Description
Technical field
The present invention relates to the magnet ring technical field that magnetizes, especially relate to a kind of multipole magnetized device of magnet ring.
Background technology
Along with the application of magnetic material is increasingly extensive, product category, the quantity of the customer requirement magnetization supply of material get more and more, and magnetization requires more and more higher, therefore facing to magnetic holding device making, requires more and more higher.Between general each cartridge of multipole magnetization device, exist certain gap, when magnetizing assembly uses, the coil being wound around between adjacent cartridge is easily touched interference, causes unexpected.And after adding insulation filler to separate, the magnetizing coil on each cartridge is after discharging and recharging for a long time, coil is through constantly expansion contraction, and curing filler very easily produces crack at the gap location of cartridge, thereby finishes in advance to magnetize the useful life of fixture.
As Chinese patent Granted publication number: CN2399807, in the patent document in October 04 2000 Granted publication day, a kind of magnetizing clamp is disclosed, fixture comprises the chuck that magnetizes, coil, the footpath of magnetic conduction iron yoke of annular uniform the more than one pair of chuck that magnetizes that makes progress; Sheathed the coil rack on chuck that magnetizes, on skeleton, coil in winding.This fixture is magnetized and carries out magnetic saturation for integral body, the maximum magnetostatic moment of magnetic coupler is improved greatly, horsepower is more powerful, and does not have demagnetization problem; Guaranteed the crudy of workpiece, made magnetic force driving pump can be widely used in the medium that delivery ratio is great, viscosity is large.But magnetizing of this magnetizing clamp exists a plurality of gaps between chuck, if there is filler between gap, after long-time use, the filler in gap easily produces crack because the expansion of coil is shunk, and affects magnetizing clamp useful life.
Summary of the invention
The present invention is in order to overcome gapped between general multipole magnetized device cartridge and gap inner stuffing deficiency easy to crack, provide a kind of and eliminated gap, prevented 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:
The multipole magnetized device of a kind of magnet ring of the present invention, comprise annular ring and magnetization cartridge, the magnetization cartridge of two pairs or the two above even-evens of evenly arranging in annular ring inner radial, on magnetization cartridge, be wound with coil, between adjacent magnetization cartridge, be provided with non-magnetic inserted sheet, the fan-shaped space between adjacent magnetization cartridge is filled with insulating material.
The present invention is packed into insulating material in the gap of adjacent magnetization cartridge, and while avoiding using, adjacent windings contacts interference because of expansion.The present invention's creativeness between each magnetization cartridge adds not magnetic conduction inserted sheet as copper, the inserted sheet that magnetic conductive metal material is not made such as magnetism-free stainless steel, be used for shielding and respectively magnetize the gap between cartridge, be wrapped in the coil on magnetization cartridge, at the continuous enlargement and contraction of continual charge and discharge process coil, surrounding is surrounded solidify after insulating material ceaselessly produce extruding, because having certain gap between magnetization cartridge, in the middle of gap, do not have rigid material opposing coil expander to produce outside thrust, by insulating material self, eliminate the thrust producing, therefore very easily at gap location, produce crack, after utilizing not magnetic conduction rigid metallic material to make inserted sheet space is shielded, inserted sheet and solidify after insulating material jointly keep out produced thrust, avoid the insulating material after solidifying after expansion contraction, producing crack for a long time.Inserted sheet prevents coil landing on magnetization cartridge simultaneously.
As preferably, described a pair of magnetization cartridge refers to the magnetization cartridge of two homopolarities symmetrical on diameter of annular ring, and adjacent magnetization cartridge is that the N utmost point and S are extremely spaced apart.
As preferably, magnetization cartridge is cylindrical, magnetization cartridge one end connecting ring shape circle, and the arc that magnetization cartridge the other end is indent, the curved end of a plurality of magnetization cartridges forms the cavity of inner circle shape in annular ring central authorities.Several magnetization cartridges end is arc, makes cavity edge be regular shape circular arc, facilitates built-in magnet ring.
As preferably, magnetization cartridge is truncated cone-shaped, the large rounded ends connecting ring of magnetization cartridge shape circle, and the arc that the little rounded ends of magnetization cartridge is indent, the little rounded ends of a plurality of magnetization cartridges forms the cavity of inner circle shape in annular ring central authorities.Several magnetization cartridges end is arc, makes cavity edge be regular shape circular arc, facilitates built-in magnet ring.The magnetization cartridge of truncated cone-shaped meets the magnetizing assembly diameter trend that diminishes from outside to inside, is more conducive to a plurality of magnetization cartridges and arranges.And coil produces the size in magnetic field and the number of turn of coil is directly proportional with the electric current that flows through coil, irrelevant 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 being wound with on each magnetization cartridge is consistent.Guarantee multipole magnetized uniformity.
As preferably, described insulating material is resin.
The present invention has following beneficial effect: eliminate gap between magnetization cartridge; Prevent insulating material cracking in gap.
