Description

Technical Field

[0001] This invention relates to the field of shipbuilding equipment technology, and in particular to an auxiliary device for manufacturing curved sections of ships. Background Technology

[0002] During shipbuilding, some sections are curved sections. Curved sections refer to sections whose outer plates are not flat but have a curved cross-section. During assembly, the welding shrinkage of these curved sections is inconsistent, leading to poor alignment at the joints (the ends where sections are assembled with other sections). Before assembling sections, these joints need to be adjusted by marking and cutting to ensure alignment and facilitate subsequent assembly. Currently, joint adjustment generally involves two steps: first, marking, which is done using a total station for measurement, followed by simulation analysis, and then manually marking intersections point by point. These intersections are then connected using a soft spline to form cutting and inspection lines. Second, cutting, which is done using a 3D cutting machine along the cutting lines. During the cutting process, the position and angle of the cutting torch need to be constantly adjusted. The existing technology has the following drawbacks: 1. The scribing and cutting operations are cumbersome, requiring a large amount of equipment and manpower, resulting in very low efficiency; 2. Manual cutting results in uneven cutting positions, requiring grinding to correct the joint, leading to low cutting accuracy and a very large amount of correction work. Summary of the Invention

[0003] The purpose of this invention is to provide an auxiliary device for manufacturing curved sections of ships. It has a simple structure and can accurately and quickly scribing and cutting the joints of curved sections of ships, thus reducing the difficulty of operation.

Each bracket includes a base, a support rod, a first connecting rod, and a universal connector. The base is detachably connected to a segmented outer plate. The support rod is mounted on the base. The first connecting rod is mounted on the support rod. The first connecting rod extends horizontally. The support rod can be extended and retracted vertically and / or the first connecting rod can be moved along the length of the support rod to adjust its height. The universal connector is mounted on the first connecting rod.

[0007] A slide rail is connected to all of the universal joints so that the slide rail is angularly adjustable relative to the first connecting rod. The universal joint has a locking structure that can lock the slide rail so that the slide rail is held in the adjusted position.

[0008] A slide block, which is slidably mounted on the slide rail, has a through mounting hole.

[0010] A fixing base is provided at one end of the second connecting rod away from the slide and on one side of the roller. The fixing base is used for detachably connecting the marking pen and the cutting torch of the cutting device.

[0011] As a preferred embodiment of the auxiliary device for manufacturing curved sections of ships, a laser mechanism is provided on the slide.

[0012] As a preferred embodiment of the auxiliary device for manufacturing curved sections of ships, the roller is rotatably connected to the second connecting rod via a roller frame, and an angle display is provided on the roller frame, the fixed base, or the second connecting rod.

[0013] As a preferred embodiment of the auxiliary device for manufacturing curved sections of ships, an electromagnet is installed inside the base, and a control switch for controlling the opening and closing of the electromagnet is provided on the base; or...

[0014] The base is a magnetic base.

[0015] As a preferred embodiment of the auxiliary device for manufacturing curved sections of ships, the distance between the support rod and the slide rail is adjustable.

[0016] As a preferred embodiment of the auxiliary device for manufacturing curved sections of ships, it further includes a first adjustment and locking mechanism. An adjustment seat is connected to the support rod. The adjustment seat has a first adjustment hole through it along the axis of the first connecting rod. The end of the first connecting rod away from the universal joint is inserted into the first adjustment hole. The first adjustment and locking mechanism connects the first connecting rod and the adjustment seat to adjust the position of the first connecting rod and the adjustment seat and lock the first connecting rod on the adjustment seat.

[0017] As a preferred embodiment of the auxiliary device for manufacturing curved sections of ships, it also includes a second adjustment and locking mechanism. The adjustment seat has a second adjustment hole in the vertical direction, and the support rod passes through the second adjustment hole. The second adjustment and locking mechanism connects the support rod and the adjustment seat to adjust the position of the support rod and the adjustment seat and lock the support rod on the adjustment seat.

