Abstract
A tool holder (1) in the form of a boring head, a chuck, a milling cutting arbor, or the like, is equipped with a damping element (2) in the form of an elongated body that is arranged in an end housing (3) of the tool holder (1), with corresponding shape and size. The tool holder that is characterized in that it includes a device (4) for preventing excessive heating of the damping element (2). The tool holder is more particularly applicable in the field of numerically-controlled machine tool accessories, machining centers, and flexible cells and workshops.
Claims20
A tool holder, comprising:
- an outer first part (1) having a rear end and an opposite front end, the front end having a sleeve (5) that accommodates one of a group consisting of a boring head, and a milling cutting arbor;
- an end housing (3) within the outer first part;
- a damping means (2) in the form of an elongated body, the damping means (2) being arranged in the end housing (3) and having a shape and a size corresponding to a shape and a size of the end housing, the damping means (2) having a first end towards the front end of the outer first part and a second end towards the read end of the outer first part;
- and
- a device (4) for preventing excessive heating of the damping means (2), the device (4) being positioned between first end of the damping means (2) and the sleeve (5) such that the device (4) for preventing excessive heating provides a shield that covers an entirety of the first end of the damping means (2) in a plane perpendicular to a longitudinal axis of the tool holder at the first end of the damping means (2).
A tool holder, comprising:
- an outer first part (1) with a sleeve (5) that accommodates one of a group consisting of a boring head, and a milling cutting arbor;
- an end housing (3) within the outer first part;
- a damping means (2) in the form of an elongated body, the damping means (2) being arranged in the end housing (3) and having a shape and a size corresponding to a shape and a size of the end housing;
- and
- a device (4) for preventing excessive heating of the damping means (2), wherein, a length of the end housing (3) is greater than a length of said damping means (2), and the prevention of excessive heating is carried out by a movement of the damping means (2) from i) an operating position, in which the damping means (2) is placed and is held at one end of the end housing (3), near the sleeve (5), to ii) a position for preventing the heating in which the damping means (2) is placed and is held at the opposite end of the end housing (3).
A tool holder (1), comprising:
- an outer first part (1) with a sleeve (5) that accommodates a boring head;
- a housing (3) within the outer first part;
- a damping means (2) having an elongated body, the damping means (2) being arranged in the housing (3), a length of the housing (3) being greater than a length of the damping means (2);
- and
- a device (4) for preventing excessive heating of the damping means (2), wherein the prevention of excessive heating is carried out by a movement of the damping means (2) from i) a first operating position in which the damping means (2) is placed and is held at a first end of the housing (3) near the sleeve (5), to ii) a second position for preventing the heating in which the damping means (2) is placed and is held at an opposite second end of the housing (3).
