MECHANICALLY ACTUATED DEVICE, IN PARTICULAR, MILLING DEVICE Russian patent published in 2018 - IPC B23C5/26 B23Q3/14 

FIELD: machine building.

SUBSTANCE: invention relates to mechanically actuated devices. Device comprises drive shaft configured to rotate in the housing, which projecting from the housing second end carries disk-shaped tool, with the axial hole placed on the fixed to the shaft disk unit with annular clamping elements, which, by means of the clamping facility, can be pressed against the tool hole wall with forced closing. Drive shaft is made with open to the second end channel, into which a thrust member is inserted, which in its first end area is connected to the clamping facility, and in the second end area is with passing across the drive shaft pin, which radially projects beyond the drive shaft. Between the pin projecting areas and the bearing, spring package is clamped, and between the pin projecting areas and the bearing axially movable piston is located, which, with supply of pressure through the working medium input, can move towards the drive shaft second end against the spring package spring force.

EFFECT: enabling the tool constant clamping force and possibility of its quick change.
