Abstract

This invention belongs to the field of laser measurement technology and discloses a laser measurement device for manufacturing ship parts. It includes a support frame and further comprises: a measurement component mounted on the support frame; and a detection component disposed inside the support frame via a connecting component. In this invention, the detection component contacts the surface of the ship part. During movement, when a depression or convexity appears on the surface of the ship part, a second right-angled prism moves downwards under the action of the connecting component. At this time, the laser emitted by the laser emitter changes its path as it passes through the second and first right-angled prisms, causing the laser receiver to be unable to receive the laser signal. In this process, the second right-angled prism contacts the surface of the ship part and alters the laser signal, preventing the laser signal from directly contacting transparent or highly reflective ship parts, thus avoiding affecting the accuracy of the measurement data and reducing the measurement cost of ship parts.

Description

Technical Field

[0001] This invention belongs to the field of laser measurement technology, specifically a laser measurement device for manufacturing ship parts. Background Technology

[0002] Ship parts refer to various equipment, components, and auxiliary devices used in the construction, repair, modification, or daily operation of ships. They encompass modules such as power systems, navigation equipment, hull structure, and safety and environmental protection, and are core components ensuring the functionality, safety, and compliance of ships. Laser measurement technology utilizes the high directionality, monochromaticity, and coherence of lasers. By emitting a laser beam and analyzing its reflected or scattered signals, it achieves high-precision detection of distance, displacement, velocity, shape, or surface features.

[0003] In shipbuilding, the processing of shafting, hull plates, and tubular fittings requires precise inspection of their surface flatness and circumference, and laser measurement is currently a commonly used method. However, when measuring transparent or highly reflective fittings, the laser signal reception may be abnormal due to material refraction, which in turn affects the accuracy of the measurement data. In addition, laser measurement relies on high-performance computing power to process data, which also increases the overall cost of ship fitting measurement. Therefore, a laser measurement device for ship fitting manufacturing is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a laser measuring device for manufacturing ship parts, which solves the problem that when existing lasers measure transparent or highly reflective parts, the laser signal reception is abnormal due to material refraction, thus affecting the accuracy of the measurement data.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser measuring device for manufacturing ship parts, comprising a support frame, and further comprising:

[0006] A measuring component, the measuring component being mounted on the support frame;

[0007] A detection component, which is disposed inside the support frame via a connecting component;

[0008] The measuring component includes a laser emitter fixed to the top of the support frame, a laser receiver fixed to one end of the support frame via a first connecting frame, and a first right-angled triangular prism fixed to the inside of the support frame via a second connecting frame.

[0009] The detection component includes a second right-angled triangular prism disposed inside the support frame;

[0010] When the bottom of the detection component initially contacts the surface of the ship fitting, the laser emitter is vertical to the top surface of the second right-angled prism, the vertical surface of the first right-angled prism is parallel to the vertical surface of the second right-angled prism, the laser receiver is vertical to the top surface of the first right-angled prism, and the laser signal emitted by the laser emitter is received by the laser receiver after passing through the second right-angled prism and the first right-angled prism.

[0011] Preferably, the bottom of the second right-angle prism is fixedly equipped with a first connector, and a first ball bearing is provided in the middle of the first connector.

[0012] Preferably, the connecting assembly includes a C-shaped frame fixed to the top of the second right-angled triangular prism, a guide rod fixed to the C-shaped frame, a guide frame fixed to the top of the inner wall of the support frame, and a stabilizing rod fixed to the guide frame;

[0013] The C-shaped frame slides on the stabilizing rod, and the lower end of the guide frame slides on the guide rod;

[0014] The bottom of the guide frame is provided with a second elastic element that pushes the C-shaped frame upward.

[0015] Preferably, the support frame has a guide groove on its outside, and the second right-angled triangular prism is fixedly mounted with a slide, which slides vertically along the guide groove.

[0016] Preferably, the guide assembly includes a second connector fixed to the bottom of the support frame, the bottom of the second connector is fixed with a fixing frame, and the bottom of the fixing frame is provided with a second ball bearing, which can be configured as two sets.

[0017] Preferably, the first ball contacts the surface of the ship fitting and presses down the second right-angled prism to be horizontal with the first right-angled prism, while both the first ball and the second ball are in contact with the surface of the ship fitting.

[0018] Preferably, the marking assembly includes an electromagnet fixed to the bottom of the support frame, a connecting rod is provided on the support frame, a magnet is fixed to the bottom of the connecting rod, and a first elastic element that pushes the magnet upward is sleeved on the outside of the connecting rod;

[0019] A marker pen is fixed to the bottom of the connecting rod.

