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]
Mirror holder is regulated in the centering that the present invention relates to a kind of lens, and mirror holder is regulated in the centering that relates in particular to a kind of convex lens or concavees lens.
[background technology]
Because to the having relatively high expectations of centralized positioning, significantly displacement will influence the operation parameter of lens, and then influence the through performance of laser when convex lens or concavees lens use.
Fig. 1 to Fig. 3 is the structural representation of existing mirror holder; Existing mirror holder comprises: the lens mounting stand 20 of positioning seat 10, fixing len, the ball 30 between positioning seat 10 and lens mounting stand 20 and two jackscrews 40 regulating the eyeglass pivot angle; Because existing mirror holder has only the ball 30 of a location, lean on two jackscrews 40 to regulate pivot angle simultaneously, when jackscrew 40 is regulated; Eyeglass installation sleeve 20 is the center with unique ball 30; The center of ball 30 and eyeglass installation sleeve 20 lines of centres are the radius rotation, certainly will be that the center of eyeglass installation sleeve 20 produces displacement, influence the best operation parameter of lens.
[summary of the invention]
The present invention provides a kind of centering of eliminating the lens center offset phenomena fully to regulate mirror holder.
The embodiment of the invention is to realize like this; Mirror holder is regulated in a kind of centering of lens; Comprise: second positioning seat of first positioning seat, fixed lens, support whole adjusting mirror holder the 3rd positioning seat, second positioning seat is fixed on two first screws on the 3rd positioning seat, two first balls between second positioning seat and the 3rd positioning seat; The center line of said two first screws is vertical with the center line of lens; The line of centres of these two first balls and the central lines of lens, the line of centres of said two first balls is vertical with the line of centres of two first screws; Also comprise; First positioning seat is fixed on two second screws on the 3rd positioning seat, two second balls between first positioning seat and the 3rd positioning seat; The center line of said two second screws is vertical with the center line of lens; The line of centres of these two second balls and the central lines of lens, the line of centres of said two second balls is vertical with the line of centres of two second screws.
Wherein, each screw is installed with compression spring.
Wherein, the set nut that also comprises fixed lens.
The invention has the beneficial effects as follows: the present invention is provided with first holder and second holder through the front and back at the 3rd holder; The angle of regulating lens through the ball and the screw of front and back around the center line angle of lens simultaneously; About making lens can not occur or the situation that swings up and down displacement produce, reach lens with this and feel relieved fully.
