[0002] Welding is a processing technology and connection method that uses heating, pressurization, or both, with or without welding materials, to cause atomic diffusion between two workpieces to form a metallurgical bond. Welding is widely used and can be used for both metals and non-metals. During the welding process, the workpiece and the solder melt to form a molten area. After the molten pool cools and solidifies, a connection between the materials is formed. During this process, pressure is usually required. There are many sources of energy for welding, including gas flame, arc, laser, electron beam, friction and ultrasound. Welding robots can realize automated welding, which greatly improves production efficiency. For manual welding, robots have fast speed and high stability, and can achieve continuous welding, saving production time and increasing output. Modern welding robots are usually equipped with data acquisition and analysis systems, which can collect data from the welding process in real time, and perform data analysis and monitoring. These data can be used to optimize the welding process, improve production efficiency and product quality.

[0003] A car is made up of many different parts, each of which plays a specific role to ensure the normal operation and performance of the car. In the production process of automobile parts, welding robots are generally required to perform precise welding on automobile parts. Although the existing welding robots can achieve continuous automatic welding, their flexibility is limited. When facing larger automobile parts, the arm length is short and the welding gun cannot reach them, which is not conducive to use.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-4 A welding manipulator for automatic welding of automobile parts comprises a frame 1 and a welding manipulator body 11, wherein a lifting and moving mechanism is arranged inside the frame 1;

[0029] The lifting and moving mechanism includes a lifting cylinder 2 fixedly installed on the inner side of the frame 1, the output shaft of the lifting cylinder 2 is fixedly connected to the mounting frame 3, the inner side of the mounting frame 3 is relatively fixedly connected with two sleeve rods 4, the middle part of the inner side of the mounting frame 3 is rotatably connected with a worm 5, the outer surface of the sleeve rod 4 is slidably connected with a movable sleeve 6, the bottom of the movable sleeve 6 is fixedly connected with a base plate 7, the top of the base plate 7 is fixedly installed with a forward and reverse motor 8, the output shaft of the forward and reverse motor 8 is fixedly connected with a worm block 9, and the top of the movable sleeve 6 is fixedly connected with a top plate 10. By setting the lifting and moving mechanism, the lifting cylinder 2 can drive the mounting frame 3 to move up and down, thereby adjusting the horizontal height of the welding robot body 11.

[0030] In addition, the forward and reverse motor 8 can drive the worm block 9 to rotate. When the worm block 9 rotates, since the worm block 9 and the worm 5 are in a meshing transmission state, the worm block 9 can move on the outer surface of the worm 5 through the teeth on its outer surface, thereby driving the welding robot body 11 to move laterally and adjust its position.

[0031] Furthermore, compared with existing welding robots, it is more flexible and less likely for the welding gun to be unable to reach larger automotive parts, making it easier to use.

[0032] Among them, the worm block 9 is meshed with the worm 5 for transmission, the welding robot body 11 is fixedly installed on the top of the top plate 10, the sleeve rod 4 is distributed on both sides of the worm 5, and the left and right sides of the inner wall of the frame 1 are provided with strip grooves 12, and the inner side of the strip groove 12 is fixedly connected with a limit rod 13 for improving stability, and the left and right sides of the mounting frame 3 are fixedly connected with a connecting plate 14, and the connecting plate 14 is sleeved with the limit rod 13. By setting the limit rod 13 and the connecting plate 14, the effect of limiting the position of the mounting frame 3 is achieved, thereby improving the stability of the mounting frame 3 during lifting and lowering.

[0033] It should be noted that a workbench 15 for support is fixedly installed at the bottom of the frame 1 , and the outer diameter of the workbench 15 is consistent with that of the frame 1 . By providing the workbench 15 , the effect of supporting the frame 1 is achieved.

[0034] It should be understood that slide rails 16 are fixedly installed on the left and right sides of the inner bottom wall of the workbench 15, and a receiving box 17 for receiving welding slag is slidably connected to the inner side of the slide rails 16. A movable door 18 is hinged on the front of the workbench 15, and a handle 19 is fixedly connected to the outer surfaces of the receiving box 17 and the movable door 18. By arranging the slide rails 16, the receiving box 17, the movable door 18 and the handle 19, when the welding robot body 11 is welding the automobile parts, the staff can open the movable door 18 in advance and then pull out the receiving box 17 to receive the welding slag dropped during the welding process, thereby preventing the welding slag from being scattered in the working area and being difficult to clean.

[0035] See also Figure 5 , filter boxes 20 are fixedly connected to the left and right sides of the frame 1, and an air suction fan 21 for sucking exhaust gas is fixedly installed inside the filter box 20. A cover plate 22 is arranged on the back of the filter box 20, and a slot 23 is opened on the back of the filter box 20. A plug block 24 is fixedly connected to the back of the cover plate 22, and the slot 23 and the plug block 24 are plugged and fixed. The front of the filter box 20 and the cover plate 22 are fixedly connected with an activated carbon filter 25. By setting the filter box 20, the air suction fan 21, the cover plate 22, the slot 23, the plug block 24 and the plug block 24, when in use, the staff only needs to start the air suction fan 21 to absorb and purify the exhaust gas generated during welding, and then discharge it to the outside, thereby avoiding exhaust gas polluting the working environment.

[0036] In addition, when the intake fan 21 needs to be cleaned, the staff only needs to pull out the cover 22 forcefully to release the plug-in fixation between the slot 23 and the plug block 24, and then remove the cover 22 to expose the intake fan 21. At this time, the staff can use a brush to brush off the dust on the blades of the intake fan 21.

[0037] In summary, when the welding manipulator for automated welding of automobile parts is in use, the staff can start the lifting cylinder 2 and the forward and reverse motor 8 through the controller, wherein the lifting cylinder 2 can drive the mounting frame 3 to rise and fall, thereby adjusting the horizontal height of the welding manipulator body 11. In addition, the forward and reverse motor 8 can drive the worm block 9 to rotate. When the worm block 9 rotates, since the worm block 9 and the worm 5 are in a meshing transmission state, the worm block 9 can move on the outer surface of the worm 5 through the teeth on its outer surface, thereby driving the welding manipulator body 11 to move laterally and adjust its position. Compared with the existing welding manipulators, it is more flexible. When facing larger automobile parts, it is not easy for the welding gun to be unable to reach, which is more convenient to use. When the manipulator body 11 performs welding processing on automobile parts, the staff can open the movable door 18 in advance, and then pull out the receiving box 17 outward, so as to receive the welding slag dropped during the welding process, thereby avoiding the welding slag from being scattered in the working area and being difficult to clean.
