Mechanical-clamping non-indexable outer embedded knife tool

Abstract

The invention relates to a mechanical-clamping non-indexable outer embedded knife tool. The knife tool comprises an outer embedded knife blade, an outer embedded knife base, an outer embedded knife pad and a fastening screw. An outer embedded knife base knife containing groove is matched with the outer embedded knife blade, and the outer embedded knife blade and the outer embedded knife base are rapidly positioned through two positioning faces forming an angle of 100 degrees and clamped through the fastening screw to form the outer embedded knife tool via mechanical-clamping holes. The outer embedded knife tool is inserted into an outer embedded knife tool knife containing groove in the surface of the head of a knife body through the handle part of the outer embedded knife base, the positioning faces are in interference fit to clamp the outer embedded knife tool, and the thickness of the outer embedded knife pad is adjusted so as to adjust the machining diameter of the outer embedded knife blade so that the requirements for diameters of different machined holes can be met. High-temperature welding is not needed, the structure is simple, installing, operating and adjusting are convenient, the machining quality and machining efficiency of deep holes are improved, the manufacturing and using costs of the knife tool are lowered, and the mechanical-clamping non-indexable outer embedded knife tool can be widely applied to the field of machining of deep holes of various sizes and depths.

Description

technical field [0001] The invention relates to a deep hole processing tool, in particular to a machine-clamp type non-indexable external insert tool for deep hole drilling. Background technique [0002] The outer insert cutters of high-speed deep hole drills currently on the market include traditional heat-welded cutters and indexable machine-clamped cutters. [0003] The outer insert blade and the outer insert seat of the traditional heat welding tool are connected by artificial heat welding to form the outer insert assembly. There are problems such as the possibility of stress and cracks caused by high temperature welding, poor consistency of tool geometry, complicated loading and unloading operations, and high cost of tool production and use. The geometrical parameters of the cutting edge and the groove shape of the chip breaker are processed and formed according to the specific conditions of the workpiece to be processed after the outer insert assembly is f...

AI Technical Summary

Problems solved by technology

The indexable machine holder tool is a fool’s tool, and the blade is formed at one time. There are problems such as the technical strength of the operator cannot be fully utilized, the processing speed is fixed, about 90mm / min, the adjustable range of processing is small, about 0.5mm, and the cost of the tool is high.

[0005] The shortcomings of the above two cutting tools restrict the efficiency and application of deep hole processing to a certain extent.
