Description

Laser self leveling plumb aligner

The utility model discloses a kind of laser self leveling plumb aligner, relate to optical gauge technical fields such as laser plummet with automatic leveling compensator, spirit-leveling instrument.

At present, laser plummet with liquid Anping mostly is double-deck liquid form, but because the intermediate link of double-deck compensating liquid is many, precision further raising is restricted, though common reflecting liquid Anping can solve such problem, but the energy loss of instrument is serious, more than two kinds all have the systematic reflection veiling glare that is difficult to eliminate and influence the effect of practical application.

The utility model provides a kind of laser self leveling plumb aligner, has solved the laser plummet in double-deck in the past liquid Anping, the liquid level reflection veiling glare problem of spirit-leveling instrument, has solved the energy loss problem of the reflective Anping of common liq method.

Technical conceive of the present utility model is as follows: be made of plumb aligner body, inverting prism, laser collimation device, inclined mirror, compensating liquid device, the compensating liquid device is located at the bottom of plumb aligner body, in the compensating liquid device, plane mirror tilts to be placed on the bottom, one deck light-transmissive fluid is put in its top, planar lens seals compensator, is provided with laser collimation device above the vertical direction of compensator is provided with inverting prism, level, is provided with catoptron above tilting.

The catoptron of compensator can be reflection type, external reflection formula.The catoptron of compensator top comprises reflection type, external reflection formula and half-reflection and half-transmission beam splitting type.When using dichroic reflector, vertical collimator is used for two-way high precision Anping, less≤6 that should design of the angle between two optical axises of turning back by catoptron in the liquid ° at this moment, and light portion sees through spectroscope.

The planar lens that is used to seal comprises flat mirror and wedge mirror, and relative liquid surface is provided with the angle of one 0～20 degree.

The catoptron of laser beam horizontal sheaf liquid top reflects the plane mirror that directive liquid medium dip is along inclined direction placed through it, and light penetrates vertically upward afterwards.When the light of She Chuing was reflected into horizontality through the plane dichroic reflector vertically upward, device was used for horizontal Anping; Vertically upward light through the inverted image mirror reflects after again when plumbness penetrates, device is used for vertical Anping.

Good effect of the present utility model is: owing to adopt the reflection compensating liquid, eliminated the liquid level reflection veiling glare that liquid Anping method is difficult to overcome, can under the little situation of energy loss, realize accurate vertical Anping, device volume further reduces, structure is simpler, debugging is more prone to, and cost is low, makes the practicality of the foolization of level one plumb aligner require to become possibility.

Further specify the utility model below in conjunction with embodiment:

Fig. 1, be structure principle chart of the present utility model.

Fig. 2, be miniature laser level--plumb aligner.

Fig. 3, be plumb aligner.

See Fig. 1, be structure principle chart of the present utility model.Relative liquid surface tilts to put a plane mirror 2 below layer of transparent liquid 3, this catoptron comprises reflection type, external reflection formula and beam splitting type, liquid and catoptron are enclosed in the housing 1 by planar lens 4, the light 8 that laser collimation system 12 sends penetrates along plumbness 6 after its reflection through catoptron 5 reflection rear-inclined directive liquid midplane catoptrons 2.The light that penetrates through catoptron 10 ' be reflected into level 9 ' direction the time, be used for horizontal Anping; When the light that penetrates is turned back the direction of back along vertical 9 through inverting prism (10), be used for the accurate Anping of hanging down.

See Fig. 2, miniature laser level--plumb aligner: light beam 8 levels of laser collimation system 12 penetrate, be reflected into light 7 through level crossing 5, become vertical upwards state 6 to penetrate after level crossing 2 reflections in liquid 3, light beam sees through the glass 4 of closure casing 1 afterwards, again through spectroscope 10 ' separated into two parts: 9 ' be reflected into horizontality, directly by automatic horizontal Anping; 6 ' continue vertical making progress, (a) turn back into vertical 9 directions referring to Fig. 2, through inverting prism 10 by accurate vertical Anping.The shaft axis 19 direction conllinear of 9 directions and magnetic bases 20 among the figure, the turning axle that is beneficial to use base carries out the self-correcting of system's verticality precision.13 play the cover glass effect simultaneously for the rotating double-optical wedge of verticality accuracy correction.16 is the levelness correction wedge, and totally 3～4 edges of screw 22 fixedly emits 21 circumference uniform distributions, is used for the correction of incident ray.Screw 22 ' totally 3～4 edges fixedly emit 21 ' circumference uniform distribution, are used for the thick correction of levelness precision.14 is cover glass.15 are used to indicate and limit the slant range of putting of base for the garden bubble.The body of each optical element in the 11 expression retainer instrument, the battery of 17 expression instruments, 18 is tool housing.

See Fig. 3, light beam 8 levels of laser system 12 penetrate, and are reflected into external mirror 2 in the 7 directive liquid 3 through plane mirror 5, penetrate along plumbness 6 afterwards, and the other Chinese roof prism 10 that connects after system is turned back into vertical light 9 promptly by accurate vertical Anping.But for the diffraction of eliminating the ridge angle should make light beam avoid ridge rib place.The benhain prism of the no ridge rib of also available two quadratures of this prism is formed inverted image system (seeing accompanying drawing 3a) and is substituted the vertical Anping of realization.When the benhain prism 10 no ridge angles that connect after the system, can realize the self leveling of vertical guide instrument.If when connecing a pentaprism at light 9 places and it being rotated for the turning axle direction with the incident light axis, then system promptly becomes dynamic scanner.For the angle that system accuracy is improved between 6 and 7 should be less.Among the figure: 20 is magnetic adjustable base assembly, and 18 is shell, and 16 is battery, and 17 is the garden bubble, and 13 is rotating double-optical wedge, and 11 is system ontology, and 1 is the compensator housing, and inside vacuumizes by vacuum nozzle 19.As replace at the laser instrument place visual system then system be visual self leveling vertical collimator.