[0018] As a preferred embodiment of the auxiliary device for manufacturing curved sections of a ship, the slide is provided with a first seat plate and a second seat plate spaced apart along a second direction. The first seat plate is slidably connected to the slide rail, and the second seat plate is located on the side of the first seat plate away from the slide rail. At least two sets of first pulley groups are spaced apart along a first direction within the first and second seat plates. Each set of first pulley groups includes at least one first pulley. The two sets of first pulley groups are respectively pressed against both sides of the second connecting rod along the first direction to guide the movement of the second connecting rod in the vertical direction. A limit plate is provided at the top of the second connecting rod to restrict the second connecting rod from detaching from the slide.

[0019] As a preferred embodiment of an auxiliary device for manufacturing curved sections of a ship, the first pulley block is provided with at least two first pulleys spaced apart along the vertical direction; and / or

[0020] The slide rail has a flat plate structure. A second pulley group is provided on one side of the first base plate near the slide rail.

The two second pulleys are respectively locked on the two sides of the slide rail in the vertical direction. The second pulleys rotate relative to the first base plate.

[0021] As a preferred embodiment of the auxiliary device for manufacturing curved sections of a ship, a spring is also provided between the first base plate and the second base plate. The spring is sleeved on the outer periphery of the second connecting rod, and the spring always has the tendency to drive the second connecting rod to move downward.

[0022] The beneficial effects of this invention are as follows: By setting up a bracket, the auxiliary device for segmented manufacturing of the entire ship's curved surface can be temporarily fixed at the location on the outer plate where marking and cutting are required. A slide rail is installed on the bracket, and a universal connector is used to connect the slide rail, allowing the position and angle of the slide rail to be adjusted to accommodate different curved surface angles on the outer plate. The slide block slides on the slide rail, enabling the second connecting rod on the slide block and the fixed seat to move on the curved outer plate. The second connecting rod, which can move vertically, can also coordinate with the different curved surface movements of the outer plate to complete the marking and cutting work, simplifying the difficult marking and cutting processes. This improves manufacturing precision. After the auxiliary device for manufacturing curved sections of a ship is fixed in place and the angle is adjusted, the drive slide can move on the slide rail to complete accurate marking and cutting work, reducing the intensity of operation and requiring only one person to operate the entire process. By setting rollers at the bottom of the second connecting rod, the rollers are rolled and connected to the outer plate, which makes the slide carrying the second connecting rod, the fixed seat, the marking pen and the cutting torch move more smoothly and avoids jamming. At the same time, it can also reduce the wear of the marking pen and prevent the cutting torch from directly contacting the outer plate, thus extending the service life of the marking pen and the cutting torch.

[0036] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail 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.

[0037] Reference Figure 1 As shown, the present invention provides a ship curved section manufacturing auxiliary device 100, which is used for the trimming of ship curved sections 200. Before assembling sections 200 together, the ship curved section manufacturing auxiliary device 100 assists in marking and cutting on the outer plate 210 at the joint position of sections 200, so that the joint is flush, which facilitates the accurate assembly of sections 200 together later.

[0038] In this embodiment, as Figures 1 to 4As shown, this auxiliary device 100 for manufacturing curved sections of a ship includes a bracket 1, a slide rail 2, a slide block 3, a second connecting rod 4, and a fixed base 6. There are two brackets 1, which are spaced apart along a first direction, which refers to the length direction of the slide rail 2 and is horizontal. The bracket 1 includes a base 101, a support rod 102, a first connecting rod 103, and a universal connector 104. The base 101 is detachably connected to the outer plate 210 of the section 200. In specific installation, the two bases 101 are respectively set at both ends of the scribing direction of the outer plate 210 to be scribed. The support rod 102 is set on the base 101, and the first connecting rod 103 is set on the support rod 102. The first connecting rod 103 extends horizontally and can be moved along the length direction of the support rod 102 to adjust its height. The universal connector 104 is set on the first connecting rod 103. The slide rail 2 is connected to all the universal joints 104. That is, the slide rail 2 is connected to two brackets 1 along its own length. The universal joints 104 connect the slide rail 2 and the first connecting rod 103, so that the slide rail 2 can be adjusted at an angle relative to the first connecting rod 103. The universal joints 104 have a locking structure, which can lock the slide rail 2 so that the slide rail 2 is held in the adjusted position. The slide seat 3 is slidably mounted on the slide rail 2. The slide seat 3 has a through mounting hole 301. One end of the second connecting rod 4 passes through the mounting hole 301 and is slidably connected to the slide seat 3. The lower end of the second connecting rod 4 is rotatably mounted with a roller 5. The roller 5 is in rolling contact with the surface of the outer plate 210. The fixing seat 6 is located at the end of the second connecting rod 4 away from the slide seat 3 and on one side of the roller 5. The fixing seat 6 is used to detachably connect the marking pen (not shown in the figure) and the cutting torch 300 of the cutting device.

