Description

Technical Field

[0001] This invention belongs to the field of mechanical manufacturing testing technology, specifically relating to an installation and adjustment method for a rotating body shaft bore diameter measuring device and an auxiliary adjustment device. Background Technology

[0002] Rotating components and rotating shafts (collectively referred to as rotating bodies in this invention) with structures such as rings, cylinders, and tubes are commonly used parts in engineering machinery. In the field of precision machining, it is necessary to know the diameter (or radius, collectively referred to as shaft / hole diameter) of their outer or inner circles in real time.

[0003] Synchronous multi-directional laser ranging by integrating multiple (three or more) laser rangefinders in the same plane can achieve online, fast, and accurate measurement of the axis / aperture of a rotating body. However, when multiple laser rangefinders of this measuring device are integrated and installed, the laser measurement direction must be in the same plane. In particular, some of these measuring devices require the included angle between adjacent laser rangefinders to be a certain value, and / or the beams (measurement direction or its reverse extension) to intersect at a point. Special installation and adjustment methods and auxiliary tools are required, which are currently lacking. Summary of the Invention

[0004] To address the above problems, this invention designs an installation and adjustment method for a rotary shaft bore diameter measuring device and an auxiliary adjustment device. Through a double-ring calibrator, precise adjustment of the rotary shaft / bore diameter (including inner and outer diameter) measuring device can be achieved.

[0005] This invention discloses an installation and adjustment method for a rotating shaft / aperture measuring device, characterized by the configuration of a double-ring calibration component (also known as an auxiliary adjustment device or adjustment component, which can be designed or ordered). The double rings include an outer ring (B1) and an inner ring (B2). According to the original design angle requirements of the laser rangefinder in the shaft / aperture measuring device, corresponding beam through-holes (B3) are respectively set in the inner and outer rings of the calibration component. The diameter of the beam through-hole is not greater than the laser rangefinder spot diameter (not considering spot dispersion caused by air scattering, but it cannot be too small to avoid interference or diffraction effects). The double rings of the calibration component are fixedly connected, and the connection structure (B4) should be designed to avoid blocking the light from the beam through-hole and the placement of the measuring device during installation and adjustment. The shaft / aperture measuring device includes an inner diameter measuring device and / or an outer diameter measuring device.

[0006] Adjustment method for inner diameter measuring device: Place the inner diameter measuring device at the center of the inner ring of the calibration component. It does not need to be very precise, but the more precise the better. Adjust the installation position of the laser rangefinder so that the light emitted by each laser rangefinder is emitted from the beam through-holes at corresponding angles of the inner and outer rings at the same time. The diffused light spots should be evenly distributed around the beam through-holes on the inner and outer surfaces of the inner and outer rings. At this time, it is considered that the installation direction of the laser rangefinder is adjusted in place.

[0007] Adjustment method for outer diameter measuring device: Place the calibration component at the center of the outer diameter measuring device. High precision is not required, but generally, the more precise the better. Adjust the installation position of the laser rangefinder so that the light emitted by each laser rangefinder is simultaneously directed from the beam apertures at corresponding angles of the inner and outer rings toward the center of the calibration component. The diffused light spots should be evenly distributed around the beam apertures on the outer surface of the outer ring and the outer surface of the inner ring. At this point, the installation direction of the laser rangefinder is considered to be properly adjusted.

[0008] Furthermore, the inner surface of the inner ring of the calibration component is provided with fine inner scribe lines for flatness adjustment, and the inner scribe lines pass through the center of the inner circumference of all inner ring beam through holes; the outer surface of the outer ring of the calibration component is provided with fine outer scribe lines for flatness adjustment, and the outer scribe lines pass through the center of the outer circumference of all outer ring beam through holes; the scribe lines are fine scribe lines, and the line width is generally no more than 0.5 mm.

[0009] Furthermore, the adjustment method also includes first adjusting the flatness of the emitted light beam, and then adjusting the emission direction within the plane.

[0010] Furthermore, after adjustment using the aforementioned double-ring calibration component, the included angles between each laser rangefinder are quantitatively calibrated through calibration. If the calibration result does not meet the requirements, the fine-tuning mechanism of the corresponding laser rangefinder is finely adjusted again according to the deviation, and then calibrated again, repeating the process until the requirements are met.

[0011] Furthermore, the calibration component has four beam through holes at 90° intervals on the inner and outer rings respectively.

