[0030] Reference Figures 1 to 6 This utility model provides a six-axis welding robot for preventing slag spatter: it includes a base 1 and a robot body 2. The robot body 2 is rotatably connected to the upper surface of the base 1 via a drive motor. An installation block 3 is rotatably connected to the end of the robot body 2 away from the base 1. A welding device body 4 is provided on the side wall of the installation block 3 away from the robot body 2. A welding torch 5 is fixedly installed at the bottom end of the welding device body 4. A welding head 6 is inserted into the bottom end of the welding torch 5. A top plate 7 is fixedly installed on the outer surface of the welding torch 5. An installation cylinder 8 is sleeved on the outer surface of the welding torch 5. A sliding cylinder 9 is sleeved on the outer surface of the installation cylinder 8. A protective cover 10 is fixedly installed at the bottom end of the sliding cylinder 9. The welding head 6 is located inside the protective cover 10. A slider 11 is fixedly installed on the outer surface of the welding torch 5. A sliding groove adapted to the slider 11 is opened on the inner wall of the installation cylinder 8. A fixing bolt 12 is threadedly connected to the outer surface of the installation cylinder 8. The fixing bolt 12 passes through the outer surface of the installation cylinder 8 and is inserted into the outer surface of the welding torch 5.

[0031] To facilitate the movement and repositioning of the protective cover 10, two fixing blocks 13 are fixedly installed on the outer surface of the mounting cylinder 8 near the top and the outer surface of the bottom. Two connecting brackets 14 are fixedly installed on the outer surface of the sliding cylinder 9. The two fixing blocks 13 at the bottom of the mounting cylinder 8 are set inside the corresponding connecting brackets 14. A sliding rod 15 is fixedly connected between the two fixing blocks 13 on the same side. The sliding rod 15 passes through the inner wall of the connecting bracket 14. A spring 16 is sleeved on the outer surface of the sliding rod 15. One end of the spring 16 is fixedly connected to the fixing block 13 at the top of the mounting cylinder 8, and the other end of the spring 16 is fixedly connected to the outer surface of the connecting bracket 14.

[0032] By setting up a base 1, robot body 2, mounting block 3, welding device body 4, welding torch 5, welding head 6, top plate 7, mounting cylinder 8, sliding cylinder 9, protective cover 10, slider 11, fixing bolt 12, fixing block 13, connecting frame 14, sliding rod 15, and spring 16, the function of preventing welding slag from splashing is realized. By setting a retractable protective cover 10 on the outside of the welding head 6, the protective cover 10 blocks the welding slag during the welding process, preventing the welding slag from splashing everywhere, thus making the cleaning of welding slag more convenient and improving the practicality of the welding robot.

[0033] The outer surface of the welding device body 4 is provided with an installation component, which includes a fixed sleeve 17 and a rotating sleeve 18. The fixed sleeve 17 is fixedly installed on the side wall of the mounting block 3 away from the robot body 2. The rotating sleeve 18 is sleeved on the outer surface of the welding device body 4. The outer surface of the fixed sleeve 17 has an external thread, and the inner wall of the rotating sleeve 18 has an internal thread that meshes with the external thread. A positioning ring 19 is fixedly installed on the inner wall of the bottom end of the rotating sleeve 18. A positioning seat 20 is fixedly installed on the outer surface of the welding device body 4. The positioning ring 19 is located inside the positioning seat 20. A limit block 21 is fixedly installed on the inner wall of the fixed sleeve 17. A limit groove that matches the limit block 21 is opened on the outer surface of the welding device body 4. An installation bolt 22 is threadedly connected to the outer surface of the fixed sleeve 17. The installation bolt 22 penetrates the outer surface of the fixed sleeve 17 and is inserted into the outer surface of the welding device body 4.

[0034] By setting up a fixed sleeve 17, a rotating sleeve 18, a positioning ring 19, a positioning seat 20, a limiting block 21, and mounting bolts 22, the function of quickly and conveniently installing and disassembling the welding device as a whole is realized. This improves the connection method between the welding device and the robot body 2 in the existing technology, so that when the welding device needs to be repaired or replaced, it can be quickly disassembled and assembled, saving time and effort. On the basis of the original, the practicality of the welding device is further improved.

[0035] Working principle: Before using the welding robot for welding work, the protective cover 10 is installed first. The protective cover 10 is moved close to the welding device so that the welding torch 5 and welding head 6 are aligned with the mounting cylinder 8. The protective cover 10 is moved so that the mounting cylinder 8 is fitted onto the outer surface of the welding torch 5. The mounting cylinder 8 slides on the outer surface of the welding torch 5, and the slider 11 slides inside the groove. When the mounting cylinder 8 contacts the top plate 7, the protective cover 10 is connected to the welding robot. Then the fixing bolt 12 is turned. When the fixing bolt 12 passes through the outer surface of the mounting cylinder 8 and turns into the outer surface of the welding torch 5, the mounting cylinder 8 is fixed, thus completing the installation of the protective cover 10.

[0036] When using a welding robot for welding work, the joints of the robot body 2 rotate, causing the mounting block 3 to drive the welding device body 4 to move toward the workpiece to be welded. The welding head 6 approaches the workpiece. When the protective cover 10 contacts the workpiece, the workpiece squeezes the protective cover 10, causing the protective cover 10 to drive the slide cylinder 9 to slide on the outer surface of the mounting cylinder 8. The fixing block 13 at the bottom of the mounting cylinder 8 slides inside the connecting frame 14. The connecting frame 14 slides on the outer surface of the slide rod 15. The spring 16 is compressed and deformed, causing the welding head 6 to extend out from inside the protective cover 10. When the welding head 6 contacts the workpiece, it welds the workpiece. During the welding process, the protective cover 10 blocks the splashing welding slag, preventing the welding slag from splashing over a large area.

[0037] When the welding device is damaged and needs repair or replacement, first loosen the mounting bolt 22 to extend it away from the fixed sleeve 17. After the mounting bolt 22 separates from the welding device body 4, the restriction on the welding device body 4 is released. Then rotate the rotating sleeve 18 so that it rotates on the outer surface of the fixed sleeve 17 through the positioning ring 19 and the positioning seat 20. At the same time, with the cooperation of the internal and external threads, the rotating sleeve 18 drives the welding device body 4 away from the fixed sleeve 17, so that the welding device body 4 slides inside the fixed sleeve 17 and the limiting block 21 slides inside the limiting groove. When the welding device body 4 slides out from inside the fixed sleeve 17, the disassembly of the welding device is completed. At this time, the welding device can be repaired or replaced. After the welding device is repaired or replaced, the above operation is reversed to reinstall the welding device onto the robot body 2.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