[0039] The ship surface segment manufacturing auxiliary device 100 of this embodiment of the invention uses a bracket 1 to temporarily fix the entire device at the location on the outer plate 210 where marking and cutting are required. A slide rail 2 is mounted on the bracket 1, and a universal connector 104 connects to the slide rail 2, allowing the position and angle of the slide rail 2 to be adjusted to accommodate different curvature angles of the outer plate 210. A slide block 3 slides on the slide rail 2, enabling the second connecting rod 4 and the fixing seat 6 on the slide block 3 to move on the curved outer plate 210. The second connecting rod 4, which can move vertically, can also move with the different curvatures of the outer plate 210 to complete the marking and cutting work. By simplifying the scribing and cutting process and improving manufacturing precision, the auxiliary device 100 for manufacturing curved sections of a ship can be fixed in place and its angle adjusted. The drive slide 3 can move on the slide rail 2 to complete accurate scribing and cutting work, reducing the intensity of operation and requiring only one person to operate the entire process. By setting a roller 5 at the bottom of the second connecting rod 4, and the roller 5 rollingly connecting with the outer plate 210, the slide 3 can move more smoothly carrying the second connecting rod 4, the fixed seat 6, the scribing pen, and the cutting torch 300, avoiding jamming. At the same time, it can also reduce the wear of the scribing pen and prevent the cutting torch 300 from directly contacting the outer plate 210, thus extending the service life of the scribing pen and the cutting torch 300.

[0040] The number of brackets 1 is not limited to two; the number can be increased according to the length of the outer plate 210 along the scribing direction. The number of brackets 1 is described in detail here.

[0041] Preferably, a laser mechanism 7 is provided on the slide block 3. By providing the laser mechanism 7, the laser mechanism 7 detects the position of the slide rail 2 relative to the outer plate 210, facilitating accurate adjustment of the slide rail 2's position, i.e., adjusting the angle of the slide rail 2 to align with the allowance line point of the curved surface of the outer plate 210 of segment 200. More preferably, the laser mechanism 7 is rotatably mounted on the slide block 3. By rotating the laser mechanism 7 onto the slide block 3, one laser mechanism 7 can collect three points at different positions, adjusting the position and angle of the slide rail 2 according to the principle of three points forming a plane.

[0042] Optionally, such as Figure 1 and Figure 6 As shown, an angle display 9 can also be provided to display the angle of the marking pen or cutting torch 300 on the fixing seat 6 of the second connecting rod 4. In this embodiment, the roller 5 is rotatably connected to the second connecting rod 4 via a roller frame 8, and the angle display 9 is mounted on this roller frame 8. In other embodiments, the angle display 9 can also be directly mounted on the second connecting rod 4 or the fixing seat 6.

[0043] In one embodiment, an electromagnet (not shown in the figure) is installed inside the base 101, and a control switch 105 is installed on the base 101 to control the electromagnet's opening and closing. By installing the electromagnet, the base 101 can be magnetically fixed to a designated position on the outer plate 210 as needed. The control switch 105 facilitates the magnetic fixing and unlocking of the base 101. In other embodiments, the electromagnet is not limited to being installed inside the base 101; the base 101 can also be installed on the outer plate 210 using other detachable connection methods, such as installing a suction cup on the base 101, or temporarily spot-welding the base 101 to the outer plate 210. In other embodiments, an electromagnet with a control switch 105 may not be used; the base 101 can be directly set as a magnetic base. A magnetic base does not require power and is relatively easy to operate. Preferably, the base 101 is a switch-type magnetic base.

