DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser processing machine for fixing a laser processing head to a frame and moving the work in the front, rear, left and right directions to perform laser processing on the work.

[0002]

2. Description of the Related Art Conventionally, as a combined punch / laser processing machine, for example, a turret punch press is provided on a portal-shaped frame and a laser processing head is provided in a hanging manner. There is known a type in which a carriage base movable in a direction is provided, and a carriage having a work clamp is provided on the carriage base so as to be movable in a front-rear direction.

In this punch / laser combined machine, a work is clamped to a work clamp, a carriage base is moved in the left-right direction, and a carriage is moved in the front-rear direction, and a desired position of the work is set to a punching position of a turret punch press. Alternatively, punching or laser processing is performed by positioning at a laser processing position immediately below the laser processing head.

[0004]

By the way, in the above-described conventional punch / laser combined machine, spatter generated during laser machining scatters on a slide-type ball screw or a linear guide rail for moving the carriage. As a result, there is a problem that the processing accuracy of the product is adversely affected.

An object of the present invention is to provide a laser processing machine which prevents spatters generated during laser processing from scattering on a slide system of a carriage and does not adversely affect product processing accuracy.

According to a first aspect of the present invention, there is provided a laser processing machine having a laser processing head suspended from a frame and moving in a lateral direction with respect to the laser processing head. What is claimed is: 1. A laser processing machine comprising: a carriage base provided with a work clamp; and a carriage provided with a work clamp provided on the carriage base so as to be movable in the front-rear direction, wherein a front end of the carriage base is provided on a left side surface of the carriage base. And a front bellows of the carriage and a second bellows at a rear end of the carriage base and a rear end of the carriage.

Therefore, when laser processing is performed on a work, the carriage base is moved in the left-right direction and the carriage is moved in the front-rear direction, so that a desired position of the work clamped by the work clamp is positioned immediately below the laser processing head. Is done. In this state, the workpiece is subjected to laser processing by irradiating the laser beam from the laser processing head toward the workpiece.

When the carriage is moved in the front-rear direction, the second bellows shrinks when the first bellows expands, and the second bellows expands when the first bellows shrinks. The second bellows prevents the carriage from being scattered on a slide system such as a ball screw or a linear guide rail. Thus, the product processing accuracy is not adversely affected, the life of the ball screw, the linear guide rail, and the like is improved, and high-speed processing can be performed.

According to a second aspect of the present invention, there is provided a laser beam machine according to the first aspect, wherein the frame is provided with a punch press.

Therefore, since the frame is provided with the punch press, the work is also punched.

The carriage is moved in the front-rear direction, and the desired position of the work clamped by the work clamp is positioned just below the laser processing head. In this state, the workpiece is subjected to laser processing by irradiating the laser beam from the laser processing head toward the workpiece.

When the carriage is moved in the front-back direction, the second bellows contracts when the first bellows expands, and the second bellows expands when the first bellows contracts. The second bellows can prevent the carriage from scattering on the slide system of the carriage, such as a ball screw or a linear guide rail. Therefore, it is not necessary to adversely affect the product processing accuracy, the life of the ball screw, the linear guide rail, and the like can be improved, and high-speed processing can be performed.

According to the second aspect of the present invention, since the frame is provided with the punch press, the work can be punched.
