[0035] Example 6 This embodiment is further elaborated on the basis of Embodiment 5. The drivers of the horizontal adjustment mechanism 2 and the multi-degree-of-freedom adjustment mechanism 4 are both servo motors with integrated position sensors. The transmission mechanisms of the horizontal adjustment mechanism 2 and the multi-degree-of-freedom adjustment mechanism 4 are self-locking when the servo motors are powered off.

[0036] The ground-supported omnidirectional high-precision rapid assembly and adjustment equipment for large-scale precision optical systems provided by the present invention has the following main innovations: 1. The installation and adjustment equipment adopts ground support to avoid the system errors and poor stability introduced by the traditional lifting method.

[0037] In the installation and adjustment of large optical systems, the traditional hoisting method generally requires one crane operator and three to four ground operators to work together. Special installation and adjustment equipment is needed to limit the azimuth disturbance caused by the hoisting. The installation and adjustment process is time-consuming, labor-intensive and inefficient.

[0038] The present invention adopts a ground support method, with the support base plate 1, the longitudinal horizontal adjustment plate 22, the transverse horizontal adjustment plate 26, the azimuth adjustment plate 32, and the support plate 41 stacked in sequence, with a compact space, and the structural support parts are all made of steel, with excellent supporting capacity. The installation and adjustment equipment is designed with a horizontal adjustment mechanism 2, an azimuth adjustment mechanism 3, and a multi-degree-of-freedom adjustment mechanism 4. After the large-scale precision system is initially adjusted and aligned and placed on the installation and adjustment equipment, each adjustment mechanism can be independently controlled to improve the stability, quality, and efficiency of the installation and adjustment process.

[0039] 2. It is equipped with a horizontal adjustment mechanism 2, an azimuth adjustment mechanism 3 and a multi-degree-of-freedom adjustment mechanism 4, which can complete omnidirectional high-precision adjustment of large optical equipment.

[0040] The present invention is provided with a horizontal adjustment mechanism 2, an azimuth adjustment mechanism 3 and a multi-degree-of-freedom adjustment mechanism 4. The components of the horizontal adjustment mechanism include a horizontal horizontal adjustment plate, a vertical horizontal adjustment plate, a servo motor and a transmission screw. The motor can be controlled to drive the screw to rotate to adjust the movement of the support plate in two degrees of freedom in the horizontal plane. The horizontal and vertical adjustment plates can be adjusted within a range of ±200mm and an adjustment precision of ±0.1mm. The azimuth adjustment plate of the azimuth adjustment mechanism 3 can realize the rotation of the azimuth angle, with a rotation adjustment range of ±10° and an adjustment precision of 0.01°. The servo motor of the multi-degree-of-freedom adjustment mechanism 4 controls the turbine screw to drive the support plate, and the support plate is controlled by four sets of independent drive systems, with a height adjustment stroke of ±40mm and an adjustment precision of ±0.1mm. The four lifting adjustment components can make the horizontal plane angle adjustment stroke reach ±3° and an adjustment precision of 10″. The horizontal adjustment mechanism 2, the azimuth adjustment mechanism 3 and the multi-degree-of-freedom adjustment mechanism 4 can enable the installed equipment to complete the adjustment movement within a certain stroke of 6 degrees of freedom in space, and have the characteristics of multiple degrees of freedom, high precision, good installation stability and strong adaptability.

[0041] 3. The multi-degree-of-freedom adjustment mechanism adopts four-point drive to achieve high-precision adjustment movement of the device in complex environments, and has the characteristics of high adaptability.

