Description

Technical Field

[0001] This utility model relates to the field of welding technology for head production, and in particular to a welding device for head production. Background Technology

[0002] In the manufacturing of pressure vessels and chemical equipment, the welding quality of the head, as a key pressure-bearing component, directly affects the safety and service life of the equipment. Traditional head welding operations often rely on manual alignment and clamping, depending on the operator's experience to adjust the workpiece position. This is not only labor-intensive and inefficient, but also prone to poor weld formation due to alignment deviations, posing a risk of leakage. Existing welding equipment generally suffers from poor adaptability; the clamping mechanism is difficult to flexibly accommodate cylinders and heads of different diameters and thicknesses. When changing workpieces, frequent adjustments to the mechanical structure are required, which is time-consuming. At the same time, the welding gun angle adjustment is mostly fixed or manually fine-tuned, which cannot accurately fit the curved surface weld of the head, resulting in insufficient welding uniformity. With the increasing demands for production precision and efficiency in the manufacturing industry, there is an urgent need for a head welding device with a high degree of automation, strong adaptability, and stable control of welding quality.

[0003] Existing equipment relies heavily on manual alignment and clamping of the cylinder and head, which is not only time-consuming and labor-intensive, but also prone to weld alignment deviations due to human error, affecting welding quality. Furthermore, it is difficult to flexibly adapt to cylinders of different diameters and to accurately adapt to complex curved surface welds, resulting in poor welding adaptability.

The track passes through the bottom slot of the retainer, a limit frame is fixedly connected to the top of the retainer, and a clamping mechanism is movably connected inside the limit frame. A cylinder is movably connected inside the clamping mechanism.

[0008] As a further embodiment of this utility model: a cap is movably connected to one side of the cylinder, a support frame is fixedly connected to the top of the retainer, two electric retraction rods are fixedly connected to the top of the inside of the support frame, an adjustment mechanism is fixedly connected to the bottom of the electric retraction rods, a welding gun is fixedly connected to the bottom of the adjustment mechanism, and a cap is movably connected above the connection between the cylinder and the cap.

[0009] As a further embodiment of this utility model: the clamping mechanism includes a protective cylinder, a circular plate, a circular ring, an inner cylinder, a circular rod, an electric telescopic rod, and a clamping plate, wherein the circular plate is fixedly connected to one side of the connecting shaft, the protective cylinder is fixedly connected to one side of the circular plate, the inner cylinder is fixedly connected to one side of the circular plate, and a number of openings are respectively provided around the inner cylinder.

[0010] As a further embodiment of this utility model: the two round rods are movably connected to the openings around the inner cylinder, the clamping plates are fixedly connected to the bottom of the two round rods, the three electric telescopic rods are respectively fixedly connected to the inner wall of the inner cylinder, and the three clamping plates are respectively fixedly connected to the opposite inner sides of the three electric telescopic rods, and the rings are fixedly connected to the circumference of the inner cylinder.

[0011] As a further embodiment of this utility model: the adjustment mechanism includes a gear rod, a gear ring rod, a connecting plate, a rotary motor, a side plate, a rectangular frame, and a movable frame. The connecting plate is fixedly connected to the bottom of two electric retractable rods, the two side plates are fixedly connected to the bottom of the connecting plate, the rotary motor is fixedly connected to the bottom of the connecting plate, and the output end of the rotary motor passes through a side plate. The gear ring rod is movably connected to the opposite inner sides of the two side plates.

[0012] As a further embodiment of this utility model: the gear ring rod is fixedly connected to one side of the output end of the rotary motor, the rectangular frame is fixedly connected to the opposite inner sides of the two side plates, the gear rod is movably connected to the inside of the rectangular frame, and the round rods on both sides of the gear rod pass through the two sides of the rectangular frame respectively, and the gear rod and the gear ring rod mesh with each other, the movable frame is fixedly connected to both sides of the gear rod, and the welding gun is fixedly connected to the bottom of the movable frame.

[0013] Compared with the prior art, this utility model provides a welding device for the production of end caps, which has the following advantages:

[0014] 1. This welding device for producing end caps involves placing the cylinder and end cap to be welded in corresponding positions, starting the drive motor via a controller, and rotating the connecting shaft via a track. The clamping mechanism associated with the connecting shaft operates accordingly, while an electric push rod pushes the end cap closer to the cylinder. An electric retraction rod can adjust the height of the adjustment mechanism and the welding gun. The adjustment mechanism can change the angle of the welding gun, aligning it with the weld seam between the cylinder and the end cap. This allows for precise control of the connection between the cylinder and the end cap, eliminating the need for repeated manual adjustments, significantly shortening the preparation time before welding, improving the overall welding efficiency, ensuring the weld seam is always in the ideal welding position, and reducing welding defects caused by workpiece misalignment.

