[0023] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.
[0024] like Figure 1-4 As shown, this utility model provides a rotatable welding device, comprising:
[0025] A fixed base 1 is provided with a support frame 2, and the support frame 2 is provided with a welding assembly that can move up and down relative to it;
[0026] The clamping mechanism includes two annular fixed disks 3 rotatably connected to the fixed base 1. The two fixed disks 3 are arranged in parallel, and the welding assembly can move downward between the two fixed disks 3. The inner ring of the fixed disk 3 is provided with a bidirectional lead screw 16. The bidirectional lead screw 16 is provided with two bases 17 that can move relative to or away from each other. The bases 17 are provided with U-shaped clamping plates 18 to clamp the welding material. The bottom end of the clamping plate 18 is slidably connected to the fixed disk 3. The two fixed disks 3 are connected to a first driving assembly to drive the two fixed disks 3 to rotate.
[0027] In this technical solution, the fixed base 1 provides a supporting foundation for the entire device. It is usually made of welded metal plates or profiles and has sufficient strength and stability. The support frame 2 is vertically mounted on the fixed base 1 and is used to install and support the welding assembly and clamping mechanism. The welding assembly includes welding tools such as the welding gun 14. It can move up and down along the support frame 2 by means of a slider cooperating with the guide rail on the support frame 2, and its position can be adjusted by means of a motor, lead screw or cylinder. The two ends of the bidirectional lead screw 16 are supported on the inner ring of the fixed plate 3 by bearings. The base 17 and the clamping plate 18 are fixed by bolts or welding. The welding assembly can move not only up and down but also left and right. The central axis of the fixed plate 3 is set horizontally, and the bidirectional lead screw 16 is set horizontally. The base 17 has a through hole, and the inner wall of the through hole is provided with a thread corresponding to the bidirectional lead screw 16 so as to drive the clamping plate 18 to move through the bidirectional lead screw 16. The inner ring of the fixed plate 3 is provided with a second rotary motor 24. The output shaft of the second rotary motor 24 is connected to a first pulley 21. The bidirectional lead screw 16 is coaxially provided with a second pulley 22. The first pulley 21 and the second pulley 22 are connected by a belt 23.
[0028] During use, the welding material to be welded is fixed by two clamping plates 18. After welding is completed on one side, the first drive component drives the fixed disk 3 to rotate, thereby achieving the welding of the material.
[0029] By adopting this technical solution, the present invention can fix and rotate the welding material by setting a fixing plate and a clamping plate 18, thereby adjusting the welding position and angle without frequent manual adjustment of the workpiece, thus improving welding efficiency; by setting a clamping plate 18 that can move relative to or away from each other, it can firmly clamp welding materials of different sizes, and the welding component is set with an up-and-down movement function to facilitate adjustment of the position of the welding component.
[0030] In another technical solution, the clamping mechanism includes a first telescopic motor 10 (the telescopic direction of the first telescopic motor 10 is vertical) mounted on the support frame 2. The end of the output shaft of the first telescopic motor 10 is connected to a positioning plate 11 (the positioning plate 11 is horizontally arranged). The positioning plate 11 is provided with a first slide rail (the first slide rail is horizontally arranged). A first slider is slidably mounted on the first slide rail. The positioning plate 11 is provided with a second telescopic motor 13 (the telescopic direction of the second telescopic motor 13 is horizontal). The end of the output shaft of the second telescopic motor 13 is connected to the first slider to drive the first slider to move along the first slide rail. The first slider is provided with a support block 12. The support block 12 is provided with a welding torch 14 and an inert gas box. The inert gas box is connected to an air inlet and an air outlet. An air outlet pipe is connected to the air outlet. The end of the air outlet pipe sprays air towards the welding torch 14. The first telescopic motor 10 is fixed to the support frame 2 by bolts or a connecting frame. Its output shaft is vertically downward and connected to the top center of the positioning plate 11, driving the positioning plate 11 to move up and down. The first slide rail is horizontally mounted on the bottom surface of the positioning plate 11, and the first slider slides in cooperation with the first slide rail. The second telescopic motor 13 is mounted parallel to the first slide rail on the positioning plate 11, and its output shaft is connected to the first slider via a coupling or connecting block. When the second telescopic motor 13 operates, it pushes the first slider to move linearly along the first slide rail. The support block 12 is fixed to the bottom of the first slider, and the welding torch 14 is mounted on one side of the support block 12 via a clamp or bolts. The inert gas box is mounted on the other side of the support block 12. The air inlet is connected to the inert gas source via a pipe, and the air outlet is connected to one end of the air outlet pipe. The other end of the air outlet pipe is bent and faces the welding end of the welding torch 14, allowing the inert gas to protect the weld in a timely manner during the welding process. Using this technical solution, through the coordinated operation of the first telescopic motor 10 and the second telescopic motor 13, the welding torch 14 can be adjusted in both vertical and horizontal directions, improving the flexibility and adaptability of welding. Meanwhile, the inert gas chamber and exhaust pipe enable the continuous injection of inert gas into the welding area during the welding process, effectively preventing weld oxidation and improving welding quality and strength.
