Description

Technical Field

[0001] This utility model relates to the field of automotive door panel processing technology, specifically a welding fixture for assembling automotive door panels. Background Technology

[0002] Automotive door panel processing refers to a series of manufacturing and processing techniques for automotive door panels. The aim is to process raw materials (such as metal sheets, composite materials, etc.) into automotive door panel components that meet design requirements through processes such as cutting, stamping, welding, grinding, and spraying.

[0003] An existing patent (publication number: CN218836558U) discloses a welding fixture for automobile door panel processing, relating to the field of automobile door panel processing technology. It includes a base plate with slide rails fixedly connected to both sides, and each slide rail has a first groove. This invention, through the setting of a limiting groove, allows a second slider to move within the second groove, driving two limiting rods towards the center, thus detaching the mold from the base plate. Then, a first slider moves within the first groove to adjust to the appropriate position. The extension and retraction of a first electric telescopic rod moves a fixed block and a limiting block, clamping the two limiting rods together. The first slider then moves the limiting block into the limiting groove. Releasing the limiting rods allows the elasticity of the limiting rods to engage with a locking block within the limiting groove. This enables the disassembly and installation of molds of different sizes, expanding the application range of this equipment.

[0004] During use, the aforementioned device can use the elasticity of the limiting rod to engage the locking block on the limiting rod with the limiting groove, thus enabling the disassembly and installation of molds of different sizes and expanding the application range of this equipment. However, during use, because the welding mechanism is completely exposed, the fumes generated during the welding of the door panel will diffuse into the surrounding environment. Furthermore, the device fixes the door panel to the operating table, making it inconvenient to weld the other side of the door panel. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a welding fixture for assembling automobile door panels, which has advantages such as reducing fume diffusion and being able to perform double-sided welding, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for assembling automobile door panels, comprising a body, wherein a fixing and adjusting assembly and a protective assembly are provided on the upper part of the body;

[0007] The fixed adjustment assembly includes a rectangular frame, on the upper surface of which a door panel body is placed. Multiple cylinders are arranged above the rectangular frame, and rubber pads are fixedly connected to the output ends of the multiple cylinders. The multiple rubber pads are in contact with the door panel body. Multiple traction ropes are fixedly connected to the upper surface of the rectangular frame, and multiple limit rods are fixedly connected to the upper surface of the rectangular frame. A swinging component is rotatably connected to the upper end of each limit rod. Multiple cylinders are fixedly connected to the swinging component adjacent to them. Welding components are arranged on both sides of the machine body.

[0008] The protective components include a venting grille, multiple protective curtains hinged to the outer surface of the machine body, the venting grille installed at the top of the machine body, a rectangular frame in contact with the venting grille, a collection frame fixedly connected to the inner wall of the machine body, a T-pipe fixedly connected to the bottom of the collection frame, a filter cartridge fixedly connected to the other end of the T-pipe, two air filters installed inside the filter cartridge, and the other end of the filter cartridge fixedly connected to an external vacuum cleaner. Two scrapers are slidably connected inside the collection frame.

[0009] The above solution, through the combination of cylinder and rubber pad, achieves stable clamping of the door panel body. The rubber pad not only increases the clamping friction, but also effectively protects the door panel surface, preventing scratches or deformation.

[0010] Furthermore, the welding assembly includes two sliding platforms, both of which are slidably connected to the machine body. An electric rotating platform is mounted on the upper surface of each of the two sliding platforms, and a robotic arm is mounted on the upper surface of each of the two electric rotating platforms. A welding device is mounted on the upper end of each of the two robotic arms.

[0011] By using the above solution and setting up welding components, welding can be performed on the other side of the door panel body after the height of the door panel body is adjusted, thereby enabling welding on both sides of the door panel body and further improving the welding efficiency of the door panel body.

[0012] Furthermore, a rotating rod is rotatably connected to the inner wall of the machine body, and the upper ends of the plurality of traction ropes are fixedly connected to the rotating rod. The front end of the rotating rod is fixedly connected to the output end of an external motor.

[0013] The above scheme allows the installation of a rotating rod to rewind the traction rope, enabling the traction rope to pull the rectangular frame and, with the cooperation of the rectangular frame, lift the door panel body. It also works in conjunction with the welding components to weld the other side of the door panel body.

