Description

Technical Field

[0001] This invention relates to the field of automated welding equipment technology, specifically to an automated welding device for processing automotive parts. Background Technology

[0002] Welding is a core process in the manufacturing of automotive mufflers and exhaust pipes. As key components of the automotive exhaust system, the welding quality of these components directly affects exhaust noise reduction, sealing performance, and service life. Automotive mufflers and exhaust pipes are mostly made of metals such as stainless steel and aluminum alloys, requiring reliable welding to achieve sealed connections and structural reinforcement. Resistance welding and arc welding are widely used in their production. With increasingly stringent automotive emission regulations and higher product reliability requirements, the welding precision and sealing performance requirements for mufflers and exhaust pipes are constantly increasing. Automated welding has become crucial for the large-scale production of these components. Utilizing technologies such as welding robots and intelligent sensors, precise control and efficient operation of the welding process can be achieved, meeting the core requirements of automotive muffler and exhaust pipe manufacturing for connection strength, sealing performance, and production efficiency.

[0003] Authorization announcement number CN119387996B discloses a welding device for welding automotive parts. This invention relates to the field of welding equipment technology, including a worktable, a clamping mechanism, and a welding mechanism. The welding mechanism includes two C-shaped plates and two welding torches. A C-shaped annular groove and a C-shaped guide groove are coaxially arranged on the first side of the C-shaped plates. A conveyor belt and a drive assembly are disposed within the C-shaped annular groove. The C-shaped guide groove is located outside the C-shaped annular groove. A sliding column is slidably connected within the C-shaped guide groove. The welding torch is rotatably engaged with the sliding column and is slidably engaged with and elastically connected to the sliding column. A drive column is slidably connected to the welding torch along its extension direction. The drive column is rotatably engaged with the welding torch and fixedly connected to the conveyor belt. The conveyor belt drives the drive column to move along the C-shaped annular groove, and the drive column drives the welding torch and the sliding column to move along the C-shaped guide groove. This welding device for welding automotive parts is suitable for welding double-row pipes, and the welding torch can achieve continuous circumferential welding, improving welding efficiency and weld quality. The aforementioned invention uses a conveyor belt to drive a drive column to move along a C-shaped groove. The drive column drives the welding gun and slide column 81 to move along a C-shaped guide groove. When the slide column moves to the second end of the C-shaped guide groove, the slide column stops moving. The drive column continues to move under the drive of the conveyor belt. The drive column can drive the welding head of the welding gun to the starting position through the cooperation of the components, thereby realizing continuous circumferential welding between the automobile exhaust pipe and the muffler. Furthermore, the center of the C-shaped plate needs to be aligned with the center of the exhaust pipe through the cooperation of the mounting arm, electric telescopic cylinder one, mounting plate, electric telescopic cylinder two, mounting block, and connecting rod. However, in the actual welding process described in the above patent, when the welding torch moves to the side of the second end of the C-shaped guide groove, the sliding column needs to change direction through the cooperation of the components to return the welding torch to the initial position. Thus, the welding torch needs to pause its movement. During this process, the welding torch will continue to weld at a fixed position. As a result, welding time at a certain position is too long, which not only affects the aesthetics but also has a certain impact on the welding quality. If the welding torch is turned off, the weld will cool down, and restarting the welding torch will also affect the welding quality. The C-shaped plate needs to be aligned with the center of the exhaust pipe through the displacement and rotation of the components. The process is relatively complex and can easily cause center deviation. When the chuck clamps and fixes the exhaust pipe, it can easily cause the welding position of the exhaust pipe and the muffler to shift, affecting the welding accuracy. Summary of the Invention

The ends of the first arc-shaped rotating plate and the second arc-shaped rotating plate can be connected by the cooperation of parts to continue rotating on the inner walls of the first arc-shaped mounting plate and the second arc-shaped mounting plate.

The two first gears are respectively mounted on the surfaces of the first arc-shaped mounting plate and the second arc-shaped mounting plate through the second driving component. The outer surfaces of the adjacent ends of the first and second arc-shaped mounting plates are provided with second gears that cooperate with tooth grooves through the through arc-shaped grooves.