[0031] In another technical solution, the fixed disk 3 is coaxially provided with an annular second slide rail 5, and two second sliders 6 are slidably provided on the second slide rail 5;
[0032] The fixed base 1 is provided with two pairs of support rods 7, which correspond one-to-one with two fixed disks 3. Two support rods 7 in each pair are fixedly connected to two second sliders 6 to achieve a rotatable connection between the fixed disk 3 and the fixed base 1. An annular second slide rail 5 is fixed to the surface of the fixed disk 3 by bolts or welding, maintaining coaxiality with the fixed disk 3; the second sliders 6 slide in conjunction with the second slide rail 5. Using this technical solution, the present invention achieves a rotatable connection between the fixed disk 3 and the fixed base 1 through the combined structure of the annular second slide rail 5, the second sliders 6, and the support rods 7, ensuring the stability and reliability of the fixed disk 3 during rotation. This structural design effectively supports the weight of the fixed disk 3, its clamping mechanism, and the welding material, while allowing the fixed disk 3 to rotate smoothly under the drive of the first drive assembly, providing a fundamental guarantee for multi-angle welding.
[0033] In another technical solution, the fixed disk 3 is provided with a plurality of meshing teeth 4 at intervals on its outer circumference;
[0034] The first drive assembly includes two first gears 9 that mesh with meshing teeth 4 on two fixed disks 3 respectively (the two first gears 9 are arranged one-to-one with the two fixed disks 3). The first gears 9 are rotatably connected to the fixed base 1. A drive shaft 26 is connected between the two first gears 9. A second gear is mounted on the drive shaft 26. A bracket 27 is provided on the support frame 2. A first rotary motor 28 is mounted on the bracket 27. A third gear is connected to the first rotary motor 28. The third gear meshes with the second gear to drive the first gears 9 to rotate. The outer circumferential surface of the fixed disk 3 is machined with multiple evenly distributed meshing teeth 4 to form a gear-like structure. The two ends of the drive shaft 26 are fixedly connected to the centers of the two first gears 9 respectively to ensure that the two first gears 9 rotate synchronously. The second gear is fixed in the middle position of the drive shaft 26 and rotates synchronously with the drive shaft 26. The bracket 27 is fixed to the support frame 2 by bolts or welding. The first rotary motor 28 is mounted on the bracket 27, and its output shaft is connected to the third gear. The third gear meshes with the second gear. When the first rotary motor 28 operates, it drives the third gear to rotate. The third gear then drives the second gear and the drive shaft 26 to rotate through meshing transmission, thereby driving the two first gears 9 to rotate synchronously, ultimately achieving the rotation of the fixed disk 3. Using this technical solution, through the aforementioned gear transmission structure, the power of the first rotary motor 28 can be reliably transmitted to the fixed disk 3, achieving synchronous rotation of the two fixed disks 3. Gear transmission has advantages such as high transmission efficiency, accurate transmission ratio, and reliable operation, ensuring the stability and precision of the fixed disk 3 during rotation, thus providing a stable angle adjustment function for the welding process and improving welding quality and efficiency.
