Description
Technical field
The utility model relates to a kind of drill bit, is specifically related to a kind of direct insertion quick interchangeable drill bit.
Background technology
The effect of drill bit in machining is extremely important, drill bit can be used for processing poroid structural elements, the frequency of utilization of drill bit is higher, the replacing of drill bit is very fast, once bit damage need whole drill bit is changed, add the cost of replacing, also improve the maintenance cost that drill bit uses producer simultaneously, a lot of drill bit is all adopt integrated formed structure at present, once damaging appears in the apex point of drill bit, drill bit is needed all to replace, only can not change apex point, add maintenance cost, also has part drill bit when replacing, 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, the quality of holing can not be ensured.
Summary of the invention
The purpose of this utility model is to provide a kind of connection closely, the simple a kind of direct insertion quick interchangeable drill bit of structure.
The technical solution of the utility model is: a kind of direct insertion quick interchangeable drill bit, comprise 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, clamping pad is provided with 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, described apex point is distributed with cutting edge, and 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 for there being tapered configuration, and described connector is provided with alignment pin, is provided with locating hole below described alignment pin, and described locating hole is dark 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 utility model has the advantages that: on handle of a knife, be provided with wearing layer, the anti-wear performance of handle of a knife can be mentioned, clamping pad is provided with in connection bayonet socket, it is more tight when handle of a knife can be allowed to be connected with drilling machine, can not be when in use, rocking appears in handle of a knife, have impact on the result of use of drill bit, ensure that the crudy of drill bit, drill bushing is provided with after apex point, the replacing of apex point can be facilitated, need after not needing drill tip wear to change whole drill bit, save the use cost of drill bit, reduce the production cost using drill bit factory, apex point is provided with bit-withdrawing slot, can fast iron filings be exited outside machining hole, improve working (machining) efficiency, ensure that completing in time of Fabrication Order.
