Abstract

The invention relates to a changeable and once-forming trimming chamfer cutter and a manufacturing process thereof, being particularly suitable for double-sided chamfering and deburring of through holes, composite holes and half through holes of various composite complex bodies. The device comprises a core shaft and a cutting tool which is arranged on the core shaft. The device is characterized in that the cutting tool is provided with a strip-shaped arbor and a knife head which is at one end of the arbor, the knife head is provided with a front cutting edge and a back cutting edge, the core shaft is opened with an elastic closed slot, the knife head is arranged in the elastic closed slot and a governing mechanism is arranged between the core shaft and the arbor of the cutting tool. Compared with the prior art, the invention has the following advantages: 1. the chamfer cutter has reasonable design and simple structure, and the cutting tool can be changed conveniently without any damage to work pieces, and the processed products have high precision. 2. chamfering and deburring of the two ends of the hole can be completed once with wide application range. 3. the chamfer cutter has simple processing technology, easy processing and manufacture and convenient assembly and disassembly.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a replaceable once-formed edge trimming and chamfering knife, which is especially suitable for double-sided chamfering and deburring of through holes, combined holes and half through holes of various combined complex bodies. Background technique [0002] In the processing of modern mechanical parts, parts, assemblies, and complex bodies that require through-hole processing are often chamfered by boring machines. However, the apertures are generally relatively large; lathes can also use longer tool bars to process some chamfers that can be used to clamp rotating parts, but these methods are difficult to achieve one-time molding, trimming, and chamfering of various apertures in the component body. horn. With the development of mechanical manufacturing technology, engineers and technicians are required to solve various mechanical manufacturing problems, and new requirements are...
