Adjustable fine boring cutter

Abstract

The invention relates to an adjustable fine boring cutter. The adjustable fine boring cutter comprises a cutter body, a cutter bit and a blade. A combining hole is formed in the head of the cutter body and provided with an internal thread at one end. A positioning plate, a fine adjustment screw and a dial are arranged on the head of the cutter body, an external thread is arranged on the positioning plate and meshed with the internal thread in the combining hole, and the positioning plate and the cutter body are fixed through a bonding agent. A threaded sleeve is arranged in the combining hole, one end of the threaded sleeve is connected with a copper nut through threads, and the threaded sleeve is meshed with insection of an insection groove in the end face of the cutter bit. An axial locking nut is arranged on the outer side of the cutter bit, sequentially penetrates through the cutter bit and the threaded sleeve and fixes the cutter bit and the threaded sleeve. One end of the fine adjustment screw is connected with the dial, and the other end of the fine adjustment screw is meshed with the copper nut through threads matched accurately. The fine boring cutter is high in rigidity, strength and cutting performance, the working radius can be finely adjusted fast, the boring cutting accuracy and the working efficiency can be improved, and the service life of the fine boring cutter is ensured.

Description

technical field [0001] The invention relates to the technical field of numerical control cutter manufacturing, in particular to an adjustable fine boring cutter. Background technique [0002] The fine boring tool is a kind of boring tool, which can be used on boring machines, lathes or milling machines for semi-finishing or finishing the existing holes. With the rapid development of industrial technology, fine-tuning fine boring tools are more and more used in production practice. In order to obtain high dimensional accuracy of the hole during boring, the working radius of the boring tool for finishing needs to be adjusted accurately. However, most of the fine-tuning and fine-boring tools produced in China are simply installed on the cutter body with the ready-made fine-tuning and fine-boring units. Due to the limitation of the fine-tuning and fine-boring units, this kind of fine-tuning boring tools has a small adjustment range and low adjustment accuracy. not tall. Obvio...