[0044] In addition, to match the curved outer plate 210, the bottom of the base 101 can also be set to be arc-shaped, so that the base 101 fits the outer plate 210 better.

[0045] Furthermore, such as Figure 1 and Figure 7 As shown (some of the reference numerals in the accompanying drawings are retained), Figure 2 To be continued Figure 6 The distance between the support rod 102 and the slide rail 2 is adjustable.

[0046] Specifically, an adjusting seat 10 is connected to the support rod 102. The adjusting seat 10 has a first adjusting hole extending through it along the axis of the first connecting rod 103. The end of the first connecting rod 103 away from the universal joint 104 is inserted into the first adjusting hole. The ship curved section manufacturing auxiliary device 100 also includes a first adjusting locking mechanism. The first adjusting locking mechanism connects the first connecting rod 103 and the adjusting seat 10 to adjust the position of the first connecting rod 103 and the adjusting seat 10 and lock the first connecting rod 103 onto the adjusting seat 10. By setting the first adjusting locking mechanism, the position of the adjusting seat 10 in the axial direction of the first connecting rod 103 can be adjusted when not locked. After adjustment, the first adjusting locking mechanism locks the position to prevent relative movement of the adjusting seat 10 relative to the first connecting rod 103.

[0047] Furthermore, the first adjusting locking mechanism includes a first adjusting gear (not shown in the figure), a first adjusting rack 106, and a first turning shaft 107. The first adjusting gear is rotatably disposed within the adjusting seat 10 and partially located within the first adjusting hole. The first adjusting rack 106 is fixed to the first connecting rod 103, with its length direction aligned with that of the first connecting rod 103. The first adjusting rack 106 passes through the first adjusting hole and meshes with the first adjusting gear. One end of the first turning shaft 107 is connected to the rotation center of the first adjusting gear to drive its rotation. The other end of the first turning shaft 107 extends outside the adjusting seat 10 and is connected to a first handle 108. The meshing of the gear and rack allows for precise position adjustment of the adjusting seat 10 on the first connecting rod 103, reducing adjustment difficulty. Furthermore, without external force controlling the rotation of the first turning shaft 107, the first adjusting gear and the first adjusting rack 106 can mesh tightly, preventing positional movement and thus achieving locking.

[0048] In other embodiments, the adjustment seat 10 and the first connecting rod 103 are not limited to being adjusted and locked by means of gears and racks. Adjustment and locking can also be achieved by other means. For example, the support rod 102 is connected to the adjustment seat 10, and the adjustment seat 10 has a first adjustment hole through it along the axis of the first connecting rod 103. The end of the first connecting rod 103 away from the universal connector 104 is inserted into the first adjustment hole. The adjustment seat 10 is also provided with a first locking member. The first locking member locks the first connecting rod 103 onto the adjustment seat 10. The first locking member includes a first locking rod and a first screw handle provided at one end of the first locking rod. The outer circumference of the first locking rod is provided with threads. The adjustment seat 10 has a threaded hole communicating with the first adjustment hole. The end of the first locking rod away from the first screw handle is screwed into the threaded hole. When the first locking rod extends into the first adjustment hole and abuts against the outer wall of the first connecting rod 103, the adjustment seat 10 is locked onto the first connecting rod 103.

[0049] In one embodiment, the ship curved surface segment manufacturing auxiliary device 100 further includes a second adjustment and locking mechanism. An adjustment seat 10 has a second adjustment hole (not shown in the figure) in the vertical direction. A support rod 102 passes through the second adjustment hole. The second adjustment and locking mechanism connects the support rod 102 and the adjustment seat 10 to adjust the position of the support rod 102 relative to the adjustment seat 10 and lock the support rod 102 onto the adjustment seat 10. By providing the second adjustment and locking mechanism, without locking, this mechanism can adjust the position of the adjustment seat 10 along the axis of the support rod 102, that is, adjust the height of the adjustment seat 10 in the vertical direction. Once adjusted to the correct position, the second adjustment and locking mechanism locks the adjustment seat 10, preventing relative movement between the adjustment seat 10 and the support rod 102.

