Abstract
The utility model discloses a multifunctional drilling tool which comprises a drill handle, a drill body, a drill bit, a drill back, and a chip space, which is characterized in that an elastic bidirectional chamfering device is arranged on the drill back. The utility model has the advantages that drilling holes, and bidirectional chamfering or drilling holes, and bidirectional chamfering, and milling the whole into surface can be finished at the same time in one working cycle from feeding drill to retracting knife.
Description
The invention belongs to turning, boring technical field.
In the prior art, the processing metal workpiece is made up of drillstock, drill body and drill bit etc. as the drilling tool of boring.The back of the body of boring and chip area are arranged on the drill body.Drill bit is positioned at the drill body front end.The shortcoming of such drilling tool is only to supply the usefulness of boring.1987, portion of China Metallurgical Industry Panzhihua Iron was introduced the HCB1000/3S saw from West Germany WAGNER company and has been bored bastard machine tool, and its drilling tool has the function of boring and unidirectional chamfering.Therefore, there is following weak point in this drilling tool:
1. advancing brill-withdrawing in work period, can not finish boring-simultaneously the operation of the hole two-port chamfering of being bored;
2. self can not control the chamfering degree of depth.
One of purpose of the present invention is, proposed a kind ofly advancing brill-withdrawing in work period, finishes simultaneously that boring-to the drilling tool of the hole two-port chamfering of being bored, its chamfering degree of depth is controlled by drilling tool self.
Another object of the present invention is, proposed a kind ofly advancing brill-withdrawing in work period, finishes simultaneously that boring-to the drilling tool of the hole two-port chamfering-whole institute of mill machined surface of being bored, its chamfering degree of depth is controlled by drilling tool itself.
To achieve these goals, the present invention proposes following solution:
This drilling tool comprises drillstock, drill body and drill bit etc.The back of the body of boring and chip area are arranged on the drill body.Drill bit is positioned at the drill body front end.Bore back the two-way facing attachment of one elasticity is arranged.Feature is further, and the two-way facing attachment of elasticity is made up of groove, boss, elasticity lattice framing, two-way chamfering tool and screw etc.Groove is positioned at the brill back.Boss is positioned at any end of groove.Elasticity lattice framing one termination has two-way chamfering tool, and its other end is fixed on the boss by screw.
This drilling tool not only comprises the two-way facing attachment of the elasticity of above-mentioned drilling tool, but also comprises an elasticity mill engagement positions of boring back at least therein.Its further feature be that elasticity mill engagement positions is made up of groove, boss, elasticity lattice framing, grinding tool and screw etc.Groove is positioned at the brill back.Boss is positioned at any end of groove.Elasticity lattice framing one termination has grinding tool, and its other end is fixed on the boss by screw.The forward and backward working face of grinding tool lags behind the forward and backward working face of the two-way facing attachment cutter of corresponding elasticity respectively.
Adopt drilling tool of the present invention, have following advantage:
1. advancing brill-withdrawing in work period, can finish boring-simultaneously the operation of the hole two-port chamfering of being bored;
2. advancing brill-withdrawing in work period, can finish boring-simultaneously the operation of the hole two-port chamfering-whole institute of mill machined surface of being bored;
3. the chamfering degree of depth is controlled by drilling tool self;
4. improve operating efficiency, saved the working time;
5. improve the fineness of machined surface, guaranteed chamfer quality.

Fig. 3 (b) is the C-C cutaway view of Fig. 3 (a).
Below, in conjunction with the accompanying drawings inventive concept is further described.
Embodiment 1
As Fig. 1 (a) with (b).This drilling tool comprises drillstock 1, drill body 2 and drill bit 7 etc.The back of the body of boring 9 and chip area 8 are arranged on the drill body.Drill bit 7 is positioned at drill body 2 front ends.Bore on the back of the body 9 the two-way facing attachment of an elasticity is arranged.This device is made up of groove 10, boss 3, elasticity lattice framing 5, two-way chamfering tool 6 and screw 4 etc.Groove 10 is positioned at and bores on the back of the body 9.Boss 3 is positioned at groove 10 (also being located at the outer end).One termination of elasticity lattice framing 5 has two chamfering tools 6, and its other end is fixed on the boss 3 by screw 4.
During work, drilling tool does to revolve motion with respect to workpiece and drilling operating is carried out in feed motion.When drilling tool pierced certain depth, the two-way facing attachment of elasticity was started working, and the front edge of promptly two-way chamfering tool 6 begins to carry out chamfering.When chamfering arrives certain depth, the radial cutting force effect that two-way chamfering tool 6 produces when being subjected to the effect of centripetal force and chamfering cutting, and when increasing to certain value, make after elasticity lattice framing 5 is forced to be pressed in the groove 10, along with continuing feeding, after the sword inclined-plane that retreads of the saturating and two-way chamfering tool 6 of hole drill passes the hole, because of the elastic restoring force effect of elasticity lattice framing 5 makes two-way chamfering tool 6 reset.After this, enter withdrawing-chamfering process.According to same principle, along with withdrawing from of drilling tool, the rear edge of two-way chamfering tool 6 to certain depth, and makes two-way chamfering tool 6 move by above-mentioned operation principle the another port chamfering in the hole of being bored, thereby finishes the once boring-two-way chamfering work period.
Embodiment 2
As Fig. 2 (a) with (b).This drilling tool comprises drillstock 1, drill body 2 and drill bit 7 etc.The back of the body of boring 9 and chip area 8 are arranged on the drill body.Drill bit 7 is positioned at drill body 2 front ends.The two-way facing attachment of one cover elasticity is respectively arranged on two brill back ofs the body 9, by groove 10, boss 3, elasticity lattice framing 5, compositions such as two-way chamfering tool 6 and screw 4.Groove 10 is positioned at and bores on the back of the body 9, and boss 3 is positioned at the inner (also can be located at the outer end) of groove 10.One termination of elasticity lattice framing 5 has two-way chamfering tool 6, and its other end is fixed on the boss by screw 4.
When work, one is advanced brill-withdrawing working cycles, the dynamic duty principle similar embodiment 1 of the two-way facing attachment of two cover elasticity, but, effect is better than embodiment 1, have the chamfering high efficiency, has overcome the advantages such as influence of single assembly accident to the working time.
Embodiment 3
As Fig. 3 (a) with (b).The structure similar embodiment 2 of this drilling tool.The two-way facing attachment of a cover elasticity that different is wherein makes elasticity mill engagement positions into, that is: change two-way chamfering tool 6 into grinding tool 11, and the forward and backward working face of grinding tool 11 lags behind the forward and backward working face of the two-way chamfering tool 6 of the two-way facing attachment of corresponding elasticity respectively.
During work, the operation principle similar embodiment 2 of two-way facing attachment and elasticity mill engagement positions.Different is in advancing the brill process, is to carry out chamfering by the front edge of two-way chamfering tool 6 earlier, then puts in order the angle that mill is fallen by grinding tool 11, and spark-out is carried out in the hole of being bored.In the withdrawing process, then earlier by the rear edge of the two-way chamfering tool 6 another port chamfering to the hole of being bored, then the angle of being fallen by grinding tool 11 whole mills is ground to put in order to endoporus at last and is processed.
The advantage of this drilling tool is, advancing brill-withdrawing in work period, finished the whole manufacturing procedure of boring-two-way chamfering-mill; Improved the fineness of two-way chamfered bore machined surface.
