Abstract
The invention relates to a weight-reduction synchronous moving mechanism of carrier sliding seat of grating ruling engine, belonging to the optical precision ruling technology field. The mechanism comprises basic seat, loading support, guiding rail, moving sliding vehicle, elastic chain with adjustable tension, cable, carrier sliding seat, lead screw pair, worm gear pair, indexing box and gearbox. The loading support is set on the basic seat and two guiding rails are set above the loading support. The moving sliding vehicle can move on guiding rails and two straight elastic chains with adjustable tension can be set at two sides of moving sliding vehicle respectively. Lower ends of elastic chains are fixed with the carrier sliding seat to play the role of weight reduction. The loading rail is fixed on the basic seat and the carrier sliding seat can move on the loading rail. When ruling the displacement of moving sliding vehicle is accomplished by the indexing box, gearbox and cable. The displacement of carrier sliding seat is accomplished by the lead screw pair, the worm gear pair and the indexing box. They are in phase.
Description
One, technical field
The invention belongs to the loading slide loss of weight synchronous moving mechanism of a kind of optical grating graduating machine that relates in the optical precision delineation technical field.
Two, background technology
Continuous development and social progress along with science and technology, the small size ruling grating can not satisfy current needs, along with technos is increasing to the large-area grating demand, the rose engine that can delineate the small size grating can not meet the demands, can delineate that large-area grating ruling is confidential very high input and develop one again, so technical difficulty is big, long insider of cycle just wants to transform on the original rose engine that can delineate the small size grating.When optical grating graduating machine is normally delineated, be that the grating blank is fixed on the loading slide of optical grating graduating machine, because small size ruling grating blank is in light weight, the suffered pressure of loading slide is little, the loading slide can move according to certain grating constant, and the weight of large tracts of land ruling grating blank is greatly about about 10~15Kg, the suffered pressure of loading slide increases, strengthened the frictional force between loading slide and the load-bearing guide rail, make the loading slide not carry out accurately moving according to certain grating constant, influence the quality of optical grating diffraction wave front, caused the grating distinguishing ability to reduce.So must take measures the loading slide is carried out loss of weight and reduce frictional force between loading slide and the load-bearing guide rail, just can make the rose engine of delineation small size grating possess the ability of delineation large-area grating.
The prior art the most approaching with the present invention is the loading slide carriage mechanism of the optical grating graduating machine of Changchun Institute of Optics, Fine Mechanics and Physics, CAS's development, as shown in Figure 1; Comprise: pedestal 1, load-bearing guide rail 2, loading slide 3, grating blank 4, sliding contact 5, bearing seat 6, screw 7, screw mandrel 8, worm gear 9, worm screw 10, calibration cabinet 11, belt pulley 12, travelling belt 13, worm screw seat 14.
Load-bearing guide rail 2 is fixed on the pedestal 1, and loading slide 3 contacts with load-bearing guide rail 2 by sliding contact 5 and can slide, and grating blank 4 places the central authorities of loading slide 3, and screw 7 is connected with loading slide 3.Being contained between screw mandrel 8 on the bearing seat 6 and the screw 7 is threaded engagement, and the right-hand member of screw mandrel 8 is connected worm gear 9 is housed, and worm gear seat 14 is connected with pedestal 1.Being contained between worm screw 10 on the worm gear seat 14 and the worm gear 9 is the tooth engagement, is connected with travelling belt 13 between the belt pulley 12 on worm screw 10 and the calibration cabinet 11.
The loading slide carriage mechanism of this optical grating graduating machine only adapts to delineation small size grating, can not delineate large-area grating.
Three, summary of the invention
In order to overcome the defective that prior art exists, the objective of the invention is to satisfy the demand of delineation large-area grating, a kind of loading slide of ad hoc meter loss of weight synchronous moving mechanism.
The technical problem to be solved in the present invention is: the loading slide loss of weight synchronous moving mechanism that a kind of optical grating graduating machine is provided.The technical scheme of technical solution problem comprises as shown in Figure 2: pedestal 15, load-bearing guide rail 16, loading slide 17, grating blank 18, sliding contact 19, bearing seat 20, screw 21, screw mandrel 22, worm screw seat 23, worm screw 24, first travelling belt 25, first belt pulley 26, second travelling belt 27, wheel box 28, second belt pulley 29, calibration cabinet 30, worm gear 31, around rope 32, pulley 33, pole 34, guiding rail 35, movable block 36, adjustable drag spring chain 37, leading block 38, carrying support 39.
Good effect of the present invention: the effect of loss of weight synchronous moving mechanism can realize to large-area grating delineation, simultaneously greatly reduce the delineation large-area grating cost, the loading slide in the delineation process, be not subjected to other external force influence, guaranteed the face shape quality of displacement accuracy and ruling grating.
