[0024] The following combination Figure 1 The specific structure and working process of the large-caliber tooling level adjustment device of the present invention are described.

[0025] One embodiment of the present invention provides a large-caliber tooling level adjustment device, see Figure 1 As shown, the leveling device includes a parallel light source 1, a hub supporting tooling, a supporting hub 2, a plane flat crystal 3, a horizontal guide rail 4, a reflecting prism 5 and an autocollimator 6. The parallel light source 1 is used to output a parallel light beam upward; the hub supporting tooling is used to install the supporting hub 2, and the supporting hub 2 is suitable for posture adjustment on the hub supporting tooling, and a plane flat crystal 3 is set on the supporting hub 2; the horizontal guide rail 4 is set above the parallel light source 1 and the supporting hub 2; the reflecting prism 5 is movably set on the horizontal guide rail 4, and is suitable for position conversion between various working positions. The working positions of the reflecting prism 5 include a first position and a second position, the first position is directly above the parallel light source 1, and the second position is directly above the plane flat crystal 3; the outgoing light beam of the reflecting prism 5 maintains a 90° angle with the incident light beam; the autocollimator 6 is installed on the horizontal guide rail 4, and the outlet end of the autocollimator 6 is set toward the reflecting prism 5.

[0026] It is understood that this embodiment of the large-aperture tooling leveling device, by constructing a device that adjusts the position of the support hub 2 based on the light output direction of the parallel light source 1, ensures that the axis of the support hub 2 is parallel to the optical axis of the focusing lens to be assembled, providing a hardware foundation for the installation and adjustment of the focusing lens. This embodiment of the large-aperture tooling leveling device has high testing accuracy, can complete the leveling of the support hub 2 through simple calibration and adjustment, and is lightweight, stable, and easy to operate.

[0027] Specifically, the parallel light source 1 outputs a parallel light beam upward, which is deflected at the first position by the reflective prism 5 to form a light spot on the autocollimator 6. The reflective prism 5 is then moved to the second position, and the light emitted by the autocollimator 6 is reflected by the reflective prism 5 and the plane flat crystal 3 to form a crosshair on the autocollimator 6. Based on the drift of the crosshairs relative to the light spot, the support hub 2 is controlled to adjust its posture so that the formed crosshairs coincide with the light spot, indicating that the axis of the support hub 2 in this direction is consistent with the light emitting direction of the parallel light source 1. The horizontal guide rail 4 is adjusted to rotate horizontally by a certain angle, and the above-mentioned posture adjustment of the support hub 2 is performed in the second direction. The two directions are iteratively adjusted repeatedly until the crosshairs and the light spot coincide in both directions, thus completing the leveling of the support hub 2 plane.

[0028] In some embodiments of the large-aperture tooling horizontal adjustment device of the present invention, the large-aperture tooling horizontal adjustment device also includes a plumb line 7, which is located below the horizontal guide rail 4. The working position of the reflecting prism 5 also includes a third position, which is directly above the plumb line 7.

[0029] It can be understood that the plumb line 7 of this embodiment can be used to calibrate the light output direction of the parallel light source 1. The plumb line 7 outputs a vertically upward light beam. The posture of the horizontal guide rail 4 is adjusted according to the direction of the light beam output by the plumb line 7, so that the light output direction of the autocollimator 6 is perpendicular to the plumb line 7, and then the horizontal orientation of the autocollimator 6 is determined. On this basis, the light output direction of the parallel light source 1 is calibrated and adjusted so that the light output direction of the parallel light source 1 is consistent with that of the plumb line 7, and the parallel light source 1 can obtain parallel light output vertically upward.

[0030] Specifically, in some specific examples of the large-caliber tooling level adjustment device of the present invention, continue to refer to Figure 1 As shown, a lifting platform 8 is connected to each end of the horizontal guide rail 4, and the horizontal guide rail 4 is suitable for posture adjustment on the lifting platform 8. The lifting platform 8 includes a vertical lifting mechanism and a horizontal rotation mechanism. The vertical lifting mechanism is suitable for adjusting the height of the two ends of the horizontal guide rail 4, and the horizontal rotation mechanism is suitable for adjusting the horizontal guide rail 4 in the horizontal direction. The parallel light source 1 is movably mounted on an adjustment base 9, and the parallel light source 1 is suitable for posture adjustment on the adjustment base 9.

[0031] It is understood that the lifting platforms 8 at both ends of the horizontal guide rail 4 are used to adjust the posture of the horizontal guide rail 4. Its vertical lifting mechanism is used to adjust the height of the two ends of the horizontal guide rail 4, which can assist in calibrating the light output direction of the parallel light source 1. Its horizontal rotation mechanism is used to adjust the horizontal orientation of the horizontal guide rail 4 to achieve leveling of the support hub 2 in at least two directions. The adjustment base 9 is used to adjust the light output direction of the parallel light source 1, and cooperates with the plumb line 7 to ensure that the parallel light source 1 outputs vertically upward parallel light.

