Abstract

A fiber laser beam machine includes a machining head that condenses a laser beam and irradiates the laser beam on a workpiece; a fiber that guides the laser beam output from a laser oscillator to the machining head; a fiber connector that fixedly joins the fiber to the machining head; a cable holding device such as a cable bear (registered trademark) that is flexible, is in a U shape, and houses the fiber; and a fixing section that fixedly joins the cable holding device to the machining head.

First claim

The invention claimed is:

1. A fiber laser beam machine comprising:
a machining head that irradiates a laser beam on a workpiece;
a fiber that guides the laser beam to the machining head;
a fiber connector that fixedly joins the fiber to the machining head;
a cable holding device that is made flexible and that houses the fiber;
a fixing section that fixedly joins the cable holding device to the machining head; and
a supporting section that detachably holds the fixing section, wherein
the machine head is supported by wires via fixing section, the wires being connected to the fixing section and the supporting section.

2. The fiber laser beam machine according to claim 1 , further comprising
a driving section that drives the machining head in a direction that is the same as an irradiation direction of the laser beam.

3. The fiber laser beam machine according to claim 1 , wherein
one end of the cable holding device is fixedly joined to the fixing section and the other end is fixedly joined to a member other than the fixing section.

4. The fiber laser beam machine according to claim 1 , wherein
the cable holding device is a bendable device.
