Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As depicted in figs. 1 and 2, magnetic clutch of the present invention comprises support 1, first permanent magnet 2, second permanent magnet 3, slideway 4, coil 5, slide block 6, push rod 7, Detecting element 8 and power supply 9.
The boss that support 1 comprises base plate, two lateral retaining plates and is positioned in the middle part of support 1, wherein a lateral retaining plate has a hole.
A hole is had in the middle part of second permanent magnet 3, second permanent magnet 3 is arranged on the inner side of the baffle plate of perforate, first permanent magnet 2 is arranged on the inner side of opposite side baffle plate, on second permanent magnet 3, on the center line in hole, baffle plate, the center line in hole and the center line of push rod 8 overlap, and the first permanent magnet 2 and the second permanent magnet 3 same polarity are in opposite directions.
Slideway 4 is fixed on boss, and boss is all stretched out in the two ends of slideway 4.
Coil 5 is wound on the two ends of slideway 4 in the same way.
Slide block 6 is arranged in slideway 4, and the right-hand member of slide block 6 has a hole, and one end of push rod 7 is fixedly mounted in the hole of slide block 6, and the other end passes in the hole from the second permanent magnet 3 and on baffle plate.
Detecting element 8 for detecting the position of slide block 6, and generates position signal;
Power supply 9 for by given from, close signal and come the conducting of control coil 5 and electric current commutation, and automatically control it by position signal and turn off.
In the present embodiment, support 1 and slide block 6 are formed by magnetic conductive metal materials processing, and push rod 7 adopts non-magnetic metallic material.
In other mode of executions of the present invention, friction pair can be equipped with at the other end of push rod 7 and form friction clutcch, or equipped dental inlay pair forms jaw clutch, or equipped sliding pair forms aixs cylinder formula clutch, also can become by the electromagnetic clutch unit combination of m above-mentioned mode of execution the magnetic clutch etc. that an output torque m doubly amplifies, in a word, can do to dispose flexibly according to practical application request, repeat no more herein.
Working principle of the present invention is explained referring to Fig. 2:
With N pole in opposite directions, slide block 6 maintains static under the attraction of the first permanent magnet 2 for first permanent magnet 2 and the second permanent magnet 3, and now clutch relies on permanent magnet magnetic pulling force to form "Off" stable state, and coil 5 is in off-position.To power supply 9 " conjunction " signal, make to pass into directional current from left to right in coil 5, then induce the polarity of the right S of left N in slide block 6; First permanent magnet 2 pairs slide block 6 produces magnetic repulsion, and the second permanent magnet 3 pairs slide block 6 produces magnetic pull, and formed and make a concerted effort to the right, slide block 6 moves to the right, promotes push rod 7 and stretches out outside the second permanent magnet 3 and support 1; When slide block 6 is through right side Detecting element 8, position signal triggering voltage 9 turns off, coil 5 power-off, and slide block 6 relies on permanent magnet magnetic pulling force to continue motion and final and the second permanent magnet 3 adhesive, stable state that magnetic clutch enters " conjunction ".
Otherwise, when magnetic clutch is in " conjunction " stable state, given "Off" signal, then power supply 9 passes into right-to-left directional current in coil 5, and slide block 6 is right-to-left motion under magnetic force, drive push rod 7 to retract in support 1 simultaneously, before slide block 6 moves to left side and the first permanent magnet 2 adhesive, by the position signal power cutoff 9 of slide block 6, coil 5 power-off, slide block 6 relies on permanent magnet magnetic pulling force finally to move to and the first permanent magnet 2 adhesive, and magnetic clutch enters "Off" stable state.
