Description

Technical Field

[0001] The invention relates to the technical field of anchor chain processing, in particular to an automatic welding device for ship anchor chains and a method thereof. Background Art

[0002] Ship anchor chains work in harsh marine environments for a long time, and are subjected to huge tension and corrosion. Therefore, wear and breakage are inevitable. In order to ensure the safe navigation of the ship and the normal use of the anchor chain, the broken anchor chain must be repaired in time. Ship anchor chain welding is an important process in ship manufacturing and maintenance. Especially when the anchor chain is broken or a new anchor chain needs to be connected, welding becomes the main repair and connection method, and plays an important role in ship anchor chain repair.

[0003] For example, the patent number disclosed in the China Patent Network is: CN117506210B, and the patent name is: A ship anchor chain automatic welding device, including a track plate, a base plate, a side plate, an alignment part and a welding mechanism. The two U-shaped plates 1 and 2 provided in the present invention cooperate with each other to limit the metal rings therein, so the two adjacent metal rings are both limited and fixed and are kept parallel to the U-shaped plate 1 or the U-shaped plate 2, which is convenient for the subsequent placement of the horizontal axis into the annular area of ​​the metal ring, improving the stability during the welding process, and facilitating the horizontal axis to maintain full contact with the metal ring before welding, and making the horizontal axis and the straight line segment of the metal ring perpendicular to each other, avoiding the problem of a smaller contact area between the metal ring and the horizontal axis due to the offset of the metal ring, which in turn leads to a lower overall strength of the metal ring after welding.

[0004] However, the existing welding equipment first needs to position the chain links that are connected to each other to form the anchor chain. During the welding process, the chain links themselves are prone to deflection at a certain angle, which will interfere with the welding process. At the same time, the placement stability of the chain links must be ensured during welding, and the chain links and the welding gun must be in sufficient contact to ensure the strength of the anchor chain after welding. However, it is difficult to complete the above operations by manual welding.

[0005] In addition, due to the large number of metal rings in the anchor chain and the fact that two adjacent metal rings are not tightened, the weld overlap is incomplete or the weld direction is uneven during welding, which in turn affects the quality and strength of the welded joint. Incomplete welding will lead to unqualified weld quality, which will directly affect the strength after welding and the bearing capacity of the anchor chain.

[0006] Finally, in order to ensure the stability of the connection between the sleeved chain link and the welding gun, the placement angle of each chain link needs to be manually controlled during the welding process to make it perpendicular to the welding gun. Repeated rotation of the anchor chain will change the welding posture, resulting in the relative position of the welding gun and the weld to change continuously during the welding process. In addition, repeated rotation of the anchor chain requires additional operating steps and time, which increases the complexity of the welding process.

[0007] Therefore, it is necessary to design and transform the automatic welding equipment and method for ship anchor chains. Summary of the Invention

The number of claws is two and they are symmetrically arranged on both sides of the anchor chain. The inner sides of the claws are in contact with each other and form a closed loop surrounding the surface of the anchor chain.

[0015] Preferably, in the present invention, the linkage structure includes a crank pivotally connected to the top of the screw sleeve through a pin shaft. One side of the crank away from the screw sleeve is pivotally connected with a linkage rod through a pin shaft. The linkage rod is located at the bottom of the support plate and is fixedly connected with the support plate. During the process of the screw sleeves moving towards each other, the distance between the ends of the crank close to the screw sleeve can be changed, and the support plate can be pushed to move horizontally by using the linkage rod.

[0016] Preferably, in the present invention, the rotating assembly includes a toothed plate fixedly connected to the top of the base. The surface of the support plate is pivotally connected with a toothed ring located in front of the toothed plate through a bearing. The toothed ring and the toothed plate are meshed with each other.

[0020] An automatic welding equipment and method for ship anchor chains, comprising the following steps:

[0021] S1: Initial state: The anchor chain is placed on the top of the base, ready for welding. The welding torch assembly in the welding structure is located above the anchor chain. The clamping plates in the fixing structure are in an open state. The jaws on one side of the anchor chain are closed and form a closed loop sleeved on the surface of the anchor chain.

[0022] S2: The drive motor is started, driving the bidirectional screw in the connecting frame to rotate. The nut sleeve moves horizontally on the bidirectional screw, squeezing the swing rod through the slide rod, causing the clamping plates to swing around the shaft rod and clamp both sides of the anchor chain. The welding torch assembly works and processes the anchor chain.

