A ship steel plate welding device

Abstract

This utility model relates to the field of welding technology. An embodiment of this utility model provides a welding device for ship steel plates, including a workbench. A base is fixedly connected to the bottom of the workbench, and foot pads are fixedly connected to the bottom of the base. A welding device is mounted on the top of the workbench. In this utility model, the operator places the plate to be welded onto the workbench, thereby starting a dual-output shaft motor. Its two output shafts rotate synchronously, driving two active power gears to rotate. Because the number of teeth on the active power gear is less than the number of teeth on the driven power gear, the driven power gear rotates at a slower speed. This gear ratio design allows the threaded rod to rotate slowly and stably. As the threaded rod rotates, the threaded sleeve gradually moves along the circumference of the threaded rod. This technical solution solves the problem of unstable clamping and welding of plates in related technologies.

Description

Technical Field

[0001] The embodiments of this utility model relate to the field of filter technology, and more specifically, to a ship steel plate welding device. Background Technology

[0002] In shipbuilding, steel plate welding is a crucial process. Traditional welding methods often rely on manual operation, which is not only inefficient but also makes it difficult to guarantee weld quality.

[0003] According to a publicly disclosed ship steel plate welding device (publication number: CN105750681B), it includes a nozzle, a rotating shaft, a support frame, a first motor, a support plate, a first base, a first double-headed cylinder, a scissor arm, a second base, a second slide rail, a first gear, a first wheel frame, a base, a welding machine, a second wheel frame, a second motor, a second gear, a third slide rail, a third slider, a controller, a bracket, a rack, a second slider, a second support, a second double-headed cylinder, a first support, a first slide rail, a first slider, a first connecting rod, a first fisheye bearing, a cylinder, a second connecting rod, a second fisheye bearing, and an electric push rod. The base is mounted on the third slide rail, the first wheel frame is mounted on the base, the first gear is mounted on the first wheel frame, and a second gear is mounted to the right of the first gear. The second gear meshes with the first gear and is mounted on the second wheel frame. The advantage of this invention is that it can automatically adjust the nozzle's spray angle and spray height.

[0004] In the aforementioned application, the nozzle angle and height are adjusted through a complex combination and adjustment of multiple components. However, this design not only increases manufacturing costs, but also, in actual operation, the linkage of multiple components is prone to increase the failure rate and affect welding efficiency. Therefore, we propose a ship steel plate welding device. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this utility model provide a ship steel plate welding device, which solves the problem of unstable clamping and welding of steel plates in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a ship steel plate welding device, including a workbench, a base fixedly connected to the bottom of the workbench, a foot pad fixedly connected to the bottom of the base, a welding device provided on the top of the workbench, and a clamping device provided on the top of the workbench.

[0007] The clamping device includes a dual-output shaft motor, which is fixedly connected to the bottom of the worktable. The output shaft of the dual-output shaft motor is fixedly connected to a drive gear. A support plate is rotatably connected to the circumferential surface of the output shaft of the dual-output shaft motor. A sliding groove is provided on the top of the worktable. A threaded rod is rotatably connected through the side of the worktable. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A moving plate is fixedly connected to the circumferential surface of the threaded sleeve. A clamping plate is fixedly connected to the side of the moving plate. A limit post is fixedly connected to the side of the moving plate. A driven gear is fixedly connected to one end of the threaded rod. A limit plate is fixedly connected to the end of the threaded rod away from the driven gear.

[0008] For example, in at least one embodiment of the present invention, a ship steel plate welding device further includes: a reset buffer plate fixedly connected to the top of the workbench, and a reset buffer spring fixedly connected to the side of the reset buffer plate. The number of reset buffer plates and reset buffer springs is four, arranged in pairs and symmetrically along the central axis of the workbench. Their function is to provide buffering when the clamping plate is reset, preventing the clamping plate from damaging the ship steel plate and improving the safety of the ship steel plate welding device.

[0009] The number of teeth on the active power gear is less than the number of teeth on the driven power gear. The driven power gear meshes with the active power gear, thereby effectively clamping ship steel plates of various sizes and improving the practicality and stability of the ship steel plate welding device.

[0010] The side of the movable plate is slidably connected to the inner side of the slide groove. The side cross-section of the movable plate is convex, and the side cross-section of the slide groove is concave. This is to prevent the movable plate from shifting or shaking during the sliding process, thereby further improving the stability and clamping effect of the ship steel plate welding device.

[0011] The clamping plate, the movable plate, and the threaded sleeve are provided in four groups of two, and are symmetrical about each other along the central axis of the workbench. Their function is to stably clamp the two ship steel plates that need to be welded, so as to prevent the ship steel plates from shifting or shaking during the welding process.

