Description

Technical Field

[0001] This utility model relates to the field of rotor winding technology, and specifically to a rotor winding frame. Background Technology

[0002] In the production and maintenance of wound rotors, the process of winding enameled wire into a specific shape is called "winding," and then embedding it into the rotor slots is called "embedding." Embedding is a key process in the production and maintenance of wound rotors, and it is generally done manually.

[0003] During the winding process, the rotor is usually placed directly on the workbench, and then the wire is embedded into the winding slot of the rotor. However, the rotor core has through holes of different sizes. The fixed-size support shaft cannot support the rotor core, which will cause the rotor to shift when winding.

[0004] Therefore, it is particularly important to improve the existing rotor winding frame and design a new type of rotor winding frame to solve the above-mentioned technical defects and improve the overall practicality of the rotor winding frame. Utility Model Content

[0005] The purpose of this utility model is to provide a rotor winding frame that, through an overall design, controls the moving sleeve to move closer to the fixed sleeve, thereby enabling the linkage rod to unfold. The unfolded plate can then fit into the through-holes of rotor cores of different sizes, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotor winding frame includes a support foot, an operating table fixedly connected to the top of the support foot, a connecting platform slidably connected inside the operating table, a telescopic rod fixedly connected to the top of the connecting platform, a flat plate fixedly connected to the top of the telescopic rod, a placement frame fixedly connected to the top of the flat plate, a placement groove with a V-shaped structure on the top of the placement frame, a support shaft slidably connected inside the placement groove, a lead screw rotatably connected inside the support shaft, a movable sleeve slidably connected outside the support shaft, and a fixed sleeve fixedly connected to the side of the support shaft away from the movable sleeve.

[0008] As a preferred embodiment of this utility model, both the movable sleeve and the fixed sleeve are rotatably connected to a mounting base on their exteriors, and a linkage rod is rotatably connected inside the mounting base. The end of the linkage rod away from the mounting base is rotatably connected to an unfolding plate.

[0009] As a preferred embodiment of this utility model, a limiting groove is formed on the outside of the support shaft, a threaded sleeve is threadedly connected to the outside of the lead screw, a retaining strip is fixedly connected to the outside of the threaded sleeve, and the retaining strip passes through the limiting groove and is fixedly connected to the movable sleeve.

[0010] As a preferred embodiment of this utility model, the placement frame is symmetrically slidably connected with sliding rods, the top of the sliding rods is fixedly connected with a stop bar, and the bottom of the sliding rods is symmetrically fixedly connected with limit rings.

[0011] As a preferred embodiment of this utility model, a telescopic cylinder is fixedly connected to the bottom of the inner side of the placement frame, and a connecting plate is fixedly connected to the output end of the telescopic cylinder. Grooves are provided at both ends of the connecting plate and between the limiting rings.

[0012] As a preferred embodiment of this utility model, the surface of the slide bar is provided with a straight groove, the bottom of the straight groove is provided with an inclined groove, and a positioning post is fixedly connected to the outside of the placement frame, the positioning post extending into the inside of the straight groove.

[0013] As a preferred embodiment of this utility model, a gear is rotatably connected to the middle of the inside of the operating table, and toothed plates are symmetrically meshed with the outside of the gear. The ends of the two sets of toothed plates that are far apart are respectively fixedly connected to the connecting table.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the threaded sleeve moves horizontally outside the lead screw, and the locking strip drives the movable sleeve to slide outside the support shaft and move closer to the fixed sleeve. Then the linkage rod unfolds and drives the unfolding plate to expand outward, thereby achieving the fitting of through holes of different sizes.

[0016] 2. In this utility model, the telescopic cylinder drives the connecting plate to slide downwards, while the groove squeezes the limiting ring, causing the slide rod to move downwards. As the positioning pin slides inside the straight groove and the inclined groove, the slide rod is turned, causing the stop bars to move closer to each other, protecting the top of the support shaft and preventing it from falling.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0024] A rotor winding frame includes a support foot 1, an operating table 2 fixedly connected to the top of the support foot 1, a connecting platform 3 slidably connected inside the operating table 2, a telescopic rod 4 fixedly connected to the top of the connecting platform 3, a flat plate 5 fixedly connected to the top of the telescopic rod 4, a placement frame 6 fixedly connected to the top of the flat plate 5, a placement groove 7 with a V-shaped structure design on the top of the placement frame 6, a support shaft 8 slidably connected inside the placement groove 7, a lead screw 9 rotatably connected inside the support shaft 8, a movable sleeve 10 slidably connected outside the support shaft 8, and a fixed sleeve 11 fixedly connected to the outside of the support shaft 8 and away from the movable sleeve 10. By contacting the support foot 1 with the ground, the rotor is then placed on the outside of the support shaft 8, and the two ends of the support shaft 8 are then placed inside the placement groove 7. The two sets of connecting platforms 3 are then brought closer together to adjust the operating range, and the telescopic rod 4 is activated to adjust the height of the flat plate 5, effectively preventing the rotor from contacting the operating table 2 and causing damage. Finally, the lead screw 9 is rotated.

