[0041] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0042] like Figures 1 to 13 As shown, this utility model provides a welding equipment for a marine tow hook assembly, including a fixed base, a fixed plate, a positioning component for positioning the tow hook mounting plate and the tow hook body, a rotary table rotatably configured to drive the positioning component to switch between a loading station, an inspection station, a first-stage welding station, a second-stage welding station, a third-stage welding station, a fourth-stage welding station, and a unloading station, a first-stage clamping component for applying pressure to the tow hook body at the first-stage welding station, and a second-stage clamping component for applying pressure to the tow hook body at the second-stage welding station. The system includes a two-stage pressure clamping assembly, a three-stage pressure clamping assembly for applying pressure to the tow hook body at the three-stage welding station, a four-stage pressure clamping assembly for applying pressure to the tow hook body at the four-stage welding station, a welding execution assembly for welding the tow hook body and the tow hook mounting plate, and a material unloading device located at the unloading station. Multiple positioning assemblies are provided on the rotary table. Welding execution assemblies are provided at the first-stage welding station, the second-stage welding station, the third-stage welding station, and the fourth-stage welding station. The fixing plate is fixedly installed on the fixing base.

[0043] Specifically, such as Figure 1 and Figure 2As shown, the rotary table 19 is horizontally positioned with its axis vertical. The rotary table 19 is located above a fixed frame, on which a main drive mechanism for controlling the rotation of the rotary table 19 is mounted. This main drive mechanism primarily includes a drive motor and is connected to the rotary table 19 at its center. Multiple positioning components are located on the top surface of the rotary table 19, evenly distributed circumferentially around its axis. The loading station, inspection station, first-stage welding station, second-stage welding station, third-stage welding station, fourth-stage welding station, and unloading station are sequentially distributed circumferentially. Inspection components, first-stage clamping components, second-stage clamping components, third-stage clamping components, fourth-stage clamping components, and the unloading device are distributed around the outer perimeter of the rotary table 19. The detection component is located at the detection station. The first-stage clamping component and one welding execution component are located at the first-stage welding station. The second-stage clamping component and one welding execution component are located at the second-stage welding station. The third-stage clamping component and one welding execution component are located at the third-stage welding station. The fourth-stage clamping component and one welding execution component are located at the fourth-stage welding station. The unloading device is located at the unloading station. The welding execution components located at each welding station have the same structure.

[0044] like Figures 4 to 7 As shown, the positioning assembly is mounted on a rotating platform 19. The rotating platform 19 and the fixed plate 17 are horizontally positioned, with the rotating platform 19 located below the fixed plate 17. The positioning assembly includes a positioning base plate 3, positioning pins 4 mounted on the positioning base plate 3 for positioning the tow hook mounting plate 1, and positioning blocks 5 mounted on the positioning base plate 3 for positioning the tow hook body 2. The positioning blocks 5 have positioning grooves 6 for the tow hook body 2 to be inserted into. The positioning base plate 3 is fixedly mounted on the rotating platform 19, and the positioning pins 4 are vertically mounted on the positioning base plate 3. Multiple positioning pins 4 are provided, all located on the same side of the positioning blocks 5. The positioning base plate 3 supports the tow hook mounting plate 1. The bottom surface of the tow hook mounting plate 1 has positioning holes for the positioning pins 4 to be inserted. All positioning holes are located at the same end of the tow hook mounting plate 1. By using multiple positioning pins 4 at the same end of the tow hook mounting plate 1, the tow hook mounting plate 1 is positioned, ensuring the accurate position of the tow hook mounting plate 1. The positioning block 5 is fixedly set on the top surface of the positioning base plate 3. The shape of the positioning groove 6 matches the shape of the tow hook body 2. A part of the tow hook body 2 is embedded in the positioning groove 6 to achieve positioning. The lower end of the tow hook body 2 is located on the top surface of the tow hook mounting plate 1. The contact part between the lower end of the tow hook body 2 and the top surface of the tow hook mounting plate 1 is the part that needs to be welded.

[0045] like Figure 1 and Figure 2 As shown, at the loading station, the hook mounting plate 1 and the hook body 2 are placed on the positioning component manually to achieve manual loading.

