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

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can accurately weld the weld on the surface of the anchor chain by providing a welding structure with a fixed structure. The direct contact design of the welding gun assembly ensures the welding quality and improves the welding efficiency and accuracy.

This integrated design improves production efficiency, reduces manual intervention, and ensures welding quality and safety.

[0020] 2. The present invention realizes reliable fixation of both sides of the anchor chain through the combination of the crossbeam, the bracket, the shaft rod and the clamping plate. The swinging design of the clamping plate makes the fixing process more flexible and can adapt to anchor chains of different diameters and lengths, thereby improving the versatility and adaptability of the equipment.

[0021] 3. The invention realizes precise control of the splint through the cooperation of the bidirectional screw, the transmission motor, the screw sleeve, the swing rod and the slide rod. The horizontal movement of the screw sleeve squeezes the swing rod through the slide rod, thereby driving the splint to swing, completing the clamping and release of the anchor chain, simplifying the transmission mechanism and improving the transmission efficiency and precision.

[0022] 4.

[0023] 5. The present invention realizes the synchronous movement between the transmission structure and the traction structure through the cooperation of the crank and the linkage rod. When the screw sleeves move toward each other, the cranks change the spacing and push 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 spacing between the cranks can flexibly control the moving direction of the support plate.

[0024] 6. The present invention realizes the adjustment of the anchor chain angle by setting a tooth plate, a tooth ring and a bevel gear. During the movement of the support plate, the tooth ring meshes and rotates with the tooth plate, and the rotational force is transmitted to the load-bearing plate and the claw through the bevel gear, so that the claw can drive the anchor chain to swing from a horizontal state to a vertical state, which can improve the flexibility of the equipment and enable the anchor chain to maintain the best angle and position during the welding process.

[0025] 7. The present invention provides a pressure plate, an extension rod and a sleeve plate, so that the anchor chain can be squeezed and fixed when the clamping plate is out of contact with the anchor chain, thereby ensuring the stability of the anchor chain during transportation, avoiding welding interruption or quality problems caused by the movement of the anchor chain, and avoiding the natural falling of the anchor chain when the traction structure is out of contact with the anchor chain.

[0026] 8. The present invention realizes precise control of the pressure plate by setting a rotating wheel and a transmission rod. When the shaft rotates, the rotating wheel drives the transmission rod to slide inside the sleeve plate, thereby pushing the sleeve plate and the pressure plate to move inward and squeeze and fix the anchor chain, saving the operating steps of setting up additional transmission equipment, and can automatically position when the clamping plate is out of the clamping state.

[0027] 9. The present invention can limit the screw sleeve by setting a guide strip to prevent the screw sleeve from tilting during movement. BRIEF DESCRIPTION OF THE DRAWINGS

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 is in contact with and fixed to the anchor chain 2, the welding gun assembly 5 is operated, so that the above steps form a cycle processing.

[0050] In summary: the ship anchor chain automatic welding equipment and method, by providing a welding structure 3 carrying a fixed structure 6, can accurately weld the weld on the surface of the anchor chain 2. The direct contact design of the welding gun assembly 5 ensures the welding quality and improves the welding efficiency and accuracy.
