Description

Technical Field

[0001] This utility model relates to the field of optical support adjustment technology, specifically to a multi-degree-of-freedom optical support adjustment mechanism for ballbar support. Background Technology

[0002] Existing optical bracket adjustment mechanisms mostly use a structure of threaded knobs and slide rails, which have problems such as limited adjustment freedom and insufficient stability.

[0003] Chinese patent application CN200820235054.6 discloses an optical adjustment frame, including a base, a fixing plate, a lens holder with a first light-transmitting hole, a base, a first threaded joint that moves the lens holder in a first direction, a second threaded joint that moves the lens holder in a second direction, a third threaded joint that moves the base in a third direction, and first and second elastic bodies that reset the lens holder in the first and second directions, respectively. The base has first and second guide surfaces that guide the lens holder, and a guide rail pair that guides the base in the third direction is fixed on the base. The base is located on the guide rail pair, and the fixing plate is fixed to the base. The first and second threaded joints are both located on the base, and the third threaded joint is located on the base. The first, second, and third directions are perpendicular to each other, and one of them is the optical axis direction. In the third direction, the lens holder is positioned between the base and the fixing plate. The above-described device uses guide surfaces for guidance and guide rail pairs for translational movement in another dimension, making the entire optical adjustment frame structure simple and compact.

[0004] However, the following drawbacks still exist:

[0005] It is difficult to achieve combined pitch and yaw adjustments, and the adjusted area is prone to displacement due to external forces. In addition, complex adjustments require multiple steps, resulting in low efficiency. Utility Model Content

[0027] Example

[0028] This embodiment provides a multi-degree-of-freedom optical support adjustment mechanism for a ball bar instrument, such as... Figures 1-4 As shown, it includes: a base 1, with suction cups 2 symmetrically arranged at the bottom of the base 1, and an optical mounting plate 5 arranged above the base 1; a ball bar support mechanism 3, arranged above the base 1, for adjusting the height of the optical mounting plate 5; a ball hinge 4, arranged on the ball bar support mechanism 3, for adjusting the angle of the optical mounting plate 5; a connecting mechanism 7, arranged below the optical mounting plate 5, for connecting the optical mounting plate 5 and the ball hinge 4; and an adjustment mechanism 6, arranged on the base 1, for adjusting the position of the optical mounting plate 5.

[0029] The multi-degree-of-freedom optical support adjustment mechanism for a ballbar, employing the above technical solution, includes an adjustment mechanism 6. A first motor 603 drives a first lead screw 602 to rotate, causing a first slider 604 to move along a first slide groove 601. A second motor 607 drives a second lead screw 606 to rotate, causing a second slider 608 to move along an adjustment seat 605, thus adjusting the position of the optical mounting plate 5. A ball joint 4 adjusts the angle of the optical mounting plate 5. Pulling the telescopic rod 302 adjusts the height of the optical mounting plate 5. A magnetic damping block 609 locks the positions of the first slider 604 and the second slider 608. The coordinated action of an arc-shaped brake pad 306 and a tension spring 307 locks the height of the telescopic rod 302, preventing displacement due to external forces and facilitating use.

[0030] In order to achieve a quick connection between the optical mounting plate 5 and the ball hinge 4, the connection mechanism 7 includes a connecting rod 702 fixedly connected to the surface of the ball hinge 4, a connecting seat 701 threadedly connected to the surface of the connecting rod 702, the connecting seat 701 fixedly connected to the bottom of the optical mounting plate 5, and a threaded hole 703 corresponding to the size of the connecting rod 702 is opened at the bottom of the connecting seat 701.

