Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and particularly to a welding fixture with a flipping and positioning function. Background Technique

[0002] A welding device is a device system that forms a permanent connection by heating, pressurizing, or both, so that two or more metal or other material workpieces achieve atomic bonding. Its core function is to achieve the melting, diffusion, or plastic deformation of materials through energy conversion (such as arc, plasma arc, etc.), and finally form a high-quality welded joint. Welding devices are usually divided into automatic, semi-automatic arc, plasma arc welding machines, etc. When an automatic arc welding device is welding, a welding fixture with a flipping and positioning function is usually used to clamp and position the welded parts for efficient welding operations.

[0003] However, during flipping, it is easy for scattered welding slag to enter the seam to be welded, which will damage the continuity of the weld metal, easily cause cavities in the welded part after welding, increase the risk of crack generation, and reduce the welding efficiency.

[0004] Combining the above problems, we will find that the existing welding fixtures on the market are difficult to avoid the above-mentioned problems simultaneously during use, and even if they can be solved, external tools need to be used for cooperation, so that the desired effect cannot be achieved.

[0039] The telescopic end of the electric push rod 212 is fixedly connected to a connecting rod 213. Both sides of the connecting rod 213 are fixedly connected with guide blocks 214. Two groups of moving holes 215 are formed on the surface of the first flipping frame 14. The number of each group of moving holes 215 is two, and every two moving holes 215 are arranged vertically opposite to each other. The moving holes 215 communicate with the sliding groove 201.

The inner wall of the sliding block 218 is slidably connected to the surface of the first guide rod 219. A first spring 220 is movably sleeved on the surface of the first guide rod 219. Both ends of the first spring 220 are fixedly connected to the bottom of the sliding block 218 and the inner bottom of the moving groove 217 respectively. Through the setting of the moving groove 217 and the sliding block 218, the stability of the locking block 205 during vertical movement can be achieved.

[0041] A first torsion spring 221 is movably sleeved on the surface of the rotating rod 210. Both ends of the first torsion spring 221 are fixedly connected to one side of the jacking plate 209 and the inner wall of the placement groove 204 respectively.

The setting of the first torsion spring 221 can realize the reset of the rotation angle of the rotating rod 210. Through the setting of the guiding groove 222, the second guide rod 223 and the guiding plate 224, the movement of the first inclined block 211 can be guided, ensuring the stability of the first inclined block 211 during movement, thus ensuring the stable operation of the positioning mechanism 2.

[0042] The specific implementation of this embodiment is as follows: The flipping table body 1 cooperates with an automatic arc welding device for welding operations. The rotating disk 12 inside the flipping table body 1 is rotationally driven by a motor inside the flipping table body 1. The rotating ring 13 is driven to rotate by the rotating disk 12, the first flipping frame 14, the fixture plate 16, and the second flipping frame 15. The workpiece is clamped by the fixture plate 16, so as to realize the flipping and positioning of the workpiece during welding. The user places the four corners of the fixture plate 16 in the placement grooves 204, and starts the electric push rod 212 through the controller of the flipping table body 1, so that the electric push rod 212 extends. The extension of the electric push rod 212 drives the connecting rod 213 to move. The movement of the connecting rod 213 drives the guide block 214 to move. The movement of the guide block 214 drives the two moving blocks 216 to slide in the inner cavity of the movement holes 215. The movement of the moving blocks 216 drives the extension block 202 to move in the inner cavity of the sliding groove 201. The movement of the extension block 202 pushes the fixture plate 16 to move towards the second flipping frame 15. When it moves a certain distance, both sides of the fixture plate 16 squeeze the first inclined blocks 211 in the four placement grooves 204. After the first inclined blocks 211 receive the squeezing force, they generate an upward displacement. The movement of the first inclined blocks 211 is stably guided through the guide plate 224, the second guide rod 223, and the guide groove 222. The upward movement of the first inclined blocks 211 pushes the jacking plate 209 to flip upward. The rotation of the jacking plate 209 drives the rotating rod 210 to rotate. The rotation of the rotating rod 210 realizes the deformation of the first torsion spring 221. One end of the jacking plate 209 flips upward. Through the cooperation of the rotating rod 210, the jacking plate 209 rotates through the rotating column 225, driving the pressing plate 208 to move downward. When the pressing plate 208 moves downward, it applies a downward pressure to the inner bottom of the pressing groove 207. At the same time, the pressing plate 208 slides in the inner cavity of the pressing groove 207, thereby pushing the locking block 205 to move downward. The downward movement of the locking block 205 is stably guided through the first guide rod 219, the sliding block 218, and the movement groove 217. When the locking block 205 moves downward, it compresses the first spring 220. When the locking block 205 loses the downward pressure, the reaction force of the first spring 220 can realize the reset of the locking block 205 until one side of the fixture plate 16 is in close contact with the inner wall of the placement groove 204. At this time, the locking block 205 and the friction pad 206 are pressed to the position in contact with the fixture plate 16, that is, the friction pad 206 is in close contact with the top of the fixture plate 16, realizing the fastening and pressing of the fixture plate 16 and the positioning of the fixture plate 16.

