Description

Technical Field

[0001] This invention relates to the field of metal welding technology, and more specifically, to a welding apparatus for processing metal fixing plates. Background Technology

[0002] Welding equipment for metal plate processing is a specialized device used for fixing and welding metal plates. It is widely used in the field of metal processing. Common welding equipment includes spot welding machines, argon arc welding machines, and laser welding machines.

[0003] The working principle of an electric welding machine is to apply pressure to a metal plate through electrodes, and use the resistance heat generated by the current passing through the contact point to melt the metal, thereby achieving welding. Its characteristics include high welding speed, small heat-affected zone, and high weld strength, making it suitable for thin plate welding. For example, spot welding machines are widely used in automobile manufacturing to weld the thin metal sheets of the car body. The working principle of an argon arc welding machine is to use argon gas as a shielding gas to generate an electric arc through electrodes, converting electrical energy into heat energy to melt the base material and filler wire, forming a weld. Its characteristics include high weld quality, aesthetically pleasing welds, and the ability to weld various metal materials, such as stainless steel and aluminum alloys. However, the welding speed is relatively slow and the technical requirements for operators are high. It is often used in occasions where welding quality requirements are high, such as aerospace, food machinery, and medical device industries. The working principle of laser welding machine is to use a high energy density laser beam as a heat source to rapidly melt and solidify metal materials to achieve welding. Its characteristics are high welding precision and small heat-affected zone. Automatic welding machine can adjust the welding gun stroke and angle according to the weld shape to achieve automated welding. However, the equipment cost is high and the requirements for the working environment are strict. It is suitable for precision welding in fields such as microelectronics, precision instruments, and automotive parts.

[0004] Currently, existing technologies require repeated welding with a welding torch on the welding surface to form a thick and strong weld when welding two thick metal plates. Each welding operation requires pausing to manually scrape off and remove the weld slag before welding again to ensure weld strength. However, the need for multiple pauses and manual slag removal during welding is time-consuming and labor-intensive, which can easily affect welding efficiency. Therefore, this technology does not meet the current requirements. To address this, we propose a welding device for processing metal fixed plates. Summary of the Invention

[0028] To make the above-described objects, features, and advantages of this disclosure more apparent and understandable, specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this disclosure. However, this disclosure can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this disclosure. Therefore, this disclosure is not limited to the specific embodiments disclosed below.

[0029] In the description of this disclosure, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements, which will not be repeated here.

[0030] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0031] According to some embodiments of this disclosure, a welding apparatus for processing metal fixing plates is provided, with reference to... Figure 1 — Figure 8 As shown, the welding device for processing metal fixing plates includes an automatic welding machine 100, a crossbeam 110 movably disposed on the side of the automatic welding machine 100, a mounting block 120 slidably disposed on the side of the crossbeam 110, and a welding torch 130 disposed on the side of the mounting block 120 for welding the fixing plates. Two fixing plates to be welded are positioned by a clamp (not shown in the figure) and thus fixed on the automatic welding machine 100. A protective cover 140 is fixedly mounted on the outside of the mounting block 120, and the protective cover 140 is also slidably disposed on the side of the crossbeam 110. The crossbeam 110 is driven by a driving mechanism. Driven by a hydraulic cylinder or pneumatic cylinder, the crossbeam 110 can move back and forth and rise and fall on the side of the automatic welding machine 100. The mounting block 120, driven by a hydraulic cylinder or pneumatic cylinder, can move left and right on the crossbeam 110. These are all technical means well-known to those skilled in the art and will not be elaborated upon here. A sliding frame 150 is slidably mounted inside the protective cover 140 via a slide rail, allowing the sliding frame 150 to reciprocate stably within the protective cover 140. A scraper 160 is mounted on the outside of the sliding frame 150, and the scraper 160 is made of a high-temperature resistant metal, such as... Figure 2 and Figure 6 As shown, both the left and right sides of its working end have narrow and thin hard blades that fit the weld seam, which facilitates the scraper 160 to press against the weld slag and move left and right to scrape off the weld slag. A connecting block 161 is fixedly installed on the lower side of the sliding frame 150. The upper end of the scraper 160 is slidably inserted into the inner side of the connecting block 161. A first spring 162 is provided on the inner side of the connecting block 161. One end of the first spring 162 is fixedly connected to the inner wall of the connecting block 161, and the other end of the first spring 162 is fixedly connected to the top of the scraper 160.

