I-shaped slot is spaced 60 ° of settings on chuck, is disposed radially clamping boss in the middle part of the side wall of each I-shaped slot, sets in the middle part of each claw
Inserting groove compatible with clamping boss is set, so that each claw can be inserted into the I-shaped slot, the center setting of the chuck is suitable for
The central shaft hole that turbine wheel shaft passes through；It further include the limit base of 3 same structures, each limit base includes the curved wall being wholely set
And bottom wall, so that the section of limit base is L-shaped, the side-wall outer side of each limit base is arranged link block, and when assembly, each limit base was through even
It connects block to be fixedly linked with claw, so that each limit base forms a circular base, turbine wheel shaft group after each claw is inserted into corresponding inserting groove
The bottom end of part blade is supported by bottom wall, and the outside of blade carries out package limit by side wall, and turbine wheel shaft is inserted into central shaft hole, keeps away
Exempt to tilt when the assembly of turbine shaft assembly.
Further, each claw setting stage portion is so that the L-shaped setting in claw section, the interior wedge shape of inner end setting of each claw
Portion, outer wedge-shaped part is arranged in the outboard end of each claw can be by outer wedge-shaped part or interior wedge shape when so that the claw sliding in chuck
Portion's guiding；Each claw is inserted into the chuck backward step portion and is arranged higher than the top surface of the chuck, when assembly the bottom wall of limit base and
Link block is placed in the upper end of the stage portion, claw be inserted into after the chuck between bottom wall lower end surface and the top surface of chuck there are
Gap.
The technical effect of invention: turbine shaft assembly nose centre bore of the invention processes clamping tool, relative to existing skill
It in art, is matched using limit base with claw, so that limit base forms a circular base after claw is inserted into chuck, in chuck
Central shaft hole is arranged in the heart, so that the turbine wheel shaft of turbine shaft assembly can be inserted into central shaft hole, while the bottom end of blade is by circular base
Bottom wall be supported, the lateral surface of blade carries out clamping limit by the side wall of circular base, can effectively avoid turbine shaft assembly
It is tilted when assembly, finds center accurately when conducive to processing, greatly facilitate the processing of turbine wheel shaft centre bore.
