Description

Technical Field

[0001] This utility model belongs to the technical field of welding torch cleaning equipment, specifically relating to an oil spraying mechanism for a welding torch cleaning station. Background Technology

[0002] In industrial production, welding is a key joining technology widely used in automobile manufacturing, machining, aerospace, and other fields. The quality of welding directly affects the performance, reliability, and service life of products, and the welding torch, as the core tool in the welding process, plays a decisive role in the welding quality.

[0003] A welding torch cleaning station is a device used to clean and maintain welding torch nozzles, ensuring that the welding torch remains in good working condition during use. The cleaning process typically includes scraping off oil and dirt from the nozzle surface, trimming wire, and spraying lubricating oil onto the nozzle surface. A welding torch cleaning station usually consists of three mechanisms: nozzle cleaning, wire trimming, and nozzle lubrication. The lubrication mechanism is a crucial component of the station. As the number of welded workpieces increases, the contact between the welding torch nozzle and the welding material increases, leading to wear. Therefore, the lubrication mechanism needs to replenish lubricating oil in a timely manner to protect the nozzle, reduce wear, and extend its service life.

[0004] However, some existing spraying mechanisms suffer from unstable spraying and consume a large amount of lubricating oil during spraying, resulting in high costs. Therefore, improvements are needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes an oil spraying mechanism for a welding torch cleaning station. The spraying process is stable and can prevent lubricating oil from splashing everywhere during spraying, ensuring a clean working environment. It can also recover excess lubricating oil, saving resources and reducing costs.

[0006] The technical solution of this utility model is implemented as follows:

[0007] An oil spraying mechanism for a welding torch cleaning station, applied to the welding torch cleaning station, includes: a fixed base, a nozzle, an air supply component, a solenoid valve manifold, a regulating valve, an oil supply bottle, an oil collection bottle, and a recovery channel fixed to the welding torch cleaning station; the fixed base has an oil spraying channel; the nozzle is located below the fixed base and extends into the oil spraying channel; the nozzle body has an oil inlet connector and an air inlet connector, the oil inlet connector being located above the air inlet connector; the air supply component is connected to the solenoid valve manifold via a hose, the solenoid valve manifold is connected to one end of the regulating valve via a hose, and the other end of the regulating valve is connected to the air inlet connector via a hose; the oil supply bottle is connected to the oil inlet connector, and the recovery channel is located below the oil spraying channel, the recovery channel being connected to the oil collection bottle.

[0008] In a preferred embodiment, the mounting base is provided with a nozzle adapter groove, which is connected to the oil injection channel.

[0009] In a preferred embodiment, the oil supply bottle and the oil receiving bottle are connected in communication.

[0010] In a preferred embodiment, the bottom of the recovery channel is inclined at an angle of 15°-30° to the horizontal plane, and an oil outlet is provided at the lowest end of the bottom of the recovery channel.

[0011] In a preferred embodiment, the recovery channel is provided with a filter screen, which is located upstream of the oil outlet.

[0012] Furthermore, a splash guard is provided around the recycling channel.

[0013] In a preferred embodiment, the gas supply component is a gas source processor.

[0014] In a preferred embodiment, the regulating valve is an exhaust throttle valve.

[0015] In a preferred embodiment, the oil supply bottle is equipped with a filter head.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This utility model proposes an oil spraying mechanism for use in a welding torch cleaning station. It includes a fixed base, a nozzle, an air supply component, a solenoid valve manifold, a regulating valve, an oil supply bottle, an oil collection bottle, and a recovery channel. In use, the welding torch nozzle can be placed on the fixed base, with the nozzle positioned below the fixed base and extending into it. The fixed base is equipped with an oil spraying channel, which prevents lubricating oil from splashing everywhere and improves the accuracy of oil spraying.

[0018] Furthermore, the oil inlet and air inlet connectors on the nozzle work together. The oil inlet connector connects to the oil supply bottle to introduce lubricating oil, while the air inlet connector introduces compressed air. This atomizes the lubricating oil and sprays it evenly onto the welding torch nozzle, effectively protecting the nozzle, reducing wear, and extending its service life. The air supply component provides the air source, and the solenoid valve manifold precisely controls the gas flow and flow rate (specifically, the solenoid valve is connected to the manifold; the solenoid valve controls the airflow, and the manifold directs the airflow to multiple ports). The regulating valve adjusts the gas pressure. Through the cooperation of the air supply component, the solenoid valve manifold, and the regulating valve, a high-pressure, stable airflow is provided to the air inlet connector.

