A combined honing tool and method

Abstract

The invention discloses a combined type honing tool. The combined type honing tool comprises a honing cutter rod, a honing cutter and a rotary knob. A cutter handle is arranged at the tail of the honing cutter rod. The rotary knob is arranged on the honing cutter rod, and scales are arranged on the outer surface of the rotary knob. Threads are formed in the outer surface of one end of the honing cutter rod and the inner surface of one end of the honing cutter correspondingly. The honing cutter rod and the honing cutter are connected through the threads. A honing cutter frame is provided with a square hole. The surface of the honing cutter is designed to be a taper with a circular arc. A taper matching the taper of the horning cutter is designed for the honing cutter rod. The outer surface of the honing cutter is fastened to the honing cutter frame through an O-shaped ring. When a super-long deep-hole product is machined, the standardized honing cutter and the honing cutter rod are connected through the threads for splicing lengthening. The combined type honing tool has the advantages that the requirements of universalization, serialization and special conditions during product machining can be met. The invention further discloses a combined type honing method.

Description

technical field [0001] The invention relates to the aerospace field, more specifically it is a combined honing tool. The invention also relates to a combined honing method. Background technique [0002] In the field of high-end aerospace manufacturing industry, new products have higher and higher requirements for machining accuracy and surface quality, the size of products is getting larger and the structure of products is becoming more and more complex; the performance, size, appearance and other indicators of these products require The improvement has broken through the processing limit of the original equipment and cutting tools, and put forward higher requirements for the processing equipment and processing accuracy of the product. [0003] Most of the existing honing tools are general-purpose tools, which can meet the precision requirements of the product when processing holes of common specifications and lengths; but when processing ultra-long and ultra-deep holes in ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing honing tools are general-purpose tools, which can meet the precision requirements of the product when processing holes of common specifications and lengths; but when processing ultra-long and ultra-deep holes in the aerospace field, there are mainly some problems, which cannot meet the requirements of use. The demand is mainly reflected in: the length of the tool is insufficient to meet the needs of super long holes; when processing super long holes, it cannot meet the requirements of product accuracy, and there are often multiple clamping positioning, steps, and eccentric situations; the grinding tool is blindly lengthened , leading to the taper of the hole when processing the product, which cannot meet the requirements of product accuracy; there are many types of materials involved in the aerospace field, and different tools are required; most of the existing tools are forming knives or poor versatility, which is not easy to replace different Abrasive knives; in addition, one material is equipped with a series of knives, and the cost of use is too high