[0023] S3: When a single section of the anchor chain is processed, the drive motor drives the nut sleeve to run in the reverse direction, causing the clamping plates to disengage from the anchor chain. While the nut sleeve is moving, the crank at the top of the nut sleeve pushes the support plate horizontally through the linkage rod, and the support plate drives the traction structure to pull the anchor chain.

[0024] S4: During the movement of the support plate, the toothed ring in the rotating assembly meshes with the toothed plate, causing the toothed ring to rotate. The toothed ring transmits the rotational force to the bearing plate through the helical gear, causing the jaws clamping the adjacent links of the anchor chain to swing from the horizontal state to the vertical state.

[0025] S5: During the continuous opening of the clamping plates, the shaft rod rotates with the swing of the clamping plates, driving the rotating wheel and the transmission rod to rotate. During the movement of the transmission rod, it squeezes the sleeve plate, and the extension rod connected to the sleeve plate drives the pressing plate to move inward and press the anchor chain.

[0026] S6: When the pressing plate finishes fixing, the continuously moving nut sleeve changes the distance inside the crank and uses the support plate to control the traction structure to change the relative setting with the anchor chain. At the same time, the traction structure controls the opening and closing of the jaws and fixes and pulls the subsequent links forming the anchor chain.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. By setting a welding structure with a fixing structure, the present invention can accurately weld the welds on the surface of the anchor chain. The direct contact design of the welding torch assembly ensures the welding quality, improves the welding efficiency and precision. The equipment realizes the automatic welding process of ship anchor chains through the integration of the base, welding structure, fixing structure, transmission structure, traction structure and linkage structure. This integrated design improves the production efficiency, reduces manual intervention, and ensures the welding quality and safety.

[0029] 2. Through the combination of the cross beam, bracket, shaft rod and clamping plates, the present invention realizes the reliable fixation of both sides of the anchor chain. The swing design of the clamping plates makes the fixation process more flexible, can adapt to anchor chains with different diameters and lengths, and improves the versatility and adaptability of the equipment.

[0030] 3. Through the cooperation of the bidirectional screw, drive motor, screw sleeve, swing rod and sliding rod, the present invention realizes the precise control of the clamping plate. The horizontal movement of the screw sleeve squeezes the swing rod through the sliding rod, thereby driving the clamping plate to swing, completing the clamping and release of the anchor chain, simplifying the transmission mechanism, and improving the transmission efficiency and precision.

[0031] 4. Through the combination of the support plate, rotating assembly, bearing plate, connecting block, stepping motor and claw, the present invention realizes the tensioning and conveying of the anchor chain. The closed-loop design of the claw ensures the stability of the anchor chain during the welding process. At the same time, the precise control of the stepping motor makes the clamping and release of the claw more accurate and reliable, improves the automation degree of the welding process, and reduces manual operation.

[0032] 5. Through the cooperation of the crank and the linkage rod, the present invention realizes the synchronous movement between the transmission structure and the traction structure. When the screw sleeves move towards each other, the crank changes the distance and pushes the support plate to move horizontally through the linkage rod, thereby driving the traction structure to pull and tension the anchor chain. At the same time, the change in the distance between the cranks can flexibly control the moving direction of the support plate.

[0033] 6. By setting the toothed plate, toothed ring and helical gear, the present invention realizes the adjustment of the angle of the anchor chain. During the movement of the support plate, the toothed ring meshes with the toothed plate and rotates, and the rotational force is transmitted to the bearing plate and the claw through the helical gear, enabling the claw to drive the anchor chain to swing from a horizontal state to a vertical state, improving the flexibility of the equipment, and enabling the anchor chain to maintain the best angle and position during the welding process.

[0034] 7. By setting the pressing plate, extension rod and sleeve plate, the present invention can squeeze and fix the anchor chain when the clamping plate is disengaged from the anchor chain, ensuring the stability of the anchor chain during the conveying process, avoiding welding interruption or quality problems caused by the movement of the anchor chain, and preventing the phenomenon of the natural drooping of the anchor chain when the traction structure is disengaged from the anchor chain.

[0035] 8. By setting the runner and transmission rod, the present invention realizes the precise control of the pressing plate. When the shaft rod rotates, the runner drives the transmission rod to slide inside the sleeve plate, thereby pushing the sleeve plate and the pressing plate to move inward and squeeze and fix the anchor chain, saving the operation steps of additionally setting transmission equipment, and can perform automatic positioning when the clamping plate is disengaged from the clamping state.

