Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator stator processing technology, and in particular to a generator stator welding device. Background Technology
[0002] The stator is an important component of a generator. It consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate current, thus enabling the generator to work normally. In order to ensure that the generator can be used normally, the stator windings, the frame, and the core assembly need to be welded together to ensure that the stator can work normally.
[0003] Chinese patent application publication number CN221935739U discloses a motor stator welding device, including a welding table. A fixed platform is fixedly mounted on the top of the welding table. A first motor is fixedly mounted inside the welding table, and a lead screw is fixedly mounted on the output shaft of the first motor. A threaded sleeve is threadedly connected to the outside of the lead screw, and a hinge rod is hinged to the outside of the threaded sleeve. A movable groove is formed on the top of the fixed platform, and a fixed rod is fixedly mounted inside the movable groove. A movable block is movably mounted outside the fixed rod, and a clamping plate is fixedly mounted on the top of the movable block. A slot is formed at the center of the fixed platform. While this device clamps and fixes the stator, the position of the welding torch can be adjusted by rotating the threaded rod and moving the threaded block, allowing welding only to positions along a straight line. However, since stators are generally circular, welding to positions outside this straight line requires first unfixing the stator, then manually adjusting and fixing it again before welding can proceed. This makes stator welding cumbersome and detrimental to the device's usability. Utility Model Content

[0020] Reference Figure 1-4A generator stator welding device includes a base 1, a rotating assembly at the bottom of the base 1, a first gear 4 at the top of the base 1 via the rotating assembly, a second gear 5 meshing with the surface of the first gear 4, a worktable 6 fixedly mounted inside the second gear 5, and the worktable 6 rotatably connected to the base 1. The rotating assembly includes a first motor 2 at the bottom of the base 1, the output end of the first motor 2 extending through the base 1 to the top of the base 1 and fixedly mounted with a rotating shaft 3, which is fixedly connected to the first gear 4. The rotating assembly facilitates the provision of driving force for the rotation of the first gear 4, allowing the worktable 6 to rotate and thus facilitating the adjustment of the stator welding position. A driving assembly is located at the bottom of the worktable 6, and a first screw 11 is mounted at the bottom of the worktable 6 via the driving assembly. A fixing plate 12 is rotatably connected to the surface of the first screw 11, and the fixing plate 12 is fixedly connected to the worktable 6, facilitating more stable rotation of the first screw 11. A threaded movable rod 13 is connected to a worktable 6. A clamping block 14 is fixedly installed on the top of the movable rod 13. A movable component is provided on the top of the base 1. An electric push rod 19 is provided on the top of the base 1 through the movable component. A welding gun 20 is fixedly installed at the output end of the electric push rod 19. Support legs 21 are fixedly installed at the bottom of the base 1. There are multiple support legs 21. This generator stator welding device uses a drive component to make four first screws 11 rotate simultaneously, causing the four movable rods 13 to drive the clamping block 14 to move towards the center and clamp and fix the stator. A rotation component makes the first gear 4 rotate, causing the second gear 5 to rotate, causing the worktable 6 to rotate, and causing the stator to rotate. The left and right positions of the welding gun 20 can be adjusted by the movable component, so that the welding gun 20 can weld the stator more comprehensively. All welding on the top of the stator can be completed without removing the fixation of the stator. The operation is simple and reduces the time required for welding the stator.
[0021] according to Figure 4 As shown, the drive assembly includes a support frame 7 located at the bottom of the workbench 6, a second motor 8 at the bottom of the inner wall of the support frame 7, a first bevel gear 9 fixedly mounted at the output end of the second motor 8, a second bevel gear 10 meshing with the surface of the first bevel gear 9, and the second bevel gear 10 fixedly connected to the first screw 11. The drive assembly allows the first screw 11 to rotate simultaneously, thereby facilitating the synchronous approach or distance of the four clamping blocks 14.
[0022] according to Figure 2As shown, the moving assembly includes a fixed frame 15 disposed on the top of the base 1. A third motor 16 is fixedly installed on the right side of the fixed frame 15. The output end of the third motor 16 extends through the fixed frame 15 into the interior of the fixed frame 15 and is fixedly installed with a second screw 17. The second screw 17 is a bidirectional threaded rod made of stainless steel. A moving plate 18 is threadedly connected to the surface of the second screw 17. The moving plate 18 is slidably connected to the fixed frame 15 and fixedly connected to the electric push rod 19. By setting up the moving assembly, it is convenient to adjust the left and right positions of the electric push rod 19 and the welding gun 20. When encountering symmetrical welding points, the welding gun 20 can weld the stator simultaneously, thereby completing the welding of the stator faster.
[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.
[0024] In use: The stator is placed on the workbench 6. The second motor 8 causes the first bevel gear 9 to rotate, which in turn causes the second bevel gear 10 to rotate, which in turn causes the first screw 11 to rotate. This causes the moving rod 13 and the clamping block 14 to move together toward the center, so that the clamping block 14 clamps and fixes the stator. Then, the first motor 2 causes the rotating shaft 3 to rotate, which in turn causes the first gear 4 to rotate, which in turn causes the second gear 5 to rotate, which causes the workbench 6 to rotate, and the stator to rotate to the appropriate position. Then, the third motor 16 causes the second screw 17 to rotate, which causes the moving plates 18 to move relative to each other, so that the electric push rod 19 and the welding gun 20 move to the appropriate position. Then, the electric push rod 19 causes the welding gun 20 to move downward to the appropriate position, so that the welding gun 20 welds the stator.
