Description

Technical Field

[0001] The utility model relates to the technical field of butt welding machines, in particular to a butt welding machine with self-exhausting smoke. Background Art

[0002] Butt welding machine, also known as spot welding machine, is a special equipment used to weld metal workpieces. It generates welding heat by applying high current between two or more workpieces for a moment to weld the workpieces together. Butt welding machine is mainly used for the connection of metal materials, such as steel plates, metal pipes, metal wires, etc.

[0003] For example, a welding machine disclosed in the authorization announcement number CN218612198U has a workbench, and a positioning mechanism and a welding mechanism are arranged on the workbench. The positioning mechanism includes a positioning seat, an upper limit assembly and a lower limit assembly. The positioning seat is provided with an upper positioning groove for positioning the second electronic component and a lower positioning groove for positioning the first electronic component. The lower limit assembly is provided with a positioning arm for positioning the first electronic component on one side close to the lower positioning groove. After adopting the above technical solution, the beneficial effects of the utility model are as follows: by setting the positioning seat, the lower limit assembly, the upper limit assembly, the first welding group and the second welding group, the problem of deviation or dislocation during welding is avoided, and at the same time, it has a single-sided or synchronous symmetrical welding function.

[0004] Although the above patent can avoid the problem of deviation or misalignment during welding, the above-mentioned butt welding machine will produce some harmful gases during the processing, such as carbon monoxide and sulfur dioxide. These harmful gases will diffuse around and be inhaled by the operators, which will cause damage to their own health and may cause poisoning. Utility Model Content

[0024] like Figure 1-Figure 4 As shown, a technical solution provided by the utility model:

[0025] A self-exhausting welding machine comprises a welding machine body 1, a lifting cylinder 2 is fixedly installed on one side of the top of the welding machine body 1, a welding head 3 is arranged on the output shaft end of the lifting cylinder 2, and a filter box 4 is arranged in the middle of the front side of the welding machine body 1 close to the welding head 3; a filtering mechanism is arranged on the inner side of the filtering box 4, and the filtering mechanism comprises a centrifugal pump 6, which is arranged inside the upper left end of the filtering box 4, and one end of the centrifugal pump 6 is connected to the suction port 5 through a connecting pipe 7, and the filtering mechanism also comprises a water tank 9, which is opened inside the right side of the filtering box 4, and a filter plate 10 is fixedly installed on the upper inner end of the water tank 9, and the other end of the centrifugal pump 6 is connected to the water tank 9 through a water inlet pipe 11, and the upper right outer end of the filtering box 4 is connected to an exhaust port 22;

[0026] In this embodiment, after the toxic gas is sucked into the suction port 5, it is poured into the water tank 9 through the water inlet pipe 11, filtered once by the water inside the water tank 9, and the filtered air is filtered twice by the filter plate 10 at the upper end, and finally discharged from the exhaust port 22. The toxic gas generated during spot welding is filtered twice, which can improve the filtering effect, and the toxic gas can be filtered and processed to prevent poisoning caused by inhalation by workers, thereby achieving the purpose of facilitating smoke exhaust.

[0027] like Figure 2 and Figure 4 As shown, a suction port 5 is provided on one side of the filter box 4 near the butt welding head 3, and an opening and closing mechanism is provided on the outer side of the filter box 4 located at the suction port 5, and the opening and closing mechanism includes a baffle 12, and the baffle 12 is movably installed on both sides of the outside of the filter box 4 near the suction port 5, and a pair of guide grooves 13 are provided on both sides of the filter box 4 near the suction port 5, and the baffle 12 and the guide groove 13 are movably connected through a second spring 14. The opening and closing mechanism also includes a bracket 16, and both sides of the bracket 16 are movably sleeved with a pressure rod 17, and the tops of the two pressure rods 17 are fixedly installed with a pressure frame 18, and one side of the top of the pressure frame 18 is movably arranged just below the bottom end of the butt welding head 3, and the pressure frame 18 and the bracket 16 are located outside the pressure rod 17. A first spring 19 is provided, and the bottom end of the pressure rod 17 passes through the bracket 16 and is fixedly installed with an inclined block 20, and the inside of the baffle 12 is provided with an inclined groove 21 matching the inclined block 20, and a positioning sensor 23 is provided at the lower middle part of the bracket 16, and the positioning sensor 23 is electrically connected to the centrifugal pump 6;

[0028] In this embodiment, the pressure frame 18 will be pressed down during the descent of the butt welding head 3, and the pressure frame 18 will drive the two pressure rods 17 to press down the inclined block 20. After the inclined block 20 is pressed into the inclined groove 21 at the top of the baffle 12, the two baffles 12 are controlled to be opened outward, and the pressure frame 18 will compress the first spring 19, and the other end of the baffle 12 will compress the second spring 14. As the baffle 12 opens, the positioning sensor 23 will sense it and then control the centrifugal pump 6 to start. After the centrifugal pump 6 is started, the toxic gas generated during spot welding will be sucked in through the suction port 5. As the butt welding head 3 is lifted, the baffle 12 will automatically close. In this way, when not in use, external debris can be prevented from entering the suction port 5, and smoke can be automatically exhausted during spot welding, which can achieve the purpose of energy saving.

[0031] Working principle: When working, the workpiece to be welded is placed just below the bottom end of the butt welding head 3, and then the lifting cylinder 2 is started. The lifting cylinder 2 controls the butt welding head 3 to descend to perform spot welding on the workpiece. During the process of the butt welding head 3 descending, the pressing frame 18 is pressed down, and the pressing frame 18 drives the two pressing rods 17 to press down the inclined block 20. After the inclined block 20 is pressed into the inclined groove 21 at the top of the baffle 12, the two baffles 12 are controlled to open outwards, and the pressing frame 18 will compress the first spring 19, and the other end of the baffle 12 will compress the second spring 14. As the baffle 12 is lowered, the pressure frame 18 will compress the first spring 19, and the other end of the baffle 12 will compress the second spring 14. The opening of the plate 12 will be sensed by the positioning sensor 23, and then the centrifugal pump 6 will be controlled to start. After the centrifugal pump 6 is started, the toxic gas generated during spot welding will be sucked in through the suction port 5. As the welding head 3 is lifted, the baffle 12 will automatically close, so that when not in use, external debris can be prevented from entering the suction port 5. When the toxic gas is sucked in by the suction port 5, it is poured into the water tank 9 through the water inlet pipe 11, and is filtered once by the water inside the water tank 9. The filtered air is then filtered twice by the filter plate 10 at the upper end, and finally discharged from the exhaust port 22.