[0031] To adjust the horizontal position of the optical mounting plate 5, the adjustment mechanism 6 includes a first slide groove 601 formed on the top of the base 1, a first lead screw 602 rotatably connected within the first slide groove 601, a first motor 603 fixedly mounted on one side of the base 1, the output shaft of the first motor 603 fixedly connected to the first lead screw 602, and a first slider 604 slidably connected within the first slide groove 601, the first slider 604 being threadedly connected to the first lead screw 602. The first motor 603 drives the first lead screw 602 to rotate, thereby causing the first slider 604 to move along the first slide groove 601. A second motor 607 drives the second lead screw 606 to rotate, thereby causing the second slider 608 to move along the adjustment seat 605, thus adjusting the position of the optical mounting plate 5.

[0032] To lock the positions of the first slider 604 and the second slider 608 and prevent displacement due to external forces, the adjustment mechanism 6 also includes an adjustment seat 605 fixedly connected to the top of the first slider 604. A second motor 607 is fixedly mounted on one side of the adjustment seat 605, and a second lead screw 606 rotatably connected to the output shaft of the second motor 607 is fixedly connected to the output shaft of the second motor 607. A second slider 608 is slidably connected to the adjustment seat 605 and threadedly connected to the second lead screw 606. Magnetic damping blocks 609 are fixedly connected to both sides of the second slider 608 and the first slider 604. When the magnetic damping blocks 609 are energized, they limit the positions of the second slider 608 and the first slider 604. This is existing technology and will not be described in detail.

[0033] In order to adjust the height of the optical mounting plate 5, the ball bar support mechanism 3 includes a fixed rod 301 fixedly connected to the top of the second slider 608, a telescopic rod 302 slidably connected inside the fixed rod 301, and a ball hinge 4 fixedly connected to the top of the telescopic rod 302.

[0034] In order to limit the height of the telescopic rod 302 and ensure the stability of the telescopic rod 302 during extension and retraction, the ball bar support mechanism 3 also includes a positioning groove 303 opened in the inner wall of the fixed rod 301. A positioning block 304 is slidably connected in the positioning groove 303. The positioning blocks 304 are symmetrically arranged on the surface of the telescopic rod 302. A positioning rod 305 is symmetrically arranged in the upper part of the fixed rod 301. Two arc-shaped brake pads 306 are slidably connected on the positioning rod 305. A tension spring 307 is symmetrically arranged between the two arc-shaped brake pads 306.

[0035] In order to fix the rotation angle of the ball hinge 4, a piezoelectric ceramic brake pad (existing technology) is fixedly connected inside the ball hinge 4, and a control switch corresponding to the piezoelectric ceramic brake pad and the magnetic damping block 609 is fixedly connected on the base 1.

[0036] In summary, the multi-degree-of-freedom optical support adjustment mechanism for a ball bar provided in this embodiment has the following advantages: An adjustment mechanism 6 is provided, which drives the first lead screw 602 to rotate via the first motor 603, thereby causing the first slider 604 to move along the first slide groove 601. The second lead screw 606 is rotated via the second motor 607, thereby causing the second slider 608 to move along the adjustment seat 605, thus adjusting the position of the optical mounting plate 5. The angle of the optical mounting plate 5 is adjusted via the ball joint 4, and the height of the optical mounting plate 5 is adjusted by pulling the telescopic rod 302. The positions of the first slider 604 and the second slider 608 are locked by the magnetic damping block 609, and the height of the telescopic rod 302 is locked by the cooperation of the arc-shaped brake plate 306 and the tension spring 307, preventing displacement due to external forces and facilitating use.

[0037] In use, the base 1 is fixed to the worktable by the suction cup 2. The first motor 603 drives the first lead screw 602 to rotate, thereby causing the first slider 604 to move along the first slide groove 601. The second motor 607 drives the second lead screw 606 to rotate, thereby causing the second slider 608 to move along the adjusting seat 605, thus adjusting the position of the optical mounting plate 5. Extending the telescopic rod 302 and moving the ball hinge 4 to the target pitch angle, pressing the control switch, the magnetic damping block 609 locks the slide rail, and the piezoelectric ceramic sheet expands to press the gap of the ball hinge 4, preventing movement due to external forces. The optical mounting plate 5 can be adjusted with multiple degrees of freedom for ease of use.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
