Abstract
A combined drill bit comprises a tool shank and a drill bit between which a tool holder is arranged, wherein a hard alloy blade is arranged on the tool holder; a chamfer cutting edge is arranged at the root parts of both the hard alloy blade and the drill bit; a cutting edge is arranged on the edge of the hard alloy blade, which is perpendicular to the drill bit; and a slugslot is formed on the tool holder and arranged on one side of the hard alloy blade. The combined drill integrates drilling, plane facing and chamfering into one procedure to greatly simplify the processing procedure, and has the advantages of quickness in processing and high precision and greatly improved processing efficiency.
Description
Technical field
The utility model belongs to Machining Technology, the moulding drill bit of especially a kind of disposable processing boring, spot facing, chamfering.
Background technology
Quite a few procedures are all wanted in general workpiece processing boring, all are that operation break-down carries out like boring, spot facing and chamfering.The cutter that different operations needs all is different, in the circulation of different operations, can influence machining accuracy, and working (machining) efficiency is low.
The utility model content
The objective of the invention is to overcome above-mentioned deficiency, a kind of composite drill bit is provided, be combined into an operation to boring, spot facing and chamfering three each operations, thereby improve part precision and work efficiency of workers.
The technical scheme that technical problem adopted that the utility model solves is:
A kind of composite drill bit comprises handle of a knife and drill bit, it is characterized in that being provided with knife rest between handle of a knife and drill bit, and knife rest is provided with carbide chip, and the root place of carbide chip and drill bit is provided with the chamfering cutting edge, and the edge of the vertical drill bit of carbide chip is provided with cutting edge.Drill bit is boring, and the chamfering cutting edge is that chamfering is used, and cutting edge is that spot facing is used.
During use, be installed in the handle of a knife of composite drill bit on the drilling machine, workpiece is placed on the rig floor; Realize that drill bit is to Workpiece boring; The chamfering cutting edge of carbide chip carries out chamfering to the interior edge in hole, and when the last plane of workpiece contacts with the cutting edge place, cutting edge carries out spot facing to workpiece.The utility model while, realization boring, spot facing and chamfering are accomplished in one procedure.Thereby manufacturing procedure greatly simplifies, processing rapidly, reliable in quality, working (machining) efficiency improves greatly, and the utility model simple in structure, be easy to make.
During practical implementation, knife rest is provided with flute, and flute is located at carbide chip one side.Flute is to guarantee when boring, spot facing and chamfering, can successfully get rid of bits bar, the bits powder etc. of workpiece.
The beneficial effect of the utility model is: the boring of the utility model collection, spot facing and chamfering are one procedure, and manufacturing procedure is greatly simplified, and processing is rapid, and precision is high, and working (machining) efficiency improves greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment carbide chip.
Among the figure: 1, handle of a knife 2, knife rest 3, carbide chip 4, drill bit 5, flute 31, chamfering cutting edge 32, cutting edge.
The specific embodiment
In Fig. 1 and Fig. 2, a kind of composite drill bit comprises handle of a knife 1 and drill bit 4; 4 on handle of a knife 1 and drill bit are provided with knife rest 2; Be welded with carbide chip 3 on the knife rest 3, carbide chip 3 is provided with chamfering cutting edge 31 with the root place of drill bit 4, and the edge of carbide chip 3 vertical drill bits 4 is provided with cutting edge 32; Knife rest 2 is provided with flute 5, and flute 5 is located at carbide chip 3 one sides.Drill bit 4 is boring, and chamfering cutting edge 31 is used for chamfering, and cutting edge 32 is used for spot facing, and flute 5 is to guarantee when boring, spot facing and chamfering, can successfully get rid of bits bar, the bits powder etc. of workpiece.
During use, be installed in the handle of a knife 1 of composite drill bit on the drilling machine, workpiece is placed on the rig floor; Realize that drill bit 4 is to Workpiece boring; Chamfering is carried out on the interior edge in 31 pairs of holes of chamfering cutting edge of carbide chip, and when the last plane of workpiece contacts with cutting edge 32 places, 32 pairs of workpiece of cutting edge carry out spot facing.The utility model while, realization boring, spot facing and chamfering are accomplished in one procedure.Thereby manufacturing procedure greatly simplifies, processing rapidly, reliable in quality, working (machining) efficiency improves greatly, and the utility model simple in structure, be easy to make.
At last, it is also to be noted that what more than enumerate only is the specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive from the disclosed content of the utility model or associate all should be thought the protection domain of the utility model.