[0035] In another technical solution, the fixed base 1 is provided with two columns 8 (vertically arranged), and each column 8 is provided with a fixed shaft 25. The two fixed shafts 25 are rotatably connected to two first gears 9 to achieve a rotatable connection between the first gears 9 and the fixed base 1. The columns 8 are usually made of metal tubing or profiles and are fixed to the fixed base 1 by welding or bolting. The fixed shafts 25 are horizontally installed at the top of the columns 8 and can be connected to the columns 8 by interference fit, key connection, or bolt fixing. A bearing is installed in the center hole of the first gear 9. The inner ring of the bearing is tightly fitted with the fixed shaft 25, and the outer ring is tightly fitted with the center hole of the first gear 9. With this structure, the first gear 9 can rotate freely around the fixed shaft 25 to achieve a rotatable connection with the fixed base 1. To ensure the axial positioning of the first gear 9, a shoulder can be provided at the end of the fixed shaft 25 or a limiting nut can be installed to prevent the first gear 9 from moving axially during rotation. By adopting this technical solution, this utility model provides a stable rotational support structure for the first gear 9 through the arrangement of the columns 8 and the fixed shafts 25. This structural design is simple and reliable, and can effectively ensure the stability and accuracy of the first gear 9 during rotation, thereby ensuring that the first drive assembly can reliably transmit power to the fixed disk 3, realize the smooth rotation of the fixed disk 3, and provide a stable working platform for welding operations.
[0036] In another technical solution, the fixed disk 3 (inner ring) is provided with a connecting plate, which is parallel to the bidirectional lead screw 16. A third slide rail is mounted on the connecting plate, and two third sliders slide on the third slide rail. Each third slider is connected to one of the two clamping plates 18. The connecting plate is typically made of metal sheet and is fixed to the inner ring surface of the fixed disk 3 by bolts or welding, remaining parallel to the bidirectional lead screw 16. The third slide rail is installed on the top of the connecting plate along its length, and the third sliders slide in cooperation with the third slide rail. Each third slider is connected to the bottom end of the corresponding clamping plate 18 by bolts or welding. When the bidirectional lead screw 16 rotates and drives the base 17 to move, the clamping plate 18 moves accordingly. Simultaneously, the third sliders slide on the third slide rail, providing additional support and guidance for the movement of the clamping plate 18, ensuring smooth movement. Using this technical solution, the present invention enhances the stability and guidance of the clamping plate 18 during movement through the arrangement of the connecting plate, the third slide rail, and the third sliders. This structural design effectively prevents the clamping plate 18 from tilting or wobbling during movement, ensuring that the clamping plate 18 can move accurately relative to or away from each other, thereby achieving reliable clamping of the welding material and improving the stability and reliability of the welding process.
[0037] In another technical solution, the clamping plate 18 has multiple threaded holes spaced apart along its length on its upper horizontal edge. Each threaded hole contains a positioning rod 20 with external threads. The lower ends of the multiple positioning rods 20 on the same clamping plate 18 are connected to an adjusting plate 19. The adjusting plate 19 is rotatably connected to the positioning rods 20 (one implementation could be: the adjusting plate 19 has multiple annular fifth slide rails, each fifth slide rail has two symmetrically arranged fifth sliders, multiple second slide rails 5 correspond one-to-one with multiple positioning rods 20, and the fifth sliders are connected to the bottom ends of the positioning rods 20). The adjusting plate 19 is parallel to the bottom surface of the clamping plate 18. Multiple threaded holes are uniformly machined along the length of the upper horizontal edge of the clamping plate 18, and the axes of the threaded holes are perpendicular to the bottom surface of the clamping plate 18. The external threads of the positioning rods 20 match the threaded holes and can be screwed into them. By rotating the positioning rod 20, its extension length within the threaded hole can be adjusted, thereby causing the adjusting plate 19 to move up and down, adjusting the distance between the adjusting plate 19 and the bottom surface of the clamping plate 18. Since multiple positioning rods 20 on the same clamping plate 18 are adjusted synchronously, the adjusting plate 19 always remains parallel to the bottom surface of the clamping plate 18. The number of positioning rods 20 can be set to two. Using this technical solution, the position of the adjusting plate 19 can be flexibly adjusted according to the thickness and shape of the welding material through the setting of the positioning rods 20 and the adjusting plate 19. This invention achieves precise clamping and positioning of the welding material. This structural design can adapt to welding materials of different sizes and shapes, improving the versatility and applicability of the welding device. Simultaneously, the parallel arrangement of the adjusting plate 19 and the bottom surface of the clamping plate 18 ensures that the welding material remains horizontal during clamping, which is beneficial for improving welding accuracy and quality.
