[0001] This utility model relates to the field of welding auxiliary equipment technology, and in particular to a frame welding base bracket. Background Technology
[0002] like Figure 1 The structural component to be welded, placed within the structure, includes two side rods 9, with a pair of central crossbars 90 welded to each end of the side rods 9. Support legs 91 are also welded at the locations of the side rods 9 and the central crossbars 90. This structural component forms the internal frame of a device's base and is characterized by its significant overall weight. Conventional welding methods involve placing the component on a welding table. To ensure welding quality, the component's orientation needs to be adjusted multiple times to complete the welding operation. Its considerable weight further complicates the welding process. Utility Model Content
[0003] This utility model provides a frame welding base bracket to overcome the shortcomings of the prior art, solve the problem of high welding difficulty, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A frame welded base bracket includes a base plate, side plates formed by bending upwards on both sides of the base plate, protrusions formed at both ends of the side plates, a pivot shaft rotatably provided at the front end of the protrusion, a concave pivot plate welded to the inner end of the pivot shaft, a support plate welded to the concave pivot plate, a plurality of limiting strips welded to the support plate, extension arms formed on both sides of the support plate, a limiting inner plate fixed to the outer end of the extension arm by screws, a pair of transverse holes provided at the outer end of the extension arm, a moving rod passing through the transverse holes, an inner pressure plate connected to the outer end of the moving rod by threads, the inner pressure plate being located outside the limiting inner plate.
[0005] Furthermore, the other end of the moving rod is connected to an inner push plate via a thread. The inner push plate has an oblong hole, the length of which is parallel to the width of the outstretched arm. The outer end of the outstretched arm is rotatably provided with a rotating end shaft. The lower end of the rotating end shaft is fixed to an inner top arm via a pin. The inner end of the inner top arm is connected to an inner top rod via a thread. The outer circumference of the inner top rod abuts against the inner wall of the oblong hole. The upper end of the rotating end shaft is fixed to a swing arm via a pin. There is an angle between the length of the swing arm and the inner top arm.
[0006] Furthermore, the pallet is bent downward to form a lower convex part, and a guide rod is inserted through the lower convex part. An L-shaped plate is welded to the inner end of the guide rod. Multiple strip holes are opened on the L-shaped plate. The length direction of the strip holes is parallel to the length direction of the L-shaped plate. A swing rod is inserted through the strip holes. A swing plate is welded to the inner end of the swing rod. The other end of the swing plate is fixed to a swing shaft by a pin. The swing shaft is rotatably mounted on the pallet. The other end of the swing shaft is eccentrically fixed to an eccentric disc by a pin. The eccentric disc and the limiting strip are in a one-to-one correspondence, and the eccentric disc is located above the limiting strip.
[0007] Furthermore, a rotating boss is welded onto the support plate, and a lead screw is rotatably mounted on the rotating boss. An end cap is formed on the outer end of the lead screw, and a limit ring is connected to the lead screw by a pin. The limit ring is located inside the rotating boss, and the lead screw is threaded to the L-shaped plate.
[0008] Furthermore, a rotating protrusion is welded to the lower side of the pallet, and a concave seat is hinged to the lower end of the rotating protrusion via a connecting shaft. A support rod is welded to the other end of the concave seat, and an end crossbar is welded to the other end of the support rod. The axial direction of the end crossbar is perpendicular to the axial direction of the support rod. A pair of limiting plates are welded to the bottom plate, and multiple U-shaped grooves are opened at the upper end of the limiting plates. The end crossbar is inserted into one of the U-shaped grooves.
[0009] Furthermore, a support crossbar is fixed to the rear protrusion by a pair of nuts.
[0010] The advantages of the above technical solution are: This utility model features a rotating support plate that allows for easy support of various components of the structure as needed, and the tilt angle of the support plate can be adjusted as required, thereby facilitating welding operations. During adjustment, the tilt angle of the support plate can be adjusted and locked by rotating the support rod and placing the end crossbar into one of the U-shaped grooves.
[0011] This invention uses a limiting strip and a rotating eccentric disc to fix each crossbar, ensuring that the crossbar will not move during welding. The inner limiting plate and inner pressure plate can fix the side bars, thus ensuring welding accuracy.
[0012] This invention eliminates the problem of obstruction at the welding position, thus eliminating the need to flip the structural components during the welding process and reducing the difficulty of welding. Attached Figure Description

[0019] like Figures 1-5 As shown, a frame welding base bracket includes a base plate 1. Multiple casters are mounted on the underside of the base plate 1 to facilitate the transfer of the entire structure after welding. Side plates 10 are formed by bending upwards on both sides of the base plate 1. Protrusions 11 are formed at both ends of the side plates 10. A pivot 12 is rotatably mounted on the front protrusion 11. A concave pivot plate 13 is welded to the inner end of the pivot 12. A support plate 2 is welded to the concave pivot plate 13. Multiple limiting strips 20 are welded to the support plate 2. Extending arms 21 are formed on both sides of the support plate 2. A limiting inner plate 25 is fixed to the outer end of the extending arms 21 by screws. A pair of transverse holes 22 are opened at the outer end of the extending arms 21. A moving rod 23 passes through the transverse holes 22. An inner pressure plate 24 is threaded to the outer end of the moving rod 23. The inner pressure plate 24 is located outside the limiting inner plate 25.
