Abstract

PURPOSE:To reduce the size of the machine by moving simultaneously a table on which a work is imposed and a beam on which a processing head is mounted in opposite directions. CONSTITUTION:An L-shaped saddle is constituted by separating the same to two parts; a stationary table 10 and a moving beam 11. The beam 11 is provided movably in a direction Y on the table 10 and a reflecting mirror 12 is disposed to the end of the beam 11. The movement of the beam 11 in the Y-axis direction is made possible simultaneously in the direction opposite from the movement of the Y-axis table 2 by the above-mentioned mechanism. The max. extent of the movement of the table 2 is therefore required just 1.5 times the length of the work 9 in the stage of setting the processing position of the work 9. The reduction in the size of the laser beam machine is made possible by the above-mentioned method.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a moving device for a processing head of a laser processing device.

[Conventional technology]

Figure 6 is a side view and a top view of a conventional laser processing device.
In the figure, (1) is the L-shaped saddle, (2) is the Y-axis table, (
3) is the beam of the saddle, (4) is the X-axis table, (5) is the processing head, (6) is the reflector, (7) is the condenser lens, (8)
) is the laser beam, and (9) is the workpiece.

The Y-axis table (2) on which the workpiece (9) is placed moves on the saddle (1) in the direction of arrow Y in the figure, while the X-axis table (4) on which the machining head (5) is attached moves. , is configured to move on the beam (3) of the saddle in the direction of arrow X in the figure. By moving the X-axis table (4) and Y-axis table (2) in the XSY direction, the processing head (5) is positioned at a predetermined position on the workpiece (9), and the laser beam is emitted from the processing head (5). The workpiece (9) is processed by (8).

[Problem that the invention seeks to solve]

By the way, in the conventional apparatus shown in Fig. 3, the workpiece (
8) becomes larger, the Y-axis table (2) also becomes larger corresponding to the workpiece, and the amount of movement of the Y-axis table (2) also becomes larger in proportion to it. Therefore, the installation area of the laser processing device is required to be equal to the length of the Y-axis table (2) and the amount of movement of the table. That is, if the length of the Y-axis table (2) is L, the installation dimension of the laser processing device must be 2L or more, which poses a problem in that the installation area becomes large.

The present invention was made to solve the above problems, and
The present invention aims to provide a laser processing device that is smaller in size and has a smaller installation area.

[Means to solve the problem]

A laser processing apparatus is configured to move a processing head simultaneously in a direction opposite to a direction in which a workpiece moves.

[Effect]

With the above configuration, the movement of the Y-axis table on which the workpiece is placed in the Y-axis direction is only 1/2 that of conventional equipment, and the laser processing equipment can also be downsized and its installation area can be reduced. Become.

[Embodiments of the invention]

Fig. 1 is a side view of a laser processing device showing an embodiment of the present invention, and Fig. 2 is a plan view of the same. is a fixed table,
αυ is a moving beam, a'; a is a reflecting mirror.

As shown in the figure, the L-shaped saddle of the conventional device is divided into two parts: a fixed table (11) and a movable beam I, and the movable beam 0υ is constructed so that it can move in the Y direction on the fixed table mill I. A reflecting mirror was provided at the end of the moving beam 01).

As a result, the movement of the moving beam αυ in the Y-axis direction is always performed simultaneously in the opposite direction to the movement of the Y-axis table (2), thereby setting the processing position of the workpiece (9). The maximum amount of movement of the Y-axis table (2) in the Y direction is 1.5 times the length L of the workpiece (9). Therefore, the dimensions of the laser processing device can be reduced, and the installation area can be reduced.

Note that if the Y-axis table is fixed and only the movable beam aυ is moved in the Y direction, the device can be further miniaturized. This type is called the optical scanning type. However, this result laser (8)
The disadvantage is that the optical path becomes longer, and the displacement of the beam due to mounting errors in the reflecting mirrors in the optical path increases, resulting in a decrease in processing accuracy.

In this respect, the present invention is characterized in that the apparatus is made smaller while maintaining machining accuracy compared to the optical scanning type. Since it is configured so that it can move in opposite directions at the same time, compared to conventional devices that only move the workpiece,
We were able to achieve the excellent effect of miniaturizing the device and reducing the installation area of the device by more than 25%.