[0012] Furthermore, the calibration element has three beam through holes at 120° intervals on the inner and outer rings respectively.

[0013] Furthermore, the calibration component has 12 beam through holes at 30° intervals on the inner and outer rings respectively.

[0014] Furthermore, the calibration element has 24 beam through holes at 15° intervals on the inner and outer rings respectively.

[0015] Furthermore, when installing and adjusting the outer diameter measuring device, a light spot observation ring or observation cylinder is set on the inner side of the inner ring; when adjusting the inner diameter measuring device, a light spot observation ring or observation plate is set on the outer side of the outer ring; the above settings make it easier to observe and adjust the position of the light spot.

[0016] Furthermore, for the calibration component used for the installation and adjustment of the outer diameter measuring device, corresponding marks are set on the outer surface of the observation ring or observation cylinder at the position corresponding to the beam through hole. The marks include dot marks, asterisk marks, + marks or x marks, etc., to facilitate the determination of the center position of the light spot.

[0017] Furthermore, in the calibration component used for installing and adjusting the outer diameter measuring device, the observation ring or observation cylinder is fixedly connected to the inner ring of the calibration component.

[0018] Furthermore, the inner surface of the observation ring or observation plate of the calibration component used for the installation and adjustment of the inner diameter measuring device is marked with corresponding positions corresponding to the beam through hole. The marks include dot marks, asterisk marks, + marks or x marks, etc., which facilitate the determination of the center position of the light spot.

[0019] Furthermore, a calibration component for installing and adjusting the inner diameter measuring device, wherein the observation ring or observation plate is fixedly connected to the outer ring of the calibration component.

[0020] On the other hand, an auxiliary adjustment device for a rotating shaft / aperture measuring device is characterized by comprising a coplanar double-ring structure, wherein the double rings include an outer ring (B1) and an inner ring (B2). According to the original design angle requirements of the laser rangefinder in the laser diameter measuring device, corresponding beam apertures (B3) are respectively set in the inner ring and the outer ring. The diameter of the beam aperture is not greater than the spot diameter of the laser rangefinder. The double rings are fixedly connected, and the connection structure (B4) is designed to avoid blocking the light from the beam aperture.

[0021] Furthermore, the inner surface of the inner ring is provided with a fine inner etched line for flatness adjustment, and the inner etched line passes through the center of the inner circumference of all inner ring beam through holes; the outer surface of the outer ring is provided with a fine outer etched line for flatness adjustment, and the outer etched line passes through the center of the outer circumference of all outer ring beam through holes; the etched lines are fine etched lines, and the line width generally does not exceed 0.5 mm.

[0022] Furthermore, a light spot observation ring or observation cylinder is provided on the inner side of the inner ring; and / or a light spot observation ring or observation plate is provided on the outer side of the outer ring; the above arrangements make it easier to observe and adjust the position of the light spot.

[0023] The advantages and beneficial effects of this invention are as follows: The double-ring calibration component, also known as the auxiliary adjustment device, enables precise adjustment of the rotating shaft / aperture (including inner and outer diameter) measuring device. The auxiliary adjustment device mainly includes a double ring, a beam through-hole, and a scribing design, which is a common machining process for current high-precision machining technology. Furthermore, the adjustment process avoids the mutual influence between different laser rangefinders and the mutual influence between the horizontal and vertical adjustments of a single laser rangefinder. In summary, the auxiliary adjustment device of the rotating shaft / aperture measuring device of this invention is easy to manufacture and process, and the installation and adjustment method of the rotating shaft / aperture measuring device avoids the uncertainty of interactive cyclic adjustment caused by the interaction of multiple factors, resulting in high efficiency.

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0033] Example 1

[0034] This invention discloses an installation and adjustment method for a rotating shaft / aperture measuring device, which includes a double-ring calibration component (such as...). Figure 1 and Figure 2 As shown (design or customization is acceptable), the double ring includes an outer ring B1 and an inner ring B2. Based on the original design angle requirements of the laser rangefinder in the shaft / aperture measuring device, corresponding beam through-holes B3 are respectively set in the inner and outer rings of the calibration component. The diameter of the beam through-hole is not greater than the laser rangefinder spot diameter (ignoring spot dispersion caused by air scattering, but also not too small to avoid interference or diffraction effects). The double rings of the calibration component are fixedly connected. The connection structure B4 should be designed to avoid blocking the light from the beam through-hole and the placement of the measuring device during installation and adjustment. For example, an upper or lower U-shaped bracket can be used for bridging, or a planar connecting rod can be used for fixing. Figure 1 The diagram shows a planar connecting rod fixed connection;

[0035] The shaft / bore diameter measuring device includes an inner diameter measuring device and / or an outer diameter measuring device, respectively as follows: Figure 3 , Figure 4 As shown, multiple laser rangefinders are mounted on the cylindrical detection rod 13 or the ring-shaped part 8 respectively (the figure shows three laser rangefinders assembled at a 120-degree angle between each pair).

