Abstract
The utility model discloses a testing fixture facilitating observation of tiny deflection angles of a mechanism and relates to a detection clamp for observing or measuring two opposed tiny deflection angles on the mechanism. Two components having opposed tiny deflection angles and located on the mechanism are respectively provided with a holder. The two holders are each provided with a reflector in a mutually opposed way. A laser beam emitter is fixedly arranged on one holder. By means of laser beams reflecting back and forth between the faces of the two opposed reflectors (and finally irradiating one of the holders also serving as a screen), the testing fixture is enabled to achieve the same optical path as a conventional testing fixture does by directly irradiating beams on the screen in a distant way without a reflector and meanwhile maintains a relatively small reflector face installation distance (which signals a small size of the testing fixture). By using the optical lever amplifying principle, the testing fixture achieves effects of amplifying the relative deflection between the two components in a severalfold way and makes the observation of the tiny deflection angles easy. Meanwhile, an operator no longer needs to observe the beam spot in a distant way and is enabled to observe more conveniently and less distantly. Furthermore, the testing fixture has the advantages of simple manufacture, low price and practicality.
Description
[0002] technical field
The utility model discloses a kind of cubing of being convenient to observation element small deflection angle, relate to utilize the optical lever principle need to observe or measuring mechanism on the detection anchor clamps at two relative small deflection angles are arranged.
[0004] background technology
Usually need to detect relative small deflection angle between its upper two different positions of certain mechanism by detecting anchor clamps in the manufacturing industry, but often because deflection angle is too small, indistinguishable or precision not or observe inconvenient.For addressing this problem, having a kind of in the existing detection technique is by holder one light-beam transmitter to be installed on the part that small deflection is arranged on the member to be measured relatively, and make light beam irradiates on far screen, see the facula deviation basis of reference clearly thereby the amplification principle that utilizes optical lever can obviously show, made things convenient for to a certain extent observation small deflection angle.But this cubing needs far its optical lever effect of optical path distance competence exertion, can say also that in other words this cubing volume is very large, and usually be difficult to carry out because of the restriction that is subjected to indoor and operating environment, namely enable to implement, but the people who observes observes near can not standing in screen, though facula deviation is a lot of apart from amplifying, eye-observation hot spot distance is also followed far away, the eye-observation resolving power certainly will descend, partial offset its optical lever amplify the beneficial effect of skew.This is two obvious deficiencies in the prior art.
[0006] summary of the invention
The problem that exists in order to solve above-mentioned prior art, the utility model purpose is to provide a kind of and mechanism small deflection angle is observed become easier and personnel need not stand in remote screen next door and observe, also be that the cubing volume is relatively very little, make simultaneously simple, easy-to-use, the low cubing of easily popularizing of valency.
The utility model is to adopt following technical proposals to realize:
A kind of cubing of being convenient to observe member small deflection angle comprises: laser beam transmitter; Screen; It is characterized in that: respectively connect a holder on two different parts at the mechanism to be measured need relative deflection of inspection or pitch angle, mutual subtend respectively is fixedly mounted with a plane mirror on this two holder; Light-beam transmitter adopts laser beam transmitter also to be packed on one of them holder, and Multi reflection and each time light path mutually stagger and do not overlap and finally reflex on the screen outside the catoptron back and forth between two catoptrons to make laser beam.
This cubing takes full advantage of the optical lever amplification principle, on two different positions at mechanism's need relative deflection of inspection or pitch angle, respectively connect a holder, particularly each mutual subtend is installed a plane mirror on two holders, and be fixedly mounted with a laser beam generator on the holder therein, make/and between two subtend mirror mirrors, come back reflective by laser beam, finally reflex on the outer screen of catoptron, make on less minute surface mounting distance and (mean namely that also the cubing volume is very little), can realize having identical light path with the technology of the direct telecurie irradiation screen of existing light beam no-mirror, also namely can utilize equally the amplification principle of optical lever, reach equally several times and amplify the relative displacement effect of two members, so that observing, the small deflection angle becomes easier, and the operator can observe hot spot nearby, need not the distant surveillance beam spot, it is more clear to observe, more convenient, make simultaneously simple, valency is low practical.
