Description

Technical Field

[0001] This application relates to the field of welding technology, and in particular to a welding device for a retaining ring for a spinning box. Background Technology

[0002] A spinning box is a chemical fiber production device that spins polymer melts or solutions into fibers. The retaining ring inside the spinning box is a key component. Its main function is to fix the spinneret and ensure its stability during the spinning process, preventing displacement or vibration, thereby ensuring the quality and consistency of the fibers. The manufacturing process of the spinning box retaining ring usually requires four annular sheet metal parts to be spliced ​​into a complete ring structure through welding.

[0003] In the existing technology, when welding the spinning box retaining ring, workers need to frequently move the welding torch to match the welding trajectory of the ring-shaped workpiece. This welding method is difficult to operate and is prone to inconsistent weld penetration due to uneven worker movement speed or positioning deviation. This can lead to local overheating deformation or incomplete welding of the welded retaining ring, resulting in a reduction in the welding quality of the produced retaining ring and significant deficiencies. Utility Model Content

[0004] To improve the welding quality of retaining rings, this application provides a welding device for retaining rings used in spinning boxes.

[0005] The welding device for the retaining ring of the spinning box provided in this application adopts the following technical solution:

[0006] A welding device for a retaining ring for a spinning box includes a frame, a worktable rotatably mounted on the frame, a protective shell mounted on the frame, a rotating assembly mounted on the protective shell, the rotating assembly including a support shaft rotatably connected to the protective shell, the worktable mounted on the support shaft, a first worm gear coaxially mounted on the end of the support shaft extending to the protective shell, a rotating motor mounted on the outer surface of the protective shell, and a first worm gear meshing with the first worm gear on the output shaft of the rotating motor.

[0007] By adopting the above technical solution, when welding the retaining ring, the retaining ring is first placed on the worktable. Then, the worker starts the rotating motor, which drives the first worm gear to rotate. The first worm gear drives the first worm wheel to rotate, which in turn drives the support shaft to rotate. The support shaft drives the worktable to rotate at a constant speed, thereby achieving uniform rotation of the retaining ring during the welding process. At this time, the worker does not need to manually adjust the position of the welding torch. He only needs to keep the welding torch fixed and aligned with the initial welding point to achieve continuous welding of the retaining ring. This effectively avoids weld quality problems caused by uneven worker movement speed or positioning deviation, thereby improving the welding quality of the retaining ring.

[0008] Optionally, a rotating shaft is coaxially disposed on the protective shell, the rotating shaft is rotatably connected to the frame, and an adjustment component for driving the rotating shaft to rotate is disposed on the frame.

[0009] By adopting the above technical solution, when it is necessary to adjust the welding position of the retaining ring, the worker drives the rotating shaft to rotate through the adjustment component. The rotating shaft drives the protective shell to rotate, and the protective shell will drive the worktable to rotate along its own diameter, thereby realizing the adjustment of the tilt of the worktable, so that the welding point is adjusted to the angle suitable for the worker's welding, thereby improving the adaptability of the welding device to different welding positions.

[0010] Optionally, the adjustment assembly includes an incomplete gear fixedly connected coaxially to the rotating shaft, a drive gear rotatably connected to the inner side wall of the frame and meshing with the incomplete gear, a second worm gear coaxially disposed on the drive gear, an operating wheel rotatably connected to the frame, and a second worm coaxially disposed on the operating wheel and meshing with the second worm gear.

[0011] By adopting the above technical solution, the worker rotates the operating wheel, which drives the second worm gear to rotate. The second worm gear drives the second worm wheel to rotate, which in turn drives the drive gear to rotate. The drive gear drives the incomplete gear to rotate, which in turn drives the drive shaft to rotate. The drive shaft drives the worktable to rotate around its own diameter. When the worktable and the retaining ring are adjusted to the welding point, the worker stops rotating the operating wheel. This setting enables the worker to manually and precisely control the tilt angle of the worktable, improving the adaptability of the worker's operation.

[0012] Optionally, a connecting shaft is coaxially provided on the end face of the worktable near the support shaft, and the connecting shaft is detachably connected to the support shaft via a connecting flange.

[0013] By adopting the above technical solution, the connection flange enables a detachable connection between the connecting shaft and the worktable, making it convenient for workers to replace the worktable with a suitable size of retaining ring, thus meeting the welding needs of various specifications of retaining ring.

[0014] Optionally, a limit block is provided at the end of the rotating shaft away from the incomplete gear, and a limit arc groove is provided on the inner side wall of the frame to slide with the limit block.

[0015] By adopting the above technical solution, the rotating shaft drives the limiting block to slide in the limiting arc groove during rotation. When the limiting block abuts against the inner side wall of the limiting arc groove, the limiting block cannot continue to move, thereby limiting the rotation angle of the rotating shaft. This avoids the workbench tilting too much due to worker error, which could cause the retaining ring to fall off the workbench surface and ensure the stable progress of the welding process.

