Rotary processing tool

Abstract

The invention discloses a rotary processing process which comprises a rotary cutter body, wherein the outer edge of the front end of the rotary cutter body is provided with a cutter slot; a cutter holder is arranged in the cutter slot through a cutter holder fastener; the head part of the cutter holder is provided with a cutting blade through a blade fastener; a regulating structure is further arranged in the cutter slot; the regulating structure is positioned between the tail surface of the cutter holder and the tail positioning surface of the cutter slot; and when the regulating structure is used for regulating the position of the cutter holder, radial projection, relative to a moving direction of the rotary cutter body, of the cutter holder and a rotary centre shaft C of the rotary cutter body form an acute angle a. The rotary processing tool has the advantages of being simple in structure, high in regulating precision, capable of being used for finish processing, and the like.

Description

technical field [0001] The invention relates to the field of metal cutting, in particular to a rotary machining tool. Background technique [0002] With the development of the metal processing manufacturing industry, the requirements for the surface finish of the processing are getting higher and higher. In the cutting operation of the rotary tool with multiple cutting blades, in order to improve the surface finish of the processing, the end or side of the cutting blade is required to have Higher positioning accuracy. In some processing occasions, the runout of the end or side of the cutting blade on the rotary tool is required to reach 0.001mm, but due to the size of the cutter body and cutting blade of the rotary tool being limited by the manufacturing capacity and the existence of assembly clearance, the runout is difficult To achieve such a high precision requirement, in order to meet the processing needs, it is a common runout control method in the prior art to provide...

In some processing occasions, the runout of the end or side of the cutting blade on the rotary tool is required to reach 0.001mm, but due to the size of the cutter body and cutting blade of the rotary tool being limited by the manufacturing capacity and the existence of assembly clearance, the runout is difficult To achieve such a high-precision requirement, in order to meet the processing needs, it is a common run-out control method in the prior art to set one or more sipes with a run-out adjustment structure

[0003] Chinese patent CN100513032C discloses a runout adjustment structure, in which a screw is arranged on the positioning surface in the sipes, and the runout size of the cutting blade is changed by adjusting the position of the screw relative to the positioning surface. The above scheme has a simple structure and a large range of runout adjustment, but Due to the large size change when the screw enters and leaves the positioning surface, it is difficult to adjust the axial or radial dimensions of the cutting inserts in multiple sipes to the level of 0.001mm, and the adjustment takes a long time. At the same time, the thread is directly used between the screw and the positioning surface Cooperate with and directly contact with the cutting blade, which greatly reduces the positioning strength and rigidity of the groove, and the cutter body is prone to vibration during cutting, thus reducing the quality of the machined surface
