Description

Technical Field

[0001] This utility model relates to the field of welding gun assembly technology, and in particular to an automated welding gun assembly for 3D spot welding. Background Technology

[0002] 3D electric welding is an advanced manufacturing process that integrates three-dimensional modeling and welding technology. Based on digital models, it uses electric arc welding to precisely weld metal materials into shape by layering them. By programming and controlling the movement trajectory of the welding torch, it can manufacture complex curved surfaces, internal hollows, and other structures that are difficult to achieve with traditional processing. It is widely used in aerospace and mold manufacturing fields. Compared with traditional manufacturing, it can significantly shorten the production cycle, reduce material waste, and effectively improve product customization capabilities and production efficiency.

[0003] Existing 3D welding processes use six-axis robotic arms. Although six-axis robotic arms can move flexibly in three-dimensional space, each robotic arm has its specific working range and is limited by the mechanical structure and joint movement angles. When working on small welding parts, multiple robotic arms need to work together to cover the entire working area, increasing the complexity and cost of the system. Existing technologies use multiple six-axis robotic arms to work together, and by rationally planning the working area and task allocation of each robotic arm, they can cooperate with each other to weld the parts from different angles and directions, improving the accessibility and flexibility of welding. However, using multiple six-axis robotic arms requires more production space, and the simultaneous use of multiple six-axis robotic arms also increases production energy consumption, greatly increasing production costs.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an automated welding gun assembly for 3D spot welding, comprising a machine tool 1. A base plate 15 is fixedly connected to the top right end of the machine tool 1. A fixing plate 18 is fixedly connected to the top of the base plate 15. A spindle 19 is rotatably connected to the upper middle part of the fixing plate 18. A disc 20 is fixedly connected to the outer right end of the spindle 19, and the disc 20 can drive the spindle 19 to rotate. A turntable 21 is rotatably connected to the outer middle part of the spindle 19. Multiple springs 22 are fixedly connected to the front and rear ends of the left side of the turntable 21. An adjusting rod 27 is fixedly connected to the left end of the spring 22. Multiple fixing blocks 23 are fixedly connected to the front and rear sides of the left end of the spindle 19. The fixing blocks 23 are slidably connected to the adjusting rod 27, and the adjusting rod 27 can slide within the fixing blocks 23. Multiple adjusting rods 25 are fixedly connected to the outer side of the fixing blocks 23. The right end of the adjusting rod 25 is fixedly connected to the disc 20, and the other end of the adjusting rod 25 is rotatably connected to the rotating shaft 26. The adjusting rod 25 is rotatably connected to the jaw 24 through the rotating shaft 26. The disc 20 can synchronously drive the jaw 24 to rotate. The control computer 3 is fixedly connected to the front left side of the top of the machine tool 1. The spray gun 4 is fixedly connected to the left side of the top of the machine tool 1. The cleaning mechanism 2 is fixedly connected to the rear side of the top of the machine tool 1. The cleaning mechanism 2 is used to clean the surface of the welding area of ​​the machine tool 1. The concave plate 6 is fixedly connected to the front side of the top of the machine tool 1. The baffle 5 is fixedly connected to the top of the concave plate 6, which can provide protection for the user during welding operations. Multiple welding blocks 13 are fixedly connected at equal intervals on the right side of the disc 20. The arc-shaped handle 14 is fixedly connected to the right side of the welding block 13, which makes it convenient for the user to pull and rotate the disc 20.

