FIELD: machinery building, particularly control devices for manual operation of processing tool movement. SUBSTANCE: driver unit has bar connected to base through ball and socket joint, arm mounted on bar and performing movement along its axis, three levers, three pairs of spring-loaded support members, three pairs of sensors. Two levers are connected with bar and located perpendicular thereto. Sensors monitor levers move along three coordinates. Spring-loaded support members and sensors are installed into sleeves adjusted along support member axes and may cooperate with each other in stroke end of support members. Holder is fixed to ball and socket joint from the side opposed to arm. The third lever is installed along holder axis. One end of the third lever cooperates with arm, another end of the third lever cooperates in turns with each pair of spring-loaded supporting members. EFFECT: increased unit operational reliability. 2 dwg |
