Description
Technical field
The utility model relates to a kind of optical detecting instrument, especially a kind of pick-up unit that is used to detect the rims of the lens thickness difference, specifically a kind of adjustable diameter rims of the lens uniform thickness device for detecting difference.
Background technology
As everyone knows, in order to satisfy the needs of optical system imaging, the centre of sphere that is arranged in each lens surface of system all should be on same straight line, and this straight line is called the optical axis of system.For single lens, the straight line by two centre ofs sphere is called optical axis, and the straight line by two curved surface summits is called geometrical axis, and geometrical axis is called centre deviation (representing with letter C) with misalignment (space crossed or parallel staggering) between the optical axis.
General lens processing all is to carry out thick, correct grinding earlier, polish again, last edging overlaps with optical axis and its geometrical axis that guarantees lens, and for the lens of edge uniform thickness difference Δ t (shown in Figure 1) greater than the formula set-point, can't its optical axis and geometrical axis be overlapped with the edging mode, so must measure and control its edge uniform thickness difference in thick, the correct grinding stage of lens.According to the knowledge of the applicant, it is available still not have the relevant detection device at present.
Summary of the invention
The purpose of this utility model is the problem that influences production efficiency and product quality at lacking the respective edges thickness detection apparatus in the lens processing, design a kind of can be apace to uniform thickness difference adjustable diameter rims of the lens that measure, highly versatile the uniform thickness device for detecting difference of rims of the lens.
The technical solution of the utility model is:
A kind of adjustable diameter rims of the lens uniform thickness device for detecting difference, comprise base 2 and adjustment disk 3, adjustment disk 3 is installed on the base 2, it is characterized in that three I shape chutes are arranged on the described adjustment disk 3, movably fulcrum frame 1 is installed in the chute, steel ball 7 and tightening are installed with annular knurl clamping screw 6 on each fulcrum frame 1, detection dial framework 4 is installed in the marginal portion of adjustment disk 3, detection table 5 is installed in and detects on the dial framework 4.
Described three fulcrum framves 1 angle each other is 120 degree.
The beneficial effects of the utility model:
The utility model has solved to produce and has been badly in need of, and is simple in structure, is applicable to that the lens of various diameters and thickness detect, and helps improve production efficiency and product quality.
It is poor that the utility model can advantages of simplicity and high efficiency be measured the edge uniform thickness of lens, need not add other survey instrument, only utilizes adjustment disk to change a spot size, thereby can measure the lens of diameter 10 to 140, is fit to all kinds of optics cold working enterprise and uses.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 2,3,4.
A kind of adjustable diameter rims of the lens uniform thickness device for detecting difference, comprise base 2 and adjustment disk 3, adjustment disk 3 is equipped with on the base 2, it is the chute (as Fig. 4) of 120 degree that three phase differential are installed on the described adjustment disk 3, fulcrum frame 1 is installed in the chute, the annular knurl fastening bolt 6 of rotating steel ball 7 and tightening location usefulness is installed on the fulcrum frame 1, be equipped with in the marginal portion of adjustment disk 3 and detect dial framework 4, detection table 5 is installed in and detects on the dial framework 4, as shown in Figure 3.
Using method of the present utility model is:
(1) the annular knurl fastening bolt 6 on the fulcrum frame 1 is unscrewed, regulated its size and lens 8 to be measured can be placed on middle.
(2) lens 8 to be measured are placed on the steel ball 7 on the fulcrum frame 1.
(3) position of adjusting fulcrum frame 1 can be rotated lens 8 (as shown in Figure 2) just on ball.
(4) the annular knurl fastening bolt 6 on the locking fulcrum frame 1.
(5) mobile dial gauge (or clock gauge) is on the marginal position of lens 8 gauge outfit.
(6) rotating the lattice number that lens 8 read pen travel above the dial gauge (or clock gauge), promptly is the edge uniform thickness difference of these lens.
Fig. 2 is a detection computations synoptic diagram of the present utility model, and work in-process needs external diameter is amplified 1.5mm, i.e. 31.5mm, and so according to lens edging surplus computing formula,
Δt＝ΔΦ(Φ+ΔΦ)(R1+R2-d)/2R1R2
＝1.5×(30+1.5)×(200+300-10)/2×200×300
＝0.19mm
The edging completion diameter of Φ---lens
ΔΦ---lens external diameter up-sizing
The radius-of-curvature value on R1, R2---lens two sides
D---lens center thickness value
Can draw in thick, correct grinding process, control edge uniform thickness difference is 0.19mm, after the correct grinding completion, select dial gauge to be installed on the dial framework, according to the step in the above-mentioned using method, regulate fulcrum frame 1, place lens 8, locking annular knurl fastening bolt 6 rotates lens, if the pen travel on percentage (or the thousand minutes) table 5 is in 19 lattice, then lens can go to polishing process; If pen travel surpasses 19 lattice on the dial gauge 5, eyeglass need be reprocessed so, and centering edge uniform thickness is poor again.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
