Description

Technical Field

[0001] This utility model relates to the field of roll processing technology, and in particular to an automatic welding device for roll circumferential seams. Background Technology

[0002] A drum is a widely used piece of equipment in the industrial field. Its core function is to store and transport linear materials, such as steel wire ropes, cables, and yarns, through axial rotation, achieving orderly storage and controlled release, and avoiding tangling or knotting. Circumferential welding of drum-type workpieces is a key processing technology in drum manufacturing, and the welding quality directly affects the performance and lifespan of the drum.

This makes it difficult to ensure accurate alignment of the two components, resulting in defects such as inconsistent weld width and misalignment, which affect weld strength and appearance quality. In addition, the equipment is complex to adjust for drum components of different diameters, has limited adaptability, and cannot meet diverse production needs. Utility Model Content

The output shaft of the first motor 22 extends into the first guide seat 2 and is fixedly connected to a bidirectional screw 23. The other end of the bidirectional screw 23 is threaded through the two first sliders 21 and is rotatably connected to the other inner wall of the first guide seat 2. A vertical plate 24 is fixedly connected to the upper side wall of the first slider 21. The second guide seat 3 is fixedly installed on the upper side wall edge of the base 1. The second guide seat 3 has a second slider 31 slidably installed inside it. The second motor 32 is installed on one side outer wall of the second guide seat 3. The output shaft of the second motor 32 extends into the second guide seat 3 and is fixedly connected to a screw 33. The other end of the screw 33 is threaded through the second slider 31 and rotatably connected to the other side inner wall of the second guide seat 3. An L-shaped support plate 34 is fixedly connected to the upper side wall of the second slider 31. Positioning mechanism 4 is mounted on vertical plate 24. Positioning mechanism 4 is used to position the drum and drive the drum to rotate. Welding mechanism 5 is set on L-shaped support plate 34 and is used to weld the circumferential seam between the two drums.

[0019] The above structure enables high-quality welding of the circumferential seam between the two drums.

[0020] The positioning mechanism 4 includes a drive motor 41, which is mounted on one side wall of the upright plate 24. The output shaft of the drive motor 41 passes through the upright plate 24 and is fixedly connected to a rotating cylinder 42. A follower cylinder 43 is fixedly connected to the outer wall of the rotating cylinder 42 away from the upright plate 24, and a cylinder 45 is installed on the inner wall. An action plate 44 is provided inside the follower cylinder 43. The telescopic end of the cylinder 45 is fixedly connected to the action plate 44. Four adapter rods 46 are provided on the sliding ring of the cylinder wall of the follower cylinder 43. An arc-shaped positioning plate 47 is fixedly connected to one end of the adapter rod 46 outside the follower cylinder 43. Two hinge plates 48 are hinged to the other end of the adapter rod 46. The other ends of the two hinge plates 48 are hinged to the center of the action plate 44.

[0021] By setting up the above structure, it is possible to tighten and position drums of different diameters from inside the drum. This positioning method can ensure that the axes of the two drums to be welded are accurately aligned, which significantly improves the positioning accuracy and thus effectively guarantees the welding quality.

[0022] The welding mechanism 5 includes an electric slide rail 51, which is fixedly installed on the upper outer wall of the L-shaped support plate 34. A welding machine 52 is fixedly connected to the slide seat of the electric slide rail 51, and the welding machine 52 has a welding gun 53.

[0023] The above structure enables the position adjustment of the welding torch 53, allowing for flexible adjustment of the position of the welding torch 53 for welding of different pipe diameters.

[0024] Among them, a connecting rod 341 is fixedly connected to the upper inner wall of the L-shaped support plate 34, and an arc-shaped electromagnetic heater 6 is fixedly connected to the other end of the connecting rod 341.

[0025] The above structure allows for preheating of the circumferential seam of the drum before welding. This preheating process effectively reduces stress generated during welding, significantly lowering the risk of welding cracks.

[0026] Among them, an annular guide groove 241 is provided on the side wall of the upright plate 24 near the rotating drum 42, and a guide rod 421 is slidably provided in the annular guide groove 241, with one end of the guide rod 421 fixedly connected to the rotating drum 42.

[0027] The above structure provides support and guidance for the rotating drum 42, making its rotation more stable.

[0028] The inner wall of the follower cylinder 43 has two symmetrically distributed guide grooves 431, and the action plate 44 slides in conjunction with the guide grooves 431.

[0029] The above structure enables the guidance of the action plate 44.

[0030] Among them, the outer wall of the arc-shaped positioning plate 47 is provided with an anti-slip pad 471.

[0031] By designing the above structure, wear can be avoided during drum positioning, and the friction between the drum and the drum can be increased, enabling the drum to rotate stably.

[0032] It should be noted that this utility model is an automatic welding device for circumferential seams on rolls. In use, the two rolls to be welded are respectively fitted onto the rotating drum 42. Then, the cylinder 45 is activated. The telescopic end of the cylinder 45 drives the action plate 44 to move closer to the rotating drum 42. When the action plate 44 moves, under the action of the hinge plate 48, it forces the four adapter rods 46 to extend synchronously from the follower drum 43, causing the four arc-shaped positioning plates 47 to tighten the rolls. After tightening, the axes of the two rolls will be aligned. Then, the first motor 22 is activated. The output shaft of the first motor 22 can drive the bidirectional screw 23 to rotate. When the bidirectional screw 23 rotates, it can bring the two first sliders 21 closer together, thereby bringing the two rolls closer together and fitting them together. Then, check whether the position of the welding torch 53 is appropriate. When adjusting the position of the welding torch 53, the position of the welding torch 53 is changed by controlling the forward and reverse rotation of the second motor 32. The output shaft of the second motor 32 can drive the screw 33 to rotate. When the screw 33 rotates, it can cause the second slider 31 to move the L-shaped support plate 34, thereby changing the position of the welding torch 53. Then, the distance between the welding torch 53 and the circumferential seam is controlled by controlling the electric slide rail 51. During welding, the arc-shaped electromagnetic heater 6 preheats the circumferential seam of the drum, and the welding torch 53 welds the preheated circumferential seam. During the welding process, the output shaft of the drive motor 41 can drive the rotating drum 42 to rotate at a constant speed. The rotation of the rotating drum 42 can cause the follower drum 43 to rotate, thereby causing the arc-shaped positioning plate 47 to drive the drum to rotate at a constant speed, thus completing the welding of the circumferential seam.

[0033] It should be noted that the control method of this utility model is automatic control through an STM32 microcontroller. The control circuit of the controller can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. Therefore, this utility model will not explain the control method and circuit connection in detail.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
