Description

Technical Field

[0001] The present invention relates to the field of welding technology, and specifically relates to a welding device for a drum protective cover of a marine anchor winch. Background Art

[0002] A marine anchor winch is a mechanical device used to control the anchor of a ship and is widely used in various types of ships, including merchant ships, fishing boats, yachts, etc. Its main function is to lift and lower the anchor and pay out and take in the anchor chain to ensure the stability and safety of the ship when it is berthed, as shown in Figure 1 As shown, the drum protective cover of the marine anchor winch is first processed into a semi-finished state through a bending process. At this time, one side edge of the drum protective cover needs to be welded and sealed with the other side edge by a welding machine.

[0003] After retrieval, the existing patent number CN118253872B discloses a container frame welding device, including a base, on which an auxiliary component and a positioning component are arranged. The auxiliary component includes a laser welding head and a finger clamping cylinder. The laser welding head is used to weld the container frame, and the finger clamping cylinder is used to clamp the connecting rod. By setting the auxiliary component, the connecting rod can be moved to be joined with the frame rod without manual operation, and the two ends of the connecting rod can be automatically welded to the connection part of the frame rod. By setting the positioning component, the positioning and fixing of 4 frame rods can be completed at one time, and the distance between two adjacent frame rods can be adjusted according to requirements. Through the mutual cooperation of the auxiliary component and the positioning component, the connection of the frame rod and the connecting rod of the container frame can be realized at one time without a secondary component, greatly improving the welding quality and stability of the container frame.

[0004] The existing frame welding device has a relatively simple structure. When welding, since the included angle between the side edge to be welded and sealed and the adjacent side edge of the protective cover is an obtuse angle after bending, it is still necessary to manually assist in pressing down the side edge to be welded and sealed so that this side edge is in a horizontal state or aligned with the other side edge. Then, the welding head module in the welding device is used to weld and fix the two side edges, and finally, it is taken down manually. During the whole welding process, not only can it not automatically load, clamp, and unload, but also it cannot automatically flatten and align the side edge that needs to be welded and sealed.

[0049] Please refer to Figure 4 and Figure 16 , further, the first transmission assembly 12 further includes a first L-shaped plate 124, a first limiting rod 125, a second limiting rod 126 and a limiting rib 127. The first L-shaped plate 124 is movably sleeved on the surface of the collar 123. The first limiting rod 125 and the second limiting rod 126 are both fixedly connected to the first L-shaped plate 124. The limiting rib 127 is arranged on the surface of the second limiting rod 126. The second limiting rod 126 is movably sleeved in the central tube 43.

[0050] Please refer to Figure 16 , further, a plurality of limiting holes 34 are arranged on the surface of the L-shaped frame 31. A limiting groove 431 is arranged on the inner wall of the central tube 43.

[0051] Please refer to Figure 12 and Figure 16 , further, the second transmission assembly 42 includes a first transmission gear 421, a first synchronous pulley 422, a synchronous belt 423 and a second synchronous pulley 424. The first transmission gear 421 and the first synchronous pulley 422 are coaxially connected to the surface of the arc-shaped side plate 22. The second synchronous pulley 424 is fixedly connected to the central tube 43. The synchronous belt 423 is connected between the first synchronous pulley 422 and the second synchronous pulley 424. The driving gear 121 can be in transmission connection with the first transmission gear 421.

[0052] In the embodiment of the present invention, when the electromagnet 24 is attached to the magnetic sheet 128, the driving gear 121 is in driving connection with the tooth groove 33, the first limiting rod 125 disengages from the limiting hole 34, the limiting rib 127 slides into the limiting groove 431. When the first return spring 28 drives the first L-shaped plate 124 to fit against the surface of the limiting frame 25, the driving gear 121 is in driving connection with the first transmission gear 421, the first limiting rod 125 enters the limiting hole 34, and the limiting rib 127 disengages from the limiting groove 431. During this process, the first limiting rod 125 always penetrates the surface of the limiting frame 25.

