The present invention relates to a jig, and more specifically, to support a variety of workpieces of various shapes with a single jig without making a dedicated jig for each work piece to be able to work, of course, each other The present invention relates to a jig configured to accurately set a coordinate corresponding to a machining position of a work piece on a jig even when supporting a plurality of work pieces at the same time and performing continuous machining work.

Generally, jigs are used to hold or fix a product (hereinafter referred to as a workpiece) for continuous mass operation on a workbench of a processing and forming apparatus, and mainly to stably support a workpiece. For this purpose, a dedicated jig having a shape corresponding to the shape of each work piece is manufactured and used.

Accordingly, most of the conventional jig has a non-economic problem that can not be reused jig used previously when the shape and specification of the workpiece is changed to be re-made for a new workpiece.

For example, a jig used to print an image or text on the outer surface of a workpiece or marking using a laser device may produce a smaller quantity of various types of workpieces than a large amount of one type of workpiece. Often work with marking.

As a result, the production cost of the dedicated jig for each model produced for the automated marking work is higher than the marking work cost for each work piece, thereby increasing the manufacturing cost of the product, resulting in an uneconomical factor. It was.

In addition, in the conventional case, since the shape of the marking work has many shapes having a three-dimensional appearance in many cases, a three-dimensional molding process for producing a shape for stably fixing the jig is involved.

Accordingly, there is a problem that a lot of difficulties are involved in the production of the dedicated jig due to problems such as a rise in the manufacturing cost of the product due to the increase in the cost of marking work, to solve this problem, various types of workpieces can be solved regardless of the three-dimensional shape of the workpiece. It is necessary to develop a jig that can be stably supported and reused semi-permanently.

Recently, marking printers and laser engravers, which are mainly used for marking work, are automation devices used in connection with a computer, and have a feature of continuously marking marking images displayed on a computer screen on a plurality of product surfaces. As a result, several workpieces are placed on a dedicated jig at the same time, and the coordinates of the marking positions are set on the workpiece surface for continuous marking.

However, in the related art, since there is no additional configuration for setting the same reference point as the marking reference point on the computer drawing on the jig, the operator sets the reference coordinates on the jig arbitrarily to mark the work surface, thereby marking the work. As a result of frequent occurrence of defects, a jig capable of setting an accurate marking position is urgently needed.

The present invention has been devised to solve the above-mentioned problems, and does not produce a dedicated jig for each work piece. The supporting surface of the jig is configured to be freely deformed and stably supported in a fluid manner corresponding to the outer shape of the workpiece so that the work is possible to provide a semi-permanently reusable jig.

When not generated) to generate a magnetic force is a guide pin 60 of the metal material is attached by the magnetic force of the magnetization plate 110 can be maintained in a completely fixed state to support the workpiece (W) stably.

In addition, the magnetization plate 110, as in the above embodiment, even if the paraffin (P) is forcibly cooled, the working environment that does not harden to a solid, that is, the internal temperature of the workplace is high, the paraffin (P) is fixed to the guide pin 60 By using the magnetic force of the magnetization plate 110 in the working environment that is not doing it is to be used to fix the alignment state.

For example, the operation and effects of the marking operation using the jig 100 according to the present invention configured as described above will be described below in detail with reference to FIGS. 4 to 7.

First, looking at the initial alignment process of the guide pin 60, since the paraffin (P) charged inside the jig body 10 is a solid state at room temperature, the heater (11) is heated to melt the paraffin (P) in a liquid state and then the guide pin After making the state that 60 can flow, press the plurality of guide pins 60 to the top plate top surface.

Next, the partition plate disposed between the guide pins 60 is moved by using the guide piece 82 in the X and Y directions to partition an area in which the work W is to be placed. After the measurement, the partition piece 80 may be moved to the measured position.

Then, as shown in FIG. 4, the partition piece 80 displays the reference line in the X and Y directions in which the position of the workpiece W can be set.