[0043] Embodiment 2: Please refer to Figures 1 - 15 , the present invention provides a technical solution: a welding fixture with a flipping and positioning function. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0044] As a further limitation of the vibration mechanism 3 of the present invention, the vibration mechanism 3 includes a positioning cylinder 301 fixedly connected to the inner side of the support frame 11. The positioning cylinder 301 is located in the inner ring of the rotating ring 13. An arc-shaped rack 302 is fixedly connected to the inner wall of the rotating ring 13. A first gear 303 is rotatably connected to the inner side of the support frame 11 through a rotating shaft. A first cam 304 is fixedly connected to one side of the first gear 303. The teeth of the first gear 303 are engaged with the teeth of the arc-shaped rack 302. A displacement block 305 is slidably connected to the inner side of the support frame 11. The displacement block 305 is used in cooperation with the first cam 304. A first inclined groove 306 is formed on one side of the displacement block 305. A roller 307 is arranged in the inner cavity of the first inclined groove 306. The roller 307 is in contact with the inclined surface of the first inclined groove 306. One side of the roller 307 is provided with a mounting plate 308. The mounting plate 308 is rotatably connected to the roller 307 through a rotating shaft. A connecting column 309 is fixedly connected to one side of the mounting plate 308. One end of the connecting column 309 is fixedly connected to a pressing column 310. One end of the pressing column 310 is fixedly connected to a contact block 311. The contact block 311 is used in cooperation with the jig plate 16. By setting the vibration mechanism 3 and cooperating with the positioning mechanism 2, the lateral reciprocating pushing of the jig plate 16 can be realized through the rotation of the rotating ring 13, so that during the flipping process of the jig plate 16, shaking is carried out, the shaking frequency of the scattered welding slag is increased, the welding slag falls off, thereby reducing the probability of the welding slag entering the weld to be welded, ensuring the continuity of the weld metal, and improving the welding efficiency.

[0045] Two guiding strips 312 are fixedly connected to the surface of the connecting column 309. Two guiding tracks 313 are formed on the inner wall of the positioning cylinder 301. The surface of the guiding strip 312 is slidably connected to the inner cavity of the guiding track 313. A first tension spring 314 is fixedly connected to the inner side of the guiding track 313. One end of the first tension spring 314 is fixedly connected to one side of the guiding strip 312. A T-shaped groove 315 is formed on the inner side of the support frame 11. A T-shaped block 316 is slidably connected to the inner cavity of the T-shaped groove 315. A second tension spring 317 is fixedly connected to the inner side of the T-shaped groove 315. One end of the second tension spring 317 is fixedly connected to one side of the T-shaped block 316. One side of the T-shaped block 316 is fixedly connected to one side of the displacement block 305. By setting the cooperation of the guiding strip 312, the guiding track 313 and the first tension spring 314, the guiding of the connecting column 309 during displacement is realized, ensuring the stability of the connecting column 309 during displacement. Through the reaction force of the first tension spring 314, the reset of the connecting column 309 can be realized. The setting of the T-shaped groove 315 and the T-shaped block 316 can realize the stable guiding of the displacement block 305. The reaction force of the second tension spring 317 can realize the reset of the displacement block 305.

