Description
Technical field
This utility model relates to optical instrument field, is specifically related to a kind of burnishing device for polarization splitting prism.
Background technology
Polarization splitting prism is a kind of optical element that a branch of incident illumination is divided into the mutually perpendicular two-beam in the direction of propagation.But different from general optical beam splitting element, it there is special relation between the two-beam separated, it may be assumed that they are all line polarized lights, and polarization direction is orthogonal.Polarization splitting prism can be divided into, incident non-polarized light, the line polarisation that two bundles are vertical.Wherein P polarisation is entirely through, and S polarisation is reflected with 45 degree of angles, and exit direction becomes an angle of 90 degrees with P light.
The difficult point of polarization splitting prism processing is in that how accurately to use the method for polishing to ensure angle and the flatness of intersection between two, so that the P polarisation of outgoing is entirely through, and S polarisation can be reflected with 45 degree of angles, and exit direction becomes an angle of 90 degrees with P light.
The polishing of polarization splitting prism generally uses conventional polishing process.Owing to polarization splitting prism structure is asymmetric, polishing needs manufacture and design a kind of angle precision and is better than the fixture of polarization splitting prism, polarization splitting prism is bonding with fixture, make the center of gravity centering place of bond, re-use conventional polishing process and be polished.Owing to polarization splitting prism is higher to the angle requirement of intersection between two, so needing the fixture precision prescribed designed and produced very high.And this optical polish method is relatively easy for corner cube prism, but for the polarization splitting prism in more than three face, its jig Design is considerably complicated, it is not easy to manufacture.
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of device can being polished for the polarization splitting prism in three faces, substantially increases polishing efficiency and the angle reached and surface precision is excellent.
For reaching above-mentioned utility model purpose, a kind of burnishing device for polarization splitting prism is provided, including base, head rod, the second connecting rod, clamp block, described head rod one end is connected to universal joint, the other end of head rod and second connecting rod one end are by pivot knuckles, and the connecting rod of described universal joint is fixed on base；Described clamp block is fixed on the other end of the second connecting rod.
Preferably, also include fixed block, be fixed between the second connecting rod other end and clamp block.
Preferably, described pivot having screw thread, threaded on pivot have fixing nut.
Preferably, described floor installation is on base plate.
Base center of the present utility model is processed as screwed hole, screw thread dress is processed in one coupling part of universal joint, it is threaded connection and is fixed on base, another link of universal joint connects head rod, head rod can rotate by any direction, head rod and the second connecting rod are hinged, and the second connecting rod can rotate upwardly and downwardly relative to head rod, and rotate by installing fixing nut restriction connecting rod on pivot additional.Different levels and rotational angle it is adjustable into by the linkage of head rod and the second connecting rod.This purpose is that plane polished for polarization splitting prism is placed in top, keeps the work platforms with numerical-control polishing equipment without inclination angle as far as possible.Before polarization splitting prism is fixed on whole device, need first that polarization splitting prism is glued together by the mode of heat bonding with clamp block.Design fixed block in order that polarization splitting prism glued together and clamp block are fixed together by cold-setting mode.When processing is near the plane of clamp block side, need to reinstall and clamp block is bonding
The beneficial effects of the utility model are to process polarization splitting prism with numerical-control polishing equipment, it is ensured that angle precision and surface figure accuracy, make P light and the minimum error angle outgoing of S light, greatly reduce the production time, improve production efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
A kind of burnishing device figure for polarization splitting prism according to Fig. 1, Fig. 2, is mainly made up of base plate 1, base 2, universal joint 3, head rod 4, pivot 5, fixing nut the 6, second connecting rod 7, fixed block 8, clamp block 9.In the construction shown in fig. 1, base plate 1 is fixed on the work platforms of numerical-control polishing equipment with four block pressur plates, be connected fixing with base plate 1 of base 2 is connected, there is a screwed hole at base 2 center, for by the connection between base and universal joint 3, universal joint 3 has two links, a link is processed screw thread and is connected with whorl of base, and another link is fixing connects head rod 4.Head rod 4 and the second connecting rod 7 are hinged by having threaded pivot 5, pivot 5 is cased with fixing nut 6, unclamps fixing nut, and adjustable-angle between head rod 4 and the second connecting rod 7, after tightening fixing nut 6, then angle is fixed.Head rod 4 and the second connecting rod 7 can may be adjusted to different angles and direction by universal joint 3 and pivot 5, it is necessary to can pass through unclamping or screwing control of fixing nut 6 during adjustment.First clamp block 9 is fixed together by bonding mode with polished polarization splitting prism 10 before processing, after fix with little fixed block 8 again.By regulating connecting rod direction and the angle of 4 and 7, plane polished in polished polarization splitting prism 10 is faced up fixing, angle precision and all excellent polarization splitting prism of surface figure accuracy can be processed by the debugging functions of numerical-control polishing equipment.
Below the preferred embodiment this utility model created has illustrated, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the premise without prejudice to this utility model creative spirit, and these equivalent modifications or replacement are all contained in the application claim limited range.
