Description
Technical field
This utility model relates to optical element detection, the especially detection of optical ball cover, belongs to optical element inspection
Survey technology field.
Background technology
At present, optical ball cover is mainly as satellite fairing, shell guidance trousers etc., at space flight and military neck
It is used widely in territory.The upper and lower surface of ball cover is two concentric spherical lenss, be equivalent to one parallel curved
Bent diaphragm.
The concentricity of ball cover surfaces externally and internally is one of its important technical parameter, and its required precision is the highest, logical
Often require that its concentricity reaches micron order, and owing to it is complex-shaped, the clamping during detection is also
Difficult point therein.
Existing concentricity is measured and is mostly used workpiece fixing means, first by the ball of detected element surfaces externally and internally
Within the scope of radius surface is worked into allowable error, on the basis of a surface and end face of element, surface carries out determining
Position, detects another surface altitude information at each discretization of half-space surface point of the position of distance end face equidistance, with
This judges its concentricity.The advantage of this kind of method is that principle is simple, easily realizes, and shortcoming is accuracy of detection
Low, high to the surface radius requirement on machining accuracy of tested ball cover, affect working (machining) efficiency, and surface radius is by mistake
Difference affects the judgement of concentricity testing result.
Utility model content
For the problems referred to above, this utility model provides a kind of ball cover concentricity testing device.
This utility model solves its technical problem the technical scheme is that optical ball cover concentricity detection dress
Put, including base plate, work rest, locating piece, upper amesdial, lower amesdial and column, work rest passes through
Locating shaft and locking nut connect has locating piece, locating piece to be provided with arc locating surface, and locating piece is through compressing spiral shell
Tethering and be connected to compact heap, work rest is connected with lower amesdial through lower dial framework, and column is through upper dial framework and upper amesdial
Connect.
The beneficial effects of the utility model are, it is achieved spherical crown, hemisphere and the concentricity of hemispherical optical ball cover
Detection, accuracy of detection is high, low cost of manufacture, the position error of measured workpiece and the mismachining tolerance of detection device
Impact on testing result is little.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is further illustrated.
Seeing Fig. 13, optical ball cover concentricity testing device, including base plate 1, work rest 2, locating piece
3, upper amesdial 10, lower amesdial 11 and column 13, by locating shaft 8 and locking nut on work rest 2
7 connections have locating piece 3, locating piece 3 to be provided with arc locating surface 6, and locating piece 3 connects through hold-down bolt 5
Having compact heap 4, work rest 2 is connected with lower amesdial 11 through lower dial framework 9, column 13 through upper dial framework 12 with
Upper amesdial 10 connects.
Locating shaft 8 is provided with axle sleeve 15.
This device is detected element to be rotated in adjustable extent, in element rotary course, utilizes upper and lower
Two amesdials detect the thickness difference of its diverse location point to realize the detection of concentricity.
Locating piece 3 is connected with work rest 2 by locating shaft 8 and locking nut 7, locating shaft 8 and locating piece 3
Between be fixed on locating piece 3 equipped with axle sleeve 15, axle sleeve 15, and rotate along locating shaft 8；Axle sleeve 15
Side higher than the side of locating piece 3, and with the contacts side surfaces of work rest 2, make locating piece 3 and work rest 2
Having gap, adjusting lock nut 7 can change the pressure between axle sleeve 15 and work rest 2, thus change
Frictional force when axle sleeve 15 rotates and between work rest 2, ensures locating piece 3 position when not driving simultaneously
Stable.
Locating surface 6 on locating piece 3 is arc surface, the inner surface radius phase of the radius of arc surface and workpiece 14
Deng, during clamping, workpiece 14 is placed on locating surface 6, rotatably compresses bolt 5 to drive compact heap 4 to compress
Element 14.
Manual actuation locating piece 3 rotates along locating shaft 8, the central axis of locating shaft 8 and arc locating surface 6
Sphere axis radius overlap.The diameter i.e. installed in rear horizontal direction with workpiece 14 overlaps.
Equipped with upper dial framework 12 on column 13, equipped with upper amesdial 10 on upper dial framework 12, on work rest 2 equipped with
Lower dial framework 9, equipped with lower amesdial 11 on lower dial framework 9, upper amesdial 10 and the telescopic table of lower amesdial 11
Bar center overlaps with the diameter on workpiece 14 vertical direction.
When being embodied as, with position shown in Fig. 3 as starting point, upper amesdial 10 and lower amesdial 11 data
Zero, manual rotation locating piece 3 drives workpiece 14 to rotate along locating shaft 8, rotates to diverse location and stop
Only, after upper amesdial 10, lower amesdial 11 video data are stablized, record this table and show data, Shang Qianfen
Data difference between table 10 with lower amesdial 11 is this thickness difference of workpiece 14 compared with starting point.Continue
Continuous rotation locating piece 3, records the starting point each discrete point thickness difference to workpiece 14 edge place section camber line
According to.Again clamping workpiece 14 is to change the relative position of itself and locating surface 6, it is possible to obtain workpiece 14 is different
The thickness difference data of the discrete point on section camber line.Owing to the surfaces externally and internally of ball cover is concentric, theoretic throat is each
Point uniform thickness, can obtain its concentricity result by the thickness difference data recording each discrete point.
During practical operation, lower amesdial 11 is covered by element, through polishing transparent workpiece it is observed that its
Table shows data, data wire can be used to export to the data of lower amesdial 11 calculate without the workpiece of polishing
Machine is carried out process and show in real time.
