One end of the dust suction pipe 203 is provided with a dust suction assembly 204;

[0048] The fan blade detection unit 300 includes a baffle 301. The lower surface of the baffle 301 is fixedly connected to the upper surface of the base 101.

The weight reducer 111 and the weight increaser 112 are respectively fixedly connected to the outer surfaces of the lifters 110 on both sides. The sliding groove 105 on the column 104, in cooperation with the lead screw 107 and the cross plate 108, forms an adjustment mechanism. The electric guide rail 109 drives the lifters 110 to lift and adjust the weight reducer 111 and the weight increaser 112, thereby changing the weight balance state of the device, enabling the device to achieve dynamic balance correction under different weight conditions. The vacuum pump 202 sucks the dust and debris generated during the processing into the storage box 201 through the dust suction pipe 203. The dust suction assembly 204 ensures accurate and efficient cleaning work, avoiding dust interference with the accuracy of dynamic balance detection. The baffle 301 and the extension plate 302 form a stable detection channel. The detection assembly 303 monitors the dynamic balance state of the fan blade in real time through sensors. The electric telescopic rod 304 adjusts the position and angle of the fan blade according to the detection data to ensure the accuracy of measurement.

[0049] Among them, a connecting plate 114 is threadedly connected to the lower part of the outer surface of the lead screw 107. The outer surface of the connecting plate 114 is slidably connected to the inner wall of the base 101. The middle part of the upper surface of the connecting plate 114 is fixedly connected with a plurality of push rods 115. The lower part of the outer surface of the lead screw 107 is connected to the connecting plate 114 by threads. When the lead screw 107 rotates, the connecting plate 114 generates a linear movement under the action of the threads, realizing the precise adjustment of the entire detection device.

The controller 113 realizes the real-time monitoring and data processing of the detection process through the electrical connection with the fan blade detection unit 300, can quickly identify the quality problems of the fan blades and provide adjustment suggestions, reducing the errors caused by human intervention.

[0051] Further, the moving assembly 116 includes a fixed frame 116a. One side of the fixed frame 116a is fixedly connected to the outer surface of the base 101. The upper part of the inner wall of the fixed frame 116a is fixedly connected with a mounting frame 116b. A hydraulic cylinder 116c is fixedly connected to the inside of the mounting frame 116b. The output end of the hydraulic cylinder 116c is fixedly connected with a universal wheel 116d. By controlling the extension and contraction of the universal wheel 116d through the hydraulic cylinder 116c, the handling of the device can be facilitated. When it is necessary to move, the universal wheel 116d is pushed out to lift the device, and when in use, the device is put down, thereby improving the flexibility of the device.

[0052] Further, the dust suction assembly 204 includes a dust suction head 204a. The outer surface of the dust suction head 204a is slidably connected to the upper part of the inner wall of the base 101. The lower end of the dust suction head 204a is fixedly connected to one end of the dust suction pipe 203.

A drawer is provided inside the storage box 201. The dust suction pipe 203 is a telescopic hose. The inside of the dust suction head 204a is slidably connected to the outer surface of the detector 102. The lower surface of the dust suction head 204a is attached to the upper surface of the push rod 115. The dust suction head 204a is connected to the storage box 201 through the dust suction pipe 203. Relying on the negative pressure generated by the dust suction pump, the dust and sundries on the upper part of the inner wall of the base 101 are sucked into the storage box 201 to complete the cleaning task. The sliding connection design of the dust suction head 204a and the linkage of the push rod 115 ensure that the dust suction head 204a can cover all corners of the device and maintain good contact with the cleaning surface, effectively avoiding cleaning blind spots and greatly improving the cleaning efficiency. The combined design of the openings 204b on the upper surface of the dust suction head 204a and the electromagnets 204c can not only suck in conventional dust but also efficiently clean metal particles and iron filings, providing strong cleaning support for diverse working environments. At the same time, the electromagnets 204c can also fix the fan, improving the stability of processing.

[0053] Further, the detection assembly 303 includes a fixed box 303a. The outer surface of the fixed box 303a is fixedly connected to the inside of the extension plate 302.

During the rotation of the fan, if the detection head 303c is pushed, it can be detected. Then, by starting the electric telescopic rod 304 to push the pressing block 305 to repair the fan blades, the detection accuracy can be improved, and at the same time, the detection efficiency can be improved.

[0054] Furthermore, a method for using an automatically leveling dynamic balance detection device for metal fan blades includes the following steps:

[0055] S1. Install the fan on the outer surface of the mounting post 103;

[0056] S2. Start the detector 102 to drive the fan to rotate and detect through the sensor;

[0057] S3. When imbalance occurs, adjust it using the weight reducer 111 and the weight increaser 112;

[0058] S4. Start the cleaning unit 200 to collect the chips cut by the weight reducer 111;

[0059] S5. Use the detection head 303c to detect the level of the fan blade;

[0060] S6. When there are different levels, use the electric telescopic rod 304 to adjust. Through the above steps, the detection of the fan can be facilitated, the detection accuracy and efficiency are improved, and the use of the device is facilitated.

[0061] During the use process, first install the fan to be detected on the outer surface of the mounting column 103. Further, start the detector 102 through the controller 113 to drive the fan to rotate, and then the detection can be carried out through the internal sensor. After detecting the unbalanced position, control the driving motor 106 and the electric guide rail 109 to operate through the controller 113, and then the positions of the weight reducer 111 and the weight increaser 112 can be adjusted. While the driving motor 106 drives the lead screw 107 to rotate to adjust the position of the cross plate 108, it also drives the connecting plate 114 to move upward, and then the push rod 115 will push the dust suction head 204a to move upward. Then use the electromagnet 204c to fix the fan, improving the stability during processing. When using the weight reducer 111 for cutting, start the vacuum pump 202 and use the opening 204b on the dust suction head 204a to collect the chips cut by the weight reducer 111, thereby keeping the processing position clean and improving the processing efficiency. The detection component 303 can detect the level of the fan blade by using the detection head 303c. If the detection head 303c is pushed during the rotation of the fan, it can be detected. Then start the electric telescopic rod 304 to push the extrusion block 305 to repair the fan blade, thereby improving the detection accuracy and the detection efficiency at the same time.
