Abstract

The utility model relates to an electric magnet/permanent magnet clamping tool, which is composed of an irreversible magnet (1), a reversible magnet (3) which is arranged below the irreversible magnet, an electromagnetic coil (2) which is sheathed on the exterior of the reversible magnet, and a shell body (4), wherein, the irreversible magnet and the reversible magnet are arranged between magnetic collection and guide bodies (5). Inner and outer magnetic circuits are closed by changing the current direction of the electromagnetic coil (2), and a work piece (6) is absorbed firmly or released. The utility model has the advantages of strong suction, single-surface suction, multi-surface processing, high safety, no electricity, no temperature rise, high precision and simple operation.

Description

Electricity permanent magnetism anchor clamps
Technical field
The utility model relates to a kind of electric permanent magnetism anchor clamps, a kind ofly is applied on the numerical control machining center to rely on magnetic force workpiece to be positioned the fixture of processing.
Background technology
The novel magnetic sucker of existing electric permanent magnetism anchor clamps such as patent 90219355.4 band magnetising or demagnetising apparatus, its disclosed content characteristic is the magnechuck iron core to be removed changed reversible magnetic body into, reaches to protect the effect that magnetic uses, its shortcoming is:
1, has only a kind of reversible magnetic body in the magnetic circuit, will will just can take off workpiece after the complete demagnetization of reversible magnetic body during to table top and workpiece degaussing, degausser is required height, circuit complexity.
2, owing to have only a kind of reversible magnetic body, magnetic circuit is single, and magnetic force is on the weak side, can not satisfy the instructions for use of lathe high-rate cutting.
Summary of the invention:
The utility model electricity permanent magnetism anchor clamps are to provide a kind of and fill demagnetization simply, a kind of a kind of magnetic force positioning fixture that can satisfy lathe high-rate cutting processing needs that magnetic force is bigger.
This utility model electricity permanent magnetism anchor clamps, the electric permanent magnetism anchor clamps of forming by solenoid (2), reversible magnetic body (3), irreversible magnet (1), housing (4) and workpiece table top.Be in formation, to have increased newly irreversible magnet (1) with the prior art difference.Adopted irreversible magnet (1) and reversible magnetic body under the effect of solenoid (2) magnetic field, to form the serial or parallel connection form on its magnetic structure, behind solenoid (a 2) logical forward current of moment, give the reversible magnetic body (3) place solenoid (2) fill with the opposite magnetic field of irreversible magnet (1) direction, irreversible magnet loop and reversible magnetic body magnetic circuit two magnetic circuits are by collection magnetic conductance magnet (5), form parallel circuits through workpiece (6) and housing (4) on the anchor clamps table top, when solenoid (2) moment during a logical reversing the current, give the reversible magnetic body (3) place solenoid (2) fill with the identical magnetic field of irreversible magnet (2) direction, irreversible magnet magnetic circuit and reversible magnetic body magnetic circuit form closed series circuit by leading pole (5) workpiece (6) on the anchor clamps table top in enclosure interior.
Because adopted irreversible magnet and connection in series-parallel magnetic structure in the magnetic circuit, the double magnetic circuit effect can increase 1/3rd for reaching 50N/mm than prior art magnetic force 2, only needing oppositely same electric current for degaussing, the magnetic pole of reversible magnetic body fully oppositely reaches interior flux equivalent, workpiece easily can be taken off.

The specific embodiment
Be illustrated from embodiment below:
The table top of electricity permanent magnetism anchor clamps is formed the little magnetic pole strength of a plurality of rectangles by collection magnetic conductance magnet (5), and collection magnetic conductance magnet (5) is a cuboid, and its length and width height is respectively 60 * 60 * 70mm 3, the side of collection magnetic conductance magnet accompanies 50 * 60 * 12mm 3Irreversible magnet (1), the Nd-Fe-B magnet steel manufacturing of irreversible magnet is placed with reversible magnetic body (3) between collection magnetic conductance magnet (5) and housing, and irreversible magnet is made with alnico magnet.Reversible magnetic body (3) is outer to be with solenoid (2), is filled with high rigidity insulating resin glue (7) in other space in housing (4), draws housing behind the coil series and parallel respectively, is used for place work piece (6) after electric permanent magnetism anchor clamps upper table surface polishes.

Claims (3)

1, electric permanent magnetism anchor clamps are made up of reversible magnetic body (3), irreversible magnet (1), solenoid (2), housing (4) collection magnetic conductance magnet (5); It is characterized in that having on the electric permanent magnetism anchor clamps table top the little magnetic pole strength of rectangle of the rule of forming by collection magnetic conductance magnet (5).
2, electric permanent magnetism anchor clamps according to claim 1; It is characterized in that collecting between magnetic conductance magnet (5) side and be placed with irreversible magnet (1).
3, electric permanent magnetism anchor clamps according to claim 1; It is characterized in that irreversible magnetic conductor (1) makes with Nd-Fe-B magnet steel.
