Abstract
In an interface arrangement between a first component group supporting a tool holder and a second component group supporting a machining element in a central opening for releasably accommodating the first component group, a shift lever element provided with engagement members is disposed rotatably on the second component group and provided with engagement and release elements for releasably retaining the first component group in the central opening of the second component group so as to permit a rapid exchange of the first component group by another group with a new tool.
Claims8
In an interface arrangement formed by a first component group (20) supporting a tool or a tool holder and a second component group (90) carrying a machining element (120),
- the first component group (20) having a central opening (30) with a truncated cone-shaped section (31) with a circular cross-section and contact points or a contact area (24) effective in an axial direction, that is in a direction toward the second component group (90) and
- the second component group (90) having a cone- or truncated cone-shaped section (110) for abutting the truncated cone-shaped section (31) of the first component group (20), and
- at least one contact or engagement area (93) facing in axial direction for contact or engagement with the contact area (24) of the first component group (20),
- the improvement wherein a shift lever element (60, 61) is longitudinally movably or pivotally supported in the central opening (30) of the first component group (20),
- the shift lever element (60, 61) is of an annular shape and has at least two transverse bores (81, 82) and the first component group (20) includes at least two engagement pins (41, 55) extending into the transverse bores (81, 82) for supporting the shift lever element (60, 61) and has linking webs (71, 72) for connecting the second component group (90) to the first component group (20) and
- the second component group (90) includes an engagement element (105, 106) which, by a pivot movement of the second component group (90), engages the linking webs (71, 72) of the shift lever element (60, 61).
An interface arrangement between a first component group (20) supporting a tool or a tool holder and a second component group (90) supporting a machining element,
- the first component group (20) having a central opening (30) which has at least one truncated cone-shaped section (31) with circular cross-section and
- the second component group (90) having a conical or truncated cone-shaped section (110) to be in contact with the truncated cone-shaped section of the first component group (20),
- a shift lever element (60, 61) being disposed in the central opening (30) of the first component group (20) so as to be movable therein in a longitudinal direction and also being pivotable,
- the shift lever element (60, 61) being annular and having at least two transverse bores (81, 82) and the first component group (20) having at least one engagement member (71, 72) with pins (41, 55) extending into the transverse bores (81, 82 for supporting the shift lever element (60, 61) and providing a connection to the second component group (90) and
- the second component group (90) having at least one engagement element (105, 106) which, by a pivot movement of the second component group (90), is engageable with the at least one engagement member (71, 72) of the shift lever element (60, 61).
