CONTOURING TORQUE VICE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; treatment of complex-geometry parts. SUBSTANCE: vice has base, lead screw, moving and fixed hollow cases provided with sets of pins. Small balls engageable with rear parts of pins are placed in cases. Moving and fixed hollow cases have guide nets which limit pin displacement. Pins are stepped structures; smaller section of each pin is configured like guide net holes. Two springs are mounted on lead screw in moving case; nut with dowel engageable with moving case slot is installed between mentioned springs.