[0046] like Figure 12 As shown, at the inspection station, the inspection component is used to detect whether there is a workpiece on the positioning component at the inspection station, that is, to determine whether the positioning component carrying the hook body 2 and the hook mounting plate 1 has moved into place. The inspection component includes an upper support 27, a lower support 28, an inspection driver 26 connected to the lower support 28 and used to control the lifting and lowering of the lower support 28, and a first inspection element 29 and a second inspection element 30 disposed on the lower support 28. The inspection driver 26 is a cylinder fixedly disposed on the upper bracket 24. One end of the upper bracket 24 is fixedly connected to the upper end of the lower bracket 25, and the lower end of the lower bracket 25 is fixedly connected to the fixed base. The upper bracket 24 is horizontally disposed, and the fixed plate 17 is fixedly disposed on the upper bracket 24. Multiple upper brackets 24 and lower brackets 25 are provided, and the rotary table 19 is located below the fixed plate 17. The detection driver 26 is vertically positioned, with the lower support 28 and upper support 27 fixedly connected. The upper support 27 is fixedly connected to the lower end of the piston rod of the detection driver 26. The first detection element 29 and the second detection element 30 are vertically positioned, aligned with the two lower ends of the hook body 2, forming a "two-point" detection layout. The two elements can simultaneously verify the positional accuracy and integrity of the workpiece. Only when signals are detected at both points is it confirmed that the workpiece is correctly installed and the positioning assembly has moved into place. The first detection element 29 and the second detection element 30 can be photoelectric sensors or proximity switches, with short response time and high detection accuracy, ensuring that subsequent processes are triggered immediately after the positioning assembly rotates into place.

[0047] At the first welding station, a first-order clamping assembly is used to apply pressure to the tow hook body 2 to fix it to the tow hook mounting plate 1. The first-order clamping assembly is disposed on the fixing plate 17, such as... Figures 4 to 7 As shown, the sequential clamping assembly includes a sequential clamping support 7, a first driver 8 connected to the sequential clamping support 7 and used to control the lifting and lowering of the sequential clamping support 7, and a sequential first clamping block 9 disposed on the sequential clamping support 7. The first driver 8 is a cylinder fixedly disposed on the fixed plate 17 and is vertically disposed. The lower end of the piston rod of the sequential clamping support 7 is fixedly connected to the piston rod of the first driver 8. The sequential first clamping block 9 is vertically disposed. The upper end of the sequential first clamping block 9 is fixedly connected to the sequential clamping support 7, and the lower end of the sequential first clamping block 9 is used to contact the lower end of the tow hook body 2 to apply pressure to the tow hook body 2 to fix it on the tow hook mounting plate 1.

[0048] like Figures 4 to 7As shown, the sequential clamping assembly also includes a sequential second clamping block 10 arranged side-by-side with the sequential first clamping block 9. The sequential second clamping block 10 is connected to the sequential clamping support 7 via spring buffer rods 11. Multiple spring buffer rods 11 are provided, and the spring buffer rods 11 are vertically arranged. The spring buffer rod 11 mainly includes a buffer rod and a buffer spring. The buffer spring is sleeved on the buffer rod, which is vertically arranged. The upper end of the buffer rod is connected to the sequential clamping support 7, and the lower end of the buffer rod is slidably connected to the upper end of the sequential second clamping block 10. The buffer spring is sandwiched between the top surface of the sequential second clamping block 10 and the sequential clamping support 7. The buffer spring is a cylindrical helical spring and a compression spring. The buffer spring applies an elastic force to the sequential second clamping block 10, causing it to move downward. The lower end of the sequential second clamping block 10 is used to contact the lower end of the tow hook body 2, applying pressure to the tow hook body 2 to fix it on the tow hook mounting plate 1. The tow hook body 2 is roughly U-shaped, with two lower ends that are rod-shaped. A first pressing block 9 and a second pressing block 10 contact the two lower ends of the tow hook body 2, fixing them to the tow hook mounting plate 1. A spring-loaded buffer rod 11 accommodates workpiece dimensional errors (the two lower ends of the tow hook body 2 may have dimensional deviations during processing), ensuring uniform clamping. The spring's elastic deformation allows the second pressing block 10 to adaptively adjust its position vertically. When the two lower ends of the tow hook body 2 are at different heights, the spring compression automatically changes with the actual height, ensuring that both the first pressing block 9 and the second pressing block 10 are in close contact with their corresponding lower ends. This avoids insufficient or excessive clamping force at one end due to rigid connection, thus ensuring accurate workpiece positioning and uniform clamping before welding. As an elastic element, the spring can adjust the actual clamping force through its own compression. When the pressure exceeds the preset threshold, the spring is further compressed without increasing the rigid impact force, thereby preventing the workpiece from deforming due to overload, while ensuring sufficient clamping force required for welding.

