Abstract
The invention relates to a deep-hole drill bit, comprising a rod and a head, wherein the rod is of a cylinder and is provided with a spire for forming a chip removal passage; the head is a square column, the top of which is formed into a partial round sphere, an open groove is transversely formed in the middle of the partial round sphere along the diagonal line of the square column, and a replaceable blade is arranged in the open groove. The deep-hole drill bit disclosed by the invention has the advantages of simple structure and convenience for operation and maintenance, only a blade part needs to be changed after the deep-hole drill bit is damaged, and the whole drill bit does not need to be changed, such 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:
This head be square cylinder, part spherosome is formed on its top, forms fluting in the intermediate lateral of this part spherosome, this fluting is offered along the diagonal of this square cylinder, is provided with removable blade in the fluting.
Wherein: this blade is tabular, and the lower end forms strip to insert in the fluting, and the upper end forms the triangle blade, and these triangle blade both sides form cutting edge respectively.
Wherein: these two cutting edges are not at same straight line and be parallel to each other.
Wherein: the cutting edge of these triangle blade both sides forms the obtuse angle.
Wherein: form two grooves at this part spherosome respectively perpendicular to the both sides of this fluting, two auxiliary-blades are inserted in these two grooves.
Wherein: these two auxiliary-blades are arranged in the both sides of this blade relatively along diameter, and the bottom of two auxiliary-blades forms long strip-board shape and inserts in the said groove, and the oblique angle is formed on the top, and the both sides at top, oblique angle form front cutting edge.
Wherein: the front cutting edge of both sides is not at same straight line and be parallel to each other.
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.
The specific embodiment
Referring to Fig. 1 to Fig. 2, shown the specific embodiment of deep hole drill of the present invention.
This deep hole drill 1 comprises the body of rod 3 and head 2, and the body of rod 3 is a cylinder, has the spire that forms channel of chip removal on this body of rod 3, and this spire comprises at least one helix.
This spire ends after extending to head, this head 2 be square cylinder (referring to Fig. 2), part spherosome is formed on its top, wherein; Intermediate lateral at this part spherosome forms fluting, and this fluting is offered along the diagonal of this square cylinder, is provided with removable blade 4 in the fluting, and this blade 4 is tabular; Lower end formation highly is that the upper end formed triangle blade 5 in the strip of t1 was slotted with insertion, and the whole height of this blade 4 is h1; These triangle blade 5 both sides form cutting edge respectively, and preferably, these two cutting edges are not at same straight line and be parallel to each other; Preferably, the cutting edge of these triangle blade 5 both sides forms obtuse angle 11, and the angle at this obtuse angle 11 is γ.
Wherein, form two grooves at this part spherosome respectively perpendicular to the both sides of this fluting, two auxiliary-blades 7 and 8 are inserted in these two grooves; Thus, these two auxiliary-blades 7 and 8 are arranged in the both sides of this blade 4 relatively along diameter, and two auxiliary-blades 7 and 8 bottom form long strip-board shape and insert in the said groove; The oblique angle is formed on the top, and the both sides at top, oblique angle form front cutting edge, and the front cutting edge of both sides is not at same straight line and be parallel to each other; Intersect at a little 16 places, the height of auxiliary-blade is t2.
Preferably, the width d1 of this blade 4 equals the integral width d1 of two auxiliary-blades 7 and 8.
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.
