2, have crashproof function, can detect automatically and collide at any angle in the sagittal plane and instant the shutdown, avoided after collision is eliminated, can automatically restoring to original position and continuing cutting because of the operation or the improper cutting head damage that causes of programming.
3, eyeglass adopts water-cooled mode, has improved cooling effectiveness, prolongs eyeglass service life;
Description of drawings
Fig. 1 is the structural representation of manual focusing bimirror of the present invention chamber laser cutting head.
The specific embodiment
Referring to Fig. 1, manual focusing bimirror of the present invention chamber laser cutting head, be installed on the head 1 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, manual focusing mechanism 7 and the water-cooling ring 8 on the pedestal.
Manual focusing mechanism 7 comprises guide rail 71 and adjusts nut 72, and guide rail 71 is arranged on the pedestal 2, and focus lamp assembly 4 is erected on the guide rail 71 and can moves up and down along guide rail, adjusts upper end that nut 72 is installed in the focus lamp assembly and can drive the focus lamp assembly and move up and down; Be 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, 9, four cut-out governing knobs 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.
