[0031] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 2 、 Figure 3 and Figure 4The utility model provides an embodiment: an automatic welding freight car robot, including a welding robot 1 and a slide rail 12. The welding robot 1 is the core component of the system, and its main function is to perform welding operations. It includes multiple welding heads and a control system, which can automatically weld the target workpiece. The bottom end of the welding robot 1 is fixedly connected to a base 2. The base 2 is the supporting structure of the welding robot 1, ensuring the stability of the robot during work. The inner wall of the slide rail 12 is slidably connected to a sliding block 3. The bottom end of the base 2 contacts the top of the sliding block 3. The slide rail 12 provides a horizontal movement space for the welding robot 1 through the sliding block 3, allowing the robot to move accordingly within the working area. The bottom inner wall of the sliding block 3 is fixedly connected to a hydraulic cylinder 4. The driving end of the hydraulic cylinder 4 is fixedly connected to a transmission block 5. The transmission block 5 is the direct drive part of the hydraulic cylinder 4, which is used to transmit the power of the hydraulic cylinder 4 and realize up and down movement.

[0033] The transmission block 5 is fixedly connected to the outside with multiple fixed plates 6. The inner wall of the fixed plate 6 is rotatably connected to a rotating plate 1 7. The outer side of the rotating plate 1 7 is rotatably connected to a rotating plate 2 8. The top inner wall of the rotating plate 2 8 is rotatably connected to a rotating block 9. The main function of the rotating plate 1 7 and the rotating plate 2 8 is to push the rotating block 9 through a rotational action. The far side of the multiple rotating blocks 9 is fixedly connected to a clamping plate 10. The rotating block 9 is an important link in the structure, responsible for converting the rotational motion into a force applied to the clamping plate 10. The far side of the multiple clamping plates 10 is in contact with the inner wall of the base 2. The bottom inner wall of the sliding block 3 is fixedly connected to multiple support seats 11. The outer wall of the rotating plate 2 8 is rotatably connected to the inner wall of the support seat 11. The setting of the multiple support seats 11 provides effective support for the rotating plate 2 8, ensuring its stable operation. The left and right sides of the slide rail 12 are fixedly connected to the limit plates 23. The left and right sides of the sliding block 3 are in contact with the adjacent sides of the two limit plates 23.

[0034] Reference Figure 1 、 Figure 2 and Figure 5 The front end of the slide rail 12 is fixedly connected to a clamping assembly for clamping freight cars. The core function of the clamping assembly is to clamp freight cars of different specifications to ensure stability during the welding process. The clamping assembly includes a placement plate 13. The rear end of the placement plate 13 is fixedly connected to the front end of the slide rail 12. The placement plate 13 has chambers 14 on both the left and right sides. The bottom inner wall of the chamber 14 is fixedly connected to a motor 15. The motor 15 is the key part that provides power for the clamping assembly. The driving end of the motor 15 is fixedly connected to a rotating plate 16. The top left and right sides of the rotating plate 16 are rotatably connected to transmission plates 17. The rotating plate 16 and the transmission plate 17 cooperate to convert the rotational motion into forward and backward movement.

[0035] The two transmission plates 17 are rotatably connected to the opposite sides of the chamber 14. The bottom inner wall of the chamber 14 is fixedly connected to two I-shaped groove blocks 19. The outer walls of the guide blocks 18 are slidably connected to the inner walls of the I-shaped groove blocks 19. The opposite sides of the two guide blocks 18 contact the front and rear inner walls of the chamber 14. The top of the guide blocks 18 is fixedly connected to a connecting rod 20. The function of the guide block 18 is to guide the forward and backward movement of the connecting rod 20 and provide a supporting role for the conversion movement. The top of the connecting rod 20 is fixedly connected to a clamping plate 21. The bottom sides of multiple clamping plates 21 are slidably connected to the top side of the placement plate 13. The connecting rod 20 connects the clamping plates 21 and the guide blocks 18, and its forward and backward movement directly affects the clamping effect. The top of the placement plate 13 is provided with multiple guide holes 22. The outer walls of the connecting rods 20 are slidably connected to the inner walls of the guide holes 22. The guide holes 22 provide guidance for the movement of the connecting rods 20, ensuring the stable trajectory of the clamping plates 21 during movement.

[0036] Working principle: When the welding robot 1 needs to be installed or replaced and maintained, the hydraulic cylinder 4 is turned on to generate power to drive the transmission block 5 to move up and down, so that the up and down movement of the transmission block 5 drives the fixed plate 6 to move up and down, and the up and down movement of the fixed plate 6 drives the rotating plate 1 7 to rotate, and the rotation of the rotating plate 1 7 drives the rotating plate 2 8 to rotate, so that the rotation of the rotating plate 2 8 on the inner wall of the support seat 11 drives the rotating block 9 to rotate, and the rotation of the rotating block 9 drives the pressing plate 10 to rotate, so that the pressing plate 10 can support the inner wall of the base 2 outward to fix the welding robot 1. The installation and maintenance of the welding robot 1 can be achieved by the drive of the hydraulic cylinder 4, which improves the installation efficiency and reduces the repair and maintenance costs.

[0037] By starting the motor 15 to generate power to drive the rotating plate 16 to rotate, the rotation of the rotating plate 16 drives the transmission plate 17 to rotate, and the rotation of the transmission plate 17 drives the guide block 18 and the connecting rod 20 to move back and forth. The back and forth movement of the connecting rod 20 drives the clamping plate 21 to move back and forth, and the clamping plate 21 can move back and forth to clamp freight cars of different specifications, ensuring that they are stable and immobile during the welding process. This helps prevent misalignment caused by vibration or thermal expansion during welding, thereby improving weld quality and strength.

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