Description
Technical Field
[0001] The present invention belongs to the technical field of optical axis adjustment equipment, and in particular relates to a flippable simple optical axis adjustment device for a multi-optical axis system. Background Art
[0002] In multi-axis systems, optical axis calibration is a critical step in ensuring stable system performance. For existing multi-axis systems, parallelism between optical axes is typically measured using a collimator, and the angles of each optical component are adjusted to achieve the predetermined parallelism requirement. During this process, for "I"-type double-layer fixed or "mouth"-type multi-layer fixed multi-axis systems, the system needs to be flipped and compared multiple times in order to calibrate the optical axis of the inverted optical system. However, existing optical axis calibration devices are unable to achieve a flipping function. Flipping requires removing standard parts (screws), disconnecting the rigid connection between the multi-axis system and the calibration device, and then manually flipping the system. Standard parts (screws) are then used to rigidly connect the product to be tested to the calibration device. The inconvenience of frequent manual flipping and comparison results in low calibration efficiency. Furthermore, some heavy multi-axis systems are difficult to flip manually, and there is a risk of the system falling and being damaged due to human error. Summary of the Invention
[0003] In response to the above problems, the purpose of the present invention is to provide a simple flippable optical axis adjustment device for a multi-axis system, aiming to solve the problem that the existing adjustment device cannot be flipped and to improve the efficiency of optical axis parallelism adjustment in a complex multi-axis system.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to design a flip-type simple optical axis adjustment device for a multi-optical axis system, including a base, a multi-porous support frame, a flip locking mechanism and a leveling bubble mechanism; the base is "U"-shaped, and the multi-porous support frame is respectively arranged on the inner sides of the two top edges of the base, the multi-porous support frame is strip-shaped, and a number of waist-shaped holes are evenly opened on the multi-porous support frame. The middle side of the multi-porous support frame is processed with a rotating shaft structure, and mounting holes are opened at the two top edges of the base. Bearings are also installed in the mounting holes, and the rotating shaft is inserted into the bearing, and the bearing is fixed with an elastic retaining ring. The multi-porous support frame and the base are rotatably connected through the rotating shaft and the bearing, and the flip locking mechanism is arranged between the base and the multi-porous support frame; the leveling bubble mechanism is arranged on the outer side of the top of the base.
[0005] Furthermore, the flip locking mechanism includes a locking knob, a spring, a locking shaft, a limit block, and a locking fixing seat. The locking fixing seat is fixed on the base, the locking knob is connected and fixed to the locking shaft, the limit block is fixed on the locking shaft, the locking fixing seat is provided with a limit hole adapted to the limit block, and the spring is provided between the locking knob and the locking fixing seat; the side of the porous support frame is provided with a locking hole matching the locking shaft.
[0006] Furthermore, the end of the locking shaft is tapered.
[0007] Furthermore, the limiting hole is a "Z"-shaped cam structure.
[0008] Furthermore, the leveling bubble mechanism includes: a bubble, a bubble fixing seat, a bubble fixing screw, a second spring, an adjustment fixing seat, a bubble adjusting screw I, and a bubble adjusting screw II; the leveling bubble mechanism is installed on the outer side of the top of the base through the bubble fixing screw and the bubble adjusting screw I; the bubble fixing seat and the adjustment fixing seat are connected through the bubble adjusting screw II, in which the second spring is provided; the horizontal direction of the bubble is adjusted by adjusting the preload force between the bubble adjusting screw II and the second spring.
[0009] In the present invention, the base is used to support the entire adjustment device, is formed in one piece, and has high stability and strength.
[0010] The multi-hole support frame is used to hold the multi-axis system to be adjusted. The multi-hole support frame is integrally manufactured with the rotating axis. Design and machining precision ensure consistency of the rotating axis system, ensuring a stable and reliable flipping process, enabling the multi-hole support frame to flip. A series of waist-shaped holes allows for adjustment of multi-axis systems of varying sizes, enhancing the versatility of the device.
[0011] Flip Locking Mechanism: Installed on the porous support frame and the base, it is used to lock the porous support frame. The flip locking mechanism includes a locking knob, spring, locking shaft, limit block, and locking mount. This mechanism utilizes a spring reset function, and the locking function can be achieved by rotating the locking knob. The tapered structure at the porous support frame and the end of the locking shaft improves the accuracy of the locking position and the reliability of the locking. Furthermore, the "Z"-shaped cam structure of the locking mount allows for locking by rotating the locking knob, ensuring reliable locking and enhancing the portability of the locking operation.
[0012] Leveling bubble mechanism: When adjusting optical equipment such as tilt, it is necessary to ensure that the optical axis adjustment device itself is level. To facilitate tilt adjustment or verification of optical equipment such as tilt, a leveling bubble mechanism is installed. This leveling bubble mechanism allows the horizontality of the multi-optical axis system and the platform to be observed, ensuring accuracy during optical axis adjustment. This allows the multi-optical axis system to be relatively level on different platforms. The leveling bubble of this device utilizes the preload of a spring to achieve bubble adjustment, allowing for a wide adjustable range. Its primary purpose is to ensure that when the flip adjustment device is used to adjust the optical axis consistency of the multi-optical axis system, the multi-optical axis system is aligned with the reference, thereby achieving accurate optical axis adjustment.
[0013] The present invention relates to a simple and flippable optical axis adjustment device for a multi-axis system. The device mainly includes a base, a multi-hole support frame, a flip locking mechanism, and a leveling bubble mechanism; wherein the multi-hole support frame and the rotating shaft are integrally processed to realize the rapid flipping of the multi-axis system, and the waist-shaped holes can be used to adapt to the adjustment of multi-axis systems of different sizes; the flip locking mechanism is used to lock and fix the multi-axis system after the flipping is completed, thereby ensuring the stability of the multi-axis system during optical axis adjustment; the leveling bubble mechanism can be used to ensure the horizontality of the device during optical axis adjustment, thereby ensuring the accuracy of optical axis adjustment. The present invention has a simple structure, strong versatility, and is easy to operate.
