Description

Technical Field

[0001] This utility model relates to the technical field of welding auxiliary devices, and specifically to a welding auxiliary butt welding fixture. Background Technology

[0002] In modern industrial production, steel structures, with their advantages of high strength, good toughness, and convenient construction, are widely used in many fields such as construction, machinery manufacturing, bridge construction, and aerospace. Steel structure components are mainly composed of steel materials, and common structural forms include circular and square components. These components are mostly connected by welds to form a stable overall structure.

[0003] During welding operations, the shape, size, and material properties of steel structural workpieces often present challenges in achieving precise alignment, leading to frequent deviations. These deviations not only severely impact weld quality but can also significantly reduce the overall structural strength and aesthetic smoothness of the welded workpiece. Therefore, welding auxiliary butt welding fixtures are needed to align two steel structural workpieces to be welded, effectively reducing errors from manual alignment, greatly improving the stability and precision of the welding process, and providing a solid guarantee for achieving high-quality and efficient welding results.

[0004] The inventors discovered in their daily work that welding auxiliary butt welding fixtures still have at least the following problems: Existing welding auxiliary butt welding fixtures often only meet the welding requirements of standard angles (such as 45 degrees, 90 degrees, 180 degrees, etc.), and are inadequate for welding non-standard angles. Due to the lack of a flexible angle adjustment mechanism, these fixtures cannot preset and lock specific non-standard angles according to actual needs, thus limiting their application range in welding complex structures. Utility Model Content

[0005] This utility model provides a welding auxiliary butt welding fixture, which can solve the problem that existing welding auxiliary butt welding fixtures lack corresponding preset angle adjustment functions when it is necessary to weld steel structure workpieces at a specific non-standard angle.

[0006] A welding auxiliary butt welding fixture includes a base, a turntable, and a clamping mechanism. The turntable is rotatably connected to the base. The clamping mechanism has two sets, namely a first clamping component and a second clamping component. The first clamping component is fixedly connected to the base, and the second clamping component is fixedly connected to the turntable. The base is provided with an angle adjustment mechanism for adjusting the rotation angle of the turntable, and the turntable is provided with a slag collection mechanism for collecting slag.

[0007] According to one embodiment of the present invention, the clamping mechanism includes a mounting frame, a support frame, and a movable pressure plate. The support frame is fixedly connected to the mounting frame, and a horizontal sliding groove is provided at the bottom of the support frame. The movable pressure plate is slidably disposed in the sliding groove.

[0008] According to one embodiment of the present invention, the clamping mechanism further includes an adjusting screw and an adjusting sleeve. The adjusting sleeve is fixedly disposed horizontally on the side of the support frame. One end of the adjusting screw is rotatably connected to the movable pressure plate, and the other end of the adjusting screw is disposed through the adjusting sleeve and threadedly connected to the adjusting sleeve.

[0009] According to one embodiment of the present invention, the clamping mechanism further includes an adjusting handwheel, which is coaxially and fixedly connected to the adjusting lead screw.

[0010] According to one embodiment of the present invention, the clamping mechanism further includes an elastic pad, which is fixedly disposed on the side of the movable pressure plate.

[0011] According to one embodiment of the present invention, the angle adjustment mechanism includes a driven gear and a driving gear. The turntable has a cylindrical structure. The driven gear is coaxially fixedly connected to the turntable. The driving gear is rotatably connected to the base, and the driven gear meshes with the driving gear.

[0012] According to one embodiment of this utility model, the angle adjustment mechanism further includes a limiting bracket, a locking sleeve, a locking screw, a locking handwheel, and an elastic pressure pad. The limiting bracket is fixedly connected to the base. The locking sleeve is vertically fixedly connected to the limiting bracket and is located above the drive gear. The locking screw is threadedly disposed inside the locking sleeve and is threadedly connected to the locking screw. The locking handwheel is coaxially fixedly connected to the locking screw and is located at the top end of the locking screw. The elastic pressure pad is fixedly connected to the locking screw and is located at the bottom end of the locking screw.

[0013] According to one embodiment of the present invention, the slag collection mechanism includes a collection frame, which is fixedly installed on the top of the turntable.

[0014] The advantages of this utility model compared to the prior art are:

[0015] The angle adjustment mechanism allows for the preset and locking of any non-standard angle according to actual needs, greatly expanding the application range of the tooling in welding complex structures and meeting diverse industrial production requirements. Precise angle adjustment and stable workpiece clamping reduce welding defects caused by workpiece angle deviations and unstable fixing, improving the quality of welded joints and ensuring the stability and reliability of the welded structure.

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] like Figures 1 to 4As shown, a welding auxiliary docking fixture includes a base 1, a turntable 2, and a clamping mechanism 3. The turntable 2 is rotatably connected to the base 1. The clamping mechanism 3 is provided with two sets, namely a first clamping component 4 and a second clamping component 5. The first clamping component 4 is fixedly connected to the base 1, and the second clamping component 5 is fixedly connected to the turntable 2. The base 1 is provided with an angle adjustment mechanism 6 for adjusting the rotation angle of the turntable 2, and the turntable 2 is provided with a slag collection mechanism 7 for collecting slag.

[0026] Specifically, the turntable 2 is connected to the base 1 via a rotatable connection, allowing it to rotate freely within a certain range. The first clamping assembly 4 is fixed to the base 1 and is used to clamp one workpiece to be welded. The second clamping assembly 5 is fixed to the turntable 2 and is used to clamp another workpiece to be welded.

