Honing tool and honing stick
A honing tool includes a tool body which is tubular at least in certain portions and includes a cutting region with at least one honing stick receiving opening which is continuous from the interior of the tool body to the outside and is intended for receiving a honing stick, wherein dimensions of the honing stick receiving opening and of the honing stick are matched to one another such that the honing stick is received radially movably, and substantially without play in the circumferential direction of the tool body, between boundary surfaces of the honing stick receiving opening. The honing tool comprises a honing stick retaining system designed such that the honing stick is held in the honing stick receiving opening by the honing stick retaining system.
1 . A honing tool comprising:
a tool body that is tubular at least in certain portions and comprises a cutting region with at least one honing stick receiving opening which is continuous from an interior of the tool body to outside and is adapted to receive a honing stick,
wherein dimensions of the honing stick receiving opening and the honing stick are matched to one another such that the honing stick is received radially movably, and without play in a circumferential direction of the tool body, between boundary surfaces of the honing stick receiving opening,
a honing stick retaining system comprising at least one elastically compressible retaining element and in an installed state of the honing stick engages, with a pressing force generated by compressing the retaining element, on a boundary surface of the honing stick receiving opening such that the honing stick is held in the honing stick receiving opening by the honing stick retaining system,
wherein the honing stick has at least one through-opening in a guide portion that interacts with the honing stick receiving opening, and the at least one elastically compressible retaining element is disposed in the at least one through-opening, and
the at least one elastically compressible retaining element is configured, in the installed state of the honing stick, to engage, with the pressing force generated by compressing the at least one elastically compressible retaining element, on two mutually opposite boundary surfaces of the honing stick receiving opening such that the honing stick is held in the honing stick receiving opening by the honing stick retaining system;
wherein the at least one elastically compressible retaining element is in the form of a ball of an elastically deformable material.
2 . The honing tool as claimed in claim 1 , wherein the honing stick has a width in the region of the through-opening, and the at least one elastically compressible retaining element, in an absence of external compressive forces, has a length greater than the width, with the result that the at least one elastically compressible retaining element can be inserted into the at least one through-opening such that, in introduced and relaxed states, the at least one elastically compressible retaining element projects beyond a side surface of the honing stick at both ends of the through-opening.
3 . The honing tool as claimed in claim 1 , wherein the at least one elastically compressible retaining element which, in a relaxed state, has an outside diameter greater than an inside diameter of the at least one through-opening such that the at least one elastically compressible retaining element can be introduced into the at least one through-opening with elastic deformation and, in the introduced state, is automatically captively held in the at least one through-opening by frictional engagement.
4 . The honing tool as claimed in claim 1 , wherein the at least one elastically compressible retaining element is formed exclusively by one or more balls of the elastically deformable material.
5 . The honing tool as claimed in claim 1 , wherein the at least one elastically compressible retaining element comprises precisely one ball of the elastically deformable material, and the ball in a relaxed state has a diameter greater than an inside diameter of the at least one through-opening.
6 . The honing tool as claimed in claim 5 , wherein the honing stick in the region of the at least one through-opening has a width which is less than the diameter of the ball, with the result that the ball can be inserted into the at least one through-opening such that, in an introduced state, the ball projects beyond a side surface of the honing stick at both ends of the at least one through-opening.
7 . The honing tool as claimed in claim 1 , wherein a through-opening of the at least one through-opening of the honing stick has a length in a width direction greater than an inside diameter of the through-opening, and the at least one elastically compressible retaining element comprises multiple balls of the elastically deformable material which can be inserted into the through-opening in a row, diameters of the multiple balls are greater than the inside diameter of the through-opening such that the multiple balls are held in the through-opening, and a sum of the diameters of the multiple balls is greater than a length of the through-opening in the width direction such that the multiple balls in the row project beyond the through-opening on each side.
8 . The honing tool as claimed in claim 1 , wherein the at least one through-opening comprises multiple through-openings, two or three through-openings distributed over a length of the honing stick, and a respective at least one elastically compressible retaining element is disposed in each of the multiple through-openings.
