Description
Technical field
The present invention relates to magnet ring to magnetize technical field, especially relate to the multipole magnetized device of a kind of magnet ring.
Background technology
Along with the application of magnetic material is increasingly extensive, the product category of the customer requirement magnetization supply of material, quantity are more and more, and magnetization requires more and more higher, therefore make requirement facing to magnetic holding device more and more higher. There is certain gap between the general each cartridge of multipole magnetization device, when magnetizing assembly uses, interference easily touched by the coil being wound around between adjacent cartridge, causes unexpected. And adding after insulation filler separates, the magnetizing coil on each cartridge is after long discharge and recharge, and coil is through constantly expanding contraction, and the implant of solidification very easily produces crack at the gap location of cartridge, thus terminating the useful life of magnetising fixture in advance.
Such as Chinese patent Authorization Notice No.: CN2399807, in the patent document in authorized announcement date on October 04th, 2000, disclosing a kind of magnetizing clamp, fixture includes magnetize chuck, coil, radially uniform the more than one pair of chuck that magnetizes of the magnetic conduction iron yoke of annular; Magnetize sheathed coil rack on chuck, and on skeleton, coil in winding. This fixture being used for entirety magnetize and carry out magnetic saturation, make the maximum magnetostatic moment of magnetic coupler be greatly improved, horsepower is more powerful, and is absent from demagnetization problem; Ensure that the crudy of workpiece, make magnetic force driving pump can be widely used for the medium that delivery ratio is great, viscosity is big. But magnetizing of this magnetizing clamp exists multiple gap between chuck, if there being implant between gap, long-time use after, the implant in gap, easily because the expansion of coil is shunk produces crack, affects magnetizing clamp service life.
Summary of the invention
The present invention has gap and gap inner stuffing deficiency easy to crack to overcome between general multipole magnetized device cartridge, provide and a kind of eliminate gap, prevent the multipole magnetized device of magnet ring of gap inner stuffing cracking, provide a kind of design convenient, the simple new method of manufacturing process simultaneously.
To achieve these goals, the present invention is by the following technical solutions:
A kind of multipole magnetized device of the magnet ring of the present invention, including annular ring and magnetization cartridge, the magnetization cartridge of two pairs or more than two even-evens of uniformly arranging in annular ring inner radial, magnetization cartridge is wound with coil, being provided with non-magnetic inserted sheet between adjacent magnetization cartridge, the adjacent fan-shaped space between magnetization cartridge is filled with insulant.
The present invention is packed into insulant in the gap of adjacent magnetization cartridge, it is to avoid during use, adjacent windings contacts interference because of expansion.Present invention creativeness between each magnetization cartridge adds not magnetic conduction inserted sheet such as copper, the inserted sheet that magnetic conductive metal material is not made such as magnetism-free stainless steel, it is used for the gap shielding between each magnetization cartridge, it is wrapped in the coil on magnetization cartridge, constantly expand at continual charge and discharge process coil and shrink, insulant after the solidification surround surrounding ceaselessly produces extruding, because having certain gap between magnetization cartridge, rigid material burden Extendable cycles is not had to produce outside thrust in the middle of gap, produced thrust is eliminated by insulant self, therefore very easily crack is produced at gap location, not magnetic conduction rigid metallic material is utilized to be made after space shields by inserted sheet, produced thrust kept out jointly by insulant after inserted sheet and solidification, the insulant after solidifying is avoided to produce crack after expansion for a long time is shunk. inserted sheet prevents coil landing on magnetization cartridge simultaneously.
As preferably, the pair of magnetization cartridge refers to the magnetization cartridge of diametrically symmetrical two homopolarities of annular ring one, adjacent magnetization cartridge be N pole and S extremely spaced apart.
As preferably, magnetization cartridge is cylindrical, and magnetization cartridge one end connects annular ring, and magnetization cartridge the other end is the arc of indent, and the curved end of multiple magnetization cartridges is centrally formed the cavity of interior round shape at annular ring. Several magnetization cartridge ends are arc so that cavity edge, in rule shape circular arc, facilitates built-in magnet ring.
As preferably, magnetization cartridge is truncated cone-shaped, and the big rounded ends of magnetization cartridge connects annular ring, and the magnetization little rounded ends of cartridge is the arc of indent, and multiple little rounded ends of magnetization cartridge are centrally formed the cavity of interior round shape at annular ring. Several magnetization cartridge ends are arc so that cavity edge, in rule shape circular arc, facilitates built-in magnet ring. The magnetization cartridge of truncated cone-shaped meets magnetizing assembly diameter from outside to inside and diminishes trend, is more beneficial for the arrangement of multiple magnetization cartridge. And coil produces the number of turn of size and coil in magnetic field and flows through the electric current of coil and be directly proportional, unrelated with the diameter of coil, do not affect and magnetize.
As preferably, magnetization cartridge is provided with slot away from the both sides, end of annular ring, and inserted sheet is arc, and inserted sheet two ends are plugged in the slot of two adjacent magnetization cartridges.
As preferably, the coil density that each magnetization cartridge is wound with is consistent. Ensure multipole magnetized uniformity.
As preferably, described insulant is resin.
There is advantages that gap between elimination magnetization cartridge; Prevent insulant cracking in gap.