[0032] It should be understood that the lifting platform 8 in this example includes a vertical lifting mechanism and a horizontal rotation mechanism. The specific structures of the vertical lifting mechanism and the horizontal rotation mechanism are not the protection points of the present invention. Existing adjustment mechanisms can be used to achieve the vertical lifting and horizontal rotation functions. For example, the vertical lifting mechanism can use a folding lifting frame, and the horizontal rotation mechanism can be achieved by mounting the folding lifting frame horizontally on a rotating guide rail, or by directly designing a torsion structure for the folding lifting frame to achieve horizontal rotation. In this example, the posture adjustment of the horizontal guide rail 4 is achieved by designing the lifting platform 8 into a structure that can adjust the lifting and horizontal rotation of the two ends of the horizontal guide rail 4.

[0033] In some embodiments of the large-aperture tooling horizontal adjustment device of the present invention, a motorized slider is provided on the horizontal guide rail 4, and a reflective prism 5 is fixed on the motorized slider. The motorized slider is adapted to drive the reflective prism 5 to move on the horizontal guide rail 4. The reflective prism 5 is a pentaprism. When the pentaprism is in a first position, a vertical beam steering is formed between the parallel light source 1 and the autocollimator 6. When the pentaprism is in a second position, a vertical beam steering is formed between the plane flat crystal 3 and the autocollimator 6. When the pentaprism is in a third position, a vertical beam steering is formed between the plummet 7 and the autocollimator 6.

[0034] It can be understood that the electric slider in this embodiment is installed on the horizontal guide rail 4 and fixes the reflective prism 5. The electric slider can accurately control the position of the reflective prism 5. The electric slider drives the pentaprism to move on the horizontal guide rail 4 and can automatically switch between different working positions, thereby improving the convenience and accuracy of operation.

[0035] A pentaprism is an optical element that can redirect an incident light beam at a 90-degree angle. In this embodiment, the pentaprism has three key positions: First, it is located directly above the parallel light source 1. It forms a vertical beam deflection between the parallel light source 1 and the autocollimator 6. The pentaprism deflects the parallel light beam emitted by the parallel light source 1 toward the autocollimator 6, forming a light spot. Second, it is located directly above the plane crystal 3. It deflects the light emitted by the autocollimator 6 toward the plane crystal 3. The plane crystal 3 then reflects the light back to the autocollimator 6, forming a crosshair. The position of the support hub 2 is adjusted based on the drift of the crosshairs relative to the light spot until the two overlap. Third, it is located directly above the plumb line 7. It forms a vertical beam deflection between the plumb line 7 and the autocollimator 6. The pentaprism deflects the vertical upward light beam emitted by the plumb line 7 toward the autocollimator 6, which is used to further calibrate and verify the verticality of the system.

[0036] When the pentaprism is switched between the first position and the third position, it is used to calibrate the verticality of the light output direction of the parallel light source 1. In the third position, the pentaprism uses the plumb line 7 to output a vertically upward light beam to ensure that the reference direction of the entire system is correct. The height of the two ends of the horizontal guide rail 4 is adjusted by the lifting platform 8 to achieve fine leveling of the horizontal guide rail 4, so that the light output direction of the autocollimator 6 is perpendicular to the light beam of the plumb line 7, thereby determining the horizontal orientation of the autocollimator 6. When the pentaprism is in the first position, the light output direction of the parallel light source 1 is adjusted by adjusting the base 9. By comparing the display on the autocollimator 6 with the direction of the plumb line 7, it is ensured that the parallel light source 1 outputs a vertically upward parallel light beam.

[0037] When the pentaprism switches between the first and second positions, it is used to adjust the posture of the support hub 2. In the first position, the parallel light source 1 outputs a parallel light beam upward, which is deflected by the pentaprism in the first position, forming a cross light spot on the autocollimator 6, providing a stable reference for calibration and adjustment. When the pentaprism is moved to the second position, the light emitted by the autocollimator 6 is reflected by the pentaprism and the flat crystal 3 and then returned to the autocollimator 6, forming a crosshair. The posture of the support hub 2 is adjusted according to the drift of the crosshairs relative to the light spot until the two coincide, indicating that the axis of the support hub 2 is consistent with the light output direction of the parallel light source 1. By horizontally rotating the horizontal guide rail 4, the above process is repeated in the other direction, and iterative adjustments are made until the ideal alignment is achieved in both directions, completing the leveling of the support hub 2.