[0036] The internal diameter measuring device and its driving device calibrated in this embodiment are as follows: Figure 3 As shown: Three laser rangefinders 9 (only one is marked in the figure) are installed on the detection rod 13 at the same time, and the detection rod is installed on the support member 4 by means of clamp 14.

[0037] The calibration targets the outer diameter measuring device and its drive device, such as Figure 4 As shown: Three laser rangefinders 9 (only one is marked in the figure) are installed on the ring-shaped component 8 at the same time, and the ring-shaped component is fixedly connected to the support component 4.

[0038] The driving device includes a frame 1, guide rods 3, a first lead screw 10, and a first drive motor 5. A pair of vertically arranged guide rods 3 are provided on the frame 1. A first lead screw 10, rotatably mounted on the frame 1 between the pair of guide rods 3, is provided on the frame 1 between the guide rods 3. One end of the first lead screw 10 is connected to the drive shaft of the first drive motor 5. A support member 4 has a guide hole that slides with the guide rods 3, and a threaded hole that threads with the first lead screw 10. The support member 4 is positioned on the first lead screw 10 and the guide rods 3. The first drive motor 5 drives the support member 4 to move vertically along the guide rods 3. When the rotating body 11 is also vertically positioned, the laser rangefinder 9 can move along the axial direction of the workpiece being measured, enabling the laser rangefinder 9 to perform multi-point sampling on the workpiece.

[0039] To facilitate the movement of the workpiece to the testing position, a horizontally movable support platform 12 is further provided on the frame 1 below the support member 4. Specifically, the frame 1 is provided with a guide rail, and the bottom surface of the support platform 12 is provided with a corresponding guide groove that slides in cooperation with the guide rail. The frame 1 is also provided with a second lead screw arranged parallel to the guide rail. The bottom surface of the support platform 12 is threaded in cooperation with the second lead screw. A second drive motor 2 is provided on the frame 1 corresponding to one end of the second lead screw, and the second drive motor 2 is connected to one end of the second lead screw.

[0040] To enable automatic operation of the first drive motor 5 and the second drive motor 2, the detection device also includes a PLC controller 6. The display 7 is integrated with the PLC controller 6 and is located on one side of the frame 1. The PLC controller 6 is electrically connected to the laser rangefinder 9. The PLC controller 6 is electrically connected to the first drive motor 5 and the second drive motor 2 through a frequency converter. The PLC controller 6 can perform calculations on the measurement data at multiple points to reduce detection errors and avoid detection errors caused by errors in the roundness of the machining at different points.

[0041] Installing the laser rangefinder according to design requirements facilitates both calibration and measurement operations. Generally, the shaft / hole diameter measuring device will have pre-drilled mounting slots or holes on the mounting bracket (such as a ring bracket) to match the laser rangefinder's installation angle as required by the design. For applications with low precision requirements, no adjustment is needed; calibration can be performed directly after installation. When high-precision installation is required, the mounting slots or holes on the measuring device bracket are equipped with fine-tuning mechanisms to adjust the laser rangefinder's beam emission direction. In this case, a dedicated adjustment effect detection device and adjustment method are needed to achieve precise adjustment. In most cases, for shaft / hole diameter measuring devices requiring precise installation, the laser rangefinder is installed at a symmetrical angle of 120° or 90°, and the light rays intersect at a common point (either the emission directions intersect at one point or the backward extensions of the emission rays intersect at one point). Although the measuring device does not necessarily require the laser rangefinder light rays to intersect at one point, this design facilitates principle calculations, and operators can intuitively estimate the shaft / hole diameter through the measured distance values. On the other hand, this measuring device can also be used to verify the virtual center position of the measured rotating body, and it has an auxiliary role in the installation of other structures.

