Description
The utility model is the differential adjustable stand for precision optics mechanics of a kind of passive type.Be mainly used in the regulating mechanism of precision optics and precision optical machinery.
Prior art: in optical adjusting mechanism, the roof pressure structure of extensive use screw thread transmission realizes accurate the adjustment.Conventional adjustment rack supporting structure is a bikini, promptly rises as high as the banks, conical bore, plane.The advantage of this regulating mechanism is easy to adjust, uses flexibly, and higher resolution is arranged.Oneself is widely used in this class adjustment rack in the adjustment structure of all kinds of precision optics and precision optical machinery, and existing tandem product is (referring to document: 1.NewportCatalog, 1992.P.D1-E16.2.Micro Control Catalog, 1992, P.7.90-7.140.).But because the manufacturing resolution of fine thread is limited, be difficult to satisfy more high-resolution adjustment requirement, and fine thread serious wear in use, thereby resolution and stability that influence is adjusted.
The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, to provide a kind of preparation process simple, adjusts features simple structure, and it is higher to adjust resolution, good stability, the differential adjustable stand for precision optics mechanics of the passive type of long service life.
The structure of the utility model adjustment rack as depicted in figs. 1 and 2, it mainly comprises following components, last leading screw 1, go up stretched spring 2, support 3, adjust picture frame 4, stretched spring 5, leading screw 6, base 7 and connect ball 8 down down.Support 3 is a L type structure, and it is made of trailing arm 301 and transverse arm 303.Have screw 302 on the trailing arm 301, have screw 304 down on the transverse arm 303.Adjusting on a jiao of picture frame 4 has conical bore (402), monocline face skewed slot (401) and double inclined plane skewed slot (403) is arranged on tiltedly right in addition two jiaos respectively, as shown in Figure 2.The last screw 302 that has last leading screw 1 to pass on the trailing arm 301 of support 3 peaks on the monocline face of adjusting the monocline face skewed slot 401 on the picture frame 4.The following screw 304 that has following leading screw 6 to pass on the transverse arm 303 of support 3 peaks on the double inclined plane of adjusting the double inclined plane skewed slot 403 on the picture frame 4.Have last stretched spring 2 one ends to be fixed on the trailing arm 301 of support 3, the other end is fixed on to be adjusted on the picture frame 4.Have following stretched spring 5 one ends to be fixed on the transverse arm 303 of support 3, the other end is fixed on to be adjusted on the picture frame 4.Adjusting has the ball 8 of connection to contact with support 3 in the conical bore 402 on the picture frame 4, as shown in Figure 3.
The said leading screw 1 of going up is made of the decorative pearl on top of an official cap 101, screw mandrel 102 and handwheel 103; Following leading screw 6 is made of the decorative pearl on top of an official cap 601, screw mandrel 602 and handwheel 603, as shown in Figure 3, Figure 4.
From the above mentioned, last leading screw 1 and following leading screw 6 are the screw pair connection with the connection of support 3, last leading screw 1 is that the higher pair that the decorative pearl on top of an official cap 101 contacts with monocline face skewed slot 401 inclined-planes connects with the connection of adjusting picture frame 4, and following leading screw 6 is that the higher pair that the decorative pearl on top of an official cap 601 contacts with double inclined plane skewed slot 403 double inclined planes connects with the connection of adjusting picture frame 4.Support 3 and adjustment picture frame 4 link together by the higher pair connection of connection ball 8 and above-mentioned upper and lower two place's leading screws 1,6, and upper and lower stretched spring 2 and 5 then makes support 3 and adjusts picture frame 4 maintenance connections and certain pretightening force is arranged.Support 3 can be an integral structure with base 7, also can be that two bulk-breakings are fixed on support 3 on the base 7 with structures such as bolts.As can be seen from Figure 2, adjust three-point support on the picture frame 4 and be designed to monocline face skewed slot 401 (point of adjustment), conical bore 402 (adjusting fulcrum), double inclined plane skewed slot 403 (point of adjustment) by the rising as high as the banks of prior art, conical bore, plane three-point support architecture advances.The structure and the quality of upper and lower leading screw 1,6 are identical, and material can adopt No. 50 steel or T10 or T12 or CrWMn or GCr15 etc.Upper and lower leading screw 1 and 6 outside thread and the internal thread bedding-in of upper and lower screw 302 and 304 guarantee no gap and rotate flexibly.All post ceramic plate or corundum sheet on the double inclined plane of the monocline face of monocline face skewed slot 401, the internal surface of conical bore 402 and double inclined plane skewed slot 403.For alleviating the weight of adjustment rack, support 3 and adjustment picture frame 4 reach base 7 and all adopt aluminum profile extrusion.
