Abstract
The utility model relates to a quick measuring tool for central thickness of an optical convex lens. The tool mainly comprises a portable meter stand and a check meter; the portable meter stand is provided with a base body with two backing claws; and the base body is provided with a concave lining core matched with the base body. The tool has the characteristics of simple structure, convenient operation, accurate measurement and the like.
Description
Technical field
The utility model relates to a kind of optical male lens center thickness speed and surveys cubing.
Background technology
In optics cold working industry, use portable thickness table and attached plastics taper chaining pin or rigid planar chaining pin thereof that the center thickness of optical lens is directly measured in a large number at present.The optical male lens mainly contain three kinds of shapes: biconvex lens, plano-convex lens, bent moon convex lens.Corresponding difform eyeglass uses different chaining pins to measure.Plastics taper chaining pin is used for the measurement of biconcave lens, plano-concave lens, bent moon concavees lens and bent moon convex lens four class eyeglasses.When using plastics taper chaining pin that biconcave lens, plano-concave lens, bent moon concavees lens and bent moon convex lens are directly measured, must repeatedly seek an action at center of lens, measuring speed is slow, inefficiency, seeking an action influenced by people's subjective factor, accuracy varies with each individual, and measuring error is bigger.And an action of seeking that continues also causes tested eyeglass surface damage easily, when biconvex lens, plano-convex lens are directly measured, must use the rigid planar chaining pin, and the hard chaining pin easily causes tested eyeglass surface damage.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, easy to operate, measure accurately optical male lens center thickness speed and survey cubing.
The utility model is to solve by following technical proposal: this cubing comprises portable dial framework, detection table, has with two matrixes by pawl to be mated on portable dial framework, has concave shape lining core to be mated on the matrix.
Two on the described matrix is 110 °-120 ° by the angle between the pawl.
Described width by pawl is 2-10mm.
Description of drawings
Fig. 1 is the utility model embodiment one-piece construction synoptic diagram.
Fig. 2 is the utility model embodiment basal body structure cut-away view.
Fig. 3 is the utility model embodiment concave shape lining cored structure cut-away view.
Embodiment
As shown in the figure, this embodiment comprises portable dial framework 1, detection table 6, on portable dial framework 1, have with two matrixes 2 by pawl 7A and 7B, there is concave shape lining core 3 to be mated on the matrix 2, two on the matrix 2 is 120 ° by the angle between pawl 7A, the 7B, and leaning on the width of pawl 7A, 7B is 2mm.During measurement, one of them face of convex lens sheet 4 as locating surface, is placed on the concave shape lining core 3 of cubing.Mention taper chaining pin 5, and allow the external diameter of eyeglass 4 hold out against two of cubing matrix to put down chaining pin 5 by pawl 7A, 7B, allow chaining pin 5 hold out against eyeglass 4 naturally, read reading; Mention chaining pin 5, take out eyeglass 4, finish the one-shot measurement action.
The principle of measuring: cubing is based on that relative measurement method designs.Measure earlier the center thickness value H of an eyeglass with the direct method of measurement, and with this eyeglass as follow-up measuring benchmark eyeglass.The benchmark eyeglass is put into cubing measure, draw reading Ha.Take out the benchmark eyeglass, put into eyeglass to be measured and measure, draw reading Hb.Practical center one-tenth-value thickness 1/10=the Hb-Ha+H of eyeglass to be measured.
In sum, the utlity model has simple in structurely, easy to operate, measure the characteristics such as accurate.
Claims (3)
1. an optical male lens center thickness speed is surveyed cubing, comprises portable dial framework, detection table, it is characterized in that: have on the portable dial framework with two matrixes by pawl to be mated, have concave shape lining core to be mated on the matrix.
