Description

[0002] Marine anchor winch is a mechanical device used to control the anchor of a ship. It is widely used in various types of ships, including commercial ships, fishing boats, yachts, etc. Its main function is to raise and lower the anchor and retract the anchor chain to ensure the stability and safety of the ship when it is moored. Figure 1 As shown, the marine anchor winch drum protective cover is first processed into a semi-finished product through a bending process, and at this time, one side of the drum protective cover needs to be welded and sealed with the other side by a welding machine.

By setting the auxiliary component, the connecting rod can be moved to engage with the frame rod without manual operation, and the connection between the two ends of the connecting rod and the frame rod can also be automatically welded. 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 needs. Through the mutual cooperation of the auxiliary component and the positioning component, the connection between the frame rod and the connecting rod of the container frame can be realized at one time without the need for secondary components, which greatly improves the welding quality and stability of the container frame.

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 center tube 43.

[0038] See also Fig.16 Furthermore, a plurality of limiting holes 34 are provided on the surface of the L-shaped frame 31 , and a limiting groove 431 is provided on the inner wall of the central tube 43 .

[0039] See also Fig.12 and Fig.16 Further, the second transmission assembly 42 includes a first transmission gear 421, a first synchronous wheel 422, a synchronous belt 423 and a second synchronous wheel 424, the first transmission gear 421 and the first synchronous wheel 422 are coaxially connected to the surface of the arc-shaped side plate 22, the second synchronous wheel 424 is fixedly connected to the center tube 43, the synchronous belt 423 is connected between the first synchronous wheel 422 and the second synchronous wheel 424, and the driving gear 121 is transmission-connected to the first transmission gear 421.

[0040] In the embodiment of the present invention, when the electromagnet 24 is fitted with the magnetic sheet 128, the driving gear 121 is connected to the tooth groove 33, the first limiting rod 125 is disengaged from the limiting hole 34, and 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 the surface of the limiting frame 25, the driving gear 121 is connected to the first transmission gear 421, the first limiting rod 125 enters the limiting hole 34, and the limiting rib 127 is disengaged from the limiting groove 431. During this process, the first limiting rod 125 always passes through the surface of the limiting frame 25.

[0041] Working principle: Refer to the attached Fig.13, firstly, place the cover body 7 on the surface of the material discharging 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, and 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, the electromagnet 24 is controlled to be powered off. Since the electromagnet 24 loses the magnetic attraction to the magnetic sheet 128 after power failure, the first return spring 28 drives the first L-shaped plate 124 to fit the surface of the limiting rack 25. At this time, the driving gear 121 is connected to the second transmission assembly 42 in transmission, and the first limiting rod 125 enters the limiting hole 34 to limit the welding mechanism longitudinally, and the limiting rib 127 is separated from the limiting groove 431; Reference Fig.14 Then, the driving motor 111 is controlled to drive the driving gear 121 to rotate by driving the square rod 112. The rotating driving gear 121 controls the material rack 41, the clamping assembly 5 and the flattening assembly 6 to rotate 90 degrees toward the direction close to the welding head module 32 with the center tube 43 as the axis through the first transmission gear 421. In this process, the second transmission gear 62 in the flattening assembly 6 achieves the purpose of controlling the rotation of the threaded tube 61 by means of transmission connection with the arc-shaped rack 27. The rotating threaded tube 61 drives the pressing plate 64 to move through the threaded rod 63, and the moving pressing plate 64 can squeeze the cover body 7. On one side of the edge to be welded, the cover body 7 can be ensured to fit with the support plate 47 on the one hand, and on the other hand, the side of the edge to be welded of the cover body 7 can be ensured to fit with the other side of the second L-shaped plate 44, so that the cover body 7 can be ensured to be in a pre-closed state, which is convenient for the next welding operation. When the conical block 52 in the clamping assembly 5 and the trapezoidal platform 26 are in sliding contact until they are stationary, the trapezoidal platform 26 can drive the conical block 52 to move along the axis of the slide bar 53, thereby driving the clamping plate 51 to squeeze the cover body 7 toward the second L-shaped plate 4, so as to ensure that the side of the edge to be welded of the cover body 7 is aligned with the other side edges; Continue to refer to the attached Fig.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; Reference Fig.15After 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.

[0042] 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.
