Specifically, the driving cylinder is a cylinder.

[0033] In order to further understand the present invention, this embodiment also discloses a detection method of the electromagnetic fan amplitude detection system, and the technical solution adopted is as follows:

[0034] A detection method of the electromagnetic fan amplitude detection system comprises the following steps:

[0035] S1: Start electromagnetic fan 1;

[0036] S2: Aim the laser distance measuring device 2 at the blade 11 of the electromagnetic fan 1, and keep an effective distance between the laser distance measuring device 2 and the electromagnetic fan 1; when the laser distance measuring device 2 is used to measure the distance of the blade 11 of a single electromagnetic fan 1, fix the electromagnetic fan 1 on the fixing seat 6, and then align the laser emitted by the laser distance measuring device 2 on the workbench 5 with the surface of the blade 11 to be measured.

[0037] S3: A row of lasers is emitted to the blade 11 through the laser ranging device 2 within a preset time. After the laser is blocked by the blade 11, the laser ranging device 2 receives the blocking information of the blade 11, and sends the blocking information to the processing control unit. The processing control unit obtains the amplitude of the electromagnetic fan 1 through data processing, and the processing control unit sends the amplitude information to the display unit, which displays the amplitude information through the display unit.

[0038] In this embodiment, the preset time is the time of at least one vibration cycle of the blade 11. Preferably, the preset time is 0.5S. When the laser distance measuring device 2 is controlled by a computer, the preset time can be set by the computer. The effective distance is at least 1m. Preferably, the effective distance is 1m.

[0039] In this embodiment, in step S3, the processing control unit obtains the distance maxD by processing the blocking information, and the distance maxD is the distance between the blade 11 and the laser distance measuring device 2 when the blade 11 is farthest from the equilibrium position;

[0040] The processing control unit then performs the following calculation to obtain the amplitude F: D is the distance between the blade 11 and the laser distance measuring device 2 when the blade 11 is in a balanced position. D can be measured by the laser distance measuring device 2 during commissioning and stored in the processing control unit as known data.

[0041] In this embodiment, in step S1, a plurality of electromagnetic fans 1 are sequentially fixed at the fixed stations 61;

[0042] In step S2, the laser distance measuring device 2 is aligned with one of the two blades 11 of each electromagnetic fan 1;

[0043] In step S3 , the lateral moving device 3 drives the laser distance measuring device 2 to move, and the laser distance measuring device 2 measures the amplitude F of the blade 11 during the movement.

[0044] In this embodiment, in step S3, after the laser distance measuring device 2 measures the amplitude F of one blade 11 of each electromagnetic fan 1, the longitudinal moving device 4 drives the laser distance measuring device 2 to move, so that the laser distance measuring device 2 is aligned with another blade 11 of each electromagnetic fan 1, and then the transverse moving device 3 drives the laser distance measuring device 2 to move back, and the laser distance measuring device 2 measures the amplitude F of another blade 11 of each electromagnetic fan 1 during the movement. When measuring the first amplitude of the electromagnetic fan 1, if the laser distance measuring device 2 is aligned with the blade 11 close to the transverse moving device 3. When measuring the amplitude of another blade 11 of each electromagnetic fan 1, before the transverse moving device 3 moves back, the longitudinal moving device 4 extends forward, so that the laser distance measuring device 2 is aligned with the blade 11 away from the transverse moving device 3. The transverse moving device 3 can measure the amplitude of another blade 11 of each electromagnetic fan 1 during the movement. Conversely, the longitudinal moving device 4 is extended and retracted, so that the laser distance measuring device 2 is aligned with the blade 11 away from the transverse moving device 3. The lateral moving device 3 can measure the amplitude of the blade 11 during the movement.

[0045] Please refer to Figure 4 , Figure 4 Function A indicates that the laser distance measuring device 2 sends distance data to the computer, and the computer can also send a control signal to the laser distance measuring device 2; Function B indicates that the lateral moving device 3 can drive the laser distance measuring device 2 to move; Function C indicates that the computer can control the moving speed of the lateral moving device 3.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
