Abstract

A tool-holder including: a first rail and a second rail that are parallel and each of which includes first fixing elements configured for fixing said rail to the surface, a driving slide including first guiding elements configured to slide over the first rail, a drive system configured to move the driving slide along the first rail and a first fixing system, a driven slide including second guiding elements configured to provide a sliding connection with the second rail and a second fixing system, an assembly bar carrying a first complementary fixing system cooperating with the first fixing system to form a removable fixing between them, a second complementary fixing system intended to cooperate with the second fixing system to form a removable fixing between them, and a carriage having a first assembly system, and a movement system on which the carriage is fixed and that is configured to move said carriage along the assembly bar, and a support module including second fixing elements for fixing the tool and a second assembly system intended to cooperate with the first assembly system to form a removable fixing between them.

First claim

The invention is:

1 . A tool-holder configured to be fixed to a surface of a workpiece and to carry a tool, said tool-holder comprising:
a first rail and a second rail that are parallel and each of which includes first fixing elements configured to fix one of the first and second rails to the surface; a driving slide including first guiding elements that have a guiding position in which said first guiding elements are configured to provide a sliding connection between the driving slide and the first rail; a drive system configured to move the driving slide along the first rail; a first fixing system; a driven slide including second guiding elements that have a guiding position in which said second guiding elements are configured to provide a sliding connection between the driven slide and the second rail and a second fixing system, an assembly bar a first end of which carries a first complementary fixing system intended to cooperate with the first fixing system to form a removable fixing between them, a second end of which carries a second complementary fixing system intended to cooperate with the second fixing system to form a removable fixing between them, a carriage having a first assembly system, and a movement system on which the carriage is fixed and that is configured to move said carriage along the assembly bar, and a support module including second fixing elements for fixing the tool and a second assembly system intended to cooperate with the first assembly system to form a removable fixing between them, wherein each of the first and second guiding elements includes at least three grooved wheels, at least two of which are disposed along a first longitudinal edge of the first rail, respectively second rail, and at least one of which is disposed along a second longitudinal edge of the first rail, respectively second rail, wherein for each of the first or second guiding elements, at least one group from said at least two grooved wheels or said at least one grooved wheel is movable from the guiding position to a releasing position in which said at least one group is at a distance from the rail, and wherein the corresponding slide includes an actuating system configured to move said at least one group from the guiding position to the releasing position and vice versa, wherein for each of the first and second guiding elements, the actuating system includes a handle that can be moved from a locking position to an unlocking position and, for the movable grooved wheels, an offsetting system mobile between a guiding position in which said grooved wheels are in the guiding position and a releasing position in which said grooved wheels are in the releasing position, and a transmission system configured to drive the movement of the offsetting system from the guiding position to the releasing position when the handle is manoeuvred from the locking position to the unlocking position and vice versa, and wherein for one of the first and second guiding elements, the handle takes the form of a trigger, wherein the transmission system includes a cable connecting the trigger to the offsetting system, and wherein the offsetting system includes: an actuator with a rod, an offsetting arm having a first end connected to the cable and on which the actuator is rotatedly mounted and a second end rotatably mounted on the chassis, a first arm rotatably mounted on the chassis and articulated to the rod, a second arm one end of which is mounted on and articulated to the first arm, and a third arm rotatably mounted on the chassis and carrying the grooved wheel, and wherein the other end of the second arm is mounted on and articulated to the third arm.

2 . The tool-holder according to claim 1 , wherein for the other of the first and second guiding elements, the handle is a rotary knob, wherein the transmission system is a shaft rotatable about a transmission axis, fastened to the rotary knob and the second offsetting system, and
wherein the offsetting system includes: a first hub rotatable on the chassis and fixed to the shaft and the rotation axis of which is offset relative to its centre and coincides with the transmission axis, the grooved wheel being rotatably mounted on the first hub, a second hub rotatable on the chassis and the rotation axis of which is offset relative to its centre, the grooved wheel being rotatably mounted on the second hub, a fixed shaft around which the second hub is rotatably mounted, and a link the first end of which is rotatably mounted on the first hub to rotate about an axis parallel to the transmission axis and the second end of which is mounted on the second hub to rotate about an axis parallel to the transmission axis.

3 . The tool-holder according to claim 1 , wherein the second rail has slots, wherein the driven slide includes a tooth and a security system configured to insert the tooth in a slot when the assembly bar is released from said driven slide and to extract the tooth from the slot when the assembly bar is fixed to said driven slide or if intentionally activated.

4 . The tool-holder according to claim 3 , wherein the security system includes:
a security shaft rotatably on the driven slide to rotate about an axis parallel to the plane of the second rail; a lever fixed to the security shaft a first end of which projects relative to the driven slide and a second end to which the tooth is articulated, a return mechanism configured to urge the lever into the position in which the first end projects relative to the driven slide, and a security handle fixed to the security shaft.

5 . The tool-holder according to claim 1 , wherein the first fixing system or the second fixing system includes a stud with a head, the axis of which is perpendicular to the plane of the rail and wherein the first complementary fixing system or the second complementary fixing system includes an attachment system comprising:
two jaws, each mounted on the chassis to rotate about a clamping axis parallel to the plane of the rail between a clamping position in which the jaws grip the head and a free position in which the jaws release the head for each jaw, a return device configured to urge said jaw into the clamping position, and a release system configured to move the two jaws from the clamping position to the free position.

6 . The tool-holder according to claim 1 , wherein the first fixing system or the second fixing system includes a plurality of orifices and a threaded rod the axes of which are parallel to the direction of the rail and wherein the first complementary fixing system, respectively the second complementary fixing system, includes:
for each orifice, a protuberance adapted to be inserted in the orifice, and a threaded hole adapted to receive the threaded rod.

7 . The tool-holder according to claim 6 , wherein the plurality of orifices and the threaded rod are disposed on a plate that is mounted on the slide and mobile in translation in a direction perpendicular to the longitudinal direction of the rail and parallel to the plane of the rail.

8 . The tool-holder according to claim 1 , wherein the carriage includes a base fixed to the movement system, a mobile support mounted on the base to rotate about a tool axis parallel to the longitudinal direction of the assembly bar, stop means for stopping the rotation of the mobile support, and the first assembly system arranged on the mobile support.

9 . The tool-holder according to claim 8 , wherein the support module includes a base carrying the second assembly system, a drawer mounted on the base to move in translation in a direction perpendicular to the plane of the rails, actuating means for moving the drawer on the base, and wherein the se
