Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As Figure 1-4, a kind of laser machine Laser Transmission power compensating device, comprise laser instrument 1 and laser head 2, the light path 4 between laser instrument 1 and the focus lamp 3 in laser head 2 is provided with one and the light that light path 4 is cut off or is communicated with can be blocked device 5, light blocks device 5 and is connected with control device.
Described light blocks device 5 and comprises one and be arranged on cylinder 6 on the laser machine of light path 4 side, and the piston rod of cylinder 6 connects a light barrier 7 arranged along piston rod length direction, and light barrier 7 and light path 4 position are oppositely arranged, and cylinder 6 is connected with control device.When cutting discontinuous figure, when cylinder 6 receives the blocking signal that control device sends, cylinder 6 drives light barrier 7 pulling motion, and light path is cut off by light barrier 7; When cylinder 6 does not receive the blocking signal that control device sends, cylinder 6 drives light barrier 7 pulling motion, and light path is communicated with by light barrier 7, does not affect the normal transmission of light path.
Described light blocks device 5 and comprises one and be arranged on rotary magnet 8 on the laser machine of light path 4 side, the rotating shaft of rotary magnet 8 connect one with the vertically disposed light barrier 7 of rotating shaft, light barrier 7 and light path 4 position are oppositely arranged, and rotary magnet 8 is connected with control device.When cutting discontinuous figure, when rotary magnet 8 receives the blocking signal that control device sends, rotary magnet 8 drives light barrier 7 to rotate, and light path is cut off by light barrier 7; When rotary magnet 8 does not receive the blocking signal that control device sends, rotary magnet 8 drives light barrier 7 to rotate, and light path is communicated with by light barrier 7, does not affect the normal transmission of light path.
Described light blocks device 5 and comprises symmetry and be arranged on electromagnet 9 on the laser machine of light path 4 both sides, the push rod of each electromagnet 9 connects a light barrier 7 respectively, two light barriers 7 dock and arrange, and two light barrier 7 joints and light path 4 position are oppositely arranged, and two electromagnet 9 are connected with control device respectively.When cutting discontinuous figure, when two electromagnet 9 receive the blocking signal that control device sends, two electromagnet 9 drive two light barriers 7 to move respectively, and two light barriers 7 dock and light path cut off; When two electromagnet 9 do not receive the blocking signal that control device sends, two electromagnet 9 drive two light barriers 7 to move, light path is communicated with by two light barriers 7, do not affect the normal transmission of light path, light beam penetration power point of maximum intensity and beam center place first appear between two light barriers 7 in the process, thus acquisition cutting preferably penetrates effect.
Described light barrier 7 is astigmatism face towards a side surface of laser instrument 1, can say that laser beam leaves fast, can not injure bystander.
Adopt laser machine Laser Transmission power compensating device of the present utility model, structure is simple, easy to use, when cutting discontinuous figure, block device 5 action by control device control light and light path 4 is cut off or is communicated with, laser instrument 1 power supply is in on-state always, change and control the on/off of laser instrument 1 by control device in the past and reach the object controlling laser whether bright dipping, avoid laser instrument 1 power drop, ensure that front and back cutting effect is consistent, improve the processing effect of laser machine.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
