Abstract

The utility model belongs to tooling layout technology, and relates to a cut-off tool capable of finishing chamfering simultaneously. The cut-off tool comprises a tool holder (1) and a cut-off tool bit (2), wherein the section of the tool holder (1) is square. The cut-off tool is characterized in that the two sides of the root portion of the cut-off tool bit (2) is connected with the front end of the tool holder (1) through a chamfering cutter (3), a blade of the chamfering cutter (3) is of a circular-arc shape or a straight line shape, and the circular-arc shape or the straight line shape is identical with chamfering of parts to be machined. The cut-off tool can be used for finishing cutting off and chamfering machining of shaft parts simultaneously, machining time is shortened, and production efficiency is improved.

Description

A kind of cutoff tool of finishing chamfering simultaneously
Technical field
The utility model belongs to the Tool Design technology, relates to a kind of cutoff tool that can finish axial workpiece cut-out and chamfering simultaneously.
Background technology
The existing axial workpiece that has chamfering needs cut-out and chamfering two procedures just can finish in cutting-off process, has prolonged machining period, has reduced production efficiency.
Summary of the invention
The purpose of this utility model is: a kind of cutoff tool that can finish axial workpiece cut-out and chamfering simultaneously is provided, to shorten machining period, enhances productivity.
The technical solution of the utility model is: a kind of cutoff tool of finishing chamfering simultaneously, comprise that the cross section is foursquare handle of a knife 1 and cutting-blade head 2, it is characterized in that, be connected by chamfering cutting knife 3 between the root both sides of cutting-blade head 2 and the front end of handle of a knife 1, the blade of chamfering cutting knife 3 is circular arc or linear, this circular arc or linear are consistent with the chamfering of part to be processed, the anterior angle α of chamfering cutting knife 3=6 °~12 °, measure-alike and the position of the chamfering cutting knife 3 of cutting-blade head 2 both sides is symmetrical, equals the radius of part to be processed to the distance h of both sides chamfering cutting knife 3 mid point A lines from the front end of cutting-blade head 2.
The utility model has the advantages that: can finish cut-out and the chamfer machining of axial workpiece simultaneously, shorten machining period, improve production efficiency.Evidence, when processing the axial workpiece of using on certain type aircraft, working (machining) efficiency ratio of the present utility model operation raising in two steps originally is more than 2 times.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below the utility model is described in further details.Referring to Fig. 1, a kind of cutoff tool of finishing chamfering simultaneously, comprise that the cross section is foursquare handle of a knife 1 and cutting-blade head 2, it is characterized in that, be connected by chamfering cutting knife 3 between the root both sides of cutting-blade head 2 and the front end of handle of a knife 1, the blade of chamfering cutting knife 3 is circular arc or linear, this circular arc or linear are consistent with the chamfering of part to be processed, the anterior angle α of chamfering cutting knife 3=6 °~12 °, measure-alike and the position of the chamfering cutting knife 3 of cutting-blade head 2 both sides is symmetrical, equals the radius of part to be processed to the distance h of both sides chamfering cutting knife 3 mid point A lines from the front end of cutting-blade head 2.
Using method of the present utility model is: the two ends of processed axial workpiece are clamped with three-jaw chuck, when being cut branch, processed axial workpiece has no progeny, continue feed, because the blade of chamfering cutting knife 3 is consistent with the chamfering of part to be processed, therefore after part to be processed is cut, can continue to finish the processing of chamfering, save process time, improve operating efficiency.
Embodiment 1
Processed axis part diameter is of a size of φ 12mm, and chamfer dimesion is R3, selects anterior angle α=6 ° of chamfering cutting knife 3, and the circular arc of chamfering cutting knife 3 is of a size of R3, the distance h=6mm from the front end of cutting-blade head 2 to both sides chamfering cutting knife 3 mid point A lines.
Embodiment 2
Processed axis part diameter is of a size of φ 16mm, and chamfer dimesion is 4x60 °, selects anterior angle α=10 ° of chamfering cutting knife 3, and the linear of chamfering cutting knife 3 is of a size of 4x60 °, the distance h=8mm from the front end of cutting-blade head 2 to both sides chamfering cutting knife 3 mid point A lines.
