Positioning unit for use with a production robot has a displaceable shaft that has two drive sections linked by a coupling so that the drive section holding a component mounting unit can be supported in a precision bearing

摘要

Small component positioning unit for mounting on a moving element of a production robot has a housing (1), a shaft (4) that can be moved rotationally and translationally, rotary (2) and linear (3) drives and a mounting unit (18) for holding a small component that is to be positioned. The shaft is divided into two drive sections (15, 16) that are linked by a coupling (17). The rotary drive drives the first drive section with force coupled to the second section via the coupling. The second section is guided into an independent precision bearing (11).
