[0024] Please refer to Figures 1 to 9 The embodiment discloses a high-precision and high-stability multi-dimensional lens adjusting mechanism. A lens 104 is arranged on the lens adjusting mechanism 1. For the convenience of description, the embodiment establishes a coordinate system as shown in Figure 2The coordinate system of the mechanism is shown: the side direction of the lens adjusting mechanism 1 is defined as the X direction, the long side direction is defined as the Y direction, and the vertical direction is defined as the Z direction. It should be noted that the above directions are only used to describe the relative relationship between the adjusting degrees of freedom, and do not limit the installation posture of the present application, so the mechanism can be flexibly installed according to the overall optical path layout.

[0025] As shown in Figure 1 , the lens adjusting mechanism 1 of the embodiment realizes multi-dimensional adjustment of the lens 104 through the combination of translational adjustment and attitude adjustment; the lens adjusting mechanism 1 can include a fine screw actuator device 101, a lens X-direction adjusting base 102, and an X-direction tension spring 103 arranged on the lens X-direction adjusting base 102, and integrates an RXRY rotating mechanism 105 for fine adjustment of the attitude of the lens 104 and a gap sealing device 106 for shielding the motion gap.

[0026] Please refer to Figure 5 , Figure 6 and in combination with Figure 8 , the lens adjusting mechanism 1 of the embodiment includes an attitude adjusting mechanism mounted on the translational adjusting base 709 and used to realize the fine adjustment of the attitude of the lens 104 around two mutually perpendicular directions; in the embodiment, the attitude adjusting mechanism constitutes an RXRY rotating adjusting mechanism body 8 and belongs to the RXRY rotating mechanism 105. Specifically, the RXRY rotating adjusting mechanism body 8 includes a rotating mechanism adjusting base 801, a rotating mechanism upper fixed plate 802, a rotating mechanism lens seat 808, two adjusting knobs 803, a top rod 807, a compression spring 806, and a knob locking bolt 804. The rotating mechanism upper fixed plate 802 corresponds to the lens seat upper fixed plate body 5, which is provided with an upper fixed plate mounting through hole 502 for assembly and fixation, an upper fixed plate light passing hole 506 for ensuring the light path, and left and right adjusting knob mounting screw holes 501 and 505 for mounting the two adjusting knobs 803; the lens seat upper fixed plate body 5 is also provided with a top rod mounting screw hole 504 for mounting the top rod 807, and can be provided with a left rectangular spring mounting hole 503. The rotating mechanism lens seat 808 corresponds to the lens seat model body 6, which is provided with a lens seat light passing hole 605 and a lens fixing groove 606 for fixing the lens 104, and is provided with a compression spring fixing screw hole 603 and a knob locking bolt mounting screw hole 601.

[0027] In the embodiment, the rotating mechanism mirror seat 808 is elastically connected to the rotating mechanism upper fixing plate 802 by the compression spring 806 and the compression spring fixing bolt 805, so that the rotating mechanism mirror seat 808 is kept in a controlled pre-tightening state after assembly. The two adjusting knobs 803 are respectively threadedly connected with the rotating mechanism upper fixing plate 802, the top rod 807 is threadedly connected or fixedly connected with the rotating mechanism upper fixing plate 802, and the top rod 807 is threadedly connected with the rotating mechanism upper fixing plate 802 through the top rod mounting threaded hole 504; the rotating mechanism mirror seat 808 abuts against the two adjusting knobs 803 and the top rod 807 to form three-point support. The rotating mechanism mirror seat 808 is provided with a guide structure matched with the adjusting knobs 803, preferably a left knob guide groove 602 and / or a right knob positioning hole 604, to limit the transverse movement of the adjusting knobs 803 relative to the rotating mechanism mirror seat 808 and provide a stable force transmission path. In order to ensure the holding ability after the attitude adjustment is completed, the attitude adjustment mechanism is also provided with a knob locking structure, preferably the knob locking structure includes a knob locking bolt 804, which is threadedly connected with the knob locking bolt mounting threaded hole 601 to lock the adjusting knobs 803 at the target attitude position.

[0028] Referring to Figure 3 with Figure 7 , the lens adjusting mechanism 1 further includes a translation adjusting mechanism along the X direction, which constitutes a translation mechanism body 7 and is used to drive the whole attitude adjusting mechanism to translate along the X direction. The translation adjusting mechanism includes an X-direction translation base body 3 and an X-direction translation base 708, a translation adjusting base 709, a fine-thread actuator 701, a positioning pin 702, a translation tension spring 704, a downward pressure spring 705 and a translation locking bolt 706 arranged on the X-direction translation base body 3; wherein the fine-thread actuator device 101 can include the fine-thread actuator 701. The X-direction translation base 708 is provided with an X-direction translation base mounting through hole 301 for assembly and fixation, and is provided with a fine-thread actuator mounting hole 305 for mounting the fine-thread actuator 701; the X-direction translation base 708 is also provided with an X-direction translation base light passing hole 302 to ensure the light path passing, and is provided with an X-direction translation base sealing groove 303 to cooperate with the gap sealing device 106 to realize shielding; in addition, the X-direction translation base 708 is also provided with an adjusting base mounting threaded hole 304 to connect or fasten with the upper structure. The translation adjusting base 709 is arranged above the X-direction translation base 708 and cooperates with it.

