Description of drawings
Fig. 1 is the structural representation of automatic focusing bimirror of the present invention chamber laser cutting head.
The specific embodiment
Referring to Fig. 1, automatic focusing bimirror of the present invention chamber laser cutting head, be installed on 71 in the machine of laser cutting machine, comprise that pedestal 2 and order are installed in connector 3, focus lamp assembly 4, electric capacity head 5, nozzle 51, anticollision mechanism 6, automatic focusing mechanism 7 and the water-cooling ring 8 on the pedestal.
Be provided with guide rail 9 on pedestal 2, automatic focusing mechanism 7 is erected on the guide rail 9 and is fixedly linked with focus lamp assembly 4 and can drive focus lamp assembly 4 and move up and down, and is used to regulate the axial location of two microscope bases.
Anticollision mechanism 6 comprises microswitch 61 and spring 62, and microswitch 61 and spring 62 are separately positioned between the head 1 of connector 3 and laser cutting machine.Microswitch 61 collision detection are also sent stopping signal, absorb collision impact power thereby spring 62 is forced to compression, the protection cutting head.After collision was eliminated, spring 62 reset to guard mode, and cutting head resets and can continue cutting.
Water-cooling ring 8 is arranged between the first mirror chamber 41 and the second mirror chamber 42.Be used to cool off two mirror chambeies and microscope base that sets within it and eyeglass.
Also comprise the radial position that four cut-out governing knobs, 10, four cut-out governing knobs 10 circumferentially evenly distribute and are installed in the lower end of pedestal 2 and contact the adjustable nozzles that links to each other respectively with nozzle 51.