[0049] like Figures 4 to 7 As shown, in this embodiment, three positioning pins 4 and three spring buffer rods 11 are provided.

[0050] In the first welding station, the tow hook mounting plate is initially welded to the tow hook body to form the first sub-assembly. Then, the first clamping block 9 and the second clamping block 10 separate from the first sub-assembly. The rotary table then rotates, causing the positioning components of the first welding station to move the first sub-assembly to the second welding station for further welding. Figure 9As shown, at the second-stage welding station, the second-stage clamping assembly applies pressure simultaneously to one lower end of the tow hook body 2 and the tow hook mounting plate 1. The second-stage clamping assembly is mounted on the fixed plate 17. The rotary table 19 and the fixed plate 17 are horizontally arranged, with the rotary table 19 located below the fixed plate 17. The second-stage clamping assembly includes a second-stage clamping support 42, a second driver 43 connected to the second-stage clamping support 42 and used to control the lifting and lowering of the second-stage clamping support 42, and a second-stage clamping block 44 mounted on the second-stage clamping support 42. The second actuator 43 is a cylinder fixedly mounted on the fixed plate 17. The second actuator 43 is vertically mounted. The second-order clamping support 42 is fixedly connected to the lower end of the piston rod of the second actuator 43. The second-order clamping block 44 is vertically mounted. The upper end of the second-order clamping block 44 is fixedly connected to the second-order clamping support 42. The lower end of the second-order clamping block 44 is used to contact one lower end of the tow hook body 2 and the tow hook mounting plate 1 simultaneously, applying pressure to the tow hook body 2 and the tow hook mounting plate 1, so that the first sub-assembly is fixed on the positioning component, preventing the first sub-assembly from moving during the welding process.

[0051] At the second-stage welding station, the hook mounting plate is welded to the hook body again to form the second sub-assembly. Afterward, the second-stage clamping block 44 separates from the second sub-assembly. Then, the rotary table rotates, causing the positioning component at the second-stage welding station to move the second sub-assembly to the third-stage welding station for further welding. Figure 10 As shown, at the three-stage welding station, the three-stage clamping assembly applies pressure simultaneously to one lower end of the tow hook body 2 and the tow hook mounting plate 1. The three-stage clamping assembly is mounted on the fixed plate 17. The rotary table 19 and the fixed plate 17 are horizontally arranged, with the rotary table 19 located below the fixed plate 17. The three-stage clamping assembly includes a three-stage clamping support 45, a third driver 46 connected to the three-stage clamping support 45 and used to control the lifting and lowering of the three-stage clamping support 45, and a three-stage clamping block 47 mounted on the three-stage clamping support 45. The third actuator 46 is a cylinder fixedly mounted on the fixed plate 17. The third actuator 46 is vertically mounted. The three-stage clamping support 45 is fixedly connected to the lower end of the piston rod of the third actuator 46. The three-stage clamping block 47 is vertically mounted. The upper end of the three-stage clamping block 47 is fixedly connected to the three-stage clamping support 45. The lower end of the three-stage clamping block 47 is used to contact one lower end of the tow hook body 2 and the tow hook mounting plate 1 simultaneously, applying pressure to the tow hook body 2 and the tow hook mounting plate 1, so that the second sub-assembly is fixed on the positioning assembly, preventing the second sub-assembly from moving during the welding process.

[0052] At the second welding station, the lower end of the tow hook body 2 pressed by the second clamping block 44 is different from the lower end of the tow hook body 2 pressed by the third clamping block 47 at the second welding station. That is, the second clamping block 44 and the third clamping block 47 press the two different lower ends of the tow hook body 2 respectively.