[0029] Referring to Figure 4, the translational adjustment base 709 corresponds to the adjustment base body 4, the adjustment base body 4 is provided with an upper fixed plate mounting threaded hole 401 for mounting an upper structure, is provided with an adjustment base light hole 402, and is provided with an adjustment base mounting through hole 403 for assembly and fixation; the adjustment base body 4 is also provided with a tension spring fixing bolt mounting threaded hole 404 for mounting the tension spring fixing bolt 703, and is also provided with a mirror seat mounting square groove 406, a positioning pin groove 405, and a rectangular spring mounting through hole 407, and the like.

[0030] In the embodiment, the positioning pin 702 is used to provide linear guidance in the X direction for the translational adjustment base 709. Preferably, two positioning pins 702 constitute an X-direction positioning axis, and the translational adjustment base 709 forms a sliding guide fit with the positioning pin 702, so that the translational adjustment base 709 is limited to move in a predetermined linear direction during adjustment, thereby inhibiting transverse movement and deflection. The translational tension spring 704 is used to apply a pre-tension in the X direction to the translational adjustment base 709, and the two ends of the translational tension spring 704 are fixed on the X-direction translational base 708 and the translational adjustment base 709 through the tension spring fixing bolt 703 respectively; in the embodiment, the X-direction tension spring 103 can correspond to or include the translational tension spring 704. The downward pressing spring 705 is arranged between the X-direction translational base 708 and the translational adjustment base 709, and is pre-compressed through the downward pressing spring fixing bolt 707, so as to apply a downward pressing force to the translational adjustment base 709 towards the Z negative direction, so that the translational adjustment base 709 is attached to the guide and supporting surface, and Z-direction lifting or gap jumping during adjustment is avoided.

[0031] The fine threaded actuator 701 is mounted on the X-direction translational base 708, and the top rod thereof is in abutment with the force receiving and pushing surface of the translational adjustment base 709. In the initial position, the translational tension spring 704 applies a pre-tension to the translational adjustment base 709; when the fine threaded actuator 701 is rotated clockwise, the top rod pushes the translational adjustment base 709 to move in the X positive direction, so as to realize precise translational adjustment in the X direction; when the fine threaded actuator 701 is rotated counterclockwise, the translational adjustment base 709 can move in the X negative direction under the force relationship between the translational tension spring 704 and the top rod of the fine threaded actuator 701.

[0032] In order to ensure the holding ability after adjustment is completed, the translational adjustment mechanism is also provided with a locking structure. Preferably, the locking structure includes a plurality of translational locking bolts 706, the translational adjustment base 709 is provided with corresponding through holes, and the X-direction translational base 708 is provided with threaded holes matched therewith; after the translational adjustment base 709 is moved to the target position, the translational locking bolts 706 are tightened to lock the translational adjustment base 709 to the X-direction translational base 708, so as to realize fixation after adjustment.

[0033] Please refer to Figure 9The gap sealing device 106 comprises a gap sealing mechanism 9, which comprises a gap sealing cover plate 901, a gap sealing ejection plate 902 and a gap sealing spring 903. The gap sealing ejection plate 902 is in a gap fit with the gap sealing cover plate 901, and the gap sealing spring 903 is arranged between the translational adjustment base 709 and the gap sealing ejection plate 902 and is in a pre-pressing or pre-stretching state. When the translational adjustment base 709 moves in the X negative direction, the gap sealing spring 903 stretches to push the gap sealing ejection plate 902 to move in the X positive direction, so that the gap sealing ejection plate 902 shields the gap between the adjustment base and the adjacent structure; when the translational adjustment base 709 moves in the X positive direction, the gap sealing spring 903 is compressed to make the gap sealing ejection plate 902 move in the X negative direction, which also shields the gap.

[0034] In summary, the multi-dimensional lens adjustment mechanism provided by the embodiment comprises a posture adjustment mechanism and a translational adjustment mechanism. The posture adjustment mechanism realizes high-resolution fine adjustment and stable retention of the posture of the lens 104 through elastic pre-tightening of the compression spring 806, three-point support formed by the two adjustment knobs 803 and the top rod 807, guidance and limiting of the left knob guide slot 602 and / or the right knob positioning hole 604, and locking and retention of the knob locking bolt 804. Meanwhile, the translational adjustment mechanism keeps the translational adjustment base 709 in controlled fitting and gap suppression within the stroke through the combination of the positioning pin 702 guidance, the translational tension spring 704 pre-tightening and the downward pressing of the downward pressing spring 705, and cooperates with the gap sealing device 106 to shield the movement gap, thereby reducing the backlash, hunting, jamming and post-adjustment drift risk in the adjustment process, and improving the stability of multi-dimensional adjustment and the repeat positioning accuracy.