[0053] Working principle: Refer to the appendix Figure 13 , first place the cover body 7 on the surface of the feeding rack 41. It should be noted that the side of the cover body 7 that needs to be welded and sealed is away from the support plate 47. One side of the second L-shaped plate 44 is in contact with the inner side of the cover body 7 to prevent the cover body 7 from rebounding and deforming. Then, control the electromagnet 24 to power off. Since the electromagnet 24 after power-off loses the magnetic attraction force on the magnetic sheet 128, the first return spring 28 drives the first L-shaped plate 124 to fit against the surface of the limiting frame 25. At this time, the driving gear 121 is in driving connection with the second transmission assembly 42, and the first limiting rod 125 enters the limiting hole 34 to longitudinally limit the welding mechanism, and the limiting rib 127 disengages from the limiting groove 431;

[0054] Refer to the appendix Figure 14 , then control the driving motor 111 to drive the driving gear 121 to rotate through the driving square rod 112. The rotating driving gear 121 controls the feeding rack 41, the clamping assembly 5, and the flattening assembly 6 to rotate 90 degrees around the central tube 43 as the axis towards the direction close to the welding head module 32 through the first transmission gear 421. During this process, the second transmission gear 62 in the flattening assembly 6 controls the rotation of the threaded tube 61 by being in driving connection with the arc-shaped tooth rail 27. The rotating threaded tube 61 drives the pressing plate 64 to move through the threaded rod 63. The moving pressing plate 64 can squeeze one side of the cover body 7 to be welded and sealed. On the one hand, it can ensure that the cover body 7 fits against the support plate 47, and on the other hand, it can ensure that one side of the cover body 7 to be welded and sealed fits against the other side of the second L-shaped plate 44, so as to ensure that the cover body 7 is in a pre-closed state, facilitating the next welding operation. When the tapered block 52 in the clamping assembly 5 slides into contact with the trapezoidal platform 26 until it stops, the trapezoidal platform 26 can drive the tapered block 52 to displace along the axis of the sliding rod 53, and then drive the clamping plate 51 to squeeze the cover body 7 towards the second L-shaped plate 4 to ensure that one side of the cover body 7 to be welded and sealed is aligned with the other side edges;

[0055] Continue to refer to the appendix Figure 14, then the electromagnet 24 is controlled to be energized. When the energized electromagnet 24 is attached to the magnetic sheet 128, the driving gear 121 is connected to the tooth groove 33, the first limiting rod 125 is separated from the limiting hole 34, and the limiting rib 127 slides into the limiting groove 431 to prevent the unloading rack 41 from shaking. The driving motor 111 controls the L-shaped rack 31 to descend through the driving gear 121 and the tooth groove 33 until the welding head module 32 contacts the side of the cover body 7 to be welded and sealed, and the welding head module 32 is used to weld the side to be welded and sealed with the other side edges, and the power of the driving motor 1 is used to drive the welding head module 32 to rise and reset;

[0056] Reference Figure 15 After welding is completed, continue to control the electromagnet 24 to cut off the power. According to the above operation method, use the power of the drive motor 1 to drive the unloading rack 41 to continue to rotate 90 degrees. During this process, since the conical block 52 is gradually separated from the trapezoidal platform 26, the elastic deformation of the second return spring 54 controls the clamping plate 51 to separate from the cover body 7. At this time, the cover body 7 can automatically complete the unloading.

[0057] To summarize, the present application utilizes a structural design in which a driving mechanism 1, a bearing mechanism 2, a welding mechanism 3, a rotating mechanism 4, a clamping assembly 5 and a flattening assembly 6 cooperate with each other, which can not only automatically fix the cover body 7 during the automatic loading process and ensure that one side of the cover body 7 to be welded and sealed fits with the other side of the second L-shaped plate 44 without manual assistance to press the side of the cover body 7 to be welded and sealed, but also automatically cancel the clamping of the cover body 7 during the automatic unloading process after welding is completed, so that the cover body 7 can automatically fall off under the action of gravity, and has the characteristics of clever structural coordination, no need for manual assistance to press the cover body 7 and high work efficiency.

These new embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the scope of the main purpose of the invention.
