The motor 25 has high power and torque output and can drive the gear 28 to rotate, realizing the linear movement of the moving component 2. The top of the support plate 29 is fixedly connected to the automatic lubrication pump 27. The automatic lubrication pump 27 is a small plunger pump, which can reduce friction and wear between components and extend the service life of the equipment. The bottom of the support plate 29 is rotatably connected to the gear 28. The gear 28 meshes with the rack 14. Driven by the motor 25, the gear 28 rotates and drives the support plate 29 to move linearly along the slide rail 13. The bottom of the support plate 29 is fixedly connected to multiple sliders 26. The inner sides of the multiple sliders 26 are slidably connected to the outside of the two slide rails 13.

[0027] The connecting assembly 3 includes a fixing plate a31, which is a rectangular steel plate. The top of the fixing plate a31 is fixedly connected to the bottom rear side of the truss device 21, providing a fixing point for the connection between the connecting assembly 3 and the truss device 21. A connecting plate 32 is fixedly connected to the bottom outer side of the connecting assembly 3. The connecting plate 32 connects the fixing plate a31 and the fixing plate b33, enhancing the overall strength and stability of the connecting assembly 3. A fixing plate b33 is fixedly connected to the bottom of the connecting plate 32. The bottom of the fixing plate b33 is fixedly connected to the top of the welding robot 4, securely mounting the welding robot 4 onto the connecting assembly 3. The bottom of the fixed plate a31 is fixedly connected to a protruding post 34. The protruding post 34 is cylindrical and is slidably connected to the inside of the fixed plate b33. The sliding connection between the protruding post 34 and the fixed plate b33 is achieved by threading positioning bolts 35 on both sides of the outside of the fixed plate b33. The ends of the two positioning bolts 35 are threaded to the inside of the fixed plate a31. After the position of the welding robot 4 is adjusted, the positioning bolts 35 are tightened to firmly fix the fixed plate a31 and the fixed plate b33, ensuring the positional stability of the welding robot 4 during operation and preventing the welding position from shifting due to vibration or collision.

[0028] Working principle: The control console 5 serves as the central control hub for the entire equipment. Operators input relevant commands and parameters on the console 5 to precisely control the actions of various parts of the equipment. The console 5 transmits the commands to the electrical control cabinet 23 in the moving component 2. After parsing and processing the commands, the electrical control cabinet 23 controls the motor 25 to start. Once started, the output shaft of the motor 25 drives the gear 28, which is rotatably connected to the bottom of the support plate 29, to rotate. Because the gear 28 meshes with the rack 14 fixedly connected to the horizontally similar side of the slide rails 13 on both sides of the inner wall of the sheet metal protective shell 11 in the base component 1, the rotation of the gear 28... The transition is transformed into the linear movement of the support plate 29 along the slide rail 13. At the same time, the inner sides of the multiple sliders 26 fixedly connected to the bottom of the support plate 29 are slidably connected to the outside of the two slide rails 13. The cooperation between the sliders 26 and the slide rails 13 not only provides guidance for the movement of the support plate 29 and ensures the smoothness of its linear movement, but also bears a certain load and ensures the stability of the equipment during operation. The truss device 21 is fixedly connected to the support plate 29. Therefore, as the support plate 29 moves linearly, the truss device 21 also moves linearly along the slide rail 13, realizing the horizontal movement of the truss system.

[0029] The top of the fixing plate a31 in the connecting assembly 3 is fixedly connected to the bottom rear side of the truss device 21. The connecting assembly 3 is fixedly connected to the top of the welding robot 4 through the connecting plate 32 fixedly connected to the bottom of the outer side and the fixing plate b33 fixedly connected to the bottom of the connecting plate 32, thereby mounting the welding robot 4 on the truss device 21 and enabling the welding robot 4 to move together with the truss device 21. The protrusion 34 fixedly connected to the bottom of the fixing plate a31 is externally slidably connected to the inside of the fixing plate b33. The ends of the positioning bolts 35 threaded on both sides of the outside of the fixing plate b33 are threaded to the inside of the fixing plate a31. After the position of the welding robot 4 is adjusted, tightening the positioning bolts 35 will firmly fix the fixing plate a31 and the fixing plate b33, ensuring the positional stability of the welding robot 4 during operation. When the truss device 21 drives the welding robot 4 to the designated working position, the welding robot 4 starts working according to the preset program and parameters. The welding gun 6, which is fixedly connected to the bottom of the welding robot 4, performs welding operations on the workpiece according to the set trajectory under the drive of the welding robot 4. The welding wire hopper 24, which is fixedly connected to the front of the truss device 21, provides welding wire for the welding process, ensuring the continuous operation of the welding operation. In addition, the automatic lubrication pump 27 in the moving component 2 can automatically provide lubrication for moving parts such as the rack 14, reducing friction and wear between parts, extending the service life of the equipment, and ensuring long-term stable operation of the equipment. The quick-connect system 15 set on the left side of the sheet metal protective shell 11 in the base component 1 facilitates the quick connection of other auxiliary equipment or tools when needed, improving the flexibility and applicability of the equipment.
