[0024] See also Figure 1-4The utility model provides a technical solution: a positioning device for processing a generator shaft, comprising a workbench 1, a positioning structure and a limiting structure. A fixing member 2 is fixedly connected to the top of the workbench 1, and a moving member 3 is slidably connected to the top of the workbench 1. The positioning structures are respectively located on the fixing member 2 and the moving member 3. The positioning structure comprises a fixing plate 8, a rotating plate 9, a knob 10, a clamping plate 11, a threaded rod 12 and a moving plate 13. The fixing plate 8 is fixedly connected to the surface of the moving member 3, the rotating plate 9 is rotatably connected to the fixing plate 8, the threaded rod 12 is rotatably connected to the inside of the rotating plate 9, the moving plate 13 is threadedly sleeved on the outer surface of the threaded rod 12, the clamping plate 11 is fixedly connected to the moving plate 13, and the knob 10 is The threaded rod 12 is fixedly connected, and the surface of the rotating plate 9 is provided with a groove for the sliding of the movable plate 13. The generator shaft is placed between the two clamping plates 11, and then the knob 10 is rotated to drive the threaded rod 12 to rotate, and the two movable plates 13 move toward each other and drive the two clamping plates 11 to move. The clamping plate 11 is arc-shaped and can clamp and fix the generator shaft. Since the rotating plate 9 and the fixed plate 8 are rotatably connected, the generator shaft can be clamped and fixed while rotating, which is beneficial to subsequent grinding and polishing operations. The functionality is more diverse, which solves the problem that most existing fixing methods use clamping to fix, and cannot be rotated after clamping, and the functionality is relatively limited and inconvenient to use.

[0025] Furthermore, the limiting structure is located on the moving part 3, and the limiting structure includes a ratchet 14, a gear 15, a pawl 16, a slide bar 17, a spring 18, a pull plate 19 and a side plate 20. The ratchet 14 is rotatably connected to the surface of the moving part 3, the gear 15 is fixedly connected to the ratchet 14, the pawl 16 is arranged on the surface of the moving part 3, the slide bar 17 is fixedly connected to the pawl 16, the pull plate 19 is fixedly connected to the slide bar 17, the side plate 20 is fixedly connected to the surface of the moving part 3, and the spring 18 is fixedly connected between the pawl 16 and the side plate 20. The top of the workbench 1 is fixedly connected with a support plate 7, and the top of the support plate 7 is provided with a tooth groove 21 adapted to the gear 15, and the moving part 3 moves closer to the workbench 1. The fixing part 2 can be moved in different directions to fix generator shafts of different lengths. At this time, the gear 15 rotates along the tooth groove 21 and drives the ratchet 14 to rotate clockwise. The pawl 16 does not limit the ratchet 14. After the generator shaft is fixed, the pawl 16 limits the counterclockwise rotation of the ratchet 14, so that the movable part 3 cannot move away from the fixing part 2, thereby realizing the fixation of generator shafts of different lengths. The pull plate 19 can be pulled to drive the sliding rod 17 and the pawl 16 to move so that the pawl 16 is disengaged from the ratchet 14, and then the movable part 3 can be returned to its original position. Different generator shafts can be fixed through the limiting structure, and the operation is convenient, time-saving and labor-saving, and work efficiency is improved.

[0026] Secondly, a motor 4 is fixedly connected to the surface of the fixing part 2, and the output shaft of the motor 4 is fixedly connected to the rotating plate 9. The rotation of the generator shaft can be realized by driving the rotating plate 9 to rotate by the motor 4. A bracket 5 is fixedly connected to the top of the workbench 1, and an arc plate is fixedly connected to the top of the bracket 5. The arc plate is located below the generator shaft and can support it, making it more convenient to install. A slide groove 6 is provided on the top of the workbench 1 for the moving part 3 to slide.

[0027] Working principle: place the generator shaft on the bracket 5, place the generator shaft between the two clamping plates 11, then rotate the knob 10 to drive the threaded rod 12 to rotate, the two movable plates 13 move toward each other, and drive the two clamping plates 11 to move. The clamping plates 11 are arc-shaped, which can clamp and fix the generator shaft. The rotation of the generator shaft can be achieved by driving the rotating plate to rotate by the motor 4. The movable part 3 moves toward the fixed part 2 to facilitate the fixation of generator shafts of different lengths. At this time, the gear 15 rotates along the tooth groove 21 and drives the ratchet 14 to rotate clockwise. The pawl 16 does not limit the ratchet 14. After the generator shaft is fixed, the pawl 16 limits the counterclockwise rotation of the ratchet 14, so that the movable part 3 cannot move in the direction away from the fixed part 2, so as to achieve the fixation of generator shafts of different lengths. The pull plate 19 can be pulled to drive the sliding rod 17 and the pawl 16 to move so that the pawl 16 disengages from the ratchet 14, and then the movable part 3 can be returned to its original position.

[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