[0014] Furthermore, multiple limiting posts are fixedly connected to the upper surface of the ventilated grid plate, the rectangular frame is slidably connected to the multiple limiting posts, and two contact rods are fixedly connected to the inner wall of the machine body, with each traction rope contacting the contact rod closest to it.

[0015] The above solution allows for the setting of limit posts to limit the rectangular frame, preventing it from swaying during its ascent and enabling the rectangular frame to stably adjust the height of the door panel.

[0016] Furthermore, a cover plate is hinged to the outer surface of the body, and two filter screens are installed at the upper end of the three-way pipe.

[0017] By implementing the above solution, the filter screen can prevent residue in the collection box from entering the three-way pipe, allowing impurities to remain in the collection box, making it easier for the scraper to clean the residue in the collection box and for staff to handle the residue uniformly.

[0018] Furthermore, both robotic arms are equipped with camera modules at their upper ends.

[0019] The above solution enables real-time monitoring of the welding process using a camera module, allowing staff to remotely observe the process and further improving overall automation capabilities.

[0020] Furthermore, a slag discharge trough is provided on the front of the machine body, and a sealing plate is snapped into the inside of the slag discharge trough.

[0021] The above solution allows for easy discharge of residues into the collection frame, while the sealing plate can enclose the collection frame and prevent leakage of smoke entering the collection frame.

[0022] Furthermore, a drive rod is rotatably connected to the inner wall of the machine body. Both ends of the drive rod are provided with threaded grooves, and the two threaded grooves are symmetrical. Both scrapers are threadedly connected to the threaded grooves that are close to each other. The drive rod is fixedly connected to the output end of an external motor.

[0023] The above solution allows two threaded grooves to bring the two scrapers closer together during the rotation of the drive rod, scraping the residue in the collection frame into the groove inside the collection frame. By opening the sealing plate, the impurities in the collection frame can be treated uniformly.

[0024] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0025] This welding fixture for assembling automobile door panels uses a combination of cylinders and rubber pads to achieve stable clamping of the door panel body. The rubber pads not only increase the clamping friction but also effectively protect the door panel surface, preventing scratches or deformation. The cooperation between the limit rod and the swing component further optimizes the position adjustment function of the cylinder, enabling it to adapt to the fixing requirements of door panels of different sizes, enhancing the versatility and flexibility of the equipment. By adjusting the height of the rectangular frame with a traction rope, the door panel can be precisely positioned above the welding device, meeting the processing requirements of door panels of different heights and sizes. The design of the welding components allows welding on both sides of the door panel without flipping the door panel body to weld on the other side, greatly improving welding efficiency. The double-sided welding method improves production efficiency.

[0026] By installing a protective curtain, the spread of fumes during welding is effectively reduced, providing a safer working environment for operators. The combination of the collection frame and the ventilated grid plate can efficiently extract the fumes generated during welding and guide them into the filter cartridge through a three-way pipe. The filter element inside the filter cartridge purifies the fumes, preventing harmful gases and particulate matter from spreading into the surrounding environment and reducing pollution to the working environment. This not only improves the air quality in the workplace but also reduces the harm to the health of operators. The scraper can collect the residue that falls into the collection frame, making it easy to discharge from the machine and preventing impurities from remaining inside the machine.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a welding fixture for assembling automobile door panels includes a body 1, and a fixing and adjusting component 2 and a protective component 3 are provided on the upper part of the body 1.

[0040] Please see Figure 1 , Figure 2 and Figure 3The fixed adjustment assembly 2 includes a rectangular frame 201, on the upper surface of which a door panel body 202 is placed. Multiple cylinders 203 are positioned above the rectangular frame 201, and rubber pads 204 are fixedly connected to the output ends of each cylinder 203. All rubber pads 204 are in contact with the door panel body 202. Multiple traction ropes 205 are fixedly connected to the upper surface of the rectangular frame 201, and multiple limiting rods 206 are fixedly connected to the upper surface of the rectangular frame 201. A swing element 207 is rotatably connected to the upper end of each limiting rod 206. Multiple cylinders 203 are fixedly connected to their adjacent swing elements 207. Welding assemblies 208 are provided on both sides of the machine body 1. Through the combination of the cylinders 203 and the rubber pads 204, the adjustment of the door panel is achieved. The stable clamping of the main body 202, the rubber pad 204 not only increases the clamping friction, but also effectively protects the door panel surface, preventing scratches or deformation. The cooperation between the limit rod 206 and the swing component 207 further optimizes the position adjustment function of the cylinder 203, enabling it to adapt to the fixing requirements of door panels of different sizes, enhancing the versatility and flexibility of the equipment. By adjusting the height of the rectangular frame 201 through the traction rope 205, the door panel can be accurately positioned above the welding device 2084, meeting the processing requirements of door panels of different heights and sizes. The design of the welding component 208 allows welding on both sides of the door panel without flipping the door panel main body 202 to weld on the other side, greatly improving welding efficiency. The double-sided welding method improves production efficiency.

