TRANSFER MACHINE Russian patent published in 1996 - IPC

FIELD: machine-tool manufacture. SUBSTANCE: transfer machine has unit-type spindle heads 2 with drive for feeding from hydraulic cylinders 3, curbstone 3 with power table 4 mounted on it and additional hydraulic cylinders. Supports 6 and 7 are placed on table 4. During reciprocal displacements of power table 4 supports 6 and 7 interact by turns with oppositely placed plungers 13 and 14 of additional hydraulic cylinders mounted in pairs opposite to each other. In this case during displacement of power table 4 according to the cycle: fast feed - effective feed - fast removal, unit-type spindle heads 2 perform analogous cycle as working cavities of each pair of additional hydraulic cylinders are connected with working cavities of hydraulic cylinder 3 for feeding one of unit-type spindle heads 2 with endurance of rigid support. Supports 6 and 7 placed on power table 4 are made spring-loaded. In case any of unit-type spindle heads 2 must have two working feeds the working cavities of hydraulic cylinder for feeding this head are connected with working cavities of at least two pairs of additional hydraulic cylinders. EFFECT: enhanced efficiency. 2 cl, 6 dwg
