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 the present invention is places against the above deficiency, provide a kind of interferometer cubing and application method.
The solution adopted by the present invention to solve the technical problem is that a kind of interferometer cubing, including rotary table, middle part is set under rotary table
Positioning inserting column is set, 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 concentric,
And diameter successively successively decreases, the upper end of the column be arranged eyeglass placed side, eyeglass placed side the left and right sides milling flat at evacuation step surface,
It avoids step surface to be located at below positioning surface, locating piece is provided with before positioning surface, the outside arch in setting middle part is at V on the inside of locating piece
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.
A kind of application method of interferometer cubing, comprising the following steps:
(1) positioning inserting column is connect locking with detection platform, the limited block in detection platform is made to be placed in the limit of rotary table periphery
In slot；
(2) eyeglass to be detected is placed on eyeglass placed side, the V-type positioning surface on located piece of eyeglass outer end is determined
Position；
(3) eyeglass placed is detected by interferometer.
Compared with prior art, the invention has the following advantages: structure is simple, design is rationally, easy for operation,
It is versatile, inspection efficiency is improved, production cost is reduced.
Detailed description of the invention

Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
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