[0050] Furthermore, the second adjusting locking mechanism includes a second adjusting gear (not shown in the figure), a second adjusting rack 109, and a second turning shaft 1010. The second adjusting gear is rotatably mounted within the adjusting seat 10 and partially located within the second adjusting hole. The second adjusting rack 109 is fixed to the support rod 102, with its length direction aligned with that of the support rod 102. The second adjusting rack 109 passes through the second adjusting hole and meshes with the second adjusting gear. One end of the second turning shaft 1010 is connected to the rotation center of the second adjusting gear to drive its rotation. The other end of the second turning shaft 1010 extends outside the adjusting seat 10 and is connected to a second handle 1011. The meshing of the gear and rack allows for precise position adjustment of the adjusting seat 10 on the support rod 102, reducing adjustment difficulty. Furthermore, without external force controlling the rotation of the second turning shaft 1010, the second adjusting gear and the second adjusting rack 109 can mesh tightly, preventing positional movement and thus achieving locking. Of course, an additional locking device can be set to lock the adjusting seat 10 onto the support rod 102 to prevent the second adjusting gear from being forced to rotate due to gravity, which would cause the adjusting seat 10 to drop. The additional locking device can be a locking screw, which passes through the threaded hole on the adjusting seat 10 and abuts against the outer surface of the support rod 102 to achieve locking.

[0051] In other embodiments, the adjustment seat 10 and the support rod 102 are not limited to being adjusted and locked by means of gears and racks. Adjustment and locking can also be achieved by other means. For example, the adjustment seat 10 has a second adjustment hole (not shown in the figure) in the vertical direction, the support rod 102 passes through the second adjustment hole, and the adjustment seat 10 is also provided with a second locking member. The second locking member locks the support rod 102 onto the adjustment seat 10. The second locking member includes a second locking rod and a second screw handle provided at one end of the second locking rod. The outer periphery of the second locking rod is provided with threads, and a threaded hole communicating with the second adjustment hole is provided on the adjustment seat 10. The end of the second locking rod away from the second screw handle is screwed into the threaded hole, and when the second locking rod extends into the second adjustment hole and abuts against the outer wall of the second connecting rod 4, the adjustment seat 10 is locked onto the support rod 102.

[0052] Besides adjusting the height by sliding the adjusting seat 10 onto the support rod 102, the support rod 102 can also be designed to extend and retract vertically, achieving the same height adjustment effect. The support rod 102 of the bracket 1 can adjust its length according to the curved outer plate 210 structure to keep the slide rail 2 in a horizontal position. The structure of the support rod 102 uses a common telescopic structure, which will not be described in detail here.

[0053] In one embodiment, such as Figure 1 , Figure 2 and Figure 5As shown, the slide block 3 has a first seat plate 302 and a second seat plate 303 spaced apart along the second direction. Both the first and second directions are perpendicular to the vertical direction. The first seat plate 302 is slidably connected to the slide rail 2. The second seat plate 303 is located on the side of the first seat plate 302 away from the slide rail 2. At least two sets of first pulley groups are spaced apart along the first direction in the first seat plate 302 and the second seat plate 303. Each set of first pulley groups includes at least one first pulley 304. The two sets of first pulley groups abut against the two sides of the second connecting rod 4 along the first direction to guide the movement of the second connecting rod 4 in the vertical direction. A limit plate 11 is provided on the top of the second connecting rod 4 to restrict the second connecting rod 4 from disengaging from the slide block 3. By setting the first pulley 304, the second connecting rod 4 can slide up and down to adjust its position when moving on the curved outer plate 210. When the roller 5 at the lower end of the second connecting rod 4 is located at the lowest surface of the outer plate 210, the second connecting rod 4 extends downwards beyond the slide block 3 by a larger amount. When the roller 5 at the lower end of the second connecting rod 4 is located at the highest surface of the outer plate 210, the second connecting rod 4 extends downwards beyond the slide block 3 by a smaller amount. Moreover, this adjustment process is adjusted according to the curvature height of the outer plate 210 at any time. The first pulley 304 can ensure that the vertical extension and retraction of the second connecting rod 4 is smoother and avoid jamming.

