Abstract

The utility model relates to a simplified multiple drill bit, comprising a connecting section, a drill bit body, and a pointed end. A cutter sleeve with two blades is sleeved on the drill bit body; a groove is positioned at the side of the drill bit body; the sections of the blades are in cylindrical or triangle shapes. The utility model has the advantages of batch production for shoulder holes as well as holes with chamfers, simple structure, convenient operation, low processing cost, wide scope of popularization and application.

Description

Simple and easy composite drill bit
(1) technical field
The utility model relates to the bit technique field, particularly a kind of simple in structure, easily manufactured, simple and easy composite drill bit in hole of processing shoulder hole and band chamfering in batch.
(2) background technology
The processing of the great various shoulder holes of quantity on various engineering goods, the especially large-scale workpiece must repeatedly be changed cutter processing or use the disposable processing of moulding compound tool.The frequent cutter of changing takies the long time of equipment, the corresponding increasing of labour intensity, and production efficiency is very low, causes the waste of resource.Use the composite drill bit of moulding, its cost is the twice of common drill bit, and the refacing property of drill bit is bad, and difficulty is big, and the part drill bit can't use after damaging.
(3) summary of the invention
The utility model is in order to overcome the deficiency of above technology, and a kind of simple in structure, easily manufactured, simple and easy composite drill bit in the hole of processing shoulder hole and band chamfering in batch is provided.
The utility model is realized by following measure: a kind of simple and easy composite drill bit, comprise drill bit linkage section, drill body and drill bit tip, and be set with the broach shell that has blade on the described drill body.
The further improvements of the utility model are: described blade is two.
For broach shell with firm being fixed on the drill bit of screw, there is a groove described drill body side.
The further improvements of the utility model are: described blade cross section is cylindricality or triangle.
The beneficial effects of the utility model:
In batch processing shoulder hole and the band chamfering the hole.
2. can reuse sharpening.
3. simple in structure, easy to operate, processing cost is low, suitable applying.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model processing shoulder hole.
Fig. 2 is the structural representation in the hole of the utility model processing belt chamfering.
1 drill bit linkage section among the figure, 2 broach shells, 3 screws, 4 blades, 5 drill bodies, 6 drill bit tips.
(5) specific embodiment
Embodiment 1
A kind of simple and easy composite drill bit as shown in Figure 1 comprises drill bit linkage section 1, drill body 5 and drill bit tip 6, and the broach shell 2 that has blade 4 is installed on the described drill body 5; Described blade is two, and the blade cross section is a cylindricality; There is a groove described drill body 5 sides, and described broach shell 2 is installed on the drill body 5 by screw 3, and screw 3 front ends are installed in the groove.
Embodiment 2
A kind of simple and easy composite drill bit as shown in Figure 2 comprises drill bit linkage section 1, drill body 5 and drill bit tip 6, and the broach shell 2 that has blade 4 is installed on the described drill body 5; Described blade is a slice or two, and the blade cross section is a triangle; There is a groove described drill body 5 sides, and described broach shell 2 is installed on the drill body 5 by screw 3, and screw 3 front ends are installed in the groove.
