Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding tool for a stator of a wind turbine generator. Background Art

[0002] The generator stator is one of the key components of the generator. For high-voltage, large-capacity synchronous motors, a rotating magnetic pole structure is used. Since the capacity and voltage of the excitation part are often much smaller than the armature, the armature is installed on the stator and the main magnetic pole is installed on the rotor. The generator stator mainly acts on the rotating magnetic field formed by the rotor to cut the magnetic field to generate voltage. The generator stator is the stationary part of the motor. Its components mainly include iron core, base, coil and other components.

[0003] However, currently when welding the generator stator base, the hollow cylindrical stator is placed flat on an anti-slip roller frame, and the stator base is driven to rotate slowly by a roller with controllable speed. Then the worker welds inside the base with a handheld device. The rotating base allows all the welding points to move to the worker. However, the worker stands inside the rotating base and needs to maintain balance while welding with the handheld device, which greatly consumes physical strength and reduces work efficiency.

[0022] The bracket 3 is T-shaped, and is divided into a crossbar and a vertical bar, the crossbar is inserted in the machine base 21, and the workbench 4 is inserted and installed on the crossbar. The bracket 3 can be fixedly installed on the ground to prevent it from overturning, and the size of the bracket 3 and the workbench 4 are matched.

[0023] The workbench 4 is provided with four cross beams 41 , and adjacent cross beams 41 are provided with the same intervals therebetween. The vertical beams 42 are provided between adjacent cross beams 41 .

[0024] The rollers 43 are symmetrically mounted on the vertical beam 42 , and the rollers 43 and the vertical beam 42 are rotatably mounted.

[0025] The sleeve 44 on the slide bar 5 and the cross beam 41 is fixedly installed, the sleeve 44 is installed at one end of the movable beam 6, the movable beam 6 is rotatably installed through the sleeve 44 and the slide bar 5, and the movable beam 6 and the mounting seat 7 are rotatably installed through a pin shaft.

[0026] One end of the side plate 62 extends to the cross beam 41, and a threaded hole engaged with the bolt 63 is provided at the side plate 62 where the bolt 63 passes through, and the bottom of the bolt 63 abuts against the cross beam 41. The side plate 62 and the connecting beam 61 are installed in a staggered manner, so that one end of the side plate 62 extends to the top of the cross beam 41, and the bolt 63 is rotated appropriately, so that the height between the side plate 62 and the cross beam 41 changes, the inclination angle of the movable beam 6 also changes accordingly, and the height of the welding machine 71 also changes.

[0027] The elliptical block 82 is symmetrically installed, the connecting rod 83 and the elliptical block 82 are fixedly installed, and the rotating rod 84 and the connecting rod 83 are rotatably installed.

When the lever 81 is vertical, the brake pad 85 is away from the fixed beam 8. At this time, the workbench 4 can move freely.

[0028] Working principle: The machine base 21 is placed flat on the anti-slip roller frame 2. The existing machine base 21 rotates with the anti-slip roller frame 2, thereby moving the ring pair to be welded in the machine base 21 to the bottom. Workers do not need to lift the welding machine 71 for welding, but need to hold the welding machine 71 at all times.

[0029] Insert the workbench 4 on the bracket 3. When the workbench 4 is moved, the roller 43 moves along the outer wall of the bracket 3. When the workbench 4 moves to the target working area, the lever 81 is laid flat and the rotating rod 84 is moved downward so that the brake pad 85 is close to the fixed beam 8, so that friction is generated between the two to fix the workbench 4 at this place on the bracket 3. Then, the bolt 63 is appropriately rotated to adjust the distance between the side plate 62 and the cross beam 41, and the inclination angle of the movable beam 6 is changed, thereby changing the height of the mounting seat 7 and the welding machine 71. The mounting seat 7 and the movable beam 6 are rotatably installed. The worker only needs to adjust the welding angle of the welding machine 71 appropriately, and there is no need to hold the welding machine 71 as usual, which greatly saves physical strength.
