Abstract

PURPOSE:To provide the laser cutting device enabling to reduce the space factor of the whole device with simple construction and made by providing a laser osccilator on the laser cutting device. CONSTITUTION:The main laser cutting device is composed of the laser cutting head 5 provided on the Y cursor 4, cursor 4 being fitted freely sliably to the Y beam 3, beam 3 to be connected to the X cursor 2, 2', cursor 2, 2' which are freely slidable along the side part of a cutting table 1, table 1. And a laser osccilator 6 is set up on the laser cutting device. The laser beam to be irradiated from the osccilator 6 is transmitted to the head 5 from the laser beam transmitting system 7. The head 5 then cuts with non-contact along the necessary cutting shape the sheet material developed and set on the table 1 by the transmitted laser beam.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a laser cutting device that cuts a sheet material in a non-contact manner.

[Prior art and its problems]

A laser oscillator used in a laser cutting device that cuts sheet materials without contact is an optical structure, and its assembly and adjustment requires highly precise technology. For this reason, in conventional laser cutting equipment, the laser oscillator is placed separately, the laser oscillator is fixed to a strong floor with anchor bolts, etc., and the laser beam is transmitted using a transmission system such as a mirror in the main body of the laser cutting equipment. is common.

In this way, with conventional laser cutting equipment,
Since the laser oscillator is placed separately from the main body of the laser cutting device, the space factor of the entire laser cutting device increases.

The present invention has been made in view of this point, and its object is to provide a laser cutting device that can reduce the space factor of the entire laser cutting device.

[Means for solving problems]

In order to achieve the above object, the present invention increases the rigidity of a laser oscillator so that the laser oscillator can be installed on a laser cutting device.

That is, the present invention includes a cutting table, an X cursor movable along the side of the cutting table, a Y beam connected to the X cursor, and an X cursor slidably attached to the Y beam.
Install the laser oscillator on the laser cutting knob by taking the installation means of housing the cursor and the laser cutting head attached to the X cursor, or (2) housing the laser oscillator inside the Y beam.

[Effect]

By installing the laser oscillator on the laser cutting device, the space factor of the entire laser cutting device can be reduced.

〔Example〕

Hereinafter, the present invention will be explained based on the drawings of the embodiments. 1st
The figure is a top view showing an embodiment of the laser cutting device according to the present invention, in which 1 is a cutting table, 2.2' is an X cursor that can be moved freely along the side of the cutting table 1, and 3 is this X cursor 2 and 2' is a Y beam connected to the Y beam, 4 is an X cursor slidably attached to the Y beam 3, 5 is a laser cutting head provided on the X cursor 4,
6 is a laser oscillator, and 7 is a laser beam transmission system. A laser oscillator 6 is connected to the X cursors 2 and 2' in parallel to the Y beam 3 as shown.

In this way, the laser oscillator β is installed on the laser cutting device, and the laser beam emitted from the laser oscillator 6 is transmitted to the laser cutting head 5 by the laser beam transmission system 7. Then, the laser cutting head 5 uses the transmitted laser light to cut the sheet material (not shown) laid out on the cutting table 1 along a desired cutting shape in a non-contact manner.

FIG. 2 is a top view showing another embodiment of the present invention in which a laser oscillator is installed on a laser cutting device. In the figure, the same reference numerals as in FIG. is a laser oscillator. The laser oscillator 26 is configured to be housed inside the Y beam 23 as shown in the figure, and the laser beam transmission system 7 irradiated from the laser oscillator 26
is transmitted to the laser cutting head 5.

〔Effect of the invention〕

As explained above, according to the present invention, the space factor of the entire laser cutting device can be reduced with a simple structure in which a laser oscillator is installed on the laser cutting device.
