[0022] Example: See Figure 1 － Figure 8The present invention provides a technical solution: a reversible welding machine for processing automobile parts, comprising: a machine base 1, a movable groove 5 is opened in the wall of the machine base 1; a support frame 2, the outer wall of the bottom of the support frame 2 is fixedly connected to the outer wall of the top of the machine base 1; a power transmission box 3, the outer wall of the power transmission box 3 is fixedly connected to the outer wall of the support frame 2 by bolts; an induction coil 4, the outer wall of the induction coil 4 is fixedly connected to the output end of the power transmission box 3; a reversing clamping device 6, the outer wall of the reversing clamping device 6 is fixedly connected to the outer wall of the machine base 1; the reversing clamping device 6 comprises a DC motor 61, the output end of the DC motor 61 is fixedly connected to a bidirectional screw 62, the outer wall of the bidirectional screw 62 is rotatably connected to a positioning and cleaning device 63, the end of the positioning and cleaning device 63 close to the DC motor 61 is provided with a placing device 64, and the end of the positioning and cleaning device 63 away from the DC motor 61 is provided with a rotating device 65;The placing device 64 includes a first slider 641, the inner wall of the first slider 641 is threadedly connected to the outer wall of the bidirectional screw 62 through a first thread groove 642, and the first thread groove 642 is opened in the wall of the first slider 641, the inner wall of the first slider 641 is fixedly connected to a first tooth plate 643, the outer wall of the top of the first slider 641 is fixedly connected to a fixing frame 644, the outer wall of the top of the fixing frame 644 is fixedly connected to a driving device 645, the inner wall of the middle part of the first slider 641 is fixedly connected to a first support ring 646, and the outer wall of the first support ring 646 is fixedly connected to the inner wall of the middle part of the first slider 641. A fixing ring 647 is connected, and the outer wall of the fixing ring 647 is slidably connected to the adjusting device 648 through a hexagonal groove 6410, and the hexagonal groove 6410 is opened in the wall of the fixing ring 647. The inner wall of the adjusting device 648 is slidably connected to the worm gear 649 through a limiting groove 6411, and the limiting groove 6411 is opened in the wall of the worm gear 649. The outer wall of the first sliding block 641 is slidably connected to the outer wall of the machine base 1 through the movable groove 5. The DC motor 61 in the flip clamping device 6 is the main power source. When the DC motor 61 is started, it drives the bidirectional screw 62 to rotate. The placing device 64 and the rotating device 65 can move relative to each other through the opposite threads at both ends. The first slider 641 of the placing device 64 is threadedly connected with the bidirectional screw 62 through the first thread groove 642. As the bidirectional screw 62 rotates, the first slider 641 can slide in the movable groove 5. The first tooth plate 643 on the inner wall of the first slider 641 is meshed with one of the gear rods 634 in the positioning and cleaning device 63. The driving device 645 on the fixing frame 644 at the top of the first slider 641 plays an important role in the process of clamping the mother piece. The servo motor 6451 in the driving device 645 drives the driving rod 6452 to rotate, and the worm 6453 connected to the driving rod 6452 meshes with the worm wheel 649, and the worm 6453 drives the worm wheel 649 to rotate. When the worm wheel 649 rotates, the position of the connecting rod 6481 is changed by the limiting groove 6411 provided on itself, thereby changing the position of the movable box 6482. Since the movable box 6482 slides in the hexagonal slide groove 6410 through the limiting block 6483, the six adjustment devices 648 will move as a whole to form an iris structure and then clamp the mother part. ;

[0023] The adjusting device 648 includes a connecting rod 6481, both ends of the connecting rod 6481 are fixedly connected with a movable box 6482, a side of the movable box 6482 away from the connecting rod 6481 is fixedly connected with a limiting block 6483, the inner side wall of the movable box 6482 is fixedly connected with a micro cylinder 6484, the output end of the micro cylinder 6484 is fixedly connected with a limiting rod 6485, the outer wall of the limiting rod 6485 is slidably connected with an adjusting rod 6486, the outer wall of the adjusting rod 6486 is rotatably connected with a limiting wheel 6487, the end of the adjusting rod 6486 away from the limiting wheel 6487 is fixedly connected with a pushing block 6488, and the end of the pushing block 6488 away from the adjusting rod 6486 is rotatably connected with a roller 6489. When the mother part is moved, the clamping surface of the mother part can be changed by the adjusting device 648. The specific process is that the adjusting device 648 on the fixed ring 647 drives the limiting rod 6485 of the port to slide in the adjusting rod 6486 through the extension and contraction of the micro cylinder 6484, and then drives the adjusting rod 6486 to move in the movable box 6482. The adjusting rod 6486 rolls on the arc position in the movable box 6482 through the limiting wheel 6487. During the movement, the pushing block 6488 is pushed by the adjusting rod 6486 and restricted by the movable box 6482, so that the pushing block 6488 extends out of the movable box 6482, so that the roller 6489 is pushed out, and the surface of the roller 6489 is used to replace the previous contact surface between the outside of the movable box 6482 and the mother part, so that the mother part is easy to flip.

