[0002] The ball valve welding device mainly refers to the components and structures in the ball valve that are connected by welding. The valve body structure of the ball valve usually adopts integral welding. This structure can ensure the sealing performance of the valve body and avoid external leakage. The valve body of the ball valve can be connected to the pipeline or other components by welding. This connection method has high strength, corrosion resistance and good sealing performance. In the ball valve, the welding device mainly involves the connection between the valve body and the valve seat, valve stem and other components.

[0004] Furthermore, the vibration mechanism includes a fixed plate, a rectangular hole is provided on the top of the fixed plate, and the welding slag falling on the fixed plate falls into the rectangular groove through the rectangular hole. The setting of the rectangular hole reduces the contact area between the fixed plate and the welding slag, and prevents the welding slag from falling onto the surface of the fixed plate. A circular bottom plate is fixedly connected to one side of the fixed plate, and a folding tube is fixedly connected to the top of the circular bottom plate. The folding tube folds or stretches with the vibration of the spring, so that external welding slag cannot enter the interior, and the welding slag is prevented from affecting the vibration of the spring. The top of the folding tube is fixedly connected to a top plate, and the top plate is configured as a circular plate body with a circular groove on the bottom. The top of the top plate is fixedly connected to a magnetic suction cup. After the welded part is placed on the surface of the magnetic suction cup, the power supply of the magnetic suction cup is turned on, and the internal coil of the magnetic suction cup is energized to generate magnetic force, which tightly adsorbs and fixes the welded part in contact with the surface of the panel, ensuring that the welded part will not move or fall off during the cleaning process.

The electric telescopic rod drives the push block upward to push the top plate, and the spring is elastically deformed by the upward pulling force generated by the top plate. After the electric telescopic rod contracts downward, the pulling force generated by the top plate on the spring disappears, and the spring begins to recover its shape, causing the spring to continuously vibrate up and down along the cylindrical path. This vibration can effectively vibrate off the welding slag remaining on the surface of the welding part, and further collect the welding slag.

At the same time, the rectangular gradually retracting plate also plays a role in guiding the welding slag to fall into the filter screen. The bottom of the scraper is slidably connected to a filter screen, which filters welding slag to prevent the welding slag from direct contact with the magnet, thereby avoiding scratches or wear on the surface of the magnet caused by hard particles in the welding slag. A magnet is provided at the bottom of the filter screen, and the magnet directly attracts part of the welding slag that can be magnetically attracted to the surface of the filter screen through its strong magnetism, effectively improving the collection efficiency of the welding slag, and other welding slag falls onto the surface of the filter screen. The bottom of the rectangular gradually contracting plate is fixedly connected to the top of the workbench, one side of the collecting box is fixedly connected to the side of the workbench close to the rectangular inclined hole, the side of the corrugated sheet away from the scraper is fixedly connected to the inner wall of the rectangular groove, the bottom of the magnet is fixedly connected to the top of the rectangular groove, the outer surface of the electric telescopic rod 2 is fixedly connected to the inner wall of the circular groove, and a plurality of magnets are provided, and the plurality of magnets are distributed on the inner wall of the rectangular groove.

[0006] The present invention has the beneficial effects: 1. The present invention uses the annular baffle plate in the initial position when the welding part is not welded or welded, and its circular hole position is misaligned with the air outlet hole of the ventilation ring plate, so as to block the air outlet hole and prevent welding slag from entering the air outlet hole during welding, thereby protecting the air outlet hole from being blocked or damaged. The arc filter screen blocks the welding slag outside. After the welding part is placed on the surface of the magnetic suction cup, the power supply of the magnetic suction cup is turned on, and the internal coil of the magnetic suction cup is energized to generate magnetic force, so as to tightly adsorb and fix the welding part in contact with the surface of the panel, thereby ensuring that the welding part will not move or fall off during the cleaning process. The magnet directly attracts part of the welding slag that can be magnetically attracted to the surface of the filter screen through its strong magnetism, thereby effectively improving the collection efficiency of the welding slag, and other welding slag falls onto the surface of the filter screen, and the filter screen filters the welding slag to prevent the welding slag from directly contacting the magnet, thereby avoiding scratches or wear on the surface of the magnet caused by hard particles in the welding slag. The electric telescopic rod 2 drives the scraper to move, scrapes off the welding slag on the surface of the filter screen, and prevents the filter screen from being blocked.

