Description
Technical Field
The utility model relates to an optical measurement equipment and optical parts alignment jig, in particular to vertical interferometer lift alignment jig mechanism that interferometry used.
Background
With the requirement of mass products (taking ten thousand pieces as a counting unit) such as mobile phone lenses, monitoring lenses and the like on the precision of optical cold machining becoming higher and higher, the vertical laser interferometer can be widely used in production fields because the vertical laser interferometer can quickly measure the aperture and the surface shape of spherical parts. In the vertical laser interferometer, a lifting adjusting frame system bears a measured piece and forms an interference cavity together with a standard lens. The requirements on quick and convenient adjustment, environmental interference on a production site and the like are much higher than those of a horizontal interferometer used in a laboratory.
First, the carrier adjustment stand needs to be stable. The standard lens and the measured spherical surface which form the interference measurement are connected together through the adjusting frame, and the stability of an interference pattern needs to be ensured. Therefore, the optical element is not afraid of synchronous vibration of the two optical elements and is sensitive to cavity length change generated by relative vibration of the two optical elements. In the field measurement environment, the adjusting frame is required to realize better rigid connection.
Secondly, the object-carrying adjusting frame needs to be lifted on the guide rail quickly and stably and can be stopped at any position. Therefore, there are various mechanisms such as a guide rail, a weight, a spring, and a screw. Where the guide rail and counterweight are the most common combination and the spring is typically used only in the light-weight trim system of the small interferometer and is also damaged. The screw is expensive and generally requires a counterweight balance adjustment frame to weigh. In a common lifting system, a steel wire rope for connecting a balance weight and an adjusting frame is exposed, but not beautiful, and rustproof lubricating grease on the steel wire rope is easy to touch to form a pollution source.
Third, the carrier adjustment frame needs to be able to lock at any height on the track. The conventional locking method is to clamp (or press) the surface of the guide rail or the vertical plate by using a mechanical structure. Both methods can generate a lateral force on the guide rail, the locking is loose, and the guide rail can creep up and down, so that interference fringes change in a long time to influence the continuous measurement of the interferometer; if the guide rail is tight, the straightness of the guide rail is adversely affected in the long-term use process, and a heavy guide rail with higher cost must be adopted.
