Description

Technical Field

[0001] The utility model belongs to the technical field of lasers, and in particular relates to a split cross-line laser outer cylinder. Background Art

[0002] The precision adjustment structures of existing lasers are all integrated structures with debugging stress. A mounting hole is set at the head of the laser outer tube, and the horizontal cylindrical mirror and the vertical cylindrical mirror are installed in the mounting hole of the head of the laser outer tube with clearance fit, and then fixed by glue. Two symmetrical saw grooves are processed on the head of the laser outer tube, and the distance between the two saw grooves is only 1.5-2mm, so that the head of the laser outer tube is connected to the body, and two threaded holes are set at the saw groove positions on both sides. The set screws are screwed in for adjustment, so that the head can be slightly deflected around the saw groove connection part to achieve the best accuracy. The biggest drawback of this precision adjustment method is that it will generate large stress during the adjustment process. After the product debugging and assembly are completed, the stress will be gradually released. Along with the stress release, the accuracy will also change; secondly, the horizontal cylindrical mirror and the vertical cylindrical mirror are glued in the mounting hole, which is not conducive to the rework and repair of the product, thereby increasing the processing cost and rework cost of the product.
