Blade and clamp retainer with four-point contact

Abstract

The present invention involves a clamp holder (10) for cutting blade (20). Holding fingers (2), wherein the main (1) and clip fingers (2) are limited to the opposite sides of the groove (3) used to accommodate the cut blade (20). Among them One of the two sides of these sides has the first contact point and second contact point for cutting on one side of the cut blade, and there are third contact points on the opposite side, and it is used to limit the cutting blade (20) insertion The depth of the groove (3) depth (7) is set in the groove (3). In order to form the corresponding clamp holder and the suitable cutting blade for cutting blades, according to the present invention, it is recommended that the side of the third contact point of the cutting blade is assigned to stop the motion. At the same time, as a further fourth -sided contact point with the first contact point and the second contact point, and acting as the stop of the depth of the insertion of the cutting blade, the cut blade can withstand the relatively large cutting force, or even in it even in Under difficulty, under high cutting force, it can also ensure that the cutting blade is in a stable and safe position in the holder of the holder, and it can also reduce the vibration of the cutting blade during the processing of the workpiece and even reduce the cut blade generated by this cut blade. Early wear.

Description

technical field [0001] The invention relates to a clamping holder for cutting inserts having a rigid retaining part and clamping fingers elastically movable relative to the rigid retaining part, the retaining part and the clamping fingers defining a substantially On the opposite sides of the U-shaped groove for accommodating the cutting blade, and inside the groove, a stopper for limiting the depth of the cutting blade inserted into the groove is provided. In this case, the side opposite the clamping finger has at least two contact points spaced apart from each other or correspondingly extending contact surfaces, the contact surface comprising at least two such contact points, and the clamping finger having one contact point Or a less extended contact surface to engage the cutting insert. Background technique [0002] Corresponding clamping holders for cutting inserts, in particular for so-called insert / insert plates, have been known for a long time. These clamping holders...

Problems solved by technology

In this case, the cutting blade can in some cases be completely released from its seat part, but it will change position at least for a short time, so the condition of the cutting edge changes, the cutting surface may become dirty, or further Generates increased forces, which can cause vibration and corresponding early wear, and can also cause the cutting insert to split from its seat, or cause the cutting insert to break
