Patent ID: 7806632

Claim:
A clamping assembly, comprising a cutting insert and a clamping device for clamping the cutting insert on a bearing surface provided on a tool holder, which clamping device comprises a slide including a guide segment, intended to be slidably mounted in a guide hole provided in the bearing surface, and a clamping segment including a clamping head comprising a lateral clamping relief with such a shape that it has a clamping contact surface, at least partially turned toward the guide segment, so as to abut an opposite seat surface, associated with a cavity in the cutting insert leading to at least one bearing face of the cutting insert and arranged so as to house the clamping segment, so as to clamp the cutting insert against the bearing surface when the cutting insert and the slide are mutually arranged in a mutually relative clamping position, whereby the cavity of the cutting insert has a passage template, along an access passage for passing the head from the bearing face to the seat surface, the seat surface being associated exclusively with one side of the cavity, wherein the passage template varies according to a suitable shape which is adapted, with respect to a bulk template of the lateral clamping relief, so that the passage template is incompatible with the bulk template when the cutting insert and the slide are arranged in said mutually relative clamping position, and said suitable shape is adapted so that the passage template is compatible with the bulk template when the cutting insert and the slide are arranged in at least one other mutually relative position, for release of the cutting insert, wherein the guide hole is formed in an oblique direction of extension toward a plane of extension of a lateral wall limiting the bearing surface, wherein the cavity has a symmetrical shape with respect to a median plane located at a half-thickness level of the cutting insert, wherein the cavity also leads, through another passage having said passage template, to a face opposite said bearing face and wherein the cavity comprises another seat surface for clamping the cutting insert, which is reversible, in the overturned position.
