[0011] It comprises a plurality of jig blocks that are magnetically attached to the base plate and support and fix a workpiece.

[0013] And the above jig block is a square block and is characterized by having a through hole formed in the center. Effects of the invention

[0015] The magnetic jig according to the present invention is a product in which a jig block is magnetically coupled to a base plate, allowing a workpiece to be supported and fixed simply and quickly by arranging the jig block on the base plate according to the shape of the workpiece and magnetically coupling it. Accordingly, it can be used for various types of workpieces with different shapes, and the setting of the jig block for supporting and fixing the workpiece is performed simply and quickly, making it an invention highly useful for industrial development. Brief explanation of the drawing

[0017] FIG. 1 is a perspective view illustrating a magnetic jig according to an example of the present invention. FIG. 2 is a perspective view illustrating an example in which a workpiece in FIG. 1 is supported and fixed. Specific details for implementing the invention

[0018] Hereinafter, a magnetic jig according to the present invention will be described in more detail with reference to the drawings.

[0020] Before describing the magnetic jig according to the present invention in more detail,

[0021] The present invention is capable of various modifications and may take various forms, and embodiments (aspects or examples) are to be described in detail in the text. However, this is not intended to limit the present invention to the specific disclosed forms, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0022] In each drawing, identical reference numerals, particularly those with identical tens and ones digits, or identical tens, ones, and alphabets, represent components having the same or similar functions; unless otherwise specified, the components referred to by each reference numeral in the drawing should be understood as components conforming to these criteria.

[0023] In addition, in each drawing, the components are depicted with exaggerated sizes or thicknesses, or simplified, for the sake of ease of understanding; however, the scope of protection of the present invention should not be interpreted as being limited by this.

[0024] The terms used in this specification are used merely to describe specific embodiments (aspects or examples) and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, terms such as “comprising” or “consisting of” are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0025] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.

[0027] As shown in the drawing, the magnetic jig according to the present invention is composed of a base plate (10) and a plurality of jig blocks (20).

[0029] The above base plate (10) has an upper surface that is flat and generates an electromagnetic force to which power is supplied.

[0030] A workpiece (1) to be processed is placed on the base plate (10).

[0031] Above the base plate (10), a processing machine (3) for processing a workpiece (1) and an air nozzle (5) for removing processing debris, such as chips generated during processing of the workpiece (1), by blowing it with high-pressure air are provided.

[0033] The above jig block (20) is magnetically coupled to the base plate (10) and supports and fixes the workpiece (1) placed on the base plate (10).

[0034] The above jig block (20) is made of metal or a permanent magnet that is magnetically coupled to the base plate (10) where electromagnetic force is generated. In addition to metal or a permanent magnet, the jig block (20) may also use an object that generates electromagnetic force when power is supplied.

[0035] The above jig block (20) can be in the shape of a square block as shown in the drawing, and can also be a circular block, a triangular block, a pentagonal block, etc. Square blocks are preferred because they are easy to align and arrange on the base plate (10) and can be supported by each other.

[0036] Generally, the jig blocks (20) are arranged in a single layer on the base plate (10) to support and fix the workpiece (1), but depending on the size or shape of the workpiece (1), the jig blocks (20) may be stacked to support and fix the workpiece (1). A through hole (21) is formed in the center of the jig block (20) so that the jig blocks (20) can be stacked in the correct position. When a pin is inserted into the through hole (21), it is easy to stack the jig blocks (20) in the correct position.

[0038] The process of setting the jig according to the present invention for processing the workpiece (1) is as follows.

[0039] First, place the workpiece (1) on the base plate (10).

[0040] Next, the jig blocks (20) are placed on the base plate (10) to support the sides of the workpiece (1).

[0041] Next, power is supplied to the base plate (10) to generate electromagnetic force, thereby magnetically coupling the jig block (20) to the base plate (10), and thus fixing the workpiece (1).

[0043] In describing the present invention above, a magnetic jig having a specific shape and structure has been described with reference to the attached drawings; however, the present invention is capable of various modifications and changes by those skilled in the art, and such modifications and changes should be interpreted as falling within the scope of protection of the present invention.
