Description

Technical Field

[0001] This utility model relates to the field of straightening device technology, specifically a straightening device for stator production. Background Technology

[0002] During the operation of a wind turbine, the stator is subjected to various forces, such as electromagnetic forces and mechanical vibrations. After straightening, the copper bar coils used in the stator can be better fixed in the stator slots, enhancing the overall mechanical strength of the stator windings and enabling them to withstand these forces without displacement, deformation, or damage. This is crucial for preventing winding short circuits, grounding, and other faults caused by loose or displaced copper bars, and can effectively improve the reliability and stability of the generator in harsh operating environments.

[0003] The existing patent publication number CN222659948U discloses a straightening mechanism for flat copper wires of motor stators, relating to the technical field of straightening mechanisms. This utility model includes a body with several cylindrical blocks rotatably arranged on its outer surface. An adjustment device is also provided on the outer surface of the body, including a screw. The bottom end of the screw is rotatably connected to one side of the top of the body. By setting the adjustment device, when using the straightening mechanism to straighten flat copper wires, the screw can be rotated to drive a rectangular plate to slide on one side of the body, adjusting the distance between the positioning block and the cylindrical block. This facilitates the straightening of flat copper wires of different thicknesses through the cylindrical block and the positioning block, improving the flexibility and practicality of the straightening mechanism. However, during use, this straightening device collects the straightened flat copper wires using a collection device. Because the collection box is relatively simple, when the flat copper wires are collected inside, the falling flat copper wires collide with the flat copper wires inside the collection box, causing damage to the surface of the flat copper wires. Therefore, we propose a straightening device for stator production to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a straightening device for stator production, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A straightening device for stator production includes a support frame, a support plate fixed to the top of the support frame, a straightening mechanism body mounted on the top of the support plate, a receiving seat fixed to the top of the support plate on one side of the straightening mechanism body, a rotating shaft rotatably connected to both sides of the receiving seat via bearings, a horizontal plate fixed to one end of each rotating shaft, a receiving roller rotatably connected between two horizontal plates at equal intervals via bearings, a limiting plate adapted to the receiving roller fixed to one side wall of each horizontal plate, an upper limit assembly disposed between the two horizontal plates, an mounting plate fixed to the support frame, a collecting assembly sliding inside a groove opened at the top of the mounting plate, and two drive rollers for driving the collecting assembly to move rotatably connected between the mounting plate and the support plate via bearings.

[0009] Furthermore, the upper limit assembly includes a mounting base fixed to the top of two horizontal plates, a cylinder fixed to the top of the mounting base, the cylinder's ejector end slidingly extending through the mounting base to its lower part and fixed to a connecting plate, and two T-blocks fixed to the bottom of the connecting plate.

[0010] Furthermore, two guide rods slide through the top of the mounting base, and the bottom ends of the guide rods are fixedly connected to the top of the connecting plate.

[0011] Furthermore, the collection assembly includes a movable frame that slides inside a groove on the top of the mounting plate. Two side baffles are fixed on the movable frame, and material boxes that are equidistantly fixed inside the movable frame are arranged between the two side baffles. Each material box has a protective sleeve fixed inside.

[0012] Furthermore, the movable frame (1101) is rotatably connected to a roller (1105) via a bearing.

[0013] Furthermore, annular grooves are provided on both inner walls of the receiving seat, and rotating rings that are adapted to the annular grooves are fixed on one side wall of each of the two horizontal plates.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a straightening device for stator production, which has the following advantages:

