7, an X-axis slide 9 fixedly connected to the workbench 1 located behind the counter-sliding mechanism 3, a first carrier plate 10 fixedly connected to the front of the X-axis slide 9, a welding gun mechanism 11 fixedly connected to the front of the first carrier plate 10, a second carrier plate 12 fixedly connected between the welding gun mechanism 11 and the first carrier plate 10, a first cylinder 13 fixedly connected to the second carrier plate 12, and a positioning plate 14 fixedly connected to the output end of the first cylinder 13 extending downward to below the second carrier plate 12.
[0031] like Figures 1-3 As shown, the opposing sliding mechanism 3 includes a mounting platform 15 fixedly connected to the worktable 1. A second cylinder 17 is fixedly connected to the mounting platform 15. The second cylinder 17 is connected to an external air pump via an air pipe and is used to provide power for the horizontal movement of the slide plate 20. A rotating shaft 18 is rotatably connected to the mounting platform 15 adjacent to the second cylinder 17. A gear 19 is fixedly connected to the rotating shaft 18 to provide the connection conditions for the transmission of the two slide plates 20. Multiple guide rails 16 are fixedly connected to the mounting platform 15, and two slide plates 20 are slidably connected to the multiple guide rails 16 via sliders. One of the guide rails 16 is fixedly connected to the output end of the second cylinder 17 to provide power for the outer clamp 4. To provide a foundation for installation and movement, the lower end of the slide plate 20 is provided with an insertion channel 21. A base plate 22 is fixedly connected to one side of the slide plate 20 near the insertion channel 21. A toothed rail 23 is fixedly connected to the lower end of the base plate 22. The two toothed rails 23 are arranged opposite to each other and are respectively engaged with the gear 19. When the two slide plates 20 move relative to each other on multiple guide rails 16, the base plate 22 of one slide plate 20 can be fitted into the insertion channel 21 of the other slide plate 20 to prevent interference during the translation of the two slide plates 20. At the same time, the two toothed rails 23 are respectively engaged with the gear 19, so that relative movement can be achieved under the control of the second cylinder 17 to achieve a surrounding clamping of the pipe.
[0032] like Figure 1 , Figure 5 As shown, the outer sleeve 4 is fixedly connected to the corresponding slide plate 20. A groove 24 is provided on one side of the outer sleeve 4. A flushing calibration block 25 is fixedly connected in the groove 24. A slope is provided on one side of the flushing calibration block 25. When the two outer sleeves 4 move relative to each other through the bearing 5 and cooperate with the inner positioning shaft 8 to clamp and align the pipe, the two flushing calibration blocks 25 can be used in conjunction with the bearing 5 to align the two ends of the pipe.
[0033] like Figure 4 As shown, the upper end of the inner positioning shaft 8 is provided with a positioning groove 26, and different diameter inner positioning shafts 8 can be replaced on the outside of the mounting shaft 7 according to different pipe diameters to provide internal support for the pipe.
[0034] like Figure 1 , Figure 5 As shown, the positioning plate 14 is located directly above the positioning groove 26, and two guide shafts are symmetrically fixedly connected to the positioning plate 14. The upper ends of the two guide shafts are respectively inserted into the second carrier plate 12. After the first cylinder 13 controls the lower end of the positioning plate 14 to abut against the positioning groove 26, it can prevent the pipe from rotating arbitrarily outside the inner positioning shaft 8, thus realizing the seam alignment operation.
[0035] It should be noted that this utility model is an automated welding device. In the initial stage of operation, a suitable inner positioning shaft 8 is selected and fitted onto the outside of the mounting shaft 7 according to the actual diameter of the pipe to be welded. After replacing and fixing the inner positioning shaft 8, a matching outer clamping sleeve 4 is also required. Then, the first cylinder 13 is vented and begins to work, pushing the positioning plate 14 downwards so that the lower end of the positioning plate 14 abuts against the positioning groove 26 at the upper end of the inner positioning shaft 8. At this time, the pipe can be fitted onto the outside of the inner positioning shaft 8, ensuring that two adjacent welding parts of the pipe are located on one side of the positioning plate 14, restricting the pipe from rotating outside the inner positioning shaft 8. Subsequently, the second cylinder 17 is vented and begins to work, outputting power to directly drive the connected... The slide plate 20 moves horizontally along the guide rail 16. When the slide plate 20 moves, it drives the gear 19 to rotate around the shaft 18 through the toothed rail 23. The rotation of the gear 19 will drive another set of toothed rails 23 to move synchronously with the slide plate 20. The two slide plates 20 slide relatively close along the guide rail 16, thereby driving the two outer clamps 4 fixed on the slide plate 20 to move synchronously relative to each other, so as to achieve a surrounding clamping of the pipe. During the clamping process, the two welded parts of the pipe will be forced against one side of the positioning plate 14. At the same time, the flushing alignment block 25 in the groove 24 will contact the end of the pipe through its own slope. Under the continuous clamping force, the two flushing alignment blocks 25 cooperate with each other to automatically push and align the two mating end faces of the pipe.
[0036] Finally, the first cylinder 13 moves the positioning plate 14 upward and away from the pipe. The main controller 2 controls the X-axis slide 9 to start. The X-axis slide 9 drives the first carrier plate 10, the second carrier plate 12 and the welding gun mechanism 11 to move in a straight line at a uniform speed along the straight seam direction of the pipe, so as to continuously and uninterruptedly weld the straight seam of the pipe and complete the entire straight seam welding operation. After the welding work is completed, the various execution parts of the equipment will automatically reset.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