[0012] The active power gear, driven power gear, dual-output shaft motor, and slide are provided in two quantities and are symmetrical about each other along the central axis of the worktable. Their function is to enable the synchronous clamping of two ship steel plates that need to be welded together, thereby improving clamping efficiency and stability.

[0013] According to another aspect, at least one embodiment of the present invention also provides a ship steel plate welding device, including a pusher plate device. The pusher plate device is provided at the bottom of the worktable. The pusher plate device includes a pusher plate, which is slidably connected to the top of the worktable. A connecting plate is fixedly connected to the side of the pusher plate. A rack is fixedly connected to the bottom of the connecting plate. A drive gear is fixedly connected to the end of the dual-output shaft motor away from the drive power gear. A through slot is provided on the top of the worktable to facilitate pushing the ship steel plate to be welded into the slot, further improving the automation level and practicality of the ship steel plate welding device.

[0014] For example, in a ship steel plate welding device provided in at least one embodiment of the present invention, a propulsion buffer spring is fixedly connected to the side of the through groove, and a propulsion buffer plate is fixedly connected to the end of the propulsion buffer spring away from the worktable. Its function is to prevent damage to the ship steel plate or the device itself, thereby further improving the safety and stability of the ship steel plate welding device.

[0015] The side of the propulsion buffer plate is located on the displacement trajectory of the rack side. There are two propulsion buffer plates and two propulsion buffer springs, which are symmetrical about each other along the central axis of the worktable. Their function is to avoid damage to the ship's steel plate due to excessive thrust, and at the same time improve the stability of the device.

[0016] The drive gear meshes with the rack, and the side of the rack is slidably connected to the inner side of the through groove. The side of the connecting plate is also slidably connected to the inner side of the through groove. This increases the stability during movement and prevents it from shifting or shaking.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] 1. In this utility model, the stable clamping of ship steel plates is achieved through the cooperation of components such as the dual-output shaft motor, the drive gear, and the support plate in the clamping device. Furthermore, the difference in the number of teeth between the drive gear and the driven gear allows the threaded rod to drive the clamping plate to move over a wide range, thus adapting to ship steel plates of different sizes and greatly improving the practicality and flexibility of the device. Simultaneously, the design of the reset buffer plate and reset buffer spring not only provides cushioning during clamping plate reset to prevent damage to the ship steel plates but also improves the safety of the device to a certain extent.

[0019] 2. In this utility model, the automated pushing of ship steel plates is achieved through the cooperation of components such as the push plate, connecting plate, and rack in the push plate device, greatly saving manpower and improving welding efficiency. The meshing design of the drive gear and rack allows the push plate to move smoothly and precisely, avoiding damage to the ship steel plates caused by shaking during the pushing process. The design of the propulsion buffer spring and propulsion buffer plate further enhances the safety and stability of the device, protecting the ship steel plates and the device itself from damage even if resistance is encountered during the pushing process through the buffering effect.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5As shown, a ship steel plate welding device according to an embodiment of the present invention is shown, including a workbench 1, a base 2 fixedly connected to the bottom of the workbench 1, a foot pad 3 fixedly connected to the bottom of the base 2, a welding device 4 provided on the top of the workbench 1, and a clamping device 5 provided on the top of the workbench 1.

[0034] The clamping device 5 includes a dual-output shaft motor 501, which is fixedly connected to the bottom of the worktable 1. The output shaft of the dual-output shaft motor 501 is fixedly connected to a drive gear 502. A support plate 503 is rotatably connected to the circumferential surface of the output shaft of the dual-output shaft motor 501. A sliding groove 504 is provided on the top of the worktable 1. A threaded rod 505 is rotatably connected through the side of the worktable 1. A threaded sleeve 506 is threadedly connected to the circumferential surface of the threaded rod 505. A moving plate 507 is fixedly connected to the circumferential surface of the threaded sleeve 506. A clamping plate 508 is fixedly connected to the side of the moving plate 507. A limit post 509 is fixedly connected to the side of the moving plate 507. A driven gear 510 is fixedly connected to one end of the threaded rod 505. A limit plate 511 is fixedly connected to the end of the threaded rod 505 away from the driven gear 510.

[0035] In some examples, the following are also included: a reset buffer plate 6 is fixedly connected to the top of the workbench 1, and a reset buffer spring 7 is fixedly connected to the side of the reset buffer plate 6. The number of reset buffer plates 6 and reset buffer springs 7 is set to four, in pairs, and symmetrical to each other along the central axis of the workbench 1. Their function is to provide buffer when the reset buffer plate 508 is reset, to prevent the clamping plate 508 from damaging the ship steel plate, and to improve the safety of the ship steel plate welding device.

