A REFERENCING DIVICE FOR HMC TO MILL OFF TECHNOLOGICAL MATERIALS FROM LOCK TYPE-TURBINE BLADES

摘要

The invention relates to a referencing device for HMC to mill off technological materials from lock type-turbine blades, comprising : a locating member having a vertically placed base plate provided with hexagonal threaded holes for inserting of one each fixing bolt and referencing bolt, a vertical column absent of a projected portion fixed to the base plate at a horizontal plane; and referencing member having a holding plate vertically located, a referencing bolt movably placed at upper end of the holding plate, and a fixing bolt fixed at lower end of the holding plate, wherein the locating member locates the referencing member at the opposite side of the lock type turbine blade when placed on a horizontal machining center (HMC), and wherein the referencing member takes reference at root end near fillet area so that the technological allowances can be milled off by the HMC.