Further specify structure of the present utility model and dynamic process below in conjunction with Fig. 3 and Fig. 4.As shown in Figure 3, is the inclined-plane and the angle of adjusting picture frame 4 surfaces of skewed slot 401 or skewed slot 403, and L is the center and the distance that connects ball 8 centers of the decorative pearl on top of an official cap 101 or 601, promptly regulates the distance of fulcrum apart from point of adjustment.D is the pitch of screw mandrel 102 or 602.θ is for adjusting the angle of picture frame 4 and support 3 trailing arms 301 or transverse arm 303.Distinguishable adjustment amount when Δ θ is adjustment.Distinguishable adjustment amount Δ θ can be expressed as: Δ θ=(Δ α/2 π) * d * cos /L.Δ α is the distinguishable corner of handwheel 103 or 603 in the formula, is generally 8.72 milliradians (promptly 0.5 °).This shows that the value of controlled resolution Δ θ depends on , d, L.Do not reducing pitch d and increasing under the condition of L, the value of adjusting can satisfy resolution requirement.The excursion of is 0 °～90 °.The adjustment rack of above-mentioned prior art can be seen a kind of special case of the novel adjustment rack of cost, the special case when promptly the inclination angle on two skewed slot inclined-planes is 0 °.At this moment the adjustment resolution that can regulate is adjusted picture frame 4 is: Δ θ=(Δ α/2 π) * d/L.This shows that under the d condition identical with L, the adjustment precision than prior art when is 60 ° doubles.When being 45 °, then improves 41.4% than the adjustment precision of prior art.When improving resolution, all post ceramic plate on the internal surface of skewed slot 401 and 403 inclined-plane and conical bore 402 or the corundum sheet is replaced metal support, can reduce the friction of supporting like this, improve the working life of adjustment rack.The supporting of use inclined-plane, also having a very important advantage is exactly to have improved the self-locking efficient of leading screw, because not only there is end thrust on the inclined-plane to leading screw in use, but also leading screw is had radial thrust.This radial thrust can improve the self-locking efficient of leading screw, thereby has increased the stability of adjustment rack.The differential adjustable stand for precision optics mechanics of this passive type can replace the optical adjusting frame of prior art, is widely used in the regulating mechanism of various product developments and all kinds of optics and precision optical machinery.And this passive type difference structure, also can be used for all kinds of conical sliding supports, be used for improving adjustment resolution and stability.
Advantage of the present utility model is: under the processing request that does not improve leading screw 1,6 pitch d, adopt the inclined-plane supporting, realized the differential adjustment of passive type, improved the adjustment resolution of adjustment rack.Utilize the radial thrust of inclined-plane, improved the self-locking efficient of leading screw, increased the stability of adjustment rack leading screw.Simultaneously post ceramic plate or corundum sheet on two skewed slots 401 and 403 the inclined-plane, replaced metal support, reduce the friction on the decorative pearl on top of an official cap and inclined-plane, improved the flexibility of adjustment, prolonged the working life of adjustment rack.The utility model has been used for actual regulating mechanism, has produced considerable economic.