[0054] In this embodiment, at least two first pulleys 304 are arranged at intervals along the vertical direction in the first pulley group. When each first pulley group in the vertical direction has at least two first pulleys 304, it can effectively prevent the second connecting rod 4 from swinging relative to the slide block 3 and shifting its position.

[0055] Preferably, a spring can also be provided between the first base plate 302 and the second base plate 303. The spring is sleeved on the outer periphery of the second connecting rod 4, and the spring always has a tendency to drive the second connecting rod 4 to move downward. By providing the spring, the second connecting rod 4 always has a downward tendency, which can apply a certain pressure to the roller 5, ensuring that the roller 5 always maintains a rolling state that is in contact with the outer plate 210 during the movement of the slide 3. This ensures that the marking pen can maintain the same distance from the outer plate 210, and also allows the cutting torch 300 to maintain the same distance from the outer plate 210 for cutting, avoiding the occurrence of uneven cutting due to different distances.

[0056] In this embodiment, the slide rail 2 is a flat plate structure. A second pulley set is provided on one side of the first base plate 302 near the slide rail 2. The second pulley set includes two second pulleys 305 spaced apart in the vertical direction. The two second pulleys 305 are respectively engaged on the two sides of the slide rail 2 in the vertical direction, and the second pulleys 305 rotate relative to the first base plate 302. The arrangement of the second pulleys 305 ensures that the slide block 3 can slide smoothly on the slide rail 2. Preferably, at least two sets of second pulley sets are spaced apart along the first direction. This design ensures that the slide block 3 slides more smoothly.

[0057] The fixed seat 6 is a clamping seat, which is fixed by a wing bolt, so that the marking pen or cutting torch 300 inside the clamping seat can be locked onto the fixed seat 6.

[0058] like Figures 1 to 6 As shown, the finishing work of the closure joint of segment 200 includes the following steps:

[0059] Step S10: Use a total station to measure the outer plate 210 at the joint of segment 200 and mark the three allowance line points at the cutting position.

[0060] Step S20: Magnetically fix the two bases 101 of the ship surface segment manufacturing auxiliary device 100 to the outer plate 210 according to the position of the allowance point;

[0061] Step S30: According to the line shape of the outer plate 210, roughly adjust the distance between the slide rail 2 and the outer plate 210. Then, using the laser mechanism 7, adjust the angle of the side of the slide rail 2 mounting slide 3 away from the plane of three points, so that it is consistent with the residual line point of the curved outer plate 210 of the segment 200, and lock the universal connector 104.

[0062] Step S40: Install the marking pen on the fixed base 6 and adjust the position of the second connecting rod 4 so that the roller 5 can abut against the outer plate 210 when the outer plate 210 is at its lowest position.

[0063] Step S50: Drive the slide block 3 to move, so that the slide block 3 moves from one end of the slide rail 2 to the other end and draw the allowance line 400.

[0064] Step S60: Remove the marking pen, install the cutting torch 300 on the fixed base 6, start the cutting device, and then drive the slide 3 to move from one end of the slide rail 2 to the other end, and complete the cutting along the allowance line 400.

[0065] In this embodiment, the movement is not limited to manually pushing the slide block 3. An electromagnetic adsorption and electric drive structure can also be installed on the rolling mechanism of the roller 5, thereby driving the roller 5 to move while simultaneously moving the slide block 3 automatically on the slide rail 2. For example, the roller 5 can be designed as an electromagnetically attracted roller 5, with a motor mounted on its shaft. The roller 5 is electromagnetically attracted to the outer plate 210 and runs automatically under the drive of the motor. Thus, this device can achieve semi-automatic marking or cutting of ship hull sections in all directions.