[0015] 2. This welding device for producing end caps controls the extension or retraction of an electric telescopic rod via a controller, which in turn moves the connected clamping plates. Because the clamping plates are fixed to a round rod inserted into the opening of the inner cylinder, the round rod can move within the opening of the inner cylinder, thereby causing the three clamping plates to move closer or further apart. This achieves the clamping and loosening of the cylinder placed in the space formed by the inner cylinder, the protective cylinder, and the ring, thus preventing the cylinder from deforming due to uneven force, ensuring the stability of the cylinder's posture during welding, and adapting to cylinders of different specifications. The clamping replaces manual labor, saving manpower and speeding up the clamping process.

[0016] 3. This welding device for head production controls the output of a rotary motor to rotate via a controller. The rotation of the rotary motor drives the gear ring rod to rotate. Because the gear ring rod meshes with the gear rod, the gear rod rotates within a rectangular frame. The movable frame is fixed to the gear rod, and the welding gun is connected to the bottom of the movable frame, thereby changing the tilt angle of the welding gun. Thus, the tilt angle of the welding gun can be precisely and flexibly adjusted to adapt to welding of welds with different curvatures and positions, improving the adaptability and quality of welding, making the welding operation more flexible, and meeting diverse welding needs for heads and cylinders.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] A welding apparatus for head production, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it includes a bottom fixing frame 1, a drive motor 2 is fixedly connected inside the bottom fixing frame 1, a retainer 3 is fixedly connected to the top of the bottom fixing frame 1, a slot is opened at the bottom of the retainer 3, a controller 13 is fixedly connected to one side of the retainer 3, an electric push rod 12 is movably connected to the inner wall of one side of the retainer 3, and a movable shaft is opened on the side of the electric push rod 12 that contacts the retainer 3, a cap 11 is movably connected to one side of the electric push rod 12, and a connecting shaft 15 is movably connected to the inner wall of the other side of the retainer 3.

[0028] A clamping mechanism 4 is fixedly connected to one side of the connecting shaft 15. A track 14 is movably connected around the connecting shaft 15 and the output end of the drive motor 2. The track 14 passes through the bottom slot of the retainer 3. A limit frame 5 is fixedly connected to the top of the retainer 3. The clamping mechanism 4 is movably connected inside the limit frame 5. A cylinder 6 is movably connected inside the clamping mechanism 4.

[0029] Furthermore, a head 11 is movably connected to one side of the cylinder 6, a support frame 7 is fixedly connected to the top of the retainer 3, two electric retraction rods 8 are fixedly connected to the top of the inside of the support frame 7, an adjustment mechanism 9 is fixedly connected to the bottom of the electric retraction rods 8, a welding gun 10 is fixedly connected to the bottom of the adjustment mechanism 9, and a head 11 is movably connected above the connection between the cylinder 6 and the head 11. The electric retraction rod 8 is model FSL40, the electric push rod 12 is model LACT80, and the controller 13 is model S7-1200.

[0030] During operation, by placing the cylinder 6 and end cap 11 to be welded in the corresponding positions, the drive motor 2 is started by the controller 13. The drive motor 2 rotates and drives the connecting shaft 15 to rotate via the track 14. The clamping mechanism 4 associated with the connecting shaft 15 operates accordingly. At the same time, the electric push rod 12 pushes the end cap 11 closer to the cylinder 6. The electric retraction rod 8 can adjust the height of the adjustment mechanism 9 and the welding gun 10. The adjustment mechanism 9 can change the angle of the welding gun 10 so that the welding gun 10 is aligned with the weld between the cylinder 6 and the end cap 11. Thus, the docking of the cylinder 6 and the end cap 11 is precisely controlled without repeated manual adjustments, which greatly shortens the preparation time before welding, improves the overall welding efficiency, and ensures that the weld is always in the ideal welding position, reducing welding defects caused by workpiece misalignment.

[0031] In order to fix and clamp the cylinder 6, such as Figure 3 and Figure 4 As shown, the clamping mechanism 4 includes a protective cylinder 401, a circular plate 402, a circular ring 403, an inner cylinder 404, a circular rod 405, an electric telescopic rod 406, and a clamping plate 407. The circular plate 402 is fixedly connected to one side of the connecting shaft 15, the protective cylinder 401 is fixedly connected to one side of the circular plate 402, and the inner cylinder 404 is fixedly connected to one side of the circular plate 402. Several openings are respectively provided around the inner cylinder 404.

