Description
Technical field
The present invention relates to a kind of magnetic holding device for lathe.
Background technology
At present, the shortcomings of lathe is generally clamped using the self-centering manual of mechanical three-pawl type to workpiece, and it is present, and clamping workpiece is slow, efficiency is low, workpiece deformation is big, clamping force hardly possible control；There is electromagnetic type fixture later, but it has that structure is complex, positioning to workpiece is insecure, adjusts and changes the shortcomings of inconvenient.
The content of the invention
It is an object of the invention to the above-mentioned deficiency for prior art, there is provided a kind of magnetic holding device, it had both had the advantages of clamping workpiece is fast, the deformation of efficiency high, workpiece is small, while structure is relatively easy, firm position to workpiece, and was conveniently adjusted and changes.
To reach above-mentioned purpose, the magnetic holding device of the present invention, including hollow magnetic core, the clamp body being placed on outside magnetic core, the cover plate being fixed on clamp body, clamp body is provided with annular groove, it is characterized in that permanent magnet is provided with the annular groove of clamp body, magnetic core and the magnetic pole of its outer end are fixedly connected, and clamp body, magnetic core, magnetic pole are magnetic conductor；Semicircular terminal pad is also fixedly connected with clamp body, terminal pad is connected by bolts and nuts with two fulcrum bearings, and each fulcrum bearing is all connected with a rest pad, and two rest pads set in an angle and are located at below magnetic pole, and the head of two rest pads is every magnet.
During use, magnetic core is coupled with machine tool chief axis, clamp body couples with machine tool end cover, and permanent magnet causes clamp body, magnetic core, magnetic pole to take magnetic, and workpiece is adsorbed on magnetic pole end face by the slightly biased heart, two rest pads contact with workpiece simultaneously, support is provided it, and structure of the present invention is relatively easy, firm position to workpiece, and whole process clamping workpiece is fast, efficiency high, and workpiece is not small by chucking power, deformation；
As a further improvement on the present invention, it is additionally provided between magnetic core and magnetic pole and passes sequentially through bolt connection for the disk of magnetic conductor, magnetic core, disk, magnetic pole；It is conveniently replaceable the magnetic pole of different model；
As a further improvement on the present invention, each fulcrum bearing is equipped with chute with corresponding rest pad, and the chute direction of the two intersects, and fulcrum bearing is connected with corresponding rest pad by the bolt and lock nut being placed in the two chute；By position of the adjustment bolt in two chutes, the position of rest pad is can adjust, expands the scope of application of this fixture；
As a further improvement on the present invention, arc chute is provided with terminal pad, terminal pad is placed in the arc chute with the head of the bolt of corresponding fulcrum bearing；By adjusting position of the bolt in arc chute, the angle of two rest pads is can adjust, expands the scope of application of this fixture；
In summary, the present invention had both had the advantages of clamping workpiece is fast, the deformation of efficiency high, workpiece is small, while structure is relatively easy, firm position to workpiece, and was conveniently adjusted and changes.
Brief description of the drawings
Fig. 1 is the front view of the embodiment of the present invention.
Fig. 2 is Fig. 1 right view.
Embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
Such as Fig. 1, shown in Fig. 2, the electric magnetic no-core clamp, including hollow magnetic core 1, the clamp body 2 being placed on outside magnetic core 1, the cover plate 3 being fixed on clamp body 2, clamp body 2 is provided with annular groove, permanent magnet 4 is provided with the annular groove of clamp body 2, magnetic core 1 and the disk 5 of its outer end are bolted, disk 5 and the magnetic pole 6 of its outer end are bolted, clamp body 2, magnetic core 1, disk 5, magnetic pole 6 is magnetic conductor, semicircular terminal pad 8 is also fixedly connected with by bolt on clamp body 2, arc chute 8a is provided with terminal pad 8, terminal pad 8 is connected by two bolts 9 with nut with two fulcrum bearings 10, the head of the bolt 9 is placed in arc chute 8a；Each fulcrum bearing 10 is all connected with a rest pad 11, and each fulcrum bearing 10 is equipped with chute with corresponding rest pad 11, and the chute direction of the two intersects, and fulcrum bearing 10 is connected with corresponding rest pad 11 by the bolt 12 and locking nut being placed in the two chute；Two rest pads 11 set in an angle and are located at the lower section of magnetic pole 6, and the head 11a of two rest pads 11 is every magnet, such as hard alloy.
In use, magnetic core 1 is coupled with machine tool chief axis, clamp body 2 couples with machine tool end cover, permanent magnet 4 causes clamp body 2, magnetic core 1, disk 5, magnetic pole 6 to take magnetic, workpiece 13 is adsorbed on the end face of magnetic pole 6 by the slightly biased heart, while two rest pads 11 are contacted with workpiece 13, and support is provided to it；By position and bolt 9 position among arc chute 8as of the adjustment bolt 12 in two chutes, the position of rest pad 11 and the angle of two rest pads 11 are can adjust, expands the scope of application of this fixture；The present invention had both had the advantages of clamping workpiece is fast, the deformation of efficiency high, workpiece is small, while structure is relatively easy, firm position to workpiece, and was conveniently adjusted and changes.
