Description

Technical Field

[0001] The utility model relates to the technical field of eccentricity detection, in particular to a reflective eccentricity instrument detection tool. Background Art

[0002] In the current optical cold processing industry, when performing reflective deflection inspection on lenses, the lens is placed flat under the reflective deflection instrument lens, placed on the measuring column through the lens platform and kept stationary, and the instrument lens Y-axis, X-axis, and Z-axis are rotated. The measured height distance and the set measurement parameters are adjusted so that the reflective parameters are displayed on the display panel.

[0003] However, this type of inspection fixture will have slight deviations when manually calibrating the focus point of each lens. It takes 1 to 3 minutes to calibrate a lens, which is too long, the operation steps are cumbersome, and the measurement efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to provide a reflective eccentricity meter inspection tool in order to overcome the defects of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A reflective eccentricity gauge, comprising an eccentricity gauge body; the eccentricity gauge body being fixed to a base by screws; the eccentricity gauge body being located directly below an eccentricity gauge lens and aligned with the center of the eccentricity gauge lens; a lens to be measured being placed on the top surface of the eccentricity gauge body, with a V-shaped clamp and a fixing plate for calibrating the focus of the lens being provided on both sides; the V-shaped clamp being provided on the left side of the eccentricity gauge body and being fixed on a straight handle; the fixing plate being provided on the right side of the eccentricity gauge body and being fixed on a bracket.

[0007] Furthermore, the V-shaped clamp is fixed to the straight handle by two M3 hexagonal screws; the straight handle is a straight handle that can be moved and adjusted laterally.

[0008] Furthermore, the fixing plate is fixed to the bracket by an M6 hand screw; the bracket is a fixed bracket.

[0009] Furthermore, the eccentricity gauge main body is a main body with a smooth and flat upper surface.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The utility model fixes the eccentricity gauge main body on the base and places it just below the eccentricity gauge lens, and then uses the V-shaped clamps on both sides to cooperate with the fixing plate to calibrate the focus of the lens, so that the lens can be placed more stably on the top surface of the eccentricity gauge main body, thereby avoiding the phenomenon of deviation when the lens produces focus point positioning, etc., improving the lens calibration accuracy, reducing the measurement and calibration time, simplifying the operation steps, improving the lens yield, effectively reducing the scrapping of lenses caused by inaccurate measurement, and reducing production costs. In addition, the reflective eccentricity gauge has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example

[0019] like Figure 1 and 2As shown, a reflective eccentricity gauge fixture includes an eccentricity gauge fixture body 9; the eccentricity gauge fixture body 9 is fixed to a base 10 by screws; the eccentricity gauge fixture body 9 is located directly below an eccentricity gauge lens 1 and is consistent with the lens center position of the eccentricity gauge lens 1; the lens 2 to be measured is placed on the top surface of the eccentricity gauge fixture body 9; the eccentricity gauge fixture body 9 has a smooth and flat top surface, which facilitates the stable placement of the lens 2; V-shaped clamps 4 and fixed plates 6 for calibrating the focus of the lens 2 are respectively provided on both sides of the eccentricity gauge fixture body 9; the V-shaped clamp 4 is provided on the left side of the eccentricity gauge fixture body 9 and is fixed to a laterally movable straight handle 5 by two M3 hexagon socket screws 3; the fixed plate 6 is provided on the right side of the eccentricity gauge fixture body 9 and is fixed to a fixed bracket 7 by an M6 thumb screw.

[0020] The working principle of this utility model is:

[0021] First, place the eccentricity gauge main body 9 together with the base 10 directly below the eccentricity gauge lens 1, ensure that the eccentricity gauge main body 9 is consistent with the lens center position of the eccentricity gauge lens 1, and be clamped between the V-shaped clamps 4 and the fixed disk 6 on the left and right sides, then place the lens to be tested on the top surface of the eccentricity gauge main body 9, and then by moving the straight handle 5, since the fixed disk 6 on the right is stationary, the eccentricity gauge main body 9 will be slightly offset left and right under the movement of the left V-shaped clamp 4, thereby focusing the lens 2, so that the measured height distance is adjusted to the set measurement parameters, and then fix the straight handle 5 without moving, and observe the lens 2. The reflective eccentricity parameter of the lens 2 will be displayed on a display panel connected to the eccentricity gauge lens 1.