[0009] Preferably, the ring welding assembly further includes a second mounting bracket and a first hinge point, and the second mounting bracket is fixedly installed on the inner wall of the top end of the first arc-shaped rotating plate and the inner wall of the bottom end of the second arc-shaped rotating plate.

[0010] Preferably, the ring welding assembly further includes a second cylinder and a second hinge point. The second cylinder is fixedly mounted on the second mounting bracket, and the output end of the second cylinder is equipped with the second hinge point. The second hinge point is slidably mounted on the outer surface of the welding head via a sliding member.

[0011] Preferably, the ring welding assembly further includes a mating groove and a locking member. Both ends of the first arc-shaped mounting plate and the second arc-shaped mounting plate are provided with mating grooves.

The two ends of the elastic element II are respectively fixedly installed on the limiting plate and the moving rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the automated welding device for processing automotive parts; 1. The device is equipped with a first arc-shaped rotating plate and a second arc-shaped rotating plate, which can drive the welding head to rotate along the inner wall of the first arc-shaped mounting plate and the second arc-shaped mounting plate through the cooperation of the components. When the welding head rotates, it can weld the connection between the muffler and the exhaust pipe. When one end of the first arc-shaped rotating plate and the second arc-shaped rotating plate rotates from one end of the first arc-shaped mounting plate to the other end, the ends of the first arc-shaped rotating plate and the second arc-shaped rotating plate can be connected through the cooperation of the components to continue rotating on the inner wall of the first arc-shaped mounting plate and the second arc-shaped mounting plate. When the welding head rotates to the initial position, it can achieve 360° continuous welding, maintaining the aesthetics and strength of the weld after welding. 2. When the third cylinder is working, the output end will push the two fixed rods closer to the exhaust pipe surface. When the fixed rods move, they can drive the mounting cover and sliding ball closer to the exhaust pipe surface. When the sliding ball moves to the exhaust pipe surface, it will squeeze the exhaust pipe. Since the exhaust pipe has been squeezed and fixed by the second clamping member, the squeezing force of the sliding ball will be transmitted to the first arc-shaped rotating plate and the second arc-shaped rotating plate, and then transmitted to the first arc-shaped mounting plate and the second arc-shaped mounting plate. The first arc-shaped mounting plate and the second arc-shaped mounting plate can adjust their own center to be on the same straight line as the center of the exhaust pipe through the cooperation of the parts. The center alignment operation is convenient, which greatly improves the welding accuracy of the welding head and can be adapted to exhaust pipes of various sizes. 3. When the exhaust pipe is a single unit, the opposing moving parts can drive the first arc-shaped mounting plate and the second arc-shaped mounting plate to move through the cooperation of the components. When the first arc-shaped mounting plate and the second arc-shaped mounting plate move towards each other, their ends will be inserted into the corresponding mating grooves and fixed by the locking parts, thus forming a complete circle. At this time, the first arc-shaped rotating plate and the second arc-shaped rotating plate can rotate simultaneously through the operation of the components. When the first arc-shaped rotating plate and the second arc-shaped rotating plate rotate, they will drive the two welding heads to weld. When the two welding heads rotate 180°, the welding work can be completed, which can greatly improve the working efficiency of welding a single exhaust pipe. 4. The first and second arc-shaped rotating plates are configured to rotate, which will drive the track groove to rotate. The track groove can slide along the outer surface of the slide rail when it rotates, which can improve the stability of the first and second arc-shaped rotating plates when they rotate. 5. When the welding head moves to the designated position, the second cylinder can push the second hinge point downward. When the second hinge point moves downward, it can push the slider to slide in the slide groove. While the slider slides, it will push the welding head to rotate. When the welding head rotates, the first hinge point and the second mounting bracket can rotate. When the welding head rotates to the designated angle, it can weld the connection between the muffler and the exhaust pipe, improving the stability of the welding head and the weld.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; 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, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0019] Please see Figure 1 The present invention provides an embodiment of an automated welding device for processing automotive parts, comprising: a processing platform 100, on which a first clamping member 210 and a second clamping member 220 for clamping a muffler and an exhaust pipe are mounted. The first clamping member 210 and the second clamping member 220 are mature products on the market and are therefore not described in detail. A welding mechanism 300 for welding the connection between the muffler and the exhaust pipe is mounted on the processing platform 100. The welding mechanism 300 includes a displacement component, a ring welding component, and a position correction component. It should be noted that before welding, the muffler and exhaust pipe need to be fixed on the first clamping member 210 and the second clamping member 220 respectively, and the end of the exhaust pipe to be welded should be aligned with the position of the muffler to be welded. After the muffler and exhaust pipe are fixed, the ring welding assembly and the position correction assembly can be moved to the side of the exhaust pipe by the displacement assembly on the welding mechanism 300. When the ring welding assembly and the position correction assembly are moved to the designated position, the position correction assembly can adjust the center of the ring welding assembly and the center of the exhaust pipe to the designated position. At this time, the ring welding assembly can perform 360° ring welding on the exhaust pipe.

