Description

Jig for metal working}

The present invention relates to a jig for metal processing.

In general, a machining center is metal processing equipment used for processing metal parts, including mold manufacturing.

Machining centers have the feature of automatically exchanging and processing tools using a change arm in a tool storage area called a tool magazine.

In addition to 3-axis machining (horizontal, vertical, and height), machining centers are recently capable of 5-axis machining with the addition of 2 axes of rotational movement, making it possible to process complex shapes.

A machining center like this is composed of a base part called a bed, a saddle that moves on the bed, a table mounted on the saddle to install the processing material, a column installed perpendicular to the bed, and a spindle head that mounts a bite. .

Meanwhile, in order to process a workpiece using a machining center, an operator must fix the workpiece on a table using a plurality of jigs. At this time, the plurality of jigs are composed of jack support members that support the bottom surface of the workpiece and clamps that press the top surface of the workpiece.

More specifically, in the past, a worker installed jack support members on a table, placed a workpiece on the upper surface of the jack support members, and installed clamps on the table along the circumference of the workpiece to support the workpiece.

However, in the past, as described above, the operator had to individually install the jack support members and clamps on the table sequentially, making the installation work difficult, and fixing the workpiece took a long time, delaying the overall work. Of course, there was a problem that productivity was reduced due to this.

In addition, conventionally, as workers manually manipulate the jack support member and clamp to adjust the pressing position, the workpiece cannot be supported with uniform pressure, and as a result, the workpiece cannot be supported stably, causing the workpiece to fall from the jig during processing. There was a problem with it coming off.

In addition, as the conventional jig described above is configured to support only the upper and lower surfaces of the workpiece, there is a problem in that the workpiece flows due to an external force applied to the workpiece in the horizontal direction during side machining of the workpiece, resulting in machining defects.