[0027] The user adjusts the rotation angle of the turntable 2 using the angle adjustment mechanism 6 according to welding requirements. Once the desired angle is reached, the angle adjustment mechanism 6 locks the turntable 2, ensuring the angle remains stable during welding. The workpieces to be welded are fixed to the first clamping assembly 4 and the second clamping assembly 5, respectively. After angle adjustment and workpiece clamping are completed, the welding operator can begin welding. Due to the flexibility of the turntable 2 and clamping mechanism 3, welding operations can adapt to the welding needs of various complex structures. During welding, the generated slag and spatter are collected by the slag collection mechanism 7. This helps maintain a clean work area and reduces cleaning work.

[0028] The angle adjustment mechanism 6 allows for the preset and locking of any non-standard angle according to actual needs, greatly expanding the application range of the tooling in welding complex structures and meeting diverse industrial production requirements. Precise angle adjustment and stable workpiece clamping reduce welding defects caused by workpiece angle deviations and unstable fixing, improving the quality of welded joints and ensuring the stability and reliability of the welded structure. The slag collection mechanism 7 effectively collects welding slag, preventing slag from scattering and polluting the work area, while also reducing damage to the tooling and welding equipment, extending equipment lifespan, and improving the working environment.

[0029] In some specific embodiments, the clamping mechanism 3 includes a mounting frame 8, a support frame 9, a movable pressure plate 10, an adjusting screw 11, an adjusting sleeve 12, an adjusting handwheel 13, and an elastic pad 14. The support frame 9 is fixedly connected to the mounting frame 8. A horizontal groove is formed at the bottom of the support frame 9, and the movable pressure plate 10 is slidably disposed within the groove. The adjusting sleeve 12 is fixedly disposed horizontally on the side of the support frame 9. One end of the adjusting screw 11 is rotatably connected to the movable pressure plate 10, and the other end of the adjusting screw 11 passes through the adjusting sleeve 12 and is threadedly connected to the adjusting sleeve 12. The adjusting handwheel 13 is coaxially fixedly connected to the adjusting screw 11. The elastic pad 14 is fixedly disposed on the side of the movable pressure plate 10.

[0030] It should be specifically noted that the mounting bracket 8 in the first clamping assembly 4 is fixedly connected to the base 1, and the mounting bracket 8 in the second clamping assembly 5 is fixedly connected to the turntable 2.

[0031] The adjustment screw 11 rotates within the adjusting sleeve 12, causing the movable pressure plate 10 to move along the slide groove, thereby clamping or releasing the workpiece. The adjusting handwheel 13 is coaxially fixed with the adjusting screw 11, allowing the operator to manually rotate the adjusting screw 11. The elastic pad 14 is fixed to the side of the movable pressure plate 10, providing cushioning protection when clamping the workpiece.

[0032] The clamping mechanism 3 can accommodate workpieces of different sizes. The clamping force can be adjusted by adjusting the screw 11 and the adjusting sleeve 12 through a threaded connection, making operation simple. The adjustment handwheel 13 further enhances the convenience of operation and reduces the labor intensity of workers. The elastic pad 14 can prevent the workpiece surface from being damaged by clamping and protect the surface quality of the workpiece.

[0033] In some specific embodiments, the angle adjustment mechanism 6 includes a driven gear 15, a driving gear 16, a limiting bracket 17, a locking sleeve 18, a locking screw 19, a locking handwheel 20, and an elastic pressure pad 21. The turntable 2 has a cylindrical structure. The driven gear 15 is coaxially and fixedly connected to the turntable 2. The driving gear 16 is rotatably connected to the base 1, and the driven gear 15 meshes with the driving gear 16. The limiting bracket 17 is fixedly connected to the base 1. The locking sleeve 18 is vertically fixedly connected to the limiting bracket 17 and is located above the driving gear 16. The locking screw 19 is threadedly connected to the locking sleeve 18. The locking handwheel 20 is coaxially and fixedly connected to the locking screw 19 and is located at the top of the locking screw 19. The elastic pressure pad 21 is fixedly connected to the locking screw 19 and is located at the bottom of the locking screw 19.

[0034] When the drive gear 16 rotates, it drives the driven gear 15 and the turntable 2 to rotate through gear meshing, thereby adjusting the angle. Rotating the locking handwheel 20 moves the locking screw 19 up and down. The elastic pad 21 at the bottom of the locking screw 19 can press or release the drive gear 16, thus locking or unlocking the angle. The gear transmission provides stable and precise angle adjustment, enabling continuous and smooth angle changes. The locking sleeve 18, locking screw 19, locking handwheel 20, and elastic pad 21 reliably lock the angle after adjustment, preventing the turntable 2 from rotating due to external forces during welding, ensuring the stability of the welding angle, and improving welding accuracy.

[0035] In some specific implementations, the slag collection mechanism 7 includes a collection frame 22, which is fixedly installed on the top of the turntable 2. During the welding process, as the turntable 2 rotates, the collection frame 22 moves accordingly, which can collect welding slag in a timely and effective manner, keep the tooling and working area clean, reduce the potential impact of slag on welding quality, and at the same time reduce the difficulty and frequency of cleaning work, thereby improving work efficiency.

[0036] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
