[0002] Welding robots are industrial robots that perform welding (including cutting and spraying). According to the International Organization for Standardization's definition of industrial robots as standard welding robots, an industrial robot is a multi-purpose, reprogrammable, automatically controlled manipulator with three or more programmable axes, used in the field of industrial automation. To adapt to different applications, the mechanical interface of the robot's last axis is usually a connecting flange, which can be connected to different tools or end effectors. Welding robots are industrial robots with welding clamps or welding (cutting) guns attached to the flange of the last axis, enabling them to perform welding, cutting, or thermal spraying.

[0003] According to application number CN202223487537.4, a welding robot with a stable moving structure is disclosed, including a welding robot body, a movable plate fixedly connected to the bottom end of the welding robot body, a worktable provided at the bottom of the movable plate, a buffer assembly provided inside the worktable, the buffer assembly including a fixed block, the fixed block being fixedly connected inside the worktable, a movable block being slidably connected inside the worktable, and a semi-circular groove being provided on one side of the movable block.

[0004] Although the welding robot in the above case has a translational effect, the translational structure and the welding robot are fixedly connected, making it inconvenient to disassemble the welding robot from the translational structure, reducing the flexibility during use. Moreover, the translational structure only has a unidirectional movement effect, which affects the welding robot's ability to weld in different directions. Therefore, we provide a welding robot with a stable movement structure. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-4 A welding robot with a stable moving structure includes a base 1, a moving adjustment component 2 on the base 1, a concave plate 3 on the moving adjustment component 2, a pluggable mounting seat 4 on the concave plate 3, the concave plate 3 and the mounting seat 4 being connected by a limiting and fixing component 5, and a welding robot body 6 being fixedly connected to the top of the mounting seat 4. The welding robot body 6 has been publicly described in the prior art, so it will not be elaborated on here.

[0021] The movable adjustment assembly 2 includes a servo motor 21, which is mounted on the left side of the base 1. A fixing groove 22 is provided on the top of the base 1. The right end of the output shaft of the servo motor 21 passes through the fixing groove 22 and extends into it, where a first adjusting rod 23 is fixedly connected. A first moving block 24 is threaded onto the surface of the first adjusting rod 23. The side of the first moving block 24 closest to the inner wall of the fixing groove 22 slides in contact with the inner wall of the fixing groove 22. A movable plate 25 is fixedly connected to the top of the first moving block 24, which passes through the fixing groove 22 and extends outwards. The bottom of the movable plate 25 is connected to the base. The top of the movable plate 25 has a sliding contact. The top of the movable plate 25 has a connecting groove 26. The front of the movable plate 25 is fixedly connected to a drive motor 27. The rear end of the output shaft of the drive motor 27 passes through the connecting groove 26 and extends into it, where a second adjusting rod 28 is fixedly connected. The surface of the second adjusting rod 28 is threadedly connected to a second moving block 29. The surface of the second moving block 29 slides in contact with the inner wall of the connecting groove 26. The top of the second moving block 29 passes through the connecting groove 26 and extends outward to be fixedly connected to the bottom of the concave plate 3. The bottom of the concave plate 3 slides in contact with the top of the movable plate 25.

[0022] The bottom of the inner wall of the fixed groove 22 and the bottom of the inner wall of the connecting groove 26 are both provided with sliding grooves 7. The bottom of the first moving block 24 and the bottom of the second moving block 29 are both fixedly connected with sliders 8 that are adapted to the sliding grooves 7. The bottom of the slider 8 passes through the sliding groove 7 and extends into it to slide in contact with the inner wall of the sliding groove 7. Several steel balls 9 are rotatably connected in the groove at the bottom of the slider 8. The end of the steel ball 9 near the inner wall of the sliding groove 7 rolls in contact with the inner wall of the sliding groove 7. By setting two sliding grooves 7 and two sliders 8, the stability of the first moving block 24 and the second moving block 29 during movement is improved, so that they will not rotate.

[0023] Servo motor 21 and drive motor 27 are electrically connected to an external controller, and the control circuit can be implemented by simple programming by those skilled in the art. This is common knowledge in the field and will not be elaborated further here.

