Abstract
Description
Technical Field
[0001] This utility model relates to optical inspection in the field of shipbuilding, and in particular to an auxiliary device for adjusting the vertical attitude of a micrometer collimating telescope. Background Technology
[0002] In the construction of traditional ship propulsion systems, the optical detection method for measuring the alignment deviation of key shafting equipment using micrometer collimating telescopes and special target plates has become mature and stable, with an accuracy of up to 0.01 mm.
[0003] With the gradual development of marine propulsion systems, their composition is increasingly trending towards integration and unified layout. For new integrated marine propulsion systems, multiple types of equipment need to be tested and installed on-site, leading to a gradual increase in optical measurement items for the alignment deviation of components. Based on the different characteristics of the equipment, the measurement angles and derived measurement methods for optical measurement of alignment deviation are becoming increasingly diverse. In the "vertical method" measurement system, there is an urgent need to develop a convenient, simple, and precision-controllable auxiliary device for adjusting the vertical attitude of a micrometer collimating telescope. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies and address the problem of rapid and convenient vertical attitude adjustment of micrometer collimating telescopes in the "vertical method" of optical measurement, this application provides an auxiliary device for adjusting the vertical attitude of micrometer collimating telescopes. This device uses a liquid container as a carrier for the liquid reflective layer, protected by a stainless steel base and an aluminum alloy pressure plate. A sealed transparent layer enables the optical reflection function of the liquid reflective layer in its encapsulated state. When light rays emitted along the central axis of the micrometer collimating telescope are reflected by the horizontal reflective surface, return along their origin, and pass through the observation center point of the micrometer collimating telescope, it can be confirmed that the micrometer collimating telescope is in a vertical attitude, thus solving the technical problem of vertical attitude adjustment in the vertical method.
[0005] The solution adopted by the embodiments of this application to solve the technical problem is:
[0006] A micrometer collimating telescope vertical attitude adjustment auxiliary device includes a liquid container, a stainless steel base, an aluminum alloy pressure plate, a sealed transparent layer, an O-ring, a protective cover, and a liquid reflective layer.
[0007] The upper section of the liquid container is detachably fitted with an aluminum alloy pressure plate, and the lower section is detachably fitted with a stainless steel base. A sealing transparent layer and an O-ring are clamped between the liquid container and the aluminum alloy pressure plate to seal the liquid reflective layer inside the liquid container, thereby creating a horizontal reflective surface. A protective cover for protecting the sealing transparent layer is detachably fitted on the upper section of the aluminum alloy pressure plate.
[0008] In order to further solve the technical problems to be solved in the embodiments of this application, the liquid holding box provided in the embodiments of this application is made of polyethylene material and has an overall cup-shaped structure. The upper and lower sections are respectively provided with external threads of different nominal diameters for connecting with stainless steel base and aluminum alloy pressure plate.
[0009] Furthermore, the stainless steel base has an internal thread on its inner edge, which mates with the external thread on the lower section of the liquid container. After screwing in, it connects with the aluminum alloy pressure plate, thus protecting the liquid container.
[0010] Furthermore, the inner edge of the aluminum alloy pressure plate is provided with an internal thread, which mates with the external thread on the upper section of the liquid container. After screwing, the O-ring is squeezed and deformed by the sealing and transparent layer, thereby sealing the liquid reflective layer.
[0011] Furthermore, the sealing and transparent layer is made of optical glass with a light transmittance of ≥97% and a parallelism of the upper and lower surfaces of no more than 0.02mm.
[0012] Furthermore, the O-rings are made of rubber.
[0013] Furthermore, the liquid reflective layer is mercury.
[0014] Positive effects:
[0015] This invention uses a liquid container as the holding carrier for the liquid reflective layer. A stainless steel base and an aluminum alloy pressure plate protect the liquid container. A sealed transparent layer enables the liquid reflective layer to perform optical reflection in its sealed state. The threads between the liquid container and the aluminum alloy pressure plate compress the O-ring, causing deformation and thus fixing the sealed transparent layer and sealing the liquid reflective layer within the device. A horizontal reflective surface is constructed through the liquid reflective layer. When light rays emitted along the central axis of the micrometer collimating telescope are reflected by this horizontal reflective surface, return along their origin, and pass through the observation center point of the micrometer collimating telescope, it confirms that the micrometer collimating telescope is in a vertical orientation. This provides the prerequisite for optical measurement of component alignment deviations using the "vertical line method" at ship assembly sites, eliminating the limitations of horizontal placement of the micrometer collimating telescope, ensuring the stability and accuracy of optical measurements of component alignment deviations, improving the trial assembly and installation accuracy of equipment at ship assembly sites, and increasing the construction efficiency of ship propulsion systems.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] According to the instruction manual Figures 1-2 As shown, a micrometer collimating telescope vertical attitude adjustment auxiliary device includes a liquid container 1, a stainless steel base 2, an aluminum alloy pressure plate 3, a sealing transparent layer 4, an O-ring 5, a protective cover 6, and a liquid reflective layer 7.
[0023] The upper section of the liquid container 1 is detachably equipped with an aluminum alloy pressure plate 3, and the lower section is detachably equipped with a stainless steel base 2. A sealing transparent layer 4 and an O-ring 5 are clamped between the liquid container 1 and the aluminum alloy pressure plate 3 to seal the liquid reflective layer 7 inside the liquid container 1. A protective cover 6 for protecting the sealing transparent layer 4 is detachably installed on the upper section of the aluminum alloy pressure plate 3.
[0024] In this process, a horizontal reflective surface is constructed by liquid reflective layer 7. When light rays emitted along the central axis of the micrometer collimating telescope are reflected by the horizontal reflective surface, return along the original path, and pass through the observation center point of the micrometer collimating telescope, it can be confirmed that the micrometer collimating telescope is in a vertical orientation.
