Abstract
The utility model discloses an oscillating laser cutting head with adjustable focus and belongs to the technical field of laser processing. The oscillating laser cutting head with the adjustable focus comprises a headstock, a pair of reflecting lenses and lens seats, a direct drive motor, a swinging head, a lens cone, a reflecting lens with variable curvature, a focus lens, a sealing device, a capacitive sensor, a spraying nozzle and a water-pressure control system. One end of the direct drive motor is connected with the headstock in mechanical and fixation mode and the other end of the direct drive motor is connected with the swinging head in mechanical and swing mode. Laser is emitted by the pair of reflecting lenses, the lens seats, the reflecting lens with the variable curvature, the focus lens and the spraying nozzle. The reflecting lens with the variable curvature is arranged in the lens cone and connected with the lens cone in mechanical match mode. A position of the focus is displaced by the water pressure control system, the capacitive sensor and the sealing device in the processing. The oscillating laser cutting head with the adjustable focus can not only rapidly displace the focus according to different crafty requirements of laser punching and laser kerfing, but also automatically swing the head to process a trapezoid-shaped seam of high quality with high efficiency.

Background technology
General petroleum casing pipe can run into following problem when the trapezoidal seam of cutting:
1, when the trapezoidal seam of cutting, need cutting head that the yaw function is arranged.And general laser cutting machine tool, its cutting head does not have the yaw function, can not cut out the trapezoidal seam of outer narrow inner width.
2, when pulse laser punching and continuous laser cutting, need the change focal position.And general two dimensional motion laser cutting machine tool, its cutting head does not have the automatic stepless focusing system.When needing focusing, need the artificial focus lamp of changing the different fixing focal length, increased the secondary process time, machining accuracy is low, and production efficiency is low.
