ある。 Conventionally, electromagnetic chucks used as workpiece holders include those that use the top surface as the main work surface and can also use the side surfaces as an auxiliary work surface, and those that work around an axis parallel to the longitudinal direction of the work surface. There is a rotary electromagnetic chuck that allows the surface to rotate.

ものである。また回転式電磁チヤツクでは作業面
の回転機構が複雑になるなどの欠点がある。 However, with conventional electromagnetic chucks in which the top surface is the main working surface and the side surfaces can be used as an auxiliary work surface, the original purpose was not to use it for work on two surfaces, and the adsorption force of the side surface is greater than that of the top surface. The adsorption force is extremely weak or the area is extremely small. Furthermore, the rotary electromagnetic chuck has drawbacks such as a complicated rotating mechanism for the work surface.
本発明な上記のような欠点を解消し、２面吸着
型電磁チヤツクを提供することを目的とする。 The object of the present invention is to eliminate the above-mentioned drawbacks and provide a two-sided adsorption type electromagnetic chuck.

ある。 In order to achieve this object, the present invention configures one end of the iron core of the electromagnet as a magnetic pole part having two mutually perpendicular working surfaces and a substantially L-shaped cross section, and this electromagnet is connected to adjacent magnetic poles on the working surface. To provide an electromagnetic chuck in which the top surface and the side surface have the same adhesion force by alternately stacking the top and side surfaces so that they have different polarities.

４の磁心部の他端には側板７が接している。 First, as shown in FIGS. 1 and 2, a case 1 having vertically elongated windows extending from the top surface to the side surfaces at equal intervals is placed on a bottom plate 2 to form an outer box for the electromagnetic chuck. Next, as shown in FIGS. 3 and 4, an upwardly directed magnetic pole is made up of a magnetic pole portion having a substantially L-shaped cross section and a magnetic core portion that is integrally connected to the magnetic pole portion, which has two working surfaces that are orthogonal to each other and have approximately equal areas. The iron cores 3 and the side magnetic pole iron cores 4 are arranged alternately so as to fit into a window opened in the case 1 via a separator 5,
Constitutes the working surface of the electromagnetic chuck. Further, an excitation coil 6 is wound around the magnetic core portions of the upward magnetic pole core 3 and the side magnetic pole core 4. Furthermore, upward magnetic pole core 3
The bottom plate 2 is in contact with the other end of the magnetic core, and the side plate 7 is in contact with the other end of the magnetic core of the lateral magnetic pole iron core 4.

なる。 Here, the excitation coil 6 is arranged so that when the magnetic pole part of the upward magnetic pole core 3 is the north pole, the magnetic pole part of the side magnetic pole core 4 becomes the south pole, and the magnetic pole part of the upward magnetic pole core 3 becomes the south pole.
When it is a pole, the wires are connected so that the magnetic pole part of the side magnetic pole iron core 4 becomes the north pole. That is, the excitation coil 6 is wired so that the polarity of the magnetic pole part of the upward magnetic pole core 3 connected via the bottom plate 2 and the magnetic pole part of the lateral magnetic pole core 4 connected via the side plate 7 are opposite to each other. do. In this way, when current is supplied from the cord 8 to the excitation coil 6, N and S poles appear alternately along the longitudinal direction of the electromagnetic chuck on the working surface of the electromagnetic chuck, and N and S poles appear on the top and side surfaces of the electromagnetic chuck. The magnetic poles are arranged symmetrically both in shape and position.

着型電磁チヤツクを提供できる。 As described above, according to the present invention, since the magnetic poles are arranged equally on the top and side surfaces of the electromagnetic chuck, it is possible to provide a two-sided adsorption type electromagnetic chuck in which the adsorption forces on the top and side surfaces are equal.
