Patent attributes
A tool holder for clamping an insert holder has a main block, two clamping members and a single adjustment member. The main block has a longitudinal side surface with a longitudinal groove with upper and lower walls. The two clamping members include mirror symmetrical left and right clamping members interfacing with two inclined non-parallel planar ramping surfaces of the lower wall of the longitudinal groove. A blade-shaped insert holder is mounted in the longitudinal groove on the two clamping members. The adjustment member interfaces with the two clamping members, and when rotated causes each clamping member to move up its respective non-parallel planar ramping surface, decreasing the distance between the two clamping members and the upper wall of the longitudinal groove until a clamping force is uniformly applied between the insert holder and the upper wall of the longitudinal groove.