[0020] like Figures 1-4 As shown, the displacement assembly includes a transverse moving part 311 and an opposing moving part 316. A set of transverse moving parts 311 is symmetrically installed in the front and back directions along the length of the processing platform 100. The transverse moving part 311 can be composed of a motor, a bearing seat, a lead screw, and other components. The two sets of transverse moving parts 311 are connected by a moving frame 312. A first cylinder 313 is fixedly installed at the center of the top of the moving frame 312 by bolts. An opposing moving part 316 is provided at the bottom of the first cylinder 313. The opposing moving part 316 is generally composed of a fixed plate, a two-way lead screw, a motor, and an internal threaded slider. Two moving rods 317 are symmetrically installed at the center of the bottom of the opposing moving part 316. It is conceivable that when the first motor operates, it drives the lead screw to rotate on the bearing seat. When the lead screw rotates, it drives the moving frame 312 to move horizontally along the length of the processing platform 100. When the moving frame 312 moves, it can drive the ring welding assembly and the position correction assembly to the position to be welded through related components. At this time, the first cylinder 313 operates and can drive the ring welding assembly and the position correction assembly to the side of the exhaust pipe through the cooperation of components. When the ring welding assembly and the position correction assembly move to the side of the exhaust pipe, the second motor operates and drives the bidirectional lead screw to rotate on the fixed plate. When the bidirectional lead screw rotates, it can drive the two internal thread sliders to move towards each other. The two internal thread sliders moving towards each other can drive the two moving rods 317 to move towards each other. When the two moving rods 317 move towards each other, they can drive the ring welding assembly and the position correction assembly to the corresponding position.

[0021] like Figures 1-3 As shown, the displacement assembly also includes a first mounting bracket 314 and a rotating bracket 315. The output end of the first cylinder 313 is fixedly mounted on the first mounting bracket 314. A driving component 1 is fixedly mounted on the inner side of the first mounting bracket 314. The driving component 1 can be a motor 3. The output end of the driving component 1 is fixedly mounted on the rotating bracket 315. The bottom of the rotating bracket 315 is fixedly mounted at the top center of the opposing moving component 316. It is worth noting that after one end of the muffler is welded to the exhaust pipe, the position correction component loosens the exhaust pipe and moves the position correction component and the ring welding component out of the side of the exhaust pipe through the operation of the opposing moving part 316. At this time, the operation of the first cylinder 313 will drive the opposing moving part 316, the position correction component and the ring welding component to move to the designated height. The operation of the lateral moving part 311 will drive the position correction component and the ring welding component to the other end of the muffler where welding is required. The operation of the motor 3 will drive the rotating frame 315 to rotate. When the rotating frame 315 rotates, it can drive the lateral moving part 311 to rotate. When the lateral moving part 311 rotates, it can drive the position correction component and the ring welding component to change the welding direction. After the ring welding component changes direction, the other end of the muffler and the exhaust pipe can continue to be ring welded.

