The base 41 is fixedly mounted on the upper end surface of the base platform 1, and the first support frame 42 and the second support frame 43 are vertically fixed at both ends of the base 41. The head of the first support frame 42 is provided with a double-wheel angle frame 421 for supporting the core shaft 52, and the double-wheel angle frame 421 is fixedly connected to the first support frame 42. The structural setting of the integral swing frame 4 ensures that the crossflow fan blade 5 is installed through the first support frame 42 and the second support frame 43 on the base 41. Since one end of the core shaft 52 of the crossflow fan blade 5 is supported on the double-wheel angle frame 421, it is ensured that the core shaft 52 can be supported by the roller on the double-wheel angle frame 421 when in use, and it is also convenient for the core shaft 52 to stably rotate on the double-wheel tripod 421.

[0041] When operating, first calibrate, then compare the positive and negative angles, then add weights, and finally correct the machine angle. The specific steps are as follows:

[0042] 1. Calibration: Press "Dynamic balancing debugging" to enter the dynamic balancing debugging interface

[0043] Step 1: Press <Synthesis> to install the standard parts (screws to 0°, adjust the laser head and aim at the blade edge of the fan blade). Press <Start Button> to start the balancing machine. After the progress bar is completed and the <Memory> icon is displayed, press <Stop Button> to stop the machine.

[0044] Step 2: Press the 〈Left Weight〉 to add a 1 gram weight to the left spot. Press the 〈Start Button〉 to start the balancing machine. After the progress bar is completed and the 〈Memory〉 icon is displayed, press the 〈Stop Button〉 to stop the machine.

[0045] Step 3: Press the <Right Weight> button to remove the standard weight on the left and add a 1 gram weight to the right spot. Press the <Start Button> button to start the balancing machine. After the progress bar is completed and the <Memory> icon is displayed, press the <Stop Button> button to stop the machine.

[0046] Step 4: Press <Reverse> to remove the standard weight on the right. Loosen the wind blade screw, press the <Switch Button> to rotate the balancing machine spindle 180°, and tighten the screw. Press the <Start Button>

[0047] After the progress bar of starting the balancing machine is completed and the <Memory> icon is displayed, press the <Stop Button> to stop the machine.

[0048] Calibration completed.

[0049] 2. Comparison data of positive and negative angles:

[0050] Step 1: Press <Measure> and when calibrating <Reverse>, it is installed in the reverse position of 180 degrees. Press <Start Button> to start the balancing machine. When the progress bar is completed, it will stop automatically. Remember the unbalanced amount on both sides.

[0051] Step 2: Install at 180°, press the <Switch button> and rotate the main shaft of the balancing machine 180°. Loosen the fan screw, press the <Switch button> and rotate the main shaft of the balancing machine 180°. At this time, it is at position 0. Tighten the fan screw, press the <Start button> and start the balancing machine. The progress bar is completed and the machine stops automatically.

[0052] Compare with the data in step 5. If the difference is small, the calibration is correct (generally, the difference is within 0.04). If the difference is large, recalibrate from step 1. After calibration is completed, press <Return>. If the calibration is always out of tolerance, the spindle bearing may be damaged and the spindle bearing must be replaced.

[0053] 3. Add weight operation:

[0054] Step 1: Install the workpiece. Install the fan blade at the 0° position of the core shaft (if the core shaft is not at 0, press the <Reset button>), and make sure that the right light spot is shining on the blade edge of the fan blade.

[0055] Step 2: Press the Start button to start the balancing machine, and the machine will automatically measure. It will automatically stop after the measurement is completed.

[0056] Step 3: After the measurement is completed, the fan will automatically stop at the weight adding position. First add the weight on the left side, at the left spot position. The left side will be displayed in purple on the display. After adding the weight on the left side, press the <Switch button> to automatically rotate the fan blade and stop at the right weight adding position. Add weight at the right light indication position.

[0057] Far: refers to the farthest leaf away from people, close to the direction of the LCD screen, with red light shining on it.

[0058] Step 4: Press the Start button to retest. If the test is qualified, it will automatically stop at the glue adding position on the left. If it is unqualified, add weight again.

[0059] Note: Press the stop button to stop the measurement and reset (the fan blades turn to the installation position).

[0060] 4. Correct the machine angle:

[0061] If you need to change the angle of the fan blade when installing it, follow the steps below to modify it.

[0062] Step 1: Click the "Release Motor" button on the "Main Interface" and manually turn the spindle to the installation position.

[0063] Step 2: Click <Settings> on the <Main Interface> and select <Servo Settings> to enter the servo interface.

[0064] Step 3: Click the number box behind "Correct Machine Angle". A dialog box will appear. Enter 123 for the management password, enter 0.0 for the correction machine angle, and press the "OK" button. The mounting position is now set to 0°.
