Ontology 100 is connected with the standard station 400 coordinated with distance keeper 500, and standard station 400 has with being placed on accommodating chamber The focusing surface that interior test target 102 flushes.I.e. focusing surface is located at same put down with testing the top surface of target 102 (target) Face is in same focal plane with the top surface for ensuring focusing laser beam and target.Distance keeper 500 has to generate reference laser beam First transmitting light path, for generate focusing laser beam second transmitting light path, reference laser beam be irradiated in focusing surface formed First hot spot, focusing laser beam is irradiated in focusing surface and forms the second hot spot, and the second hot spot can be by least through one It is overlapped after secondary deflection with the first hot spot.Preferably, storage distance keeper 500, raising portability, standard station 400 are set for convenience The cavity of distance keeper 500 can be stored by having.In addition, 400 outer surface of standard station carries dark application, it is double convenient for users to observing The coincidence degree of color laser drop point.Preferably, standard station 400 is provided with protection cap 402, to close or expose aforementioned sky Chamber.

The operation principle of distance keeper 500 is as follows：

When being focused, 500 position of distance keeper is first adjusted to ensure that reference laser beam and focusing laser beam are all radiated at pair On burnt surface, carry out trying molten operation at this time.When finding the focal length that can obtain best Pool by repeatedly trying focusing, lead to Focusing laser beam is overregulated so that the first hot spot and the second hot spot coincide, and can record current focus at this time.When removing use When the device 901 of auxiliary laser processing changes rapidoprint, need to only adjust the Z axis of laser Machining head 200 highly makes two beams The drop point of laser overlaps on rapidoprint surface can complete to focus again, and focus process has intuitive, convenient, rapid, precision The advantages that high.

Moreover, it is noted that in some instances, the test target 102 described in the present embodiment can also have with The identical material of workpiece to be added.For example, target material can be black alumina or stainless steel etc..The top surface of target passes through The marking of laser index carving technique is into the dial (index dial) with 360 degree of concentric scales.According to tested laser process machine with Technique, the indexing (as shown in figure 14) of different accuracy can be gone out by laser index carving technique marking by testing the index dial of target material surface, Different laser is macro, micro fabrication focusing demand to use, and technologist or researcher can easily correspond to different defocus The molten bath that parameter is formed.Index dial has concentric grid 802 and outer ring dial 801.In some instances, index dial can be with It is a workpiece to be set independently, and can be used with the test mating fixation of target.In this way, index dial can be by It is repeatedly used, and is used as a kind of repeatedly used universal tool.

For a kind of example optionally with the device processed in auxiliary laser proposed in the utility model, it is given below Operating process explanation：

First by the main body of the present apparatus, i.e., retainer 907 described herein is positioned over immediately below laser Machining head.It will observation Device 900 is whole to be screwed out to far from 907 side of retainer, and laser beam is enable to fall within test target across 103 center hole of cover board Top surface on 102.

Distance keeper is fixed on laser Machining head suitable position by clip 903 later, and adjusts distance keeper 500 and stretches out The laser beam that distance enables distance keeper to project is fallen on focal plane 401.

Further operating laser processing device carries out examination focus operation in top surface on test target 102, tests on target 102 Top surface, which is formed with, forms 360 degree of concentric grids and dial as shown in figure 14 using laser marking machine or other processing methods, It should ensure that the molten bath that focusing generates is fallen in concentric grid during focus operation；When carrying out examination focus operation using different focal length, often Changing a posterior focal distance, just rotation of adjustment knob 117 turns over a grid pitch by target 102 is tested, to distinguish repeatedly focusing behaviour Make the different molten baths generated；When test 102 upper surface of target can not can be drawn off in finishing after use by repeatedly focusing Top surface simultaneously engraves and retainer 907 is packed into after scale is continuing with.

There are many ways to proper focal length being determined using the present apparatus：Such as laser Machining head with auxiliary for auxiliary laser processing Device between distance have more than needed can every time examination focus operation after directly observe, and as needed focusing be adjusted so as to Find pinpointed focus.When distance is too small between the device that laser Machining head and auxiliary are processed for auxiliary laser, can use The mode of equal difference increment controls focal length, laser Machining head is made to promote or reduce every time certain value distance, forms multiple and different cokes Away from molten bath after, then the device for auxiliary laser processing will be assisted to remove machining position to observe Pool；When finding ideal The focal length to form the molten bath can be found after Pool according to the backtracking of its sequence, has also determined that pinpointed focus.

Viewer 900 is mainly applicable to further look at Pool after focus operation, especially for The relatively low laser of some power because the pool size of its formation is smaller visually more difficult, can be obtained using the amplification of viewer 900 To preferable observing effect.
