Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator manufacturing technology, specifically to a stator slot trimming device for generator manufacturing. Background Technology
[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, which converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and then transmits it to the generator, which then converts it into electrical energy.
[0003] The generator mainly consists of a stator and a rotor. The main structure of the stator is formed by pressing multiple sheet-like annular metals into a three-dimensional ring structure. The inner edges of the multiple sheet-like metal rings are vertically connected with multiple annularly distributed grooves. These grooves form multiple wire grooves on the three-dimensional ring structure. The wire rings are then installed in these wire grooves according to certain rules to form the stator. Since the wire rings need to be inserted into the wire grooves, the wire grooves need to be trimmed beforehand to facilitate the subsequent installation of the wire rings. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a stator slot trimming device for generator production, which solves the problem that the slots need to be trimmed beforehand during stator assembly to facilitate the subsequent insertion of wire rings.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a stator slot trimming device for generator production, comprising a device platform and multiple trimming mechanisms. A gantry frame is fixedly connected to the upper surface of the device platform. Multiple electrically controlled telescopic rods are vertically fixedly connected to the bottom end of the crossbeam of the gantry frame. A horizontal plate is provided at the bottom end of the multiple electrically controlled telescopic rods. A multi-rail pulley is vertically rotatably connected to the middle of the bottom end of the horizontal plate. The multiple trimming mechanisms are all located at the bottom end of the horizontal plate.
[0006] All of the trimming mechanisms have the same structure. One of the trimming mechanisms includes a horizontal groove that runs vertically through the upper surface of the transverse disc along its radius. A slider is slidably connected inside the horizontal groove along its length. A rotating rod is vertically rotatably connected to the bottom end of the slider. A driven pulley is fixedly connected to the upper part of the outer surface of the rotating rod. A trimming cotton tube is fixedly connected to the lower part of the outer surface of the rotating rod along its length. A sliding groove is formed at the bottom end of the transverse disc, located between the horizontal groove and the multi-track pulley. A spring rod is horizontally fixedly connected to one end of the sliding groove. A movable block is slidably connected inside the sliding groove to the other end of the spring rod. A vertical rod is horizontally rotatably connected to the bottom end of the movable block. A tightening pulley is fixedly connected to the outer surface of the vertical rod. The multi-track pulley, the tightening pulley, and the driven pulley are connected by belt drive.
[0007] Furthermore, a threaded rod is vertically fixedly connected to the top of the slider, and the top of the threaded rod extends to the top of the transverse plate through the transverse groove. A threaded sleeve is threadedly connected to the outer surface of the threaded rod.
[0008] Furthermore, an anti-slip ring is fixedly connected to the bottom end of the threaded sleeve, and anti-slip texture is provided on the outer surface of the threaded sleeve.
[0009] Furthermore, a rotating motor is fixedly connected to the bottom end of each of the multiple electrically controlled telescopic rods, and a device frame is fixedly connected to the bottom end of the output shaft of the rotating motor, with the cross plate fixedly connected to the bottom end of the device frame.
[0010] Furthermore, an adjusting motor is vertically fixedly connected inside the device frame, and the output shaft of the adjusting motor rotatably passes through the transverse disc and is fixedly connected to the top of the multi-rail pulley.
[0011] Furthermore, a plurality of support pads are fixedly connected to the bottom end of the device platform.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This stator slot trimming equipment for generator production, by setting multiple trimming mechanisms, can trim the stator slots through the trimming mechanisms during use. After the multi-rail pulley in the device starts to rotate, it will drive the driven pulley connected to it to rotate. During the rotation of the driven pulley, the rotating rod fixedly connected to it will rotate synchronously. During this process, the rotating rod is inserted into the stator slot, and the trimming cotton tube that rotates synchronously on its surface can clean and trim the inside of the stator slot, ensuring that the subsequent insertion of the coil can be smoother and more efficient, thereby improving the overall work efficiency.

Detailed Implementation
[0017] 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.
[0018] Please see Figure 1-3 This utility model provides a technical solution: a stator slot trimming device for generator production, including a device platform 1 and multiple trimming mechanisms. A gantry frame 2 is fixedly connected to the upper surface of the device platform 1. Multiple electrically controlled telescopic rods 3 are vertically fixedly connected to the bottom of the crossbar of the gantry frame 2. A horizontal plate 6 is provided at the bottom of the multiple electrically controlled telescopic rods 3. A multi-rail pulley 8 is vertically rotatably connected to the middle of the bottom of the horizontal plate 6. Multiple trimming mechanisms are all located at the bottom of the horizontal plate 6.
