Description

Technical Field

[0002] The generator rotor shaft is a key component in the generator. It carries the important tasks of transmitting torque, supporting the rotor and maintaining stable operation of the generator. During the operation of the generator, the rotor shaft needs to withstand high-speed rotation and complex mechanical environment, so there are high requirements for its material and processing accuracy. The fixture can ensure the stability of the rotor shaft during the milling process. Since the milling operation involves high-speed rotating tools and workpieces, if there is no stable fixture, the rotor shaft may move or vibrate, resulting in reduced processing accuracy or damage to the workpiece.

[0003] After searching, the announcement number: CN205465292U discloses a fixture for milling grooves of automobile generator rotor shafts. The fixture used for milling grooves of automobile generator rotor shafts has two grooves arranged side by side on a base that can be fixed on a machine tool, which can be used to place the automobile generator rotor shaft. A pressure block is installed above the two grooves, and the pressure block is provided with an adjustment handle. There is a positioning block on each side of the two grooves to support the automobile axle for convenient milling groove processing of the end head. When in use, after the two rotor shafts are fixed, the end heads can be milled at the same time by two milling cutters that are aligned in an alternating manner, so that the milling groove width and depth can be consistent, which is beneficial to stabilize the processing quality and improve production efficiency. Since the fixture cannot be disassembled in this application, it may be more difficult to perform maintenance and cleaning.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a generator rotor shaft milling groove processing fixing device, including a wall panel 1, a hollow column 2 is fixedly connected to the side wall of the wall panel 1, a handle 3 is slidably connected inside the hollow column 2, a slide column 4 is fixedly connected to the side wall of the handle 3, the slide column 4 is rotatably connected to the inside of the hollow column 2, a slider 5 is slidably connected inside the slide column 4, an irregular plate 6 is fixedly connected to the side wall of the slider 5, a sliding column 7 is fixedly connected to the side wall of the irregular plate 6, a cavity 8 is opened inside the hollow column 2, the sliding column 7 is slidably connected inside the cavity 8, there are six irregular plates 6, the irregular plates 6 fit each other, a hexagonal block 9 is slidably connected inside the hollow column 2, the irregular plate 6 fits the hexagonal block 9, and an auxiliary component is arranged inside the wall panel 1;

[0023] Specifically, the handle 3 is installed on the outside of the hollow column 2, and the user can drive the internal slide column 4 to rotate by turning it. The rotation of the slide column 4 is not the purpose, but the means. Its rotational motion is converted into the sliding of the slider 5 in the internal slide rail through precise machinery. This sliding motion is a linear motion, which forms a sharp contrast with the rotational motion of the slide column 4. This conversion not only cleverly utilizes the mechanical principle, but also makes the operation of the entire device more flexible and convenient. The sliding motion of the slider 5 further drives the movement of the irregular plate 6. The irregular plate 6 is so named because its shape is irregular. This design helps to achieve more complex Mechanical movement, the movement of the irregular plate 6, through a series of sophisticated connection mechanisms, ultimately drives the sliding column 7 to slide inside the cavity 8. This sliding movement enables the sliding column 7 to flexibly enter and exit the cavity 8, thereby realizing the unlocking and movement of the fixture. When the irregular plate 6 moves to a position where it no longer fixes the hexagonal block 9, the fixture can be pulled for maintenance and repair. The hexagonal block 9 is a fixture used to keep the fixture stable while the equipment is running, but when maintenance and repair are required, it must be unlocked to be able to move and access the interior of the fixture. Through the above series of mechanical movements, users can easily achieve this goal.

[0024] Reference Figure 1 - Figure 3The auxiliary component includes a servo motor 10, which is fixedly connected to the side wall of the hexagonal block 9, and the servo motor 10 is slidably connected to the inside of the wall plate 1. The output end of the servo motor 10 is fixedly connected to a worm 11, and one end of the servo motor 10 is fixedly connected to a support plate 12, and the support plate 12 is internally rotatably connected to a worm gear 13, and the worm gear 13 is meshed with the worm 11, and the support plate 12 is internally rotatably connected to a worm gear 2 14, and the worm gear 2 14 is meshed with the worm 11. The side wall of the wall plate 1 is fixedly connected to a support block 20, and the side wall of the worm gear 13 is fixedly connected to a rotating plate 15, and the support plate 12 is internally rotatably connected to a rotating plate 2 16, and the side wall of the rotating plate 15 is rotatably connected to a rotating block 17, and the rotating plate 2 16 is rotatably connected to the inside of the rotating block 17, and the side wall of the rotating block 17 is fixedly connected to a clamping block 18, and the clamping block 18 is internally fixedly connected to an anti-slip pattern 19;