[0032] Specifically, a base plate 15 is installed on the top of the machine tool 1 to fix the fixed plate 18. A rotatable spindle 19 is installed on the top of the fixed plate 18. A disc 20 is welded to the right end of the spindle 19. Rotating the disc 20 can drive the spindle 19 to rotate. Multiple welding blocks 13 are distributed in a circular array on the right side of the disc 20. Each welding block 13 has an arc-shaped handle 14 firmly welded to its right side. This ergonomically designed arc-shaped handle 14 fits the hand's grip curvature, which not only makes it easier for the user to apply force accurately and achieve smooth pulling and flexible rotation of the disc 20, but also effectively reduces hand fatigue caused by long-term operation, greatly improving the convenience and efficiency of equipment use. A turntable 21 is installed in the middle of the spindle 19. Multiple springs 22 are installed on its left side. The other end of the springs 22 is connected to the adjusting rod 25. The elasticity of the springs 22 can pull the adjusting rod 25. A concave plate 6 is installed on the front of the top of the machine tool 1 by welding. A baffle 5 is vertically fixed above the concave plate 6. This protective structure is used during welding operations. This forms a solid barrier that effectively blocks sparks, high-temperature debris, and arc radiation generated during welding, creating a safety barrier for operators, significantly reducing operational risks, protecting personnel safety and health, and ensuring the smooth and orderly conduct of welding work. Multiple fixed blocks 23 are evenly welded to the left end of the main spindle 19. The bottom of each fixed block 23 can slide along an adjusting rod 25, while multiple adjusting rods 25 are fixed to its top. The other end of each adjusting rod 25 is connected to a jaw clamp 24 via a rotating shaft 26. Therefore, the jaw clamp 24 can rotate relative to the fixed blocks 23 via the rotating shaft 26. The adjusting rod 25 at the top of the jaw clamp 24 is fixed to the disc 20. Therefore, pulling and rotating the disc 20 opens the jaw clamp 24 and allows it to rotate. When the disc 20 is released, the elasticity of the spring 22 causes the jaw clamp 24 to tightly grip the weldment. This solves the problem that using multiple six-axis robotic arms requires more production space, and that the simultaneous use of multiple six-axis robotic arms increases energy consumption and significantly increases production costs.

[0033] Reference Figure 1 , Figure 3 and Figure 5The cleaning mechanism 2 includes a motor 201, which is mounted on the top right rear end of the machine tool 1. A bevel gear 202 is fixedly connected to the output end of the motor 201. A bevel gear 204 is meshed with the outer front end of the bevel gear 202. A threaded rod 208 is fixedly connected to the middle of the bevel gear 204. Turning on the motor 201 synchronously drives the bevel gear 204 to rotate. Multiple support plates 203 are rotatably connected to the front and rear ends of the threaded rod 208. Multiple support plates 203 are fixedly connected to the top of the machine tool 1. A concave plate 206 is fixedly connected to the top of each support plate 203. The bottom of the machine tool 1 has a groove 207. A slider 205 is threadedly connected to the middle outer side of the threaded rod 208. The slider 205 is slidably connected to the groove 207 and can slide within the groove 207. A brush 209 is fixedly connected to the bottom of the slider 205 for cleaning the surface of the machine tool 1. Multiple screws 17 are threadedly connected to the lower left side of the machine tool 1. A warning sign 16 is threadedly connected to the outer side of the screws 17 for warning purposes during operation. Load-bearing columns 9 are fixedly connected to the four corners of the bottom of the machine tool 1. Foot pads 10 are fixedly connected to the bottom of the load-bearing columns 9 to reduce the impact on the ground.

[0034] Specifically, a bevel gear 202 is welded to the output end of motor 201. A second bevel gear 204 is connected to the outer side of bevel gear 202, and a threaded rod 208 is welded through the middle of the second bevel gear 204. Therefore, when motor 201 is turned on, it drives the threaded rod 208 to rotate synchronously. Both ends of the threaded rod 208 can rotate within the support plate 203. Multiple threaded holes are arranged in an orderly fashion on the lower left side of machine tool 1. Through precise tightening, screws 17 are securely threaded to warning signs 16. These warning signs 16, with their conspicuous design and standardized warning messages, form a strong visual cue when machine tool 1 is running, effectively reminding surrounding personnel of the risks of equipment operation and preventing accidental approach or contact, thus building a solid visual warning defense line for safe production. A slider 205 is connected to the middle of the threaded rod 208, which can rotate threadedly on the threaded rod 208. A brush 209 is welded to the bottom of the slider 205. Four... At each corner, a load-bearing column 9 is vertically welded. Each load-bearing column 9 has a specially designed foot pad 10 installed at its bottom. These foot pads 10 are made of shock-absorbing and buffering material. By dispersing the vibration and pressure generated by the machine tool 1 during operation, they effectively alleviate the impact on the ground, not only protecting the workshop floor structure from damage, but also reducing equipment operating noise and providing reliable support for the stable operation of the machine tool 1. There is a concave plate 206 on the top of the slider 205. The groove 207 opened at the bottom of the plate allows the slider 205 to move back and forth within it and also restricts the movement of the slider 205. Therefore, when the motor 201 is started, it will synchronously drive the brush 209 at the bottom of the slider 205 to move back and forth to clean the surface of the welding area. This solves the problem that impurities on the surface of the welding area are not removed in time, which can lead to impurities entering the guide rails, lead screws, bearings and other key components of the machine tool 1 due to vibration and other reasons, aggravating the wear of the components and affecting the motion accuracy and stability of the machine tool 1.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A crossbeam 11 is fixedly connected to the lower right side of the machine tool 1, and a hook 12 is fixedly connected to the bottom of the crossbeam 11 for easy hanging of items by the user; a storage box 7 is slidably connected to the lower middle part of the machine tool 1, and a ball-shaped pull block 8 is fixedly connected to the front of the storage box 7 for easy temporary storage of items by the user.

