Description
Technical field
The present invention relates to clamping apparatus field, more particularly to a kind of electric permanent magnet.
Background technology
In mechanical manufacturing field, by magnetic-adsorption to workpiece carry out clamping magnetic suction disc because
The advantage such as economic and environment-friendly and be widely applied.
At present, magnetic suction disc has permanent magnet sucker, electromagnet sucker and electric permanent-magnet suction disc etc. many
Plant concrete form.A kind of typical magnetic suction disc is permanent magnet sucker, in such a permanent magnet sucker
Including fixed magnetic system and activity magnetic system, using the state of external force change activity magnetic system, work is realized
The superposition of magnetic field intensity or cancellation on platform, so as to realize sticking to machined part or unloading.
However, such a magnetic suction disc needs to carry out magnetic pole switching by external force when in use, behaviour
Make more inconvenient, the automaticity for letting off process control for workpiece to be added suction is relatively low.
Therefore, the operation of magnetic suction disc is more facilitated, be that those skilled in the art are current
The technical issues that need to address.
The content of the invention
In view of this, it is an object of the invention to provide a kind of electric permanent magnet, the electric permanent magnet is in behaviour
More facilitate when making.
To achieve the above object, the present invention provides following technical scheme：
A kind of electric permanent magnet, includes the housing and the permanent-magnet pieces in the housing of magnetic conduction, also
Including for producing the coil block of electromagnetic field and for controlling the electric current in the coil block
Electrically-controlled component, the coil block insulation is described under suction state in the housing
Coil block is remained powered on and the electromagnetic field and permanent magnetic field are in the same direction.
Preferably, the coil block is located at the downside of the permanent-magnet pieces of ring-type, the coil
Electromagnetic wire in component around the circumferentially disposed of the central shaft of the permanent-magnet pieces, the permanent-magnet pieces it is interior
Anchor ring and outer ring surface are respectively two pole-faces of the permanent-magnet pieces.
Preferably, the coil block includes the electromagnetic wire, for the electromagnetic wire winding
The bobbin of the insulation of ring-type, the insulation at two ends in the axial direction of the bobbin
Ring-type end plate and the insulating barrier located at the top layer of the electromagnetic wire.
Preferably, iron core is also included in the coil block.
Preferably, offered on the roof of the housing for placing the permanent-magnet pieces and the line
The endless groove of coil assembly.
Preferably, the coil block is the scope of control voltage in DC voltage 12V to 36V
Between coil block.
Preferably, the gap between the coil block and the housing is filled with inserts.
Preferably, the housing is cylinder.
The electric permanent magnet that the present invention is provided includes housing, coil block, permanent-magnet pieces and electrically-controlled component.
Under suction state, i.e., under the working condition of electric permanent magnet sticking workpiece to be added, to electric permanent magnet
The electric current of direction initialization is passed through, the permanent magnetism for making the electromagnetic field that coil block is produced be produced with permanent-magnet pieces
The direction of field is identical, and two magnetic fields are mutually exclusive, treated due to being placed with the workbench of electric permanent magnet
Workpiece, promotes the permanent magnetic field of permanent-magnet pieces by housing and workpiece to be added formation magnetic loop, meanwhile,
Electromagnetic field also can only be by workpiece to be added, i.e. permanent-magnet pieces, coil block in workpiece to be added by limitation
Magnetic loop is produced between housing；Under non-suction state, i.e., sticking is not to be processed for electric permanent magnet
Under the off working state of part, due to that would generally be deposited between the workbench of workpiece to be added and electric permanent magnet
In the air gap, and because the magnetic conductivity of air is very low, then it can stop to electric permanent magnetism Tie Tong
Electricity, electromagnetic field disappears, and the magnetic lines of force of permanent-magnet pieces can select magnetic loop more unobstructed enclosure interior
Pass through, loss of excitation state is shown as to hull outside, and if between workbench and workpiece to be added
, can also be reverse with above-mentioned direction initialization by being passed through to electric permanent magnet when the air gap is smaller
Electric current, makes the in opposite direction of electromagnetic field and permanent magnetic field, promotes the magnetic line of force of permanent magnetic field out of housing
Portion passes through, and loss of excitation state is shown as to hull outside.
It can be seen that, such a electric permanent magnet is passed through the electric current of coil block by changing, you can realize work
Make the superposition or disappearance of magnetic field intensity on platform, easy to operate, control is simple, automaticity compared with
It is high；In addition, carrying out suction, unit area magnetic force with the magnetic field that is superimposed of permanent magnetic field by electromagnetic field
Larger, operational efficiency is higher, meanwhile, caloric value is smaller, so that fault rate is relatively low, it is persistently resistance to
With.