[0041] Please see Figure 1 , Figure 2 and Figure 3 The protective component 3 includes a ventilated grille 301. Multiple protective curtains 302 are hinged to the outer surface of the body 1. The ventilated grille 301 is installed at the upper end of the body 1. A rectangular frame 201 contacts the ventilated grille 301. A collection frame 303 is fixedly connected to the inner wall of the body 1. A three-way pipe 304 is fixedly connected to the bottom end of the collection frame 303. A filter cartridge 305 is fixedly connected to the other end of the three-way pipe 304. Two air filters 306 are installed inside the filter cartridge 305. The other end of the filter cartridge 305 is fixedly connected to an external vacuum cleaner. Two scrapers 307 are slidably connected inside the collection frame 303. By setting the protective curtains 302, the draft is effectively reduced. The diffusion range of fumes during welding provides a safer working environment for operators. The combination of the collection frame 303 and the ventilated grid plate 301 can efficiently extract the fumes generated during welding and guide them into the filter cartridge 305 through the three-way pipe 304. The filter element in the filter cartridge 305 purifies the fumes, preventing harmful gases and particulate matter from spreading into the surrounding environment and reducing pollution to the working environment. This not only improves the air quality in the workplace but also reduces the harm to the health of operators. The scraper 307 can collect the residue that falls into the collection frame 303, making it easy to discharge from the machine body 1 and preventing impurities from accumulating inside the machine body 1.

[0042] Please see Figure 1 , Figure 2 and Figure 3 The welding assembly 208 includes two sliding platforms 2081, both of which are slidably connected to the body 1. An electric rotating platform 2082 is mounted on the upper surface of each sliding platform 2081, and a robotic arm 2083 is mounted on the upper surface of each robotic arm 2083. A welding device 2084 is mounted on the upper end of each robotic arm 2083. By providing the welding assembly 208, welding can be performed on the other side of the door panel body 202 after the height of the door panel body 202 has been adjusted, thereby enabling welding of the door panel body 202. Welding is performed on both sides, further improving the welding efficiency of the door panel body 202. A rotating rod 4 is rotatably connected to the inner wall of the machine body 1. The upper ends of multiple traction ropes 205 are fixedly connected to the rotating rod 4. The front end of the rotating rod 4 is fixedly connected to the output end of an external motor. Installing the rotating rod 4 can wind up the traction ropes 205, so that the traction ropes 205 can pull the rectangular frame 201, and lift the door panel body 202 with the cooperation of the rectangular frame 201. In cooperation with the welding assembly 208, the other side of the door panel body 202 is welded.

[0043] Please see Figure 1 , Figure 2 and Figure 3 Multiple limiting posts 5 are fixedly connected to the upper surface of the ventilation grille 301. The rectangular frame 201 is slidably connected to the multiple limiting posts 5. Two contact rods 6 are fixedly connected to the inner wall of the machine body 1. Each traction rope 205 contacts the contact rod 6 closest to it. The limiting posts 5 can limit the rectangular frame 201 and prevent it from swinging during the upward movement of the rectangular frame 201, so that the rectangular frame 201 can stably adjust the height of the door panel body 202. A cover plate 7 is hinged to the outer surface of the machine body 1. Two filter screens 8 are installed at the upper end of the three-way pipe 304. The filter screens 8 can prevent the residue in the collection frame 303 from entering the three-way pipe 304, so that the impurities can be retained in the collection frame 303, which is convenient for the scraper 307 to clean the residue in the collection frame 303, and facilitates the unified treatment of the residue by the staff.

