The section of the honeycomb hole of the core layer is hexagonal. The processing quality of the optical platform is improved, materials are saved, and the precision of products is improved.
Description
Technical field
The utility model relates to a kind of optical test equipment, particularly a kind of optical table.
Background technology
In optical test, optical table is extremely accurate important tests equipment, it need have the resistance to shock and the dimensionally stable performance of height, it is by optical table and bracing or strutting arrangement be combined into, optical table places on the bracing or strutting arrangement with vibrating isolation system, with the influence that the minimizing extraneous vibration produces test, the height level who also keeps the optical table upper surface simultaneously, the optical test element forms light path system by screw retention on the optical table upper surface.The stable of the shape of optical table itself is the important step that realizes the optical test success or failure, it is subjected to the gravity of itself and the influence of test element gravity effect and environment temperature produces deformation, directly disturb the result of optical test, therefore, need be that optical table has the higher rigidity of structure and lower weight, higher stiffness/weight ratio can improve the resonant frequency of optical table, reduce the interference of extraneous vibration to test, higher stiffness/weight ratio can also reduce the deformation that the weight of himself weight and test element produces optical table, improve the measure of precision of optical test, improve system performance.In the prior art, optical table adopts steel plate to be welded into the structure of cross supporting bable tops more, because the cross diaphragm structure is subjected to weight and temperature effect, each is to discontinuity, the cross diaphragm structure makes optical table produce stress in welding, influenced the flatness of platform table top, test findings has been had a negative impact.How to improve the stiffness/weight ratio of optical table, select shape structure and the material more optimized for use, make optical table in use keep high precision, become technician's problem demanding prompt solution.
The utility model content
In order to solve the technological deficiency that prior art exists, the purpose of this utility model is to provide a kind of optical table, and this platform table top has higher flatness and stiffness/weight ratio, makes optical table can in use keep high precision.
To achieve these goals, the technical solution of the utility model is:
Optical table has top panel, side plate, lower panel, sandwich layer, has sandwich layer in the middle of the frame that side plate surrounds, and side plate and above the sandwich layer and following top panel and the lower panel of covering respectively has the array screw on the top panel, wherein:
Sandwich layer is the honeycomb hole sandwich layer; Sandwich layer and top panel and lower panel are bonded together by bonding agent.
Sandwich layer honeycomb hole cross sectional shape is a hexagon.
Core material is aluminium alloy, magnesium alloy, titanium alloy, aldary, kirsite, stainless steel, mild carbon steel, stone material or engineering plastics.
Adhesive material is epoxy resin, polyurethane or polyacrylic resin.
Because after adopting such scheme, the utility model in use adopts sandwich layer hexagonal cross-section honeycomb hole shape, has improved the stiffness/weight ratio of optical table, make optical table under stressing conditions and under the temperature variation, have each, also saved core material to consistance; Select for use the suitable material of optical table to constitute, make that optical table can be minimum to its precision influence when temperature variation; Adopt bonding agent bonding with side plate, sandwich layer top panel and following version, avoided welding heat, select suitable bonding for use, guarantee the bond strength of optical table and the precision of optical table the deformation influence that optical table produces.The technical solution of the utility model has improved the crudy of optical table, saves material, has improved the product precision.

Label in the accompanying drawing:
1. top panel, 2. side plate, 3. lower panel, 4. sandwich layer, 5. array screw.
Embodiment
Be further described below in conjunction with a kind of embodiment of Figure of description the utility model optical table.
Referring to a kind of optical table illustrated in figures 1 and 2, it has top panel 1, side plate 2, lower panel 3, sandwich layer 4, has sandwich layer 4 in the middle of the frame that side plate 2 surrounds, side plate 2 and sandwich layer 4 top and following top panel 1 and the lower panels 3 of covering respectively, has array screw 5 on the top panel 1, for the installation test optical element.Sandwich layer 4 is the honeycomb hole sandwich layer, sandwich layer 4 honeycomb hole cross sectional shapes are hexagon, adopt hexagon honeycomb hole material to be used as sandwich layer 4, be not only and save sandwich layer 4 materials, and can make between sandwich layer 4 and the side plate 2 respectively to stressed even, improve the stiffness/weight ratio of optical table, made optical table deformation minimum, guaranteed the test accuracy of optical table.Sandwich layer 4 materials can the aluminium alloy, magnesium alloy, titanium alloy, aldary, kirsite, stainless steel, mild carbon steel, stone material or engineering plastics, select for use suitable material to constitute, make optical table can when temperature variation, produce the deformation minimum, minimum to its precision influence.Sandwich layer 4 and top panel 1 and lower panel 3 are bonded together by bonding agent, the deformation influence of having avoided welding heat that optical table is produced, adhesive material can be selected epoxy resin, polyurethane or polyacrylic resin for use, select suitable bonding for use, guarantee the bond strength of optical table and the precision of optical table.