[0036] 9. By setting the guide bar, the present invention can limit the screw sleeve, avoiding the phenomenon of the screw sleeve tilting during the movement. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] As Figures 1 to 8 shown, a ship anchor chain automatic welding device and method provided by the present invention include a base 1;

[0048] An anchor chain 2 arranged on the top of the base 1, and the anchor chain 2 is composed of a plurality of chain links sleeved with each other;

[0049] The top of the base 1 is provided with a welding structure 3, which can weld the anchor chain 2. The welding structure 3 includes a frame 4 fixedly connected to the top of the base 1. On one side of the frame 4 away from the base 1, a welding torch assembly 5 is fixedly connected. The welding torch assembly 5 is located at the top of the anchor chain 2 and contacts the weld on the surface of the anchor chain 2. The welding structure 3 further includes a fixing structure 6 arranged on the top of the base 1. The fixing structure 6 is located on both sides of the anchor chain 2 and can fix the anchor chain 2. On the top of the base 1, a transmission structure 7 is arranged on one side of the fixing structure 6. The transmission structure 7 can drive the fixing structure 6 to open and close. On the top of the base 1, a traction structure 8 is arranged. The traction structure 8 can tension the anchor chain 2. On the surface of the transmission structure 7, a linkage structure 9 is arranged. The linkage structure 9 can push the traction structure 8 to pull the anchor chain 2 during the operation of the transmission structure 7.

[0050] Reference Figure 3 , the fixing structure 6 includes a cross beam 10 fixedly connected inside the base 1. On both sides of the top of the cross beam 10, brackets 11 are fixedly connected. Inside the brackets 11, a shaft rod 12 is movably connected. On the surface of the shaft rod 12, a clamping plate 13 is fixedly connected on one side of the bracket 11. The side of the clamping plate 13 away from the shaft rod 12 extends to the outside of the anchor chain 2 and contacts the surface of the anchor chain 2. The transmission structure 7 is fixedly connected to the surface of the bracket 11. The transmission structure 7 can drive the clamping plate 13 to swing. Inside the clamping plate 13, a rubber pad is arranged. The rubber pad has elasticity. The inner side of the rubber pad contacts the surface of the anchor chain 2.

[0051] As a technical optimization scheme of the present invention, through the combination of the cross beam 10, the brackets 11, the shaft rod 12 and the clamping plate 13, reliable fixation on both sides of the anchor chain 2 is achieved. The swing design of the clamping plate 13 makes the fixation process more flexible, can adapt to anchor chains 2 with different diameters and lengths, and improves the versatility and adaptability of the equipment.

[0052] Reference Figure 3 , the transmission structure 7 includes a connection frame 14 fixedly connected to the surface of the bracket 11. Inside the connection frame 14, a bidirectional screw 15 is movably connected through a bearing. On the front of the connection frame 14, a transmission motor 16 for driving the bidirectional screw 15 to rotate is fixedly connected. On both sides of the surface of the bidirectional screw 15, screw sleeves 17 are threadedly connected. On the side of the clamping plate 13 close to the bracket 11, a swing rod 18 is fixedly connected. The swing rod 18 is horizontally arranged on one side of the screw sleeve 17. On the surface of the screw sleeve 17, a sliding rod 19 is fixedly connected inside the swing rod 18. During the horizontal movement of the screw sleeve 17, the sliding rod 19 can squeeze the swing rod 18 to swing. On the surface of the connection frame 14, a guiding plate is fixedly connected on one side of the bidirectional screw 15. The guiding plate can support the processed and naturally hanging anchor chain 2 to prevent the anchor chain 2 from colliding with the bidirectional screw 15.

[0053] As a technical optimization solution of the present invention, through the cooperation of the bidirectional screw 15, the drive motor 16, the screw sleeve 17, the swing rod 18 and the slide rod 19, the precise control of the clamping plate 13 is realized. The horizontal movement of the screw sleeve 17 squeezes the swing rod 18 through the slide rod 19, and then drives the clamping plate 13 to swing, completing the clamping and release of the anchor chain 2, simplifying the transmission mechanism, and improving the transmission efficiency and accuracy.

