Description
Technical field
The utility model relates to optical mirror slip production testing field, is specifically a kind of thickness tool for detecting lens thickness.
Background technology
Along with the development of science and technology, optical mirror slip has been widely used in the technical fields such as digital camera, mobile phone, projector, video camera, and optical mirror slip needs to ensure higher purity, transparency, uniformity coefficient etc. in process of production.Optical mirror slip needs to carry out Thickness sensitivity to product after production completes, guarantee that the same thickness difference circumferentially of eyeglass is no more than 0.1% millimeter, existingly by thickness gauge, eyeglass to be detected, its part that comes with some shortcomings: directly by thickness gauge, eyeglass is detected, the pointer of thickness gauge slides and easily causes the wearing and tearing of minute surface on minute surface, and product quality is declined; In addition, because eyeglass is divided into convex lens and concavees lens, minute surface two end surfaces is not often at ordinary times, makes thickness gauge be difficult to location when measuring, thus causes measurement out of true.
Utility model content
Technical problem to be solved in the utility model: provide a kind of and eyeglass can be made not damage when measuring and make to measure accurately for detecting the thickness tool of lens thickness.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of thickness tool for detecting lens thickness, it comprises the thickness jig body of cylindrical structural, the upper surface of thickness jig body is provided with the circular groove for holding eyeglass, described circular groove inwall upper end is provided with the first ring groove for placing eyeglass from top to bottom successively, second ring groove and the 3rd ring groove, the internal diameter of the first ring groove is greater than the internal diameter of the second ring groove, the internal diameter of the second ring groove is greater than the internal diameter of the 3rd ring groove, first ring groove is provided with opening in circular groove inwall upper end, described circular groove outer wall symmetria bilateralis is provided with radial indentation.
Adopt said structure, the utility model is advantageously: adopt thickness tool, when measuring, optical mirror slip to be detected is put into the circular groove of thickness jig body, by thickness gauge, eyeglass is detected again, not that eyeglass is easily located when detecting, ensureing the degree of accuracy measured, ensureing that thickness gauge can not damage minute surface when detecting thickness simultaneously; In addition, circular groove inwall is provided with the first ring groove, the second ring groove and the 3rd ring groove, and the internal diameter of the first ring groove is greater than the internal diameter of the second ring groove, the internal diameter of the second ring groove is greater than the internal diameter of the 3rd ring groove, circular groove inwall upper end is provided with stair-stepping ring groove, thickness tool is made not to be only applicable to the eyeglass of different-diameter size, be applicable to concavees lens or the dissimilar eyeglass of two kinds, convex lens simultaneously, usable range is wide, do not need other making to be applicable to the thickness tool of two kinds of eyeglasses respectively, thus reduce production cost; Described circular groove outer wall symmetria bilateralis is provided with radial indentation, market there is a kind of structure be the oval eyeglass waiting other similar round structures, radial indentation is convenient to the placement of above-mentioned similar round structure eyeglass, eyeglass is made to place steadily when detect thickness, thus ensure the degree of accuracy of eyeglass lens measurement, in addition, radial indentation is also convenient to eyeglass and is put into or take out thickness tool, operates more convenient.
As preferably, described first ring groove and jig body upper surface excessive by arc, be convenient to eyeglass put into circular groove, structure is simple.
Accompanying drawing explanation