[0019] The multiple trimming mechanisms have the same structure. One of the trimming mechanisms includes a horizontal groove 9 that runs vertically through the upper surface of the horizontal disc 6 along its radius. A slider 10 is slidably connected inside the horizontal groove 9 along its length. A rotating rod 13 is vertically rotatably connected to the bottom end of the slider 10. A driven pulley 14 is fixedly connected to the upper part of the outer surface of the rotating rod 13. A trimming cotton tube 15 is fixedly connected to the lower part of the outer surface of the rotating rod 13 along its length. A sliding groove 16 is provided at the bottom end of the horizontal disc 6, located between the horizontal groove 9 and the multi-track pulley 8. A spring rod 17 is horizontally fixedly connected to one end of the sliding groove 16. A movable block is slidably connected inside the sliding groove 16 to the other end of the spring rod 17. A vertical rod 18 is horizontally rotatably connected to the bottom end of the movable block. A tightening pulley 19 is fixedly connected to the outer surface of the vertical rod 18. The multi-track pulley 8, the tightening pulley 19, and the driven pulley 14 are connected by belt drive.
[0020] When using this device, the positions of the two rotating rods 13 are first adjusted according to the specific specifications of the stator to be processed. During adjustment, the positions of the rotating rods 13, which are rotatably connected to the two sliders 10, are driven by moving the two sliders 10. Once the positions of the two rotating rods 13 are adjusted to the appropriate positions, the device can be started. At this time, the multi-rail pulley 8 will rotate, which will drive the driven pulley 14 in the trimming mechanism connected to it to rotate. Then, the rotating rods 13 will rotate synchronously. At this time, the extension of the electrically controlled telescopic rod 3 will drive the horizontal plate 6 and its lower structure to move down synchronously, so that the part of the trimming cotton tube 15 driven by the rotating rod 13 is inserted into the wire groove of the stator. During the rotation of the rotating rod 13, the trimming cotton tube 15 can clean and trim the inside of the stator wire groove, which facilitates the subsequent installation of the coil and improves the overall work efficiency.
[0021] During the movement of slider 10, the distance between driven pulley 14 and multi-track pulley 8 changes. Therefore, it is necessary to tighten pulley 19 to maintain the tension of the transmission belt. Tightening pulley 19 is installed at the bottom of movable block via vertical rod 18. Movable block is slidably connected to the inside of slide groove 16. Therefore, movable block and tightening pulley 19 have the same mobility. At the same time, spring rod 17 is provided inside slide groove 16, which can continuously apply a pushing force to movable block. This force enables tightening pulley 19 to always apply an outward supporting force to the transmission belt, thereby ensuring that the transmission belt always remains taut and does not slip.
[0022] A threaded rod 11 is vertically fixed to the top of the slider 10. The top of the threaded rod 11 extends to the top of the transverse plate 6 through the transverse groove 9. A threaded sleeve 12 is threadedly connected to the outer surface of the threaded rod 11.
[0023] The bottom end of the threaded sleeve 12 is fixedly connected with an anti-slip ring, and the outer surface of the threaded sleeve 12 is provided with anti-slip texture.
[0024] After moving the slider 10 to the appropriate position, the threaded sleeve 12 can be rotated until the anti-slip ring at its bottom end is tightly fitted with the upper surface of the transverse plate 6. The slider 10 is fixed in position by friction, and the anti-slip texture can play an anti-slip role, making it convenient for people to rotate the threaded sleeve 12.
[0025] Multiple electrically controlled telescopic rods 3 are fixedly connected to the bottom ends of rotating motors 4, and the bottom ends of the output shafts of rotating motors 4 are fixedly connected to device frames 5. A horizontal plate 6 is fixedly connected to the bottom end of device frames 5.
[0026] When the rotating motor 4 is running, it can drive the device frame 5 and its lower structure to rotate, thereby adjusting the position of the trimming mechanism and trimming all the slots of the stator without moving the stator.
[0027] An adjusting motor 7 is vertically fixedly connected inside the device frame 5. The output shaft of the adjusting motor 7 rotatably passes through the horizontal plate 6 and is fixedly connected to the top of the multi-track pulley 8.
[0028] Once the regulating motor 7 is started, it can provide power to the multi-rail pulley 8, causing it to rotate.
[0029] Multiple support blocks 20 are fixedly connected to the bottom of the device platform 1.
[0030] The support pad 20 provides support.
[0031] When using this device, the positions of the two rotating rods 13 are first adjusted according to the specific specifications of the stator to be processed. During adjustment, the positions of the rotating rods 13, which are rotatably connected to the two sliders 10, are driven by moving the two sliders 10. Once the positions of the two rotating rods 13 are adjusted to the appropriate positions, the device can be started. At this time, the multi-rail pulley 8 will rotate, which will drive the driven pulley 14 in the trimming mechanism connected to it to rotate. Then, the rotating rods 13 will rotate synchronously. At this time, the extension of the electrically controlled telescopic rod 3 will drive the horizontal plate 6 and its lower structure to move down synchronously, so that the part of the trimming cotton tube 15 driven by the rotating rod 13 is inserted into the wire groove of the stator. During the rotation of the rotating rod 13, the trimming cotton tube 15 can clean and trim the inside of the stator wire groove, which facilitates the subsequent installation of the coil and improves the overall work efficiency.
