[0020] Reference Figures 1 to 3 This application provides a generator shaft outer diameter gauge, including a base 100, a clamping seat 200 mechanism, and a measuring mechanism. The clamping seat 200 mechanism includes clamping seats 200, and at least three clamping seats 200 are provided. The three clamping seats 200 correspond to the first shaft segment 410, the second shaft segment 420, and the third shaft segment 430 of the generator shaft 400, respectively. The clamping seats 200 corresponding to the first shaft segment 410 and the third shaft segment 430 are provided with clamping grooves 210, which are used to support the first shaft segment 410 and the third shaft segment 430, respectively. The shaft segment 430 and the base 100 are provided with a first positioning block 110. The end of the first shaft segment 410 or the third shaft segment 430 abuts against the first positioning block 110. The base 100 is provided with a detector 120, which is used to detect whether the cassette 200 mechanism has a generator shaft 400. The measuring mechanism includes a measuring head 300 and a pneumatic measuring instrument. The measuring head 300 is symmetrically arranged on both sides of the cassette 200. The pneumatic measuring instrument is connected to the measuring head 300 and the pneumatic measuring instrument is connected to the detector 120.

[0021] During measurement, a standard part is first placed on the mounting bracket 200 for calibration. Then, the generator shaft 400 is placed on the mounting bracket 200, with both ends of the generator shaft 400 embedded in the mounting slots 210. The end of the first shaft segment 410 or the second shaft segment 420 abuts against the first positioning block 110 for rapid positioning. After the detector 120 detects the presence of the generator shaft 400, it transmits a signal to the pneumatic measuring instrument. The pneumatic measuring instrument then inputs gas into the measuring head 300 to measure the outer diameters of the first shaft segment 410, the second shaft segment 420, and the third shaft segment 430, respectively. The measurement results are then confirmed by the pneumatic measuring instrument. The generator shaft outer diameter gauge described in this embodiment can complete the outer diameter measurement of the three shaft segments of the generator shaft 400 in one operation, eliminating the need for manual measurement, ensuring measurement accuracy, and improving measurement efficiency.

[0022] In this embodiment, four mounting brackets 200 are provided, and two mounting brackets 200 are correspondingly provided for the second shaft segment 420. Specifically, the second shaft segment 420 of the generator shaft 400 is relatively long. By measuring the outer diameter of the second shaft segment 420 through the measuring heads 300 on the two mounting brackets 200, the accuracy of the measurement can be further improved, ensuring product quality.

[0023] Furthermore, a second positioning block 130 is provided on one side of the base 100, and the card holder 200 abuts against the second positioning block 130. By providing the second positioning block 130, each card holder 200 can be quickly positioned, improving the installation efficiency of the card holder 200.

[0024] Reference Figure 2 It is conceivable that the base 100 is provided with a sliding groove 140, and a slider 150 is slidably mounted on the sliding groove 140, with the slider 150 fixedly connected to the card holder 200. At this time, the position of the card holder 200 can be adjusted, thereby realizing the position adjustment of the measuring head 300 to adapt to generator shafts 400 of different lengths, thus expanding the scope of application and reducing production costs.

[0025] It should be noted that the base 100 can also be equipped with a slide rail, and the card holder 200 is equipped with a slide block. The slide block and the slide rail cooperate to adjust the position of the card holder 200, thereby adjusting the position of the measuring head 300. The structure is simple and the operation is convenient.

[0026] It is easy to understand that the slot 210 is designed as a V-groove, which can accommodate the measurement of generator shafts 400 of different diameters, thus expanding its applicability. Of course, the slot 210 can also be equipped with two rows of rollers, which not only support the generator shaft 400 through the rollers, but also accommodate generator shafts 400 of different diameters.

[0027] Reference Figure 3In some embodiments of this application, the first positioning block 110 is provided with a connecting seat 160, which is slidably connected to the base 100. By sliding the connecting seat 160, the position of the first positioning block 110 can be adjusted to accommodate generator shafts 400 of different specifications.

[0028] Reference Figure 3 In some embodiments of this application, the detector 120 is provided with a mounting base 170, which is slidably connected to the base 100 to facilitate the installation of the detector 120. This design is simple in structure and easy to operate. The detector 120 is configured as an infrared through-beam sensor. Alternatively, the detector 120 can also be configured as a trigger switch. When the generator shaft 400 is placed in the mounting bracket 200, the trigger switch is activated, causing the pneumatic measuring instrument to operate and perform measurements. This design is simple in structure and easy to operate.

[0029] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
