The utility model turns on the switch of the motor, the motor drives the rotating shaft to rotate, the rotating shaft drives the gear to rotate, through the meshing of the gear and the tooth groove, the gear drives the slide bar to move along the horizontal direction, the slide bar drives the transmission block to move, the transmission block drives the transmission rod to move, the transmission rod drives the transmission frame to move, and the transmission frame drives the first clamping plate to move, so as to adjust the clamping distance between the first clamping plate and the second clamping plate according to impellers of different sizes, so as to avoid the impeller processing being affected to a certain extent due to the inability to position it according to impellers of different sizes.

[0004] Regarding the above-mentioned related technologies, the distance between the first clamping plate and the second clamping plate can be adjusted to fix the auxiliary impeller. However, during the use of the positioning tool, due to the inconsistent size of the central hole of the auxiliary impeller, it is inconvenient to fix the center of the auxiliary impeller. Only the left and right sides of the auxiliary impeller are restricted, which easily causes the auxiliary impeller to shake, resulting in a decrease in the surface processing quality of the auxiliary impeller and affecting the processing effect.

The center hole on the surface of the impeller structure 2 can pass through the column 172 and the fixing seat 171, and is supported by the turntable 12. A telescopic member 173 is arranged on the outer side of the fixing seat 171. The telescopic member 173 is used to support in the hole of the impeller structure 2 and cooperate with the clamping member 3 to locate the position of the impeller structure 2, which is beneficial to the subsequent processing of the impeller structure 2.

When the cylinder 1731 is in operation, the movable plate 1732 can be pushed to move, so that the movable plate 1732 can be close to the inner wall of the hole of the impeller structure 2 and squeezed, thereby fixing the impeller structure 2.

[0027] Four groups of telescopic members 173 are provided, and the four groups of telescopic members 173 are symmetrically distributed about the center line of the rotating disk 12 , and the four groups of telescopic members 173 are all used to restrict the impeller structure 2 .
