Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] As Figures 1-5 shown, a technical scheme provided by the utility model:

[0026] A robot welding mobile truss with damping performance, including base 1, the top end of base 1 is movably installed with truss body 2, damping mechanism is arranged between base 1 and truss body 2, damping mechanism includes mounting groove 6, mounting groove 6 is set up in the four corners and the middle two sides of base 1, spring damper 7 is fixedly installed in the inside of mounting groove 6, the output shaft end of spring damper 7 is fixedly connected to the bottom end of truss body 2, truss body 2 is movably connected with base 1 through spring damper 7, movable table 3 is movably installed on the upper end of truss body 2, guide groove 4 is set up in the middle of truss body 2, moving mechanism is arranged between movable table 3 and guide groove 4, moving mechanism includes rack 8, rack 8 is fixedly connected to the right side inner wall of guide groove 4, motor 9 is fixedly installed in the middle top right side of movable table 3, the output shaft of motor 9 is fixedly connected with gear 10 engaged with rack 8, guide rail 11 is fixedly connected to the upper end surface of truss body 2 and located at both sides of guide groove 4, the stability and linearity of movable table 3 in the moving process are ensured by the fixed installation of guide rail 11, and the bottom end of movable table 3 is slidably connected with guide rail 11;

[0027] In the embodiment, the lubricating mechanism cooperates with the moving mechanism, the lubricating mechanism moves synchronously with the movement of the moving mechanism, ensures that the meshing part of gear 10 and rack 8 is always fully lubricated in the moving process, and the dynamic lubrication mode not only improves the uniformity and timeliness of lubrication, but also avoids local wear caused by insufficient lubrication.

[0028] As Figure 2As shown, the oil tank 5 is fixedly installed at the middle bottom of the truss body 2, and a lubricating mechanism is arranged between the movable table 3 and the oil tank 5. The lubricating mechanism comprises an oil storage tank 12, which is fixedly installed at the right outer side of the movable table 3. The top end of the oil storage tank 12 is fixedly installed with an oil pump 13, the inlet end of the oil pump 13 is in communication with the inside of the oil storage tank 12, the right outer side of the oil tank 5 is communicated with a return oil pipe 14, a corrugated pipe 15 is detachably installed between the outlet end of the oil pump 13 and the return oil pipe 14, the bottom right side of the oil storage tank 12 is communicated with an oil outlet pipe 16, and the middle part of the oil outlet pipe 16 is fixedly installed with a proportional valve 17. The side of the oil tank 5 close to the return oil pipe 14 is inclined downward.

[0029] In this embodiment, the gravity lubrication mode is adopted, the lubricating oil drops to the meshing part of the gear 10 and the rack 8 through the oil outlet pipe 16, precise and uniform lubrication is realized, the delivery amount of the lubricating oil can be automatically controlled, the lubrication effect is moderate, and waste caused by excessive lubrication is avoided.

[0030] Further, through the cooperation of the oil tank 5 and the return oil pipe 14, the circulation of the lubricating oil is realized. The excess lubricating oil flows along the surface of the rack 8 under the action of gravity, is collected in the oil tank 5, and is returned to the oil storage tank 12 through the return oil pipe 14. The circulation mode not only reduces the waste of lubricating oil, but also reduces the operation cost of the equipment.

[0031] Working principle: when the truss body 2 is vibrated or impacted during welding, the spring damper 7 absorbs and slows down the vibration energy through the spring and damping device inside it, prevents the vibration from being transmitted to the base 1, and ensures the stability and precision of the welding process. On the basis of ensuring the stability of the truss by the damping mechanism, the moving mechanism realizes the precise movement of the movable table 3. After the motor 9 is started, its output shaft drives the gear 10 to rotate, the gear 10 is engaged with the rack 8 fixed on the inner wall of the guide groove 4, thereby driving the movable table 3 to slide along the guide rail 11. The precise control of the motor 9 enables the movable table 3 to move to the specified position according to the preset path, meeting the needs of the welding operation. The precise operation of the moving mechanism depends on the support of the lubricating mechanism. The lubricating mechanism delivers the lubricating oil from the oil storage tank 12 to the connection part of the rack 8 and the gear 10 through the action of gravity. After the proportional valve 17 is opened, the lubricating oil drops from the oil outlet through the oil outlet pipe 16, directly covering the meshing part of the gear 10 and the rack 8. The dropping amount of the lubricating oil is precisely controlled by the proportional valve 17, ensuring that the lubrication effect is moderate, neither the friction loss is intensified due to insufficient lubrication, nor the waste or pollution is caused by excessive lubrication. The lubricating oil is evenly distributed to the meshing surface through the rotational movement of the gear 10, effectively reducing the friction resistance between the gear 10 and the rack 8, reducing wear and prolonging the service life. The excess lubricating oil flows along the surface of the rack 8 under the action of gravity, and is finally collected in the oil tank 5. The side of the oil tank 5 close to the return oil pipe 14 is inclined downward, facilitating the return of the lubricating oil to the oil storage tank 12 through the return oil pipe 14, and realizing the circulation of the lubricating oil.
