Description

Technical Field

[0001] This invention relates to the field of transposition device technology, specifically to a transposition device for stamping plates in a stamping and welding production line. Background Technology

[0002] The stamping sheet changing device in the stamping and welding production line is mainly used in the automated conveying link between the stamping and welding processes in the automobile manufacturing and large sheet metal processing industries. As a key hub connecting the front and rear processes, it undertakes the important task of grabbing, flipping, adjusting the height of the formed metal sheet and accurately transferring it to the welding station. At the technical level, this device has had a significant innovative and optimizing impact on the existing technology.

[0003] However, when using existing positioning devices, it is difficult to adjust them according to the actual shape of irregularly shaped stamping plates with protrusions, depressions or complex curvatures on the surface. As a result, the clamping parts and the plate can only form local point contact or line contact, and the contact area is extremely limited. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping plate changing device for a stamping and welding production line. By setting up a clamping part, it solves the problem that existing changing devices are difficult to adjust according to the actual shape of irregularly shaped stamping plates with protrusions, depressions or complex curvatures on the surface during use, resulting in only local point contact or line contact between the clamping part and the plate, and the contact area is extremely limited.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a stamping plate changing device for a stamping and welding production line. It includes two fixed plates and several self-braking casters positioned below the two fixed plates. The device further includes: a clamping part disposed on the two fixed plates; a rotating part mounted on the right-side fixed plate; two lifting parts respectively disposed on the two fixed plates; each clamping part includes two adapter components disposed between the two fixed plates; and a sliding component disposed between the two fixed plates. Each adapter component includes a fixed rod disposed between the two fixed plates. A connecting block is fixedly connected to the left side of the fixed rod. Two arc-shaped grooves are formed on the connecting block, and arc-shaped sliding rods are slidably connected within each of the two arc-shaped grooves. Connecting blocks are fixedly connected to the inner walls of each of the two arc-shaped sliding rods, and two arc-shaped grooves are formed on each of the two connecting blocks. Each of the arc-shaped grooves contains an adapter component, and the two adapter components are mirror-image positioned.

[0006] Furthermore, the rotating part includes a rotating assembly mounted on a fixed plate located on the right side; and a transmission assembly disposed on the fixed plate located on the right side. The rotating part is used to flip the clamping part.

[0007] Furthermore, the lifting part includes a hinge assembly disposed below the two fixed plates; and a drive assembly mounted on the hinge assembly, the drive assembly being used to drive the hinge assembly.

[0008] Furthermore, the sliding assembly includes two connecting rods rotatably connected to two fixed plates. The connecting rod on the right side passes through the fixed plate on the right side. A fixed shell is fixedly connected to the outer wall of the two connecting rods. Two sliders are provided on the inner wall of the fixed shell. A sliding groove is provided on the fixed shell. The two sliders are slidably connected in the sliding groove. A bidirectional threaded rod passes through the two sliders. The bidirectional threaded rod is threadedly connected to the two sliders. A motor is fixedly connected to the inner wall of the fixed shell. The output shaft of the motor is fixedly connected to the bidirectional threaded rod through a coupling. The two fixed rods are fixedly connected to the two sliders respectively.

[0009] Furthermore, the rotating assembly includes two fixed plates 1 fixedly connected to the right fixed plate, and a rotating shaft rotatably connected between the two fixed plates 1. The top of the rotating shaft passes through the upper fixed plate 1. A motor 2 is fixedly connected to the top of the upper fixed plate 1. The output shaft of the motor 2 is fixedly connected to the rotating shaft through a coupling. The motor 2 is fixedly connected to the upper fixed plate 1 through a motor bracket.

[0010] Furthermore, the transmission assembly includes a worm gear fixedly connected to the outer wall of the rotating shaft, and a worm wheel fixedly connected to the outer wall of the connecting rod. The worm gear meshes with the worm wheel, and the worm wheel and worm gear have an anti-reverse rotation effect during transmission.

[0011] Furthermore, the hinge assembly includes a second fixed plate disposed below the fixed plate. A hinge block is fixedly connected to the side of the second fixed plate that is close to the fixed plate. A hinge rod is hinged to the side of the two hinge blocks that are close to each other. The two hinge rods are hinged together. A slide rail is fixedly connected to the side of the second fixed plate that is close to the fixed plate. The side of the two hinge rods that is away from the hinge block is slidably connected to the two second fixed plates respectively. Several universal wheels with built-in brakes are fixedly connected to the two second fixed plates respectively.