[0042] Adjustment method for inner diameter measuring device: Place the inner diameter measuring device at the center of the inner ring of the calibration component. It does not need to be very precise, but the more precise the better. Adjust the installation position of the laser rangefinder so that the light emitted by each laser rangefinder is emitted from the beam through-holes at corresponding angles of the inner and outer rings at the same time. The diffused light spots should be evenly distributed around the beam through-holes on the inner and outer surfaces of the inner and outer rings. At this time, it is considered that the installation direction of the laser rangefinder is adjusted in place.

[0043] Adjustment method for outer diameter measuring device: Place the calibration component at the center of the outer diameter measuring device. High precision is not required, but generally, the more precise the better. Adjust the installation position of the laser rangefinder so that the light emitted by each laser rangefinder is simultaneously directed from the beam apertures at corresponding angles of the inner and outer rings toward the center of the calibration component. The diffused light spots should be evenly distributed around the beam apertures on the outer surface of the outer ring and the outer surface of the inner ring. At this point, the installation direction of the laser rangefinder is considered to be properly adjusted.

[0044] Generally, for rotating shaft / aperture measuring devices, when precise adjustment of the laser rangefinder's direction is required, a fine-tuning mechanism is incorporated. This includes left-right and up-down fine-tuning mechanisms along the laser rangefinder's longitudinal direction (laser emission direction). Specific structures include threaded fine-tuning (such as...). Figure 5 (As shown) or ultra-thin shims for fine-tuning; the position of the ranging starting point (sometimes called the ranging origin) generally does not need fine-tuning and can be calibrated later. If adjustment is required, the position of the laser rangefinder can be adjusted by comparing the ranging values. Of course, the measuring device needs to be equipped with a fine-tuning structure for the installation position of the laser rangefinder, such as a forward or backward or left and right translation fine-tuning structure, etc.; for specific positioning methods, such as when adjusting the inner diameter measuring device, the measuring device can be set at the center of the standard double-ring calibration part, the direction can be adjusted to the correct position, and then the ranging values ​​of each laser rangefinder can be compared to see if they meet the design specifications. The adjustment method for the outer diameter measuring device is similar.

[0045] The installation and adjustment method of the rotating shaft / aperture measuring device designed in this invention allows for independent adjustment of the emission direction of a single laser rangefinder, as all beam apertures are located in the same plane, unaffected by other laser rangefinders. This avoids the problem of multiple adjustments for each laser rangefinder. This is one of the outstanding advantages of this invention.

[0046] Example 2

[0047] The difference from Embodiment 1 is that the inner surface of the inner ring of the calibration component is provided with a fine inner scribe line for flatness adjustment, and the inner scribe line passes through the center of the inner circumference of all inner ring beam through holes; the outer surface of the outer ring of the calibration component is provided with a fine outer scribe line for flatness adjustment, and the outer scribe line passes through the center of the outer circumference of all outer ring beam through holes; the scribe line is a fine scribe line, generally with a line width of no more than 0.5 mm, and in this embodiment it is set to 0.2 mm.

[0048] Preferably, the adjustment method further includes first adjusting the flatness of the emitted light beam, and then adjusting the in-plane emission direction. Generally, flatness adjustment can be achieved by adjusting the height of the head or tail of the laser rangefinder in the measuring device. Specific adjustment structures include screw fine-tuning mechanisms or adding / removing ultra-thin shims. For the inner diameter measuring device, the flatness is adjusted so that the inner graduation line is located at the center line of each laser rangefinder spot; for the outer diameter measuring device, the flatness is adjusted so that the outer graduation line is located at the center line of each laser rangefinder spot. The in-plane emission direction is adjusted by adjusting the left-right direction of the head or tail of the laser rangefinder in the measuring device. Specific adjustment structures include screw fine-tuning mechanisms or adding / removing ultra-thin shims. For the inner diameter measuring device, the left-right direction of the emitted light beam of each laser rangefinder is adjusted so that the spot radiates outward sequentially through the center of the corresponding inner ring beam aperture and the center of the outer ring beam aperture; for the outer diameter measuring device, the left-right direction of the emitted light beam of each laser rangefinder is adjusted so that the spot radiates inward sequentially through the center of the corresponding outer ring beam aperture and the center of the inner ring beam aperture.