[0024] The limiting and fixing assembly 5 includes slots 51 and fixing blocks 52. There are two slots 51, each located on the front of the recessed plate 3. Insert blocks 53, adapted to the slots 51, are fixedly connected to both sides of the mounting base 4. The side of the insert block 53 closest to the slot 51 penetrates the slot 51 and extends into it, contacting the inner wall of the slot 51. There are two fixing blocks 52, respectively installed on the left and right sides of the top of the movable plate 25. A reverse threaded rod 54 is rotatably connected to the groove of the right-side fixing block 52 via a bearing. The left end of the reverse threaded rod 54 penetrates the recessed plate 3 and extends into it. A forward threaded rod 55 is fixedly connected to the left end of the reverse threaded rod 54. The left end of the forward threaded rod 55, from right to left, penetrates the recessed plate 3 and the left-side fixing block 52, extending to the outside of the fixing block 52 and is fixedly connected to a rotating block 56. The right side of the rotating block 56 rotatably contacts the left-side fixing block 52. The rotating block 56 is made of hard rubber, increasing the friction generated when the fixing blocks 52 contact. To prevent the rotating block 56 from rotating on its own, threaded blocks 57 are threadedly connected to the surfaces of the reverse threaded rod 54 and the forward threaded rod 55. The bottom of the threaded block 57 slides in contact with the top of the movable plate 25. The threaded block 57 is square in shape, which ensures that the threaded block 57 will not rotate with the threaded rod. An adjusting block 58 is fixedly connected to the top of the threaded block 57. The side of the adjusting block 58 near the concave plate 3 is in contact with the concave plate 3. A locking block 59 is fixedly connected to the side of the adjusting block 58 near the insert block 53. A locking groove 510 is opened on the side of the insert block 53 near the locking block 59. The side of the locking block 59 near the locking groove 510 passes through the slot 51 and the locking groove 510 in sequence and extends into the inside of the locking groove 510, contacting the inner wall of the locking groove 510. Because the adjusting block 58 is L-shaped, when the locking block 59 is pulled out from the locking groove 510, the adjusting block 58 still remains in contact with the concave plate 3, so that the adjusting block 58 can only move left and right and will not rotate.

[0025] When it is necessary to separate the mounting base 4 and the concave plate 3, rotate the rotating block 56. The rotating block 56 drives the forward-rotating threaded rod 55 and the reverse-rotating threaded rod 54 to rotate, causing the two threaded blocks 57 to move away from each other. The threaded blocks 57 drive the locking block 59 away from the locking slot 510 through the adjusting block 58, so that the locking block 59 is pulled out of the locking slot 510. Then, pull the mounting base 4 forward. The mounting base 4 drives the insert block 53 to move forward, so that the insert block 53 and the slot 51 are separated, so that the mounting base 4 can drive the welding robot body 6 to be disassembled.

[0026] By setting the movable adjustment component 2, a bidirectional adjustment structure is formed in both the horizontal and vertical directions. Unlike the limitations of unidirectional translation in the existing technology, this design enables the welding robot body 6 to move bidirectionally along the XY axis in the horizontal plane, accurately adjust the welding position, and meet the precision requirements of multi-directional welding of complex workpieces. By setting the limit fixing component 5, the mounting base 4 and the concave plate 3 can be disassembled and assembled without tools, which significantly improves the adaptability of the equipment in different working scenarios, facilitates subsequent maintenance and repair, and ensures the stability of the connection between the concave plate 3 and the mounting base 4.

[0027] When in use, the servo motor 21 is started by an external controller, and its output shaft drives the first adjusting rod 23 to rotate. The threaded first moving block 24 slides in the fixed groove 22 along the horizontal X-axis direction. The first moving block 24 drives the movable plate 25 and the upper component to move horizontally as a whole. The steel ball 9 at the bottom of the slider 8 rolls into contact with the slide groove 7.

[0028] Start the drive motor 27, and its output shaft drives the second adjusting rod 28 to rotate. The threaded second moving block 29 slides in the connecting groove 26 along the longitudinal Y-axis. The second moving block 29 pushes the concave plate 3 and the welding robot body 6 to move longitudinally. Through bidirectional adjustment of the XY axis, it can be accurately positioned to any welding position of the complex workpiece. Then, the welding robot body 6 performs welding operations on the workpiece.
