The use principle is as follows:

when the control block 21 is used, the impeller hub 16 is fixed on the positioning die 32 through the lifting bolt 33, and one side surface of the control block 21 is approximately moved to a position opposite to the surface of the reference plate 22. Releasing the abutting spring, the abutting spring pushes the reference plate 22 to abut against the side surface of the control block 21, and the reference plate 22 is attached to the side surface of the control plate. The piston rod of the fixed cylinder 61 is in an extension state, the positioning insertion block 62 is matched with the positioning insertion hole, and the piston rod of the jacking cylinder 81 is in a contraction state. The first blade 15 to be processed is placed on the mould cavity 43.

The sliding block 42 is moved towards the direction of the impeller hub 16, the blades 15 approach the impeller hub 16 along with the sliding block 42, when the blades 15 contact the impeller hub 16, the jacking cylinder 81 is started, so that the piston rod of the jacking cylinder 81 extends to drive the top plate 82 to jack the bottom of the sliding block 42, the sliding block 42 is prevented from sliding, and then the height of the blades 15 is adjusted through the telescopic sleeve 7.

The positioning bolt 73 is loosened and the second sleeve 72 is moved to adjust the total height of the telescopic tube 7. The blade 15 is brought to the appropriate welding height position. After the adjustment, the blade 15 is welded. Then the piston rod of the jacking cylinder 81 is contracted, the top plate 82 is separated from the slide block 42, and then the slide block 42 is pushed to reset.

The second blade 15 is placed on the mold cavity 43. Sliding the reference plate 22 in a direction away from the control block 21 to contract the biasing spring, rotating the control block 21 to rotate the next side of the control block 21 in a direction generally toward the reference plate 22, releasing the reference plate 22, and allowing the reference plate 22 to move toward the control block 21 and engage the second side of the control block 21 with the biasing force of the biasing spring. At this time, the three-jaw chuck 31 rotates along with the rotating shaft 24 by an angle equal to the angle difference between the adjacent blades 15, and the piston rod of the fixed cylinder 61 is controlled to extend so that the positioning insertion block 62 is inserted into the positioning slot 63, thereby preventing the control block 21 from moving up and down and rotating. Then, the sliding block 42 is moved to the vicinity of the impeller hub 16 along the slide rail 41, the second blade 15 is brought into contact with the hub 16, the piston rod of the abutting cylinder 81 is controlled to extend again so that the top plate 82 abuts against the sliding block 42 to prevent the sliding block 42 from sliding, and then the second blade 15 is welded. This is repeated until all the blades 15 are welded and the impeller is removed.

When the number of the blades 15 is different, the angle positioning work can be performed by replacing the control block 21 with the side prism shape corresponding to the number of the side faces.

The contraction amount of the tightening spring can be adjusted by rotating the adjusting bolt 13, thereby adjusting the tightening force of the tightening spring on the reference plate 22.

During operation, the height position of the operating platform 1 can be adjusted by simultaneously rotating the four supporting screws 19, so that the operation is convenient.
