Clamping Device For Clamping A Workpiece, And Installation Comprising Such A Clamping Device

An installation for working on a workpiece having a constant section, the installation comprising a structure, a tool device fixed on the structure, at least one clamping device for clamping the workpiece near the tool device, the clamping device comprising:

• a base fixed on the structure;
• a head;
• jaws comprising a lower jaw fixed to the base and an upper jaw facing the lower jaw and fixed to the head;
• a guide to link the head to the base and to allow displacement of the head in an action direction between a clamping position wherein the jaws define a clamping space having a constant section between them to clamp the workpiece, and an opening position wherein the jaws are opened allowing the lateral insertion of the workpiece between the jaws;
• the guide comprising at least two plates parallel one with the other, each plate having a first end linked to a heel of the base and a second end opposite the first end and linked to the head, the first end and second end being flexible to allow the plates to pivot in relation to the heel and the head, respectively the clamping device being in one block of monolithic material.

An installation for assembling two workpieces, each workpiece having a constant section, the installation comprising a structure, an assembling tool device fixed on the structure, a first clamping device for clamping a first of the two workpieces, a second clamping device for clamping the second of the two workpieces near the tool device, each clamping device comprising:

• a base fixed on the structure;
• a head;
• jaws comprising a lower jaw fixed to the base and an upper jaw facing the lower jaw and fixed to the head;
• a guide to link the head to the base and to allow the displacement of the head in an action direction between a clamping position, wherein the jaws define a clamping space having a constant section between them to grasp the workpiece, and an opening position wherein the jaws are opened allowing the lateral insertion of the workpiece between the jaws;
• the guide comprising at least two plates parallel one with the other, each plate having a first end linked to a heel of the base and a second end opposite the first end and linked to the head, the first end and second end being flexible to allow the plates to pivot in relation to the heel and the head, respectively
• the clamping device being in one block of monolithic material;
• the assembling tool device being located between the first and the second clamping devices, the installation comprising translation means to translate the second clamping device towards and outwards the first clamping device.