[0032] Two round rods 405 are movably connected to the openings around the inner cylinder 404. Clamping plates 407 are fixedly connected to the bottom of the two round rods 405. Three electric telescopic rods 406 are fixedly connected to the inner wall of the inner cylinder 404, and the three clamping plates 407 are fixedly connected to the opposite inner sides of the three electric telescopic rods 406. A ring 403 is fixedly connected to the inner cylinder 404. The model of the electric telescopic rod 406 is FY011.

[0033] During operation, the electric telescopic rod 406 is extended or retracted by the controller 13, which drives the connected clamping plate 407 to move. Since the clamping plate 407 is fixed to the round rod 405 that passes through the opening of the inner cylinder 404, the round rod 405 can move within the opening of the inner cylinder 404, thereby causing the three clamping plates 407 to move closer or further apart, realizing the clamping and loosening of the cylinder 6 placed in the space formed by the inner cylinder 404, the protective cylinder 401, the ring 403, etc. This avoids the deformation of the cylinder 6 due to uneven force, ensures the stability of the cylinder 6 during welding, and can adapt to cylinders 6 of different specifications. Clamping replaces manual labor, saving manpower and speeding up the clamping speed.

[0034] In order to adjust the tilt angle of the welding gun 10, such as Figure 5 As shown, the adjustment mechanism 9 includes a gear rod 901, a gear ring rod 902, a connecting plate 903, a rotary motor 904, a side plate 905, a rectangular frame 906, and a movable frame 907. The connecting plate 903 is fixedly connected to the bottom of the two electric retractable rods 8, the two side plates 905 are fixedly connected to the bottom of the connecting plate 903, the rotary motor 904 is fixedly connected to the bottom of the connecting plate 903, and the output end of the rotary motor 904 passes through one of the side plates 905. The gear ring rod 902 is movably connected to the opposite inner sides of the two side plates 905.

[0035] The gear ring rod 902 is fixedly connected to one side of the output end of the rotary motor 904, the rectangular frame 906 is fixedly connected to the opposite inner sides of the two side plates 905, the gear rod 901 is movably connected to the inside of the rectangular frame 906, and the round rods on both sides of the gear rod 901 pass through the two sides of the rectangular frame 906 respectively, and the gear rod 901 and the gear ring rod 902 mesh with each other, the movable frame 907 is fixedly connected to both sides of the gear rod 901, and the welding gun 10 is fixedly connected to the bottom of the movable frame 907.

[0036] During operation, the output end of the rotary motor 904 is controlled by the controller 13 to rotate, which drives the gear ring rod 902 to rotate. Since the gear ring rod 902 meshes with the gear rod 901, the gear rod 901 rotates within the rectangular frame 906. The movable frame 907 is fixed to the gear rod 901, and the welding gun 10 is connected to the bottom of the movable frame 907, thereby causing the welding gun 10 to change its tilt angle. Thus, the tilt angle of the welding gun 10 can be adjusted precisely and flexibly to adapt to welding seams of different curvatures and positions, improving the adaptability and quality of welding, making the welding operation more flexible, and able to meet the diverse welding needs of the head 11 and the cylinder 6.

[0037] Working principle: By placing the cylinder 6 to be welded and the end cap 11 in the corresponding positions, the controller 13 controls the extension or retraction of the electric telescopic rod 406, which drives the connected clamping plate 407 to move. Since the clamping plate 407 is fixed to the round rod 405 that passes through the opening of the inner cylinder 404, the round rod 405 can move within the opening of the inner cylinder 404, thereby causing the three clamping plates 407 to move closer or further away from each other, thus achieving the clamping and loosening of the cylinder 6 placed in the space formed by the inner cylinder 404, the protective cylinder 401, the ring 403, etc.

[0038] Next, the controller 13 starts the drive motor 2. The drive motor 2 rotates and drives the connecting shaft 15 to rotate via the track 14. The connecting shaft 15 drives the circular plate 402, and at the same time, the electric push rod 12 pushes the end cap 11 closer to the cylinder 6.

[0039] The output of the rotary motor 904 is controlled by the controller 13 to rotate, which drives the gear ring rod 902 to rotate. Since the gear ring rod 902 meshes with the gear rod 901, the gear rod 901 rotates within the rectangular frame 906. The movable frame 907 is fixed to the gear rod 901, and the welding gun 10 is connected to the bottom of the movable frame 907, thereby driving the welding gun 10 to change its tilt angle. The electric retraction rod 8 adjusts the height of the welding gun 10 so that the welding gun 10 is aligned with the weld between the cylinder 6 and the end cap 11.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
