Description

Technical Field

[0001] The present invention relates to the technical field of welding tooling, and particularly to an automatic welding tooling for a muffler. Background Art

[0002] The automatic welding tooling for a muffler is mainly used for welding operations in the production process of mufflers. Through automatic equipment and precise tooling design, it improves welding efficiency, ensures welding quality, reduces errors in manual operations, and meets the needs of large-scale production. The key to the automatic welding tooling for a muffler lies in the improvement of welding precision and production efficiency, and it can also handle mufflers of different shapes and sizes. Through the application of automatic welding technology and intelligent control systems, not only can the production efficiency be greatly improved, but also the consistency of welding quality can be ensured, and the errors caused by manual intervention can be reduced. The existing automatic welding tooling for mufflers usually cannot achieve automatic addition of welding rods, resulting in possible welding interruptions. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: an automatic welding tooling for a muffler, including a main body mechanism for adjusting the welding position. The main body mechanism includes a chassis, and a clamping mechanism for clamping the muffler to be welded and a welding mechanism for welding the muffler are arranged on the main body mechanism. The main body mechanism includes a column fixedly installed on the chassis, and a lifting ring is slidably installed on the column.

[0004] Further, the main body mechanism further includes a top plate fixedly installed on the column. A top motor is fixedly installed on the top plate, and a vertical lead screw is rotatably installed on the top plate. The vertical lead screw is rotatably installed with the chassis, and the lifting ring forms a threaded drive with the vertical lead screw.

[0005] Further, a fan is rotatably installed on the top plate, and the top motor drives the fan and the vertical lead screw to rotate through a transmission belt.

[0006] The top motor drives the fan and the vertical lead screw to rotate through belt drive. The rotation of the vertical lead screw drives the lifting ring to move up and down along the column, and at the same time, the rotation of the fan dissipates heat to the lower part.

[0007] Further, the clamping mechanism includes a bottom motor fixedly installed below the chassis. A clamping shell is fixedly installed on the chassis, and a central shaft is rotatably installed on the chassis. The bottom motor drives the central shaft to rotate through belt drive. A central rotating block is fixedly installed on the central shaft, and four clamping blocks are slidably installed on the chassis. A clamping column is fixedly installed on the clamping block, a pull rod is rotatably installed on the central rotating block, the pull rod is rotatably installed with the clamping block, and the clamping column is slidably installed with the clamping shell.

[0008] Furthermore, a vertical rack is fixedly installed on the chassis. A lifting block is slidably installed on the vertical rack. A spring is arranged between the lifting block and the vertical rack. A guiding gear is rotatably installed on the lifting block. The guiding gear meshes with the vertical rack. A lower pressing plate is fixedly installed on the lifting block. An upper pressing plate is slidably installed on the lower pressing plate. A pressing plate spring is arranged between the upper pressing plate and the lower pressing plate.

[0009] Furthermore, a winding drum is rotatably installed on the chassis. A pulling rope is wound around the winding drum. The other end of the pulling rope is fixedly installed with the lifting block. The central shaft drives the winding drum to rotate through belt drive and gear drive.

[0010] During use, place the muffler to be welded on the clamping shell, between the four clamping columns. Place another muffler to be welded on the muffler located on the clamping shell and adjust the welding position. The bottom motor drives the central shaft to rotate through the transmission belt. The central shaft drives the winding drum to rotate through belt drive and gear drive. The winding drum winds up the pulling rope, thereby driving the lifting block, the lower pressing plate and the upper pressing plate to descend, so that the upper pressing plate presses the upper muffler to be welded on the lower muffler to be welded. At the same time, the central shaft drives the central rotating block to rotate, thereby driving the four clamping blocks and the clamping columns to move inward through the pull rod, and clamping the lower muffler through the clamping columns. When the upper pressing plate contacts the upper muffler, the lower pressing plate continues to descend, so that the pressing plate spring is compressed. When the clamping columns clamp the lower muffler, the pressing plate spring is in a compressed state.

[0011] Furthermore, the welding mechanism includes a moving frame slidably installed on the lifting ring. A moving motor is fixedly installed on the moving frame. A roller is fixedly installed on the motor shaft of the moving motor. The roller rolls along the lifting ring. An extending frame is slidably installed on the moving frame. A welding torch is fixedly installed on the extending frame. An electric cylinder is fixedly installed on the moving frame. The output end of the electric cylinder is fixedly installed with the extending frame.

[0012] Furthermore, a welding rod holder is fixedly installed on the extending frame. A welding rod opening is fixedly installed on the welding rod holder. An advancing rod frame is fixedly installed on the welding rod holder. A pushing rod plate is slidably installed on the advancing rod frame. An advancing rod spring is arranged between the pushing rod plate and the advancing rod frame.

[0013] Furthermore, a pushing column is slidably installed on the welding rod holder. A rack is fixedly installed on the pushing column. A pushing spring is arranged between the pushing column and the welding rod holder. A welding rod motor is fixedly installed on the welding rod holder. A semi-tooth gear is fixedly installed on the motor shaft of the welding rod motor. The semi-tooth gear meshes with the rack. A pushing plate is fixedly installed below the pushing column. The pushing plate is slidably installed with the welding rod holder.