[0053] At the third-stage welding station, the hook mounting plate is welded to the hook body again to form the third sub-assembly. Afterward, the third-stage clamping block 47 separates from the third sub-assembly. Then, the rotary table rotates, causing the positioning component at the third-stage welding station to move the third sub-assembly to the fourth-stage welding station for further welding. Figure 11 As shown, at the fourth-order welding station, the fourth-order clamping assembly is used to simultaneously apply pressure to one lower end of the tow hook body 2 and the tow hook mounting plate 1. The fourth-order clamping assembly is mounted on the fixed plate 17. The fourth-order clamping assembly includes a fourth-order clamping support 48, a fourth driver 49 connected to the fourth-order clamping support 48 and used to control the lifting and lowering of the fourth-order clamping support 48, and a fourth-order clamping block 50 mounted on the fourth-order clamping support 48. The fourth actuator 49 is a cylinder fixedly mounted on the fixed plate 17. The fourth actuator 49 is vertically mounted. The fourth-order clamping support 48 is fixedly connected to the lower end of the piston rod of the fourth actuator 49. The fourth-order clamping block 50 is vertically mounted. The upper end of the fourth-order clamping block 50 is fixedly connected to the fourth-order clamping support 48. The lower end of the fourth-order clamping block 50 is used to contact one lower end of the tow hook body 2 and the tow hook mounting plate 1 simultaneously, applying pressure to the tow hook body 2 and the tow hook mounting plate 1, so that the third sub-assembly is fixed on the positioning assembly, preventing the third sub-assembly from moving during the welding process.

[0054] like Figures 4 to 8 As shown, the welding execution assembly is located outside the rotary table. The assembly includes a welding torch body 12, a welding frame 13, a first sliding seat 14, a first lifting actuator 15 connected to the first sliding seat 14 and used to control its lifting and lowering, and a welding torch holder 16 mounted on the first sliding seat 14. The welding torch body 12 is mounted on the welding torch holder 16, and the first lifting actuator 15 is mounted on the welding frame 13. The welding frame 13 is vertically oriented and has a guide rail 18. The first sliding seat 14 is slidably connected to the guide rail 18, which is vertically oriented and guides the first sliding seat 14. The welding torch holder 16 is fixedly connected to the first sliding seat 14. The first lifting actuator 15 is a cylinder fixedly mounted on the welding frame 13, vertically oriented, and the lower end of the piston rod of the first lifting actuator 15 is fixedly connected to the first sliding seat 14. The welding torch body 12 is used to weld the hook mounting plate 1 and the hook body 2. The first lifting actuator 15 controls the first sliding seat 14 to move in the vertical direction, thereby adjusting the height of the welding torch body 12.

[0055] like Figure 4 and Figure 8As shown, the welding execution assembly also includes a base and a first drive mechanism mounted on the base. The first drive mechanism is connected to the welding frame 13 and is used to adjust the position of the welding torch body 12 in the horizontal direction. The first drive mechanism mainly includes a first drive motor, a first transmission mechanism connected to the first drive motor, and a second sliding seat connected to the first transmission mechanism. The lower end of the welding frame 13 is fixedly connected to the second sliding seat, and the second sliding seat is slidably connected to the base. The base guides the second sliding seat, and the base is fixedly mounted on a fixed seat. In this embodiment, the first transmission mechanism is a screw-nut mechanism. The screw of the screw-nut mechanism is connected to the output end of the first drive motor, and the nut of the screw-nut mechanism is fixedly connected to the second sliding seat. When the first drive motor operates, it transmits power to the second sliding seat through the screw-nut mechanism, causing the second sliding seat, welding frame 13, welding torch body 12, and other components to move linearly synchronously.

[0056] At the fourth welding station, after welding is completed, the final marine hook assembly is formed. After the marine hook assembly is formed, the fourth clamping block 50 separates from the fourth sub-assembly. Then the rotary table rotates, causing the positioning component of the fourth welding station to move the marine hook assembly to the unloading station for unloading.

[0057] like Figure 13 As shown, the unloading device includes an end effector for picking up the marine hook assembly located on the positioning component, a lifting component connected to the end effector and controlling the lifting of the end effector, a translation component connected to the lifting component and controlling the horizontal movement of the lifting component, a guide component connected to the lifting component and inserted into the positioning hole of the marine hook assembly, and an unloading slide plate 41 for guiding the marine hook assembly to a designated position to release the end effector.

[0058] like Figure 13 As shown, the translation component is installed on the unloading frame 37, which is installed on the fixed base. After the rotary table 19 moves the positioning component and the welded shipping hook assembly on it to the unloading position, the end effector picks up the shipping hook assembly located on the positioning component. Then, with the cooperation of the lifting component and the translation component, the shipping hook assembly is moved above the unloading slide plate 41. Then the end effector releases the shipping hook assembly. The unloading slide plate 41 is set to tilt downwards. The unloading slide plate 41 guides the received shipping hook assembly to the designated position, completing the automatic unloading of the shipping hook assembly.

