Abstract
In a tool coupling in the form of a cutting tool used for internal machining operations, a second component having a single cutting portion is clamped to a first component by means of a clamping screw. The second component has a mounted surface with three male engaging members interfacing with three female engagement members on a mounting surface of the first component. Each of the three female engagement members has two sets of side surfaces located on a shared portion, the shared portion exhibiting mirror symmetry about a first plane, and each set of side surfaces having two opposing flank surfaces separated by the first plane. Only one of the two flank surfaces of each of the two sets of side surfaces is in clamping contact with a corresponding abutment surface on each of the three male engaging members.
Claims19
A tool coupling (20, 120) comprising a first component (22), a second component (24) and a clamping member (26) for clamping the first (22) and second (24) components together:
- the first component (22) having a mounting surface (30) provided with a longitudinal axis (A1) and at least three female engagement members (32);
- and
- the second component (24) having a mounted surface (34) with at least three male engaging members (36) interfacing with the at least three female engagement members (32),
- wherein each of the at least three female engagement members (32) has a first plane (P1) and at least two sets of side surfaces (46, 48), the at least two sets of side surfaces (46, 48) located on at least a shared portion (58) of their respective female engagement member (32), and the shared portion (58) exhibiting mirror symmetry about its respective first plane (P1),
- wherein each of the at least two sets of side surfaces (46, 48) has two opposing flank surfaces (50, 52;
- 54, 56) separated by their respective first plane (P1), and
- wherein only one of the two flank surfaces (50, 52;
- 54, 56) of each of the at least two sets of side surfaces (46, 48) is in clamping contact with a corresponding abutment surface (64, 66) on each of the at least three male engaging members (36).
