Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a welding and repair device for tire mold repair includes a workbench 1, a lifting column 2 fixedly installed on the workbench 1, an electric gripper 3 for clamping the tire mold on one side of the lifting column 2, and a placement groove 4 corresponding to the electric gripper 3 on the workbench 1.

[0025] A support base 7 is fixedly installed in the center of the placement groove 4. Multiple sets of connecting rods 8 are evenly distributed on the outside of the support base 7. A frame 9 is fixedly installed at one end of the connecting rod 8. A sliding groove 10 is opened inside the frame 9. Multiple sets of bearing seats 12 are slidably installed inside the sliding groove 10. Welding heads 5 are installed on the bearing seats 12.

[0026] The bottom of the slide 10 is provided with a drive assembly 6, which is used to drive multiple sets of welding heads 5 to move inside the frame 9.

[0027] In this embodiment, when welding repairs are performed inside the tire mold, the tire mold to be repaired is clamped by the electric gripper 3. First, the lifting column 2 is used to move the tire mold upward to determine the welding repair position inside the tire mold. According to the position to be welded on the tire mold, the position of the welding head 5 is adjusted by the drive component. When the welding repair area is large, the welding head 5 is concentrated for welding. If the welding repair area is large and scattered, the distance between the welding heads 5 on the top of the bearing seat 12 is increased. Finally, the lifting column 2 is moved downward until the tire mold is completely covered, and the welding head 5 is used for welding repair. This method can repair multiple worn positions inside the tire mold at one time, resulting in high welding repair efficiency.

[0028] As one implementation method, such as Figure 1 , Figure 2 and Figure 4 As shown, the drive assembly 6 includes a support rod 13 movably mounted on the bottom of multiple sets of bearing seats 12. The support rods 13 are arranged in a mirror symmetrical manner. Each set of support rods 13 has a meshing tooth 14 fixedly installed on one side of its top end. The meshing teeth 14 of adjacent sets of two sets of meshing teeth mesh with each other, and the adjacent support rods 13 of the multiple sets of bearing seats 12 are hinged to each other.

[0029] One end of the unhinged support rod 13 is movably connected to a guide rod 18, and one end of the guide rod 18 is movably installed at the bottom end of the arc-shaped block 19. The arc-shaped block 19 is slidably installed in the slide groove 10. One end of another set of unhinged support rods 13 is movably connected to a traction rod 11, and one end of the traction rod 11 is movably installed at the bottom end of the frame 9.

[0030] In this embodiment, when the arc-shaped block 19 moves, the traction rod 11 at the bottom of the arc-shaped block 19 pulls the support rod 13, and the adjacent support rods 13 are gradually pulled apart at the bottom of the bearing seat 12, so that the bearing seat 12 moves within the frame 9 until the support rods 13 reach the maximum distance. Under the action of the meshing teeth 14, the position of the bearing seat 12 within the frame 9 is restricted, and the position of the welding head 5 within the frame 9 is adjusted, which facilitates the repair of multiple welding repair positions.

[0031] As one implementation method, such as Figure 1 , Figure 2 and Figure 4 As shown, a servo motor 15 is installed inside the support base 7. A rotating head 16 is fixedly installed at the output end of the servo motor 15. The rotating head 16 is rotatably installed at the top of the support base 7, and a connecting rod 17 is fixedly installed on the outside of the rotating head 16. One end of the connecting rod 17 is movably installed at the top of the arc-shaped block 19.

[0032] In this embodiment, the servo motor 15 drives the rotating head 16 to rotate. The connecting rod 17 on one side of the rotating head 16 drives the arc block 19 to move in the slide groove 9 within the frame 9. When the arc block 19 moves, the traction rod 11 at the bottom of the arc block 19 pulls the support rod 13. The adjacent support rods 13 are gradually pulled apart at the bottom of the bearing seat 12, so that the bearing seat 12 moves within the frame 9, thereby adjusting the position of the welding head 5 within the frame 9. The rotation is controlled by the servo motor 15.

[0033] As one implementation method, such as Figure 2 As shown, at least five sets of bearing seats 12 are provided, and the bearing seats 12 and the arc-shaped blocks 19 are components of the same size.

[0034] In this embodiment, the arc-shaped block 19 moves and, in cooperation with the support rod 13, pulls the bearing seat 12 to move in the slide groove 10 of the frame 9. At the same time, the cooperation of the five sets of bearing seats 12 with the welding head 5 facilitates the simultaneous repair of multiple welding positions.

[0035] As one implementation method, such as Figure 2 , Figure 4 As shown, the rotating head 16 and the connecting rod 17 are integrally formed structures. The length of the connecting rod 17 is greater than the length of the support rod 13. The traction rod 11, the guide rod 18 and the support rod 13 are the same length.

[0036] In this embodiment, the rotating head 16 and the connecting rod 17 drive the arc block 19 to move, thereby adjusting the position of multiple welding heads 5. When the guide rod 18 rotates to its end, the guide rod 18 and the traction rod 11 gradually approach each other.

[0037] As one implementation method, such as Figure 1 , Figure 2 As shown, frame 9 is a circular structure, and the diameter of frame 9 is smaller than the diameter of placement slot 4.

[0038] In this embodiment, the tire mold that needs to be repaired is clamped by the electric gripper 3. First, the lifting column 2 is used to move the tire mold upward. After determining the position of the welding head 5, the lifting column 2 is used to move it downward until the tire mold completely covers the frame 9. Then, the welding head 5 is used to perform the welding repair operation.

[0039] Working principle: During use, when welding repairs are performed inside the tire mold, the tire mold to be repaired is clamped by the electric gripper 3. First, the lifting column 2 moves the tire mold upward to determine the welding repair position inside the tire mold. Then, the servo motor 15 drives the rotating head 16 to rotate. The connecting rod 17 on one side of the rotating head 16 drives the arc block 19 to move in the sliding groove 9 within the frame 9. When the arc block 19 moves, the traction rod 11 at the bottom of the arc block 19 pulls the support rod 13. The adjacent support rods 13 are gradually pulled apart at the bottom of the bearing seat 12, so that the bearing seat 12 is in the frame 9. The support rods 13 move inward until the maximum spacing between them is reached. Under the action of the meshing teeth 14, the position of the bearing seat 12 within the frame 9 is restricted. Thus, the position of the welding head 5 can be adjusted according to the location where the tire mold needs to be welded. When the welding area is large, the spacing between the support rods 13 is reduced so that the welding head 5 is concentrated for welding. If the welding area is large and scattered, the spacing between the welding heads 5 at the top of the bearing seat 12 is increased by pulling apart the adjacent support rods 13. Finally, the lifting column 2 moves downward until the tire mold is completely covered, and then the welding head 5 is used for welding.