[0038] In some embodiments of the large-diameter tooling level adjustment device of the present invention, the support hub 2 is located 1.5m to 2m above the ground, a light source exit well is provided on the ground, the parallel light source 1 is provided in the light source exit well, the depth of the light source exit well is 1m, and the light outlet of the light source exit well is located 0.5m above the ground.

[0039] This embodiment further optimizes the spatial layout and operational convenience of the entire horizontal adjustment device through the position of the support hub 2 and the design of the light source light exit well. The support hub 2 is located 1.5 meters to 2 meters above the ground. This height design facilitates adjustments and maintenance work by operators, while ensuring a reasonable spacing between optical components to avoid mutual interference. The depth of the light source light exit well is 1 meter, which helps to reduce the impact of the external environment on the parallel light source 1, such as preventing dust or other debris from entering the light source area, thereby ensuring the quality of the light beam. The light outlet of the light source light exit well is located 0.5 meters above the ground. This design enables the parallel light source 1 to emit a parallel light beam upward, which is deflected by the reflective prism 5 and eventually reaches the autocollimator 6 and other optical components.

[0040] On the other hand, the present invention also provides an alignment detection method for a large-diameter tooling horizontal adjustment device, which is applicable to the large-diameter tooling horizontal adjustment device in any one of the above-mentioned embodiments or examples. The alignment detection method for the large-diameter tooling horizontal adjustment device provided by the present invention is described below. The alignment detection method for the large-diameter tooling horizontal adjustment device described below can be referenced to the large-diameter tooling horizontal adjustment device described above.

[0041] In some specific embodiments, the alignment detection method of the large-aperture tooling level adjustment device of the present invention includes vertical calibration of the light emitting direction of the parallel light source 1, posture leveling of the support hub 2 in the first direction, posture leveling of the support hub 2 in the second direction, and iterative optimization of the first direction and the second direction.

[0042] The vertical calibration of the light emitting direction of the parallel light source 1 is performed using a plumb line 7. The moving reflective prism 5 is positioned in the third position directly above the plumb line 7. The plumb line 7 is used for initial calibration to ensure that the system's reference direction is correct. The height of the two ends of the horizontal guide rail 4 is adjusted using a lifting platform 8 so that the light emitting directions of the plumb line 7 and the autocollimator 6 are perpendicular. Keeping the height of the horizontal guide rail 4 unchanged, the moving reflective prism 5 is positioned in the first position directly above the parallel light source 1. The posture of the parallel light source 1 is adjusted by adjusting the base 9 so that the light emitting direction of the parallel light source 1 is consistent with that of the plumb line 7, completing the vertical calibration of the light emitting direction of the parallel light source 1.

[0043] The process of leveling the posture of the support hub 2 in the first direction includes: adjusting the horizontal guide rail 4 horizontally toward the first direction, moving the reflective prism 5 to a first position directly above the parallel light source 1, and redirecting the light beam emitted by the parallel light source 1 through the reflective prism 5 to form a first light spot on the autocollimator 6. Moving the reflective prism 5 to a second position directly above the plane crystal 3, the light emitted by the autocollimator 6 is sequentially reflected by the reflective prism 5, the plane crystal 3, and the reflective prism 5, forming a first crosshair on the autocollimator 6. Based on the drift of the first crosshairs relative to the first light spot, the posture of the support hub 2 in the first direction is adjusted so that the first crosshairs coincide with the first light spot, thereby achieving the leveling of the posture of the support hub 2 in the first direction.

[0044] The posture leveling process of the support hub 2 in the second direction includes: horizontally rotating the horizontal guide rail 4, adjusting the horizontal guide rail 4 to be horizontally toward the second direction, moving the reflecting prism 5 to the first position directly above the parallel light source 1, and the light beam emitted by the parallel light source 1 is deflected by the reflecting prism 5 to form a second light spot on the autocollimator 6; moving the reflecting prism 5 to the second position directly above the plane crystal 3, and the light emitted by the autocollimator 6 is reflected by the reflecting prism 5, the plane crystal 3 and the reflecting prism 5 in turn, and a second cross hair is formed on the autocollimator 6. Based on the drift amount of the second cross hair relative to the second light spot, the posture of the support hub 2 in the second direction is adjusted so that the second cross hair coincides with the second light spot, thereby forming the posture leveling of the support hub 2 in the second direction.

[0045] The iterative optimization process in the first direction and the second direction includes: repeatedly rotating the horizontal guide rail 4 in the first direction and the second direction, iteratively performing the above-mentioned posture leveling of the support hub 2 in the first direction and the posture leveling of the support hub 2 in the second direction, until the crosshairs and the light spots in the first direction and the second direction can coincide with each other at one time without adjustment, indicating that the posture adjustment position of the support hub 2 is qualified, and the leveling of the plane of the support hub 2 is completed.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