[0025] Specifically, the output end of the servo motor 10 drives the worm 11 to rotate. The rotation of the worm 11 is not isolated, but forms a precise transmission system with the worm gear 13 and the worm gear 2 14. The rotation of the worm 11 drives the worm gear 13 and the worm gear 2 14 to rotate accordingly.

[0026] As the worm gear 13 rotates, the rotating plate 15 connected thereto also starts to rotate. The rotation of the rotating plate 15 is not isolated, but is closely connected with the rotating block 17. Therefore, the rotation of the rotating plate 15 will drive the rotating block 17 to rotate accordingly, and the rotation of the rotating block 17 will further drive the rotation of the rotating plate 2 16. This series of actions are transmitted, and finally the precise control of the clamping block 18 is realized. Driven by the rotating block 17, the clamping block 18 rotates toward the center, thereby clamping the rotor shaft. The clamping accuracy and stability benefit from the precise control of the servo motor 10 and the precise coordination of the transmission mechanism. However, in order to ensure the stability and safety of the rotor shaft, the clamping operation does not stop there. After the initial clamping is completed, the staff will start the servo motor 10 on the lower side to clamp the rotor shaft again. This step ensures the stability and safety of the rotor shaft during the processing and effectively avoids accidents caused by loose clamping.

[0027] Reference Figure 1 and Figure 3 An air compressor 21 is provided on the upper surface of the support block 20, a semicircular arc 22 is fixedly connected to the upper surface of the support block 20, an air bag 23 is fixedly connected inside the semicircular arc 22, and the air compressor 21 is connected to the air bag 23;

[0028] Specifically, the function of the air compressor 21 is to provide compressed air for the airbag 23, so that it can expand or contract. A semicircular arc 22 is fixedly connected to the upper surface of the support block 20, which provides a stable support and accommodation space for the airbag 23. The inside of the semicircular arc 22 is fixedly connected to the airbag 23. The airbag 23 is made of highly elastic material and can withstand large pressure changes. When the air compressor 21 is working, it will send compressed air into the airbag 23 to make it expand rapidly; when the air compressor 21 stops working, the airbag 23 will gradually shrink under the action of its own elasticity and external pressure. It is worth mentioning that the connection pipeline between the air compressor 21 and the airbag 23 is reasonably laid out, which not only ensures the smooth flow of air, but also avoids unnecessary pressure loss.

[0029] Working principle: When the staff needs to clamp the rotor shafts of different sizes, first put the rotor shaft into the fixing device. When the bottom of the rotor shaft contacts the airbag 23, the worm 11 can be driven to rotate through the output end of the servo motor 10. The rotation of the worm 11 will drive the worm wheel 13 and the worm wheel 2 14 meshing with it to rotate. The rotation of the worm wheel 13 will drive the rotating plate 15 to rotate. The rotation of the rotating plate 15 will drive the rotating block 17 to rotate. The rotation of the rotating block 17 will drive the rotating plate 2 16 to rotate. The rotation of the rotating block 17 will drive the clamping block 18 to rotate toward the center to clamp the rotor shaft. When the servo motor on the lower side is started, 10 drives the clamping block 18 to clamp the rotor shaft again, and finally the air bag 23 is started by the air compressor 21 to expand it. At this time, the clamping of the rotor shaft is completed. When the fixing device needs to be maintained and repaired, first, the handle 3 is rotated inside the hollow column 2, which will drive the slide column 4 to rotate. The rotation of the slide column 4 will drive the slider 5 to slide in its internal slide rail. The sliding of the slider 5 will drive the irregular plate 6 to slide. The sliding of the irregular plate 6 will drive the sliding column 7 to slide inside the cavity 8. At this time, the irregular plate 6 no longer fixes the position of the hexagonal block 9, and then the fixing device can be pulled for maintenance and repair.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
