Description

An arc welding room Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an arc welding chamber. Background Technology

[0002] Common welding methods include resistance welding, electric arc welding, gas welding, brazing, and laser welding. Electric arc welding is characterized by good welding quality and high production efficiency, and is widely used in industrial welding production. An arc welding room is a special space designed specifically for electric arc welding operations. It not only provides the environment required for welding operations, but also protects workers' health, improves work efficiency, and ensures work quality through a series of safety measures and technical means.

[0003] For example, Chinese Patent Publication No. CN216938901U discloses an arc welding protective room. This comparative patent achieves purification of welding fumes and dust generated during robotic welding by installing a duct fan and a welding fume purification device in the room. The room is equipped with a shielding plate to block the welding arc light, which can effectively block the arc light generated during welding and protect the physical and mental health of the workers.

[0004] However, the aforementioned comparative patent extends the air inlet of the duct fan into the room, making the height of the air inlet of the duct fan fixed. This results in the air inlet and the parts on the duct fan having a certain height, which makes it impossible to quickly and completely extract the exhaust gas generated during welding, resulting in incomplete exhaust gas extraction. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to propose an arc welding chamber to solve the problem that the exhaust port of the existing arc welding chamber is usually located at the top of the chamber and the height is not easy to adjust, resulting in a certain distance between the exhaust port and the parts, making it difficult to quickly and efficiently discharge the waste gas generated during welding, resulting in low waste gas collection efficiency.

[0006] To achieve the above objectives, this utility model provides an arc welding chamber, comprising a chamber body with an opening on one side and a roller shutter door at the opening. The chamber body also includes a clamp for holding parts and a welding robot for welding parts. A first fan is installed on the top of the chamber body, with its inlet extending into the chamber body and fitted with a waste gas collection hood. An adjustment component for adjusting the height of the waste gas collection hood is also installed inside the chamber body. A waste gas purification component is installed at the outlet of the first fan. A second fan is installed on the side of the chamber body, with its inlet located outside the chamber body and its outlet extending into the chamber body and fixedly connected to an outlet pipe. An airflow adjustment component is installed on the outlet pipe.

[0007] Preferably, the adjustment component includes a telescopic tube, one end of which is connected to the air inlet of the first fan and the other end of which is connected to the exhaust gas collection hood. A cylinder is installed inside the chamber, and the output end of the cylinder is connected to the exhaust gas collection hood, which is located above the clamp.

[0008] Preferably, the exhaust gas purification component includes a coolant tank installed on the top of the chamber, a spiral tube installed inside the coolant tank, one end of the spiral tube being connected to the air outlet of a fan, and a filter box being installed at the other end of the spiral tube.

[0009] Preferably, the filter box includes a box installed on the top of the chamber, and an activated carbon filter screen is installed inside the box.

[0010] Preferably, the air volume regulating component includes an air outlet hole formed in the air outlet pipe, a guide rail is installed on the air outlet pipe, a movable plate is slidably arranged in the guide rail, and a through hole of the same size as the air outlet hole is formed on the movable plate.

[0011] Preferably, an electric push rod is mounted on the end of the air outlet pipe via a bracket, and the output end of the electric push rod is connected to the movable plate.

[0012] The beneficial effects of this utility model are as follows: Since the exhaust gas collection hood is located above the fixture, its height can be adjusted by the adjustment component. This allows for adjustment of the collection height according to the actual size of the workpiece being clamped by the fixture, enabling the exhaust gas collection hood to collect exhaust gas more comprehensively and thoroughly, facilitating more complete extraction of exhaust gas from the chamber and improving the extraction efficiency. Furthermore, the airflow adjustment component allows for adjustment of the airflow in the exhaust duct, ensuring normal ventilation while preventing excessively rapid air convection inside and outside the chamber, which could affect the comfort of the chamber environment and facilitate normal work for the staff.

