Abstract
Description
Technical Field
[0001] This utility model relates to the field of shipbuilding technology, and in particular to a tooling for detecting the flatness of the mainboard between ship ribs. Background Technology
[0002] For certain ship types with high precision requirements (such as container ships and car carriers), there are high flatness requirements for panels in certain special locations. It is necessary to check the flatness of the panels between adjacent ribs. The traditional method is mainly to have two workers pull a line and place it close to the panel position where the ribs are installed on the back. Then, a third worker uses a ruler to measure the concavity in the middle of the panel. This operation requires three people to work together, and the accuracy of the ruler reading can only be guaranteed to be ±2mm. Utility Model Content

[0023] Example: A fixture for inspecting the flatness of a mainboard between ship ribs, comprising:
[0024] Magnetic level 1;
[0025] A digital depth gauge 4, which is mounted near the center of a magnetic level 1, is used to measure the depth of the concavity of the intercostal main plate plane. It includes a slidable display 5 and a probe 6 that moves with the display 5.
[0026] The miniature slide rail 3 is fixed in the groove 2 of the magnetic level 1 and is centrally located. The digital depth gauge 4 is slidably connected to the miniature slide rail 3. The miniature slide rail 3 is parallel to the magnetic level 1 and the digital depth gauge 4 is perpendicular to the miniature slide rail 3.
[0027] I. Tooling Preparation
[0028] First, prepare the fixture for checking the flatness of the mainplate between the ship's ribs, ensuring all components are intact. This fixture mainly consists of a magnetic level 1, a slide rail 2, a miniature slide rail 3, a digital depth gauge 4, a display 5, a probe 6, a magnetic surface 7, and a magnetic block 8. Check that the length of the magnetic level 1 is 1200mm, the length of the miniature slide rail 3 is 200mm, the sliding range of the digital depth gauge 4 meets the ±90mm requirement, and that the fixture's measuring range meets the conditions of a rib spacing within 1.2m and a measuring depth within 40mm. Simultaneously, confirm that the magnetic block 8 on the magnetic surface 7 is securely fixed, and that the display 5 and probe 6 of the digital depth gauge 4 are functioning normally.
[0029] II. Tooling Installation and Debugging
[0030] The miniature slide rail 3 is fixedly installed in the groove 2 of the magnetic level 1, ensuring that the miniature slide rail 3 is centered and parallel to the magnetic level 1. Then, the digital depth gauge 4 is slidably connected to the miniature slide rail 3, ensuring that the digital depth gauge 4 can slide freely on the miniature slide rail 3 and is perpendicular to the miniature slide rail 3. Next, the magnetic level 1 is placed on the main plate between the ribs of the ship to be inspected, and the magnetic block 8 on the magnetic surface 7 is used to firmly attract the magnetic level 1 to the main plate, so that the top probe 6 of the digital depth gauge 4 is flush with the magnetic surface 7 of the magnetic level 1, and the magnetic surface 7 of the magnetic level 1 is set as the reference 0 position.
[0031] III. Flatness Inspection Process
[0032] Preliminary positioning: Place the installed testing fixture in a suitable position on the main plate between the ship's ribs, ensuring that the magnetic level 1 is in a horizontal state. This can be determined by observing the level indication on the magnetic level 1.
[0033] Data Acquisition: The digital depth gauge 4 is slid along the miniature slide rail 3, causing the probe 6 to move along the motherboard surface. During this movement, the display 5 shows the real-time depth change of the probe 6 relative to the reference 0 position, i.e., the magnetic surface 7. When the probe 6 encounters a recessed area on the motherboard plane, the display 5 shows the corresponding recess depth value.
[0034] Multi-point measurement: To comprehensively and accurately detect the flatness of the motherboard, the above data acquisition process was repeated at different locations on the motherboard between the ribs to obtain concave depth data at multiple measurement points. Since the digital depth gauge 4 can slide within a range of ±90mm, it can cover a certain detection area, thus more comprehensively reflecting the flatness of the motherboard.
[0035] IV. Data Processing and Result Judgment
[0036] Data recording: The concave depth data obtained at each measurement point will be recorded in detail for subsequent analysis.
[0037] Flatness assessment: Analyze the flatness of the motherboard based on the recorded data. If the measured recess depth values are all within the tooling depth range of 40mm, and the depth variation between each measurement point is relatively uniform, it indicates that the flatness of the motherboard meets the requirements; conversely, if there are recess depths exceeding 40mm or abnormal depth variations, it indicates that there may be a problem with the flatness of the motherboard, requiring further inspection and handling.
[0038] In summary, the tooling for detecting the flatness of the mainboard between ship ribs provided by this utility model is simple to operate, saves manpower, and reduces the original three-person operation to one person, thus reducing labor costs. Single-person use of the tooling for measurement can be carried out even in confined spaces, reducing measurement difficulty, improving measurement efficiency, and increasing measurement accuracy. The digital depth gauge has a measurement accuracy of 0.1mm, while the manual reading is about 2mm, improving detection accuracy. It is highly practical and worthy of promotion.
[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
