Description

Technical Field

[0001] This utility application relates to the field of ship deck welding technology, and in particular to a positioning device for ship deck welding. Background Technology

[0002] Deck welding and positioning is a critical process in shipbuilding, directly affecting structural strength and watertightness. Current positioning technologies mainly rely on manual measurement and marking, temporary clamping, and rigid fixing fixtures. Manual measurement depends on tools such as measuring tapes and levels, which is inefficient, susceptible to human error, and unable to meet the high precision requirements of large decks. Temporary clamping results in poor weld quality and can easily damage the deck itself. Rigid fixing fixtures use mechanical clamps or temporary welding supports to fix the plates, but lack flexibility and may fail due to thermal deformation. Furthermore, current positioning mechanisms are insufficient for flipping the deck, requiring manual flipping and welding, which affects weld stability and quality.

[0003] Therefore, there is an urgent need for a positioning device for ship deck welding that can adapt to the welding of decks of different sizes and simultaneously perform double-sided welding of the deck. Utility Model Content

[0004] The purpose of this application is to achieve a positioning device for welding decks of different sizes and to perform double-sided welding of the decks. Compared with the prior art, it provides a positioning device for welding ship decks, including a base plate. A pair of support seats and a motor are fixedly connected to the upper end of the base plate. A rotating shaft is rotatably connected inside each pair of support seats, and both ends of the rotating shaft extend to the outside of the support seats. A transmission component is fixedly connected to one end of each of the two rotating shafts. Two fixed components are slidably connected between the pair of transmission components. A gear one is fixedly connected to the end of one of the rotating shafts away from the transmission component, and a gear two is fixedly connected to the output end of the motor. A toothed chain is meshed between the gear one and the gear two. The deck is limited by the pair of fixed components. The motor drives the gear to rotate, thereby driving the rotation of the transmission components, causing the deck to flip over, thus enabling double-sided welding of the deck.

[0005] Furthermore, the transmission assembly includes a transmission fixed seat, a bidirectional lead screw, and a pair of turntables. The transmission fixed seat has a pair of rectangular through slots, and each of its left and right end faces has a circular through hole. The bidirectional lead screw is rotatably connected in the circular through hole, and both ends of the lead screw extend to the outside of the transmission fixed seat. The pair of turntables are respectively fixedly connected to both ends of the bidirectional lead screw.

[0006] Furthermore, the fixing assembly includes a threaded screw, a lower pressure plate, two locking bolts, multiple guide rods, and a fixing seat. The upper surface of the lower pressure plate has two circular through holes II, and the upper surface of the fixing seat has two threaded through holes I and multiple circular through holes III. The two locking bolts respectively movably pass through a pair of circular through holes II and are threadedly connected to the inside of the threaded through holes I. One end of the multiple guide rods is fixedly connected to the lower surface of the lower pressure plate and is slidably connected to the inside of the multiple circular through holes III, effectively guiding the lower pressure plate to move along a predetermined trajectory.

[0007] Furthermore, a threaded through hole two is opened laterally on one side of the fixed seat. The threaded rod is threadedly connected in the threaded through hole two, and its two ends extend to the outside of the threaded through hole two. A knob is fixedly connected to one end of the threaded rod, and a baffle is fixedly connected to the other end. The baffle is located inside the fixed seat. By restricting the degree of freedom of the deck in the three directions of XYZ axis, the stability during welding is effectively improved, while adapting to the positioning of decks of different sizes.

[0008] Furthermore, the two ends of the bidirectional lead screw pass through a pair of fixed seats and are threaded into them. When the bidirectional lead screw rotates in the forward direction, it causes the two decks to move closer to each other, and when it rotates in the reverse direction, it causes the decks to move apart. The center of the lead screw has a reserved unthreaded structure to reduce the probability of the two fixed components colliding with each other.

[0009] Furthermore, two support plates are fixedly connected between a pair of transmission fixed seats. The support plates and the fixed seats in the fixed assembly jointly support the two decks and share the pressure borne by the fixed assembly when fixing the decks. The upper surfaces of the two support plates and the inner bottom surfaces of the fixed seats are at the same level, which reduces the phenomenon of welding errors caused by the different heights of the decks when they are driven to come close together by the bidirectional screw.