[0054] Reference Figure 5 , the traction structure 8 includes a support plate 20 installed on the surface of the transmission structure 7 through a linkage structure 9. The top of the support plate 20 is provided with a bearing plate 22 through a rotating assembly 21. A connecting block 23 is fixedly connected to the surface of the bearing plate 22. The rotating assembly 21 can drive the anchor chain 2 to change the placement angle when the traction structure 8 pulls the anchor chain 2. A stepping motor 24 is fixedly connected to the surface of the connecting block 23. The output end of the stepping motor 24 is fixedly connected to a claw 25 located inside the connecting block 23. The number of claws 25 is two and they are symmetrically arranged on both sides of the anchor chain 2. The inner sides of the claws 25 are in contact with each other and form a closed loop surrounding the surface of the anchor chain 2.

[0055] As a technical optimization solution of the present invention, through the combination of the support plate 20, the rotating assembly 21, the bearing plate 22, the connecting block 23, the stepping motor 24 and the claw 25, the tensioning and conveying of the anchor chain 2 are realized. The closed-loop design of the claw 25 ensures the stability of the anchor chain 2 during the welding process. At the same time, the precise control of the stepping motor 24 makes the clamping and release of the claw 25 more accurate and reliable, improving the automation degree of the welding process and reducing manual operation.

[0056] Reference Figure 4 , the linkage structure 9 includes a crank 26 movably connected to the top of the screw sleeve 17 through a pin shaft. One side of the crank 26 away from the screw sleeve 17 is movably connected to a linkage rod 27 through a pin shaft. The linkage rod 27 is located at the bottom of the support plate 20 and is fixedly connected to the support plate 20. During the opposite movement of the screw sleeves 17, the distance between the ends of the crank 26 close to the screw sleeves 17 can be changed, and the support plate 20 can be pushed to move horizontally by using the linkage rod 27. The crank 26 is usually made of high-strength and wear-resistant metal materials, such as alloy steel or stainless steel. The distance between the cranks 26 is related to the moving distance of the support plate 20.

[0057] As a technical optimization solution of the present invention, through the cooperation of the crank 26 and the linkage rod 27, the synchronous movement between the transmission structure 7 and the traction structure 8 is realized. When the screw sleeves 17 move towards each other, the distance between the cranks 26 changes, and the support plate 20 is pushed to move horizontally through the linkage rod 27, thereby driving the traction structure 8 to pull and tension the anchor chain 2. At the same time, the change in the distance between the cranks 26 can flexibly control the moving direction of the support plate 20.

[0058] Reference Figure 5, the rotating assembly 21 includes a toothed plate 28 fixedly connected to the top of the base 1. The surface of the support plate 20 is movably connected by a bearing with a toothed ring 29 located in front of the toothed plate 28. The toothed ring 29 and the toothed plate 28 mesh with each other. Both the bearing plate 22 and one end of the toothed ring 29 close to the support plate 20 penetrate through the support plate 20 and are movably connected to the support plate 20 by bearings. One end of the connecting block 23 and the toothed ring 29 that penetrate through the support plate 20 are fixedly connected with helical gears 30. The helical gears 30 mesh with each other. During the horizontal movement of the support plate 20, the toothed ring 29 is pushed to rotate through the meshing state with the toothed plate 28, and the torque is transmitted to the claw 25 by using the helical gears 30. The number of meshing teeth between the toothed plate 28 and the toothed ring 29 is associated with the rotation angle of the claw 25.

[0059] As a technical optimization scheme of the present invention, by setting the toothed plate 28, the toothed ring 29, and the helical gears 30, the adjustment of the angle of the anchor chain 2 is realized. During the movement of the support plate 20, the toothed ring 29 meshes with and rotates with the toothed plate 28, and the rotational force is transmitted to the bearing plate 22 and the claw 25 through the helical gears 30, so that the claw 25 can drive the anchor chain 2 to swing from the horizontal state to the vertical state, which can improve the flexibility of the equipment and enable the anchor chain 2 to maintain the best angle and position during the welding process.

[0060] Reference Figure 6 , a guide rod 31 is fixedly connected to the surface of the bracket 11. A sleeve plate 32 is sleeved on the surface of the guide rod 31. An extension rod 33 is fixedly connected to the inner side of the sleeve plate 32. One side of the extension rod 33 away from the sleeve plate 32 is fixedly connected with a pressing plate 34. The pressing plate 34 is located on both sides of the anchor chain 2 and can squeeze and fix the anchor chain 2 when the clamping plate 13 is disengaged from the anchor chain 2. A driving structure 35 is arranged on the surface of the bracket 11. The driving structure 35 can control the pressing plate 34 to close and squeeze and fix the anchor chain 2 during the opening process of the transmission structure 7.