[0036] Specifically, a crossbeam 11 is securely welded to the lower right side of machine tool 1, and a hook 12 is vertically installed at the bottom of the crossbeam 11, providing operators with a convenient hanging position for items, making the work area more tidy and orderly, and effectively improving work efficiency; a precision slide rail is set in the lower middle part of machine tool 1, and the storage box 7 slides smoothly through the slide rail. A spherical pull block 8 is installed in the center of the front side of the storage box 7. This design allows operators to conveniently store tools, parts and other items in it at any time, providing an efficient temporary storage solution for production operations, making the work area orderly and making it easier to retrieve items.

[0037] Working principle: By pulling and rotating the disc 20 to the right, the welded parts can be fixed and rotated. The machine tool 1 has a base plate 15 mounted on top to fix the fixing plate 18. A rotatable spindle 19 is mounted on top of the fixing plate 18. The disc 20 is welded to the right end of the spindle 19. Rotating the disc 20 drives the spindle 19 to rotate. A turntable 21 is mounted in the middle of the spindle 19, and multiple springs 22 are mounted on its left side. The other end of each spring 22 is connected to an adjusting rod 25. The elasticity of the springs 22 can pull the adjusting rod 25. Multiple fixing blocks 23 are evenly welded to the left end of the spindle 19. The bottom of each fixing block 23 can slide and be adjusted... The first section 25 has multiple adjusting rods 25 fixed at its top. The other end of the adjusting rod 25 is connected to the gripper 24 through the rotating shaft 26. Therefore, the gripper 24 can rotate relative to the fixed block 23 through the rotating shaft 26. The adjusting rod 25 at the top of the gripper 24 is fixed to the disc 20. Therefore, when the disc 20 is pulled and rotated, the gripper 24 can be opened and rotated. When the disc 20 is released, the elasticity of the spring 22 will make the gripper 24 tightly grip the welded part. This solves the problem that using multiple six-axis robotic arms requires more production space and that the simultaneous use of multiple six-axis robotic arms will increase production energy consumption and greatly increase production costs.

[0038] By turning on the motor 201, the brush 209 cleans the surface of the welding area of ​​the machine tool 1. Because the output end of the motor 201 is welded with a first bevel gear 202, and the outer side of the first bevel gear 202 is connected to a second bevel gear 204, while the middle of the second bevel gear 204 is welded through a threaded rod 208, when the motor 201 is turned on, it drives the threaded rod 208 to rotate synchronously. Both ends of the threaded rod 208 can rotate within the support plate 203. A slider 205 is connected to the middle of the threaded rod 208, which can rotate threadedly on the threaded rod 208. The bottom of the slider 205 is welded... The brush 209 is attached to the top of the slider 205, where there is a concave plate 206. The groove 207 at the bottom of the plate allows the slider 205 to move back and forth within it and also restricts the movement of the slider 205. Therefore, when the motor 201 is started, it will synchronously drive the brush 209 at the bottom of the slider 205 to move back and forth to clean the surface of the welding area. This solves the problem that if impurities on the surface of the welding area are not removed in time, they will enter the guide rails, lead screws, bearings and other key components of the machine tool 1 due to vibration and other reasons, which will aggravate the wear of the components and affect the motion accuracy and stability of the machine tool 1.
