Description

Technical Field

[0001] This application relates to the field of servo torsion devices, and more specifically, to a device for torsion the angle of an impeller cross. Background Technology

[0002] With social progress and the development of manufacturing, the manufacturing level of the wind turbine industry is also gradually improving, and many traditionally handmade parts are being replaced by equipment.

[0003] As a crucial component connecting the blades and motor in an axial flow fan, the torsion angle of the crossbeam is particularly important. Previously, the crossbeam was manually torn by workers, with the height difference between the two ends after torsion determining whether it was properly torn. This method is not only inaccurate, but also cannot guarantee that the torsion angle and position are consistent each time, significantly affecting the dynamic balance of the crossbeam. This is especially problematic during high-speed impeller rotation, potentially causing safety hazards.

[0004] A device for twisting the angle of the impeller cross has now been provided. Utility Model Content

[0068] The control system includes: push-button switch 32 and controller 31;

[0069] The push button switch 32 is mounted on the mounting frame 11, and the controller 31 is mounted on the mounting frame 11. The push button switch 32 is electrically connected to the controller 31, the controller 31 is electrically connected to the rotary motor 12 and the clamping cylinder 26 respectively, and the controller 31 is electrically connected to the drive motor 19.

[0070] Work or installation process:

[0071] First, install the cross impeller on the shaft end disc 18 and fix the cross impeller to the shaft end disc 18. Then, adjust the height of the cross impeller according to its height on the shaft end disc 18 so that the blades of the cross impeller are at the same height as the arc surface on the lower clamping block 34. Then, attach multiple adjusting rings 35 to the shaft end disc 18 to continuously adjust the height of the shaft end disc 18 so that the blades of the cross impeller are at the same height as the arc surface on the lower clamping block 34.

[0072] The second step is to press the button switch 32 and power on the controller 31. The controller 31 controls the drive motor 19 to start. The output shaft of the drive motor 19 drives the lead screw 20 to rotate. The lead screw 20 is threadedly connected to the slider 21 and drives the slider 21 to slide along the extension of the slide rail 22. The slider 21 drives the base 23 to move horizontally in sync. The base 23 drives the upper clamping plate 29 and the lower clamping plate 30 to move closer to the impeller until one end of the cross impeller blade moves between the upper clamping plate 29 and the lower clamping plate 30.

[0073] In the third step, at this time, one end of the cross impeller is located between the upper clamping block 33 and the lower clamping block 34. Then, the controller 31 controls the clamping cylinder 26 to start. The piston rod of the clamping cylinder 26 extends and drives the upper clamping plate 29 to move downward. The upper clamping plate 29 drives the upper clamping block 33 to move downward and make the upper clamping block 33 contact one end of the cross impeller. At this time, the upper clamping block 33 and the lower clamping block 34 clamp and fix one end of the cross impeller.

[0074] Fourth step, the torsion motor 24 starts, the output shaft of the torsion motor 24 drives the second coupling 25 to rotate, the second coupling 25 drives the mounting block 27 to rotate, the mounting block 27 drives the upper clamping plate 29 and the lower clamping plate 30 to rotate, the upper clamping plate 29 drives the upper clamping block 33 to rotate, and the lower clamping plate 30 drives the lower clamping block 34 to rotate. During the rotation of the upper clamping block 33 and the lower clamping block 34, one end of the cross blade is clamped and driven to rotate, so that one end of the cross blade performs torsion work.

[0075] The fifth step involves controlling the torsion angle of the upper clamping block 33 and the lower clamping block 34 each time via the controller 31. After one end of the cross blade completes the torsion angle operation, the clamping cylinder 26 starts in reverse and drives the upper clamping plate 29 and the upper clamping block 33 to move upward synchronously. The upper clamping block 33 releases one end of the cross blade, and the drive motor 19 starts in reverse. The drive motor 19 drives the lead screw 20 to rotate in reverse and drives the upper clamping plate 29 and the lower clamping plate 30 to move away from the end of the cross blade, so that one end of the cross blade moves out from between the upper clamping plate 29 and the lower clamping plate 30.

[0076] Step 6: Then the rotary motor 12 starts, the output shaft of the rotary motor 12 drives the first coupling 13 to rotate, the first coupling 13 drives the rotating shaft 17 to rotate, the rotating shaft 17 drives the shaft end disc 18 to rotate, the shaft end disc 18 drives the cross blade to rotate, and makes the cross blade rotate 90°.

[0077] Step 7: Repeat steps 2 to 6 above until all four ends of the cross blade have completed the twisting operation and each blade has the same twist angle.

[0078] Finally, remove the cross blades that have completed the twisting operation from the shaft end disk 18, and repeat the first to seventh steps above to perform the twisting operation on the remaining cross blades.
