In the rotation of X-axis, Y-axis similarly.It is more convenient during in order to realize positioning, the magnetic means in the X-axis and Y-axis of workpiece is existed
Cross on its extended line, so as to continuously be arranged in the multiple magnetic means of top view, and form L-type.
The structure type of magnetic means can have a variety of, such as use permanent magnet, electromagnet etc..
Such as Fig. 5, in the alternative of the present embodiment, magnetic means includes shell, be provided with shell coil 3, iron core and
Pre exciting switch 1, coil 3 are wrapped in the side of iron core, and pre exciting switch 1 and coil 3 are electrically connected.After pre exciting switch 1 is opened, coil
Access direct current in 3.Since coil 3 is wrapped in the side of iron core, so as to form magnetic pole 5.Access direct current in coil 3
Afterwards, iron core is magnetized, and magnetic means produces the magnetic force that can adsorb workpiece at this time.
On the basis of above-described embodiment, more sub- cavitys further, in shell have been arranged side by side, in the sub- cavity
It is both provided with a coil 3 and an iron core.More sub- cavitys are arranged side by side in shell, in every sub- cavity
A magnetic pole is respectively provided with, each magnetic pole includes coil and iron core.
Since magnetic induction line is produced between workpiece and magnetic pole, magnetic line of force generation can be reduced by reducing the size of each magnetic pole
When collision to workpiece, in order to ensure enough adsorption capacities, the area of total magnetic pole is sufficiently large, therefore in the present embodiment,
Several sub- cavitys are further separated out in each shell, are respectively provided with a magnetic pole in every sub- cavity, each magnetic pole wraps
Coil and iron core are included, magnetic means is produced magnetic field evenly, so as to generate adsorption capacity evenly when being powered.
Two sub- cavitys are arranged side by side in the alternative of the present embodiment, in shell.
In the alternative of the present embodiment, the upside of bottom plate 7 is provided with multiple magnetic means, has in each magnetic means
Multiple magnetic poles 5, the coil 3 of all magnetic poles 5 are all connected on pre exciting switch 1.
On the basis of above-described embodiment, further, shell is divided into medial surface and lateral surface, and adsorbing plane is located at inner side
Face, lateral surface are the face opposite with medial surface, are provided with opening on lateral surface, opening is provided with magnetic pole lid 4.
In the alternative of the present embodiment, the distance between magnetic pole 5 and medial surface that coil 3 and iron core are formed are more than line
The magnetic pole and the distance of lateral surface that circle 3 and iron core are formed.Inventor has found, if the excessive table that may result in workpiece of magnetic force
Surface damage, and workpiece surface can be reduced by increasing the distance between magnetic pole and adsorbing plane and damaged.
Opening is provided with outer side face, opening is provided with magnetic pole lid 4.Magnetic pole can be taken out out of housing at this time.
Convenient maintenance, replace magnetic pole.
Magnetic pole lid 4 can be connected on housing by way of being spirally connected.In the alternative of the present embodiment, the magnetic pole lid
4 and the shell clamping.When the overall dimensions of magnetic means are less, clamping is more convenient.
On the basis of above-described embodiment, further, there is adhesive between the iron core and the coil 3.Due to work
Part may be cooled down in cutting using to substantial amounts of coolant, and adhesive can prevent from entering liquid in magnetic pole.This reality
In the alternative for applying example, the adhesive is polyurethane.
The present embodiment also provides a kind of destressing magnetic suction disc, to mitigate influence of the cutting stress to workpiece.
It is the poor rigidity of the part of deep chamber class, yielding, at the same ensure its processing quality and reduce process work step, improve plus
Work efficiency rate, is solving the problems, such as always for this area.The destressing magnetic suction disc of the present embodiment, in the dress of the part of deep chamber class
Accompany more preferable effect.
A kind of destressing magnetic suction disc, including above-mentioned magnetic suction disc, the bottom plate 7 include workpiece rest area 9, the work
Multiple through holes are provided with part rest area 9.
The poor rigidity of the part of deep chamber class, in process because being subject to cutting stress, clamping force and cutting heat and residual

Disk, and the region for being used to place workpiece on its bottom plate 7 is arranged to workpiece rest area 9, is provided with workpiece rest area 9 multiple logical
Hole.
The effect of destressing magnetic suction disc is：Through hole in workpiece rest area 9 reserves certain sky for local elastic deformation
Between, this space make it that the position of elastic deformation is controllable., after it has been formed can be completely extensive again because being deformed into elastic deformation
It is multiple.In this way, clamped position of the part of deep chamber class in clamping would not occur local elastic deformation again, so as to will not cause
The small translation and rotation of workpiece, so as to fulfill the accurate positionin in processing.Therefore destressing magnetic suction disc avoids cutting
Influence of the stress to workpiece.
On the basis of above-described embodiment, further, the sectional area all same of each through hole.Certainly, further
, the shape and size of each through hole are identical.Through hole functions as described above, therefore the area of each through hole is the same with regard to energy
Enough ensure more uniform control deflection.On the basis of above-described embodiment, further, multiple through-hole array are set.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, those of ordinary skill in the art should
Understand：It can still modify the technical solution described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical solution of type.
