Abstract
The utility model provides a kind of drilling tool, comprises working portion and mounting portion, it is characterized in that, described working portion is made up of drill bit, brill body, chamfering blades successively.Not only can improve machining accuracy, also shorten process time, ensure that the stability of product quality, save the time changed spent by cutter (high-speed steel drill becomes chamfer drill), whole efficiency promotes greatly.
Description
Technical field
The utility model belongs to cutting tool field, specifically a kind of boring bar tool.
Background technology
In prior art, the structure of various cutter is all made up of mounting portion and working portion, and the clamping part low-alloy steel of cutter is made, and working portion then forms two parts butt welding with high-speed steel.At present, the method being processed with the hole of chamfering is that employing one bores a through hole high-speed steel drill, then changes a chamfer drill, processes chamfering according to the program finished.But because process velocity is very fast, the cutter of high-speed steel drill easily weares and teares, and the chamfering that chamfer drill processes may depart from home position, and the center in its center and hole is inconsistent, causes defect ware more, follow-uply also need finishing of again doing over again.Such technique consumes a large amount of time and the muscle power of workman, and machining accuracy is low, and product quality also can not be guaranteed.
Utility model content
The technical problems to be solved in the utility model is to overcome the above-mentioned problems in the prior art point, provide a kind of drilling tool, not only machining accuracy can be improved, also shorten process time, ensure that the stability of product quality, save the time changed spent by cutter (high-speed steel drill becomes chamfer drill), whole efficiency promotes greatly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of drilling tool, comprises working portion and mounting portion, and described working portion is made up of drill bit, brill body, chamfering blades successively.
Preferably, body outer surface in obtuse angle, is bored in the shape of a spiral in described drill bit cross section.The drill bit at such obtuse angle is not easy fracture at high speeds, and spiral helicine brill body makes boring become to be more prone to.
Preferably, described mounting portion and working portion integration manufacture and form.After arranging like this, without the need to changing chamfer drill, the hole of band chamfering can be processed.
Preferably, described working portion is made by carbide alloy.The drill bit of carbide alloy is not easy to wear, and is not easy the breaking of rod under high drilling speed state, and avoid the operation of frequently changing brill that the breaking of rod causes, working (machining) efficiency gets a promotion.
Describe the lower method using the hole of above-mentioned tool sharpening band chamfering below, step is as follows:
S1, the clamping workpiece device of Digit Control Machine Tool installs workpiece to be processed 1;
S2, the cutter shaft of Digit Control Machine Tool installs described drilling tool, makes the drill bit of drilling tool towards the upper end of the preprocessing hole position of workpiece;
S3, starts described Digit Control Machine Tool, and drill bit starts highly to rotate, and the preprocessing hole position of cutter shaft downwardly towards workpiece from home position is moved;
S4, drilling tool starts processing along the preprocessing hole surface of position of workpiece, and after the working depth H preset to the feeding of Z movement in vertical direction, is retracted into described home position;
S5, stops drill bit rotational, process finishing.
When using cutter of the present utility model, chamfering can be processed together without the need to changing cutter, save the time changed spent by cutter (high-speed steel drill becomes chamfer drill), not only machining accuracy can be improved, also shorten process time, ensure that the stability of product quality, whole efficiency promotes greatly.

Wherein, description of reference numerals is as follows: 1: workpiece .1a: chamfering 1b: hole 2: drilling tool 2a: drill bit 2b: bore body 2c: chamfering blades 2d: mounting portion α: angle of drill bit H: default working depth.
Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As shown in Figure 1, a kind of drilling tool, comprises working portion and mounting portion 2d, and working portion is made up of drill bit 2a, brill body 2b, chamfering blades 2c successively, and the cross section α in obtuse angle of drill bit, bores body outer surface in the shape of a spiral.The drill bit at such obtuse angle is not easy fracture at high speeds, and spiral helicine brill body makes boring become to be more prone to.
Mounting portion and working portion integration manufacture and form.After arranging like this, without the need to changing chamfer drill, the hole of band chamfering can be processed.
Working portion is made by carbide alloy.The drill bit of carbide alloy is not easy to wear, and is not easy the breaking of rod under high drilling speed state, and avoid the operation of frequently changing brill that the breaking of rod causes, working (machining) efficiency gets a promotion.
Now need the hole processing band chamfering 1a on workpiece 1, lower mask body describes the lower method using the hole of above-mentioned tool sharpening band chamfering, and step is as follows:
S1, the clamping workpiece device of Digit Control Machine Tool installs workpiece to be processed 1;
S2, the cutter shaft of Digit Control Machine Tool installs described drilling tool, makes the drill bit of drilling tool towards the upper end of the preprocessing hole position of workpiece;
S3, starts described Digit Control Machine Tool, and drill bit starts highly to rotate, and the preprocessing hole position of cutter shaft downwardly towards workpiece from home position is moved;
S4, drilling tool starts processing along the preprocessing hole surface of position of workpiece, and after the working depth H preset to the feeding of Z movement in vertical direction, is retracted into described home position;
S5, stops drill bit rotational, process finishing.
While processing is portalled, chamfering 1a is also processed to form, so the center of hole and chamfering should be identical, avoids follow-up the doing over again that the defect ware that causes due to two center disunities causes.
When using cutter of the present utility model, chamfering can be processed together without the need to changing cutter, save the time changed spent by cutter (high-speed steel drill becomes chamfer drill), not only machining accuracy can be improved, also shorten process time, ensure that the stability of product quality, whole efficiency promotes greatly.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
