The support 11 supports the fixing plate 12, the adjusting rod 2 and the tooling table 3. The fixing plate 12 is combined with the support 11 and the fixing shaft 13 by conventional methods. The adjusting rod 2 rotates 90 degrees around the fixing shaft 13, which can change the angle between the adjusting rod 2 and the impeller skeleton A, facilitating the machining of the impeller skeleton A at different angles; a positioning component for placing the impeller skeleton A, including a tooling table 3 connected to the top end of the adjusting rod 2, a fixing stud 31 integrally cast at the center position of the tooling table 3, and a locking cylinder column 4 screwed to the fixing stud 31. The fixing stud 31 passes through the positioning hole at the center of the impeller skeleton A. Tighten the locking cylinder column 4 to firmly connect the locking cylinder column 4 with the fixing stud 31, thereby realizing the limitation of the impeller skeleton A and facilitating the machining of its two side surfaces; a limiting component, including a lifting circular plate 5 slidably sleeved outside the adjusting rod 2, a lifting rod 6 passing through the circular edge position of the lifting circular plate 5, a pressing plate 7 connected to the top end of the lifting rod 6, and a compression spring 8 sleeved outside the lifting rod 6. The pressing plate 7 is combined with the lifting rod 6 by conventional methods. Symmetrically distributed stop posts 71 are provided on the bottom surface of the pressing plate 7. After the impeller skeleton A is placed on the tooling table 3, lift the pressing plate 7 to move the lifting rod 6 upward, and the compression spring 8 is in a compressed state. Rotate the pressing plate 7 around the lifting rod 6, lower the pressing plate 7 and make it fit with the circular edge position of the impeller disc a1 of the impeller skeleton A. The stop posts 71 limit the circular edge of the impeller disc a1 to prevent the impeller disc a1 from skewing.

[0025] In this embodiment, the fixing plate 12 is a "U"-shaped structure, a stabilizing circular plate 21 is provided on the outer side of the bottom end of the adjusting rod 2, the fixing shaft 13 passes through the center of the stabilizing circular plate 21, the adjusting rod 2 and the stabilizing circular plate 21 rotate in the same direction, and a hand-tightening locking screw 121 passes through the opposite surface of the fixing plate 12, and the hand-tightening locking screw 121 is a "Y"-shaped structure. The hand-tightening locking screw 121 locks the stabilizing circular plate 21, so that the adjusting rod 2 and the stabilizing circular plate 21 with changed angles are in a stable state, which is conducive to processing the impeller skeleton at different angular positions, a convex column c is provided on the outer surface of the stabilizing circular plate 21, and a convex column b is provided on the opposite surface of the fixing plate 12, the convex column a is tangent to the outer surface of the convex column c, and the blocking column 71 limits the circular edge of the impeller disk a1 to prevent the impeller disk a1 from deflecting.

[0028] In this embodiment, the clamping plate 7 is curved, and the impeller skeleton A includes an impeller disk a1 with a positioning hole at the center and an arc-shaped blade a2. There is a certain distance between the curved end of the blade a2 extending outward and the outer surface of the impeller disk a1, which does not affect the clamping plate 7 clamping the circular edge of the impeller disk a1. The blocking column 71 is tangent to the outer surface of the impeller disk a1, and the blocking column 71 limits the circular edge of the impeller disk a1 to prevent the impeller disk a1 from tilting.

[0032] The locking cylinder 4 is locked, so that the locking cylinder 4 is firmly connected to the fixing stud 31, thereby limiting the impeller skeleton A, which is beneficial for processing the two sides thereof;

[0033] The adjusting rod 2 rotates 90 degrees around the fixed shaft 13, which can change the angle between the adjusting rod 2 and the impeller skeleton A, so that the adjusting rod 2 and the stabilizing circular plate 21 with the changed angle are in a stable state, which is beneficial to processing the impeller skeletons at different angular positions;
