Abstract
The utility model relates to a flat wind drill, in particular to a high-strength flat wing drill which mainly solves the technical problems that a flat wing drill in the prior art is complex in structure, high in production cost, poor in strength, short in service life and the like. The high-strength flat wing drill comprises a drill stem main body (1) and is characterized in that one end of the drill stem main body (1) is connected with a drill head (3) through a first connection rod (2), a tip (4) is arranged at the outer end of the drill head, the other end of the drill stem main body is connected with an end socket (6) through a second connection rod (5), and a location groove (7) is arranged between the end socket and the second connection rod.
Description
Technical field
The utility model relates to a kind of flat-wing driller, especially relates to a kind of high strength flat-wing driller.
Background technology
Used woodworking flat drill is comprised of apex point, circumference cutting edge, main cutting edge, flute, drilling rod, drillstock at present, apex point places the center of drilling rod front end face, the cylindrical place of drilling rod front end face is equipped with the circumference cutting edge, the centre of drilling rod front end face, the both sides of apex point are equipped with respectively two main cutting edges, the front of main cutting edge is flute, and drillstock places the rear end of drilling rod.Chinese patent discloses a kind of knife changable self tapping woodworking flat drill (Granted publication number: CN201147954), it comprises drill body, apex point, drilling rod and drillstock, drill body, drilling rod and drillstock are made as one, be provided with threaded apex point in the drill body front end deep hole, the drill body front end is provided with a skewed slot, is provided with dismountable blade in skewed slot, fix by screw, apex point is provided with oblique shoulder, is pressed on the blade; Blade is comprised of main cutting edge and circumference cutting edge, and the circumference cutting edge is located at the termination of main cutting edge, and the main cutting edge front is provided with flute; Drilling rod is provided with horizontal screw, connects with drill body front end deep hole, and screw is located in the screw.But the structure of this flat-wing driller is comparatively complicated, and production cost is higher, and intensity is relatively poor, and service life is shorter.
The utility model content
The utility model provides a kind of high strength flat-wing driller, and it mainly is that to solve the structure of the existing flat-wing driller of prior art comparatively complicated, and production cost is higher, and intensity is relatively poor, the technical problem that service life is short etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of high strength flat-wing driller of the present utility model, comprise the drilling rod body, an end of described drilling rod body is connected with drill bit by head rod, and the drill bit outer end is provided with top, the drilling rod body other end is connected with the termination by the second connecting rod, is provided with locating slot between termination and the second connecting rod.Drilling rod body, head rod, the second connecting rod, drill bit, termination all are that integral body is made, and intensity is higher.Top taper angle can be 60o.The diameter of drilling rod body is greater than the diameter of head rod, the second connecting rod.Can by the locating slot between termination and the second connecting rod, whole flat-wing driller be fixed on the rig.
As preferably, between described head rod and the drill bit, all be provided with the transition conical surface between drilling rod body and the second connecting rod.By the transition conical surface can strengthen between head rod and the drill bit, bonding strength between drilling rod body and the second connecting rod.
As preferably, outer end, described termination is provided with chamfering, can easily flat-wing driller be encased in the equipment.
Therefore, structure of the present utility model is comparatively simple, and production cost is lower, and intensity is higher, and service life is longer.
