BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machining jig for a machine tool such as a laser machining machine, and more particularly to a machining jig used for machining an extremely thin plate material.

[0002]

2. Description of the Related Art Conventionally, in laser processing, for example,
When processing an ultra-thin plate of 0.5 mm or less, the so-called raw material is weak and easily bends, so it is placed and stuck on corrugated board and both processed (co-cutting), sawtooth sword mountain It is customary to reduce the pitch and change the shape.

[0003]

However, in the above-mentioned conventional example, in the case where the plate material to be processed is placed / pasted on the corrugated board and both processings (co-cutting) are performed,
There are problems such as corrugated cardboard igniting and causing a fire,
Further, if the pitch of the saw-toothed swords is narrowed or the shape is changed, there are inconvenient problems such as economical aspects and complicated handling / troublesomeness in handling.

The present invention has been made in view of the above circumstances, and it is possible to accurately support and hold a work piece (workpiece) in a flat surface, and to perform work alone, thereby avoiding the risk of fire or the like. An object of the present invention is to provide a machining jig that is safe, economical, and advantageous in handling.

Embodiments will be described below with reference to the drawings.

In FIG. 1, a plurality of plate-like stays 2 are provided upright at a predetermined pitch so as to partition and support the opening 1a having a flange 1 on the periphery thereof, and the plate-like stays provided upright are provided. The upper end of 2 is provided with a notch 2a having a predetermined depth according to the width of the opening to form a concave frame, and is formed by the opening 1a of the collar 1 and the plate stay 2. A plane formed by fitting a large number of support bodies 3 having a cylindrical chain structure in a recessed frame so as to stand upright, and a virtual plane formed by the upper surface of the support body 3 serving as a reference plane for processing. The support 3 having the cylindrical chain structure is a honeycomb core whose horizontal cross section is a hexagonal cellular aggregate.

The operation will be described with reference to the above-mentioned structure and drawings.

A jig member J of a jig for machining according to the present invention.
p is composed of a collar portion 1 and a plate-like stay 2, and the collar portion 1
A notch 2a is provided at the upper end of the plate-like stay 2 in accordance with the width dimension of the opening 1a of the collar 1 and the opening 1 of the collar 1
a and a notch 2a of the plate-like stay 2 form a concave frame. For example, as the support 3 having the tubular chain structure, a commercially available honeycomb core having a hexagonal cell-like aggregate in horizontal cross section. Select the desired size from
As shown in (b), (c), and FIGS. 4 (a), (b), the jig for machining according to the present invention is configured by being fitted so as to be dropped into the concave frame of the jig member Jp. . Since the virtual plane formed on the upper surface of the honeycomb core forming the support 3 of the jig for machining is configured to coincide with the plane formed by the pass line serving as a reference during processing, it is shown in FIG. As described above, by installing the machining jig of the present invention on the table of the processing machine, it is possible to securely support the work material (workpiece) of the ultrathin plate material without stiffness from below so that it can be accurately planar. Supporting and holding the workpiece to eliminate flapping and warpage of the workpiece during machining, as shown in FIG. 6, for example, in the case of cutting in a circular shape, machining can be performed in a stable state. Since it is not necessary to cut it together with the lower reliance member such as corrugated cardboard, it is possible to realize accurate laser processing with the work alone, avoid the risk of fire etc., it is safe,
It is possible to provide a jig for machining which is economical and advantageous in handling.

That is, by adopting a commercially available honeycomb core as a support for the work during laser processing, an increase in cost can be suppressed, and even if the upper end surface of the honeycomb core is co-processed and burned by any chance. It can be dealt with by partial replacement, which is advantageous in terms of convenience.

By the way, a support using a brush has a problem in heat resistance even though it can cope with strength, and the jig for machining which uses the honeycomb core according to the present invention is more comprehensive. It is advantageous in terms of functionality.

In the present embodiment, the case where three plate stays 2 of the jig member Jp are used and the plate stays 3 are parallel to each other has been described, but the number of plates and the parallel structure are not limited. The plurality of plate-shaped stays may be configured in a lattice shape or the like, and the configuration form is not limited.