[0061] As a technical optimization scheme of the present invention, by setting the pressing plate 34, the extension rod 33 and the sleeve plate 32, the anchor chain 2 can be squeezed and fixed when the clamping plate 13 is disengaged from the anchor chain 2, ensuring the stability of the anchor chain 2 during the conveying process, avoiding welding interruption or quality problems caused by the movement of the anchor chain 2, and avoiding the phenomenon that the anchor chain 2 naturally drops when the traction structure 8 is disengaged from the anchor chain 2.

[0062] Reference Figure 8 , the driving structure 35 includes a runner 36 fixedly connected to one end of the shaft rod 12 away from the clamping plate 13. A transmission rod 37 is fixedly connected to the surface of the runner 36. One side of the transmission rod 37 away from the runner 36 extends into the sleeve plate 32. The sleeve plate 32 is slidably connected with the transmission rod 37. A bending part is arranged at the top of the sleeve plate 32, and the bending angle of the bending part is the same as the rotation angle of the transmission rod 37.

[0063] As a technical optimization solution of the present invention, by setting the rotating wheel 36 and the transmission rod 37, precise control of the pressing plate 34 is achieved. When the shaft rod 12 rotates, the rotating wheel 36 drives the transmission rod 37 to slide inside the sleeve plate 32, thereby pushing the sleeve plate 32 and the pressing plate 34 to move inward and squeeze the fixed anchor chain 2, saving the operation steps of additionally setting transmission equipment, and automatic positioning can be performed when the clamping plate 13 is disengaged from the clamping state.

[0064] Reference Figure 3 , a guide bar 38 is fixedly connected inside the connecting frame 14. The guide bar 38 is located at the bottom of the bidirectional screw 15. One side of the guide bar 38 away from the connecting frame 14 extends into the inside of the screw sleeve 17, and the screw sleeve 17 is slidably connected to the guide bar 38.

[0065] As a technical optimization solution of the present invention, by setting the guide bar 38, the screw sleeve 17 can be limited, avoiding the phenomenon of the screw sleeve 17 tilting during movement.

[0066] Reference Figure 1 , an automatic welding device and method for ship anchor chains, including the following steps:

[0067] S1: Initial state: The anchor chain 2 is placed on the top of the base 1, ready for welding. The welding torch assembly 5 in the welding structure 3 is located above the anchor chain 2. The clamping plate 13 in the fixing structure 6 is in an open state, and the clamping claws 25 on one side of the anchor chain 2 are closed and form a closed loop sleeved on the surface of the anchor chain 2;

[0068] S2: The drive motor 16 is started, driving the bidirectional screw 15 in the connecting frame 14 to rotate. The screw sleeve 17 moves horizontally on the bidirectional screw 15, squeezing the swing rod 18 through the slide rod 19, causing the clamping plate 13 to swing around the shaft rod 12 and clamp both sides of the anchor chain 2. The welding torch assembly 5 works and processes the anchor chain 2;

[0069] S3: When a single section of the anchor chain 2 is processed, the drive motor 16 drives the screw sleeve 17 to run in the reverse direction, causing the clamping plate 13 to disengage from the anchor chain 2. While the screw sleeve 17 is moving, the crank 26 at the top of the screw sleeve 17 pushes the support plate 20 to move horizontally through the linkage rod 27, and the support plate 20 drives the traction structure 8 to pull the anchor chain 2;

[0070] S4: During the movement of the support plate 20, the toothed ring 29 in the rotating assembly 21 meshes with the toothed plate 28, causing the toothed ring 29 to rotate. The toothed ring 29 transmits the rotational force to the bearing plate 22 through the helical gear 30, causing the clamping claws 25 to clamp the adjacent link of the anchor chain 2 to swing from the horizontal state to the vertical state;

[0071] S5: During the continuous opening of the clamping plate 13, the shaft rod 12 swings and rotates along with the clamping plate 13, driving the rotating wheel 36 and the transmission rod 37 to rotate. During the movement of the transmission rod 37, it squeezes the sleeve plate 32, and the extension rod 33 connected to the sleeve plate 32 drives the pressing plate 34 to move inward and squeeze the fixed anchor chain 2;

[0072] S6: When the pressing plate 34 finishes fixing, the continuously moving screw sleeve 17 changes the distance inside the crank 26 and uses the support plate 20 to control the traction structure 8 to change the relative setting with the anchor chain 2. At the same time, the traction structure 8 controls the opening and closing of the claw 25 and fixes and pulls the subsequent chain links forming the anchor chain 2.