[0014] The telescopic movement of the electric cylinder drives the extension frame to slide relative to the moving frame, enabling the welding torch to reach the welding position. The up-and-down position is adjusted by the lifting of the lifting ring. The movement motor rotates to drive the rollers to rotate, causing the moving frame to slide around the lifting ring to cooperate with the welding. When in use, multiple welding rods are placed on the welding rod rack, and the multiple welding rods are tightened in the welding rod rack by the pushing plate. Only one welding rod is located in front of the pushing plate. During welding, the welding rod motor drives the semi-toothed gear to rotate, which drives the rack, the pushing column, and the pushing plate to push the welding rod in front of the pushing plate out of the welding rod opening. The pushing spring is stretched. As welding progresses, the welding rod is continuously consumed, and the pushing plate blocks the subsequent welding rods from entering the welding rod rack. When the welding rod is used up, the semi-toothed gear disengages from the rack, and the pushing spring rebounds, causing the pushing plate to return to its initial position. The feeding spring pushes the next welding rod into the welding rod rack through the pushing plate, and the welding rod reaches in front of the pushing plate, and so on, realizing the continuous feeding of the welding rod.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: (1) The main body mechanism and the welding mechanism provided in the present invention can cooperate to realize the up-and-down and left-and-right movement of the welding torch, enabling the welding torch to move along the weld to be welded, with high welding precision; (2) The clamping mechanism provided in the present invention can clamp the muffler to be welded on the side and top, keeping the muffler stable during welding and improving welding precision; (3) When the welding mechanism provided in the present invention performs welding, the welding rod can be automatically fed continuously, preventing the situation that the welding rod cannot be supplied during welding, which may lead to welding interruption, and ensuring the welding quality.

[0028] As Figure 2 shown, a fan 104 is rotatably installed on the top plate 102, and the top motor 103 drives the fan 104 and the vertical lead screw 105 to rotate through a transmission belt.

[0029] The top motor 103 drives the fan 104 and the vertical lead screw 105 to rotate through a belt drive. The rotation of the vertical lead screw 105 drives the lifting ring 106 to move up and down along the column 107. At the same time, the rotation of the fan 104 dissipates heat to the lower part.

[0030] AsFigures 3 - 5 As shown in the figure, the clamping mechanism includes a bottom motor 204 fixedly installed below the chassis 101. A clamping shell 201 is fixedly installed on the chassis 101. A central shaft 205 is rotatably installed on the chassis 101. The bottom motor 204 drives the central shaft 205 to rotate through a belt drive. A central rotating block 206 is fixedly installed on the central shaft 205.

[0031] As Figures 3 - 5 As shown in the figure, a vertical rack 202 is fixedly installed on the chassis 101. A lifting block 212 is slidably installed on the vertical rack 202.

[0032] As Figures 3 - 5 As shown in the figure, a winding drum 210 is rotatably installed on the chassis 101. A pulling rope 211 is wound around the winding drum 210. The other end of the pulling rope 211 is fixedly installed with the lifting block 212. The central shaft 205 drives the winding drum 210 to rotate through a belt drive and a gear drive.

[0033] During use, place the muffler to be welded on the clamping shell 201, between the four clamping columns 209. Place another muffler to be welded on the muffler located on the clamping shell 201 and adjust the welding position. The bottom motor 204 drives the central shaft 205 to rotate through a transmission belt. The central shaft 205 drives the winding drum 210 to rotate through a belt drive and a gear drive. The winding drum 210 winds up the pulling rope 211, thereby driving the lifting block 212, the lower pressing plate 213 and the upper pressing plate 214 to descend, so that the upper pressing plate 214 presses the upper muffler to be welded on the lower muffler to be welded. At the same time, the central shaft 205 drives the central rotating block 206 to rotate, thereby driving the four clamping blocks 208 and the clamping columns 209 to move inward through the pull rod 207, and clamping the lower muffler through the clamping columns 209. After the upper pressing plate 214 contacts the upper muffler, the lower pressing plate 213 continues to descend, so that the pressing plate spring 215 is compressed. When the clamping columns 209 clamp the lower muffler, the pressing plate spring 215 is in a compressed state.

[0034] As Figures 6 - 8As shown in the figure, the welding mechanism includes a moving frame 301 slidably mounted on the lifting ring 106. A moving motor 302 is fixedly mounted on the moving frame 301. A roller 303 is fixedly mounted on the motor shaft of the moving motor 302. The roller 303 rolls along the lifting ring 106. An extending frame 305 is slidably mounted on the moving frame 301. A welding torch 306 is fixedly mounted on the extending frame 305. An electric cylinder 304 is fixedly mounted on the moving frame 301. The output end of the electric cylinder 304 is fixedly mounted to the extending frame 305.

