Abstract
The invention relates to a deep hole drill bit. The deep hole drill bit comprises a rod body and a head, wherein the rod body is a cylinder and is provided with a spiral part on which a chip removing channel is formed; a chip removing groove is formed on the head; a part of spherical body is formed on the top of the head; a notch is formed in the middle of the head; a replaceable blade is arranged in the notch and is platy; a strip is formed at the lower end of the blade to be inserted into the notch; and a triangular blade part is formed at the upper end of the blade. The deep hole drill bit has a simple structure and is convenient to operate and maintain; and after the deep hole drill bit is damaged, only the blade part is required to be replaced without the replacement of the whole drill bit, so that the cost is reduced.
Description
Technical field
The present invention relates to a kind of deep hole drill.
Background technology
Deep hole drill can be divided into welded type deep hole drill and machine usually and add the formula deep hole drill; The first plate of depth drill all is chip removal in adopting; And the blade of welded type deep hole drill cannot be changed, disposable use, and the blade that machine adds the formula deep hole drill can exchange; The cutter hub that machine adds the formula deep hole drill can forever use, and blade then can be changed.
It all is to adopt to award oily device and supply cooling fluid that welded type deep hole drill and machine add the formula deep hole drill, the process of interior chip removal, can be on solid materials such as carbon steel, steel alloy drilling deep hole; Draw ratio can reach 1: 100, existing deep hole drill, and structure is single; Easy abrasion; In case after the wearing and tearing then need change whole drill bit, cause cost to increase, difficult in maintenance.
For this reason, designer of the present invention is because above-mentioned defective through concentrating on studies and designing, comprehensively is engaged in for a long time the experience and the achievement of related industry for many years, and research and design goes out a kind of deep hole drill, to overcome above-mentioned defective.
Summary of the invention
The object of the present invention is to provide a kind of deep hole drill, it is simple in structure, and Operation and Maintenance is convenient, only needs to change blade part after damaging and gets final product, and whole drill bit need not to change, and has reduced cost.
For realizing above-mentioned purpose, the invention discloses a kind of deep hole drill, this deep hole drill comprises the body of rod and head, and the body of rod is a cylinder, has the spire that forms channel of chip removal on this body of rod; It is characterized in that:
Form chip area at head, the part spherosome is formed on the top of this head, forms fluting at the middle part of this head, is provided with removable blade in the fluting, and this blade is tabular, and the lower end forms strip to insert in the fluting, and the upper end forms the triangle blade.
Wherein: this spire comprises at least one helix, and this spire stretches out after extending to head vertically upward.
Wherein: these triangle blade both sides form cutting edge respectively.
Wherein: these two cutting edges 7 and 8 are not at same straight line and be parallel to each other.
Wherein: on this part spherosome, be formed with at least two grooves, at least two cutting pins are inserted in these two grooves at least.
Wherein: these two cutting pins are arranged in the both sides of this blade relatively along diameter.
Wherein: and two cutting pins are arranged with this blade bevel.
Wherein: these two the oblique bottoms from this part spherosome of cutting pin stretch out.
Through said structure, deep hole drill of the present invention has the following advantages:
1, simple in structure, dismounting is convenient;
2, easy to operate, change quick;
3, only need to change blade part and get final product, reduced cost, improved efficient.
The present invention will further describe in detail through following specific embodiment, and further combine will obtain knowing more and significantly understanding to the explanation of accompanying drawing.
Description of drawings
Fig. 1 has shown the front view of deep hole drill of the present invention.
Fig. 2 has shown the vertical view of deep hole drill of the present invention.
Fig. 3 has shown the cutaway view of Fig. 2 arrow part.
The specific embodiment
Referring to Fig. 1 to Fig. 3, shown the specific embodiment of deep hole drill of the present invention.
This deep hole drill comprises the body of rod 1 and head 2, and the body of rod 1 is a cylinder, has the spire 9 that forms channel of chip removal on this body of rod 1, and this spire 9 comprises at least one helix.
Stretch out vertically upward after this spire 9 extends to head 2, form chip area 6 and 10 at head thus, part spherosome 3 is formed on the top of this head 2; Wherein, form fluting, be provided with removable blade 4 in the fluting at the middle part of this head 2; This blade 4 is tabular, and the lower end forms strip to insert in the fluting, and the upper end forms the triangle blade; These triangle blade both sides form cutting edge 7 and 8 respectively, and preferably, these two cutting edges 7 and 8 are not at same straight line and be parallel to each other.
Wherein, on this part spherosome 3, be formed with at least two grooves, at least two cutting pins 5 are inserted in these two grooves at least, and these two cutting pins 5 are arranged in the both sides of this blade 4 relatively along diameter, and two cutting pins 5 are arranged with this blade 4 bevel a.
Referring to Fig. 3, the oblique bottom from this part spherosome 3 of these two cutting pins 5 stretches out.
Can know that through foregoing description blade of the present invention can arbitrarily be changed with the cutting pin, after wearing and tearing, can directly change, and has prolonged service life, has protected the body of rod and head.
It is obvious that, and above description and record only are for example rather than in order to limit disclosure of the present invention, application or use.Though described and be described in the drawings embodiment in an embodiment; But the optimal mode that the present invention does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present is with the specific examples of the instruction of embodiment of the present invention, and scope of the present invention will comprise any embodiment of the specification that falls into the front and appended claim.
