Description

Technical Field

[0001] This utility model relates to the field of welding robot technology for wheel production, and in particular to a welding robot for wheel production. Background Technology

[0002] With the development of electronic technology, computer technology, numerical control and robotics technology, automatic welding robots have been used in production since the 1960s. Their technology has become increasingly mature, and they have advantages such as improving labor productivity, reducing the labor intensity of workers, and shortening the preparation cycle for product modification and replacement. For the welding work that needs to be done in the production of automobile wheels, welding robots are usually used to improve and stabilize welding quality and increase production efficiency.

[0003] For example, patent number 202220918118.2 discloses a welding robot arm for automobile production. Its structure includes a body, with a connecting arm at the upper end of the body. A welding torch is connected to the end of the connecting arm, and a mounting sleeve is rotatably connected to the end of the connecting arm via a bearing. Symmetrically distributed longitudinal grooves are provided on the outer side of the mounting sleeve, and a first spring is fixedly connected inside the grooves. A protective cover is movably fitted outside the mounting sleeve, and the welding torch is located inside the protective cover. An observation port is provided on the outer side of the protective cover, and symmetrically distributed sliders are fixedly connected inside the protective cover. The sliders slide within the longitudinal grooves, and the other end of the first spring is fixedly connected to the sliders. This invention, through the protective cover located outside the welding torch, and adjustable according to usage requirements, blocks most of the high-intensity light and welding sparks, preventing injury to operators from strong light and welding sparks, improving the welding working environment. The observation port facilitates worker inspection of the welding torch and absorption of welding fumes.

[0004] Therefore, while installing a protective cover on the outside of the welding robot solves the problems of fume absorption and preventing welding sparks from splashing, prolonged use of the welding robot will cause wear on the welding head, which will affect subsequent welding efficiency. However, the existing welding head and robot are an integrated structure, making subsequent disassembly and installation of the welding head relatively complicated, thus reducing work efficiency and increasing the working time of personnel. To address this issue, a structure that allows for quick disassembly and installation of the welding head can be designed, saving time and effort and improving subsequent work efficiency.

[0024] Please see Figure 1 In this embodiment, a support table 1 is provided below the welding robot body 4. Support feet are fixedly provided on the four ends of the lower surface of the support table 1, and anti-slip pads are provided on the surface of the support feet. Guide rails 2 are provided on both the left and right sides of the upper surface of the support table 1. Sliding guide blocks 3 are slidably sleeved on the outside of the two guide rails 2. The welding robot body 4 is provided above the sliding guide blocks 3. A snap-fit ​​groove is opened inside one side of the welding robot body 4, and the movable arm 5 snaps into the snap-fit ​​groove. The movable arm 5 and the welding robot body 4 are movably connected through each other. With a movable shaft, when disassembling the welding head 8, first pull the insert rod 16 to one side to disengage it from the slot 15. Then, by moving the toggle block 19, it slides to one end, simultaneously causing the L-shaped insert block 20 located inside the movable groove 21 to also begin to move into the movable groove 21, so that the L-shaped insert block 20 disengages from the fixed groove 14. Finally, slowly rotate the mounting head 7 so that the threaded block 12 at one end engages inside the threaded groove 9 and slowly disengages from the threaded groove 9, thus completing the disassembly of the welding head 8.

[0025] Please see Figures 3-5In this embodiment, one end of the threaded groove 9 is provided with a mounting groove 10 located inside the mounting base 6. The mounting head 7 is inserted into the mounting groove 10. Each of the four end feet on the inner wall of the mounting groove 10 is fixedly provided with a positioning protrusion 11. Each of the four end feet on the surface of the mounting head 7 is provided with a positioning groove 13. The four positioning protrusions 11 are inserted into the four positioning grooves 13. One end of each of the four positioning grooves 13 is provided with a rotating groove located inside the mounting head 7. The positioning protrusions 11 rotate within the rotating groove. During installation, the threaded block 12 at one end of the mounting head 7 is first aligned with... The threaded groove 9 inside the mounting base 6 rotates and engages, while the positioning protrusion 11 inside the mounting base 6 aligns with the positioning grooves 13 on the four ends of the mounting head 7 and engages. Finally, the lever 19 is moved so that the L-shaped insert 20 on one side is slowly inserted into the fixing groove 14 inside the mounting base 6 and fixed.

[0026] During operation, when disassembling the welding head 8, first pull the insert rod 16 to one side to disengage it from the slot 15. Then, by moving the lever 19, it slides to one end, simultaneously causing the L-shaped insert 20 located inside the movable slot 21 to move into the movable slot 21, thus disengaging the L-shaped insert 20 from the fixed slot 14. Finally, slowly rotate the mounting head 7 so that the threaded block 12 at one end engages inside the threaded groove 9 and slowly disengages from the threaded groove 9, completing the disassembly of the welding head 8. During installation, first... The threaded block 12 at one end of the mounting head 7 is aligned with the threaded groove 9 inside the mounting base 6 and rotated to engage and engage. At the same time, the positioning protrusion 11 inside the mounting base 6 is aligned with the positioning grooves 13 opened on the four ends of the mounting head 7 and engages. Finally, the lever 19 is moved so that the L-shaped insert 20 on one side is slowly inserted into the fixing groove 14 inside the mounting base 6 and fixed. The pulled insert rod 16 is released so that it is inserted into the slot 15 for reinforcement and fixation. The installation of the welding head 8 is completed. This disassembly and assembly method is simpler and more convenient than the previous disassembly and assembly structure, improves the efficiency of disassembly and assembly, and saves time and effort.

[0027] Through the above steps, when disassembling the welding head 8, first pull the insertion rod 16 to one side to disengage it from the slot 15. Then, by moving the toggle block 19, it slides to one end, simultaneously causing the L-shaped insertion block 20 located inside the movable slot 21 to also move into the movable slot 21, so that the L-shaped insertion block 20 disengages from the fixed slot 14. Finally, slowly rotate the mounting head 7 so that the threaded block 12 at one end engages inside the threaded groove 9 and slowly moves away from the threaded groove 9. Finally, the disassembly of the welding head 8 can be completed. This solves the problem of absorbing fumes and preventing welding sparks from splashing when installing a protective cover on the outside of the welding robot. However, long-term use of the welding robot will cause wear on the welding head, which will affect the subsequent welding efficiency. However, the existing welding head and robot are an integrated structure, and the subsequent disassembly and installation of the welding head is relatively complicated, thereby reducing work efficiency, increasing the working time of personnel, and causing time and labor costs.