[0025] Furthermore, in this embodiment, both the movable sleeve 10 and the fixed sleeve 11 are rotatably connected to the outside of the mounting base 12. The mounting base 12 is rotatably connected to the inside of the linkage rod 13. The end of the linkage rod 13 away from the mounting base 12 is rotatably connected to the unfolding plate 14. The support shaft 8 has a limiting groove 15 on its outside. The screw 9 is threadedly connected to the outside of the threaded sleeve 901. The threaded sleeve 901 is fixedly connected to the outside of the threaded sleeve 901. The locking strip passes through the limiting groove 15 and is fixedly connected to the movable sleeve 10. When the screw 9 is rotated, the threaded sleeve 901 will synchronously react with the screw 9. Then the threaded sleeve 901 will translate outside the screw 9 and be limited by the limiting groove 15. Then the locking strip will drive the movable sleeve 10 to slide outside the support shaft 8 and move closer to the fixed sleeve 11. Then the linkage rod 13 will unfold and drive the unfolding plate 14 to expand outward, thereby completing the fitting of the through-shaft holes of different sizes.

[0026] Furthermore, in this embodiment, a sliding rod 16 is symmetrically slidably connected inside the placement frame 6. A stop bar 17 is fixedly connected to the top of the sliding rod 16, and a limit ring 18 is symmetrically fixedly connected to the bottom of the sliding rod 16. A telescopic cylinder is fixedly connected to the bottom of the inner side of the placement frame 6. A connecting plate 19 is fixedly connected to the output end of the telescopic cylinder. Grooves are provided at both ends of the connecting plate 19 and between the limit rings 18. A straight groove 20 is provided on the surface of the sliding rod 16, and an inclined groove 21 is provided at the bottom of the straight groove 20. A positioning post 22 is fixedly connected to the outside of the placement frame 6. The positioning post 22 extends into the inside of the straight groove 20. By driving the telescopic cylinder, the connecting plate 19 slides downward, and at the same time, the groove squeezes the limit ring 18, so that the sliding rod 16 moves downward. As the positioning post 22 slides inside the straight groove 20 and the inclined groove 21, it turns the sliding rod 16, so that the stop bars 17 move closer to each other, protecting the top of the support shaft 8 and preventing it from falling.

[0027] Furthermore, in this embodiment, a gear 23 is rotatably connected to the middle of the inside of the operating table 2, and a toothed plate 24 is symmetrically meshed with the outside of the gear 23. The ends of the two sets of toothed plates 24 that are far apart are respectively fixedly connected to the connecting table 3. By rotating the gear 23, the toothed plate 24 will mesh with the gear 23, thereby generating a pulling force on the two sets of connecting tables 3, so as to bring them closer to each other.

[0028] In this embodiment, the specific implementation scenario is as follows: By contacting the support foot 1 with the ground, the rotor is then sleeved on the outside of the support shaft 8. By rotating the gear 23, the rear gear plate 24 meshes with the gear 23, thereby generating tension on the two sets of connecting platforms 3, bringing them closer together. Then, the two ends of the support shaft 8 are placed inside the placement groove 7, and the two sets of connecting platforms 3 are brought closer together. The operating range is adjusted, and the telescopic rod 4 is activated to achieve height adjustment of the flat plate 5, effectively preventing the rotor from contacting the operating platform 2 and causing damage. Then, the lead screw 9 is rotated, and the threaded sleeve 901 is flat on the outside of the lead screw 9. The movement is limited by the limiting groove 15, and then the locking strip drives the moving sleeve 10 to slide outside the support shaft 8 and move closer to the fixed sleeve 11. Then the linkage rod 13 unfolds and drives the unfolding plate 14 to expand outward, thereby achieving the fitting of different sized through shaft holes. By driving the telescopic cylinder, the connecting plate 19 slides downward, and at the same time the groove squeezes the limiting ring 18, so that the slide rod 16 moves downward. As the positioning post 22 slides inside the straight groove 20 and the inclined groove 21, the slide rod 16 is turned, so that the stop rods 17 move closer to each other, protecting the top of the support shaft 8 and preventing it from falling.
