Description

Variable Jig Device {VARIABLE JIG APPARATUS}

The present invention relates to a variable jig device, and more particularly, to a variable jig device used when processing a hole having a predetermined depth opposite both sides of a workpiece.

In general, a jig is a device that is fixed to a worktable for processing a workpiece or facilitates the operation of a cutting tool. In other words, a jig is called a jig tool. Such a jig is used in various processing processes for a workpiece, such as cutting.

Here, the jig is variously used for cutting a workpiece for automobile manufacturing and for cutting a workpiece for aircraft manufacturing. For example, a jig used for aircraft manufacturing is typically used in the aircraft industry to support a workpiece having a plurality of holes being cut. As an embodiment, when cutting a plurality of holes facing both sides in the aircraft industry, a jig is used to support a workpiece to cut a hole on the other side within a hole cut on one side.

Meanwhile, in the above-described cutting process of a plurality of holes facing both sides in the aircraft industry, after machining a plurality of holes on one side, one side of the workpiece having a plurality of holes is supported on a worktable, and a plurality of holes is cut on the other side. To form. At this time, when forming a hole on the other side of the work by cutting, a jig for supporting the work is used between the hole on one side and the worktable.

However, the conventional jig is disposed between the hole and the work table corresponding to a certain depth or height of the hole. These conventional jigs require a corresponding jig whenever the depth or height of a hole changes, so the time required for the process increases, and as a plurality of jigs corresponding to the depth of each hole are required, the cost is also costly. There arises a problem of increasing the value.
