Abstract
Description
Technical Field
[0001] This utility model belongs to the field of inspection platform technology, specifically a multi-camera collaborative marine parts size inspection platform. Background Technology
[0002] Marine component dimensional inspection benches are high-precision automated inspection equipment designed specifically for the shipbuilding industry. By integrating machine vision, laser scanning, or coordinate measuring machine (CMM) technology, they enable rapid, non-contact measurement of the geometric dimensions, form and position tolerances, and surface defects of marine components (such as propellers, rudder shafts, and pipe joints). Their core advantage lies in their ability to efficiently handle the challenges of inspecting large-sized, irregularly shaped, and high-precision marine components, supporting batch inspection and data traceability. Applications cover ship design verification, production process quality control, assembly compatibility checks, and reverse engineering of old parts. They can significantly reduce manual measurement errors and improve inspection efficiency by more than 30%, while meeting the stringent certification standards of classification societies (such as CCS and DNV) for key components. They are a crucial tool for promoting the digital and intelligent transformation of the shipbuilding industry.
[0003] Existing marine component dimensional inspection stations typically use a single camera for inspection. However, the limited field of view of a single camera easily leaves blind spots, resulting in incomplete measurements of complex curved surfaces or irregularly shaped parts. Furthermore, the lack of multi-view data fusion makes it difficult to guarantee the measurement accuracy and reliability of geometric tolerance analysis for large-sized parts. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a multi-camera collaborative marine parts size inspection station, which effectively solves the problem that the existing marine parts size inspection station usually uses a single camera for inspection, while the single camera has a limited field of view and is prone to leaving blind spots, and the measurement of complex curved surfaces or irregularly shaped parts is incomplete.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-camera collaborative marine parts dimensional inspection table, comprising a worktable, a support frame fixedly installed on one side of the top of the worktable, support legs fixedly installed on both sides of the bottom of the worktable, a placement platform fixedly installed in the middle of the top of the worktable via a support column, a first vision camera fixedly installed in the inner bottom of the support frame, a second vision camera provided on the upper part of one side of the placement platform, and a third vision camera provided on the upper part of the other side of the worktable, a servo motor fixedly installed at the bottom of the worktable via a support base, a transmission component provided at the output end of the servo motor, the transmission component being connected to the second and third vision cameras, and when the servo motor is running, power is output to the second and third vision cameras through the transmission component, causing the second and third vision cameras to rotate and inspect marine parts.
[0006] Preferably, the transmission assembly includes a driving bevel gear, which is fixedly installed at the output end of the servo motor. A driven bevel gear is meshed with the upper part of the surface of the driving bevel gear. A positioning seat is rotatably installed at the end of the driving bevel gear away from the servo motor. The top of the positioning seat is fixedly connected to the bottom of the worktable.
[0007] Preferably, a rotating shaft is fixedly installed on the top of the driven bevel gear. The surface of the rotating shaft is rotatably connected to the worktable through a bushing. The top of the rotating shaft extends to the upper part of the worktable and is fixedly installed with a drive gear. A positioning frame is rotatably installed on the top of the drive gear. The bottom end of the positioning frame is fixedly connected to the table surface of the worktable. An external gear ring is meshed with the circumferential surface of the drive gear and is sleeved on the surface of the support column. A rotating sleeve is fixedly installed on the top of the external gear ring and is rotatably installed on the surface of the support column. The lower part of one side of the rotating sleeve is fixedly connected to the third vision camera through a support arm, and the upper part of the other side of the rotating sleeve is fixedly connected to the second vision camera through a support rod.
[0008] Preferably, connecting rods are fixedly installed on both the front and rear sides of the rotating sleeve, and slide bars are fixed at the bottom of the connecting rods. An annular groove is provided in the middle of the worktable surface, and two slide bars are slidably installed inside the annular groove.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator places the marine parts on the placement platform, and then starts the servo motor to drive the active bevel gear to rotate along the positioning seat. When the active bevel gear rotates, it drives the rotating shaft to rotate inside the bushing through the driven bevel gear. When the rotating shaft rotates, it drives the drive gear to rotate along the positioning frame. When the drive gear rotates, it drives the rotating sleeve to rotate through the external gear ring.