[0022] like Figures 2-7 As shown, the ring welding assembly includes a first arc-shaped mounting plate 321 and a second arc-shaped mounting plate 322. The first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 are symmetrically arranged on one side of the two moving rods 317. The first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 are slidably installed on the inner side of the first arc-shaped mounting plate 321 and the second arc-shaped rotating plate 3216 respectively. The first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 are each provided with a rotatable welding head 3213 at opposite ends. The welding head 3213 can rotate 360° within the first arc-shaped mounting plate 321 or the second arc-shaped mounting plate 322 through the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216, so that the welding head 3213 can perform ring welding on the exhaust pipe and the muffler. It is clear that the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 can be aligned with the center of the exhaust pipe through the cooperation of the opposing moving part 316 and the position correction component. After the positions of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 are adjusted, the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 can rotate on the inner walls of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 through the cooperation of the components. When the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 rotate, they can drive the welding head 3213 to rotate. When the welding head 3213 rotates, it can weld the connection between the muffler and the exhaust pipe. When one end of the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 rotates from one end of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 to the other end, the ends of the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 can be connected by the cooperation of the parts and continue to rotate on the inner wall of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322. When the welding head 3213 rotates to the initial position, it can achieve 360° continuous welding, maintaining the aesthetics and strength of the weld after welding.

[0023] like Figures 2-6 As shown, the ring welding assembly also includes a track groove 325 and a slide rail 326. The inner sides of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 are both fixedly mounted with slide rails 326. The outer surfaces of the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 are both provided with track grooves 325 that cooperate with slide rails 326. It should be understood that when the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 rotate, they will drive the track groove 325 to rotate. When the track groove 325 rotates, it can slide along the outer surface of the slide rail 326, thereby improving the stability of the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 when rotating.

[0024] like Figures 2-7 As shown, the ring welding assembly also includes a toothed groove 327, a first gear 328, and a second gear 329. The outer surfaces of the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 are both provided with toothed grooves 327. The outer surfaces of the top ends of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 are provided with first gears 328 that cooperate with toothed grooves 327 through through arc-shaped grooves. The two first gears 328 are respectively mounted on the surfaces of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 through driving component two. The outer surfaces of the ends of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 are respectively provided with second gears 329 that cooperate with toothed grooves 327 through through arc-shaped grooves. The two second gears 329 are respectively mounted on the surfaces of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 through driving component three. Driving component two and driving component three are generally composed of components such as motor four, pulley, belt, rotating rod, and bearing seat. It should be noted that during welding, the second driving component on the first arc-shaped mounting plate 321 and the third driving component on the second arc-shaped mounting plate 322 work simultaneously. When the second and third driving components work, they can drive the first gear 328 and the second gear 329 to rotate respectively through the components. When the first gear 328 and the second gear 329 rotate, they can drive the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 to rotate in opposite directions through the tooth groove 327. When the ends of the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 rotate to the first arc-shaped mounting plate 321... When the inner wall of the top of the 21st arc-shaped mounting plate 322 is aligned with the inner wall of the end of the second arc-shaped mounting plate 322, the ends of the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 will mesh with the first gear 328 and the second gear 329 through the tooth groove 327. At this time, the second driving component on the first arc-shaped mounting plate 321 stops working and the third driving component starts working, while the third driving component on the second arc-shaped mounting plate 322 stops working and the second driving component starts working. When the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 rotate 360°, the welding head 3213 can perform circumferential welding on the exhaust pipe and the muffler.

[0025] like Figures 4-7 As shown, the ring welding assembly also includes a second mounting bracket 3211 and a first hinge point 3212. The second mounting bracket 3211 is fixedly installed on the inner wall of the top of the first arc-shaped rotating plate 324 and the inner wall of the bottom of the second arc-shaped rotating plate 3216. The two adjacent sides of the second mounting brackets 3211 are rotatably connected to the welding head 3213 through the first hinge point 3212. The ring welding assembly also includes a second cylinder 3214 and a second hinge point 3215. The second cylinder 3214 is fixedly installed on the second mounting bracket 3211. The output end of the second cylinder 3214 is installed with the second hinge point 3215. The second hinge point 3215 is slidably installed on the outer surface of the welding head 3213 through a sliding member. The sliding member is generally composed of components such as a slider and a groove. It is worth noting that when the welding head 3213 moves to the designated position, the second cylinder 3214 can push the second hinge point 3215 downward when it works. When the second hinge point 3215 moves downward, it can push the slider to slide in the groove. While the slider slides, it will push the welding head 3213 to rotate. When the welding head 3213 rotates, it can rotate through the first hinge point 3212 and the second mounting bracket 3211. When the welding head 3213 rotates to the designated angle, it can weld the connection between the muffler and the exhaust pipe.