[0032] A rotating shaft 163 is rotatably connected to the side wall of the protective cover 140 via a bearing. A drive gear 164 is fixedly mounted at one end of the rotating shaft 163 located outside the protective cover 140. A first rack 165 is fixedly mounted on the side of the crossbeam 110, and the first rack 165 meshes with the drive gear 164. Figure 2 and Figure 3 As shown, the side wall of the slide frame 150 has a slot, and the middle part of the rotating shaft 163 is slidably inserted into the slot in the side wall of the slide frame 150, so that the slide frame 150 can slide left and right relative to the rotating shaft 163 without being obstructed by the rotating shaft 163. A first sector gear 166 is fixedly installed at one end of the rotating shaft 163 located inside the slide frame 150, and a second rack 167 is fixedly installed on the upper side of the inner wall of the slide frame 150. The second rack 167 intermittently meshes with the first sector gear 166. A second sector gear 168 is also fixedly installed at one end of the rotating shaft 163 located inside the slide frame 150, and a second rack 168 is fixedly installed on the lower side of the inner wall of the slide frame 150. A third rack 169 is installed, which intermittently meshes with the second sector gear 168. When the second rack 167 meshes with the first sector gear 166, the teeth of the second sector gear 168 move away from the third rack 169, causing the third rack 169 to disengage from the second sector gear 168. When the teeth of the first sector gear 166 move away from the second rack 167, the second rack 167 disengages from the first sector gear 166. At this time, the second sector gear 168 moves closer to the third rack 169, causing the second sector gear 168 to begin meshing with the third rack 169.

[0033] A cleaning brush 170 is rotatably mounted inside the protective cover 140. A first pulley 171 is interference-fitted onto the center of the rotating shaft 163. A second pulley 172 is rotatably mounted on the inner side of the protective cover 140 via a bearing. A first transmission belt 173 is fitted between the first pulley 171 and the second pulley 172. The cleaning brush 170 is fixedly mounted on the outer side of the second pulley 172. A dust collection box 180 is fixedly connected to the outer side of the protective cover 140. The dust collection port of the dust collection box 180 communicates with the protective cover 140 and is close to the cleaning brush 170. The first transmission belt 173 is arranged in a figure-eight shape, causing the mounting block 120 to drive... When the welding torch 130 moves to the left along the crossbeam 110 to weld the two fixed plates, the first transmission belt 173, the first pulley 171 and the second pulley 172 work together to make the second pulley 172 drive the cleaning brush 170 to rotate counterclockwise, thereby sweeping the scraped welding slag into the dust collection box 180. The diameter of the first pulley 171 is smaller than the diameter of the second pulley 172, which slows down the rotation of the cleaning brush 170, so that the scraper 160 can quickly scrape off the welding slag, while the cleaning brush 170 can clean the welding slag at a slower and more reasonable rotation speed.

[0034] The bottom of the suction port of the dust collection box 180 is designed with an inclined slope. The rotating cleaning brush 170 pushes the welding slag over the highest point of the slope, causing the welding slag to slide down and accumulate on the inside of the dust collection box 180. The inclined suction port prevents the welding slag from falling back. The upper side of the inner wall of the suction port of the dust collection box 180 is fixedly installed with scraper teeth 181. The scraper teeth 181 are used in conjunction with the cleaning brush 170. When the cleaning brush 170 rotates and passes through the scraper teeth 181, the scraper teeth 181 comb the bristles of the cleaning brush 170, thereby scraping the welding slag adhering to the cleaning brush 170 into the dust collection box 180.

