Optical fiber bearing bracket of laser processing equipment

Abstract

The invention discloses an optical fiber bearing bracket of laser processing equipment, which adopts a framework structure, wherein the framework structure comprises a cross beam, an optical fiber bearing support, a left column and a right column; the cross beam and the optical fiber bearing support are parallel to each other; the left column and the right column span the cross beam and the optical fiber bearing support; the cross beam serves as a rail on which a laser head moves left and right; a hook component is arranged on the optical fiber bearing support, comprises a plurality of hooks which are distributed at intervals integrally, and can move left and right along the optical fiber bearing support; an optical fiber is led out of an optical fiber laser, and wound around the hooks in sequence in a ring-shaped manner; the tail end of the optical fiber is connected to the laser head; three pulleys are arranged on the optical fiber bearing support, the left column and the right column respectively; and two cables pass through the three pulleys clockwise and counterclockwise respectively, and are connected to the left and the right sides of the laser head and those of the hook component respectively, so that the laser head and the optical fiber move synchronously. According to the invention, the optical fiber can be fed stably and reliably during a laser processing process, and the fracture of the optical fiber can be avoided effectively.

Problems solved by technology

Although the optical fiber component itself can be bent with a certain radius to achieve flexible control of the optical fiber, it is easy to hinder other moving mechanisms of the laser processing equipment, especially the relative movement of the laser processing head in actual operation, resulting in the loss of processing accuracy; in addition, the direct Due to the lack of necessary bearing parts, the optical fiber connected between the laser and the processing head is also prone to breakage when it moves synchronously with the processing head, thereby reducing the processing efficiency

For example, CN1081107C discloses a laser processing device with flexible transmission and multi-axis linkage, which can realize flexible transmission in multiple directions of motion, and is suitable for processing large and complex curved workpieces, but its improvement mainly focuses on Regarding the driving method of the processing head itself and its supporting mechanism, the long-length optical fiber used as a gain medium is easy to be entangled or even broken during laser processing
