Description

Technical Field

[0001] This utility model relates to the field of magnetic pole welding positioner technology, and more specifically, to a drive turntable device for a magnetic pole welding positioner. Background Technology

[0002] The manufacturing of magnetic poles for large generators often requires welding. Due to the unique structure of the magnetic poles, manual flipping and welding are typically used, which is inefficient. Therefore, there is an urgent need to design a positioner suitable for flipping and welding magnetic poles in large generators.

[0003] However, due to the large weight and size of the magnetic poles of large generators, it is not suitable to use the drive turntable of a conventional positioner to rotate them. The main reason is that the large weight and complex structure of the magnetic poles of large generators result in very complex resisting torques from the magnetic poles during the rotation of the drive turntable, which makes the drive turntable of a conventional positioner easily damaged. Therefore, there is an urgent need for a positioner drive turntable device specifically adapted for magnetic pole welding, especially suitable for welding magnetic poles of large generators.

[0039] Specifically, the fixed base 1 can be connected to the column of the magnetic pole welding positioner.

[0040] It should be noted that the driver 4 here can be a servo motor or a hydraulic motor, as long as it can drive the first worm gear reducer 2.

[0041] In this invention, the first worm gear reducer 2 is used as a transmission. The self-locking characteristic of worm gear transmission ensures the safety of driving magnetic pole rotation. Simultaneously, the first worm gear reducer 2 is small in size, minimizing interference with the rotation of the rotating seat 6. Furthermore, the first worm gear reducer 2 has a large transmission ratio, which reduces the output power of the driver 4, addressing the high energy consumption issue of driving the magnetic pole rotation of large generators with heavy loads, thus achieving greater energy savings. Additionally, to address the complex torsional torque exerted by the magnetic poles on the rotating seat 6, a slewing bearing 5 ensures stable rotation of the rotating seat 6 relative to the fixed seat 1 under complex force conditions. Moreover, the slewing bearing 5, with its external gear on the outer ring, serves as the transmission gear 92, saving space in the limited area of ​​the drive turntable. The gear set also ensures accurate and reliable torque transmission.

The back of the opening of the side plate 62 is connected to the base plate 61. The clamp is arranged at the C-shaped opening of the two side plates 62.

[0051] By using the side plates 62 and the base plate 61 to form the rotating seat 6, the weight of the rotating seat 6 can be significantly reduced, thereby reducing drive power consumption. Moreover, the clamps are located at the C-shaped openings of the two side plates 62, which also facilitates the clamping and fixing of the magnetic end parts.

[0052] Furthermore, the rotating seat 6 also includes multiple ribs, which connect the two side plates 62, and the two side plates 62 are spaced apart.
