[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] Furthermore, the number of the irregularly shaped fixing blocks is four, arranged in pairs and symmetrical to each other along the vertical central axis of the calibration ring. The number of the calibration plates is also four, arranged in pairs and symmetrical to each other along the vertical central axis of the calibration ring. This design is beneficial for better calibration of shaft forgings.

[0010] Furthermore, a cleaning device is provided on the outer surface of the threaded sleeve.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5This utility model is a calibration fixture for machining shaft forgings of a speed reduction device. It includes a circular support rod 1, a machining table 2 fixedly connected to the top of the circular support rod 1, a support block 3 fixedly connected to the top of the machining table 2, a calibration ring 4 fixedly connected to the top of the support block 3, and a calibration device 5 provided on the outer surface of the calibration ring 4. The calibration device 5 includes a shaped fixing block 51 fixedly connected to the outer surface of the calibration ring 4, a three-phase asynchronous motor 52 fixedly connected to the outer surface of the shaped fixing block 51, a threaded rod 53 fixedly connected to the output shaft of the three-phase asynchronous motor 52, and a threaded sleeve 54 threadedly fitted onto the outer surface of the threaded rod 53. The above design is beneficial for the three-phase asynchronous motor 52 to drive the threaded rod 53 to work, and the threaded rod 53 to drive the threaded sleeve 54 to work.

[0027] The fixed end of the limiting telescopic rod 55 is fixedly connected to the outer surface of the threaded sleeve 54. The end of the limiting telescopic rod 55 away from the threaded sleeve 54 is fixedly connected to the outer surface of the irregular fixed block 51. The above design is beneficial for the limiting telescopic rod 55 to limit the threaded sleeve 54.

[0028] A connecting post 56 is fixedly connected to the outer surface of the threaded sleeve 54, a push plate 57 is fixedly connected to the outer surface of the connecting post 56, a push rod 58 is fixedly connected to the outer surface of the push plate 57, and a calibration plate 59 is fixedly connected to the outer surface of the push rod 58. The above design is beneficial for the threaded sleeve 54 to drive the connecting post 56 to work, and for the connecting post 56 to drive the push plate 57 to work.

[0029] There are four irregularly shaped fixing blocks 51, arranged in pairs and symmetrical to each other along the vertical central axis of the calibration ring 4. There are also four calibration plates 59, arranged in pairs and symmetrical to each other along the vertical central axis of the calibration ring 4. This design is beneficial for better calibration of shaft forgings.

[0030] A cleaning device 6 is provided on the outer surface of the threaded sleeve 54. The cleaning device 6 includes a horizontal connecting rod 61, which is fixedly connected to the outer surface of the threaded sleeve 54. The above design is beneficial for the threaded sleeve 54 to support the horizontal connecting rod 61 during operation.

[0031] A telescopic brush plate 62 is rotatably connected to the outer surface of the horizontal connecting rod 61. A circular plate 63 is fixedly connected to the top of the processing table 2. A roller 64 is rotatably connected to the top of the circular plate 63. The above design is beneficial for the processing table 2 to support the circular plate 63, and the circular plate 63 to support the roller 64 for operation.

[0032] One end of a rope 65 is fixedly connected to the outer surface of the roller 64, and the end of the rope 65 away from the roller 64 is fixedly connected to the outer surface of the telescopic brush plate 62. The above design is conducive to the rope 65 driving the telescopic brush plate 62 to rotate.

[0033] A specific application of this embodiment is as follows: The operator first moves the device to the location where the parts need to be calibrated. Then, the operator places the forged shaft of the reduction gear into the calibration ring 4. At this time, the three-phase asynchronous motor 52 on the irregularly shaped fixing block 51 starts. The start of the three-phase asynchronous motor 52 drives the threaded rod 53 to rotate. The rotation of the threaded rod 53 drives the threaded sleeve 54 to move. The movement of the threaded sleeve 54 is limited by the limiting telescopic rod 55 to prevent the threaded sleeve 54 from being rotated by the threaded rod 53. The threaded sleeve 54 can only move. The movement of the threaded sleeve 54 drives the connecting column 56 to move. The movement of the connecting column 56 drives the push plate 57 to move. The movement of the push plate 57 drives the push rod 58 to move. The movement of the push rod 58 moves the calibration plate 59, which calibrates the forged shaft of the speed reduction equipment. This allows for rapid calibration of the forged shaft and avoids errors. After calibration, the operator processes the part, and the processed debris falls onto the processing table 2. At this time, the threaded sleeve 54 moves the horizontal connecting rod 61, which in turn moves the telescopic brush plate 62. When the telescopic brush plate 62 moves to a certain extent, it is rotated by the rope 65. The telescopic brush plate 62 cleans the processing table 2, allowing it to be cleaned after processing to prevent excessive debris accumulation.