[0026] like Figures 2-7As shown, the ring welding assembly also includes a mating groove 323 and a locking member 3210. Both ends of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 are provided with mating grooves 323. The mating grooves 323 on the first arc-shaped mounting plate 321 and the mating grooves 323 on the second arc-shaped mounting plate 322 are staggered. The locking member 3210 is installed inside the mating groove 323. The locking member 3210 is generally composed of components such as insert plates, slots, bolts and nuts. It is clear that when the exhaust pipe is a single pipe, the operation of the opposing moving part 316 can drive the two moving rods 317 to move towards each other. When the two moving rods 317 move towards each other, the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 can be moved by the cooperation of the parts. When the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 move towards each other, their ends will be inserted into the corresponding mating grooves 323 respectively. At the same time, the insert plate and the bolt can be inserted into the slot. After the side of the bolt is inserted into the slot, the nut can be tightened. When the nut is tightened, the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 can be fixed together. After the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 are fixed, the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 can rotate simultaneously through the operation of the components. When the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 rotate, they will drive the two welding heads 3213 to perform welding. When the two welding heads 3213 rotate 180°, the welding work can be completed, which can greatly improve the working efficiency of welding a single exhaust pipe.

[0027] like Figures 2-7 As shown, the position correction assembly includes a fixed frame 331 and a sliding ball 335. Two fixed frames 331 are symmetrically fixedly installed on the sides of the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216. A third cylinder 332 is fixedly installed inside each fixed frame 331. Two fixed rods 333 facing opposite directions are symmetrically fixedly installed on the output end of the third cylinder 332. A mounting cover 334 is installed on the other end of the fixed rods 333. A sliding ball 335 is movably installed inside the mounting cover 334. It should be understood that when the third cylinder 332 is working, the output end will push the two fixed rods 333 closer to the exhaust pipe surface. When the fixed rods 333 move, they can drive the mounting cover 334 and the sliding ball 335 closer to the exhaust pipe surface. When the sliding ball 335 moves to the exhaust pipe surface, it will squeeze the exhaust pipe. Since the exhaust pipe has been squeezed and fixed by the second clamping member 220, the squeezing force of the sliding ball 335 will be transmitted to the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216, and then transmitted from the first arc-shaped rotating plate 324 and the second arc-shaped rotating plate 3216 to the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322. The first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 can adjust their own center to be on the same straight line as the center of the exhaust pipe through the cooperation of the parts, thereby improving the welding accuracy of the welding head 3213.

[0028] like Figures 2-6 As shown, the position correction assembly also includes a sliding cover 336 and a moving block 337. The sliding cover 336 is slidably installed on the outer surface of the two moving rods 317. The moving block 337 is movably installed inside the moving rods 317 through a sliding cavity. The moving block 337 is fixedly connected to the sliding cover 336. The bottom end of the moving block 337 is connected to the bottom of the sliding cavity of the moving rod 317 through an elastic element. The elastic element can be composed of springs or other components. The position correction assembly also includes a guide rod 338 and a limiting plate 339. The guide rod 338 is slidably installed inside the sliding cover 336 and the moving block 337 through a sliding hole. One adjacent end of the two guide rods 338 is fixedly installed on the surface of the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322, respectively. The other end of the two guide rods 338 is fixedly installed on the limiting plate 339. The outer surface of the two guide rods 338 is sleeved with an elastic element. The elastic element can be composed of springs or other components. The two ends of the elastic element are fixedly installed on the limiting plate 339 and the moving rod 317, respectively. It should be noted that when the sliding ball 335 transmits the compressive force to the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322, and when the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 are in the lateral adjustment position, the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 will push the guide rod 338 to move laterally. When the guide rod 338 moves laterally, it can slide inside the sliding hole of the sliding cover 336 and the moving block 337. When the guide rod 338 slides, it will drive the limiting plate 339 to move. When in motion, the second spring can be compressed and stretched. When the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 are in the vertical adjustment position, the first arc-shaped mounting plate 321 and the second arc-shaped mounting plate 322 will drive the guide rod 338 to move vertically. When the guide rod 338 moves vertically, it can drive the sliding cover 336 to slide along the surface of the moving rod 317. While the sliding cover 336 slides, it will drive the moving block 337 to slide inside the sliding cavity of the moving rod 317. While the moving block 337 slides, it will extend and retract the first spring.
