Multifunctional combined tool special for machining of stepped holes

Abstract

The invention relates to a machining tool, in particular to a multifunctional combined tool special for machining of stepped holes. The multifunctional combined tool special for machining of stepped holes comprises a tool holder and blades. The blades include an end machining blade and a radial machining blade. One end of the end machining blade and one end of the radial machining blade are provided with stepped hole machining teeth in step forms. The end of the tool holder is provided with a clamping channel and a bit positioning hole. A bit is disposed inside the bit positioning hole. The clamping channel comprises a first clamping part used for clamping the end machining blade and a second clamping part used for clamping the radial machining blade. The first clamping part locates on the diametric section of the tool holder. The lower end face of the second clamping part and the upper end face of the first clamping part locate in a same plane. One end of the end machining blade, close to the radial machining blade, is parallel to the axis of the tool holder. The multifunctional combined tool has the advantages that the diametric part of each segment of a stepped hole can be machined once, and the end face and diametric part of the stepped hole can be machined at the same time.

Description

technical field [0001] The invention relates to a processing tool, in particular to a multifunctional combined tool for processing stepped holes. Background technique [0002] The existing method of processing step holes is to use multiple drill bits with different diameters to drill holes in layers, but this kind of processing method needs to replace the drill bits according to the diameter of each step hole at different stages, and it is impossible to complete the steps at one time. Hole processing. Another method is to install the blade on the tool holder for cutting. This kind of processing method not only needs to replace the blade according to the diameter of each step hole at different stages, but also needs to use different when processing the end face and diameter of the step hole. The blade cannot complete the simultaneous processing of the end face and diameter of the stepped hole at one time, resulting in cumbersome processing procedures and increasing the workl...

Problems solved by technology

[0004] The present invention is mainly aimed at the need to replace the blade according to the diameters of different stages of the stepped hole in the existing step hole processing method, which cannot simultaneously process the end face of the stepped hole and the diameter of each stage at the same time, the processing procedure is cumbersome, the workload is large, and the blade is worn out It can only be replaced, etc., providing a method that can complete the machining of the diameter of each stage of the stepped hole at one time, and can complete the simultaneous processing of the end face and diameter of the stepped hole, can position the blade and the tool, and can process the axis at one time. Stepped holes with small diameter through holes, simplified processing procedures, avoid frequent replacement of blades, reduce workload, improve work efficiency, and avoid waste of blades Multi-functional combined tool for processing stepped holes
