Grooving cutter

Abstract

The invention relates to a grooving cutter which comprises a cutter blade and a cutter body, wherein the cutter body comprises a supporting part and a clamping part, and a cutter groove used for mounting and dismounting the cutter blade is arranged between the supporting part and the clamping part; the clamping part is provided with a clamping part front end, a clamping part limiting end and a clamping part rear end, the clamping part front end and the clamping part limiting end are separated through a front narrow groove, and the clamping part rear end is separated through a rear narrow groove; both the clamping part front end and the clamping part rear end have independent elasticity, and the clamping part limiting end is positioned above the clamping part front end. The grooving cutter has the advantages of being simple in structure, stable in clamping and high in supporting intensity and realizes multipoint clamping positioning.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a grooving tool. Background technique [0002] In the metal cutting processing industry, the blade is subjected to a large cutting force during the cutting and grooving process, resulting in a large cutting vibration. Usually, the clamping of the blade by the tool is concentrated on the part of the blade near the cutting edge, so that the During the cutting process, the rear end of the blade vibrates greatly, the clamping reliability is not high, and the tool is prone to wear and deformation, which affects the machining accuracy of the part. [0003] U.S. Patent No. 6,234,727B1 discloses a cutting tool. The first clamping surface of the tool can elastically move around the first elastic axis of rotation, and the second clamping surface can elastically move around the second elastic axis of rotation. The first clamping surface is opposite to the blade. The upper front end o...

[0003] U.S. Patent No. 6,234,727B1 discloses a cutting tool. The first clamping surface of the tool can elastically move around the first elastic axis of rotation, and the second clamping surface can elastically move around the second elastic axis of rotation. The first clamping surface is opposite to the blade. The upper front end of the blade applies a clamping force, and the second clamping surface applies a clamping force to the upper rear end of the blade. Only when the first elastic axis and the second elastic axis are in line, the first clamping surface and the second clamping surface If the first elastic axis and the second elastic axis of rotation are not collinear, then the first clamping surface and the second clamping surface are not independent of each other, the degree of independence depends on the first elastic axis and the second elastic axis The closeness of the tool and the blade is greatly restricted. While ensuring the reliability of the clamping, it is difficult to ensure the complete independence of the two clamping surfaces.
