Abstract
The invention discloses a testing fixture convenient for observing mechanism minimal deflection angles, referring to a detection clamp used for a mechanism with two relative minimal deflection angles needing observing or measuring. According to the invention, two members of a mechanism with relative minimal deflecting angles are respectively provided with a clamping member; and the two clamping members are respectively provided with a reflector in opposite directions, wherein one of the clamping members is fixedly provided with a laser beam generator, allowing / utilizing laser beams to reflect back and forth between two opposite reflector surfaces (finally irradiating to one clamping member also used as a screen); and at a smaller mirror surface installation distance (which means the size of the testing fixture is small), a same optical distance when light beams directly irradiate to a screen from a long distance without a reflector in prior arts can be realized; meanwhile relative offset of two members can be amplified by several times by utilizing the amplification principle of optical levers, so that minimal deflecting angles can be observed in an easier way, operators do not need to observe light beam spots at a long distance and an observation distance is closer and more convenient; meanwhile the testing fixture is simple to manufacture, has low price and is practical.
Description
Technical field
Patent disclosure of the present invention 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.
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.
The patent of invention content
The problem that exists in order to solve above-mentioned prior art, patent purpose of the present invention 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.
Patent of the present invention is to adopt following technical proposals to realize:
A kind of cubing of being convenient to observe member small deflection angle comprises: light-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.
