Description
Technical field
The utility model relates to a kind of interferometer cubings for spheric glass detection.
Background technique
Spheric glass it is sub- this/partial face precision be optical imagery important indicator, needed after the completion of lens grinding using dry
Interferometer is inspected by random samples, and need to carry out full inspection confirmation to whole batch products when bad ratio is exceeded need to make when detecting on interferometer
It is positioned with interferometer cubing.Conventional dry interferometer cubing uses circumferential registration, i.e. jig inner hole (usually slightly larger than eyeglass outer diameter
For 0.1-0.2mm).Such cubing poor universality, when eyeglass outer diameter difference is greater than 0.5mm, locating effect is poor, Yi Pingyi, sub-
The offset of this imaging position, meanwhile, when production and processing, different model cubing, replacement frequency need to be needed to change for different model eyeglass
Height influences to check efficiency, and cubing quantity is more, will also result in the waste of production management and controls the raising of tool cost.
Summary of the invention
The purpose of this utility model be against the above deficiency place, provide a kind of interferometer cubing.
It is a kind of interferometer cubing that the utility model, which solves scheme used by technical problem, including rotary table, under rotary table in
Portion's setting positions inserting column, and column is arranged in middle part on rotary table, and rotary table periphery is provided with limiting slot, and rotary table, positioning inserting column, column are coaxial
The heart, and diameter successively successively decreases, eyeglass placed side is arranged in the upper end of the column, and the left and right sides milling flat of eyeglass placed side is at evacuation step
Face, evacuation step surface are located at below positioning surface, and locating piece is provided with before positioning surface, the outside arch in setting middle part on the inside of locating piece
At V-type positioning surface.
Further, V-type positioning surface includes the inclined-plane that two inner ends being symmetrical set are connected, between two inclined-planes
Angle be 120 degree.
Further, the linear distance of two inclined-planes outer end is less than the outer diameter of its eyeglass detected, and column diameter is greater than
The outer diameter of eyeglass detected.
Further, knuckle is arranged in the connecting pin on two inclined-planes.
Further, limiting slot is located on rear side of column.
Further, matcoveredn is set on positioning surface.
Further, protective layer is black wool paper.
Compared with prior art, the utility model has the following beneficial effects: structure is simple, design rationally, is operated with
It is convenient, it is versatile, inspection efficiency is improved, production cost is reduced.
Detailed description of the invention
The utility model patent is further illustrated with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram one of this cubing；
Fig. 2 is the structural schematic diagram two of this cubing.
In figure: 1- rotary table, 2- positioning inserting column, 3- column, 4- eyeglass placed side, 5- locating piece, 6- evacuation step surface, 7- are protected
Sheath, 8- limiting slot, 9-V type positioning surface.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in Figs. 1-2, a kind of interferometer cubing, including rotary table, setting positioning inserting column in middle part under rotary table, middle part on rotary table
Column is set, and rotary table periphery is provided with limiting slot, avoids rotating in cubing use process, and rotary table, positioning inserting column, column are coaxial
The heart, and diameter successively successively decreases, eyeglass placed side is arranged in the upper end of the column, and taking when to detect convenient for eyeglass improves and check efficiency,
The left and right sides milling flat of eyeglass placed side is located at below positioning surface, sets before positioning surface at evacuation step surface, evacuation step surface
It is equipped with locating piece, the outside arch in setting middle part is at V-type positioning surface on the inside of locating piece.
In the present embodiment, V-type positioning surface includes the inclined-plane that two inner ends being symmetrical set are connected, two inclined-planes
Between angle be 120 degree.
In the present embodiment, the linear distance of two inclined-planes outer end is less than the outer diameter of its eyeglass detected, column diameter
Greater than the outer diameter of eyeglass detected, locating piece height is 5mm, such structure, so that cubing can detecte the overwhelming majority directly
Diameter/R value is conducive to operate less than 1.65 or less shaped lenses；Circumferential registration is changed to V-type positioning surface, such improvement, inspection
The use scope of tool, which is extended within optic diameter difference 5mm, can be used, it is only necessary to this interferometer cubing of 5 kinds of specifications, i.e.,
85% or more in outer diameter 5mm-30mm routine eyeglass is covered, compares and is reduced with existing cubing, cubing specifications and models from more than 80
To 14 kinds, jig cost and management cost are substantially reduced, checks improved efficiency 15% to 20%, batch full inspection eyeglass improved efficiency
80% or more, save cost of labor.
In the present embodiment, knuckle is arranged in the connecting pin on two inclined-planes.
In the present embodiment, limiting slot is located on rear side of column.
In the present embodiment, matcoveredn is set on positioning surface, cubing in eyeglass test process is avoided to make lens surface
At scuffing.
In the present embodiment, protective layer is black wool paper.
When use:
(1) positioning inserting column is connect locking with detection platform, the limited block in detection platform is made to be placed in rotary table periphery
In limiting slot；
(2) eyeglass to be detected is placed on eyeglass placed side, the V-type positioning surface on located piece of eyeglass outer end carries out
Positioning.
(3) eyeglass placed is detected by interferometer.
Above-listed preferred embodiment has been further described the purpose of this utility model, technical solution and advantage,
It should be understood that the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all