[0016] Optionally, the worktable surface is provided with multiple moving slots, all of which are parallel to the radial direction of the worktable. Each moving slot is rotatably connected to a bidirectional lead screw. The two ends of the bidirectional lead screw with opposite threads are respectively threaded to a fastening plate and a protective plate. The protective plate is disposed on the outer periphery of the worktable. The protective plate and the fastening plate are slidably connected in the moving slot. The end of each bidirectional lead screw extends outside the worktable and is coaxially provided with a fastening wheel.

[0017] By adopting the above technical solution, before welding, the worker places the retaining ring between the fixed plate and the protective plate. Then, the worker rotates the fastening wheel in sequence. The fastening wheel drives the double-acting screw to rotate, and the double-acting screw drives the fastening plate and the protective plate to move together toward the retaining ring until the fastening plate and the protective plate are tightly attached to the inner and outer surfaces of the retaining ring. This achieves the fixation of the retaining ring on the worktable, effectively preventing the retaining ring from moving during the welding process and causing the welding trajectory to deviate. This further ensures the uniformity of the weld and improves the welding quality of the retaining ring.

[0018] Optionally, rubber pads are provided on the opposite end faces of the protective plate and the fastening plate.

[0019] By adopting the above technical solution, the rubber pad increases the friction of the clamping surface, prevents the retaining ring from sliding, and avoids the fastening plate and the protective plate from directly contacting the surface of the retaining ring and causing scratches, thus protecting the appearance quality of the retaining ring.

[0020] Optionally, weight-reduction grooves are provided at both opposite ends of the frame.

[0021] By adopting the above technical solution, the weight reduction groove reduces the overall weight of the frame, making it easier to move and install the welding equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In this embodiment of the application, by setting a rotating component and a worktable, the rotating component drives the worktable to rotate, and the worktable drives the retaining ring to rotate at a constant speed during the welding process. At this time, the worker does not need to manually adjust the position of the welding gun. He only needs to keep the welding gun fixed and aligned with the initial welding point to achieve continuous welding of the retaining ring. This effectively avoids weld quality problems caused by uneven worker movement speed or positioning deviation, thereby improving the welding quality of the retaining ring.

[0024] 2. In this embodiment of the application, by setting an adjustment component, when it is necessary to adjust the welding position of the retaining ring, the worker drives the rotating shaft to rotate through the adjustment component. The rotating shaft drives the protective shell to rotate. At this time, the protective shell will drive the worktable to rotate along its own diameter, thereby realizing the adjustment of the tilt of the worktable, so that the welding point is adjusted to the angle suitable for the worker's welding, thereby improving the adaptability of the welding device to different welding positions.

[0025] 3. In this embodiment of the application, by setting a fastening plate and a protective plate, the retaining ring is fixed by the fastening plate and the protective plate, which effectively prevents the retaining ring from moving during the welding process and causing the welding trajectory to deviate, thereby further ensuring the uniformity of the weld and improving the welding quality of the retaining ring.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a welding device for a retaining ring for a spinning box.

[0033] Reference Figure 1 A welding device for a retaining ring for a spinning box includes a frame 1, on which a worktable 2 for placing the retaining ring is rotatably connected. The worktable 2 is disc-shaped, and weight-reducing grooves 101 are provided on opposite sides of the bottom end of the frame 1. The weight of the frame 1 is reduced by the weight-reducing grooves 101, making it easier for workers to move the frame 1 to the welding position.

[0034] Reference Figure 1 and Figure 2A protective shell 3 is rotatably connected to the frame 1. A rotating assembly 4 is provided on the protective shell 3. Specifically, the rotating assembly 4 includes a support shaft 41 rotatably connected inside the protective shell 3. The center of the worktable 2 is located on the axis of the support shaft 41. A connecting shaft 21 is fixedly connected to the end face of the worktable 2 facing the support shaft 41. The connecting shaft 21 is coaxial with the support shaft 41. The connecting shaft 21 and the support shaft 41 are detachably connected through a connecting flange 5. This makes it convenient for workers to replace the worktable 2 with a suitable size of retaining ring according to different sizes, so as to meet the welding needs of various specifications of retaining rings.

[0035] Reference Figure 1 and Figure 2 The end of the support shaft 41 away from the workbench 2 extends into the interior of the protective shell 3 and is coaxially fixedly connected to the first worm gear 42. A rotating motor 43 is fixedly installed on the outer surface of the protective shell 3. The output shaft of the rotating motor 43 is coaxially fixedly connected to the first worm 44 that meshes with the first worm gear 42. Both the first worm gear 42 and the first worm 44 are rotatably connected inside the protective shell 3.

