Abstract
The invention discloses a direct-insertion rapid-replacing drill. The direct-insertion rapid-replacing drill comprises a holder and a drill point. The holder is cylindrical and is coated with an abrasion-resistant layer. The abrasion-resistant layer is a ceramic layer. The holder is provided with a connecting bayonet which is triangular. A clamping gasket is arranged in the connecting bayonet and is a stainless steel gasket. A drill bushing is arranged behind the drill point. The drill point is of a circular-arc-shaped structure. Cutting edges are distributed on the drill point. The abrasion-resistant layer is arranged on the holder so that the abrasion resistance of the holder can be improved. The clamping gasket is arranged in the connecting bayonet so that the holder can be connected with a drilling machine more closely, the holder is prevented from shaking during using, the using effect of the drill cannot be influenced, and the machining quality of the drill is ensured. The drill bushing is arranged behind the drill point so that the drill point can be replaced conveniently without replacing the whole drill after the drill point is abraded, and the using cost of the drill is reduced.
Description
Technical field
The present invention relates to a kind of drill bit, be specifically related to a kind of direct insertion quick interchangeable drill bit.
Background technology
Drill bit effect in machining is extremely important, drill bit can be used to process cavernous structure parts, the use frequency of drill bit is higher, the replacing of drill bit is very fast, once bit damage need whole drill bit is replaced, add the cost of replacing, also improve drill bit simultaneously and use the maintenance cost of producer, a lot of drill bits are all adopt integrated formed structure at present, once damaging occurs in the apex point of drill bit, need all to replace drill bit, can not only change apex point, add maintenance cost, also has part drill bit when changing, easily wear away connecting hole at handle of a knife position, make to occur rocking when handle of a knife and drilling machine connection handle, have impact on the result of use of drill bit, it is impossible to ensure that the quality of boring.
Summary of the invention
It is an object of the invention to provide one to be completely embedded, the direct insertion quick interchangeable drill bit of one of simple in construction.
The technical scheme is that a kind of direct insertion quick interchangeable drill bit, including handle of a knife and apex point, described handle of a knife is cylindric, application head wearing layer on described handle of a knife, described wearing layer is ceramic layer, described handle of a knife is provided with connection bayonet socket, described connection bayonet socket is triangular shape, it is provided with clamping pad in described connection bayonet socket, described clamping pad is stainless steel gasket, is provided with drill bushing after described apex point, and described apex point is convex structure, on described apex point, distribution has cutting edge, the cutting angle of described cutting edge is 5 ��-8 ��.
The rear end of described apex point is provided with connector, and described connector is tapered structure, and described connector is provided with alignment pin, and described alignment pin is arranged below hole, location, described location Kong Weishen tapering pin-and-hole.
Described apex point is die cast, and described apex point is provided with bit-withdrawing slot, and described bit-withdrawing slot is semi arch structure, and described bit-withdrawing slot is coated with anti-adhesive linkage, and described anti-adhesive linkage is resin bed, and the thickness of described anti-adhesive linkage is 0.2cm-0.5cm.
The invention have the advantage that on handle of a knife, be provided with wearing layer, the anti-wear performance of handle of a knife can be mentioned, it is provided with clamping pad connecting in bayonet socket, when handle of a knife can be allowed to be connected with drilling machine more tight, will not be when in use, rocking occurs in handle of a knife, have impact on the result of use of drill bit, ensure that the crudy of drill bit, drill bushing it is provided with after apex point, the replacing of apex point can be facilitated, need not need to change whole drill bit after drill tip wear, save the use cost of drill bit, reduce the production cost using drill bit factory, apex point is provided with bit-withdrawing slot, quickly iron filings can be exited outside processing hole, improve working (machining) efficiency, ensure that completing in time of Fabrication Order.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1 is handle of a knife, 2 is apex point, and 3 is wearing layer, and 4 for connecting bayonet socket, and 5 is clamping pad, and 6 is drill bushing, and 7 is connector, and 8 is alignment pin, and 9 is bit-withdrawing slot.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
A kind of direct insertion quick interchangeable drill bit, including handle of a knife 1 and apex point 2, handle of a knife 1 is cylindric, application head wearing layer 3 on handle of a knife 1, wearing layer 3 is ceramic layer, handle of a knife 1 is provided with connection bayonet socket 4, connecting bayonet socket 4 is triangular shape, connect in bayonet socket 4 and be provided with clamping pad 5, clamping pad 5 is stainless steel gasket, drill bushing 6 it is provided with after apex point 2, apex point 1 is convex structure, on apex point 2, distribution has cutting edge, the cutting angle of cutting edge is 8 ��, the rear end of apex point 2 is provided with connector 7, connector 7 is tapered structure, connector 7 is provided with alignment pin 8, alignment pin 8 is arranged below hole, location, location Kong Weishen tapering pin-and-hole, apex point 2 is die cast, apex point 2 is provided with bit-withdrawing slot 9, bit-withdrawing slot 9 is semi arch structure, bit-withdrawing slot 9 is coated with anti-adhesive linkage, anti-adhesive linkage is resin bed, the thickness of anti-adhesive linkage is 0.5cm.