[0036] The number of teeth of the driving gear 502 is less than that of the driven gear 510. The driven gear 510 meshes with the driving gear 502, which effectively clamps ship steel plates of various sizes, thereby improving the practicality and stability of the ship steel plate welding device.

[0037] The side of the movable plate 507 is slidably connected to the inner side of the slide groove 504. The side cross section of the movable plate 507 is set in a convex shape, and the side cross section of the slide groove 504 is set in a concave shape. The purpose of this is to prevent the movable plate 507 from shifting or shaking during the sliding process, thereby further improving the stability and clamping effect of the ship steel plate welding device.

[0038] The number of clamping plates 508, moving plates 507 and threaded sleeves 506 is set to four, in pairs, and symmetrical to each other along the central axis of the worktable 1. Their function is to stably clamp the two ship steel plates to be welded, and to prevent the ship steel plates from shifting or shaking during the welding process.

[0039] The active power gear 502, the driven power gear 510, the dual-output shaft motor 501, and the slide 504 are arranged in two ways and are symmetrical about each other along the central axis of the worktable 1. Their function is to enable the synchronous clamping of two ship steel plates that need to be welded together, thereby improving clamping efficiency and stability.

[0040] For example, such as Figures 1-5 As shown, the worker places the plate to be welded onto the workbench 1, thereby starting the dual-output shaft motor 501. Its two output shafts rotate synchronously, driving the two drive gears 502 to rotate. Because the number of teeth in the drive gear 502 is less than that in the driven gear 510, the driven gear 510 rotates at a slower speed. This gear ratio design allows the threaded rod 505 to rotate slowly and stably. As the threaded rod 505 rotates, the threaded sleeve 506 gradually moves along the circumference of the threaded rod 505, thereby pushing the moving plate 507 to slide within the groove 504. Because the side cross-section of the moving plate 507 is convex and the side cross-section of the groove 504 is concave, this design ensures the stability of the moving plate 507 during sliding, preventing offset or wobbling. As the moving plate 507 moves, the two clamping plates 508 also move closer to the center of the workbench 1 until they tightly clamp the ship steel plate placed on the workbench 1. Meanwhile, the limiting post 509 restricts the travel of the moving plate 507 during movement, preventing it from moving excessively and damaging the device. Once the ship's steel plates are stably clamped, the welding device 4 can begin to work and weld the two ship's steel plates.

[0041] like Figures 1-5 As shown, this invention illustrates a ship steel plate welding device in another embodiment of the present invention. It is largely the same as the technical solution described above, so only the differences are emphasized. A pusher plate device 8 is provided at the bottom of the workbench 1. The pusher plate device 8 includes a pusher plate 801, which is slidably connected to the top of the workbench 1. A connecting plate 802 is fixedly connected to the side of the pusher plate 801, and a rack 803 is fixedly connected to the bottom of the connecting plate 802. A drive gear 804 is fixedly connected to the end of the dual-shaft motor 501 away from the drive gear 502. A through slot 805 is provided on the top of the workbench 1, which facilitates pushing the ship steel plate to be welded into the slot, further improving the automation and practicality of the ship steel plate welding device.

[0042] In some examples, a propulsion buffer spring 9 is fixedly connected to the side of the through groove 805, and a propulsion buffer plate 10 is fixedly connected to the end of the propulsion buffer spring 9 away from the worktable 1. Its function is to prevent damage to the ship steel plate or the device itself, thereby further improving the safety and stability of the ship steel plate welding device.

[0043] The side of the propulsion buffer plate 10 is located on the displacement trajectory of the side of the rack 803. There are two propulsion buffer plates 10 and two propulsion buffer springs 9, which are symmetrical about each other along the central axis of the worktable 1. Their function is to avoid damage to the ship's steel plate due to excessive thrust, and at the same time improve the stability of the device.

[0044] The drive gear 804 meshes with the rack 803. The side of the rack 803 is slidably connected to the inner side of the through groove 805. The side of the connecting plate 802 is slidably connected to the inner side of the through groove 805. This increases the stability during movement and prevents it from shifting or shaking.

[0045] For example, such as Figures 1-5 As shown, when the dual-output shaft motor 501 operates, its end furthest from the drive gear 502 drives the drive gear 804 to rotate. Since the drive gear 804 meshes with the rack 803, the rack 803 moves with the rotation of the drive gear 804. The movement of the rack 803 causes the connecting plate 802 and the push plate 801, which is fixedly connected to it, to slide on the top of the worktable 1. This automatically pushes the ship steel plate to be welded into the welding position, further improving the automation of the welding process. Simultaneously, the design of the through slot 805 provides sufficient space for the movement of the push plate 801, connecting plate 802, and rack 803, ensuring their stability during movement.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
