Title:
【発明の名称】遠心力によって締め付ける工具とスピンドルから成るセット
Document Type and Number:
Japanese Patent JP2003516239
Kind Code:
A
Abstract:
A description is given of a set (10) consisting of a spindle (1) and tool (2) for machining operations to remove shavings by means of rotation, wherein the clamping of tool (2) is accomplished by the action of centrifugal force acting on one or more of the parts that comprise the set, whereby said spindle (1) ends in a cylindrical cavity (3), inside of which is coaxially secured a cylindrical member (5), whose part that faces tool (2) has one or more diametral cuts (6) that divide it into two or more symmetrical portions (5s, 5t) that are able to bend outward in the radial direction under the action of centrifugal force, and wherein tang (7) of said tool (2) ends in a hollow cylindrical tube (7e) that is able to accommodate at least part of said portions (5s, 5t) of said cylindrical member (5), the walls of which have a thickness (S) that is equal to distance (D) between interior wall (3k) of said cylindrical cavity (3) of spindle (1) and the exterior wall of said cylindrical member (5), whereby during the above-mentioned machining operations tool (2) is clamped by the action of the radial outward bending of said portions (5s, 5t) of the latter which, by pushing on the interior surfaces of said hollow cylindrical tube (7e), deform it elastically and cause it to adhere to said interior wall (3k) of said cylindrical cavity (3) of spindle (1).