[0025] Preferably, the liquid container 1 has an overall cup-shaped structure and is made of polyethylene material to reduce the adverse effects of light reflected from the inner wall of the liquid container 1 on the observation results during the use of this device; the upper and lower sections are provided with external threads, and the nominal diameters of the external threads at both ends are different, for connection with the stainless steel base 2 and the aluminum alloy pressure plate 3.
[0026] Preferably, the stainless steel base 2 has an internal thread on its inner edge, and is detachably fitted onto the lower section of the liquid container 1 using the threaded structure. The aluminum alloy pressure plate 3 has an internal thread on its inner edge, and is detachably fitted onto the upper section of the liquid container 1 using the threaded structure. After the stainless steel base 2 and the aluminum alloy pressure plate 3 are screwed into place, their end faces are connected, thus achieving the external protection of the liquid container 1.
[0027] In this embodiment, the inner edge of the aluminum alloy pressure plate 3 is provided with an internal thread, which mates with the external thread of the upper section of the liquid container 1. After screwing, the O-ring seal 5 is squeezed by the sealing transparent layer 4 and deformed, thereby sealing the liquid reflective layer 7.
[0028] Preferably, a disc-shaped space is designed between the liquid container 1 and the aluminum alloy pressure plate 3. The upper and lower end faces of the disc-shaped space are provided with annular groove structures. Two O-rings 5 are installed in the annular groove structures respectively. The sealing and transparent layer 4 is clamped and installed in the disc-shaped space by the O-rings 5. When the liquid container 1 and the aluminum alloy pressure plate 3 are tightened, the sealing and transparent layer 4 compresses the two O-rings 5 to deform and form a sealed space.
[0029] In this embodiment, the O-ring 5 is made of rubber and is arranged in an inner and outer double layer configuration to achieve the sealing of the liquid reflective layer 7 while ensuring that the sealing transparent layer 4 is intact and does not deform.
[0030] Preferably, the sealing transparent layer 4 is optical glass, with a light transmittance of ≥97% and a parallelism of the upper and lower surfaces of no more than 0.02mm. The sealing transparent layer 4 serves as part of the sealing boundary of this device and does not cause optical path deviation to the light passing through the sealing transparent layer 4.
[0031] Preferably, the inner edge of the protective cover 6 is provided with internal threads, and the threaded structure is used to detachably fit onto the upper part of the aluminum alloy pressure plate 3, protecting the sealing and transparent layer 4 when not in use and preventing bumps and scratches.
[0032] Preferably, the liquid reflective layer 7 is placed inside the liquid container 1, providing a horizontal reflective layer in any orientation, which helps to facilitate convenient and quick adjustment of the vertical attitude of the micrometer collimating telescope.
[0033] In this embodiment, the liquid reflective layer 7 is mercury.
[0034] The working process of this embodiment:
[0035] Steps for installing structural components in confined spaces using this device:
[0036] Step 1: Complete the assembly of this device. Except for the protective cover 6, tighten and fix the liquid container 1 to the stainless steel base 2. Install the liquid reflective layer 7 into the liquid container 1. Place the O-ring 5 in the annular groove of the liquid container 1 and the aluminum alloy pressure plate 3 and install the sealing transparent layer 4. Tighten and fix the liquid container 1 to the aluminum alloy pressure plate 3.
[0037] Step 2: Adjust the micrometer collimating telescope to a basic vertical position, and place the assembled device directly below the micrometer collimating telescope, except for the protective cover 6;
[0038] Step 3: Install the light source for the micrometer collimating telescope, ensuring the light beam is emitted downwards along the central axis of the micrometer collimating telescope. See [link / reference]. Figure 2 As indicated by the downward-pointing arrow, the emitted light passes through the sealed transparent layer 4, is reflected by the liquid reflective layer 7, and then passes through the sealed transparent layer 4 again before exiting upwards. (See also...) Figure 2 The middle arrow points upwards;
[0039] Step 4: After the observer is behind the micrometer collimating telescope, observe whether the reflected light is located at the observation center point marked in the sight glass; if so, the micrometer collimating telescope has been adjusted to a vertical attitude; if not, adjust the attitude of the micrometer collimating telescope according to the direction and distance of the reflected light deflection until the reflected light is located at the observation center point, at which point the micrometer collimating telescope has been adjusted to a vertical attitude.
[0040] Step 5: Remove the device, except for the protective cover 6. Screw the protective cover 6 onto the upper part of the aluminum alloy pressure plate 3 to protect the sealing and transparent layer 4 and begin subsequent measurements.
[0041] Features of this embodiment:
[0042] The liquid container 1 is externally protected by a stainless steel base 2 and an aluminum alloy pressure plate 3, and the key component, the sealing and transparent layer 4, is externally protected by a protective cover 6. The sealing and transparent layer 4 is sealed and stored in a sealed manner using the liquid container 1, O-ring seal 5, and sealing and transparent layer 4. The sealing and transparent layer 4 enables the optical reflection function of the liquid reflective layer 7 in the sealed state, and a horizontal reflective surface is constructed through the liquid reflective layer 7. According to the principle of light reflection, when the light rays emitted along the central axis of the micrometer collimating telescope are reflected by the horizontal reflective surface and return along the original path, it can be confirmed that the micrometer collimating telescope is in a vertical position. This device has a simple structure, has no special requirements for the operating environment, and can meet the needs of rapid adjustment and confirmation of the vertical position of the micrometer collimating telescope at the ship assembly site, improving the stability and accuracy of optical measurement of the alignment deviation value of components.
