Description

Main pin hole inner hole chamfering tool

Technical Field

The utility model belongs to the technical field of chamfering tools, and particularly relates to a main pin hole inner hole chamfering tool.

Background

In the field of machining, chamfer cutting is an important processing technique, such as: the chamfer is processed at the interface of the workpiece, so that not only can burrs at the interface of the workpiece be removed, but also the contact area of the interface of the workpiece can be increased, and the assembly of the workpiece is simpler; the chamfering of the inner hole of the main pin hole of the workpiece in the prior art is not convenient enough, and after the chamfering of one side of the workpiece is completed, the workpiece needs to be taken down and turned over, so that the other side of the workpiece can be chamfered, and the time for processing the workpiece is greatly increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a main pin hole inner hole chamfering tool, which solves the existing problems: the chamfering of the inner hole of the main pin hole of the workpiece in the prior art is not convenient enough, and after the chamfering of one side of the workpiece is completed, the workpiece needs to be taken down and turned over, so that the other side of the workpiece can be chamfered, and the time for processing the workpiece is greatly increased.

In order to solve the technical problems, the utility model is realized by the following technical scheme: the inner hole chamfering tool for the main pin hole comprises a tool handle, wherein a machining end is arranged at one end of the tool handle, and a positive chamfering structure and an inverse chamfering structure are installed on one side of the machining end.

Further, the positive chamfer structure comprises a first tool mounting body and a positive chamfer insert;

the first tool mounting body is mounted in the middle of one side of the machining end, and a positive chamfering blade is mounted inside the first tool mounting body.

Further, the reverse chamfer structure comprises a second tool mounting body and a reverse chamfer blade;

the second cutter mounting body is mounted at one end of one side of the first cutter mounting body, and a reverse chamfering blade is mounted inside the second cutter mounting body.

Further, the reverse chamfering blade and the positive chamfering blade are identical in structure and are symmetrically arranged.

The utility model has the following beneficial effects:

according to the utility model, the inner holes on two sides of the workpiece can be directly chamfered by the chamfering tool through the relative arrangement of the forward chamfering blade and the reverse chamfering blade, and the chamfering of the other side of the workpiece can be carried out without reversing the workpiece, so that the processing time of the workpiece is reduced.
