This allows for the clamping and fixing of the impeller blank. Several sets of threaded holes 7 are evenly spaced inside the chuck 1, and are distributed in four equal parts on the surface of the chuck 1. A plane adjustment assembly 8 is installed inside each threaded hole 7. The plane adjustment assembly 8 includes a mounting stud 9, which is threadedly connected to the threaded hole 7. An adjusting stud 11 is installed on the upper part of the mounting stud 9, and is integrally formed with the mounting stud 9. An adjustment surface is provided on the surface of the adjusting stud 11. The adjusting sleeve 12 is threadedly connected to the adjusting stud 11. A top plate 14 is provided on the surface of the adjusting sleeve 12. By rotating the adjusting sleeve 12, its height on the surface of the adjusting stud 11 can be adjusted so that it comes into contact with the impeller blank held between the movable jaws 3. This can quickly correct the runout of the impeller blank. In use, select the appropriate threaded hole 7 according to the size of the impeller blank and install the flat adjustment assembly 8. The exposed length of the flat adjustment assembly 8 can be adjusted according to the actual situation so that the top plates 14 of the four sets of flat adjustment assemblies 8 are on the same plane, thereby realizing the rapid correction of the impeller blank plane.

[0019] Further improvements, such as Figure 1 As shown: The movable jaw 3 is arranged in a stepped structure, which increases the contact area between the movable jaw 3 and the impeller blank, thereby improving the stability and reliability of clamping.

[0020] Further improvements, such as Figure 2As shown: The chuck 1 is provided with several sets of circumferentially distributed fixing bolts 4 inside. The fixing bolts 4 are used to firmly install the chuck 1 on the processing equipment to ensure that the chuck 1 will not loosen or shift when rotating at high speed or subjected to large cutting forces.

[0024] Working principle: The impeller blank is placed between the movable jaws 3 of the chuck 1. By rotating the adjusting component 6, the movable jaws 3 move in the movable slots 2, adjusting the distance between the movable jaws 3 to clamp the impeller blank, ensuring that the impeller blank is firmly fixed on the chuck 1. This provides stable support for subsequent plane correction and machining, improving the stability and safety of the machining process and preventing the impeller blank from sliding or shifting during machining. According to the size and shape of the impeller blank, a suitable threaded hole 7 is selected, and the mounting stud 9 of the plane adjustment component 8 is screwed into the threaded hole 7. The plane adjustment component 8 is firmly installed on the chuck 1, providing a basis for subsequent plane correction and realizing flexible installation and removal of the plane adjustment component 8, which is convenient for impellers of different sizes. The blank is adjusted by rotating the adjustment knob 13, which moves the adjustment sleeve 12 on the adjustment stud 11 to adjust the height of the top plate 14 so that it contacts the surface of the impeller blank. By adjusting the height of the top plate 14 of the four sets of plane adjustment components 8, they are made to be on the same plane, thereby achieving rapid correction of the impeller blank plane, improving the flatness of the impeller blank, ensuring processing accuracy and surface quality, and reducing the adjustment and correction work in subsequent processing. After the plane correction is completed, the processing equipment is started to perform cutting, grinding and other processing operations on the impeller blank. Since the impeller blank has been firmly fixed and the flatness has been corrected, high precision and stability can be maintained during processing, improving processing efficiency and quality, reducing scrap rate and saving production costs.