[0012] Furthermore, the drive assembly includes a second groove formed on a fixed plate and a lower fixed plate, a second connecting rod slidably connected in the second groove, a third fixed plate fixedly connected to the bottom of the second fixed plate, an electric telescopic rod fixedly connected to the rear side of the third fixed plate, the output end of the electric telescopic rod being fixedly connected to the second connecting rod, and the second connecting rod being hinged to a corresponding hinge rod.

[0013] The present invention has the following beneficial effects: 1. This invention, by setting up a clamping part, uses a motor to drive a bidirectional threaded rod to rotate, causing two sliders to approach each other within a groove. Then, a connecting rod pushes a fixed rod towards the stamping plate. As the fixed rod approaches the plate, the connecting block three first contacts the plate. When there are protrusions or depressions on the plate surface, the connecting block three drives the arc-shaped sliding rod two to slide within the arc-shaped groove two, while the connecting block two drives the arc-shaped sliding rod one to slide within the arc-shaped groove one. This allows the connecting block three to adaptively adjust according to the surface shape of the plate, improving the clamping stability and reliability for irregularly shaped or complex curved plates. It also effectively prevents damage to the plate surface or slippage during repositioning due to insufficient contact area, thereby improving overall production quality and safety.

[0014] 2. This invention, by setting up a rotating part, after clamping the stamping plate, starts motor two, drives the rotating shaft to rotate on fixed plate one, and then drives the worm gear to rotate. Utilizing the meshing transmission principle of worm gear, the rotational motion of the worm gear is converted into the rotation of connecting rod one on the fixed plate. Connecting rod one then drives the fixed shell and its internal clamping mechanism to rotate synchronously, ultimately realizing a 180-degree flipping action of the stamping plate. This effectively prevents reversal caused by the plate's own weight or external force, significantly improves the locking stability and safety of the position during the flipping process, and achieves stable reversal of the plate, facilitating subsequent welding processes.

[0015] 3. This invention, by setting up a lifting section, after completing the flipping action, activates the electric telescopic rod on the fixed plate three to extend after the flipping action is completed, in order to adapt to the height requirements of different processing devices. The electric telescopic rod pushes the connecting rod two to slide in the slide groove two, thereby driving the hinge rod to move on the slide rail. Since the two hinge rods are cross-hinged, their sliding causes the included angle between the two rods to decrease, thereby driving the top fixed plate one and its clamping mechanism to achieve vertical height adjustment. This not only effectively improves the versatility and compatibility of the device, enabling it to seamlessly connect with stamping or welding equipment of different heights, but also provides extremely high support stability and load-bearing capacity through the scissor structure, ensuring the stability and safety of the material plate during the lifting process, and avoiding production interruptions or workpiece collisions caused by equipment height mismatch.

[0021] Please see Figures 1-8 As shown, the present invention is a stamping plate changing device for a stamping and welding production line, including two fixed plates 111 and a plurality of universal wheels 112 with built-in brakes disposed below the two fixed plates 111. It also includes: a clamping part 2 disposed on the two fixed plates 111; a rotating part 3 mounted on the fixed plate 111 located on the right side; and two lifting parts 4 disposed on the two fixed plates 111 respectively. The clamping part 2 includes an adapter component 21, of which two are provided, each disposed between two fixed plates 111; and a sliding component 22, which is installed between the two fixed plates 111. Each adapter component 21 includes a fixed rod 211 disposed between the two fixed plates 111. A connecting block 212 is fixedly connected to the left side of the fixed rod 211. Two arc-shaped grooves 213 are formed on the connecting block 212, and arc-shaped sliding rods 214 are slidably connected within each of the two arc-shaped sliding rods 214. Connecting blocks 215 are fixedly connected to the inner walls of each of the two arc-shaped sliding rods 214, and two arc-shaped grooves 216 are formed on each of the two connecting blocks 215. Adapter parts are disposed within each of the arc-shaped grooves 216. The two adapter components 21 are mirror images of each other. The sliding component 22 includes two connecting rods 221 rotatably connected to the two fixed plates 111, located on the right side. Connecting rod 221 passes through the fixed plate 111 on the right side. The outer walls of the two connecting rods 221 are fixedly connected to the fixed shell 222. The inner wall of the fixed shell 222 is provided with two sliders 223. The fixed shell 222 has a groove 224. The two sliders 223 are slidably connected in the groove 224.

The two fixed rods 211 are fixedly connected to the two sliders 223 respectively. By setting the clamping part 2, not only is the clamping stability and reliability of irregular or complex curved material plates improved, but also the surface damage of the material plate or slippage during the repositioning process caused by the small contact area is effectively prevented, thereby improving the overall production quality and safety.

