The X-axis holder 10 and the Y-axis holder 12 are supported by a digital display unit 19 on the gauge body, and have a combination of two plates extending alongside the gauge body, whereby the movement of the holder is intact. It can be expressed through the digital display unit 19.

The tip of the holder in direct contact with the workpiece has a stepped shape, which serves as a reference plane for positioning the workpiece.

As the die means, a die block 15 in the form of a square plate is provided.

The die block 15 is a kind of die which is combined with a punch of a tool while supporting a work, and four forming holes 14 having different shapes are formed at four symmetrical positions at corners. When the setting position of the block 15 is turned by 90 °, all four forming holes 14 can be effectively used.

This die block 15 is mounted and used in a structure that is inserted and seated in a predetermined rectangular space created by the setting block 16 on the base plate 17, and can be easily removed after use.

The setting means is provided with a base plate 17 comprising a setting block 16.

The base plate 17 is a base for installation of the above holder and guide means and die means.

Both sides of the base plate 17 are provided with slots 21 on which one side to which bolts and the like can be fastened when being fixed to a work table or a surface plate and moved to the corresponding facilities depending on the type of work on the workpiece. It can be easily fixed and used or can be easily separated.

The setting block 16 has an integral wall structure that forms a rectangular space having an open top at the center of the base plate 17, and each supporting surface 20 having a constant height inside each of four walls. ), The die block 15 can be set on it.

The setting block 16 has a vertical groove 22 formed in a circular shape at four corners of the wall and a lower bolt seat 23 at the bottom thereof. The die block 15 is inserted into the setting block 16. When the bolt is fastened to the bolt seating surface 23 through the die block 15 in the state, the die block 15 can be set completely, and the vertical groove 22 at this time is the square die block 15. When assembled or separated in the setting block 16, it serves to smooth the assembly or separation by eliminating the interference of the corner portion.

When the die block 15 is inserted into the setting block 16 and seated on the support surface 20, the upper surface of each block can constitute the same flat surface, thereby moving the workpiece along the block surface. The interference can be completely eliminated, and the bottom surface of the X-axis holder 10 and the Y-axis holder 12, which are disposed in close proximity to them, are also made of the same surface as the block surface above so that the slide contact progression of the holder can be smoothly performed. do.

Each of the above gauge blocks 18 is disposed and fixed one by one at a position close to the outer two surfaces of the setting block 16, and the X-axis holder 10 and the X-axis gauge 11 and the holder 12 of the Y-axis. And the Y-axis gauge 13 can be extended in each direction by using the respective gauge block 18.

Figure 3 is a perspective view showing one example of applying the workpiece jig of the present invention to the punching operation of the press equipment.

As shown in FIG. 3, the whole work jig is set on the work bench 120 of the press installation 110 provided with the punch 100 as a tool for hole making using the base plate 17. As shown in FIG.

The selected forming hole 14 of the die block 15 in the work piece jig in which the setting is completed coincides with the punch 100 mounted on the press equipment 110 on a vertical cutting line, and the work piece 130 is X Punching operation can be performed by operating the handle 140 while the two surfaces are supported by the shaft holder 10 and the Y-axis holder 12 as a reference plane and fixed by a separate clamping tool (not shown). Will be.

The workpiece jig of the present invention can be widely applied to a variety of facilities, such as a drilling machine, a milling machine, as well as a press facility as the above application example, by a simple operation of moving and setting the entire work jig, and in particular, a die block 15 By turning the setting of) by 90 ° and selecting only the corresponding molding hole 14, at least four molding operations can be performed with only one die block 15, thereby increasing the overall workability related to the workpiece machining. Improvements in overall productivity can also be expected.

As shown in FIG. 4A, when machining holes at regular intervals in the X-axis direction on the workpiece 130, the X-axis holder 10 and the X-axis are set with the Y-axis holder 12 in a fixed state as a reference plane. Holes are sequentially processed while setting the machining position of the workpiece 130 using the gauge 11.

At this time, the pitch shift corresponding to the machining position of each hole of the workpiece 130 is displayed numerically on the digital display unit 19 of the X-axis gauge 11, so that the operator can visually confirm this, so that the machining position can be set Therefore, the hole processing for the workpiece 130 can be made to the correct pitch.

That is, since the work is performed while determining the pitch movement distance of the workpiece with the fine scale of the gauge, it is possible to increase the precision of machining on the workpiece.

As shown in FIG. 4B, a case in which holes at regular intervals are machined in the Y-axis direction on the workpiece 130 is shown. In this case, the fixed X-axis holder 10 is referred to as a reference plane, and the Y-axis Hole setting may be performed while setting the machining position of the workpiece 130 using the holder 12 and the Y-axis gauge 13.

On the other hand, in the same process as above, the Y-axis holder 12 as a reference plane may be used to process holes at regular intervals using the X-axis holder 10 and the X-axis gauge 11, the holder of the X, Y axis The punching operation of the workpiece may be performed at the position where the user sets the machining position of the workpiece by interacting the (10, 12) and the gauges (11, 13).

As described above, the present invention can precisely shift the machining position of the workpiece in the X-axis and Y-axis directions, and if the setting position is changed, the workpiece jig includes a die block capable of performing various molding operations. By providing a single jig, it is possible to carry out various molding operations, and thus, there is an advantage of improving workability and productivity, and most of all, it is possible to facilitate accurate positioning of the workpiece, so that overall work related to workpiece machining This is simple, and in particular, there is an advantage that can increase the precision of machining on the workpiece.