[0020] Preferably, the bottom of the support frame is provided with a marking element that has the same structure as the marking component;

[0021] One end of the marker pen points to the first ball bearing, and the marker pen and the marker are red and blue, respectively.

[0022] Preferably, the top of the support frame is provided with two scales, which are symmetrically arranged with the laser receiver as the midpoint.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] This invention detects contact between the detection component and the surface of the ship's fittings. This allows the laser emitted by the laser emitter to be properly received by the laser receiver after passing through a second right-angled prism and a first right-angled prism. By pushing the support frame, the second right-angled prism moves along the surface of the ship's fittings. During this movement, if the surface of the ship's fittings becomes concave or convex, the second right-angled prism moves downwards under the action of the connecting component. At this time, when the laser emitted by the laser emitter passes through the second right-angled prism and the first right-angled prism, the laser path will be changed, causing the laser receiver to be unable to receive the laser signal. In this process, the second right-angled prism contacts the surface of the ship's fittings and changes the laser signal, avoiding direct contact between the laser signal and the transparent or highly reflective parts of the ship, thus affecting the accuracy of the measurement data and reducing the measurement cost of ship fittings.

[0025] This invention involves a detection component and a guide component moving along the surface of a ship fitting. A laser emitter emits a laser beam, which passes through a second right-angled prism and a first right-angled prism, and is received by a laser receiver. If a protrusion or depression appears on the surface of the ship fitting, the second right-angled prism moves up and down, changing the path of the laser beam. The laser receiver then cannot receive the laser signal, and the laser signal is deflected onto a scale. A sensor is installed on the scale, which, upon receiving the laser signal, is energized in conjunction with an electromagnet. Under the action of the magnetic pole, the connecting rod and the marking pen move down, compressing the first elastic element. The marking pen marks the ship fitting in red to indicate a depression and in blue to indicate a protrusion, thus facilitating subsequent inspection of the fitting and improving the accuracy of measurement and the efficiency of subsequent processing.

[0026] This invention uses offset laser signals to accurately read the undulations and drops of ship parts on a scale, ensuring measurement accuracy. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1 to 9 As shown, the present invention provides a laser measuring device for manufacturing ship parts, including a support frame 1, and further comprising:

[0039] Measurement component 2 is mounted on support frame 1;

[0040] Detection component 3 is installed inside support frame 1 via connecting component 6;

[0041] The measuring component 2 includes a laser emitter 21 fixed to the top of the support frame 1, a laser receiver 23 fixed to one end of the support frame 1 via a first connecting frame 22, and a first right-angled triangular prism 26 fixed to the inside of the support frame 1 via a second connecting frame 25.

[0042] The detection component 3 includes a second right-angled triangular prism 31 disposed inside the support frame 1;

[0043] When the bottom of the initial detection component 3 contacts the surface of the ship fittings, the laser emitter 21 and the top surface of the second right-angle prism 31 remain vertical, the vertical surface of the first right-angle prism 26 and the vertical surface of the second right-angle prism 31 remain parallel, the laser receiver 23 and the top surface of the first right-angle prism 26 remain vertical, and the laser signal emitted by the laser emitter 21 is received by the laser receiver 23 after passing through the second right-angle prism 31 and the first right-angle prism 26.

[0044] By detecting the contact between the detection component 3 and the surface of the ship parts, the laser emitted by the laser emitter 21 is able to be normally received by the laser receiver 23 after passing through the second right-angle prism 31 and the first right-angle prism 26. By pushing the support frame 1, the second right-angle prism 31 moves along the surface of the ship parts. During the movement, when the surface of the ship parts is concave, the second right-angle prism 31 moves downward under the action of the connecting component 6. At this time, when the laser emitted by the laser emitter 21 passes through the second right-angle prism 31 and the first right-angle prism 26, the laser path will be changed, causing the laser receiver 23 to be unable to receive the laser signal. At the same time, when the surface of the ship parts is convex, the second right-angle prism 31 moves upward synchronously. When the laser emitted by the laser emitter 21 passes through the second right-angle prism 31 and the first right-angle prism 26, the laser receiver 23 will be unable to receive the laser signal. The support frame 1 is equipped with a buzzer that is linked to the laser receiver 23. When the laser receiver 23 cannot receive the signal, the buzzer will work, which can determine whether the surface of the ship parts is flat.

