Abstract
A tool clamping device having a tool holder (2) holding a tool (7, 8) for insertion into a socket of a tool support (1), such as a turret disc is designed such that a receiving body (16) of the tool holder and the tool support (1) have bearing surfaces (16, 3) to be arranged to one another and devices (14, 15) for fastening the tool holder on the tool support. The receiving body or the tool support has at least one stopping means (28), which projects axially over its bearing surface and is disposed on one side of the receiving body or tool support. The tool support or the receiving body has at least one contact surface for the stopping means. There is provided elastic means (36, 44) by means of which the stopping means can be laterally held in place on the contact surface under prestress.
Claims39
A tool clamping device comprising
- (a) a tool support (1) having at least a socket (4) comprising, a bearing surface (3) facing outwardly from said socket;
- (b) at least a tool holder (2) having a receiving body (16), said receiving body (16) having a bearing surface (18) engaged to the bearing surface (3) of said tool support,
- alignment means for positionally accurate adjustment of said tool holder and its receiving body in relation to said tool support, said alignment means including,
- a stop strip means (28) connected to one of said receiving body (16) or said tool support (1), said stop strip means having at least a flat surface (30)
- a contact surface (35) on one of said tool support (1) or of said receiving body (16),
- said stop strip means extending beyond the joined bearing surface (18) of the receiving body (16) and the bearing surface (3) of said tool support (1), said stop strip means (28) having an insertion means to facilitate attachment of the receiving body (16) to the tool support (1), and
- elastic means (36, 44) for holding said stop strip means (28) laterally under prestress on said contact surface (35).
A tool clamping device comprising
- (a) a tool support (1) having at least a socket, a bearing surface (3) facing outwardly from said socket and a contact surface (35) extending from said bearing surface (3) in a direction away from and substantially perpendicular to said bearing surface (3);
- (b) a tool holder (2) having a receiving body (16), and a coupling body (17) extending therefrom, said receiving body (16) having a bearing surface (18) engaged to the bearing surface (3) of said tool support and a receiving surface (23) substantially perpendicular to its bearing surface (18) said coupling body (17) extending into said socket along a path substantially perpendicular to said receiving body (16) bearing surface
- (c) alignment means for positionally accurate adjustment of said tool holder and its coupling body in relation to said tool support, said alignment means including,
- (d) a stop strip means (28) connected to one of said receiving body (16), said stop strip means having a pair of parallel flat surfaces (30), one of said flat surfaces (30) engaged to said receiving surface (23) of said receiving body (16) and said contact surface (35) of said tool support (1) and extending beyond the joined bearing surface (18) of the receiving body (16) and bearing surface (3) of said tool support (1), said stop strip means (28) having wedge-shaped bevels (31) each extending from one of said flat surfaces (30) and tapering inwardly toward one one another to thereby facilitate attachment of the receiving body (16) to the tool support (1), and
- elastic means (36, 44) for holding said stop strip means (28) laterally under prestress on said contact surface (35).
A tool holder (2) that is adapted to be mounted on a tool support (1), comprising
- a housing-shaped receiving body (16) having an outwardly facing bearing surface (18) located on its outside and configured to mount said tool holder with its bearing surface positioned onto a corresponding bearing surface of said tool support, one of a stop strip means (28) or a contact surface (35) on one side of and adjacent to that bearing surface, said stop strip means (28) having at least a flat surface (30) extending beyond said bearing surface (18) for engagement with a contact surface on said tool support, said stop strip means (28) having insertion means to facilitate attachment of the receiving body (16) to said tools support (1), and
- said tool holder comprising elastic means (36, 44) for holding said stop strip means (28) laterally under prestress on a contact surface (35) of a tool support when the receiving body (16) is attached to said tool support.
