Abstract

The utility model provides a permanent magnetic chuck. The traditional permanent magnetic chuck has the problems of weak compressive force of magnetic line force, easy diffusion and magnet leakage. The permanent magnetic chuck includes a panel, a pole shank plate and a base plate bracket. The pole shank plate includes a plurality of magnetizers, a plurality of fixed magnets and a plurality of flexible magnets. The fixed magnets are fixed on the two corresponding lateral sides of the magnetizers. The flexible magnets are equipped on the other two corresponding lateral sides of the magnetizers and can move a step. The flexible magnets and the fixed magnets have the same polarity towards the same magnetizers. The utility model can utilize the property of repulsion of the same polar, compression and collective magnetic force of magnets, in order to obtain the permanent chuck with stronger attraction.

Description

A kind of permanent magnetic chuck
Technical field
The utility model relates to a kind of magnetic suction disc, relates in particular to a kind of permanent magnetic chuck.
Background technology
Permanent magnetic chuck is the common tool of Metal Cutting Machine Tool, when Metal Cutting Machine Tool is worked, as sticking, fastening, location workpiece.
Existing permanent magnetic chuck is generally by panel, pole piece plate with make the pole piece plate form (not shown) with respect to the travel mechanism of panel move left and right.For permanent magnetic chuck, it must form the loop to the magnetic energy that magnetic material produces by magnetic conductor, produces magnetic attraction, the sticking workpiece.In traditional permanent magnetic chuck, the method for employing is magnetic material to be narrowed down to small size from large tracts of land compress flux density, thereby obtains stronger magnetic field.But, exist compression stress not strong, diffusion and shortcoming such as leakage field is serious.
The utility model content
Therefore, the purpose of this utility model is to provide a kind of permanent magnetic chuck that can obtain than high-intensity magnetic field.
Permanent magnetic chuck of the present utility model utilizes the characteristic of the homopolar-repulsion of magnet itself, compression and gathering magnetic force, thus obtain the stronger permanent magnetic chuck of suction.
Therefore, the permanent magnetic chuck that the utility model provides comprises panel, pole piece plate and mount holder, it is characterized in that, described pole piece plate comprises polylith magnetic conductor, polylith fixed magnets and polylith movable magnet, described fixed magnets is fixed on two relative sides of described magnetic conductor, described movable magnet is arranged on other two relative sides of described magnetic conductor, and a removable pitch; Described movable magnet is identical towards the polarity of same described magnetic conductor with described fixed magnets.
According to an aspect of the present utility model, described magnetic conductor is cube shaped, and the polylith magnetic conductor is arranged into array format, leaves the space between the adjacent described magnetic conductor.
According to another aspect of the present utility model, fill impervious material in the space between described magnetic conductor.
According to another aspect of the present utility model, described movable magnet and described fixed magnets are close to described magnetic conductor.
According to another aspect of the present utility model, described mount holder is made by non-magnet material.
According to another aspect of the present utility model, described panel is made by permeability magnetic material.
Description of drawings
Operation principle of the present utility model, feature and other advantage will become more obvious by following detailed.In the accompanying drawing:
Fig. 1 is the structural representation of permanent magnetic chuck of the present utility model;
Fig. 2 and Fig. 3 are respectively the schematic diagram of permanent magnetic chuck of the present utility model when being in sticking and release conditions, are used to illustrate the operation principle of permanent magnetic chuck.
The specific embodiment
As shown in Figure 1, permanent magnetic chuck of the present utility model comprises three parts: panel 4, pole piece plate 6 and mount holder 5.Pole piece plate 6 be positioned at mount holder 5 above, panel 4 then be positioned at pole piece plate 6 above.Be pole piece plate 6 with traditional permanent-magnet suction cup structure difference.
See also Fig. 1, pole piece plate 6 is made up of polylith magnetic conductor 1, polylith fixed magnets 2 and polylith movable magnet 3.Magnetic conductor 1 is fixed on the mount holder 5, and, all reserve certain space between each magnetic conductor 1.Fixed magnets 2 is fixed on two relative sides of magnetic conductor 1, and is close to it.Movable magnet 3 is arranged on other two relative sides of magnetic conductor 1, also be close to it, but this movable magnet 3 is transportable, and (not shown, this travel mechanism and traditional travel mechanism are similar in auxiliary travel mechanism, therefore, be not described in detail in this) effect under, this movable magnet 3 can move a pitch, promptly, the position of a magnetic conductor 1, the position that movable magnet 3 can be moved a magnetic conductor.
In preferred embodiment, magnetic conductor 1 can adopt cubical form, and polylith magnetic conductor 1 can be arranged into array format (only show the part of permanent magnetic chuck among Fig. 1, so-called array format can referring to Fig. 2 and shown in Figure 3).Selecting for use of material, panel 4 and magnetic conductor 1 can adopt permeability magnetic materials such as mild steel; Fixed magnets 2 and movable magnet 3 can adopt permanent-magnet materials such as neodymium iron boron; Mount holder 5 can adopt non-magnet material.In the space between adjacent cube magnetic conductor 1, can fill the material of water-impervious, certainly, this impervious material should adopt the material of non-magnetic conduction.
The operation principle of permanent magnetic chuck of the present utility model is described below in conjunction with Fig. 2 and Fig. 3.The schematic diagram that shown in Figure 2 is when permanent magnetic chuck is in the sticking state; The schematic diagram that shown in Figure 3 is when permanent magnetic chuck is in release conditions.Clear with diagram for convenience of explanation among Fig. 2 and Fig. 3, all omitted panel and mount holder among the figure, only show the structure of pole piece plate 6.
As shown in Figure 1, when being in the sticking state, fixed magnets 2 is identical towards the polarity of same magnetic conductor 1 with movable magnet 3.Like this, the magnetic line of force that each magnet sends also is subjected to the repulsion (compression) of the magnetic line of force of adjacent or relative same polarity except the guiding that is subjected to magnetic conductor, and the magnetic line of force can not or be escaped to the horizontal direction diffusion, is forced to focus on the above-below direction of magnetic conductor.Owing to be positioned at the mount holder 5 for being made by non-magnet material below the pole piece plate 6, therefore, magnetic energy all focuses on the panel 4 that permeability magnetic material makes, thereby can make panel 4 live workpiece by stickings.
After movable magnet 3 being moved a pitch by travel mechanism (not shown), the polarity of movable magnet 3 and fixed magnets 2 distributes as shown in Figure 3, promptly, polarity towards the movable magnet 3 of same magnetic conductor 1 and fixed magnets 2 is just in time opposite, at this moment, the magnetic line of force of movable magnet 3 and fixed magnets 2 is at magnetic conductor 3 internal short-circuits.Magnetic conductor does not manifest residual magnetic induction at above-below direction, thereby the no suction in panel top, has realized the closed condition of permanent magnetic chuck.