[0010] Furthermore, multiple fixed plates are fixedly connected to the upper surface of the base plate, and the fixed end of the electric telescopic rod is fixedly connected to the upper surface of the fixed plate. The output end of the electric telescopic rod is fixedly connected to a support block. When the electric telescopic rod reaches its maximum length, the upper surfaces of the multiple support blocks respectively fit against the lower surfaces of a pair of transmission fixed seats, which plays an auxiliary support role for the overall device. When the deck is flipped, the electric telescopic rod is scaled to its minimum position to avoid collision with the transmission components during the rotation process.

[0011] Compared to existing technologies, the advantages of this application are:

[0012] (1) The setting of a pair of fixed components, the locking bolt drives the lower pressure plate to restrict the degree of freedom of the deck in the Z-axis direction, the setting of the groove structure of the fixed seat, and the threaded screw pushes the limiting plate to restrict the degree of freedom of the deck in the XY-axis direction, thereby improving the stability of the deck during welding. At the same time, the range of motion of the lower pressure plate and the limiting plate can make the device adapt to the welding positioning of decks of different sizes.

[0013] (2) Two support plates are fixedly connected between a pair of transmission fixed seats to share the pressure borne by the fixed components when fixing the deck. At the same time, the two decks are on the same horizontal plane when they are close to each other, reducing the phenomenon of welding error caused by the different heights of the decks when they are close to each other by the bidirectional screw.

[0014] (3) The motor drives the gear to rotate, and the gear drives a pair of transmission fixed seats to rotate through the tooth chain, so that the device can be flipped over, thereby realizing double-sided welding of the deck. Attached Figure Description

[0026] Example 1:

[0027] This utility model provides a positioning device for welding ship decks. Please refer to [link / reference]. Figure 1-6 The system includes a base plate 1, with a pair of support seats 8 and a motor 13 fixedly connected to the upper surface of the base plate 1. Each of the support seats 8 has a rotating shaft 10 rotatably connected inside, and both ends of the rotating shaft 10 extend to the outside of the support seat 8. One end of each of the two rotating shafts 10 is fixedly connected to a transmission assembly 7. Two fixed assemblies 6 are slidably connected between the pair of transmission assemblies 7. One of the rotating shafts 10 is fixedly connected to a gear 9 at the end away from the transmission assembly 7. The output end of the motor 13 is fixedly connected to a gear 12. A toothed chain 11 meshes between gear 9 and gear 12. The pair of fixed assemblies 6 and the pair of transmission assemblies 7 cooperate to limit the movement of the deck 14, thereby achieving the clamping and fixing of decks of different sizes and improving the stability during welding.

[0028] Please see Figure 3 The transmission assembly 7 includes a transmission fixing seat 71, a bidirectional lead screw 72, and a pair of turntables 73. The transmission fixing seat 71 has a pair of rectangular through slots. The two ends of the fixing assembly 6 slide in the rectangular through slots on different transmission fixing seats 71. The left and right end faces of the transmission fixing seat 71 each have a circular through hole. The bidirectional lead screw 72 is rotatably connected in the circular through hole, and both ends of the lead screw 72 extend to the outside of the transmission fixing seat 71. The pair of turntables 73 are fixedly connected to the two ends of the bidirectional lead screw 72.

[0029] Please see Figure 4 The fixing component 6 includes a threaded screw 62, a lower pressure plate 63, a pair of locking bolts 64, multiple guide rods 65, and a fixing seat 66. The upper end face of the lower pressure plate 63 has two circular through holes 2. The upper end face of the fixing seat 66 has two threaded through holes 1 and multiple circular through holes 3. The two locking bolts 64 respectively movably pass through the pair of circular through holes 2 and are threadedly connected to the inside of the threaded through holes 1. One end of each of the multiple guide rods 65 is fixedly connected to the lower surface of the lower pressure plate 63 and is slidably connected to the inside of the multiple circular through holes 3, effectively guiding the lower pressure plate to move along a predetermined trajectory.

