To in the processing scheme of special pinhole, it is fast that piezoceramic material has speed responsive at present, and boring bar is active in one's movements, but when piezoelectric ceramics rotates with main shaft, power supply difficulty, adopts the brush way of contact, is difficult to meet the requirement of high speed boring.Giant magnetostrictive material is as a kind of novel intelligent material, has that driving force is large, coefficient of dilatation is large, power density is high, a fast response time, controllable precision high, obtained application very widely.
Utility model content
The purpose of this utility model is to provide the intelligent boring bar that a kind of giant magnetostrictive material drives, under the effect in magnetic field, giant magnetostrictive rod can extend and shorten, drive boring bar to produce axial deflection, make cutter form radial feed displacement, to realize the boring processing of special pinhole.
The technical solution of the utility model is as follows:
The intelligent boring bar that a kind of giant magnetostrictive material drives, include static pressure boring spindle, it is characterized in that: on described static pressure boring spindle, be installed with holder, on described holder, be installed with respectively, lower magnet exciting coil support, on described, on lower magnet exciting coil support, be installed with respectively, lower giant magnetostrictive rod, on, on lower magnet exciting coil support respectively upper, the outside correspondence of lower giant magnetostrictive rod is wound with magnet exciting coil, on described, between lower giant magnetostrictive rod, be fixedly connected with boring bar, the front end of described boring bar is fixedly connected with cutter.
The intelligent boring bar that described giant magnetostrictive material drives, it is characterized in that: on described upper and lower magnet exciting coil support, be respectively equipped with screw, on described holder, be respectively equipped with the through hole corresponding with screw on described upper and lower magnet exciting coil support, there is screw pass respectively corresponding through hole and screw and be screwed in screw, described upper and lower magnet exciting coil support is fixedly mounted on respectively on described holder.
The intelligent boring bar that described giant magnetostrictive material drives, is characterized in that: between the magnet exciting coil support at the two ends of described magnet exciting coil and place, be flexible connection.
The beneficial effects of the utility model:
1, the utility model adopts the design of boring spindle, holder, magnet exciting coil support, giant magnetostrictive rod and boring bar combination, provides boring cutter under the driving of giant magnetostrictive rod, to produce radially micro-feeding, conveniently realizes the processing of profiled-cross-section pin-and-hole.
2, the utility model adopts electromagnetic induction principle to realize the design driving, simple and easy to do in the time that control giant magnetostrictive rod is flexible.
3, the utility model adopts two designs that giant magnetostrictive rod is used in combination, take full advantage of that giant magnetostrictive rod driving force is large, coefficient of dilatation is large, power density is high, fast response time, feature that controllable precision is high, it is greatly improved in precision control than the mode that adopts the monolateral driving of single giant magnetostrictive rod.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Referring to Fig. 1, the intelligent boring bar that a kind of giant magnetostrictive material drives, include static pressure boring spindle 1, on static pressure boring spindle 1, be installed with holder 3, on holder 3, be installed with respectively, lower magnet exciting coil support 4, 8, on, lower magnet exciting coil support 4, on 8, be installed with respectively, lower giant magnetostrictive rod 6, 9, on, lower magnet exciting coil support 4, on 8 respectively upper, lower giant magnetostrictive rod 6, 9 outside correspondence is wound with magnet exciting coil 5, on, lower giant magnetostrictive rod 6, between 9, be fixedly connected with boring bar 7, the front end of boring bar 7 is fixedly connected with cutter.
In the utility model, on upper and lower magnet exciting coil support 4,8, be respectively equipped with screw, on holder 3, be respectively equipped with the through hole corresponding with screw on upper and lower magnet exciting coil support 4,8, there is screw 2 pass respectively corresponding through hole and screw and be screwed in screw, upper and lower magnet exciting coil support 4,8 is fixedly mounted on respectively on holder 3; Between the magnet exciting coil support at the two ends of magnet exciting coil 5 and place, be flexible connection, can make boring bar 7 realize easily radial feed along with the distortion of upper and lower giant magnetostrictive rod 6,9.
In the utility model, upper and lower magnet exciting coil support 4,8 is arranged symmetrically with respect to the axis of static pressure boring spindle 1.
Pass into electric current to magnet exciting coil 5, control respectively its size of current, make in the time that upper giant magnetostrictive rod 6 extends, lower giant magnetostrictive rod 9 will shorten, and the stroke equal and opposite in direction of the two, otherwise is also like this.Realize the size and dimension boring processing of noncircular pin hole.By relevant parameter is rationally set, can meet the technical requirement of various micro-feeding processing strokes.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
