Description

Technical Field

[0001] This utility model belongs to the technical field of roller welding equipment, and specifically relates to a roller welding device. Background Technology

[0002] In current industrial production, rollers, as core components of conveying and transmission systems, are widely used in industries such as steel metallurgy, papermaking, packaging, and building materials. Taking the steel metallurgy industry as an example, the welding quality of rollers in key equipment such as continuous casting machine roller conveyors and rolling mill roller systems directly affects the surface finish of steel and the continuity of production.

[0003] Existing roller welding operations mostly rely on manual labor, which is not only labor-intensive but also suffers from low welding position accuracy and low welding efficiency. Some traditional welding equipment lacks adaptive adjustment functions for rollers of different lengths, requiring frequent changes of tooling fixtures, which is cumbersome and time-consuming. At the same time, the welding torch positioning often relies on manual hand-held operation, making it difficult to ensure stability during the welding process, resulting in inconsistent welding quality and failing to meet the needs of industrial mass production. Therefore, a roller welding device is provided to solve the above technical problems. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a roller welding device to solve the problems of poor tooling applicability and low welding quality in the prior art when welding rollers.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roller welding device includes a base frame. Two slide rails and a fixed seat are symmetrically fixedly installed on the upper surface of the base frame. A vertical plate is fixedly installed on the upper surface of the fixed seat. Two lifting wheels are rotatably installed on the left and right sides of the vertical plate via a rotating shaft. A positioning and driving device for driving the roller to rotate is installed above the vertical plate. Two side lifting and positioning devices are slidably installed between the two slide rails. The two side lifting and positioning devices are located on the left and right sides of the fixed seat, respectively, and are used to position and lift the two ends of the roller. Each side lifting and positioning device has an adjustable welding torch support and positioning device fixedly installed inside it.

[0007] In the above technical solution, the positioning and driving device includes a trapezoidal frame. The front end of the trapezoidal frame is rotatably connected to the upright plate via a rotating shaft. Four T-shaped suspension rods are slidably installed through the upper surface of the trapezoidal frame. Springs are fixedly installed between each suspension rod and the upper surface of the trapezoidal frame. The springs are located on the outside of the corresponding suspension rods. A lifting plate is fixedly installed between the lower surfaces of the four suspension rods. A dual-output motor is fixedly installed on the lifting plate. Both output ends of the dual-output motor are fixedly installed with drive wheels via couplings. A through opening is provided at the rear end of the trapezoidal frame, and an insertion slot is provided at the rear end of the upright plate. A bolt and nut assembly is inserted and installed between the insertion slot and the through opening.

[0008] In the above technical solution, the side-support positioning device includes a support base, and two slides are symmetrically fixedly installed on the lower surface of the support base. The slides are slidably installed on the corresponding slide rails, and locking components are provided between the slides and the corresponding slide rails. The upper end of the support base is L-shaped, and two positioning wheels are rotatably installed on the side of the upper end of the support base near the fixed base via a rotating shaft. The side of the positioning wheels away from the fixed base is integrally formed with a retaining edge.

[0009] In the above technical solution, the welding torch support and positioning device includes a vertical rod, which is fixedly installed on the upper surface of the corresponding support base. The top of the vertical rod has an installation groove, and a T-shaped sleeve is rotatably installed in the installation groove via a rotating shaft.

The multiple damping pads are all sleeved on the outer surface of the rotating shaft in the installation groove. A support rod is inserted into the T-shaped sleeve, and a mounting ring for supporting the welding torch is fixedly installed at the rear end of each support rod.

[0010] In the above technical solution, butterfly bolts are threaded through the outer surfaces of the T-sleeve and the mounting ring. The lower surface of the butterfly bolt at the front end fits against the outer surface of the support rod, and the butterfly bolt at the rear end is used to lock and fix the welding torch inside the mounting ring.

[0011] The roller welding device of this utility model has the following advantages compared with the prior art:

[0012] This invention features an adjustable side-mounted support and positioning device that allows for flexible adjustment of the positioning wheel position according to the roller length.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-5 This utility model provides a technical solution:

[0021] A roller welding device includes a base frame 1. Two slide rails 11 and a fixed seat 2 are symmetrically fixedly installed on the upper surface of the base frame 1. A vertical plate 21 is fixedly installed on the upper surface of the fixed seat 2. Two lifting wheels 22 are rotatably installed on the left and right sides of the vertical plate 21 via a rotating shaft. The lifting wheels 22 are used to lift the middle part of the roller. Utilizing the characteristics of the wheels, the roller can be easily rotated to adjust the welding position while being lifted. A positioning drive device 3 for driving the roller to rotate is installed above the vertical plate 21. Two side lifting and positioning devices 4 are slidably installed between the two slide rails 11. The two side lifting and positioning devices 4 are located on the left and right sides of the fixed seat 2, respectively, and are used to position and lift the two ends of the roller. Each side lifting and positioning device 4 has an adjustable welding torch support and positioning device 5 fixedly installed inside it. The welding torch support and positioning device 5 is used to support and position the welding torch, replacing manual handling for a long time and reducing welding labor.

