Centering adjustment frame of lens

Abstract

The present invention relates to a centering adjustment frame of a lens, which comprises a first positioning seat, a second positioning seat used for fixing the lens, a third positioning seat used for supporting the whole adjustment frame, two first screws used for fixing the second positioning seat on the third positioning seat, and two first ball bearings arranged between the second positioning seat and the third positioning seat. The connecting line of the centers of the two ball bearings is overlapped with the central line of the lens. The centering adjustment frame also comprises two second screws and two second ball bearings, the two second screws are used for fixing the first positioning seat on the third positioning seat, the two second ball bearings are arranged between the first positioning seat and the third positioning seat, and the connecting line of the centers of the two second ball bearings is overlapped with the central line of the lens. The present invention has the beneficial effects that since the first fixing seat and the second fixing seat are respectively arranged in front of the third fixing seat and behind the third fixing seat, and the angle of the lens can be adjusted through adjusting the angles of the ball bearings and the screws around the central line of the lens, the lens cannot swing left and right or up and down, but can be completely centered.

Description

【Technical field】 [0001] The invention relates to a centering adjustment frame for a lens, in particular to a centering adjustment frame for a convex lens or a concave lens. 【Background technique】 [0002] Since the use of convex or concave lenses requires high center positioning, the obvious displacement will affect the use parameters of the lens, and then affect the transmission performance of the laser. [0003] Figure 1 to Figure 3 It is a schematic diagram of the structure of the existing spectacle frame. The existing spectacle frame includes: a positioning seat 10, a lens mounting seat 20 for fixing the lens, a ball 30 between the positioning seat 10 and the lens mounting seat 20, and two levers for adjusting the swing angle of the lens. A top screw 40, because the existing mirror frame has only one ball 30 positioned, and the swing angle is adjusted by two top screws 40 at the same time. The radius rotation of the line connecting the center of the lens mounting slee...

[0002] Since the use of convex or concave lenses requires high center positioning, the obvious displacement will affect the use parameters of the lens, and then affect the transmission performance of the laser.

[0003] Figure 1 to Figure 3 It is a schematic diagram of the structure of the existing spectacle frame. The existing spectacle frame includes: a positioning seat 10, a lens mounting seat 20 for fixing the lens, a ball 30 between the positioning seat 10 and the lens mounting seat 20, and two levers for adjusting the swing angle of the lens. A top screw 40, because the existing mirror frame has only one ball 30 positioned, and the swing angle is adjusted by two top screws 40 at the same time. The line connecting the center of the lens mounting sleeve 20 is a radius rotation, which will inevitably cause the center of the lens mounting sleeve 20 to shift, which will affect the optimal use parameters of the lens
