This embodiment includes three sets of adjustment assemblies, and locking assemblies are distributed on both sides of each adjustment assembly. The three groups of adjustment components are evenly distributed on the main mirror chamber 5, and each adjustment assembly includes a main mirror chamber insert 18 inlaid on the main mirror chamber 5, a receiving ball socket 21 inlaid on the bottom of the support base 4, and a socket set on the main mirror chamber. The adjusting screw 17 in the mirror chamber insert, the screw ball socket 19 embedded in the upper end of the adjusting screw, the steel ball 20 installed between the receiving ball socket 21 and the screw ball socket 19, and the lock nut 16 installed at the bottom of the adjusting screw .

每次调整过程,首先松开锁紧螺母16,旋转调整螺杆17,通过主镜室嵌件18实现了调整螺杆17的上下调整,连同螺杆球窝19、钢球20和承接球窝21共同实现了支承座4的倾斜调整。钢球和承接球窝以及螺杆球窝的作用在于释放相应的自由度,保证调整的时候不会引入局部应力。For each adjustment process, first loosen the lock nut 16, rotate the adjustment screw 17, and realize the up and down adjustment of the adjustment screw 17 through the main mirror chamber insert 18, together with the screw ball socket 19, the steel ball 20 and the receiving ball socket 21. The inclination adjustment of the bearing seat 4 is realized. The role of the steel ball, the receiving ball socket and the screw ball socket is to release the corresponding degrees of freedom to ensure that no local stress is introduced during adjustment.

结合图5和图7说明本实施方式,本实施方式所述的锁紧组件共三组,分布在调整组件的两侧。每个锁紧组件包括镶嵌在支承座上的滚子11、安装在滚子上的翘板8、安装在翘板两侧的靠板9、靠板上的安装螺钉10、通过翘板上的螺纹孔8-1实现螺纹连接的两个锁紧螺钉12、安装在锁紧螺钉上的锁紧球头15和锁紧球窝14以及蝶形垫片13。This embodiment is described with reference to FIG. 5 and FIG. 7 . There are three sets of locking assemblies in this embodiment, which are distributed on both sides of the adjustment assembly. Each locking assembly includes a roller 11 inlaid on the support seat, a seesaw 8 installed on the roller, a backing plate 9 installed on both sides of the seesaw, a mounting screw 10 on the backing plate, The threaded hole 8-1 realizes two locking screws 12 threadedly connected, a locking ball head 15, a locking ball socket 14 and a butterfly washer 13 installed on the locking screws.

每次进行主镜倾斜调整时,首先松开锁紧组件。通过旋转两个锁紧螺钉12,通过释放蝶形垫片13的预载保证后面的调整顺畅。锁紧组件通过滚子和翘板实现对支承座的锁紧,两个锁紧螺钉安装在翘板两侧,翘板底部设置了圆柱形凹槽,镶嵌在支承座上的滚子设置在翘板底部的圆柱凹槽内,松开一个锁紧螺钉即可进行调整组件的调整。这种结构类似于跷跷板,两个锁紧螺钉的锁紧力通过翘板平均的分布在滚子内,这种锁紧方式可有效的防止松动和憋死情况,两个锁紧螺钉上的锁紧力的差异不会对锁紧造成不利影响。调整完成后,旋紧锁紧螺钉12,锁紧球头15和锁紧球窝14的作用在于倾斜调整后,主镜室和翘板出现一个倾斜角,通过锁紧球头和锁紧球窝保证了锁紧时不会引入额外的应力,防止给调整组件带来锁紧误差。When adjusting the tilt of the primary mirror, first loosen the locking assembly. By turning the two locking screws 12 , by releasing the preload of the wing washer 13 , the subsequent adjustment is guaranteed to be smooth.

In the cylindrical groove at the bottom of the board, loosen a locking screw to adjust the adjustment assembly. This structure is similar to a seesaw. The locking force of the two locking screws is evenly distributed in the roller through the seesaw. This locking method can effectively prevent loosening and suffocation. The lock on the two locking screws Differences in tightening force do not adversely affect locking. After the adjustment is completed, tighten the locking screw 12, the function of the locking ball head 15 and the locking ball socket 14 is that after the tilt adjustment, the main mirror chamber and the seesaw will have an inclination angle, and the locking ball head and the locking ball socket will have an inclination angle. This ensures that no additional stress is introduced during locking, and prevents locking errors from being brought to the adjustment components.

本实施方式中,三组调整组件调整轴向位置,通过锁紧组件中的蝶形垫片13、翘板8调整沿光轴方向位置,蝶形垫片13配合翘板8和滚子11起到拉的作用,调节锁紧螺钉12起到顶的作用,这种调节方式可称为三顶六拉调节方式。In this embodiment, three sets of adjustment components adjust the axial position, and the position along the optical axis is adjusted through the butterfly washer 13 and the seesaw 8 in the locking assembly. The butterfly washer 13 cooperates with the seesaw 8 and the roller 11 To the effect of pulling, adjust the locking screw 12 to play the role of top, this adjustment method can be called three-top six-pull adjustment method.
