Abstract
The utility model relates to a sawtooth type electrical boring driller, which comprises a locating drill stem, a cutter body, a rotating shaft and a spring sleeved on a center drill stem. The locating drill stem is firmly fixed on the rotating shaft by a bolt, the opening end of the cutter body is evenly welded and inlaid with a plurality of alloy cutting edges, the cutting edges of the alloy cutting edges are ground with sawtooth type tooth tops, and the front part of the alloy cutting edges welded on the cutter body is provided with a scrap discharging groove. The sawtooth type electrical boring driller has long service life and smooth boring, the drilled hole is round and smooth and has good smooth finish, the boring speed is quick, the sawtooth type electrical boring driller is applicable to an iron plate, a copper plate, an aluminum plate, a bakelite plate, etc., and can be matched with a gun driller or a drill press to use.
Description
Technical field
The utility model relates to a kind of drilling tool, refers in particular to a kind of electronic super hole cutter.
Background technology
Drilling machine or common electric drill, the aperture that is got out when boring are limited by the size of drill bit, and can not bore macropore, and it is also powerless to bore macropore, and hopes thing heave a sigh.In order to get out bigger specification and round hole, more common electronic hole making drill is made up of body centre drill and the spring that is enclosed within on the drilling rod of center, and the front end of body is embedded with drill bit.When this hole making drill is studied intensively the hole, at first go out an aperture with the centre drill bar drill after, utilize center drilling rod location, rely on body front end drill bit that the hole is left then.The part but it comes with some shortcomings is worn and torn easily as the drill bit on the body, and it is not steady to hole, and scrap is difficult for discharging in the perforate process, and the hole that gets out is not slick and sly, fineness is poor, and penetration rate waits extremely slowly.
The utility model content
The purpose of this utility model is prior art is improved, and provides a kind of sawtooth pattern electronic super hole cutter, long service life, and boring is steady, and the hole circle that gets out is sliding, fineness good, and penetration rate is fast.
For achieving the above object, the solution that the utility model is taked is: the electronic super hole cutter of a kind of sawtooth pattern, it is made of the spring of locating drilling rod, cutter hub, rotating shaft and be enclosed within on the drilling rod of center, to locate drilling rod with screw is fastened in the rotating shaft, the cutter hub openend welds equably and studs with some alloy cutting edges, the edge mill of alloy cutting edge has the sawtooth pattern crown, and has chip area at the place, forward position of cutter hub welding alloy cutting edge.
The utility model scrap is easily arranged, and the alloy cutting edge is more not easy to wear, has improved service life owing to have chip area at the place, forward position of cutter hub welding alloy cutting edge; Because the cutter hub openend welds equably and studs with some alloy cutting edges, the hole is steady, and the hole circle that gets out is sliding, fineness good, and penetration rate is fast.
Description of drawings
Fig. 1 is the structural representation of present embodiment.
Fig. 2 sawtooth pattern crown shape figure.
Among the figure: 1, rotating shaft, 2, screw, 3, cutter hub, 4, the alloy cutting edge, 5, spring, 6, the location drilling rod, 7, chip area.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, the electronic super hole cutter of a kind of sawtooth pattern, it is made of the spring 5 of locating drilling rod 6, cutter hub 3, rotating shaft 1 and be enclosed within on the center drilling rod 6, to locate drilling rod 6 with screw 2 is fastened in the rotating shaft 1, cutter hub 3 openends weld equably and stud with some alloy cutting edges 4, the edge mill of alloy cutting edge 4 has the sawtooth pattern crown, and has chip area 7 at the place, forward position of cutter hub 3 welding alloy cutting edges 4.
Referring to Fig. 1, spring 5 is taper, and collar extension is flat thick, interior young close-fitting.It is enclosed within location drilling rod 6, has improved the smooth operation degree, bores the effect of back owing to spring, and the circle that gets out is withdrawed from can come off automatically.
Referring to Fig. 1 and Fig. 2, the sawtooth pattern crown has A, B, three kinds of difformities of C, and combination collocation has improved drilling speed.
Referring to Fig. 1, cutter hub 3 and rotating shaft 1 are integral, and have improved bulk strength.
Present embodiment has been given full play to the effect of sawtooth pattern crown alloy cutting edge 4, improved service life, than the long service life of common alloy hole making drill more than 3 times, improved the perforate degree of depth, than dark 3 times of common alloy hole making drill perforate, be applicable to iron plate, copper coin, aluminium sheet and bakelite plate etc., with power drill or the supporting use of drilling machine.