[0020] The other end of the moving rod 23 is connected to an inner push plate 30 by a thread. The inner push plate 30 has an oblong hole 31. The length direction of the oblong hole 31 is parallel to the width direction of the outward extension arm 21. The outer end of the outward extension arm 21 is rotatably provided with a rotating end shaft 26. The lower end of the rotating end shaft 26 is fixed with an inner top arm 28 by a pin. The inner end of the inner top arm 28 is connected with an inner top rod 29 by a thread. The outer periphery of the inner top rod 29 abuts against the inner wall of the oblong hole 31. The upper end of the rotating end shaft 26 is fixed with a swing arm 27 by a pin. There is an angle between the length direction of the swing arm 27 and the inner top arm 28.
[0021] The support plate 2 is bent downward to form a lower protrusion 39. A guide rod 38 is inserted through the lower protrusion 39. An L-shaped plate 36 is welded to the inner end of the guide rod 38. Multiple strip holes 37 are opened on the L-shaped plate 36. The length direction of the strip holes 37 is parallel to the length direction of the L-shaped plate 36. A swing rod 35 is inserted through the strip holes 37. A swing plate 34 is welded to the inner end of the swing rod 35. The other end of the swing plate 34 is fixed with a swing shaft 32 by a pin. The swing shaft 32 is rotatably mounted on the support plate 2. The other end of the swing shaft 32 is eccentrically fixed with an eccentric disk 33 by a pin. The eccentric disk 33 and the limiting strip 20 are in a one-to-one correspondence, and the eccentric disk 33 is located above the limiting strip 20.
[0022] A rotating boss 40 is welded onto the support plate 2. A lead screw 41 is rotatably mounted on the rotating boss 40. An end cap 42 is formed on the outer end of the lead screw 41. A limiting ring 43 is connected to the lead screw 41 by a pin. The limiting ring 43 is located inside the rotating boss 40. The lead screw 41 is threaded onto the L-shaped plate 36.
[0023] A rotating protrusion 44 is welded to the lower side of the support plate 2. A concave seat 46 is hinged to the lower end of the rotating protrusion 44 via a connecting shaft 45. A support rod 47 is welded to the other end of the concave seat 46. An end crossbar 48 is welded to the other end of the support rod 47. The axial direction of the end crossbar 48 is perpendicular to the axial direction of the support rod 47. A pair of limiting plates 49 are welded to the bottom plate 1. Multiple U-shaped grooves 50 are opened at the upper end of the limiting plates 49. The end crossbar 48 is inserted into one of the U-shaped grooves 50. A support crossbar 14 is fixed to the protrusion 11 at the rear end by a pair of nuts.
[0024] In this embodiment, during welding, the operator places the side rod 9 between the two sets of limiting inner plates 25 and inner pressure plates 24, and then rotates the swing arm 27. The rotation of the swing arm 27 drives the rotating end shaft 26 to rotate, which in turn drives the inner top arm 28 to rotate. When the inner top arm 28 rotates, it acts on the waist-shaped hole 31 through the inner top rod 29 on it, thereby causing the inner push plate 30 and the inner pressure plate 24 to move inward, and causing the inner pressure plate 24 to act on the outside of the side rod 9. In this way, the fixing operation of the side rod 9 is completed to ensure welding accuracy.
[0025] Then, the operator places the middle crossbar 90 on the limiting strip 20 in sequence. After all the middle crossbars 90 are in place, the operator rotates the lead screw 41. When the lead screw 41 rotates, it will drive the L-shaped plate 36 to move along the axial direction of the guide rod 38. When the L-shaped plate 36 moves, it will act on the swing rod 35 through the strip hole 37. As the swing rod 35 moves, it will drive the swing plate 34 to rotate around the swing shaft 32. The rotation of the swing shaft 32 will drive the eccentric disk 33 to rotate, and make the outer periphery of the far end of the eccentric disk 33 abut against the outer wall of the middle crossbar 90, thereby fixing the middle crossbar 90.
[0026] During the welding process, if it is necessary to tilt the pallet 2, lift one end of the pallet 2, then rotate the pallet 2 upwards and rotate the support rod 47, and place the lower end crossbar 48 into one of the U-shaped grooves 50, and then perform the welding operation.
[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
