Rotary machining cutter

Abstract

The invention discloses a rotary machining cutter which comprises a rotary cutter body, wherein cutter slots are formed in the outer edge at the front end of the rotary cutter body; cutter holders are mounted in the cutter slots through cutter holder fastening components; cutting blades are mounted at the head parts of the cutter holders through cutting blade fasteners; adjusting structures are also mounted in the cutter slots; the adjusting structures are located between the tail part surfaces of the cutter holders and the tail part positioning surfaces of the cutter slots; all the surfaces, located between the tail part surfaces and the end surfaces of the cutter holders, of the cutter holders are circumferential surfaces of the cutter holders; each cutter holder fastening component comprises at least two cutter holder fasteners; and the cutter holders are locked by the cutter holder fasteners in different directions of the circumferential surfaces of the cutter holders. The rotary machining cutter provided by the invention has the advantages of positioning stability, strong vibration resistance, long service life, high machining precision 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 relatively common structure in the finishing tool in the...

In some processing occasions, the end or side runout 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 relatively common structure in the finishing tool of the prior art to set one or more tool pockets with a run-out adjustment structure in the tool holder. After the tool holder is provided with a run-out adjustment structure, The static accuracy of the tool holder can be improved after each adjustment, but the positioning scheme structure in the prior art and the multi-structure strength of the tool attachment are poor, and cutting vibration is prone to occur during cutting, resulting in inconsistent tool runout accuracy and static accuracy during cutting, which cannot achieve true accuracy. Low run-out finishing cutting in the sense
