Embodiment
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model
Limitation.
In the description of the utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width
Degree ", " thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer ",
The orientation or position relationship of the instructions such as " clockwise ", " counterclockwise " be based on orientation shown in the drawings or position relationship, be only for
Described easy to description the utility model and simplifying, rather than instruction or imply signified device or element must have it is specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.
A kind of fixing tool of optical lens center deviation difference Non-Destructive Testing of the present embodiment, as shown in the figure, 1 is test bench, 2 are
Locking wheel, 3 be fixed seat, and 2-1 is end cap, 2-2 is buckle, and 2-3 is swivel nut.
The top of fixed seat 3 is hollow connecting seat, and hollow connecting seat lateral surface has external screw thread, hollow connecting seat inner side
Face is inclined-plane.
The test bench 1 is hollow step ladder circular ring structure, and the depth of parallelism of the upper and lower end face of test bench is stringent, test bench it is big
Footpath end is smooth arc surface, and Glabrous thorn, for coordinating with tested optical lens, facilitates parts turn, miner diameter end passes through lock