[0016] This invention features a receiving seat that can receive straightened stator copper strips. When the receiving roller that receives the stator copper strips rotates and tilts, the stator copper strips can slide directly into the collection assembly. Furthermore, the material boxes in the collection assembly are all independently set, thus separating and placing the stator copper strips separately. This avoids damage to the stator copper strips when they fall and are collected, and also prevents damage when the collected stator copper strips are moved close to the ground.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of the present invention provides a straightening device for stator production, including a bracket 1, a bearing plate 2 fixed to the top of the bracket 1, a straightening mechanism body 3 mounted on the top of the bearing plate 2, a receiving seat 4 fixed to the top of the bearing plate 2 on one side of the straightening mechanism body 3, and a rotating shaft 5 rotatably connected to both side walls of the receiving seat 4 via bearings. A horizontal plate 6 is fixed to one end of each rotating shaft 5. Annular grooves 13 are formed on both inner walls of the receiving seat 4, and one side wall of each horizontal plate 6 is fixed with a groove 13. A rotating ring 14, adapted to the groove 13, provides auxiliary support for the horizontal plate 6, making it more stable during rotation. A receiving roller 7 is equidistantly connected between the two horizontal plates 6 via bearings. A limiting plate 8, adapted to the receiving roller 7, is fixed to one side wall of each horizontal plate 6. An upper limit assembly 9 is provided between the two horizontal plates 6. A mounting plate 10 is fixed to the bracket 1. A collecting assembly 11 slides inside a groove on the top of the mounting plate 10. The mounting plate 10 and the bearing plate 2 rotate via bearings. Two drive rollers 12 are connected to drive the collection assembly 11 to move. During the straightening process of using this stator production, the stator copper strip to be straightened is placed on the straightening mechanism 3 for straightening. Then, the straightened stator copper strip is conveyed to the receiving roller 7. Next, the upper limit component 9 is activated to limit the stator copper strip. Then, the motor is started to drive the rotating shaft 5 to rotate. After the rotating shaft 5 rotates, it will drive the horizontal plate 6 to rotate. After the two horizontal plates 6 rotate, they can cause the stator copper strip on the receiving roller 7 to tilt. When the stator copper strip tilts to an angle that matches the collection assembly 11, the upper limit component 9 is activated to release the restriction on the stator copper strip. Then, the stator copper strip will slide down into the inside of the collection assembly 11 for collection. When collecting the next stator copper strip, the receiving roller 7 can be rotated to reset. Then, the drive roller 12 can be activated to drive the collection assembly 11 to move forward a certain distance. At this time, the position of the collection chamber of the collection assembly 11 can be changed. Therefore, the stator copper strips that fall and are collected can be separated and collected.

[0026] like Figure 2 and Figure 3 As shown, in some embodiments, the upper limit assembly 9 includes a mounting base 901 fixed to the top of two horizontal plates 6. A cylinder 902 is fixed to the top of the mounting base 901. The top end of the cylinder 902 slides through the mounting base 901 and extends below it, where a connecting plate 903 is fixed. Two guide rods 905 slide through the top of the mounting base 901. The bottom ends of the guide rods 905 are fixedly connected to the top of the connecting plate 903, which can provide auxiliary support for the connecting plate 903 to make it more stable during up and down movement. Two T-blocks 904 are fixed to the bottom of the connecting plate 903. In use, starting the cylinder 902 can drive the connecting plate 903 to move down. After the connecting plate 903 moves down, it will drive the two T-blocks 904 to move down. After the T-blocks 904 move down, they can limit the stator copper strip on the docking roller 7.

[0027] like Figure 1 and Figure 5 As shown, in some embodiments, the collecting component 11 includes a movable frame 1101 that slides inside a groove on the top of the mounting plate 10. Rollers 1105 are rotatably connected to the movable frame 1101 via bearings. After the movable frame 1101 has finished collecting, the rollers 1105 facilitate the worker to tilt and pull the movable frame 1101. Two side baffles 1102 are fixed on the movable frame 1101, and equidistant material boxes 1103 are fixed inside the movable frame 1101 between the two side baffles 1102. Protective sleeves 1104 are fixed inside each of the material boxes 1103. When the frame is straightened... When the copper strip slides into the material box 1103, the protective sleeve 1104 can protect the copper strip and prevent its surface from being scratched. In use, when the drive roller 12 rotates, it can drive the two side baffles 1102 to move, which in turn can drive the moving frame 1101 to move. After the moving frame 1101 moves, it will drive the material box 1103 inside to move. Therefore, when collecting the stator copper strip that slides down, it can be separated and placed. In addition, a baffle is fixed on the right side inside the slide groove of the mounting plate 10, which facilitates the positioning of the moving frame 1101 that is placed inside the slide groove of the mounting plate 10 for the first time.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
