[0017] Compared with the prior art, the present application has the following advantages: 1. This invention, through the design of a first connecting component, a cleaning component, and a transmission component, allows for the initial cleaning of the workpiece before welding with a welding torch. During welding, a pump operates, drawing air from the sealing ring and the cleaning component side through the first and second conduits of the first connecting component, and injecting the gas into the water tank to increase the pressure inside. This causes the liquid in the water tank to quickly enter the sealing shell. Due to the continuous accumulation of liquid and pressure inside the sealing shell, the internal liquid flows back to the water tank along the third connecting component, forming a circulation of liquid between the sealing shell and the water tank, thereby accelerating the heat dissipation of the welding torch. Simultaneously, when the liquid enters the sealing shell along the second connecting component, it flows from top to bottom... The liquid impacts the blades, squeezing them to rotate the sleeve. At this time, the second bevel gear drives the first bevel gear and the cleaning component to rotate, removing the welding slag from the welded area. This device converts the impact force of the falling liquid into the power of the blade rotation, realizing the secondary utilization of water resources. The second bevel gear is driven by the secondary water resources to rotate, which can also clean the rust spots on the surface of the welded workpiece. During the welding process, the blades continue to operate, ensuring that the device can continuously clean the welding slag on the surface of the welded workpiece. The air inlet on the surface of the cleaning component can recover waste gas and waste residue, which not only ensures the cleaning effect and welding quality of the welded workpiece, but also reduces the pollution of the device to the environment.

[0018] 2. This invention also incorporates a cleaning component and a pressure component. When the pump is running, the first connecting component extracts air from outside the cleaning plate to recover waste gas and slag generated during welding. The recovered waste gas and slag directly enter the water tank, are filtered by the screen plate inside the tank, and then enter the sealed shell. Subsequently, these waste gases and slag circulate in the device. After being filtered by the screen plate and adsorbed by the liquid, impurities are retained in the water tank, while excess air is discharged along the pump. This device can not only dissipate heat from the welding torch using liquid, but also drive the cleaning plate to clean the workpiece by the direction of liquid flow. At the same time, the device extracts waste gas and impurities from the air and reduces environmental pollution by using liquid adsorption and screen plate filtration, thereby improving resource utilization efficiency.

[0019] 3. This invention also designs a first connecting component, a second connecting component, and a third connecting component. When the welding torch angle is adjusted by the adjuster, the adjuster operates, causing the welding torch to rotate, thereby completing the angle adjustment. During this adjustment process, the sealing shell causes the first conduit connected to the second and third connecting components to rotate, which in turn causes the retaining ring below the second and third connecting components to rotate within the connecting chamber outside. This design allows the liquid to smoothly enter the first conduit along the connecting chamber, through the channel between the retaining ring and the first conduit, avoiding any impact on the adjustment of the welding torch caused by the connection between the sealing shell and the water tank, and ensuring the stability of the liquid flow between the sealing shell and the water tank.

In actual operation, the welding tool can realize the accurate positioning and automatic preliminary cleaning of the cleaning assembly 24 through the highly integrated mechanical arm 12 and the advanced automatic control system, and greatly reduce the demand for manual intervention.

[0023] Specifically, the mechanical arm 12 is not only responsible for accurately moving the cleaning assembly 24 to the position required for cleaning the surface of the workpiece to be welded, but also drives the cleaning assembly 24 to perform complex actions such as up and down, left and right, or rotation through the built-in high-precision servo motor or stepper motor system, to complete the comprehensive preliminary cleaning of the welding position of the workpiece to be welded. This process is completely controlled by the program, and the operator does not need to directly manually contact the workpiece, thereby ensuring that even in the welding scene of a workpiece with limited space or complex structure, efficient and accurate preliminary cleaning can be achieved, meeting the automation and precision requirements of high-standard welding.

The device not only can heat treat the welding gun 14 through the liquid, but also can drive the cleaning plate 241 to clean the workpiece to be welded by means of the flow direction of the liquid. At the same time, the device extracts the waste gas and impurities in the air, and reduces the pollution to the environment by using the liquid adsorption and the sieve plate 213 filtering method, thereby improving the resource utilization effect. In the design, the high-efficiency and controllable liquid circulation system is established between the sealing shell 231 and the water tank 212 through the third connecting assembly 26, when the pump 211 operates, in order to ensure that the liquid can smoothly return to the water tank 212, the backflow port is carefully designed on the sealing shell 231, so that the liquid can stably return; The design of the backflow port takes into account the dynamic characteristics of liquid flow, ensuring that when the pressure in the sealed shell 231 reaches a certain level, the liquid can flow into the third connecting assembly 26 through the backflow port by gravity and pressure difference, and ultimately return to the water tank 212, thereby setting a special valve structure (such as a one-way valve or a pressure regulating valve) at the backflow port, which can automatically open or close according to the pressure difference between the inside and outside of the sealed shell, thereby accurately controlling the backflow speed and amount of liquid.

[0025] In the embodiment of the present application, the pressure assembly 21 comprises a pump 211, which is connected to the water tank 212 below, and a sieve plate 213 is arranged in the water tank 212.

The snap ring 222 is connected to the first conduit 223 below. The second conduit 224 is fixedly connected above the connecting chamber 221.

Meanwhile, the sealing ring 27 is installed in the clamping groove 244 of the cleaning plate 241, and the clamping groove 244 is designed to have accurate size and shape to ensure that the sealing ring 27 does not displace or deform during rotation.

[0028] Working principle: the embodiment provides an industrial robot manufacturing welding tool, when in use, the position of the welding gun 14 is adjusted through the mechanical arm 12, and then the pressure assembly 21 is started. Then the mechanical arm 12 is adjusted, so that the cleaning assembly 24 is attached to the top of the welding position of the workpiece, and then the welding position of the workpiece is preliminarily cleaned from top to bottom, after the preliminary cleaning is completed, the cleaning assembly 24 returns to the top of the welding position of the workpiece, at this time, the welding gun 14 is started, and the workpiece is welded; After the preliminary cleaning of the welding parts, the welding gun 14 is used for welding treatment. During the welding process, the pump 211 is running, and the air on one side of the cleaning plate 241 and the sealing ring 27 is extracted through the first conduit 223 and the second conduit 224 of the first connecting assembly 22, and the gas is injected into the water tank 212, so as to increase the pressure in the water tank 212, and the liquid in the water tank 212 flows into the sealing shell 231 quickly.

During the adjustment process, the sealing shell 231 drives the first conduit 223 connected below the second connecting assembly 25 and the third connecting assembly 26 to rotate, thereby making the clamping ring 222 below the second connecting assembly 25 and the third connecting assembly 26 rotate in the connecting warehouse 221 outside the clamping ring 222, so as to ensure that the liquid can smoothly enter the first conduit 223 through the clamping ring 222 along the connecting warehouse 221; When the pump 211 is running, the air outside the cleaning plate 241 is extracted through the first connecting assembly 22, so as to recycle the waste gas and waste slag generated during the welding process.
