Abstract
The present invention relates to one kind lengthen twolip in row to cut depth drill, it by：Preceding cutting edge, cutter hub, side edge mouth, row cut hole, handle of a knife, handle of a knife set composition.Cutter hub and handle of a knife group are welded together, and cutter hub front end is provided with two preceding cutting edges to mistake, the side edge mouth for being axially arranged with three staggered cutting grooves of cutter hub, three rows is provided with side edge mouth and cut hole, handle of a knife set is cased with handle of a knife.The product structure is simple, reasonable in design, and it is to be processed into screw thread using the remaining portion of waste and old drill bit to be welded to form integral drill bit with handle of a knife set, it is not overall lengthening, axial cutting force can be mitigated significantly, processing is stable, precision is high, cutting effect is good, it is not easy to phenomena such as causing hole deflection, reduces percent defective, reduce production cost, drilling cuts hole provided with row, and row cuts easy and convenient, improves processing efficiency.
Description
Technical field：Row in twolip is lengthened the present invention relates to one kind and cuts depth drill, is related particularly to a kind of in processing tractor
Row cuts depth drill in the lengthening twolip used during gap bridge housing.
Background technology：At present, the machining equipment institutes such as the lathe that is used when processing tractor gap bridge housing, drilling machine, boring machine
Depth drill uses overall lengthening drill bit mostly, bears that axial cutting force is big, and processing is unstable, easily makes during drill bit length processing
Phenomena such as pore-forming deflection, machining accuracy being influenceed, percent defective is high, does not have row to cut hole on drill bit, and row cuts difficulty and cut, it is necessary to repeatedly arrange,
Processing efficiency is low.
The content of the invention：It is an object of the invention to overcome disadvantages mentioned above, there is provided and one kind lengthens row in twolip and cuts depth drill, it
The depth drill mainly solved used in the machining equipments such as the lathe used when processing tractor gap bridge housing, drilling machine, boring machine is big
Use overall lengthening drill bit more, bear that axial cutting force is big, and processing is unstable during drill bit length processing, it is existing to easily cause hole deflection etc.
As there is no row to cut hole on drill bit, row cuts difficult, it is necessary to the problems such as repeatedly row cuts.The object of the present invention is achieved like this, lengthens
In twolip row cut depth drill by：Preceding cutting edge, cutter hub, side edge mouth, row cut hole, handle of a knife, handle of a knife set composition.Cutter hub is welded in handle of a knife group
Together, cutter hub front end is provided with two preceding cutting edges to mistake, the side edge mouth for being axially arranged with three staggered cutting grooves of cutter hub, in side edge
Three rows are provided with mouthful and cut hole, and handle of a knife set is cased with handle of a knife.The product structure is simple, reasonable in design, and it is to utilize waste and old fried dough twist
The remaining portion of drill bit is processed into screw thread and is welded to form integral drill bit with handle of a knife set, is not overall lengthening, can mitigate axle significantly
To cutting force, processing is stable, and precision is high, and cutting effect is good, it is not easy to phenomena such as causing hole deflection, reduces percent defective, significantly
Reduce production cost, drilling cuts hole provided with row, and row cuts easy and convenient, improves processing efficiency, can improve 1-2 times.
Brief description of the drawings：
Accompanying drawing 1 is that the present invention lengthens the front view that row in twolip cuts depth drill.
Accompanying drawing 2 is that the present invention lengthens the side view that row in twolip cuts depth drill.
1-3-side edge of preceding 2-cutter hub of cutting edge mouth 4-row cuts hole
5-handle of a knife, 6-handle of a knife set
Embodiment：The most preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings, lengthen row in twolip and cut depth drill
By：Preceding cutting edge 1, cutter hub 2, side edge mouth 3, row cut hole 4, handle of a knife 5, the composition of handle of a knife set 6.5 groups of welded together, knives of cutter hub 2 and handle of a knife
The front end of body 2 is provided with two preceding cutting edges 1 to mistake, the side edge mouth 3 for being axially arranged with three staggered cutting grooves of cutter hub 2, in side edge mouth 3
On be provided with three rows and cut hole 4, handle of a knife set 6 is cased with handle of a knife 5.
During using processing, it is processed into screw thread using the remaining portion of waste and old spiral bit and is welded to form one with handle of a knife set
Body, it is not overall lengthening, cutwork is carried out by two preceding cutting edges 1 to mistake of drill bit, cutting effect is good, the iron filings of cutting
Hole 4 is cut by three rows on side edge mouth 3 to discharge, discharge is easy and convenient, due to being twice laid, reduces production cost.
