Background technology

Optical element often need be inserted, be withdrawn to Experiments of Optics repeatedly in light path, as lens, catoptron, optical filter etc., be used for adjusting, contrast, change light path.Require optical element to insert light path at every turn and have certain locus reseting precision, should have certain locus stability after inserting light path, in the time of needs, do not have excessive position creep, the variation of any locus all may cause the variation of light angle, after light path is propagated amplification, produce increasing deviation, will influence result of experiment.In addition, Experiments of Optics are carried out in the darkroom of being everlasting, and the mode of operation of inserting and withdrawing from should be simple and reliable.The physical dimension of implement device and the work space that needs can not be excessive.

The utility model provides a kind of special-purpose optical precision optical machinery adjustment rack, the opening and closing movement of simulation clam shell, optical element be can in light path, insert or withdraw from repeatedly by simple and reliable turnover mode, and the locus reseting precision and stability of certain optical element satisfied.

Summary of the invention

As Fig. 1, it is characterized in that: turnover body 1, long spring pull bar 2, straight pin 3, bearing 4, short spring pull bar 5, boss piece 6, hexagon socket cap head screw 8, base plate 7, holding screw 9, steel ball 10, extension spring 11 by constituting as the lower part.

As Fig. 2, described turnover body 1 is a mild carbon steel Q235 weld assembly, and postwelding should be removed welding interior stress, has square hole 12 and awl groove 13 on the turnover body.But square hole 12 sizes should satisfy inscribed circle pin 3 sizes, in connect the back and rotate flexibly, and Quenching Treatment is done on square hole 12 inwalls, awl groove 13 surfaces; Described bearing 4 is answered two pairing processing simultaneously, does adjustment notch, and machining state pairing recovery is pressed in strictness during installation; Described straight pin 3, boss piece 6, hexagon socket cap head screw 8, steel ball 10 are standard component.Except that steel ball 10, remaining parts is all done surface blackening and is handled.

As Fig. 1, straight pin 3 passes the square hole 12 of turnover body 1, the two ends extension is by pack into the left and right sides bearing 4 of pairing processing of adjustment notch, fastening by holding screw 9, left and right sides bearing 4 is anchored on base plate 7 by hexagon socket cap head screw 8, and circumferentially the turnover swing should be flexibly but along straight pin 3 axial no obvious plaies around straight pin 3 for fastening back turnover body 1.Long spring pull bar 2 is installed on turnover body 1 relatively, and short spring pull bar 5 is installed on base plate 7 relatively, and extension spring 11 is mounted on respectively between long spring pull bar 2 and the short spring pull bar 5.Boss piece 6 is installed on base plate 7 and is positioned at the rear of turnover body 1.Have awl hole 14 on the base plate 7.Steel ball 10 places in the awl hole 14 of base plate 7, and adds that micro-Instant cement is auxiliary to install and fix.But turnover body top plan fixing optical element.

As shown in Figure 3, turnover body 1 can be around straight pin 3 swings, and the opening and closing movement of simulation clam shell is realized turnover.Insertion state of the present utility model as shown in Figure 1, the awl hole 14 of awl groove 13, steel ball 10 and the base plate 7 of the conical surface that is formed by adjacent two walls of turnover body 1 upper aperture 12, the external cylindrical surface of straight pin 3, turnover body 1 limits whole degree of freedom of turnover body 1 jointly, and realization is located and reseting precision.The utility model main body is the mild carbon steel structure, has enough rigidity and intensity to guarantee the location and the stability that resets for compact optical element commonly used.Of the present utility modelly withdraw from state as shown in Figure 3, square hole 12, straight pin 3, two bearings 4 limit the turnover scope of turnover bodies 1, boss piece 6 supporting turnover bodies 1.Insertion state and withdrawing under the state, the pulling force Guarantee Status that departs from the extension spring 11 that turn down axis of oscillation is stable, and is auxiliary from just locating.Optical element is fixed in turnover body top plan, realizes inserting and withdrawing from.

The utility model positioning principle is simple.Under the insertion state, base plate 7 is fixed in the degree of freedom that only needs behind the work top turnover body 1 and is limited and get final product.12 liang of adjacent madial walls of square hole form 90 ° of V-shaped grooves, under the effect of gravity and extension spring 11 pulling force, contact with straight pin 3 external cylindrical surfaces, form positioning relation, make 1 surplus rotating in a circumferential direction and endwisely slipping of turnover body around straight pin 3 axis along straight pin 3 axis.Steel ball 10 contacts with awl groove 13, is split into positioning relation, with remaining all qualifications that rotates in a circumferential direction and endwisely slip.

The utility model implementation method is simple, is easy to operate in the darkroom.Turnover body 1 is located under the insertion state fully, and higher location and reseting precision are arranged.Integral body is steel construction, and enough rigidity and intensity are arranged, and bulk is less, and bi-directional scaling as required.Simple in structure, low processing cost.Behind the different surfaces processing mounting holes of turnover body 1, also can be used for various required occasions.
