Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is described in detail:
As shown in Figure 1-2, a kind of electromagnetism claw centring means, electromagnet 1 is fixed on chuck seat 5 side, permanent magnet 2 and the slip frustum of a cone 3 link together, there are three chuck jaws be circularly and evenly distributed 4 at the slip frustum of a cone 3 conical surface place, chuck jaw 4 extends radially out along chuck seat 5, at each position spring 7 once of chuck jaw 4 end on chuck seat 5 outer wall, and be connected on chuck jaw 4, chuck seat 5 inwall least significant end is equipped with a limit body 6, when electromagnet 1 passes into forward current, the permanent magnet 2 be fixed on the slip frustum of a cone 3 pushes the slip frustum of a cone 3 under the effect of electromagnet 1 repulsion, the slip frustum of a cone 3 moves forward, chuck jaw 4 on its conical surface is subject to the thrust on outwards top, electric current in electromagnet 1 increases, the thrust that the slip frustum of a cone 3 pushes chuck jaw 4 increases, thrust exceedes return spring 7 pulling force, three chuck jaws 4 are ejected by the slip frustum of a cone 3 and mobile range is consistent, under the slip frustum of a cone 3 ejecting force effect, chuck jaw 4 moves to and is adjacent to when centering round tube inner wall, complete centering, electromagnet 1 passes into current in opposite, and produce the magnetic field attracted with permanent magnet 2, permanent magnet 2 drives the slip frustum of a cone 3 of chuck seat 5 inside to move backward under electromagnet suction effect, chuck jaw 4 homing under the effect of return spring 7, and centring means shrinks, limit body 6 is that the slip frustum of a cone 3 is spacing, for centring means provides protection.
Electromagnet 1 on centring means leads to rightabout electric current and produces rightabout magnetic field, thrust or suction is produced under the effect of permanent magnet, power is applied to the slip frustum of a cone 3, under the mating reaction of return spring 7, realize stretching out and return of chuck jaw 4, complete distending and the contractive action of centring means.
Electromagnet 1 on centring means passes into the electric current of different directions to produce electromagnetic push or electromagnetic attraction, controlled translational speed and the force size of the slip frustum of a cone 3 by the electric current passing into different current value, thus control chuck jaw 4 speed of stretching out and the size that exerts a force.
Three chuck jaws 4 on positioner stretch out when being subject to the thrust of the slip frustum of a cone 3 simultaneously, automatically set back during stressed disappearance under return spring 7 acts on; Three chuck jaws 4 are ejected when the slip frustum of a cone 3 moves forward and to eject amplitude consistent.
Carried out the moving range of the limit slippage frustum of a cone 3 by limit body 6, prevent off-limits motion from producing unpredictable consequence, guarantee that centring means normally runs.
Operation principle: electromagnet 1 is fixed on the chuck seat 5 of centring means side, permanent magnet 2 and the slip frustum of a cone 3 are connected together.When electromagnetic wire iron 1 passes into forward current, permanent magnet 2 is subject to the pushing active force of electromagnet 1, the slip frustum of a cone 3 moves forward, when the thrust of the slip frustum of a cone 3 pairs of chuck seats 4 is greater than the pulling force of return spring 7 pairs of chuck jaws 4, chuck jaw 4 is protruding, when three chuck jaws extend out to the tube wall be adjacent to wait pipe of feeling relieved simultaneously, centring means distending, completes centering operation.Pass into reversing the current to electromagnet 1, permanent magnet 2 is subject to the attraction force of electromagnet 1, and permanent magnet 2 sets back with the slip frustum of a cone 3, and chuck jaw 4 sets back under return spring 7 acts on, and centring means shrinks.
The present invention, realizes, to the quick control of centring means, under the prerequisite not affecting centering precision, simplifying the structure, achieving centering function for core with electromagnet 1, has and controls simply, fast easy to operate, efficient feature of feeling relieved.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