[0022] It should be noted that, in combination Figure 1 and Figure 2 As shown, the positioning and driving device 3 includes a trapezoidal frame 31. The front end of the trapezoidal frame 31 is rotatably connected to the upright plate 21 via a rotating shaft. Four T-shaped lifting rods 32 are slidably mounted through the upper surface of the trapezoidal frame 31. Springs 321 are fixedly installed between each lifting rod 32 and the upper surface of the trapezoidal frame 31. The springs 321 are located on the outer side of the corresponding lifting rod 32. A lifting plate 33 is fixedly installed between the lower surfaces of the four lifting rods 32. A dual-output motor 34, which is a stepper motor, is fixedly installed on the lifting plate 33. It is used by connecting to an external power supply and an external controller. The external controller is used to control the start and stop of the dual-output motor 34. Both output ends of the dual-output motor 34 are fixedly mounted with drive wheels 35 through couplings. The rear end of the trapezoidal frame 31 has a through opening 36, and the rear end of the upright plate 21 has a through opening 211. A bolt and nut assembly 37 is inserted between the through opening 36 and the bolt and nut assembly 37, which consists of a bolt and a nut. The two are screwed together to fix the upright plate 21 and the trapezoidal frame 31.

[0023] When using the positioning and driving device 3, the placed roller is flipped so that the drive wheel 35 is in contact with the outer surface of the roller. Then, the position of the rear end opening 36 of the trapezoidal frame 31 is aligned with the position of the insertion port 211 of the upright plate 21. Subsequently, the bolt and nut assembly 37 is fixedly installed between the insertion port 211 and the opening 36. At this time, the drive wheel 35 is tightly in contact with the outer surface of the roller under the action of the spring 321. When the dual-output motor 34 is started, it can drive the two drive wheels 35 to rotate, thereby using the friction between the drive wheel 35 and the roller to drive the roller to rotate, so as to adjust the welding position at the end of the roller and make the welding operation more convenient and efficient.

[0024] In addition, combined Figure 1 , Figure 3 and Figure 4 As shown, the side support positioning device 4 includes a support base 41. Two slides 42 are symmetrically fixedly installed on the lower surface of the support base 41. The slides 42 are slidably installed on the corresponding slide rails 11. Locking components 43 are provided between the slides 42 and the corresponding slide rails 11. The locking components 43 include bolts and handles. The bolts are welded to the side surface of the handles and are threaded through and installed on the outer surface of the slides 42. The handles can drive the bolts to rotate. After the bolts are pressed against the outer surface of the base frame 1, the position of the support base 41 can be fixed.

[0025] The upper end of the support base 41 is L-shaped, and two positioning wheels 44 are rotatably mounted on the side of the upper end of the support base 41 near the fixed base 2 via a rotating shaft. The side of the positioning wheels 44 away from the fixed base 2 is integrally formed with a retaining edge 441. When the position of the support base 41 is fixed, the retaining edge 441 can cover the end of the roller, preventing the roller from moving left and right during rotation and affecting the welding effect.

[0026] Before use, the locking piece 43 can be loosened, and the position of the support seat 41 can be adjusted by sliding along the outer surface of the slide rail 11 to adjust the support position of the positioning wheel 44, so as to support rollers of different lengths.

[0027] In addition, combined Figure 1 , Figure 3 and Figure 5As shown, the welding torch support and positioning device 5 includes a vertical rod 51, which is fixedly installed on the upper surface of the corresponding support base 41. The top of the vertical rod 51 has an installation groove 511. A T-shaped sleeve 52 is rotatably installed in the installation groove 511 via a rotating shaft. Multiple damping pads 512 are installed between the lower outer side of the T-shaped sleeve 52 and the installation groove 511. The multiple damping pads 512 are all sleeved on the outer surface of the rotating shaft in the installation groove 511. A support rod 53 is inserted into the T-shaped sleeve 52. The rear end of the support rod 53 is fixedly installed with an installation ring 54 for supporting the welding torch. The installation of the damping pads 512 can make the T-shaped sleeve 52 and the vertical rod 51 have a certain damping, ensuring that after the welding torch is installed in the installation ring 54, the support rod 53 will not change its support position due to the weight of the welding torch, thus ensuring the stability of the welding torch position and ensuring the welding effect.

[0028] Finally, as Figure 5 As shown, butterfly bolts 55 are threaded through and installed on the outer surfaces of the T-sleeve 52 and the mounting ring 54. The lower surface of the front butterfly bolt 55 fits against the outer surface of the support rod 53. After the welding torch is inserted into the mounting ring 54, the rear butterfly bolt 55 is tightened to lock and fix the welding torch in the mounting ring 54.

[0029] Working principle: Before operation, based on the length of the roller to be welded, the positions of the left and right positioning wheels 44 are adjusted to position it in a suitable lifting position for the roller length. Then, the trapezoidal frame 31 is flipped open, and with the help of an external crane or hoisting equipment, the roller is lifted between the two positioning wheels 44, ensuring that the outer surface of the roller is tightly fitted with the outer surface of the lifting wheel 22, with the middle of the roller supported by the lifting wheel 22. Next, the trapezoidal frame 31 is flipped towards the roller, and the trapezoidal frame 31 is fixedly connected to the upright plate 21 using the bolt and nut assembly 37. Under the elastic force of the spring 321, the drive wheel 35 forms a close contact with the outer surface of the roller. Next, two welding torches are inserted into the mounting rings 54 on both sides and pre-fixed with butterfly bolts 55. Then, the axial position of the sliding adjustment support rod 53 within the T-sleeve 52 is adjusted, and the circumferential angle is adjusted by rotating the T-sleeve 52 to ensure that the welding torch working area is precisely aligned with the welding position at the end of the roller. After alignment, the butterfly bolts 55 on the T-sleeve 52 are tightened to achieve positioning. Finally, the dual-output motor 34 is controlled by an external controller to drive the drive wheel 35 to rotate at a constant linear speed. The friction between the drive wheel 35 and the roller drives the roller to rotate, so that the welding position is dynamically adjusted with the rotation of the roller. At this time, the welding torches on both sides simultaneously perform welding operations on both ends of the roller. Through the process design of automated rotation positioning and double-sided collaborative welding, the welding efficiency is significantly improved.