[0030] Please see Figure 4 The fixed base 66 has a threaded through hole 2 on one side. The threaded rod 62 is threaded into the threaded through hole 2, and both ends of the threaded rod 62 extend to the outside of the threaded through hole 2. A knob 61 is fixedly connected to one end of the threaded rod 62, and a baffle 67 is fixedly connected to the other end. The baffle 67 is located inside the fixed base 66. By restricting the degree of freedom of the deck 14 in the three directions of XYZ, it effectively improves the stability during welding and adapts to the positioning of decks of different sizes.

[0031] Please see Figure 3The two ends of the bidirectional lead screw 72 pass through a pair of fixed seats 66 and are threaded inside them. When the bidirectional lead screw 72 rotates in the forward direction, it causes the two decks 14 to move closer to each other. When it rotates in the reverse direction, it causes the decks 14 to move apart. The center of the bidirectional lead screw 72 has a reserved unthreaded structure to reduce the probability of the pair of fixed components 6 colliding with each other.

[0032] Please see Figure 1 A pair of support plates 5 are fixedly connected between a pair of transmission components 7. The support plates 5 and the fixed seat 66 in the fixed component 6 jointly support the two decks 14 and share the pressure borne by the fixed component 6 when fixing the decks 14. The upper surface of the pair of support plates 5 and the inner bottom surface of the fixed seat 66 are at the same level, which reduces the phenomenon of welding error caused by the different heights of the decks 14 when they come close to each other through the rotation of the bidirectional screw 72.

[0033] Working principle: Place one side of a deck 14 on the support plate 5 and align it with the groove of the fixing seat 66. Rotate the threaded screw 62 to push the baffle 67, thereby clamping the deck 14 between the inner wall of the groove of the fixing seat 66 and the baffle 67, thus initially fixing the deck 14. Then, press the lower pressure plate 63 to make it fit against the upper surface of the deck 14. Rotate the two locking bolts 64 to fix the lower pressure plate 63, thus fixing the deck 14 a second time. Use the same method to fix the other deck 14 to another fixing component 6. After fixing the two decks 14, rotate the turntables 73 at both ends of the bidirectional screw 72 to drive the pair of fixing components 6 and the two decks 14 to move closer to each other. After the end faces of the two decks 14 fit together, the upper end face of the deck 14 can be welded. After welding, start the motor 13 to drive the device to rotate and flip, so that the upper and lower end faces of the deck 14 are interchanged. Then, the deck 14 can be rotated to the upward-facing back side for welding.

[0034] Through the above operations, this application not only enables the device to weld and fix decks 14 of different sizes, but also enables double-sided welding of decks 14 without disassembling them, thus improving welding efficiency.

[0035] Example 2:

[0036] This embodiment adds the following to the first embodiment:

[0037] Please see Figure 1Multiple fixing plates 2 are fixedly connected to the upper end of the base plate 1. The fixed end of the electric telescopic rod 3 is fixedly connected to the upper end of the fixing plate 2. The output end of the electric telescopic rod 3 is fixedly connected to the support block 4. The model of the electric telescopic rod can be optimally selected by those skilled in the art according to the actual situation. For example, the LX835 model can be used. When the electric telescopic rod 3 reaches its maximum length, the upper end of the support block 4 is respectively attached to the lower surface of a pair of transmission fixing seats 71, which plays an auxiliary support role for the overall device.

[0038] During welding, the electric telescopic rod 3 is activated to push the support block 4 so that the upper end face of the support block 4 is in contact with the lower surface of the transmission fixed seat 71 to provide auxiliary support for the device. After the upper end face of the deck 14 is welded, the electric telescopic rod 3 is retracted to the minimum position. After the device is flipped, the electric telescopic rod 3 is restarted to provide auxiliary support for the device.

[0039] Compared with Example 1, this example adds the above-mentioned content, which can provide auxiliary support for the overall device when welding decks of different sizes on both sides, effectively improving the stability of the deck during welding.

[0040] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
