Base unit for releasably fixing workpiece supports

A combination of a base unit for releasably fixing workpiece supports, wherein each of the workpiece supports comprise at least one clamping bolt, and at least one of the workpiece supports comprising one clamping bolt of the at least one clamping bolts, the base unit comprising the following:

• a base plate;
• a cover plate, which is provided with cover plate through-openings through each of which one clamping bolt of the at least one clamping bolts of one workpiece support of the workpiece supports can pass;
• a fixing element, which is provided with fixing element through-openings through each of which the one clamping bolt of the one workpiece support can pass, and
• by which the one clamping bolt of the one workpiece support is fixable to the base unit when the fixing element is located in a working position;
• and
• a movement device for moving the fixing element at least one of i) from a rest position into the working position and ii) from the working position into the rest position,
• wherein the fixing element comprises resiliently held clamping frames on each of which at least one of the fixing element through-openings is arranged and wherein each of the clamping frames is held on a basic body of the fixing element by one or more resiliently elastic arms.

A base unit for releasably fixing workpiece supports, wherein each of the workpiece supports comprise at least one clamping bolt,

• wherein the base unit comprises the following:
• a base plate;
• a cover plate, which is provided with cover plate through-openings through each of which one clamping bolt of the at least one clamping bolts of one workpiece support of the workpiece supports can pass;
• a fixing element, which is provided with fixing element through-openings through each of which the one clamping bolt of the one workpiece support can pass, and by which the one clamping bolt of the one workpiece support is fixable to the base unit when the fixing element is located in a working position;
• and
• a movement device for moving the fixing element at least one of i) from a rest position into the working position and ii) from the working position into the rest position,
• wherein the movement devices comprises a screw with a head that is stationarily mounted in an axial direction of the screw relative to at least one of the cover plate and the base plate of the base unit.