[0035] A third pulley 182 is interference-fitted into the middle of the rotating shaft 163. A shaft 183 is rotatably connected to the side wall of the dust collection box 180 via bearings. A fourth pulley 184 is fixedly installed at one end of the shaft 183 outside the dust collection box 180. A second transmission belt 185 is fitted between the third pulley 182 and the fourth pulley 184. A first bevel gear 186 is fixedly installed at one end of the shaft 183 inside the dust collection box 180. A second bevel gear 187 is rotatably installed inside the dust collection box 180 via bearings, meshing with the first bevel gear 186. A turbine 188 is coaxially mounted inside the dust collection box 180 with the second bevel gear 187. A filter 189 is installed inside the dust collection box 180. Figure 7As shown, the outer side of the filter screen 189 is fixedly connected to the inner wall of the dust collection box 180. The filter screen 189 isolates the turbine 188 from the dust collection port of the dust collection box 180, thereby separating the welding slag inside the dust collection box 180 from the turbine 188. An exhaust port is provided on the right side of the dust collection box 180. When the turbine 188 rotates, air is drawn in from the dust collection port on the left side of the dust collection box 180, flows through the filter screen 189 and the turbine 188, and is discharged into the air through the exhaust port on the right side of the dust collection box 180. The airflow path is short, which can effectively form a strong suction at the dust collection port, thereby drawing the scraped welding slag into the dust collection box 180. The diameter of the third pulley 182 is larger than the diameter of the fourth pulley 184, which increases the rotation speed of the fourth pulley 184, causing the turbine 188 to rotate at high speed, thereby giving the dust collection port of the dust collection box 180 sufficient suction to draw the welding slag into the dust collection box 180 for further cleaning.

[0036] The dust collection box 180 has a slag discharge port 190 at its bottom. A baffle 191 is slidably inserted into the inner wall of the bottom of the dust collection box 180, which closes the slag discharge port 190. A push rod 192 is also slidably inserted into the inner wall of the bottom of the dust collection box 180. One end of the push rod 192 located inside the dust collection box 180 is fixedly connected to the baffle 191, and one end of the push rod 192 located outside the dust collection box 180 intermittently contacts the side of the automatic welding machine 100. A second spring 193 is provided in the inner wall of the bottom of the dust collection box 180. One end of the second spring 193 is fixedly connected to the inner wall of the dust collection box 180, and the other end of the second spring 193 is fixedly connected to the baffle 191. A slag collection hole 194 is provided on the upper side of the automatic welding machine 100, which intermittently connects with the slag discharge port 190.

[0037] After a welding operation is completed, when the mounting block 120 drives the welding torch 130 and the protective cover 140 to reset, the slag collection hole 194 aligns with the slag discharge port 190, and the push rod 192 abuts against the side of the automatic welding machine 100. The push rod 192 pushes the baffle 191, opening the slag discharge port 190, so that the welding slag in the dust collection box 180 falls into the slag collection hole 194 through the slag discharge port 190. A collection bucket connected to the slag collection hole 194 can also be set in the automatic welding machine 100 to facilitate the collection and cleaning of welding slag. When welding two fixed plates are welded by the welding torch 130, the sliding frame 150 drives the scraper 160 to press against the weld seam of the fixed plate and move back and forth quickly to scrape off the welding slag. Then, with the cooperation of the cleaning brush 170 and the dust collection box 180, the welding slag is cleaned into the dust collection box 180, thereby quickly cleaning the welding slag while welding and improving welding efficiency.