[0035] As Figures 6 - 8 shown in the figure, a welding rod holder 307 is fixedly mounted on the extending frame 305. A welding rod opening 310 is fixedly mounted on the welding rod holder 307. A rod feeding frame 315 is fixedly mounted on the welding rod holder 307. A rod pushing plate 316 is slidably mounted on the rod feeding frame 315. A rod feeding spring 314 is provided between the rod pushing plate 316 and the rod feeding frame 315.

[0036] As Figures 6 - 8 shown in the figure, a pushing column 312 is slidably mounted on the welding rod holder 307. A rack 311 is fixedly mounted on the pushing column 312. A pushing spring 313 is provided between the pushing column 312 and the welding rod holder 307. A welding rod motor 308 is fixedly mounted on the welding rod holder 307. A semi-tooth gear 309 is fixedly mounted on the motor shaft of the welding rod motor 308. The semi-tooth gear 309 meshes with the rack 311. A pushing plate 317 is fixedly mounted below the pushing column 312. The pushing plate 317 is slidably mounted on the welding rod holder 307.

[0037] The telescopic movement of the electric cylinder 304 drives the extending frame 305 to slide relative to the moving frame 301, so that the welding torch 306 reaches the welding position. The up and down position is adjusted by the lifting of the lifting ring 106. The rotation of the moving motor 302 drives the rotation of the roller 303, so that the moving frame 301 slides around the lifting ring 106 to cooperate with the welding. When in use, multiple welding rods are placed on the welding rod holder 307. The multiple welding rods are tightened in the welding rod holder 307 by the rod pushing plate 316. Only one welding rod is located in front of the pushing plate 317. When welding, the welding rod motor 308 drives the semi-tooth gear 309 to rotate, so as to drive the rack 311, the pushing column 312 and the pushing plate 317 to push the welding rod in front of the pushing plate 317 out from the welding rod opening 310. The pushing spring 313 is stretched. As the welding progresses, the welding rod is continuously consumed. The pushing plate 317 blocks the subsequent welding rods from entering the welding rod holder 307. When the welding rod is used up, the semi-tooth gear 309 disengages from the rack 311. The pushing spring 313 rebounds, so that the pushing plate 317 returns to the initial position. The rod feeding spring 314 pushes the next welding rod into the welding rod holder 307 through the rod pushing plate 316. The welding rod reaches in front of the pushing plate 317. This process is repeated to achieve the continuous feeding of the welding rod.

[0038] The working principle of an automatic welding tooling for a muffler disclosed in the present invention is as follows: The top motor 103 drives the fan 104 and the vertical lead screw 105 to rotate through belt drive. The rotation of the vertical lead screw 105 drives the lifting ring 106 to move up and down along the column 107. At the same time, the fan 104 rotates to dissipate heat downward. During use, the muffler to be welded is placed on the clamping shell 201, between the four clamping columns 209. Another muffler to be welded is placed on the muffler located on the clamping shell 201, and the welding position is adjusted. The bottom motor 204 drives the central shaft 205 to rotate through the transmission belt. The central shaft 205 drives the winding drum 210 to rotate through belt drive and gear drive. The winding drum 210 winds up the pulling rope 211, thereby driving the lifting block 212, the lower pressing plate 213 and the upper pressing plate 214 to descend, so that the upper pressing plate 214 presses the upper muffler to be welded against the lower muffler to be welded. At the same time, the central shaft 205 drives the central rotating block 206 to rotate, thereby driving the four clamping blocks 208 and the clamping columns 209 to move inward through the pull rod 207, and clamping the lower muffler through the clamping columns 209. When the upper pressing plate 214 contacts the upper muffler, the lower pressing plate 213 continues to descend, so that the pressing plate spring 215 is compressed. When the clamping columns 209 clamp the lower muffler, the pressing plate spring 215 is in a compressed state. The electric cylinder 304 expands and contracts to drive the extending frame 305 to slide relative to the moving frame 301, so that the welding torch 306 reaches the welding position. The up and down position is adjusted by the lifting of the lifting ring 106. The moving motor 302 rotates to drive the roller 303 to rotate, so that the moving frame 301 slides around the lifting ring 106 to cooperate with the welding. During use, multiple welding rods are placed on the welding rod rack 307. The multiple welding rods are tightened in the welding rod rack 307 by the pushing strip plate 316. Only one welding rod is located in front of the pushing plate 317. When welding, the welding rod motor 308 drives the semi-toothed gear 309 to rotate, thereby driving the rack 311, the pushing column 312 and the pushing plate 317 to push the welding rod in front of the pushing plate 317 out of the welding rod opening 310. The pushing spring 313 is stretched. As the welding progresses, the welding rod is continuously consumed. The pushing plate 317 blocks the subsequent welding rods from entering the welding rod rack 307. When the welding rod is used up, the semi-toothed gear 309 disengages from the rack 311, and the pushing spring 313 rebounds, so that the pushing plate 317 returns to the initial position. The feeding spring 314 pushes the next welding rod into the welding rod rack 307 through the pushing strip plate 316, and the welding rod reaches in front of the pushing plate 317. This process is repeated to achieve continuous feeding of the welding rod.

[0039] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered by the protection scope of the present invention.
