Abstract:
A fixing device for fixing a linearly displaceable machine part relative to a fixedly supported machine part, comprising:a guiding block adapted to receive a bar member passing through the guiding block through guiding means, said guiding means having a longitudinal central axis, said guiding block including a controllable setting device and clamping members, said setting device having longitudinal operating axis and said clamping members including through-holes for receiving the bar member, said clamping members, in the guiding block, being settable by the setting device, between a first position in which said clamping members clamp the bar member and a second position in which the clamping members release the bar member, the clamping members comprising:a plurality of congruent plate elements with parallel surfaces in said first position, said plate elements assuming corresponding angular positions relative to the central axis of the bar guiding means and, in the second position, said plate elements being located so as to be approximately normal relative to the central axis of the bar guiding means and said plate elements being supported for moving between said angular positions by abutments which are positioned in a plane, comprising the central axis of the bar guiding means and lying perpendicularly to another plane being defined by said central axis and said operating axis.
