[0024] 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.
[0025] like Figures 1 to 5 As shown, this utility model provides a welding device for a marine tow hook assembly, including a positioning component for positioning the tow hook mounting plate 1 and the tow hook body 2, a clamping component for applying pressure to the tow hook body 2 to fix it on the tow hook mounting plate 1, and a welding execution component for welding. The positioning component is located below the clamping component.
[0026] Specifically, such as Figures 1 to 4 As shown, the positioning component is mounted on the first mounting plate 19, and the clamping component is mounted on the second mounting plate 17. The first mounting plate 19 and the second mounting plate 17 are horizontally arranged, with the first mounting plate 19 located below the second mounting plate 17. The positioning component 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 embedded in. The positioning base plate 3 is fixedly mounted on the first mounting plate 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.
[0027] like Figures 1 to 4As shown, the clamping assembly includes a clamping support 7, a first driver 8 connected to the clamping support 7 and used to control the lifting and lowering of the clamping support 7, and a first clamping block 9 disposed on the clamping support 7. The first driver 8 is a cylinder fixedly disposed on the second mounting plate 17. The first driver 8 is vertically disposed, and the clamping device is fixedly connected to the lower end of the piston rod of the first driver 8. The first clamping block 9 is vertically disposed, and the upper end of the first clamping block 9 is fixedly connected to the clamping support 7. The lower end of the 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.
[0028] like Figures 1 to 4 As shown, the clamping assembly also includes a second clamping block 10 arranged side-by-side with the first clamping block 9. The second clamping block 10 is connected to the 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 clamping support 7, and the lower end of the buffer rod is slidably connected to the upper end of the second clamping block 10. The buffer spring is sandwiched between the top surface of the second clamping block 10 and the clamping support 7. The buffer spring is a cylindrical helical spring and a compression spring. The buffer spring applies an elastic force to the second clamping block 10, causing it to move downward. The lower end of the 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. The first clamping block 9 and the second clamping 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 is used to accommodate workpiece dimensional errors (the two lower ends of the tow hook body 2 may have dimensional deviations during processing), ensuring uniform clamping. The elastic deformation capability of the spring allows the second clamping block 10 to adaptively adjust its position in the vertical direction. 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 clamping block 9 and the second clamping 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.
[0029] like Figures 1 to 4 As shown, in this embodiment, three positioning pins 4 and three spring buffer rods 11 are provided.
[0030] like Figures 1 to 4 As shown, the welding execution assembly is located outside the positioning assembly. The welding execution assembly includes a welding torch body 12, a welding frame 13, a first sliding seat 14, a second driver 15 connected to the first sliding seat 14 and used to control the lifting and lowering of the first sliding seat 14, and a welding torch holder 16 disposed on the first sliding seat 14. The welding torch body 12 is disposed on the welding torch holder 16, and the second driver 15 is disposed on the welding frame 13. The welding frame 13 is vertically oriented, and a guide rail 18 is disposed on the welding frame 13. 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 second driver 15 is a cylinder fixedly disposed on the welding frame 13, and is vertically oriented. The lower end of the piston rod of the first sliding seat 14 and the second driver 15 are fixedly connected. The welding torch body 12 is used to weld the hook mounting plate 1 and the hook body 2. The second driver 15 controls the first sliding seat 14 to move in the vertical direction to adjust the height of the welding torch body 12.
[0031] like Figure 1 and Figure 6 As 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, with the base acting as a guide for the second sliding 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.
[0032] The first mounting plate 19 and the second mounting plate 17 are fixedly mounted on the rotating platform. The axis of the rotating platform is a vertical line. The rotating platform is connected to the second drive mechanism. The second drive mechanism controls the rotating platform to rotate. The rotating platform drives the first mounting plate 19, the second mounting plate 17, the positioning component and the clamping component to rotate synchronously, so as to adjust the angle between the hook mounting plate 1 and the hook body 2 to match the welding position of the welding gun. The second drive mechanism mainly includes a second drive motor, which is connected to the rotating platform at the center of the rotating platform.
