Gauge supporting device for lens surface precision detection

Abstract

A gauge supporting device for lens surface precision detection relates to the technical field of lens detection equipment and comprises a supporting ring, a rotating ring coaxially and rotatably clamped on the upper portion of the supporting ring and a clamping mechanism arranged between the supporting ring and the rotating ring, and a supporting net is arranged in the supporting ring. A plurality of arc-shaped sliding grooves are evenly formed in the rotating ring in the circumferential direction of the inner ring of the rotating ring, the distances between the two ends of each arc-shaped sliding groove and the center of the rotating ring are different,the clamping mechanism comprises a plurality of clamping pieces matched with the arc-shaped sliding grooves in a one-to-one correspondence mode. Each clamping piece comprises an execution part freely arranged between the inner ring and the outer ring of the supporting ring in a penetrating mode in the radial direction of the supporting ring, a limiting part slidably connected with the corresponding arc-shaped sliding groove and a clamping part connected with the execution part, the execution part is connected with the limiting part, and the clamping part is located in the supporting ring; and the rotating ring rotates to drive the limiting parts to slide in the corresponding arc-shaped sliding grooves, so that the clamping state of the clamping parts is changed.

Description

technical field [0001] The invention relates to the technical field of lens testing equipment, in particular to a testing tool support device for lens surface precision testing. Background technique [0002] When testing the precision of the mirror surface of the lens, it is necessary to use a support device to support the mirror surface, and it is also necessary to clamp the lens to prevent the lens from moving during the detection process, so as to affect the detection result; while the existing support device clamps the lens The holding method is generally to set a groove or fixture with a radius slightly larger than the radius of the lens on the support device. During the test, the lens is placed in the groove or the fixture for testing, but because the radius of the groove and the fixture is not variable, this method It can only satisfy a single-sized lens.

[0002] When testing the precision of the mirror surface of the lens, it is necessary to use a support device to support the mirror surface, and it is also necessary to clamp the lens to prevent the lens from moving during the detection process, so as to affect the detection result; while the existing support device clamps the lens The holding method is generally to set a groove or fixture with a radius slightly larger than the radius of the lens on the support device. During the test, the lens is placed in the groove or the fixture for testing, but because the radius of the groove and the fixture is not variable, this method It can only satisfy a single size of lens. If other lenses of different sizes need to be tested, different slots or fixtures need to be replaced, which increases the cost of testing and affects the efficiency of testing.