[0022] As shown in Figures 1, 2, 3, 4, and 5, an arc welding chamber includes a chamber body 1 with an opening on one side and a roller shutter door 2 at the opening. Inside the chamber body 1, there is also a clamp 3 for holding parts and a welding robot for welding parts. A fan 4 is installed on the top of the chamber body 1, with the air inlet of the fan 4 extending into the chamber body 1 and equipped with an exhaust gas collection hood 5. An adjustment component 6 for adjusting the height of the exhaust gas collection hood 5 is installed inside the chamber body 1. An exhaust gas purification component 7 is installed at the air outlet of the fan 4. A fan 8 is installed on the side of the chamber body 1. The fan 8 is a fixed-speed fan, with the air inlet of the fan 8 located outside the chamber body 1 and the air outlet extending into the chamber body 1 and fixedly connected to an exhaust pipe 9. An air volume adjustment component 10 is installed on the exhaust pipe 9.

[0023] Fan 1 4, together with exhaust gas collection hood 5, can collect exhaust gas generated during welding of chamber 1. Under the action of adjustment component 6, the height of exhaust gas collection hood 5 is adjustable, making the collection of exhaust gas more comprehensive. Exhaust gas purification component 7 can purify the collected exhaust gas, so as not to pollute the surrounding environment. Fan 2 8 can draw in outside air and transport it into chamber 1, so that the air in chamber 1 can circulate, making it convenient for workers to operate in chamber 1.

[0024] In a preferred embodiment of the present invention, the adjusting component 6 includes a telescopic tube 61, one end of which is connected to the air inlet of the fan 4, and the other end is connected to the exhaust gas collection hood 5. A cylinder 62 is installed inside the chamber 1, and the output end of the cylinder 62 is connected to the exhaust gas collection hood 5, which is located above the clamp 3.

[0025] When the height of the exhaust gas collection hood 5 needs to be adjusted, the cylinder 62 is activated, and the cylinder 62 pushes the exhaust gas collection hood 5 to move. Since the telescopic tube 61 has a certain degree of flexibility, the telescopic tube 61 will not obstruct the movement of the exhaust gas collection hood 5. It is convenient to adjust the collection height of the exhaust gas collection hood 5 according to the actual size of the workpiece clamped by the fixture 3, so that the exhaust gas collection hood 5 can collect exhaust gas more comprehensively and thoroughly, and it is convenient to extract the exhaust gas from the chamber more comprehensively and thoroughly, thus improving the extraction efficiency of exhaust gas.

[0026] In another preferred embodiment of the present invention, the exhaust gas purification component 7 includes a coolant tank 71 installed on the top of the housing 1, a spiral tube 72 installed inside the coolant tank 71, one end of the spiral tube 72 being connected to the air outlet of the fan 4, and a filter box 73 being installed at the other end of the spiral tube 72.

[0027] The filter box 73 includes a box 74 installed on the top of the chamber 1, and an activated carbon filter 75 is installed inside the box 74.

[0028] Fan 4 draws exhaust gas from chamber 1 through exhaust gas collection hood 5. The exhaust gas enters spiral tube 72 through the outlet of fan 4. Since spiral tube 72 is located in coolant tank 71, it can cool down the exhaust gas in spiral tube 72, preventing the exhaust gas with excessive temperature from being discharged to the outside. In addition, the spiral design of spiral tube 72 increases the cooling area, resulting in better cooling effect. The cooled exhaust gas enters filter box 73, and is filtered by activated carbon filter screen 75 before being discharged to the outside.

[0029] In another preferred embodiment of the present invention, the air volume regulating component 10 includes an air outlet hole opened in the air outlet pipe 9, a guide rail 101 is installed on the air outlet pipe 9, a movable plate 102 is slidably arranged in the guide rail 101, and a through hole of the same size as the air outlet hole is opened on the movable plate 102.

[0030] An electric push rod 103 is mounted on the end of the air outlet duct 9 via a bracket, and the output end of the electric push rod 103 is connected to the movable plate 102.

[0031] Since fan 8 is a fixed-speed fan, when it is necessary to adjust the air volume of the air outlet pipe, the air volume can be adjusted by changing the size of the air outlet hole. Activating the electric push rod 103 will push the moving plate 102 to move. The through hole on the moving plate 102 will be misaligned with the air outlet hole on the air outlet pipe 9, thereby partially blocking the air outlet hole and thus adjusting the air volume.

[0032] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0033] The embodiments of this utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
