Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
It please refers to Fig.1 to Fig.3, magnetic clamp provided by the present embodiment, comprising: magnetic conduction pedestal 3, permanent magnet 1 and a pair
Every magnet 2;Magnetic conduction pedestal 3 includes the locating slot 31 of inner cavity and a pair of opposing, and locating slot 31 is set on internal chamber wall, every magnetic
Body 2 is arranged in locating slot 31, and permanent magnet 1 is inserted in inner cavity and connects with the 360 ° of rotations of its internal chamber wall;
Permanent magnet includes south and north poles, south and north poles and magnetic clamp loss of excitation, south and north poles when magnet 2 contacts
Separate magnetic clamp when magnet 2 has magnetism.
According to electromagnet principle, the electric current in coil is bigger, and the suction of magnetic holding device is bigger.This is because working as the magnetic of coil
Induction B is directly proportional to electric current I, so that magnetic flux increases.A large amount of magnetic induction line is flowed out from coil to be returned after workpiece
Closed circuit is formed in coil, so that workpiece is magnetized, is finally sucked.
In magnetics, Rm=Um/ φ, magnetic flux φ is directly proportional to magnetomotive force Um in magnetic circuit, is inversely proportional with magnetic resistance Rm.This is practical
