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

Embodiment 1

[0024] Example 1: Such as figure 1 As shown, a special multifunctional combined tool for processing stepped holes includes a tool holder 1 and a blade. The end of the tool holder 1 away from the blade is tapered. The blade includes an end processing blade 6 and a radial processing blade 7. The end of the tool holder 1 is provided with a clamping groove 2 and a drill bit positioning hole. The drill bit positioning hole is located at the axis of the tool holder 1, and a drill bit 12 is installed in the drill bit positioning hole. The clamping groove 2 includes a first clamping portion and a second clamping portion. The first clamping portion is used for fixing the end processing blade 6 and the second clamping portion is used for fixing the radial processing blade 7. Such as image 3 As shown, the first clamping portion and the second clamping portion are respectively located on both sides of the drill positioning hole, the first clamping portion is located on the cross-sectional ...

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 special for processing stepped holes. Background technique [0002] The existing method of processing stepped holes is to use multiple drills of different diameters to drill in layers, but this type of processing method requires the replacement of the drill bit according to the diameter of each stepped hole at different stages, and the steps cannot be completed at one time. Hole processing. There is also a method of cutting by installing a blade on the tool holder. This type 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 wo...