[0073] The working principle and use process of the present invention are as follows: an anchor chain 2 is arranged on the top of the equipment base 1, and a welding structure 3 is installed above the anchor chain 2, including a frame 4 and a welding gun assembly 5 fixed on the top of the base 1. The welding gun assembly 5 is directly aligned with the weld on the surface of the anchor chain 2 for welding. At the same time, a fixing structure 6 is arranged on the base 1, which is composed of a crossbeam 10, a bracket 11, an axle rod 12 and a clamping plate 13. The clamping plate 13 moves in the bracket 11 through the axle rod 12, and can clamp the two sides of the anchor chain 2 for fixing. The transmission structure 7 drives the screw sleeve 17 to move horizontally through the bidirectional screw 15 and the transmission motor 16 in the connecting frame 14. The screw sleeve 17 drives the sliding rod 19 in the swing rod 18 to squeeze the clamping plate 13, so that the clamping plate 13 swings and clamps the anchor chain 2. In this process, the crank 26 on the screw sleeve 17 is linked The rod 27 pushes the support plate 20 to move horizontally, so that the support plate 20 carries the traction structure 8 to move to the side close to the anchor chain 2. When the claws 25 constituting the traction structure 8 move to the outside of the anchor chain 2, the stepper motor 24 drives the claws 25 to swing toward each other, so that the two claws 25 contact each other and form a closed loop sleeved on the surface of the anchor chain 2, which can pull the anchor chain 2 with the movement of the support plate 20 to achieve tension. When the anchor chain 2 located on the inner side of the clamping plate 13 is welded and needs to be further transported and fed, the two-way screw 15 and the transmission motor 16 in the connecting frame 14 drive the screw sleeve 17 to move horizontally in the opposite direction. The screw sleeve 17 uses the sliding rod 19 to squeeze the swing rod 18, so that the clamping plate 13 swings outward and breaks contact with the anchor chain 2. At the same time, the crank 26 on the surface of the screw sleeve 17 is The spacing is shortened and the shear force is used to push the support plate 20 to move to the side away from the clamping plate 13. During the movement of the support plate 20, the toothed ring 29 in the rotating assembly 21 is meshed with the toothed plate 28 on the base 1. When the support plate 20 moves, the toothed ring 29 is driven to rotate and the rotational force is transmitted to the bearing plate 22 through the bevel gear 30. The bearing plate 22 uses the connecting block 23 to carry the claw 25 to rotate, so that the subsequent section of the anchor chain 2 fixed by the claw 25 is swung from a horizontal state to a vertical state, and the shaft 12 installed on the surface of the clamping plate 13 can drive the rotating wheel 36 to rotate synchronously during the process of following the swinging rotation. The rotating wheel 36 drives the transmission rod 37 to slide inside the sleeve plate 32. The sleeve plate 32 is squeezed and uses the extension rod 33 to drive the pressure plate 34 to move inward. When the inner When the side contacts the surface of the anchor chain 2 and the crank 26 swings from the outward inclined state to a parallel state, the pressure plate 34 can squeeze and fix the anchor chain 2, and at the same time, the stepper motor 24 drives the claw 25 to open and release the end of the anchor chain 2 clamped by the claw 25. At this time, the continuously moving screw sleeve 17 can carry the crank 26 to swing from a mutually horizontal state to an inward inclined state, and the crank 26 further shortens the distance and pulls the support plate 20 to reset. When the claw 25 on the surface of the support plate 20 moves to the outside of the anchor chain 2 squeezed and fixed by the pressure plate 34, the stepper motor 24 drives the claw 25 to close and clamp the subsequent section of the anchor chain 2. When the claw 25 is connected to the subsequent section of the anchor chain 2, the transmission motor 16 runs in the opposite direction and drives the above steps to flip.When the clamping plate 13 contacts and fixes the anchor chain 2, the welding torch assembly 5 operates to make the above steps form a cyclic processing.

[0074] In summary: For this automatic welding equipment and method for ship anchor chains, by setting the welding structure 3 carrying the fixing structure 6, it can accurately weld the welds on the surface of the anchor chain 2. The direct contact design of the welding torch assembly 5 ensures the welding quality, improves the welding efficiency and precision.
