Description

Technical Field

[0001] The invention relates to the technical field of impeller welding, and in particular to a manufacturing and welding device for an axial flow fan impeller. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. A fan is a commonly used driven fluid machine. The fan impeller is the main component of the fan, and there are many types of fans that use impellers of different shapes. A common fan impeller is welded from a disk and blades, and the blades are circumferentially distributed with the center of the disk as the axis. During the ring welding process of the fan impeller, because the blades are in the direction of the disk axis and there is an inclination between the blades and the disk, it is necessary to use positioning parts in the welding device to clamp and restrict the blades and maintain stable support between the disk to ensure that the inclination of the blades is accurately positioned so that the blades are circumferentially distributed with the center of the disk as the axis. Since there are many blade shapes and the blades are arc-shaped, the curved surface structure of the blade and the positioning parts cannot be stably fitted during the clamping process, resulting in a distance between the positioning parts and the blades and loose contact, making it difficult to provide stable support, which causes the blades to easily slide or shift during the welding process, which is not conducive to the precise welding between the blades and the disk, and affects the quality of the welding completion.

It is flexible and convenient to use and can meet the use requirements of welding different blades 14.

[0028] Step 3: Then the servo motor 39 drives the second gear 35 to rotate along the installation groove 37, and then the second gear 35 drives the first gear 34 meshing with it to rotate in the offset groove 36. At this time, the rotation of the first gear 34 drives the stabilizing column 44, the connecting rod 32 and the sleeve 41 to rotate, and the rotation of the stabilizing column 44 drives the ear block 45 to rotate, and the ear block 45 and the abutment groove 47 abut and drive the movable ring 46 to rotate along the stabilizing ring 43, and the rotation of the stabilizing column 44 drives the limiting column 57 and the clamping column 51 to rotate along the inner wall of the connecting groove 33, so that the connection The connecting rod 32 rotates to drive the positioning member 13 and the adapting assembly 2 to fine-tune the angle at one end of the bogie 31, ensuring that the blade 14 maintains the correct position and posture during the welding process; and drives the steering assembly 3, the positioning member 13 and the adapting assembly 2 to move toward the wheel disc clamp 11 through the welding area workbench 1, and then the blade 14 is in contact with the wheel disc installed in the wheel disc clamp 11, so that the blade 14 and the wheel disc installed in the wheel disc clamp 11 maintain precise positioning, and at this time the welder 12 welds the blade 14 to the wheel disc installed in the wheel disc clamp 11 to complete the manufacturing welding operation of the impeller.