[0042] Another innovation of the present invention is that the multi-degree-of-freedom adjustment mechanism adopts a four-point drive scheme, and realizes omnidirectional high-precision adjustment of the spatial position of the lifting support plate through a conversion matrix. The four worm screws are driven by four servo motors, which are independent of each other and distributed at the four corners of the lifting support plate. Mutual independence means that each drive motor can be independently controlled, and flexible and sensitive coordinated adjustment can be completed during the installation and adjustment process, which also makes the installation and adjustment equipment more widely applicable and leaves more margin for the initial adjustment of the equipment. The introduced conversion matrix improves the accuracy and sensitivity of the installation and adjustment. With the center of the support plate as the origin, the position coordinate values ​​of the four lifting mechanisms can be obtained. The rotation angles and values ​​of the pitch axis (x-axis) and the azimuth axis (y-axis) are set during the installation and adjustment process. Using the conversion R in the geometric transformation, the target values ​​of the four-point coordinate positions can be obtained. Based on this difference, the motor can be operated to complete the fine adjustment movement of the spatial position of the lifting plate. This design can improve the system stability of the installation and adjustment process of various large optical equipment, especially in applications that require precise alignment of the optical axis.

[0043] In the present invention, the lifting and adjusting assembly four-point driving support plate to adjust includes: Taking the center of the support plate as the origin, obtain the coordinate values ​​of the four points of the four lifting adjustment components on the support plate ( a 1. a 2. a 3. a 4); In the process of assembling and adjusting large-scale precision optical equipment, the rotation angles and values ​​of the pitch axis and azimuth axis are set, and the conversion matrix in the geometric transformation is used to obtain the target values ​​of the four-point coordinate positions. The four lifting and adjustment components are controlled to drive the support plate according to the difference between the target values ​​of the four-point coordinate positions and the coordinate values ​​of the four-point positions to perform fine adjustment movements of the spatial position.

[0044] In the present invention, the four-point support transformation matrix is ​​a rotation matrix and Euler angle formula.

[0045] 4. The servo motor is used as the driver, and the screw and worm screw are used as the transmission mechanism to achieve power-off self-locking, which has the advantage of low cost.

[0046] The present invention drives the screw and the turbine screw mechanism through a servo motor with an integrated high-precision position sensor, ensuring accurate, closed-loop control of the entire system; one end of the optimized transmission mechanism is connected to the plate and the other end is connected to the motor output shaft, converting the rotation of the motor into linear motion, with the characteristics of high transmission rate, low maintenance cost, and power-off in-situ self-locking. The entire set of adjustment mechanisms can not only ensure the stability of the equipment, but also have excellent load-bearing capacity. The adjustment mechanism can achieve self-locking in the power-off state, which also means that when unexpected conditions such as power outages occur, the adjusted equipment can maintain the current adjustment state. The servo motor integrates a high-precision position sensor, which means that the entire system does not need to install additional sensors. This design ensures the safety and stability of the adjustment and has the advantage of low cost.

[0047] In order to better understand the present invention, a complete description of the working principle of the present invention is given below: First, the present invention is stably placed on a reference plane and adjusted to a suitable posture, and then the adjusted device is placed on the platform of the present invention and fixed with bolts, at which point the coarse adjustment process is completed; the horizontal adjustment mechanism 2 is controlled to adjust the transverse and longitudinal adjustment plates of the installation and adjustment device so that the optical axis of the adjusted device is close to the reference axis end, and the azimuth adjustment mechanism 3 and the multi-degree-of-freedom adjustment mechanism 4 are used to fine-tune the adjusted device, and the detection equipment is used to determine whether the optical axis, angle and other indicators are met, thereby realizing the integrated installation and docking of large optical systems.

[0048] The present invention can achieve the following functions: Able to realize stable and safe ground-supported installation and adjustment operations; Possessing omnidirectional high-precision adjustment function in space; With power-off original position mechanical self-locking function; The horizontal direction (XY direction) adjustment range is ±200mm, the height adjustment range is ±40mm, and the adjustment accuracy is ±0.1mm; The horizontal plane rotation adjustment range is ±10°, and the adjustment accuracy is 0.01°; the horizontal plane angle adjustment range reaches ±3°, and the adjustment accuracy is 10″.

[0049] It has a compact structure and a large adjustable range, and can flexibly adapt to various usage requirements.

[0050] Taking into account the practicality of the equipment and space limitations, the horizontal adjustable rotation angle of the device is relatively small, but for large precision optical equipment, after the initial alignment and placement process, the actual adjustable angle of the present invention usually meets the use requirements.

[0051] The above is a specific description of the implementation mode of the present invention, but the present invention is not limited to the described embodiments.
