Abstract
The invention provides a kind of drilling tool, machining accuracy not only can be improved, process time is also shortened, it is ensured that the stability of product quality, the time spent by replacing cutter (high-speed steel drill is changed into chamfer drill) is saved, whole efficiency is greatly promoted.In addition, present invention also offers method using its processing chamfer hole.
Description
Technical field
The invention belongs to cutting tool field, specifically a kind of boring bar tool.
Background technology
In prior art, the structure of various cutters is all made up of mounting portion and working portion, and the clamping part of cutter is made with low-alloy steel, and working portion is then formed two parts butt welding with high-speed steel.At present, the method for being machined with the hole of chamfering is, using one, high-speed steel drill is bored a through hole, then changes a chamfer drill, processes chamfering according to the program that finishes.But as process velocity is very fast, the cutter of high-speed steel drill easily weares and teares, and the chamfering that chamfer drill is processed may deviate home position, and the center in its center and hole is inconsistent, causes defect ware more, subsequently also needs to finishing of doing over again again.Such technique takes a substantial amount of time the muscle power with workman, and machining accuracy is low, and product quality also cannot be guaranteed.
Content of the invention
The technical problem to be solved in the present invention is to overcome the above-mentioned problems in the prior art point, provide a kind of drilling tool, machining accuracy not only can be improved, process time is also shortened, ensure that the stability of product quality, the time spent by replacing cutter (high-speed steel drill is changed into chamfer drill) is saved, whole efficiency is greatly promoted.
For reaching above-mentioned purpose, the technical solution used in the present invention is：A kind of drilling tool, including working portion and mounting portion, the working portion is made up of drill bit, brill body, chamfering blades successively.
It is preferred that the drill bit section is in obtuse angle, body outer surface is bored in the shape of a spiral.The drill bit at so obtuse angle does not allow easy fracture at high speeds, and spiral helicine brill body causes drilling to become to be more prone to.
It is preferred that the mounting portion and working portion integration are fabricated by.After so arranging, chamfer drill need not be changed, you can process the hole with chamfering.
It is preferred that the working portion is made by hard alloy.The drill bit of hard alloy is not easy to wear, and under high drilling speed state be not easy the breaking of rod, it is to avoid frequently change the operation of brill caused by the breaking of rod, and working (machining) efficiency gets a promotion.
The lower method using hole of the above-mentioned tool sharpening with chamfering is set forth below, step is as follows：
S1, installs workpiece to be processed 1 on the clamping workpiece device of Digit Control Machine Tool；
S2, installs the drilling tool in the cutter shaft of Digit Control Machine Tool, makes the drill bit of drilling tool towards the upper end of the preprocessing hole position of workpiece；
S3, starts the Digit Control Machine Tool, and drill bit starts height and rotates, and cutter shaft starts to move to the preprocessing hole position of workpiece downwards from home position；
S4, drilling tool start to process along the preprocessing hole surface of position of workpiece, and feed after default working depth H to Z movement in vertical direction, are retracted into the home position；
S5, stops drill bit and rotates, process finishing.
In the cutter using the present invention, chamfering is processed together by cutter need not be changed, save the time spent by replacing cutter (high-speed steel drill is changed into chamfer drill), machining accuracy not only can be improved, process time is also shortened, ensure that the stability of product quality, whole efficiency are greatly promoted.

Specific embodiment
A preferred embodiment is named, and combines accompanying drawing to become apparent from the present invention is intactly described.
As shown in figure 1, a kind of drilling tool, including working portion and mounting portion 2d, working portion successively by drill bit 2a, bore body 2b, chamfering blades 2c and constitute, the section of drill bit α in obtuse angle bores body outer surface in the shape of a spiral.The drill bit at so obtuse angle does not allow easy fracture at high speeds, and spiral helicine brill body causes drilling to become to be more prone to.
Mounting portion and working portion integration are fabricated by.After so arranging, chamfer drill need not be changed, you can process the hole with chamfering.
Working portion is made by hard alloy.The drill bit of hard alloy is not easy to wear, and under high drilling speed state be not easy the breaking of rod, it is to avoid frequently change the operation of brill caused by the breaking of rod, and working (machining) efficiency gets a promotion.
Now need to process the hole with chamfering 1a on workpiece 1, the method for using hole of the above-mentioned tool sharpening with chamfering under lower mask body narration, step are as follows：
S1, installs workpiece to be processed 1 on the clamping workpiece device of Digit Control Machine Tool；
S2, installs the drilling tool in the cutter shaft of Digit Control Machine Tool, makes the drill bit of drilling tool towards the upper end of the preprocessing hole position of workpiece；
S3, starts the Digit Control Machine Tool, and drill bit starts height and rotates, and cutter shaft starts to move to the preprocessing hole position of workpiece downwards from home position；
S4, drilling tool start to process along the preprocessing hole surface of position of workpiece, and feed after default working depth H to Z movement in vertical direction, are retracted into the home position；
S5, stops drill bit and rotates, process finishing.
While portal, chamfering 1a also processes to be formed, so the center of hole and chamfering should be identical for processing, it is to avoid due to two center disunities, caused defect ware causes follow-up does over again.
In the cutter using the present invention, chamfering is processed together by cutter need not be changed, save the time spent by replacing cutter (high-speed steel drill is changed into chamfer drill), machining accuracy not only can be improved, process time is also shortened, ensure that the stability of product quality, whole efficiency are greatly promoted.
Although the foregoing describing the specific embodiment of the present invention, it will be appreciated by those of skill in the art that these are merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art on the premise of the principle and essence without departing substantially from the present invention can make various changes or modifications, but these changes and modification each fall within protection scope of the present invention to these embodiments.
