Abstract
The utility model discloses a kind of anti-sticking bits depth drill and deep hole pilot drill, it is related to machine tool field, there is provided a kind of chip removal smoothly depth drill.Depth drill includes drill main body and the pilot drill positioned at drill main body center；Drill main body includes the sword valve on the outside of pilot drill, and centering drilling and limbers are provided with drill main body；Pilot drill loads centering drilling, and effluent trough is provided with pilot drill, and effluent trough and the hole wall of centering drilling are collectively forming apopore, and apopore connects with limbers；Be provided with horizontal chip area on pilot drill in effluent trough both sides, horizontal chip area be located at immediately ahead of apopore and with sword valve face.Above-mentioned pilot drill also can be separately as a product.The horizontal chip area with sword valve face is provided with effluent trough both sides on pilot drill, so as to eliminate the angle of wedge between pilot drill and sword valve so that chip not by the condition of clamping stagnation, easily by.Horizontal chip area is located at immediately ahead of apopore, and cooling water can wash away chip.
Description
Technical field
It the utility model is related to machine tool field, more particularly to a kind of anti-sticking bits depth drill and deep hole pilot drill
Background technology
A kind of depth drill as shown in Figure 1 to Figure 3, including drill main body and the pilot drill positioned at drill main body center, centering
Boring from the front loaded drill main body of drill main body, drill main body includes the sword valve on the outside of pilot drill.In order to supply coolant,
Limbers is additionally provided with drill main body, the edge of pilot drill is provided with water-flowing trough, and coolant is supplied by limbers, and from water flowing
Groove outflow cooling drill bit simultaneously helps its chip removal.
The gap at a between above-mentioned deep hole pilot drill water-flowing trough and sword valve in i.e. Fig. 2 is smaller, forms the angle of wedge, part iron
Bits can be influenceed to be washed into the angle of wedge by coolant reaction force so that iron filings easily by clamping stagnation, enter so as to hinder other iron filings
Enter in cutter hub chip pocket, result in that pilot drill chip removal is not smooth and to collapse pilot drill scarce.
Utility model content
The technical problems to be solved in the utility model is：A kind of depth drill that can prevent card from considering to be worth doing is provided.
Technical scheme for the use that solves the above problems is：Depth drill includes drill main body and positioned at drill main body center
Pilot drill；Drill main body includes the sword valve on the outside of pilot drill, and centering drilling and limbers are provided with drill main body；Centering
Bore and load centering drilling, water-flowing trough is provided with pilot drill, water-flowing trough and the hole wall of centering drilling are collectively forming apopore, water outlet
Hole connects with limbers；Horizontal chip area is provided with pilot drill in water-flowing trough both sides, before horizontal chip area is located at apopore just
Side and with sword valve face.
Another technical problem to be solved in the utility model is：A kind of centering for depth drill beneficial to chip removal is provided
Bore.
Technical scheme for the use that solves the above problems is：Water-flowing trough is provided with pilot drill, in water-flowing trough on pilot drill
Both sides are provided with horizontal chip area.
The beneficial effects of the utility model are：The horizontal chip removal with sword valve face is provided with water-flowing trough both sides on pilot drill
Groove, so as to eliminate the angle of wedge between pilot drill water-flowing trough and sword valve so that iron filings are not by the condition of clamping stagnation.Horizontal chip area position
Immediately ahead of apopore, cooling water can wash away chip.Therefore the utility model effectively improves the situation of iron filings clamping stagnation, improves
The service life of depth drill.

Embodiment
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
In order to provide a kind of depth drill that can prevent card from considering to be worth doing, as shown in Figure 5 and Figure 6：Depth drill includes the He of drill main body 1
Pilot drill 4 positioned at the center of drill main body 1；Drill main body 1 includes the sword valve 2 positioned at the outside of pilot drill 4, is set in drill main body 1
It is equipped with centering drilling and limbers；Pilot drill 4 loads centering drilling, and water-flowing trough 5, water-flowing trough 5 and centering are provided with pilot drill 4
The hole wall of drilling is collectively forming apopore, and apopore connects with limbers；The both sides of water-flowing trough 5 are provided with transverse direction on pilot drill 4
Chip area 6, horizontal chip area 6 be located at immediately ahead of apopore and with the face of sword valve 2.
The both sides of water-flowing trough 5 are provided with the horizontal chip area 6 with the face of sword valve 2 on pilot drill 4, so as to eliminate pilot drill
The angle of wedge between 4 and sword valve 2 so that chip easily by.The horizontal groove of chip removal 6 is located at immediately ahead of apopore, and cooling water can be washed away and cut
Bits.Therefore the utility model effectively improves the situation of iron filings clamping stagnation, improves the service life of depth drill.
Above-mentioned pilot drill 4 also can be separately as a product, and it is as shown in fig. 6, be provided with water-flowing trough 5, calmly on pilot drill 4
The heart bores and the both sides of water-flowing trough 5 is provided with horizontal chip area 6 on 4.The mounting structure of pilot drill 4 should ensure that it loads drill main body 1
Afterwards, horizontal chip area 6 be located at immediately ahead of apopore and with the face of sword valve 2.
