Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a ship functional section welding mechanism. Background Technology

[0002] Ships are a general term for all kinds of vessels. They are means of transportation that can navigate or anchor in waterways for transport or operations. Depending on the specific requirements, they possess different technical specifications, equipment, and structural forms. Ships have a large overall structure and volume, with numerous parts. During production, they are manufactured in sections and then assembled by welding. However, due to the challenges in joining certain plates:

[0003] For example, when welding two perpendicular plates, the weld seams may be difficult to align, resulting in poor weld quality. If the two plates are not perfectly aligned at the joint during assembly and welding, and the gap between them is not completely flat and has some imperfections, the solder may not be able to completely fill the joint during the welding process, leading to false welds and later detachment. The same problem will also occur when welding irregularly shaped plates, as it is difficult to clamp and fix them.

[0004] Therefore, a segmented welding mechanism for shipboard applications is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a ship section welding mechanism. The utility model provides the following technical solution, including:

[0006] The base is L-shaped and has symmetrical clamping components. One end of the base has a fixing component, and one side of the base has a sliding seat. A welding arm is slidably mounted on the sliding seat, and one end of the welding arm has a welding head.

[0007] Furthermore, the clamping assembly includes;

[0008] An upper clamping block is rotatably mounted at the top of the vertical section of the base. A connecting rod is slidably mounted through the upper end of the clamping block. A telescopic cylinder is mounted at the top of the upper clamping block, and its telescopic end is connected to one end of the connecting rod. The other end of the connecting rod is rotatably connected to the upper end of one end of the lower pressing block. The lower pressing block is C-shaped, and the other end of the lower pressing block is rotatably connected to the side wall of the base.

[0009] Furthermore, the fixing component includes:

[0010] The fixed shell has guide rail blocks on both sides, and a first guide rail groove on each guide rail block. A sliding rod is provided on the inner side of one end of the pressing block, and the sliding rod is slidably disposed in the first guide rail groove. A second guide rail groove is symmetrically provided on both sides of the bottom of the fixed shell. A limiting slider corresponding to the second guide rail groove is provided on the side of the horizontal section of the base. A limiting mechanism is provided at the front end of the fixed shell.

[0011] Furthermore, the limiting mechanism includes: a U-shaped groove formed in the middle of the inner cavity of the fixed shell, a plurality of balls corresponding to its size are provided in the U-shaped groove, and top blocks are provided at both ends of the U-shaped groove, the top blocks passing through and slidingly disposed at the front end of the fixed shell.

[0012] Furthermore, a limiting rod is provided above the front end of the fixed shell, and the limiting rod penetrates vertically through the top of the fixed shell and is inserted to the upper part of the middle of the top block.

[0013] Furthermore, the upper clamping block, lower pressing block, and top block are all covered with a rubber layer.

[0014] Furthermore, the welding arm forms a 45-degree angle with the sliding seat.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] This utility model integrates clamping and fixing components through an L-shaped base to achieve stable positioning for vertical plate segment welding. Combined with the flexible adjustment of the sliding seat and welding arm, it adapts to the operational needs of complex joints in ship segment welding and solves the problem of weld misalignment caused by the instability of traditional manual clamping.

[0017] The upper clamping block in the clamping assembly is driven by a telescopic cylinder to form an adjustable progressive clamping force. Combined with the rotating connection design, it can adapt to the thickness difference of the plate in the vertical direction, with a clamping accuracy of ±0.2mm. This effectively prevents the problem of false welding caused by plate displacement during welding. At the same time, the connecting rod links the lower C-shaped pressing block to press down and clamp the plate in the horizontal direction. Simultaneously, it drives the fixing assembly to clamp the irregular surface of the plate in the horizontal direction. The ball bearings in the U-shaped groove push the top block forward to clamp. The top block and the limit plug form a quick lock to ensure the fixed stability of the irregular panel. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 The technical solution provided by this utility model is: a ship section welding mechanism, comprising:

[0026] The base 1 is L-shaped. Two plates for segmented welding are placed perpendicularly on the base 1. The base 1 is symmetrically provided with clamping components 2. One end of the base 1 is provided with a fixing component 3. One side of the base 1 is provided with a sliding seat 4. A welding arm 5 is slidably provided on the sliding seat 4. One end of the welding arm 5 is provided with a welding head 6.

[0027] By integrating clamping and fixing components 3 into the L-shaped base 1, stable positioning of vertical plate segment welding is achieved. Combined with the flexible adjustment of the sliding seat 4 and welding arm 5, it can meet the operational needs of complex joints in ship segment welding and solve the problem of weld misalignment caused by the instability of traditional manual clamping.

[0028] In a preferred embodiment, the clamping component 2 includes:

[0029] An upper clamping block 21 is rotatably mounted at the top of the vertical section of the base 1. A connecting rod 22 is slidably mounted through the upper end of the clamping block 21. A telescopic cylinder 23 is mounted at the top of the upper clamping block 21. Its telescopic end is connected to one end of the connecting rod 22. The other end of the connecting rod 22 is rotatably connected to the upper end of one end of the lower pressing block 24. The lower pressing block 24 is C-shaped. The other end of the lower pressing block 24 is rotatably connected to the side wall of the base 1.

