Abstract

The utility model discloses a bidirectional chamfering device, which comprises a blade and a tool handle; the end part of the knife handle is provided with a screw hole and a knife groove, and the length of the knife handle is greater than the depth of the through hole to be processed; the blade is fixed in the cutter groove of the cutter handle through a screw and comprises an upper cutting edge and a lower cutting edge, and the upper cutting edge and the lower cutting edge are intersected at one point and are distributed at 90 degrees. Therefore, the bidirectional chamfering device can realize the processing of chamfering the front and back surfaces of the through hole under the condition of not replacing the cutter and turning over the workpiece.

Description

Bidirectional chamfering device

Technical Field

The utility model relates to the field of machining, in particular to a bidirectional chamfering device.

Background

The chamfering is a conventional process in machining, and when a workpiece in a through hole shape is chamfered, one end of the workpiece is firstly processed, then the workpiece is fixed in a reversed direction, and the chamfering processing of the other end is not convenient enough.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: a bidirectional chamfering tool is provided to improve the chamfering efficiency of a through hole-shaped workpiece.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:

a bidirectional chamfering device comprises a blade and a tool handle;

the end part of the knife handle is provided with a screw hole and a knife groove, and the length of the knife handle is greater than the depth of the through hole to be processed;

the blade is fixed in the cutter groove of the cutter handle through a screw and comprises an upper cutting edge and a lower cutting edge, and the upper cutting edge and the lower cutting edge are intersected at one point and are distributed at 90 degrees.

Compared with the prior art, the utility model has the following technical effects:

the processing of the front and back chamfers of the through hole can be realized under the condition that the cutter is not replaced and the workpiece is overturned, and the chamfer processing efficiency is improved.

FIG. 1 is a schematic structural diagram of a bidirectional chamfering apparatus according to the present invention;

in the drawings, the parts names represented by the respective reference numerals are listed as follows:

1. a blade; 2. a knife handle.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

Fig. 1 is a schematic structural diagram of a bidirectional chamfering apparatus according to the present invention. The bidirectional chamfering device comprises a blade and a tool handle;

the end part of the knife handle is provided with a screw hole and a knife groove, and the length of the knife handle is greater than the depth of the through hole to be processed;

the blade is fixed in the cutter groove of the cutter handle through a screw and comprises an upper cutting edge and a lower cutting edge, and the upper cutting edge and the lower cutting edge are intersected at one point and are distributed at 90 degrees.

When the through hole workpiece is chamfered, the first end of the through hole workpiece is machined by the upper cutting edge, then the cutter handle is operated to penetrate through the through hole, and chamfering of the second end of the through hole workpiece is achieved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
