| 摘要 |
The present invention is related to a tool head for chip removing metal machining tools having a cutting insert (3), comprising a basic holder (1) and an insert holder (4) connected therewith, which in the front portion thereof is formed with an insert pocket (7), which is formed between a lower support part (6) and an upper clamping portion (5). The upper clamping portion (5) is actuatable by means of a press arrangement into clamping surface engagement with the cutting insert (3), which is insertable into the insert pocket, the tool being formed with a slot (20) spaced-apart from the insert pocket. The press arrangement comprises a clamping screw (19), which is received in a bore (15) in the basic holder, and a nut roll (11a) adapted to receive the clamping screw, the nut roll being received in a recess (10a) in the basic holder. The recess (10a) is oriented perpendicularly to the longitudinal direction of the cutting insert and the insert pocket. Upon co-operation with the clamping screw (19) during tightening of the clamping screw, the nut roll (11a) is adapted to be imparted movement substantially in the axial direction of the clamping screw radially outwards, such that the nut roll is displaced into said slot (20) and thereby accomplishes such a deflection of the upper portion of the holder that a clamping of the cutting insert (3) is accomplished by this deflection. <IMAGE> |
