Description
Technical field
The utility model belongs to high-precision optical lens detection technique field, is specifically related to the eccentricity detecting benchmark bearing of lens, lens combination.
Background technology
The lens eccentricity detecting can be divided into two kinds, circular arc type, monolateral stop type according to the bearing type at present, and rotating manner has manual stirring and two kinds of motor drivings.Optical lens processing enterprise generally adopts following two kinds of forms: 1. manually stir in conjunction with circular bearing, 2. manually stir in conjunction with monolateral stop type, this common advantage of two types is economical and practical.The bearing of metal or organic polymer material needs Renminbi approximately to be no more than 100 yuan, but this dual mode is for present high-precision optical lens, such as the interchangeable lens optical lens, high-definition monitoring camera lens optical lens, the precision needs have been difficult to satisfy, optical lens processing enterprise often needs artificial estimating to read, and causes the inaccurate of measurement.
To this, the most effective mode is to adopt the motor band to rotate with belt pulley at present, the detection method that the belt pulley drive lens is rotated, and the method can improve accuracy of detection, but detector hundreds of thousands, unit up to a million easily, cost is too high.
The utility model content
Be the defects that the solution prior art exists, the purpose of this utility model is to provide a kind of low cost, high precision, and the loading and unloading lens are convenient, and inclined to one side detection the in lens center that adapts to dissimilar lens detection used bearing.
for realizing above-mentioned order, the technical solution adopted in the utility model: this lens center is partially detected and is used bearing, has system base, it is characterized in that: described system base is provided with slidably V-block, V-block is fixed by fastener, also be provided with guiderail base on system base, guiderail base is provided with slide rail, slide block is equipped with on the slide rail of guiderail base, the side that described slide block is corresponding with V-block is provided with the rubber wheel that can contact with rims of the lens when detecting, the opposite side of described slide block is provided with elastic support apparatus, described V-block is provided with pore with the system base of the corresponding detection position of rubber wheel, described pore is connected with the negative pressure source of the gas.
On described system base, the detection position is threaded connection circular bearing, and the center pit of described circular bearing is connected with pore on system base.
On described system base, the position of corresponding V-type groove is provided with long slot bore, and screw rod is fixed by V-type groove and long slot bore.
Described guiderail base is fixedly connected on system base by the long slot bore on bolt, system base.
Adopt the beneficial effect of technique scheme: this lens center is partially detected and use bearing, the bearing aspect, and circular bearing and V-shaped groove are also deposited, the increase negative pressure device.Design can be changed the screw thread of circular bearing, the circular bearing of difformity, different sizes is installed with thread connecting mode according to different needs, at opposite side, the V-block that can adjust the position is arranged simultaneously, for the lens of different-diameter, by adjusting the position of V-block, improve versatility.In the bottom, be designed with aspirating hole, by connecting the negative pressure tracheae, realize contacting with the bearing negative pressure bottom lens to be measured, reduce to produce in the lens rotation process and beat.The rotation aspect is stirred rubber wheel with hand and is rotated, and rubber wheel rotation drive lens, lens combination are rotated, and replaces manual haptic lens and stirs the eyeglass rotation, and rubber wheel is arranged on dovetail groove, can adjust position and fixing, and realization is general to the different-diameter lens.V-block is fastened to each other by screw rod and bottom slot, can laterally adjust the position, with the part of corresponding different-diameter.
