CLAMPING DEVICE Russian patent published in 2017 - IPC B25B5/12 B23Q3/06 

FIELD: machine building.

SUBSTANCE: invention relates to processed parts clamping devices. Clamping device (10) includes housing (12) and drive unit (14), having piston (32) moving in axial direction as result of fluid medium supply under pressure. On housing (12) clamping lever (16) is installed, supported with possibility of free turning. Piston rod (34) in drive unit (14) is connected with possibility of mounting/dismantling relative to moving force transfer mechanism (18) movable part (58), installed inside housing (12). Due to piston rod (34) connecting element (54) extraction from movable part (58) coupling element (64) drive unit (14) and moving force transfer mechanism (18) are output from one with another connection state.

EFFECT: invention usage allows to simplify drive unit replacement for possible clamping force changing.
