Abstract
The present invention relates to a fastening tool for dynamically fastening parts for machining, said tool being formed by an annular frame (1) which is fastened to a rotary supporting means (2) arranged around the location of the machining tool (4) on a tool-holder head (3). The annular frame (1) incorporates a tamper formed by a rotating ball (5) and, in a diametrically opposite position, a tilting clamp (6) which incorporates a counter-tamper formed by another rotating ball (8). According to the invention, a cantilevered portion (9.1) of a part can be seized between the balls (5) and (8) of the tamper and counter-tamper in order to prevent bending and vibrations in relation to same during machining.
Claims3
A fastening tool for dynamically fastening a part for machining to prevent bending and vibrations of cantilevered portions of the part, the fastening tool comprising:
- a tool-holder head comprising:
- a machining tool;
- and
- a rotary support coupled to the tool-holder head, the rotary support being arranged proximate the machining tool;
- a single annular frame detachably coupled to the rotary support, the annular frame comprising:
- a first rotating ball;
- and
- an articulated assembly including a clamp comprising a second rotating ball wherein the clamp is adapted to move between a first position in which the first rotating ball is separated from the second rotating ball, and a second position in which the first rotating ball is proximate to the second rotating ball,
- wherein the clamp has an actuator cylinder that allows tilting the clamp between a position in which the first rotating ball and the second rotating ball are separated and a position in which the first rotating ball and the second rotating ball apply pressure on one another.