[0010] When the rotating sleeve rotates, the second and third vision cameras are driven to rotate and inspect the marine parts laterally and obliquely upwards via the support rod and support arm, respectively. The first vision camera also inspects from the top, achieving collaborative inspection through the three vision cameras. This allows the marine parts dimensional inspection station to comprehensively and effectively inspect the dimensions of marine parts through multi-camera collaboration, thereby ensuring the measurement accuracy and reliability of form and position tolerance analysis for large-sized parts.

When the servo motor 9 is running, it outputs power to the second vision camera 7 and the third vision camera 8 through the transmission assembly, causing the second vision camera 7 and the third vision camera 8 to rotate and inspect marine parts.
[0020] In use, the operator places the marine parts on the placement platform 5, and then starts the servo motor 9 to drive the transmission assembly. The transmission assembly drives the second vision camera 7 and the third vision camera 8 to rotate and inspect the marine parts laterally and obliquely upwards. Together with the first vision camera 6, the first vision camera inspects from the top. The three vision cameras work together to achieve coordinated inspection. This allows the marine parts dimensional inspection platform to comprehensively and effectively inspect the dimensions of marine parts through multi-camera collaboration, thereby ensuring the measurement accuracy of large-sized parts and the reliability of geometric tolerance analysis.
[0021] The transmission assembly includes a drive bevel gear 11, which is fixedly mounted on the output end of the servo motor 9. A driven bevel gear 13 is meshed with the upper part of the surface of the drive bevel gear 11. A positioning seat 12 is rotatably mounted on the end of the drive bevel gear 11 away from the servo motor 9. The top of the positioning seat 12 is fixedly connected to the bottom of the worktable 1.
[0022] A rotating shaft 14 is fixedly mounted on the top of the driven bevel gear 13. The surface of the rotating shaft 14 is rotatably connected to the worktable 1 through a bushing 15. The top of the rotating shaft 14 extends to the upper part of the worktable 1 and is fixedly mounted on a drive gear 16. A positioning frame 17 is rotatably mounted on the top of the drive gear 16. The bottom end of the positioning frame 17 is fixedly connected to the table surface of the worktable 1. An external gear ring 18 is meshed on the circumferential surface of the drive gear 16. The external gear ring 18 is sleeved on the surface of the support column 4. A rotating sleeve 19 is fixedly mounted on the top of the external gear ring 18. The rotating sleeve 19 is rotatably mounted on the surface of the support column 4. The lower part of one side of the rotating sleeve 19 is fixedly connected to the third vision camera 8 through a support arm 20. The upper part of the other side of the rotating sleeve 19 is fixedly connected to the second vision camera 7 through a support rod 21.
[0023] The operator starts the servo motor 9 to drive the active bevel gear 11 to rotate along the positioning seat 12. When the active bevel gear 11 rotates, it drives the rotating shaft 14 to rotate inside the bushing 15 through the driven bevel gear 13. When the rotating shaft 14 rotates, it drives the drive gear 16 to rotate along the positioning frame 17. When the drive gear 16 rotates, it drives the rotating sleeve 19 to rotate through the external gear ring 18.
[0024] When the rotating sleeve 19 rotates, it drives the second vision camera 7 and the third vision camera 8 to rotate and detect the marine parts laterally and obliquely upward through the support rod 21 and the support arm 20, respectively, and cooperates with the first vision camera 6 to detect from the top, so as to achieve coordinated detection through the three vision cameras.
[0025] Connecting rods 22 are fixedly installed on both the front and rear sides of the rotating sleeve 19. Slide strips 23 are fixed at the bottom of the connecting rods 22. An annular groove 24 is provided in the middle of the worktable 1, and two slide strips 23 are slidably installed inside the annular groove 24.
[0026] When the rotating sleeve 19 rotates, it drives the two slide bars 23 to slide inside the annular groove 24 through the two connecting rods 22, so as to increase the stability of the rotating sleeve 19 during rotation, thereby improving the stability of the second vision camera 7 and the third vision camera 8 during rotation detection.