[0007] 2. The present invention sets a chip blowing mechanism. When the welding part is not welded and is being welded, the annular baffle is in the initial position, and the circular hole position is misaligned with the air outlet hole of the ventilation ring plate, thereby blocking the air outlet hole and preventing welding slag from entering the air outlet hole during welding, thereby protecting the air outlet hole from being blocked or damaged. The arc filter screen blocks the welding slag outside. After the welding of the welding part is completed, the rotating block is rotated by hand to drive the annular baffle to rotate until the circular hole of the annular baffle is aligned with the position of the air outlet hole, and the fan starts to work to generate airflow, which passes through the ventilation ring plate and flows out from the air outlet hole. The airflow sweeps the surface of the welding part, the fixed plate and the magnetic suction cup, and blows impurities such as surface welding slag into the inside of the rectangular groove, further collects the welding slag, and at the same time blows the welding slag that may be attached to the surface of the arc filter screen into the inside of the rectangular groove, thereby preventing the welding slag from clogging the arc filter screen, resulting in obstruction of airflow and inability to blow away the welding slag.

[0008] 3. The present invention sets a vibration mechanism. After the welding piece is placed on the surface of the magnetic suction cup, the power supply of the magnetic suction cup is turned on, and the internal coil of the magnetic suction cup is energized to generate magnetic force, so that the welding piece in contact with the panel surface is tightly adsorbed and fixed, ensuring that the welding piece will not move or fall off during the cleaning process, and preventing the welding piece from falling and being damaged. The electric telescopic rod drives the push block upward to push the top plate, and the spring is elastically deformed by the upward pulling force generated by the top plate. After the electric telescopic rod is retracted downward, the pulling force generated by the top plate on the spring disappears, and the spring begins to recover its shape, causing the spring to continuously vibrate up and down along the cylindrical path. The cylindrical fixed spring vibration path prevents deviation. This vibration can effectively vibrate off the welding slag remaining on the surface of the welding piece, and further collect the welding slag. The welding slag falling on the fixed plate falls into the rectangular groove through the rectangular hole. The setting of the rectangular hole reduces the contact area between the fixed plate and the welding slag, and prevents the welding slag from falling onto the surface of the fixed plate. The folding tube folds or stretches with the vibration of the spring, so that the external welding slag cannot enter the interior, and the welding slag is prevented from affecting the vibration of the spring.

[0009] 4. The present invention provides a collecting mechanism, and the magnet directly attracts part of the welding slag that can be magnetically attracted to the surface of the filter screen through its strong magnetism, which effectively improves the collection efficiency of the welding slag, and other welding slag falls onto the surface of the filter screen, and the filter screen filters the welding slag to prevent the welding slag from directly contacting the magnet, avoiding the scratches or wear on the surface of the magnet caused by hard particles in the welding slag. The electric telescopic rod 2 drives the scraper to move, and scrapes off the welding slag on the surface of the filter screen to prevent the filter screen from being blocked. The corrugated sheet moves and extends accordingly, and the scraper is pushed to the rectangular inclined hole, and the welding slag slides into the collection box. The electric telescopic rod 2 contracts backward, and the corrugated sheet gradually restores the corrugation, and the welding slag that may remain on the corrugated sheet is bounced off to prevent incomplete collection of the welding slag. The rectangular gradually contracting plate prevents the welding slag from being bounced onto the surface of the workbench, effectively preventing the welding slag from being bounced onto the surface of the workbench when the corrugated sheet restores the corrugation, thereby maintaining the cleanliness and safety of the working environment. At the same time, the rectangular gradually contracting plate also plays a role in guiding the welding slag to fall into the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS

During the elastic deformation process, the elastic potential energy stored in the spring 1508 increases with the increase of deformation. After the electric telescopic rod 1510 contracts downward, the tension generated by the top plate 1505 on the spring 1508 disappears, and the spring 1508 begins to recover its shape. The elastic potential energy is converted into kinetic energy, causing the spring 1508 to continuously vibrate up and down along the path of the cylinder 1509. The welding slag remaining on the surface of the welded part is shaken off during the vibration, and the welding slag falling on the fixed plate 1501 falls into the rectangular groove 14 through the rectangular hole 1502. The folding tube 1504 folds or stretches with the vibration of the spring 1508, so that the external welding slag cannot enter the interior. The magnet 1806 directly absorbs part of the magnetically attracted welding slag to the surface of the filter 1805.After other welding slag falls onto the surface of the filter 1805, the electric telescopic rod 1801 drives the scraper 1802 to move, scraping off the welding slag on the surface of the filter 1805, and the corrugated sheet 1803 moves and stretches accordingly, and the scraper 1802 pushes the welding slag on the surface of the filter to the rectangular inclined hole 16, and the welding slag slides along the inclined surface of the rectangular inclined hole 16 to the inside of the collection box 1807, and the electric telescopic rod 1801 shrinks backward, and the corrugated sheet 1803 gradually restores the corrugation, and the welding slag that may remain on the corrugated sheet 1803 is bounced off, and the rectangular gradually shrinking plate 1804 is a rectangular annular baffle with a larger upper part and a smaller lower part, which surrounds the top of the rectangular groove 14 in an annular shape, blocks the welding slag bounced off by the corrugated sheet 1803, and prevents the welding slag from bouncing onto the surface of the workbench 1.