These reference points can be set to be the same as the automatic marking coordinates by the computer, so simply replace the workpiece (W) by simply placing it close to the corner of the workpiece (W) section 80 during the actual marking operation. Accurate and continuous marking can be done.

Next, the operator puts the initial setting plate 70 on the work table (W), as shown in FIG. 5 and then lifts the entire jig 100 and presses the initial setting plate 70 on the plurality of guide pins 60. The upper surface of the initial setting plate 70 in contact with the top plate 50 is moved upward, so that the entire number of the guide pins 60 can be easily aligned horizontally in a batch.

At this time, since the paraffin (P) is a natural cooling process, the guide pin 60 is horizontally aligned by moving upwards without difficulty.

Next, when the initial setting plate 70 is separated from the jig 100 main body, the naturally cooled and slightly hardened paraffin (P) is in a state of holding the guide pin 60 so as not to go down to maintain a horizontal alignment state.

Next, the operator is holding the workpiece (W) while pressing the workpiece (W) in close contact with the edge of the partition piece 80 as shown in Figure 6, the guide pin pressed on the outer surface of the workpiece (W) ( 60 is pushed down by the pressing force to form the arrangement state of the guide pin 60 to support the workpiece (W) appearance.

Next, after placing the workpiece (W) in the area divided by the partition piece 80 as described above, each workpiece (W) is arranged in a batch by using the top setting plate (90).

At this time, the work W positioned below the top setting plate 90 is supported by the guide pin 60, and thus is pressed on the bottom of the top setting plate 90 so that the work W and the guide pin 60 are held down. ) Will go down together.

When pressing the upper set plate 90 continuously, the lower surfaces of both ends of the upper set plate 90 are caught on the upper surface of the jig body 10 so that the work W is supported by the guide pin 60. At the same time, the workpieces W pressed by the top setting plate 90 are arranged in a batch so that the upper surface thereof is maintained in a horizontal state.

The work alignment of the workpiece W by the upper setting plate 90 can not only increase the efficiency of the automatic marking work but also make the marking work at the same position as that set on the computer, thereby improving the reliability of the marking work. It is a very important factor to keep it consistent so that no marking defects occur.

When the initial setting work of the workpiece (W) is made as described above, the workpiece (W) is supported and wrapped by the guide pin (60) around its entirety and bottom surface, and thus a series of marking operations are completed. Even when replacing with water (W), you only need to put the workpiece (W) in the position, it does not need to set again after the initial setting.

In addition, even in the case where different marking operations are performed on several kinds of workpieces W having different designs and external sizes, the jig 100 according to the present invention is divided by the partition pieces 80 as described above. Marking work can be done continuously by placing workpieces (W) with different designs in different areas at the same time.

On the other hand, after the setting operation as described above to connect the exhaust fan (not shown) to the exhaust duct 14 as a process of hardening the paraffin (P) in order to maintain the alignment state of the guide pin 60 jig body 10 When the warm air is discharged to the outside, the cooling speed of the paraffin (P) is accelerated to quickly become a solid state.

When the paraffin (P) is in a completely solid state is to hold the guide pin 60 more securely it is possible to continue using the jig 100 initially set.

In addition, to more reliably fix the alignment state of the guide pin 60, the magnetization plate 110 provided between the silicon pad 30 and the base 20 may be operated.

When the magnetic circuit generating device is connected to the magnetizing plate 110, a strong magnetic force is generated, so that the plurality of guide pins 60 inserted into the pin holes 111 of the magnetizing plate 110 are magnetized by the magnetic plate 110. ), It is securely attached.

Therefore, the guide pin 60 is fixed to the guide pin 60 firmly without flowing up and down, unless artificially or externally impacted.

 In the above, the description of the embodiment for the jig according to the present invention is merely for the purpose of illustration, the present invention is not limited to this, of course, can be variously modified within the claims.

As described above, the jig according to the present invention can freely deform the guide pins in correspondence with various shapes of workpieces, thereby supporting various workpieces at the same time, making it convenient and accurate as well as continuous automatic machining.
