Abstract
The utility model relates to the technical field of drill bits, in particular to a drill bit capable of chamfering. The drill bit comprises a connecting part and a drilling part, wherein the drilling part is provided with a chamfering device for chamfering; the chamfering device is a compound chamfering tool; a mounting hole matched with the aperture of the drilling part is formed at the top of the compound chamfering tool; a chamfering blade is formed at the bottom of the compound chamfering tool; and the chamfering device is provided with a screw hole for fixing the chamfering device at the drilling part, so that the chamfering device is fixed at the drilling part through an adjusting screw which is used for adjusting the height of the chamfering device fixed at the drilling part. When the drill bit is in use, the chamfering device chamfer a hole site while the drilling part drills, and additional chamfering is not required, so that the drill bit is convenient to operate and high in working efficiency when drilling the hole site to be chamfered.
Description
Technical field
The utility model relates to the bit technique field, but relates in particular to a kind of drill bit of chamfering.
Background technology
In the process of industrial processes, machine-building, a lot of workpiece need to be holed.Wherein, some workpiece also will carry out chamfering at the opening part of position, hole except will holing.For this position, hole that needs chamfering, traditional method is, first holes by drill bit, then carries out chamfering by other facing attachment, and inconvenient operation, operating efficiency are not high.
The utility model content
But the purpose of this utility model is to provide for the deficiencies in the prior art a kind of drill bit of chamfering of easy to operate, high efficiency.
To achieve these goals, but the utility model provides a kind of drill bit of chamfering, includes connecting portion, bore portion, and described bore portion is equipped with the facing attachment for chamfering;
Described facing attachment is chamfering compound cutter, and the top of described chamfering compound cutter offers the installing hole that mates with the aperture of described bore portion, and the bottom of described chamfering compound cutter forms chamfered cutting edge;
Described facing attachment offers the screw for fixing to described bore portion, makes described facing attachment be fixed in described bore portion by set screw, is fixed in the height of bore portion to regulate facing attachment.
Preferably, described bore portion is threaded bore section.
The utility model beneficial effect is: the utility model includes connecting portion, bore portion, described bore portion is equipped with the facing attachment for chamfering, the utility model in use, when can hole by bore portion, by facing attachment, chamfering is carried out in the position, hole, need not to carry out in addition again chamfering, therefore, the utility model is holed to the position, hole that needs chamfering, easy to operate, high efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of chamfering compound cutter of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Please refer to Fig. 1 and Fig. 2, but the drill bit of chamfering of the present utility model includes connecting portion 1, bore portion 2, connecting portion 1 is used for connecting driving mechanism, and bore portion 2 is used for workpiece is holed; Wherein, bore portion 2 is equipped with the facing attachment for chamfering, and facing attachment can carry out chamfering to the opening of the position, hole of boring.
Specifically, facing attachment is chamfering compound cutter 3, and the top of chamfering compound cutter 3 offers the installing hole 4 that mates with the aperture of bore portion 2, makes chamfering compound cutter 3 be sheathed on bore portion 2 by installing hole 4; The bottom of chamfering compound cutter 3 forms chamfered cutting edge 5, makes chamfering compound cutter 3 carry out chamfering by 5 pairs of openings that bore position, hole well of chamfered cutting edge.
Wherein, facing attachment offers the screw 6 for fixing to bore portion 2, make facing attachment be fixed in bore portion 2 by set screw, in use, the user is by unscrewing the set screw in screw 6, can regulate the height that facing attachment is fixed in bore portion 2, so that for the boring of the position, hole of different depth; Tighten again the set screw in screw 6, fixedly facing attachment.
Wherein, bore portion 2 is threaded bore section, and certainly, according to reality boring needs, described bore portion 2 also can be the bore portion of other type, and is not limited only to the threaded bore section that the present embodiment is selected.
In sum, the utility model in use, when can hole by bore portion 2, chamfering is carried out in the position, hole that 5 pairs of bore portion 2 of chamfered cutting edge by chamfering compound cutter 3 get out, need not to carry out in addition again chamfering, therefore, the utility model is holed to the position, hole that needs chamfering, and operation is for convenience of, high efficiency.
Should be noted that at last; above embodiment is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; although with reference to preferred embodiment, the utility model has been done to explain; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or is equal to replacement, all belong to protection domain of the present utility model.