[0036] When welding the retaining ring, the retaining ring is first placed on the worktable 2. Then, the worker starts the rotating motor 43, which drives the first worm gear 44 to rotate. The first worm gear 44 drives the first worm wheel 42 to rotate, which in turn drives the support shaft 41 to rotate. The support shaft 41 drives the worktable 2 to rotate at a constant speed, thus achieving uniform rotation of the retaining ring during the welding process. At this time, the worker does not need to manually adjust the position of the welding torch. He only needs to keep the welding torch fixed and aligned with the initial welding point to achieve continuous welding of the retaining ring. This effectively avoids weld quality problems caused by uneven worker movement speed or positioning deviation, thereby improving the welding quality of the retaining ring.

[0037] Reference Figure 1 and Figure 3 A rotating shaft 31 is fixedly connected to the protective shell 3. The rotating shaft 31 is coaxially arranged with the axis of the protective shell 3 along the length direction. Both ends of the rotating shaft 31 are rotatably connected to the frame 1. An adjustment component 6 is provided on the frame 1. Specifically, the adjustment component 6 includes an incomplete gear 61 that is coaxially fixedly connected to the rotating shaft 31. A drive gear 62 that meshes with the incomplete gear 61 is rotatably connected to the inner side wall of the frame 1. A second worm gear 63 is coaxially fixedly connected to the drive gear 62. An operating wheel 64 is rotatably connected to the frame 1. A second worm 65 that meshes with the second worm gear 63 is coaxially fixedly connected to the operating wheel 64.

[0038] Reference Figure 1 and Figure 3A limiting block 311 is fixedly connected to the end of the rotating shaft 31 away from the incomplete gear 61. A limiting arc groove 102 is provided on the inner side wall of the frame 1 to slide with the limiting block 311. During the rotation of the rotating shaft 31, the limiting block 311 is driven to slide in the limiting arc groove 102. When the limiting block 311 abuts against the inner side wall of the limiting arc groove 102, the limiting block 311 cannot continue to move, thereby limiting the rotation angle of the rotating shaft 31.

[0039] When the welding position of the retaining ring needs to be adjusted, the worker rotates the operating wheel 64, which drives the second worm gear 65 to rotate. The second worm gear 65 drives the second worm wheel 63 to rotate, which in turn drives the drive gear 62 to rotate. The drive gear 62 drives the incomplete gear 61 to rotate, which in turn drives the drive shaft to rotate. The rotating shaft 31 drives the protective shell 3 to rotate. At this time, the protective shell 3 will drive the worktable 2 to rotate along its own diameter, thereby realizing the adjustment of the tilt of the worktable 2, so that the welding point is adjusted to the angle suitable for the worker's welding, thereby improving the adaptability of the welding device to different welding positions.

[0040] Reference Figure 4 The workbench 2 has multiple moving slots 7 on its surface. In this embodiment, there are four moving slots 7, all of which are parallel to the radial direction of the workbench 2. Each moving slot 7 is rotatably connected to a bidirectional lead screw 8, which is parallel to the radial direction of the workbench 2. The two ends of the bidirectional lead screw 8 with opposite thread directions are respectively threaded to a fastening plate 81 and a protective plate 82. The protective plate 82 is located near the outer periphery of the workbench 2. Both the protective plate 82 and the fastening plate 81 are slidably connected in the moving slot 7. The end of each bidirectional lead screw 8 extends to the outside of the workbench 2 and is coaxially fixedly connected to a fastening wheel 83.

[0041] Reference Figure 4 Both the fastening plate 81 and the protective plate 82 have rubber pads 9 detachably connected to their opposite end faces via Velcro. The rubber pads 9 effectively increase the friction between the retaining ring and the fastening plate 81 and the protective plate 82.

[0042] Before welding, the worker places the retaining ring between the fixed plate and the protective plate 82. Then, the worker rotates the fastening wheel 83 in sequence. The fastening wheel 83 drives the double-acting screw 8 to rotate. The double-acting screw 8 drives the fastening plate 81 and the protective plate 82 to move together toward the retaining ring until both rubber pads 9 are tightly attached to the inner and outer surfaces of the retaining ring. This achieves the fixation of the retaining ring on the workbench 2, effectively preventing the retaining ring from moving during the welding process and causing the welding trajectory to deviate. This further ensures the uniformity of the weld and improves the welding quality of the retaining ring.

[0043] The implementation principle of the welding device for a retaining ring for a spinning box according to an embodiment of this application is as follows: When welding the retaining ring, the retaining ring is first placed on the workbench 2. Then, the worker starts the rotating motor 43, which drives the first worm gear 44 to rotate. The first worm gear 44 drives the first worm wheel 42 to rotate, which in turn drives the support shaft 41 to rotate. The support shaft 41 drives the workbench 2 to rotate at a uniform speed, thereby achieving uniform rotation of the retaining ring during the welding process. At this time, the worker does not need to manually adjust the position of the welding gun. He only needs to keep the welding gun fixed and aligned with the initial welding point to achieve continuous welding of the retaining ring. This effectively avoids weld quality problems caused by uneven worker movement speed or positioning deviation, thereby improving the welding quality of the retaining ring.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