[0049] By employing both scribed lines and beam aperture adjustment designs, the horizontal and vertical adjustments of the laser rangefinder's emitted light are separated, allowing for independent adjustment without interference. While in principle, adjusting horizontally first and then vertically, or vice versa, or even directly aiming at the final target through the beam aperture and adjusting horizontally and vertically simultaneously or alternately, is theoretically more convenient for practical engineering implementation. After positioning the measuring device and auxiliary adjustment device relative to each other, adjusting the vertical direction of the light according to the scribed lines first, and then adjusting the horizontal direction according to the beam aperture, is simpler and smoother. Generally, two adjustments are sufficient to achieve the desired result, further improving the installation and adjustment efficiency of the rotating shaft aperture measuring device. This is the second significant advantage of the invention.

[0050] Example 3

[0051] The difference from Example 2 is that, in Example 2, after adjustment using the double-ring calibration component, the actual values ​​of the included angles between the laser rangefinders are quantitatively calibrated through installation parameter calibration. These installation parameters include the relative installation angles of each laser rangefinder (e.g., relative to a reference laser rangefinder) and their installation positions (i.e., the starting position of the ranging point). If the calibration results do not meet the requirements, the fine-tuning mechanism of the corresponding laser rangefinder can be fine-tuned again based on the deviation, and then calibrated again, repeating this process until the requirements are met. The adjustment amount of the fine-tuning mechanism of each laser rangefinder can be obtained based on experience; for example, one rotation of the spiral fine-tuning mechanism corresponds to an angle change (similarly, adding or subtracting a 0.1mm thick shim on one side corresponds to an angle change). Through quantitative fine-tuning and subsequent recalibration, empirical values ​​can be obtained, thus facilitating precise and rapid fine-tuning. This is also the third prominent advantage of the method of this invention.

[0052] Example 4

[0053] The difference from Embodiment 1 is that the calibration component has four beam through holes set at 90° intervals on the inner and outer rings respectively.

[0054] Example 5

[0055] The difference from Embodiment 1 is that the calibration component has three beam through holes set at 120° intervals on the inner and outer rings respectively.

[0056] Example 6

[0057] The difference from Embodiment 1 is that the calibration element has 12 beam through holes at 30° intervals on both the inner and outer rings, as shown below. Figure 1As shown, this calibration component can simultaneously meet the installation and adjustment requirements of various symmetrically arranged shaft / aperture measuring devices, such as three laser rangefinders with adjacent included angles of 120°, four laser rangefinders with adjacent included angles of 90°, six laser rangefinders with adjacent included angles of 60°, and twelve laser rangefinders with adjacent included angles of 30°. Although the calibration component design in this embodiment takes into account a certain degree of versatility and can meet the installation and adjustment requirements of various measuring devices such as 30°, 60°, 90°, and 120°, when there are installation and adjustment requirements for measuring devices with other special included angles such as 13°, it is necessary to customize it again, thereby forming a new embodiment. There are many such variations of embodiments, and all of them should fall within the protection scope of this invention.

[0058] Example 7

[0059] The difference from Embodiment 1 is that the calibration component has 24 beam through holes set at 15° intervals on the inner and outer rings respectively, which can adapt to the precise adjustment requirements of the customized included angle between various rotating body shaft aperture measuring devices and laser rangefinders.

[0060] As in Embodiments 6 or 7, a single auxiliary adjustment device can adapt to the installation and adjustment requirements of various measuring devices, which is also the fourth prominent advantage of this invention.

[0061] Example 8

[0062] The difference from Embodiment 1 is that when the outer diameter measuring device is installed and adjusted, a spot observation ring or observation cylinder is set on the inner side of the inner ring; when the inner diameter measuring device is adjusted, a spot observation ring or observation plate is set on the outer side of the outer ring; the spot observation ring, observation cylinder or observation plate are collectively referred to as the observation device, which is not shown in the figure. This setting makes it easier to observe whether the spot passes through the beam aperture and makes it easier to adjust the position of the spot.

[0063] Preferably, the calibration component used for the installation and adjustment of the outer diameter measuring device has corresponding marks set on the outer surface of the observation ring or observation cylinder at the position corresponding to the beam through hole. The marks include dot marks, asterisk marks, + marks or x marks, etc., which are convenient for determining the center position of the light spot.