[0022] The rotating part 3 includes a rotating assembly 31, which is mounted on a fixed plate 111 located on the right side; and a transmission assembly 32, which is also mounted on the fixed plate 111 located on the right side. The rotating part 3 is used to flip the clamping part 2. The rotating assembly 31 includes two fixed plates 311 fixedly connected to the fixed plate 111 located on the right side. A rotating shaft 312 is rotatably connected between the two fixed plates 311. The top of the rotating shaft 312 passes through the upper fixed plate 311. A motor 313 is fixedly connected to the top of the upper fixed plate 311. The output shaft of the motor 313 is connected to the upper fixed plate 311 via a coupling. The rotating shaft 312 is fixedly connected, and the second motor 313 is fixedly connected to the fixed plate 311 located above it through the motor bracket. The transmission component 32 includes a worm 321 fixedly connected to the outer wall of the rotating shaft 312. A worm wheel 322 is fixedly connected to the outer wall of the connecting rod 221. The worm 321 and the worm wheel 322 mesh with each other. The worm wheel 322 and the worm 321 have an anti-reverse effect during transmission. By setting the rotating part 3, the reverse rotation caused by the weight of the material plate or external force can be effectively prevented, which significantly improves the stability and safety of the locking position during the flipping process, realizes the stable reversal of the material plate, and facilitates the subsequent welding process.

[0023] The lifting part 4 includes a hinge assembly 41, which is disposed below two fixed plates 111; and a drive assembly 42, which is mounted on the hinge assembly 41 and is used to drive the hinge assembly 41. The hinge assembly 41 includes a second fixed plate 411 disposed below the fixed plate 111. Hinges 412 are fixedly connected to the sides of the second fixed plate 411 that are close to the fixed plate 111. Hinges 413 are hinged to the sides of the two hinge blocks 412 that are close to each other. The two hinge rods 413 are hinged together. Slide rails 414 are fixedly connected to the sides of the second fixed plate 411 that are close to the fixed plate 111. The sides of the two hinge rods 413 away from the hinge blocks 412 are respectively connected to the two fixed plates 411. 11. A sliding connection is provided, with several universal wheels 112 with built-in brakes fixedly connected to two fixed plates 411. The drive assembly 42 includes a groove 421 opened on the fixed plate 111 and the lower fixed plate 411. A connecting rod 422 is slidably connected in the groove 421. A fixed plate 423 is fixedly connected to the bottom of the fixed plate 411. An electric telescopic rod 424 is fixedly connected to the rear side of the fixed plate 423. The output end of the electric telescopic rod 424 is fixedly connected to the connecting rod 422. The connecting rod 422 is hinged to the corresponding hinge rod 413. By setting the lifting part 4, the stability and safety of the material plate during the lifting process are ensured, and production interruption or workpiece collision caused by mismatch in equipment height is avoided.

[0024] In use, the stamping plate is placed between the two fixed rods 211, and then the motor 226 is started. When the motor 226 rotates, the bidirectional threaded rod 225 will bring the two sliders 223 closer to each other. When the two sliders 223 move, they will slide in the slide groove 224. As the two sliders 223 approach each other, the two connecting rods 221 will be brought closer to the stamping plate by the sliders 223. As the fixed rods 211 approach the stamping plate, the connecting block 218 will first contact the stamping plate. When there is a protrusion or depression on the stamping plate, the connecting block 218 will bring the arc-shaped sliding rod 217 to slide in the arc-shaped slide groove 216, while the connecting block 215 will bring the arc-shaped sliding rod 214 to slide in the arc-shaped slide groove 213. This allows the connecting block 218 to fit completely with the stamping plate, thereby increasing the contact area between the connecting block 218 and the stamping plate. After clamping is completed, start motor 2 313. When motor 2 313 rotates, it will drive shaft 312 to rotate on fixed plate 1 311. When shaft 312 rotates, it will drive worm 321 to rotate. As worm 321 rotates, it will drive connecting rod 1 221 to rotate on fixed plate 111 through worm wheel 322. When connecting rod 1 221 rotates, it will drive fixed shell 222 to rotate as well. When fixed shell 222 rotates, stamping plate will also move. After connecting rod 1 221 rotates to 180 degrees, it can be flipped. After flipping, the height of the stamping plate can be adjusted to adapt to the height of different processing devices. During adjustment, the electric telescopic rod 424 on the fixed plate 3 423 can be activated to extend it backward. When the electric telescopic rod 424 extends, the connecting rod 2 422 will slide in the slide groove 2 421. When the connecting rod 2 422 slides, the corresponding hinge rod 413 will slide on the slide rail 414. Since the two hinge rods 413 are hinged, the included angle between the two hinge rods 413 will decrease when sliding, and the extension distance will also decrease. Thus, the effect of adapting to different processing devices by adjusting the height of the fixed plate 111 can be achieved.
