Description
Technical Field
The utility model relates to an electromagnetic clamp relates to an electromagnetic chuck structure.
Background
The electromagnetic chuck is a fixture which utilizes the electromagnetic principle to make the chuck body generate suction force to suck a workpiece after the electromagnetic coil is electrified and the magnetic force disappears after the coil is powered off to realize demagnetization and conveniently take down the workpiece. The electromagnetic chuck is generally composed of an iron core, a coil, a panel, a bracket and the like, wherein an electromagnet composed of the coil and the iron core is a main part of the electromagnetic chuck. General electromagnet is single electromagnet, and the in-process of absorbing the part can't accurate positioning relatively, can't confirm the relative position at part and electromagnet center promptly, leads to the part to inhale askewly easily, consequently can't be applicable to the occasion that positioning accuracy requires height. Therefore, it is desirable to design an electromagnet device that can stably suck a part and ensure the precision of the sucking position.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an electromagnetic chuck structure, in view of the drawback of single electromagnetic chuck, improve the part and absorb stability and position accuracy nature.
In order to achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides an electromagnetic chuck structure, its includes unable adjustment base and installs the magnetism body of inhaling on unable adjustment base, and the magnetism body of inhaling comprises two electromagnets that arrange side by side and polarity is opposite, forms the magnetic line of force between the iron core of two electromagnets, and when sucking the work piece, the central line of work piece and the coincidence of the magnetic line of force central line that two electromagnets constitute.

In particular, different magnetic bodies independently control the power on and off.
To sum up, the beneficial effects of the utility model are that, compared with the prior art, the electromagnetic chuck structure adopts two electromagnetism opposite polarity to adsorb the work piece for work piece central point puts only probably to be located the central line of two electromagnets, avoids the work piece to inhale askew condition and takes place, and is more stable, is applicable to getting of high position degree requirement and puts the material operating mode.
Drawings
Fig. 1 is a schematic structural diagram of an electromagnetic chuck structure provided in an embodiment of the present invention;
fig. 2 is a schematic diagram illustrating an arrangement of a plurality of magnetic attraction bodies in an electromagnetic chuck structure according to an embodiment of the present invention.
Detailed Description
The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.
Referring to fig. 1 and 2, the present embodiment provides an electromagnetic chuck structure, which includes a fixing base 1 and a magnetic attraction body 2 installed on the fixing base 1, wherein the magnetic attraction body 2 is composed of two electromagnets 3 arranged in parallel and having opposite polarities, and one iron core can be S-pole and the other iron core can be N-pole by applying opposite potentials to the two electromagnets 3.
Wherein, magnetic lines of force are formed between the iron cores of the two electromagnets 3. For a single electromagnet, the iron core of the electromagnet and the magnetic loop of the shell are annular, so that when the electromagnet adsorbs a workpiece, two conditions can occur, namely the center of the workpiece coincides with the center of the sucker, the unilateral center of the workpiece coincides with the center of the sucker, the first condition is a normal adsorption condition, and the second condition is an oblique adsorption condition.
The adoption of the double electromagnets can ensure that the workpiece 4 is sucked in a simple SN environment presenting a straight line, so that only one adsorption position is arranged in the magnetic circuit, namely, the central line of the workpiece 4 is superposed with the central line of the magnetic force line formed by the two electromagnets 3, and the workpiece 4 can be sucked relatively stably.
The housings of the two electromagnets 3 are preferably arranged next to each other, and the size of the workpiece 4 is preferably also close to the diameter of the electromagnets 3, otherwise the distance must also be smaller than the diameter of the workpiece 4.
The iron core of the electromagnet 3 is preferably made of low remanence material to avoid influencing the demagnetization of the workpiece 4, and if more remanence material is used, a non-magnetic sheet 5 such as a stainless steel sheet, a plastic sheet and the like can be arranged on the adsorption surface of the magnetic suction body 2; or a non-magnetic conductive coating such as chrome plating can be arranged on the adsorption surface.
On this basis, it is expected that a plurality of magnetic attraction bodies 2 are arranged on the fixed base 1, and the magnetic attraction bodies 2 are arranged in an array at intervals, and particularly, the polarities of the electromagnets on the same side are the same. The plurality of magnetic suction bodies 2 can be controlled independently or controlled in a combined mode to adapt to different occasions.
In conclusion, the electromagnetic chuck structure adopts double electromagnets with opposite polarities to adsorb the workpiece, so that the central position of the workpiece can only be located on the central lines of the two electromagnets, the phenomenon that the workpiece is askew to be adsorbed is avoided, the electromagnetic chuck structure is more stable, and the electromagnetic chuck structure is suitable for the material taking and placing working condition with high position degree requirement.
The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
