Technical background: in the industry now in order to deal with some complicated experiments and industrial use, is very tall to the requirement of parallelism of optical lens, the rough, flat enough flat lenses for milling is an important process of reduced optical lens edge thickness difference, in the end is to realize the lens diameter 1 mm larger than after edge grinding size, tolerance of + / - 0. 2 mm, and the thick milling center size 1 mm larger than the size of the finished product, convex curvature radius of curvature radius value is finished, the concave is finished small curvature radius, and need to measure size in the milling process, need to measure the ring, dial indicator and other tools. Figure 1 for an existing technology is commonly used in measurement of optical lens edge thickness difference of fixture - — Measuring ring 10, the hole in the center of the surface center is equipped with 11, 12, and on both sides of the radial slot with convenient take put the lens, lens is placed in the ring on the ring on the ladder 13 measuring edge thickness difference, but the fixture can only measure a diameter size of optical lens edge thickness difference, when measuring edge thickness difference of different specifications of the lens, the ring needs to be replaced, so you need to add extra different measuring fixture, the high cost. Technical implementation elements: the utility model to solve the technical problem is: to provide a measurement of optical lens edge thickness difference of the fixture, optical lens edge thickness difference of different outside diameter size measurement, is of strong regulatory, high flexibility, easy operation, and which can reduce the cost of measuring tool. In order to solve the technical problems, the utility model adopts the technical scheme is: to provide a measurement of optical lens edge thickness difference of the fixture, including: round base, described the circular base center is equipped with inner hole, used to leave to measure the lens; Described three slot, pass trough uniform circular base in stated, connect the outer edge of a circular base and inner hole, and described each pass trough with orbit; Described three movable sliding block, movable sliding block described respectively in each orbit, and described along the radial sliding orbit, move the slider towards described described inner hole set in one end of the block, is used to lift described for measuring the lens. Among them, the movable slide block are described with bolt, described at the end of the bolt to the mentioned in orbit. Among them, the circular base is made from stainless steel. Among them, described for the stainless steel bolt. Among them, described in the movable sliding block made from teflon. Beneficial effects of this utility model is to: different from the existing technology, the utility model in a circular base set up 3 bath, which has a track, and movable sliding block are installed in orbit, the slider towards one end of the inner hole is equipped with lifts for measuring lens block. Place the lens in the three block, adjust the slider, and according to the lens diameter makes the slider overhanging to equal to the length of the inner hole, and can even lift the lens, lens thickness difference of so as to realize the different diameter measurement, its adjustable is strong, high flexibility, easy operation, reduce the cost of measuring fixture. Figure 1 illustrated instructions for existing technology in measuring ring structure schematic diagram; Figure 2 as mentioned in the utility model measuring optical lens edge thickness difference of the fixture structure diagram. Concrete implementation way of this utility model in detail technical content, purpose and effect, which realize the combination method and comply with the appended drawings. Please refer to figure 2, the utility model provides a measuring optical lens edge thickness difference of the fixture, including: 1 round base, described the circular base 1 center is equipped with inner hole 14, for leave to measure the lens; Three slot 2, described on the homogeneous described in round 2 base on 1, connecting the outside edge of the circular base 1 14 and inner hole, and each described on slot 2 with orbit 21; Three movable sliding block 3, described in the movable sliding block 3 described respectively in each rail on the 21st, and orbit 21 radial sliding along the stated, move the slider towards 21 described above on one end of the inner hole of 14 has a piece of 22, is used to lift described for measuring the lens. Among them, described in the movable sliding block on the 3 bolts have 23, referred to one end of the bolt 23 into orbit 21 to stated. Among them, described the circular base 1 made from stainless steel. Among them, described in 23 for the stainless steel bolt. Among them, the movable sliding block described three made from teflon. Beneficial effects of this utility model is to: different from the existing technology, the utility model in a circular base set up 3 bath, which has a track, and movable sliding block are installed in orbit, the slider towards one end of the inner hole is equipped with lifts for measuring lens block. Place the lens in the three block, adjust the slider, and according to the lens diameter makes the slider overhanging to equal to the length of the inner hole, and can even lift the lens, lens thickness difference of so as to realize the different diameter measurement, its adjustable is strong, high flexibility, easy operation, reduce the cost of measuring fixture. In a concrete example, the utility model edge thickness difference measuring fixture material for stainless steel and POM ( Ptfe) And circular base is made of stainless steel material, in concentric circles set an inner hole, easy to lens mobile, in a circular base set up 3 orbital groove, the groove with adjustable moving slider ( POM material) , move the slider can move along the rail groove inside and outside, can according to the size of the lens to slide, and the bolts ( Stainless steel material) To tighten fixed. This lens can measure edge thickness difference in the fixture. Described above only for the implementation of the utility model example, not thus limit the scope of utility model patent, all use of the utility model specification and the appended drawings of the equivalent transformation, or directly or indirectly used in the related areas of technology, all in the same way included in the scope of the utility model patent protection. Technical features: 1.
