A positioning system for positioning a positioning unit along a longitudinal axis includes: a linear guide arrangement for enabling a linearly guided motion parallel to the axis; a motor includes a moving motor member operatively connected to the linear guide arrangement and an elongated stationary motor member extending parallel to the axis; and a force transmission arrangement operatively connecting the moving motor member to the positioning unit, wherein the force transmission arrangement is arranged to provide a semi-rigid engagement between the positioning unit and the moving motor member, wherein the positioning unit and the moving motor member, respectively, are operatively connected to the linear guide arrangement by at least two guide engaging carriages, and wherein the positioning unit is attached to the guide engaging carriages by rigid or resilient positioning unit holders.

Positioning system for positioning a positioning unit along a longitudinal axis

This invention relates to a positioning system for positioning a positioning unit along a longitudinal axis. The positioning system comprises a linear guide arrangement for enabling a linearly guided motion parallel to said axis, wherein the positioning unit is operatively connected to said guide arrangement. Furthermore, the positioning system comprises a motor, wherein the motor comprises a moving motor member operatively connected to said linear guide arrangement and an elongated stationary motor member extending parallel to said axis. The moving motor member is adapted to move along the stationary motor member for providing motion parallel to said axis. Moreover, the positioning system further comprises a force transmission arrangement which operatively connects said moving motor member to the positioning unit. The force transmission arrangement is arranged to provide an engagement between said positioning unit and said moving motor. The engagement is rigid in a direction parallel to said axis for instantaneous transmission of a linear force, and is resilient in directions other than said direction parallel to said axis, whereby transmission to the positioning unit of forces arising from thermal expansion of the motor is reduced or eliminated.

A mechanical interface for transferring a reciprocating movement from one element to another element releasably mountable thereto. The interface comprises at least three interface points, at least two of which being laterally spaced apart, and at least two of which being longitudinally spaced apart. A motion generator provides a reciprocating movement, which is transferred from the one element to the other element via at least one of the interface points. The interface point(s) transferring the movement includes contact portions having curved contact surfaces, such that the curved contact surfaces are in abutment with opposing contact surfaces of the interface point when the elements are mounted, thereby transferring the reciprocating movement.
