| 摘要 |
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. |