[0019] In addition, the recycling channel and oil collection bottle recover excess lubricating oil during the spraying process, which not only saves lubricating oil resources and reduces usage costs, but also maintains a clean and hygienic working environment. Attached Figure Description

[0037] See Figures 1 to 4This utility model discloses an oil spraying mechanism for a welding torch cleaning station, including a fixed base 1, a nozzle 2, an air supply component 3, a solenoid valve manifold 4, a regulating valve 5, an oil supply bottle 6, an oil collection bottle 7, and a recovery channel 8, all fixed to the welding torch cleaning station. Specifically, the fixed base 1 has an oil spraying channel 101, and the nozzle 2 is positioned below the fixed base 1 and extends into the oil spraying channel 101. The nozzle 2 has an oil inlet connector 201 and an air inlet connector 202, with the oil inlet connector 201 located above the air inlet connector 202. The air supply component 3 is connected to the solenoid valve manifold 4 via a hose, and the solenoid valve manifold 4 is connected to one end of the regulating valve 5 via a hose. The other end of the regulating valve 5 is connected to the air inlet connector 202 via a hose. The oil supply bottle 6 is connected to the oil inlet connector 201, and the recovery channel 8 is located below the oil spraying channel 101 and is connected to the oil collection bottle 7. Specifically, in this oil spraying mechanism, the fixed base 1 serves to support the welding torch nozzle, providing it with a stable placement position. Nozzle 2 serves as the spraying component for applying lubricating oil. The upper part of nozzle 2 extends below the oil spraying channel 101 of the fixed base 1, which can prevent the sprayed lubricating oil from splashing everywhere and improve the accuracy of oil spraying. Secondly, the oil inlet connector 201 and air inlet connector 202 at the lower part of nozzle 2 are responsible for introducing lubricating oil and compressed air, respectively. Furthermore, the oil inlet connector 201 is connected to the oil supply bottle 6, and the air inlet connector 202 is connected to the air supply component 3. The air supply component 3 draws in gas, which passes through the solenoid valve manifold 4 and the regulating valve 5 before entering the air inlet connector 202. The gas flow rate at the air inlet connector 202 is relatively high, which can disperse the lubricating oil at the oil inlet connector 201 into a mist and spray it onto the welding torch nozzle. During this process, the solenoid valve manifold 4 can precisely control the on / off state and flow distribution of the gas, so as to flexibly adjust the oil spraying state according to actual needs. The regulating valve 5 is used to finely adjust the gas pressure to ensure that the gas pressure is stable and suitable. The two work together to provide a high-pressure and stable airflow to the air inlet connector 202, so that the gas sprayed from the air inlet connector 202 can effectively disperse and atomize the lubricating oil at the oil inlet connector 201, achieving uniform oil spraying. In addition, a recovery channel 8 is provided directly below the oil injection channel 101. The recovery channel 8 is connected to the oil collection bottle 7, which can recover excess lubricating oil during the oil injection process to the oil collection bottle 7, thereby realizing the recycling of lubricating oil, effectively saving material costs, and also maintaining a clean working environment.

[0038] It should be noted that the solenoid valve manifold 4 consists of a solenoid valve and a manifold. The solenoid valve is fixed on the manifold, and the gas supply component 3 is connected to the solenoid valve via a hose. The solenoid valve is mainly used to control the gas to form a stable airflow. Correspondingly, the manifold has multiple interfaces, one of which is connected to the regulating valve 5. Gas enters from the gas supply component 3, passes through the solenoid valve manifold 4, and is further directed to the nozzle 2.

[0039] In this embodiment, the air supply component 3 is an air source processor, which has higher stability and stronger environmental adaptability. Specifically, the air source processor consists of an air filter, a pressure reducing valve, and an oil mist lubricator. The air filter can filter impurities in the compressed air, the pressure reducing valve can stabilize the air pressure, and the oil mist lubricates the pneumatic components.

[0040] In this embodiment, the regulating valve 5 is an exhaust throttle valve. The exhaust throttle valve controls the exhaust flow rate, regulates the movement speed of the actuator, and reduces exhaust noise by adjusting the throttle orifice area. Using the exhaust throttle valve can ensure more stable and uniform oil injection and also reduce exhaust noise.