[0045] During this process, the second right-angle prism 31 contacts the surface of the ship parts and changes the laser signal, avoiding direct contact between the laser signal and the transparent or highly reflective parts of the ship, which would affect the accuracy of the measurement data and reduce the measurement cost of the ship parts.

[0046] By further moving the support frame 1 in a circular motion along the surface of the tubular fitting, the circumferential flatness of the tubular fitting can be measured.

[0047] like Figures 3-7 As shown, a first connector 32 is fixedly mounted at the bottom of the second right-angle prism 31, and a first ball bearing 33 is provided in the middle of the first connector 32.

[0048] The first ball 33 is brought into contact with the surface of the ship fitting by the support frame 1, and the support frame 1 is pushed to make the first ball 33 move along the surface of the ship fitting, thereby improving the flexibility of the measuring device's movement.

[0049] like Figures 3-4As shown, the connecting component 6 includes a C-shaped frame 61 fixed to the top of the second right-angled triangular prism 31, a guide rod 65 fixed to the C-shaped frame 61, a guide frame 62 fixed to the top of the inner wall of the support frame 1, and a stabilizing rod 63 fixed to the guide frame 62.

[0050] C-shaped frame 61 slides on stabilizer bar 63, and the lower end of guide frame 62 slides on guide bar 65;

[0051] The bottom of the guide frame 62 is provided with a second elastic element 64 that pushes the C-shaped frame 61 upward;

[0052] The support frame 1 has a guide groove 34 on its outside, and the second right-angled triangular prism 31 has a slide 35 fixedly mounted on its outside. The slide 35 slides vertically along the guide groove 34.

[0053] The first ball bearing 33 contacts the surface of the ship fitting and presses down the second right-angled triangular prism 31. The C-shaped frame 61 moves upward along the stabilizing rod 63 to stretch the second elastic element 64. The second right-angled triangular prism 31 moves upward and remains horizontal with the middle of the first right-angled triangular prism 26. At the same time, during the upward movement of the second right-angled triangular prism 31, the slide 35 slides along the guide groove 34 to ensure the stability of the movement of the second right-angled triangular prism 31.

[0054] As the first ball bearing 33 moves along the surface of the ship fitting, when a depression appears on the surface of the ship fitting, the second elastic element 64 pulls the C-shaped frame 61 and the second right-angled triangular prism 31 downward, so that the first ball bearing 33 is located at the depression of the ship fitting, while a convexity appears on the surface of the ship fitting, pushing the second right-angled triangular prism 31 and the C-shaped frame 61 upward to compress the second elastic element 64, thus realizing the measurement of the flatness of the surface of the ship fitting.

[0055] like Figures 6-8 As shown, the guide assembly 4 includes a second connector 41 fixedly mounted to the bottom of the support frame 1. A fixing frame 42 is fixedly mounted to the bottom of the second connector 41. A second ball bearing 43 is provided at the bottom of the fixing frame 42. The second ball bearing 43 can be configured into two sets.

[0056] The first ball bearing 33 contacts the surface of the ship fitting and presses down the second right-angled prism 31 to be horizontal with the first right-angled prism 26. At the same time, both the first ball bearing 33 and the second ball bearing 43 are in contact with the surface of the ship fitting.

[0057] The support frame 1 is placed on the surface of the ship fitting. Pressing down the support frame 1 causes the second right-angled triangular prism 31 to move upward inside the support frame 1. During the upward movement, the second ball bearing 43 comes into contact with the surface of the ship fitting. At this time, both the first ball bearing 33 and the second ball bearing 43 are in contact with the surface of the ship fitting. At this time, the middle part of the vertical surface of the second right-angled triangular prism 31 is horizontal with the middle part of the vertical surface of the first right-angled triangular prism 26. The support frame 1 can then be pushed to make the second ball bearing 43 and the first ball bearing 33 move along the surface of the ship fitting, and the surface flatness can be measured.

[0058] Meanwhile, the second ball bearing 43 can be configured as two sets, such as... Figure 8 As shown, the stability of the support frame 1 is improved by two sets of second ball bearings 43, thus avoiding tilting.

[0059] like Figures 8-9 As shown, the marking component 5 includes an electromagnet 51 fixed to the bottom of the support frame 1, a connecting rod 56 is provided on the support frame 1, a magnet block 52 is fixed to the bottom of the connecting rod 56, and a first elastic member 53 is sleeved on the outside of the connecting rod 56 to push the magnet block 52 upward.

