[0002] A welding robot is a multi-purpose, reprogrammable, automatically controlled welding automation equipment for industrial robots. A six-axis welding robot is usually used in the field of industrial automated welding. The end shaft of the six-axis robot arm is a mechanical interface, a connecting flange that can be connected to different jigs or end fixtures. A welding robot is a multi-purpose, reprogrammable, automatically controlled welding automation equipment for industrial robots. A six-axis welding robot is usually used in the field of industrial automated welding. The end shaft of the six-axis robot arm is a mechanical interface, a connecting flange that can be connected to different jigs or end fixtures. A welding robot is an industrial robot that is equipped with a welding tongs or welding gun on the end shaft flange to enable welding. Iron, carbon steel, and stainless steel can all be welded by welding robots. Double-container welding and argon arc welding are basically used more often. Manual welding can basically be replaced by welding robots.

[0003] During operation, the wrist of a welding robot rotates multiple times to move the welding head to the designated position and perform welding. The reciprocating friction gradually increases the friction of the wrist, so lubrication is required. The current lubrication method mostly adds a large amount of lubricating oil to the rotating position of the wrist at one time. If the lubricating oil evaporates and cannot be replenished in time, the lubrication effect will undoubtedly fail. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 5 As shown, the present invention is a welding robot wrist transmission mechanism with a lubrication structure, comprising a welding robot 1, wherein a lubrication mechanism 2 is installed at the wrist transmission position of the welding robot 1;

[0029] The lubrication mechanism 2 includes an arc-shaped plate 21 mounted on the lower side of the wrist transmission position of the welding robot 1. An outlet 22 is provided at the lowest position of the arc-shaped plate 21, and a magnetic table base 23 is installed on the side of the arc-shaped plate 21.

[0030] The lubrication mechanism 2 includes a mounting plate 24 installed on the lower side of the wrist transmission position of the welding robot 1, and an oil receiving box 25 is installed at the end of the mounting plate 24. The oil receiving box 25 is located directly below the outlet 22, and a piston tube 26 is installed at the bottom of the oil receiving box 25. An oil inlet groove 27 is provided directly above the piston tube 26. A plug body 28 is slidably installed inside the piston tube 26. An electric push rod 29 is installed on the side of the oil receiving box 25. The output end of the electric push rod 29 is connected to the plug body 28, the output end of the piston tube 26 is connected to a hose 210, and the output end of the hose 210 is connected to a connector 211. The output end of the connector 211 is placed at the lubrication position of the wrist transmission position of the welding robot 1.

[0031] In this embodiment, when using a welding robot wrist transmission mechanism with a lubricating structure, the arc plate 21 is first installed directly below the robot wrist, and then the magnetic base 23 can be directly installed and fixed by adsorption. Then, the mounting plate 24 is installed on the lower side so that the upper side of the oil receiving box 25 is directly opposite the lower side of the outlet 22. Then, two-thirds of the lubricating oil is injected into the oil receiving box 25, and the electric push rod 29 can be set to run at a fixed time, and then it can be used.

[0032] The electric push rod 29 operates, driving the plug body 28 to move in the piston tube 26. When the front end of the plug body 28 moves to the oil inlet groove 27 and opens, the oil in the oil receiving box 25 will flow into the piston tube 26 under its own weight. Then the electric push rod 29 moves forward, pushing the oil in the piston tube 26 into the hose 210. It should be noted that after the plug body 28 moves forward into place, the plug body 28 still blocks the oil inlet groove 27 to prevent excessive oil from flowing into the space behind the tail of the plug body 28. Then, after the oil in the hose 210 is filled, it will flow into the wrist transmission position of the robot through the connector 211, thereby achieving the purpose of lubrication.

[0033] The overflowed lubricating liquid will be collected by the arc plate 21 and flow into the oil receiving box 25 from the outlet 22, so as to achieve the purpose of recycling and saving energy.

[0034] Preferably, the contact surface between the arc plate 21 and the welding robot 1 is provided with oil-absorbing cotton. Such a design can absorb the oil sliding down from the wrist along the robot arm and guide it to drip toward the outlet 22. In fact, oil absorption and collection measures can also be considered according to specific circumstances.

[0035] Preferably, an observation window is provided on the side of the oil receiving box 25. Such a design allows the oil amount in the oil receiving box 25 to be observed. In fact, a structure that facilitates observation of the oil amount inside the oil receiving box 25 may also be considered according to specific circumstances.

[0036] The preferred connector 211 includes a threaded head 2111, a hexagonal screw cap 2112 is installed on the outside of the threaded head 2111, a connecting tube 2113 is rotatably installed on the input end of the threaded head 2111, and the connecting tube 2113 is connected to the output end of the hose 210. This design realizes a threaded connection with the robot wrist, ensuring the connection strength, and the rotation of the threaded head 2111 does not affect the connecting tube 2113, ensuring the connection effect. In fact, the structure of the connector 211 can also be considered according to specific circumstances.

[0037] Preferably, a one-way valve 212 is installed in the piston tube 26. Such a design prevents backflow and facilitates pushing the oil into the hose 210. In fact, measures that facilitate pushing the oil into the hose 210 can also be considered according to specific circumstances.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
