Body 13 is connected, and the other end of swing arm 14 stretches out to be connected outside housing 11 with pulling handle 15.
Rotation direction of the invention by pulling handle 15, magnetic circuit switch, reaches work purpose.Permanent magnetic chuck is to utilize magnetic
What the logical principle of continuity and magnetic field superposition theorem were designed, the magnetic Circuit Design of permanent magnetic chuck passes through magnetic system into multiple magnetic systems
Relative motion, realizes the addition of magnetic field intensity or cancellation on work magnetic pole strength, so as to reach the purpose of sticking and unloading.
As shown in Figure 11,12, when permanent magnetic chuck magnetic pole is in Figure 11 states, the magnetic line of force is from magnet for operation principle of the present invention
N poles come out, by yoke, by ferromagnetic workpiece 6, return the S poles that yoke enters magnet.So, just can be the jail of workpiece 6
Inhale firmly on the work pole-face of permanent magnetic chuck.When magnetic pole is in Figure 12 states, work pole of the magnetic line of force less than permanent magnetic chuck
Face, the closed-loop path of magnetic circuit is just constituted inside permanent magnetic chuck, is almost gone out without the magnetic line of force from the work pole-face of permanent magnetic chuck
Come, so suction will not be produced to workpiece 6, just can smoothly realize unloading.Permanent magnetic chuck uses high performance permanent magnetic materialses neodymium iron boron
(Nd-Fe-B)For product kernel, small product size is small, and magnetic force is permanent not to wane.Work pieces process is finished, and pulls handle 15, along counterclockwise
180 are rotated to arrive " OFF ", you can demagnetization is completed, permanent magnetic chuck is removed safely.
Another embodiment of the present invention:Acetabula device can be made using vacuum cup.
Above-described embodiment is preferably embodiment, but embodiments of the present invention are not by above-described embodiment of the invention
Limitation, other any Spirit Essences without departing from the present invention and the change made under principle, modification, replacement, combine, simplification,
Equivalent substitute mode is should be, is included within protection scope of the present invention.
