Abstract
A system for constructing devices for chucking workpieces in defined and reproducible positions on machine tools and measuring machines includes a mounting pipe which has grid points formed at regular coordinate distances and is provided in the longitudinal direction of the pipe with chamfers uniformly distributed over the circumference, wherein the grid points are formed on the chamfers in the form of concave spherical recesses, and wherein the center points of the spherical recesses are located on lines which extend parallel to the chamfers outside of the pipe body and which describe the ideal pipe shape.
Claims5
A system for constructing devices for chucking workpieces in a defined and reproducible position, the system comprising:
- at least one mounting pipe having a longitudinal direction and a circumference, the mounting pipe having chamfers extending in the longitudinal direction and uniformly distributed over the circumference of the mounting pipe, wherein the mounting pipe has first concave spherical recesses provided in the chamfers and wherein the first concave spherical recesses define arid points of the mounting pipe located at regular coordinate distances, wherein the first concave spherical recesses have center points located on lines extending parallel to the chamfers and outside of the mounting pipe, wherein the lines describe an ideal shape of the pipe;
- a base plate having second concave spherical recesses having central points located on intersecting lines intersecting perpendicularly in accordance with a grid pattern, wherein the second concave spherical recesses define grid points of the base plate, which grid points of the base plate are located at regular coordinate distances matching the regular coordinate distances of the grid points of the mounting pipe, wherein the intersecting lines describe an ideal shape of the base plate;
- and
- a plurality of connecting elements each comprised of a hollow sphere having an outer diameter, wherein the first and second concave spherical recesses have a diameter, wherein the outer diameter of the hollow sphere is equal to the diameter of the first and second concave spherical recesses;
- the hollow sphere having a large insertion bore having a diameter greater than a diameter of a head of a fastening screw to be passed through the insertion bore, a first fastening bore located approximately opposite the insertion bore, a second fastening bore located at an angle of at least 90° relative to the first fastening bore, wherein the second fastening bore is located in a first plane with the insertion bore and the first fastening bore, and a small tool bore located in the first plane approximately opposite the first fastening bore.
