[0024] Example 1

[0025] like Figures 1-3 As shown, a toothed impeller flatness measuring device includes a testing platform 1; a testing component 2 is installed on the testing platform 1; the testing component 2 includes a data acquisition system, a control system, display and analysis software, etc.; a placement platform 3 is set on the top surface of the testing platform 1; an auxiliary testing device is installed on the testing platform 1; the auxiliary testing device includes a fixing frame 401; fixing frames 401 are bolted to both sides of the top of the testing platform 1 on the placement platform 3; a moving plate 403 is set between the two fixing frames 401; a scraper 404 is fixedly connected to the bottom end face of the moving plate 403. After a single measurement operation is completed, the moving plate 403 drives the scraper 404 to move along the top surface of the placement platform 3, thereby achieving the effect of scraping off metal particles and debris from the top of the placement platform 3.

[0026] Two fixed frames 401 are symmetrically fixed with sliding rods 402 between their frames; a movable plate 403 is fitted onto the outside of the cross-section of the two sliding rods 402 through sliding holes; telescopic cylinders 405 are symmetrically installed on one side of one of the two fixed frames 401; the telescopic ends of the two telescopic cylinders 405 pass through the frame plate of the fixed frame 401 and are connected to the movable plate 403. When the telescopic cylinders 405 are activated, the movable plate 403 moves along the direction of the sliding rods 402, providing power for the movement of the movable plate 403 when it is in position.

[0027] Both fixed frames 401 are equipped with connecting frames 406; the connecting frames 406 are equipped with suction pipes 407; suction nozzles 408 are fixedly connected to the suction pipes 407; the working position of the suction nozzles 408 faces the placement table 3, and the working end of the suction nozzles 408 generates suction to collect metal particles on the scraper 404, ensuring the cleanliness of the scraper 404 and ensuring its subsequent continuous operation.

[0028] A collection box 409 is provided on one side of the placement platform 3; a connecting pipe 411 is installed on the top of the collection box 409; an air pump 410 is installed on the connecting pipe 411; and the end of the connecting pipe 411 is connected to two air extraction pipes 407.

[0029] Each fixed frame 401 has a fixed frame 412 welded to both sides of its frame body; a rolling brush 413 is installed between the fixed frames 412 via a rotating shaft; a small motor 414 is installed on the frame of the fixed frame 412; the output shaft of the small motor 414 is connected to the end of the rotating shaft. Some metal particles on the scraper 404 will adhere to the scraper body. In order to ensure the continuous operation of the scraper 404, the small motor 414 will drive the rolling brush 413 to rotate so as to sweep off the metal particles adhering to the scraper 404.

[0030] The horizontal plane containing the bottom end face of scraper 404 is tangent to the top end face of placement platform 3.

[0031] Through the structural design of the auxiliary detection device, after the flatness measuring device completes one operation, the telescopic cylinder 405 operates and pushes the moving plate 403 to move along the slide bar 402, so that the scraper 404 moves along the top of the placement platform 3, thereby scraping off the metal particles and debris on the top of the placement platform 3. As the moving plate 403 moves, the small motor 414 on the fixed frame 412 operates, and the rolling brush 413 rotates. When the scraper 404 approaches, the rolling brush 413 sweeps off the metal particles on the scraper 404. At the same time, the suction pump 410 on the connecting pipe 411 operates, and the working port of the suction nozzle 408 generates suction. Some metal particles will enter the interior of the collection box 409 through the suction pipe 407, ensuring the cleanliness of the platform and preventing the toothed impeller from tilting during subsequent testing, thus ensuring the accuracy of subsequent flatness measurement operations.

[0032] Example 2

[0033] like Figure 4 As shown, a moisture-proof component is installed on the movable plate 403; the moisture-proof component includes a mounting bracket 501; the mounting bracket 501 is fixed to both sides of the movable plate 403 by bolts, which can fix the working position of the air blowing pipe 502 and the air blowing nozzle 503; air blowing pipes 502 are provided between the mounting brackets 501 on the same side; the bottom of the two air blowing pipes 502 is fixed to the air blowing nozzle 503; a fan 504 is placed on the top of the movable plate 403; a heating box 505 is installed at one end of the fan 504 through a connecting pipe, and the interior of the heating box 505 is equipped with a filter screen to filter and heat the incoming air and prevent dust from falling onto the placement platform 3; one side of the heating box 505 is connected to the air blowing pipe 502 through a connecting pipe.

[0034] Through the structural design of the moisture-proof components, during the movement of the movable plate 403, the fan 504 is started, and the air drawn in enters the heating box 505. After being filtered and heated, it enters the air blowing pipe 502 and then blows onto the surface of the placement table 3 through the air blowing nozzle 503, ensuring that the surface of the placement table 3 is dry and avoiding the phenomenon that metal shavings will adhere due to excessive moisture and are difficult to scrape off.