[0044] Please see Figure 1 , Figure 2 and Figure 4Both robotic arms 2083 are equipped with camera modules 9 at their upper ends. These modules enable real-time monitoring of the welding process, allowing operators to remotely observe the welding operation and further enhancing overall automation. A slag discharge trough 10 is located on the front of the machine body 1. A sealing plate 11 is fitted inside the slag discharge trough 10. The slag discharge trough 10 facilitates the discharge of residue into the collection frame 303, while the sealing plate 11 seals the collection frame 303, preventing the leakage of fumes. The inner wall of 1 is rotatably connected to a drive rod 12. Both ends of the drive rod 12 are provided with threaded grooves 13. The two threaded grooves 13 are symmetrical. The two scrapers 307 are threadedly connected to the threaded grooves 13 that are close to each other. The drive rod 12 is fixedly connected to the output end of an external motor. The two threaded grooves 13 can make the two scrapers 307 approach each other during the rotation of the drive rod 12, scraping the residue in the collection frame 303 into the groove in the collection frame 303. By opening the sealing plate 11, the impurities in the collection frame 303 can be uniformly processed.

[0045] This embodiment provides a welding fixture for assembling automobile door panels. Through the combination of cylinder 203 and rubber pad 204, stable clamping of the door panel body 202 is achieved. The rubber pad 204 not only increases the clamping friction but also effectively protects the door panel surface, preventing scratches or deformation. The cooperation between the limiting rod 206 and the swing element 207 further optimizes the position adjustment function of cylinder 203, enabling it to adapt to the fixing requirements of door panels of different sizes, enhancing the versatility and flexibility of the equipment. By adjusting the height of the rectangular frame 201 through the traction rope 205, the door panel can be precisely positioned above the welding device 2084, meeting the processing requirements of door panels of different heights and sizes. The design of the welding assembly 208 allows welding on both sides of the door panel without flipping the door panel body 202 to weld on the other side, significantly improving welding efficiency. The double-sided welding method improves production efficiency.

[0046] By setting up the protective curtain 302, the diffusion range of fumes during welding is effectively reduced, providing a safer working environment for operators. The combination of the collection frame 303 and the ventilated grid plate 301 can efficiently extract the fumes generated during welding and guide them into the filter cartridge 305 through the three-way pipe 304. The filter element in the filter cartridge 305 purifies the fumes, preventing harmful gases and particulate matter from spreading into the surrounding environment and reducing pollution to the working environment. This not only improves the air quality in the workplace but also reduces the harm to the health of operators. The scraper 307 can collect the residue that falls into the collection frame 303, making it easy to discharge from the machine body 1 and preventing impurities from accumulating inside the machine body 1.

[0047] The working principle of the above embodiment is as follows: First, the door panel body 202 is placed on the rectangular frame 201. Then, the position of the cylinder 203 is adjusted by the cooperation of the swing member 207 and the limiting rod 206, so that the cylinder 203 is located at the corner of the door panel body 202. At this time, the cylinder 203 pushes the rubber pad 204 to contact the door panel body 202, thereby clamping the door panel body 202. Then, the two sliding platforms 2081 are slid, so that the two robotic arms 2083 are in the welding position. Then, the robotic arms 2083 swing downward and weld the door panel through the welding device 2084. Welding work is carried out at the welding position of the main body 202. During the welding process, the generated fumes are isolated inside the main body 1 by the protective curtain 302. At this time, the external vacuum cleaner transmits suction power through the filter cartridge 305 to the three-way pipe 304, so that the three-way pipe 304 can draw the fumes inside the main body 1 into the filter cartridge 305, thereby filtering the welding fumes by the air filter 306. The residue generated during welding passes through the vent grille 301 and enters the collection frame 303. After one side of the door panel main body 202 is welded, the external motor drives the rotation. The rotation of lever 4 allows it to wind up the traction rope 205, enabling the traction rope 205 to pull the rectangular frame 201, which in turn raises the rectangular frame 201 within the machine body 1. This positions the door panel body 202 above the welding assembly 208. Subsequently, the robotic arm 2083 swings upward and performs welding work on the other side of the door panel body 202 via the welding device 2084. This eliminates the need to flip the door panel body 202 to weld the other side, significantly improving welding efficiency. The double-sided welding method enhances production efficiency. During the welding process, the camera module... Block 9 can monitor the welding process in real time, allowing staff to observe the welding process remotely, further improving the overall automation capability. After welding is completed, the external motor drives the drive rod 12 to rotate, so that the drive rod 12 can move the two scrapers 307 closer to each other through the cooperation of the threaded groove 13 during the rotation, and scrape the impurities in the collection frame 303 into the groove in the collection frame 303. The staff can open the sealing plate 11 and remove the residue in the collection frame 303 through the slag discharge groove 10, avoiding the impurities from being retained in the machine body 1.
