Description

Technical Field

[0001] This utility model relates to the field of laser cutting bed technology, specifically a high-safety laser cutting bed crossbeam. Background Technology

[0002] Laser cutting machines, as high-precision processing equipment, are widely used in the cutting of metal and non-metal materials. Traditional laser cutting machines typically employ an open or semi-enclosed beam structure, where the laser beam is refracted by a mirror and directly acts on the material being processed. However, under high-speed operation or abnormal conditions, there may be risks of laser scattering or leakage, posing a potential threat to operator safety. Furthermore, although some machines are equipped with external protective covers, they cannot completely prevent accidental laser leakage due to reflection, refraction, or mirror contamination. Especially during maintenance or debugging, workers still need to operate at close range, posing significant safety hazards. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a highly safe laser cutting bed crossbeam, solving the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-safety laser cutting bed crossbeam, comprising a crossbeam, with a machine head movably mounted on the upper end face of the crossbeam, the crossbeam including a right crossbeam support and a left crossbeam support, an optical path fixedly installed between the right crossbeam support and the optical path, a light source fixedly installed on the upper side of the crossbeam, a refraction cavity A, a refraction cavity B and a power cavity provided at the right crossbeam support, a refraction head bracket fixedly installed inside the refraction cavity A, a refraction head C fixedly installed on the upper end face of the refraction head bracket, a refraction head bracket A fixedly installed inside the refraction cavity B, and a refraction head D fixedly installed on the upper end face of the refraction head bracket A;

[0005] The machine head is provided with an outer protective plate, and a laser inlet is provided on the side of the outer protective plate near the right crossbeam support.

[0006] As a preferred embodiment of this utility model, the machine head is further provided with a machine head mounting frame. A power moving device and a refraction head B are fixedly installed on one side of the machine head mounting frame, and a carbon dioxide cutting head and a fiber optic cutting head are fixedly installed on the other side of the machine head mounting frame. A refraction head A is fixedly installed on the upper surface of the fiber optic cutting head.

[0007] As a preferred embodiment of this invention, the refraction head C, refraction head D, refraction head B, and refraction head A are arranged on the same horizontal plane.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The crossbeam of this laser cutting bed significantly improves the safety of equipment operation through multiple safety designs.

[0010] In terms of protective structure, the outer protective plate of the head and the crossbeam protective plate form a double-layer physical isolation, effectively blocking external impacts and the risk of internal laser leakage. The laser inlet adopts a directional channel design to avoid stray light scattering hazards and ensure precise beam transmission.

[0011] In terms of optical path safety, the enclosed refractive cavity strictly confines the high-energy laser beam within the cavity for transmission. Combined with precisely arranged refractive head assemblies, this eliminates the risk of energy leakage caused by optical path misalignment. Each refractive head maintains precise alignment on the same plane, further ensuring the stability of beam transmission.

[0012] These designs collectively construct a comprehensive safety protection system covering the entire process from laser transmission and processing to equipment operation, significantly reducing operational risks and equipment failure rates, and providing operators with a safer and more reliable working environment.
