Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.

Referring to fig. 1 to 2, the deformation-preventing rotatable workpiece table for impeller production includes a support frame 100 and a rotating table 200 rotatably disposed on the support frame 100, a plurality of positioning fixing members 300 are circumferentially disposed on the rotating table 200 at intervals, and the plurality of positioning fixing members 300 are distributed on circumferences of different diameters concentric circles with the rotating table 200 to fix impellers of different outer diameter sizes.

In this embodiment, a plurality of through holes 201 are circumferentially provided at intervals on the rotary table 200, and the positioning and fixing member 300 includes a fixing bolt 310 passing through the through hole 201 and a pressing plate 320 fixed to the rotary table 200 by the fixing bolt 310.

In order to increase the centering speed of the impeller and the installation speed of the impeller, a positioning and centering bolt 400 is arranged in the middle of the rotary worktable 200 so as to center and fix the impeller center plate 10.