[0064] Preferably, in the calibration component used for the installation and adjustment of the outer diameter measuring device, the observation ring or observation cylinder is fixedly connected to the inner ring of the calibration component. The fixing structure should not obstruct the light from the beam aperture or the placement of the measuring device during installation and adjustment. For example, an upper or lower U-shaped bracket can be used for bridging, or a planar bracket can be used for fixing. Existing technology can achieve this goal. After the observation device is fixedly connected to the inner ring, the calibration component can generally only be used for the installation and adjustment of the outer diameter measuring device. In this case, setting a corresponding light spot position mark on its outer surface is more conducive to adjustment. If the two are not fixedly connected, a light spot position mark is generally not set, because repositioning may not be accurate. The observation device is only used to observe whether the light spot is emitted through the corresponding beam aperture.

[0065] Preferably, the inner surface of the observation ring or observation plate (collectively referred to as the observation device, not shown in the figure) of the calibration component used for the installation and adjustment of the inner diameter measuring device is marked with corresponding marks at the positions corresponding to the beam through hole. The marks include dot marks, asterisk marks, + marks or x marks, etc., which are convenient for determining the center position of the light spot.

[0066] Preferably, in the calibration component used for the installation and adjustment of the inner diameter measuring device, the observation ring or observation plate is fixedly connected to the outer ring of the calibration component. The fixed structure should not obstruct the light from the beam aperture or the placement of the measuring device during installation and adjustment. For example, an upper or lower U-shaped bracket can be used for bridging, or a flat bracket can be used for fixed connection. Existing technology can achieve this goal. After the observation device is fixedly connected to the outer ring, the calibration component can generally only be used for the installation and adjustment of the inner diameter measuring device. In this case, setting a corresponding light spot position mark on its inner surface is more conducive to adjustment. If the two are not fixedly connected, a light spot position mark is generally not set, because repositioning may not be accurate. The observation device is only used to observe whether the light spot is emitted through the corresponding beam aperture.

[0067] Example 9

[0068] like Figure 1 and Figure 2 As shown, an auxiliary adjustment device for a rotating shaft / aperture measuring device includes a coplanar double-ring structure. The double rings include an outer ring B1 and an inner ring B2. According to the original design angle requirements of the laser rangefinder in the laser diameter measuring device, corresponding beam through-holes B3 are respectively set in the inner ring and the outer ring. The diameter of the beam through-hole is not greater than the spot diameter of the laser rangefinder. The double rings are fixedly connected, and the connection structure B4 is designed to avoid blocking the light from the beam through-hole.

[0069] Example 10

[0070] The difference from Embodiment 8 is that the inner surface of the inner ring is further provided with a fine inner etched line for flatness adjustment, which passes through the center of the inner circumference of all inner ring beam through holes; the outer surface of the outer ring is provided with a fine outer etched line for flatness adjustment, which passes through the center of the outer circumference of all outer ring beam through holes; the etched lines are fine etched lines, generally with a line width of no more than 0.5 mm, and in this embodiment, it is designed to be 0.1 mm.

[0071] Example 11

[0072] The difference from Embodiment 8 is that a light spot observation ring or observation cylinder is provided on the inner side of the inner ring; and / or a light spot observation ring or observation plate is provided on the outer side of the outer ring; this arrangement makes it easier to observe whether the light spot passes through the beam aperture and makes it easier to adjust the position of the light spot.

[0073] The basic principle of this invention is to address the difficulty of calibrating and adjusting high-precision laser measuring equipment, especially for rotary shaft / aperture measuring devices integrating multiple laser rangefinders, where precisely designing the relative installation positions of each laser rangefinder is even more challenging. This invention utilizes a double-ring calibration component, i.e., an auxiliary adjustment device, with its beam through-hole and scribe line design, to transform the relative positional adjustment of multiple laser rangefinders into independent adjustment of each rangefinder. Furthermore, it separates the vertical (flatness) and horizontal (in-plane pointing) related adjustments of a single laser rangefinder, allowing for independent horizontal and vertical adjustments, and provides a specific adjustment method.

[0074] The above description is only a partial embodiment of the relatively systematic and comprehensive installation and adjustment method of the rotating shaft aperture measuring device and the auxiliary adjustment device of the present invention. In fact, regarding the design of the included angle between the two beam apertures, the further design of the light spot mark on the observation device to further improve the adjustment accuracy, the fixing method of the inner and outer rings, the addition of other support structures to the auxiliary adjustment device, the observation device, and the corresponding differences in the method brought about by the improvement of the auxiliary adjustment device, these combinations or preferred solutions should also be considered within the scope of protection of the present invention, and will not be listed one by one here.
