Abstract
Device for coupling in a reproducible position two coupling elements, comprising a first coupling element (2) and a centering plate (4), the centering plate (4) being designed to be fastened to a second coupling element (3), the first coupling element (2) comprising at least one peg (21) comprising at least one spherical portion, the centering plate (4) comprising at least one hollow portion (41) working with the peg (21) during the coupling of said second coupling element (3) to said first coupling element (2) so as to determine the position of said centering plate (4) relative to said first coupling element (2), and equipment for pre-adjusting machine tools comprising this device.
Claims17
Device comprising a first coupling element and a centering plate, said centering plate being designed to be fastened to a second coupling element to ensure the reproducible positioning of said second coupling element onto said first coupling element, said first coupling element comprising at least three pegs, said centering plate lying in a plane and comprising at least three hollow portions working with one of said at least three pegs during the coupling of said second coupling element to said first coupling element so as to determine the position of said centering plate relative to said first coupling element,
- each one of said at least three pegs comprising at least one spherical portion,
- wherein around each one of said at least three hollow portions a flexible zone is demarcated by at least one notch and connected to the rest of said centering plate by two torsion zones allowing the pivoting of said flexible zone about an axis in said plane relative to the rest of said centering plate and out of the plane of the centering plate on each side of said axis when said first coupling element is fastened onto said second coupling element.
Device comprising a first coupling element and a centering plate of generally constant thickness, said centering plate being designed to be fastened to a second coupling element to ensure the reproducible positioning of said second coupling element onto said first coupling element, said first coupling element comprising at least three pegs, said centering plate lying in a plane and comprising at least three hollow portions, each one of said at least three hollow portions working with one of said at least three pegs during the coupling of said second coupling element to said first coupling element so as to determine the position of said centering plate relative to said first coupling element,
- each one of said at least three pegs comprising at least one spherical portion,
- wherein around each one of said at least three hollow portions a flexible zone is demarcated by at least one notch and connected to the rest of said centering plate by two torsion zones allowing the pivoting of said flexible zone about an axis in said plane relative to the rest of said centering plate and out of the plane of the centering plate on each side of said axis when said first coupling element is fastened onto said second coupling element.
Equipment for pre-adjusting machine tools, designed to work with a reference surface of a pre-adjusting machine and comprising at least one gauge, the position of said at least one gauge relative to said reference surface being precisely determined,
- said at least one gauge being fastened to a pallet capable of being coupled removably and reproducibly to a chuck designed to be fastened onto said reference surface,
- said equipment further comprising a centering plate designed to be fastened onto said pallet to ensure the reproducible positioning of said pallet onto said chuck, said chuck comprising at least three pegs, said centering plate lying in a plane and comprising at least three hollow portions, each one of said at least three hollow portions working with one of said at least three pegs during the coupling of said pallet to said chuck so as to determine the position of said centering plate relative to said chuck, each one of said at least three pegs comprising at least one spherical portion,
- wherein around each one of said at least three hollow portions a flexible zone is demarcated by at least one notch and connected to the rest of said centering plate by two torsion zones allowing the pivoting of said flexible zone about an axis in said plane relative to the rest of centering plate and out of the plane of the centering plate on each side of said axis when said first coupling element is fastened onto said second coupling element.