[0041] In this embodiment, the mounting base 1 is provided with a nozzle adapter groove 102, which is connected to the oil spray channel 101. Specifically, the diameter of the bottom of the nozzle adapter groove 102 is the same as the diameter of the oil spray channel 101, and the diameter of the nozzle adapter groove 102 gradually increases from bottom to top, so as to adapt to different types of welding torch nozzles. Smaller diameter welding torch nozzles can be fixed in the inner ring position along the nozzle adapter groove 102, while larger diameter nozzles are located in the outer position of the nozzle adapter groove 102, ensuring that all types of nozzles can be accurately connected to the oil spray channel 101. After spraying, excess lubricating oil can slide down from the inclined surface of the nozzle adapter groove 102 and the oil spray channel 101, drip into the recovery channel 8 and be recycled into the recovery bottle 7.

[0042] Preferably, the oil supply bottle 6 and the oil collection bottle 7 can be connected, that is, the two can share a container. The lubricating oil recovered from the welding torch cleaning process can flow back into the container, realizing the recycling of lubricating oil. This not only saves the cost of lubricating oil use, but also reduces the generation of waste, making it more environmentally friendly and efficient.

[0043] In this embodiment, the bottom of the recovery channel 8 is inclined at an angle of 15°-30° to the horizontal plane, and an oil outlet 801 is provided at the lowest point of the bottom of the recovery channel 8. Specifically, the inclined angle facilitates a more stable and natural flow of lubricating oil into the oil outlet 801, avoiding blockage. By connecting the oil outlet 801 and the oil collection bottle 7 with a hose, the lubricating oil flows along the inclined recovery channel to the oil collection bottle 7, recovering excess lubricating oil during spraying and saving costs.

[0044] Furthermore, a filter screen (not shown) is installed on the recovery channel 8. The filter screen is located upstream of the oil outlet 801. As the lubricating oil flows along the inclined recovery channel 8 to the oil outlet 801, the filter screen can effectively block various impurities such as welding slag and dust mixed in the lubricating oil, thereby ensuring the cleanliness of the lubricating oil recovered to the oil collection bottle 7, reducing the adverse effects of impurities on subsequent recycling, and also preventing impurities from causing blockages at the oil outlet 801 and the connecting hose.

[0045] Furthermore, a splash guard 802 is provided around the recycling channel 8. The height of the splash guard 802 is between 1cm and 2cm. During the process of lubricating oil dripping from the nozzle 2 into the recycling channel 8, the droplets may splash. The splash guard 802 can prevent the splashed lubricating oil from contaminating other areas, thereby maintaining the internal environment of the welding torch cleaning station.

[0046] Furthermore, the oil supply bottle 6 is equipped with a filter head (not shown in the figure). The filter head in the oil supply bottle 6 can filter the lubricating oil when it is drawn, remove impurities from the oil, prevent impurities from entering the oil injection system, ensure the quality of oil injection, and extend the service life of each component of the oil injection mechanism.

[0047] When the oil spraying mechanism is working, the air supply component 3 starts operating, outputting compressed air into the solenoid valve manifold 4. The solenoid valve manifold 4 precisely controls the on / off state and flow distribution of the gas according to a preset program or control signal, transporting the gas to the regulating valve 5. The regulating valve 5 further finely adjusts the gas pressure to ensure that the gas pressure entering the air inlet 202 is stable and meets the oil spraying requirements. Simultaneously, the compressed air output from the air supply component 3, after being regulated by the solenoid valve manifold 4 and the regulating valve 5, enters the air inlet 202, creating a negative pressure within the nozzle 2. Using the siphon principle, the lubricating oil from the oil supply bottle 6 is drawn into the nozzle 2 through the oil inlet 201. The compressed air entering the air inlet 202 meets the lubricating oil at the oil inlet 201, and the high-speed airflow atomizes the lubricating oil. Under pressure, the atomized lubricating oil is sprayed out from the nozzle 2, evenly spraying onto the surface of the welding torch nozzle located within the oil spraying channel 101, thus lubricating the welding torch nozzle. During the oil spraying process, excess lubricating oil flows through the spraying channel 101 into the lower recovery channel 8. The bottom of the recovery channel 8 is inclined at a certain angle to the horizontal plane to ensure that the lubricating oil flows smoothly into the outlet 801. As the lubricating oil flows towards the outlet 801, it passes through a filter screen installed on the recovery channel 8 to filter impurities and ensure that the lubricating oil is relatively clean. Subsequently, excess lubricating oil flows through a hose into the oil collection bottle 7, completing the lubricating oil recovery. When the oil spraying operation is completed, the solenoid valve manifold 4 controls the gas supply to stop, and the oil spraying process ends.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