[0060] A marker pen 54 is fixedly mounted at the bottom of the connecting rod 56;

[0061] The bottom of the support frame 1 is provided with a marker 55 that has the same structure as the marker assembly 5;

[0062] One end of the marker 54 points to the first ball 33, and the colors of the marker 54 and the marker 55 are red and blue, respectively.

[0063] The top of the support frame 1 is provided with two scales 24, which are symmetrically arranged with the laser receiver 23 as the midpoint.

[0064] The detection component 3 and the guide component 4 move along the surface of the ship parts. During this process, the laser emitter 21 emits a laser, which passes through the second right-angle prism 31 and the first right-angle prism 26 and is received by the laser receiver 23. If there is a protrusion or depression on the surface of the ship parts, the second right-angle prism 31 moves up and down, changing the path of the laser. The laser receiver 23 will not be able to receive the laser signal. When there is a depression on the surface of the ship parts, the second right-angle prism 31 will move down, causing the laser signal to be deflected to the scale 24 near the end of the second right-angle prism 31. A sensor is set on the scale 24. When the laser signal is received, it is energized in conjunction with the electromagnet 51. Under the action of the magnetic pole, the connecting rod 56 and the marker pen 54 are pushed down to compress the first elastic element 53. Thus, the marker pen 54 marks the ship parts in red to indicate that the area is in a depressed state.

[0065] Conversely, when a protrusion appears on the surface of a ship fitting, the laser emitted by the laser emitter 21 is deflected onto the scale 24 at the other end by the upward movement of the second right-angle prism 31. At this time, the ship fitting is marked in blue by the marker 55 to indicate that there is a protrusion, which facilitates the subsequent inspection of the fitting and improves the accuracy of measurement and the efficiency of subsequent processing.

[0066] Meanwhile, the offset laser signal can be accurately read at scale 24 to determine the undulations and drops of the ship's components, ensuring the accuracy of the measurement.

[0067] Working principle and usage process of this invention:

[0068] By placing the support frame 1 on the surface of the ship fittings and pressing down on the support frame 1, the second right-angled triangular prism 31 moves upward inside the support frame 1. During the upward movement, the second ball 43 contacts the surface of the ship fittings. At this time, both the first ball 33 and the second ball 43 are in contact with the surface of the ship fittings. At this time, the middle part of the vertical surface of the second right-angled triangular prism 31 and the middle part of the vertical surface of the first right-angled triangular prism 26 are horizontal. The support frame 1 can then be pushed to make the second ball 43 and the first ball 33 move along the surface of the ship fittings.

[0069] When a depression appears on the surface of the ship parts during movement, the second right-angled prism 31 moves downward under the action of the connecting component 6. At this time, when the laser emitted by the laser emitter 21 passes through the second right-angled prism 31 and the first right-angled prism 26, the laser path will be changed, causing the laser receiver 23 to be unable to receive the laser signal. At the same time, when a convexity appears on the surface of the ship parts, the second right-angled prism 31 moves upward synchronously. When the laser emitted by the laser emitter 21 passes through the second right-angled prism 31 and the first right-angled prism 26, the laser receiver 23 will be unable to receive the laser signal. A buzzer linked to the laser receiver 23 is installed on the support frame 1. When the laser receiver 23 cannot receive the signal, the buzzer will work, which can determine whether the surface of the ship parts is flat.

[0070] If a protrusion or depression appears on the surface of the ship fittings, the second right-angled triangular prism 31 will move up and down, changing the path of the laser. The laser receiver 23 will then be unable to receive the laser signal. When a depression appears on the surface of the ship fittings, the second right-angled triangular prism 31 will move down, causing the laser signal to be deflected towards the scale 24 near the end of the second right-angled triangular prism 31. A sensor is installed on the scale 24. When the laser signal is received, it is energized in conjunction with the electromagnet 51. Under the action of the magnetic pole, the connecting rod 56 and the marking pen 54 are pushed down to compress the first elastic element 53. Thus, the marking pen 54 marks the ship fittings in red to indicate that the area is in a depressed state.

[0071] Conversely, when a protrusion appears on the surface of a ship fitting, the laser emitted by the laser emitter 21 is deflected to the scale 24 on the other end by the second right-angle prism 31. At this time, the ship fitting is marked in blue by the marker 55 to indicate that there is a protrusion, which facilitates the subsequent inspection of the fitting, improves the accuracy of measurement and the efficiency of subsequent processing.

[0072] Meanwhile, the offset laser signal can be accurately read at scale 24 to determine the undulations and drops of the ship's components, ensuring the accuracy of the measurement.
