Description
One, technical field
The invention belongs to the multi-functional grating notching knife of employed a kind of elastic top pin type knife rest in the grating development that relates in the spectral technique field and the delineation process.
Two, technical background
Grating is one of important core parts of optical dispersion in spectral technique.Every millimeter groove number does not wait to several thousand from the hundreds of bar.Generally the diffraction grating at visible light wave range is 600 lines per millimeter to 1200 lines per millimeters.In diffraction grating delineation process, the knife rest of adamas icking tool plays a part very crucial, and its structure directly influences the quality of delineation plane diffraction grating.It is reported and delineate the employed knife rest of plane diffraction grating in the past, great majority are cross elastic hinge formula structures, and the unit of domestic development, delineation plane diffraction grating generally adopts the knife rest of this structure.The prior art the most approaching with the present invention, be the ruling tool for grating knife rest of Chinese science Changchun optical precision optical machinery and physics Institute's development and production, shown in 1 (front view) and Fig. 2 (vertical view): comprise main carriage 1, cross spring leaf 2, secondary knife rest 3, adjusting bracket 4, fixture block 5, cutter lifting frame 6, adamas notching knife 7.
Adopt cross spring leaf 2 to connect between main carriage 1 and the secondary knife rest 3, adjusting bracket 4 and cutter lifting frame 6 all are installed in respectively on the secondary knife rest 3, and fixture block 5 is installed on the adjusting bracket 4, and adamas icking tool 7 is used for being installed.Rising and falling of adamas icking tool 7 finished for hinge axis by cross spring leaf 2, and the amplitude of rising and falling is by the load that is added on the knife rest degree of cross spring leaf 2 shapes to be decided.
The subject matter that this cross elastic hinge formula structure knife rest exists is: certain limitation is arranged in the use, can only delineate plane grating, can't be used to delineate concave grating, and adjust very difficult.Because the permission deflection of cross elastic hinge is 3～6 μ m, if deflection excessive when delineation diamond tool will produce vibration, cause adamas blade direction and adamantine direction of motion to produce deviation, cause grating facet rough, grating diffration efficient is reduced, so, the knife rest of this structure only be applicable to plane error less than the plane blank of 5 μ m on ruling grating.For the delineation concave grating, the knife rest of this structure is inapplicable, because the segment centre-height of general concave surface blank all is greater than 5 μ m.
Three, summary of the invention
In order to overcome the defective that above-mentioned prior art exists, the objective of the invention is to overcome the knife rest application limit, improve the grating ruling quality, be convenient to adjust a kind of multi-functional grating notching knife knife rest of ad hoc meter.
The technical problem to be solved in the present invention is: the multi-functional grating notching knife of a kind of elastic top pin type knife rest is provided.The technical scheme of technical solution problem comprises main carriage 8, sphere thimble 9, fastening V-arrangement axle sleeve 10, secondary knife rest 11, swinging bracket 12, adamas icking tool 13, fixture block 14, cutter lifting frame 15, fastening V-arrangement axle sleeve 16, fixed cover 17, stage clip 18, sphere thimble 19, slip balancing weight 20 as shown in Figure 3 and Figure 4.
Lower end, main carriage 8 both sides projection, make the bottom surface of main carriage 8 form Baltimore groove, center at the boss of lower end, both sides has the thimble axis hole, the thimble axis hole mounting spherical thimble 9 on the left side, between sphere thimble 9 and the thimble axis hole is threaded engagement, the thimble axis hole on the right is equipped with fixed cover 17, between fixed cover 17 and the thimble axis hole is that wringing fit contacts, sphere thimble 19 is housed in fixed cover 17, sphere thimble 19 can horizontally slip in fixed cover 17, and the extended fixed cover 17 of head is in fixed cover 17, stage clip 18 is equipped with on the right of sphere thimble 19, in order to roof pressure sphere thimble 19; The top axis hole of secondary knife rest 11 is inserted in the Baltimore groove of main carriage 8 bottom surfaces, fastening V-arrangement axle sleeve 10 and 16 are being inlayed in the two ends of axis hole above secondary knife rest 11, in the V-shaped groove that withstands on fastening V-arrangement axle sleeve 10 of sphere thimble 9 tightenings, play the role of positioning, sphere thimble 19 withstands in the V-shaped groove of fastening V-arrangement axle sleeve 16, the pressure of pressured spring 18 is eliminated the gap between main carriage 8 and the secondary knife rest 11 and is regulated the dirigibility of secondary knife rest 11 swings, make sphere thimble 9, fastening V-arrangement axle sleeve 10 and 16, sphere thimble 19 4 highly coaxial (OO ' axle) serves as the certain angle of axle swing but fastening V-arrangement axle sleeve 10 and 16 drives secondary knife rest 11 with OO '; The swinging bracket 12 that has a folding arm is screwed on the side of the moving direction of secondary knife rest 11, fixture block 14 is fixed on the vertical folding arm of swinging bracket 12, vertical installation gold hand hay cutter stone inscription cutter 13 below fixture block 14, cutter lifting frame 15 is by the edge flange of opening part, be screwed on the two ends of the same side of the fixedly swinging bracket 12 of secondary knife rest 11, make the blade with adamas icking tool 13 of arguing for the sake of arguing of cutter lifting frame 15 all be positioned on the center line of direction of motion of secondary knife rest 11, slip balancing weight 20, be installed in secondary knife rest 11 with install on swinging bracket 12 and the cutter lifting frame 15 rightabout sides, play balance and the adamas icking tool 13 and the effect of grating blank contact point size of adjusting secondary knife rest 11.
The principle of work explanation: the top by main carriage 8 is installed on the cutter bridge of optical grating graduating machine, the below auxiliary connection knife rest 11 of main carriage 8, the motion of cutter bridge is driving main carriage 8 and secondary knife rest 11 is done the delineation action, before operation, at first be installed in the adamas icking tool on the fixture block 14 and to adjust the direction of blade parallel with the direction of motion of cutter bridge, grating blank that then will be to be carved places the below of adamas icking tool, adjusting knife rest makes the point of a knife of adamas icking tool contact with grating blank surface, the size of contact point changes the position by slip balancing weight 19 and adjusts, after finishing, adjustment spurs cutter lifting frame 15 with the cutter lifting bar, secondary knife rest 11 is swung around OO ' axle, drive icking tool and break away from grating surface, try to carve after adding load on the fixture block 14, the load size that the incisure density difference is added is also different, under the effect of load, secondary knife rest 11 can be swung around OO ' axle, adamas icking tool 13 time do not break away from grating blank surface all the time in delineation, delineates, and the size of pressure has determined the grating cutting
Good effect of the present invention: the present invention can not only be used to delineate plane grating, also can be used to delineate concave grating, becomes one and is multipotency, and be convenient to adjust easy to use.
