RADIAL-HINGE-DRILLING MACHINE Russian patent published in 2008 - IPC B23B39/12 

FIELD: technological processes; mechanics.

SUBSTANCE: machine contains vertical column installed on base, which bears rotary bracket, drive of measuring turn that includes tooth gears, and drive of longitudinal displacement, which includes mechanism that contains tooth gear for displacement of rotary bracket in vertical direction for regulation of its level in relation to processed part, and spindle unit that contains gearboxes and feeding boxes. It is equipped with rotary axis installed on rotary bracket in the form of shaft that may rotate with preset speed, in which spindle unit is fixed, and clamp arranged in column and made together with casing of mechanism for displacement of rotary bracket. At that rotary bracket rotary bracket is made of top and bottom parts that are connected by means of comb-shaped joint that provides for its displacement along column axis and rotation around it, at that top part is connected to the mentioned mechanism of displacement by means of screw.

EFFECT: expansion of technological resources.
