Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 1 ~ Fig. 3, the optical-fiber laser plumb joint for mid power that the present embodiment provides comprises focus lamp 1, spectroscope 2, protective glass chamber 3, protective glass 4, gas curtain 5, expands part 6, CCD connector 7 and water-cooled part 8.
Wherein focus lamp 1 is cuboid, and it comprises the focusing lens 11 focusing on microscope base 12 and be arranged in focusing microscope base 12, and two sides and the front and back sides of focus lamp 1 are plane, and there are screw hole and dowel hole in each face, so that install.
Spectroscope 2 is also cuboid, and it is vertically mounted on the upper surface of focus lamp 1, and 2 li, spectroscope has a light splitting eyeglass 21 of 45 degree of tilting, and this eyeglass can allow laser light, again can the blue light of reflection wavelength 470 nanometer.
Expand part 6, be vertically mounted on the top of spectroscope 2, its built-in a slice lens (not shown), the upper end expanding part 6 is connected with the optical fiber head of optical fiber laser (being called for short QBH) (not shown), expanding part 6 adopts water-cooling pattern to cool. and the profile expanding microscope base is square, and its two sides and front and back sides are all plane, and there are screw hole and dowel hole in each face, be convenient to install fixing, when making laser-beam welding machine high-speed motion, plumb joint is not easily trembled.
Protective glass chamber 3, is fixed on the lower surface of focus lamp 1, is mainly used to install protective glass 4, and the side in protective glass chamber 3 is provided with a card chamber, and protective glass 4 correspondence is installed in described card chamber.Protective glass 4 includes protection microscope base 41, protective lens 42 and handle 43; described protection microscope base 41 is connected with handle 43; described protective lens 42 is fixed in protection microscope base 41; and described protective lens 42 is planar lens; can ensure that focusing lens 11 and the external world separate, protection focusing lens 11 is from the pollution of the pollutant such as return slag and dust.Meanwhile, by changing protective lens 42, the stability of focused beam can be maintained, to ensure welding quality.