[0046] The specific implementation of this embodiment is as follows: When a rotation operation is required, the controller of the turntable body 1 controls the electric push rod 212 to retract a set distance. By the retraction of the electric push rod 212, the pushing force on the fixture plate 16 is reduced, thereby reducing the pushing force on the first inclined block 211. Due to the reaction force of the first spring 220, the first inclined block 211 moves downward. The distance that the electric push rod 212 retracts should ensure that the fixture plate 16 is always in contact with the first inclined block 211, ensuring the stability of the fixture plate 16. As the first flipping frame 14 rotates, it drives the fixture plate 16, the second flipping frame 15, and the rotating ring 13 to rotate. The rotation of the rotating ring 13 drives the arc-shaped rack 302 to rotate. The rotation of the arc-shaped rack 302 drives the first gear 303 to rotate. The rotation of the first gear 303 drives the first cam 304 to rotate. The protruding end of the first cam 304 squeezes the displacement block 305, causing the displacement block 305 to undergo a vertical displacement. When the displacement block 305 is displaced, it is guided by the T-shaped block 316 and the T-shaped groove 315, and at this time, the second tension spring 317 is stretched. When the displacement block 305 undergoes a vertical displacement, through the cooperation of the first inclined groove 306 and the roller 307, the mounting plate 308 and the connecting column 309 generate a lateral displacement. The lateral displacement of the connecting column 309 causes the extrusion column 310 to undergo a lateral displacement. The lateral displacement of the extrusion column 310 drives the contact box to push the fixture plate 16. Through the repeated squeezing of the displacement block 305 by the first cam 304, and the simultaneous cooperation of the reaction forces of the first spring 220 and the first torsion spring 221, multiple shakes of the fixture plate 16 are realized, thereby increasing the probability of slag shaking off. After the turntable body 1 performs a 180-degree flipping operation on the fixture plate 16, by starting the electric push rod 212, the electric push rod 212 is extended to re-clamp and position the fixture plate 16, facilitating the continuation of the welding operation.

[0047] Embodiment 3: Please refer to Figures 1 - 15 , the present invention provides a technical solution: A welding fixture with a flipping and positioning function. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0048] As a further limitation of the adhesion mechanism 4 of the present invention, the adhesion mechanism 4 includes a multi-stage electric telescopic rod 401 fixedly connected to the inner bottom of the slag collection box 5. The telescopic end of the multi-stage electric telescopic rod 401 is fixedly connected with a receiving box 402. A cleaning soft rubber 403 is placed in the inner cavity of the receiving box 402. Three stirring rods 404 are rotatably connected to the inner wall of the receiving box 402. One end of the middle stirring rod 404 penetrates to the outside of the receiving box 402 and is provided with two one-way bearings 405. The inner side of the inner ring of the one-way bearing 405 is fixedly connected to the surface of the middle stirring rod 404. One end of each of the other two stirring rods 404 penetrates to the outside of the receiving box 402 and is fixedly connected with a second gear 406. The surfaces of the outer rings of the two one-way bearings 405 are both fixedly connected with a third gear 407. A toothed belt 408 is commonly engaged with the surfaces of the third gear 407 and the second gear 406; by providing the adhesion mechanism 4, the cleaning soft rubber 403 can be in flexible and close contact with the workpiece, so that the cleaning soft rubber 403 adheres to the fine welding slag adhered to the welding seam of the workpiece. Cooperating with the vibration mechanism 3, the treatment of the welding slag is strengthened, and the welding slag is prevented from entering the welding seam, thereby improving the welding efficiency.

[0049] The other end of the middle stirring rod 404 penetrates to the outside of the receiving box 402 and is fixedly connected with a fifth gear 409. An activity groove 410 is opened on the inner side of the slag collection box 5, and a tooth groove 411 is opened on the inner side of the activity groove 410. The teeth of the fifth gear 409 are engaged with the tooth groove 411. A strip-shaped hole 412 is opened on one side of the receiving box 402. The number of the strip-shaped holes 412 is two, and the two strip-shaped holes 412 are arranged oppositely. A storage groove 413 is opened at the inner bottom of the strip-shaped hole 412; by providing the fifth gear 409, the activity groove 410 and the teeth, the vertical movement of the stirring rod 404 can drive the fifth gear 409 to move vertically. When the fifth gear 409 moves vertically, cooperating with the teeth in the activity groove 410, rotation can be realized, thereby driving the middle stirring rod 404 to rotate. The arrangement of the strip-shaped hole 412 and the storage groove 413 provides sufficient lateral movement space for the leveling of the cleaning soft rubber 403.

