Composite cutter for drilling and boring hole and processing end surface annular groove

Abstract

The invention belongs to the field of part processing and particularly relates to a composite cutter for drilling and boring a hole and processing an end surface annular groove. A tool holder is installed on the top of a non-standard cutter body; drill blades are installed at the bottom of the non-standard cutter body; one drill blade is installed in a manner of passing through an axis of the non-standard cutter body, and the other drill blade is installed on the outer side of the non-standard cutter body; rough boring blades and radius boring blades are symmetrically installed on the outer side of the non-standard cutter body sequentially; a regulation cutter clamp is arranged above the radius boring blade on one side and is provided with a finish boring blade; chamfer blades are symmetrically installed on the outer side of the non-standard cutter body; and non-standard groove blades are arranged on the outer sides of the chamfer blades in a staggering manner respectively. By adoptingthe composite cutter provided by the invention, the cutter changing time and the cutter cost are saved, the processing efficiency is improved, and the processing cost is lowered; larger drilling force can be acquired at the same time, so that processing is lighter, the danger of drop-dead halt of the cutter is avoided, and the processing efficiency is improved; the inside and outside diameter sizes of the annular groove are more easily controlled, the quality is more reliably ensured, and the quality stability of parts is high when the parts are produced in batch.

Description

technical field [0001] The invention belongs to the field of component processing, and in particular relates to a composite cutter for drilling and boring holes and processing annular grooves on end faces. Background technique [0002] At present, the hole processing of parts is generally divided into four tools: drilling, rough boring, radius boring, and fine boring. Usually, in order to avoid hole flanging and burrs, a chamfering tool is added to deburr the hole. If there is an end surface The grooves will be processed by profiling with end mills, the processing efficiency is extremely low, and the quality is unstable, which cannot meet the high-yield and high-efficiency requirements of modern manufacturing in mass production. Therefore, in mass production, it is necessary to design a special composite tool to improve part quality and production efficiency. Contents of the invention [0003] The present invention aims to solve the above problems, and provides a composit...