[0059] like Figure 13As shown, in this embodiment, the end effector includes a translational gripper 32, which includes two jaws that cooperate to clamp the marine hook assembly. The lifting assembly includes a first lifting actuator 33 and a support plate 34 connected to the first lifting actuator 33. The end effector and guide assembly are fixedly mounted on the support plate 34. The first lifting actuator 33 is a cylinder, and the support plate 34 is fixedly connected to the piston rod of the first lifting actuator 33. The extension and retraction of the first lifting actuator 33 drives the support plate 34 and the end effector and guide assembly on it to move up and down.

[0060] like Figure 13 As shown, in this embodiment, the translation component includes a translation actuator 35 and a connecting plate 36 connected to the translation actuator 35. The translation actuator 35 is mounted on the unloading frame 37, and the connecting plate 36 is connected to the lifting component. The translation actuator 35 is a cylinder and is fixedly mounted on the unloading frame 37. One end of the connecting plate 36 is fixedly connected to one end of the piston rod of the translation actuator 35, and the translation actuator 35 is horizontally positioned. The other end of the connecting plate 36 is fixedly connected to the first lifting actuator 33, and the first lifting actuator 33 is slidably connected to the unloading frame 37. The unloading frame 37 guides the first lifting actuator 33. Through the extension and retraction of the translation actuator 35, the lifting component is driven to move horizontally.

[0061] like Figure 13 As shown, in this embodiment, the guiding assembly includes a second lifting actuator 38, a lifting support 39 connected to the second lifting actuator 38, and a guide rod 40 connected to the lifting support 39 and used for insertion into the positioning hole of the marine hook assembly. Multiple guide rods 40 are provided, and the number of guide rods 40 is the same as the number of positioning holes in the marine hook assembly. When the lifting assembly controls the end effector and the guiding assembly to descend and pick up materials, the guide rods 40 need to be inserted downwards into the positioning holes of the marine hook assembly located on the positioning assembly. Each guide rod 40 is inserted into one positioning hole. After the end effector picks up the marine hook assembly, the guide rods 40 remain inserted in the positioning holes, playing a positioning and guiding role, preventing the marine hook assembly from sagging and swaying, and keeping the marine hook assembly in a stable posture.

[0062] In this embodiment, the second lifting actuator 38 is a cylinder, the lifting support 39 is fixedly connected to the piston rod of the second lifting actuator 38, and the upper end of the guide rod 40 is fixedly connected to the lifting support 39. Through the extension and retraction of the second lifting actuator 38, the lifting support 39 and the guide rod 40 on it are driven to move up and down synchronously, so that the guide rod 40 can be inserted into the positioning hole of the marine hook assembly and moved out of the positioning hole.

[0063] The marine hook assembly welding equipment employing the above-described structure achieves high efficiency, precision, and automation in the welding process through multi-station collaboration, precise positioning, and elastic clamping. The multi-station rotary layout forms a circular assembly line operation, significantly improving production efficiency. The equipment uses a rotary table with circumferentially arranged loading, inspection, four-stage welding, and unloading stations. Positioning components switch stations sequentially with the rotary table, achieving a continuous cycle of "loading-welding-unloading." Parallel operation at each station (e.g., while a positioning component is being welded in one stage, other components can be loaded or inspected simultaneously) shortens single-process waiting time and increases production capacity.

[0064] Furthermore, the welding process is broken down into four stages, with each welding station focusing on welding specific areas, avoiding heat concentration and stress deformation caused by welding in one go. This design ensures welding quality while improving cycle time efficiency through parallel processes.

[0065] In the first-stage clamping assembly, the second clamping block is connected via a spring-loaded buffer rod. When there is a dimensional deviation in height between the two ends of the hook body, the spring compression automatically adjusts to ensure uniform clamping force at both ends, avoiding workpiece deformation or insufficient clamping force caused by rigid clamping. The second to fourth-stage clamping blocks act directly on the contact surface between the hook body and the mounting plate, achieving constant pressure through cylinder drive to prevent workpiece displacement during welding. The welding torches at each welding station have the same structure, facilitating unified maintenance and program debugging, and reducing equipment maintenance costs.

[0066] In the feeding device, the feeding slide is tilted downwards, using gravity to guide the finished product into the designated position. The automated process eliminates the need for manual material handling, reducing labor intensity and avoiding bumps and damage caused by manual handling.

[0067] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