[0050] Two rotating rods 414 are rotatably connected to the inner wall of the storage groove 413. A transmission belt 415 is commonly driven and connected to the surfaces of the two rotating rods 414. A number of tooth blocks 416 are fixedly connected to the surface of the transmission belt 415. A sixth gear 417 is fixedly connected to the surface of the middle stirring rod 404. The sixth gear 417 is located in the inner cavity of the storage groove 413. The sixth gear 417 meshes with the tooth blocks 416. A connecting block 418 is fixedly connected to the surface of the transmission belt 415. A fixed rod 419 is commonly fixedly connected to the tops of the two connecting blocks 418. A pressure roller 420 is rotatably connected to the surface of the fixed rod 419. The pressure roller 420 contacts the cleaning soft rubber 403. The fixed rod 419 is slidably connected to the inner cavity of the strip-shaped hole 412; by setting the cooperation of the rotating rod 414, the transmission belt 415, the tooth block 416, the sixth gear 417, the connecting block 418, the fixed rod 419 and the pressure roller 420, the rotation of the transmission belt 415 is supported by the rotating rod 414. The transmission belt 415 is made of a metal material. When the sixth gear 417 rotates, the transmission belt 415 is driven to rotate through the tooth blocks 416. The rotation of the transmission belt 415 drives the connecting block 418 to move. The movement of the connecting block 418 drives the fixed rod 419 and the pressure roller 420 to move. When the pressure roller 420 moves, it rolls and flattens the top surface of the cleaning soft rubber 403.

[0051] The specific implementation of this embodiment is as follows: When the workpiece clamped by the fixture plate 16 is flipped by 180 degrees, the flipping operation of the flipping table body 1 is stopped, and the multiple electric telescopic rods 401 are started. The telescopic ends of the multiple electric telescopic rods 401 extend, driving the accommodating box 402 to move upward. When the accommodating box 402 moves upward, it drives the stirring rod 404 to move upward. The upward movement of the middle stirring rod 404 drives the fifth gear 409 to move upward. When the fifth gear 409 moves upward, it cooperates with the tooth groove 411 in the moving groove 410 to enable its own rotation, thereby driving the middle stirring rod 404 to rotate. Through the setting of the one-way bearing 405, when the accommodating box 402 moves upward, the rotation of the middle stirring rod 404 cannot drive the third gear 407 to rotate. The rotation of the middle stirring rod 404 drives the sixth gear 417 to rotate. The rotation of the sixth gear 417 cooperates with the tooth block 416 to make the transmission belt 415 rotate. The rotation of the transmission belt 415 drives the connecting block 418 to move. The movement of the connecting block 418 drives the fixed rod 419 and the pressing roller 420 to move. When the pressing roller 420 moves, it rolls and flattens the top surface of the cleaning soft rubber 403 until the workpiece is embedded in the cleaning soft rubber 403, realizing the flexible and close contact between the cleaning soft rubber 403 and the workpiece, so that the cleaning soft rubber 403 adheres to the welding slag at the welding seam of the workpiece. When the accommodating box 402 does not generate an upward displacement, the pressing roller 420 is located at one end of the strip hole 412. When the accommodating box 402 drives the fifth gear 409 to rise to the maximum height, the pressing roller 420 just moves to the other end of the strip hole 412, completing the primary flattening of the cleaning soft rubber 403. When the accommodating box 402 moves downward following the multiple electric telescopic rods 401, the fifth gear 409 rotates in the reverse direction in cooperation with the teeth, causing the pressing roller 420 to move toward the other end of the strip hole 412, and performing a secondary flattening operation on the top surface of the cleaning soft rubber 403, so that the adhered welding slag is pressed into the cleaning soft mud, avoiding affecting the next use. Due to the setting of the one-way bearing 405, when the fifth gear 409 rotates in the reverse direction, it drives the stirring rod 404 to rotate in the reverse direction. At this time, the one-way bearing 405 rotates following the stirring rod 404. The rotation of the one-way bearing 405 drives the third gear 407 to rotate. The rotation of the third gear 407 drives the second gear 406 to rotate through the toothed belt 408, thereby driving the other two stirring rods 404 to rotate. Through the simultaneous rotation of the three stirring rods 404, the cleaning soft rubber 403 adhered with welding slag is stirred, facilitating the next use, improving the adhesion effect on the welding slag, further ensuring that the welding slag is difficult to enter the welding seam, and improving the welding efficiency.