[0030] In the clamping assembly 2, the upper clamping block 21 is driven by the telescopic cylinder 23 to form an adjustable progressive clamping force. Combined with the rotating connection design, it can adapt to the thickness difference of the plate in the vertical direction and clamp with a clamping accuracy of ±0.2mm. This effectively prevents the false welding problem caused by plate displacement during the welding process. At the same time, the connecting rod 22 is linked with the lower C-shaped pressing block 24 to press down and clamp the plate in the horizontal direction.

[0031] In a preferred embodiment, the fixing component 3 includes:

[0032] The fixed shell 31 has guide rail blocks 32 on both sides, and a first guide rail groove 33 on the guide rail blocks 32. A sliding rod 34 is provided on the inner side of one end of the pressing block 24, and the sliding rod 34 is slidably disposed in the first guide rail groove 33. The bottom of the fixed shell 31 has symmetrical second guide rail grooves 35 on both sides. The horizontal section of the base 1 has a limiting slider 36 corresponding to the second guide rail groove 35 on its side. The front end of the fixed shell 31 has a limiting mechanism.

[0033] The pressing block 24 in the clamping assembly 2 drives the slide bar 34 to move to the top of the first guide rail groove 33 and simultaneously drives the fixing assembly 3 to move through the limiting slider 36 and the second guide rail groove 35 to clamp the irregular surface of the plate in the horizontal direction.

[0034] In a preferred embodiment, the limiting mechanism includes: a U-shaped groove formed in the middle of the inner cavity of the fixed shell 31, a plurality of balls 371 of corresponding size are provided in the U-shaped groove, and top blocks 372 are provided at both ends of the U-shaped groove. The top blocks 372 are slidably disposed at the front end of the fixed shell 31; a limiting rod 373 is also provided above the front end of the fixed shell 31, and the limiting rod 373 is perpendicularly inserted through the top of the fixed shell 31 and inserted above the middle of the top blocks 372.

[0035] The ball bearings 371 within the U-shaped groove push the top block 372 forward to clamp it. The arrangement of several ball bearings 371 effectively balances the extension and clamping of the two top blocks 372 at the front end of the fixed shell 31. The top block 372 and the limiting rod 373 form a quick lock, ensuring the stability of the irregularly shaped panel. The limiting rod 373 enhances the stability of the fixation through mechanical locking, can withstand welding vibration loads, and prevents the irregularly shaped panel from shifting due to vibration during the welding process.

[0036] In this preferred embodiment, the upper clamping block 21, the lower pressing block 24, and the top block 372 are all covered with a rubber layer. The rubber layer provides anti-slip protection, preventing damage to the surface of the sheet material during clamping, and is especially suitable for welding easily scratched materials such as aluminum alloys and stainless steel.

[0037] In this preferred embodiment, the welding arm 5 and the sliding seat 4 form a 45-degree angle.

[0038] The 45° tilt design allows the welding head 6 to achieve the optimal welding angle, which, combined with the linear movement of the sliding seat 4, enables full-position welding coverage and improves welding efficiency.

[0039] Working principle:

[0040] Vertical and horizontal sections of the plate are fixed and clamped: The telescopic cylinder 23 retracts, which drives the connecting rod 22 to retract, which drives the C-shaped lower pressure block 24 to rotate around the side wall of the base 1, forming a vertical clamping force on the horizontal plate. At the same time, the upper clamping block 21 rotates synchronously due to the lever principle to clamp the vertical plate.

[0041] Irregular surface clamping: The inner slide bar 34 of the lower pressure block 24 slides along the first guide rail groove 33 to the top, pushing the fixed shell 31 to move horizontally through the second guide rail groove 35 and the limiting slider 36 to complete the interlocking clamping of the irregular plate edge: The ball 371 in the U-shaped groove rolls under the clamping pressure, pushing the top blocks 372 on both sides to extend outward, automatically compensating for the gap between the irregular surface of the plate and the clamping surface; the limiting rod 373 is inserted into the middle of the top block 372 to form a limiting constraint; the welding arm 5 moves horizontally along the base 1 with a 45° tilt angle as the reference, and drives the welding head 6 to perform full welding at the junction of the vertical plate and the horizontal plate. After welding, the telescopic cylinder 23 extends, driving the clamping component 2 and the fixing component 3 to release the clamping.

[0042] This utility model forms an orthogonal constraint between the vertical clamping component 2 and the horizontal fixing component 3, which greatly reduces the misalignment of the plate joints; the linkage design of the ball bearing 371 and the top block 372 enables the fit of irregularly shaped panels to reach 98%, improving the weld filling rate; the limiting rod 373 and the rubber layer provide double vibration reduction, reducing the amplitude of the welding head 6 to ±0.05mm, eliminating the risk of false welding.

[0043] The parts not covered in this utility model are the same as or can be implemented using existing technologies.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
