A blade 9 is arranged between the profiling positioning piece 7 and the positioning rod 8. An impeller rear cover plate 10 is fixedly provided at the top of the blade 9. A positioning component 11 for positioning the impeller rear cover plate 10 is provided on the positioning main board 5. A clamping mechanism 12 for strengthening the fixing of the positions of the positioning component 11 and the blade 9 is provided on the positioning main board 5. A pressing plate 13 is fixedly provided on the impeller rear cover plate 10. Second cylinders 14 are symmetrically provided on the top of the bottom plate 2. The output ends of the second cylinders 14 are fixedly provided with abutting rods 15 for abutting against the pressing plate 13. A detection mechanism 16 for detecting the welding position of the blade 9 and the impeller rear cover plate 10 is fixedly provided on the top of the base 1 near one side of the bottom plate 2. First, start the first cylinder 4 to raise the device to the height required for operation. Take the blade 9 to be welded and place it inside the positioning main board 5.

After placing, place the impeller rear cover plate 10 on the top of the blade 9 and concentric with the blade 9. After placing, position the impeller rear cover plate 10 through the positioning component 11. After fixing, strengthen the components of the blade 9 and the positioning component 11 through the clamping mechanism 12. Finally, place the pressing plate 13 on the impeller rear cover plate 10, and adjust the height of the abutting rod 15 through the second cylinder 14 so that the abutting rod 15 fixes both sides of the top of the pressing plate 13, thereby realizing the welding of the blade 9 and the impeller rear cover plate 10 through multi-directional fixing. After welding, the detection mechanism 16 is used to detect whether the centers of the welded blade 9 and the impeller rear cover plate 10 are consistent.

[0034] Among them, the positioning component 11 includes a positioning ring 111 and an abutting plate 112. The positioning ring 111 is fixedly positioned with the positioning main board 5.

By winding the clamping ring 121 around the positioning ring 111 and passing the positioning plug 122 through the card slot, the inclined cutting surface of the positioning plug 122 abuts against the side wall of the blade 9, thereby strengthening the fixation of the position of the blade 9. And the positioning plug 122 can be moved inside the chute 123 to adjust the position of the positioning plug 122, and further fix the blades 9 at different angles.

[0036] The detection mechanism 16 is used to detect whether the centers of the welded blade 9 and the impeller rear cover plate 10 are consistent. The detection mechanism 16 includes a first electric push rod 161, a detection plate 162, a positioning member 163 for positioning the welded blade 9, and a detection member 164 for detecting the welding position of the blade 9 and the impeller rear cover plate 10.

[0037] Among them, the positioning member 163 includes a positioning vertical rod 1631, a second electric push rod 1632, and an abutting arc plate 1633. The positioning vertical rod 1631 is fixedly arranged at the center of the detection plate 162. The number of the second electric push rods 1632 is multiple and they are evenly arranged along the circumferential direction of the positioning vertical rod 1631. The abutting arc plate 1633 is fixedly arranged with the output end of the second electric push rod 1632. The welded impeller rear cover plate 10 is placed on the positioning member 163. Since the cross-sectional shape of the impeller rear cover plate 10 is set as an inverted triangle, the center of the impeller rear cover plate 10 is placed on the positioning vertical rod 1631. By starting the second electric push rod 1632 to drive the abutting arc plate 1633 to abut and fix the inner wall of the impeller rear cover plate 10 at various angles.

[0038] Secondly, the detection piece 164 includes a protective ring 1641, a third electric push rod 1642, a fourth electric push rod 1643, a first arc-shaped plate 1644, a second arc-shaped plate 1645, a third arc-shaped plate 1646, an L-shaped rod 1647 and a measuring plate 1648. There are multiple third electric push rods 1642, which are fixedly arranged between the protective ring 1641 and the detection plate 162, and the output end of the third electric push rod 1642 is fixedly arranged at the bottom of the protective ring 1641. The protective ring 1641 and the detection plate 162 have the same center of the circle. There are four fourth electric push rods 1643, which are evenly arranged along the circumferential direction of the protective ring 1641, and the output ends of the fourth electric push rods 1643 extend into the protective ring 1641. The first arc-shaped plate 1644 is fixedly arranged at the output end of the fourth electric push rod 1643. The second arc-shaped plate 1645 is slidably arranged inside the first arc-shaped plate 1644 through a return spring. The third arc-shaped plate 1646 is fixedly arranged on the bottom wall of the first arc-shaped plate 1644. The L-shaped rod 1647 is fixedly arranged at the top of the second arc-shaped plate 1645. The measuring plate 1648 is fixedly arranged on the first arc-shaped plate 1644, and a groove for sliding the L-shaped rod 1647 is formed on the measuring plate 1648. After the welded blades are fixed, the third electric push rod 1642 is started to drive the protective ring 1641 to rise, so that the detection piece 164 corresponds to the position of the welded blade 9. The third electric push rod 1642 is started to drive the first arc-shaped plate 1644 to move, so that the third arc-shaped plate 1646 squeezes and fixes the rear cover plate 10 of the impeller. If the centers of the rear cover plate 10 of the impeller and multiple blades 9 are not at the same point, the position of the blade 9 will protrude outside the rear cover plate 10 of the impeller. Therefore, while the third electric push rod 1642 moves, the second arc-shaped plate 1645 will be squeezed by the protruding blade 9 and retract, driving the L-shaped rod 1647 to retract and slide on the measuring plate 1648, and further the approximate value of the deviation angle of the blade 9 can be obtained.