[0038] Through the above technical solution, the welding device for processing metal fixing plates provided in this disclosure, when in use, fixes two metal fixing plates to be welded onto the automatic welding machine 100 using a clamp. After the drive mechanism moves the crossbeam 110 to the corresponding welding height, the mounting block 120 is driven to move to the left along the crossbeam 110, driving the welding torch 130 to weld along the weld seam. The protective cover 140 moves synchronously with the mounting block 120. The protective cover 140 also drives the drive gear 164 to move, so that the drive gear 164 meshes with the first rack 165 and rotates. Then, through the rotating shaft 163, it drives the first sector gear 166 and the second sector gear 168 to rotate synchronously. When the second sector gear 168 separates from the third rack 169, the first sector gear 166 meshes with the second rack 167, so that the second rack... 167 drives the sliding frame 150 to move to the left, thereby causing the sliding frame 150 to press the scraper 160 against the weld and move to the left to scrape off the welding slag. Immediately afterwards, the first sector gear 166 separates from the second rack 167, while the second sector gear 168 meshes with the third rack 169, causing the third rack 169 to drive the sliding frame 150 to move to the right, thereby causing the sliding frame 150 to press the scraper 160 against the weld and move to the right to continue scraping off the welding slag again. Thus, the sliding frame 150 and the scraper 160 are always pressed against the weld surface under the elastic force of the first spring 162. As the sliding frame 150 moves back and forth, the welding slag generated during welding is scraped off from the weld surface. The scraping action is completed within the protective cover 140, thereby avoiding the slag splattering when scraping the welding slag quickly.

[0039] At the same time, the rotating drive gear 164 drives the first pulley 171 to rotate synchronously through the rotating shaft 163, and transmits the rotation to the second pulley 172 through the first transmission belt 173. This causes the second pulley 172 to drive the cleaning brush 170 to rotate counterclockwise, sweeping the scraped welding slag into the dust collection box 180. Since the diameter of the first pulley 171 is smaller than that of the second pulley 172, the cleaning brush 170 is decelerated, so that the rotation speed of the cleaning brush 170 matches the scraping rate of the scraper 160, ensuring the cleaning effect.

[0040] In addition, the rotating shaft 163 also synchronously drives the third pulley 182 to rotate, which is transmitted to the fourth pulley 184 via the second transmission belt 185. Because the diameter of the third pulley 182 is larger than that of the fourth pulley 184, the fourth pulley 184 achieves a speed-increasing transmission, causing the fourth pulley 184 to drive the first bevel gear 186 to rotate at high speed. Through the cooperation of the first bevel gear 186 and the second bevel gear 187, the second bevel gear 187 drives the turbine 188 to rotate at high speed, quickly expelling the air from the dust collection box 180, thus making the dust collection box... A negative pressure environment is created inside the dust collection box 180, generating suction at the suction port of the dust collection box 180. Smaller and lighter welding slag is sucked into the dust collection box 180. At the same time, the cleaning brush 170 sweeps larger and heavier welding slag into the dust collection box 180, thus effectively cleaning the welding slag. The filter screen 189 isolates the turbine 188 from the suction area to prevent welding slag from entering the turbine 188 and causing damage to the components. When the cleaning brush 170 rotates and passes through the scraper teeth 181, the scraper teeth 181 comb the bristles and scrape the welding slag adhering to the bristles into the dust collection box 180.

[0041] Finally, after a welding operation is completed, when the mounting block 120 drives the welding torch 130 and the protective cover 140 to return to their initial positions, during the process of aligning the slag discharge port 190 at the bottom of the dust collection box 180 with the slag collection hole 194 on the automatic welding machine 100, the outer end of the push rod 192 abuts against the side of the automatic welding machine 100, causing the push rod 192 to push the baffle 191 to slide against the elastic force of the second spring 193, opening the slag discharge port 190. The welding slag collected in the dust collection box 180 falls into the slag collection hole 194 through the slag discharge port 190, thereby cleaning the welding slag in the dust collection box 180, making it easier to absorb new welding slag when welding again. When welding again, the push rod 192 disengages from the side of the automatic welding machine 100, and the second spring 193 drives the baffle 191 to return to its original position, which can close the slag discharge port 190 again.

[0042] In summary, by using the mounting block 120 to move the welding torch 130, not only is power provided for the scraper 160 to scrape off the welding slag, but also for the rotation of the cleaning brush 170 and the suction of the dust collection box 180. This allows the scraping, cleaning, and collection of welding slag to be completed simultaneously during the welding of the fixed plate. The cleaning of welding slag can be completed during the welding process without the need for an additional power source for slag cleaning or a separate subsequent slag cleaning procedure, thereby effectively improving welding efficiency.
