A positioner for turbine rotor impeller central axis

A positioner for turbine rotor impeller central axis, it relates to a rotor blade wheel the central axis's positioner. The turbine rotor impeller needs artificial manual put forward the gauge outfit to draw at double -column boring machine, race milling machine processing alignment rotor Z axle during zero point, should carry the displacement error that the pulling easily caused the table skeleton, is difficult to fix a position rotor blade wheel the central axis's position. The utility model discloses the connecting piece assembly sets up between turbine rotor cutterhead groove and lathe main shaft, the first connecting block of top fixedly connected with of connecting axle, be equipped with the connecting rod in the adapter sleeve, the other end of adapter sleeve is connected with the one end of adjusting the pole, the other end of adjusting the pole is connected with the second connecting block, the stiff end of length measurement instrument passes through the second fastener and connects on the second con