[0024] The side wall of the adjusting rod 6486 is slidably connected to the side wall inside the movable box 6482, the inner wall of the movable box 6482 is rollingly connected to the outer wall of the limiting wheel 6487, the outer wall of the movable box 6482 is fixedly connected to the outer wall of the fixing ring 647, the outer wall of the fixing ring 647 is slidably connected to the outer wall of the limiting block 6483 through the hexagonal slide groove 6410, and the outer wall of the connecting rod 6481 is slidably connected to the inner wall of the worm gear 649 through the limiting groove 6411.

[0025] The driving device 645 includes a servo motor 6451, the output end of the servo motor 6451 is fixedly connected to a driving rod 6452, the end of the driving rod 6452 away from the servo motor 6451 is fixedly connected to a worm 6453, the end of the worm 6453 away from the driving rod 6452 is fixedly connected to a threaded rod 6454, the outer wall of the worm 6453 is rotatably connected to a limiting cylinder 6455, the inner wall of the limiting cylinder 6455 is slidably connected to an internal threaded sleeve 6456, the inner wall of the internal threaded sleeve 6456 is symmetrically rotatably connected to a connecting rod 6457, the end of the connecting rod 6457 away from the internal threaded sleeve 6456 is rotatably connected to a rotating plate 6458, and the outer wall of the rotating plate 6458 is rotatably connected to a fixed plate 6459, the driving device 645 drives the worm 6453 to rotate the worm wheel 649. At the same time, since the threaded rod 6454 on the worm 6453 is threadedly connected with the internal threaded sleeve 6456, the internal threaded sleeve 6456 will move along the guide of the limiting cylinder 6455 and approach the position of the fixed plate 6459. During the movement, the internal threaded sleeve 6456 will push the connecting rod 6457 to move, and the other end of the connecting rod 6457 is connected to the rotating plate 6458. Therefore, the moving internal threaded sleeve 6456 will expand the rotating plates 6458 on both sides of the fixed plate 6459 through the connecting rod 6457. Since there is a warning structure on the fixed plate 6459, the staff can be reminded to be careful of high temperature.

[0026] The outer wall of the fixed plate 6459 is fixedly connected to the outer wall of the limiting cylinder 6455, the side wall of the limiting cylinder 6455 is fixedly connected to the side wall of the first support ring 646, the outer wall of the bottom of the servo motor 6451 is fixedly connected to the outer wall of the top of the fixed frame 644, the worm 6453 is meshed with the worm wheel 649, and the outer wall of the threaded rod 6454 is threadedly connected to the outer surface of the internal threaded sleeve 6456.

[0027] The positioning and cleaning device 63 includes an arc block 631, the inner wall of which is fixedly connected with a positioning tube 632, the inner wall of which is slidably connected with the outer wall of the first tooth plate 643 via a sliding groove 633, and the sliding groove 633 is provided in the wall of the arc block 631, the inner wall of the arc block 631 is obliquely symmetrically connected with a gear rod 634 for rotation, the outer wall of the gear rod 634 is rollingly connected with a transmission belt 635, the outer wall of the transmission belt 635 is rollingly connected with a positioning rod 636, the outer wall of the positioning rod 636 is fixedly connected with a cleaning roller 637, the arc block 631 of the positioning and cleaning device 63 is fixed on the machine base 1, the bidirectional screw 62 is rotated in the positioning tube 632 in the arc block 631, and one of the arc block 631 is close to the placement device 6 The gear rod 634 of the arc block 631 is meshed with the first tooth plate 643. When the first slider 641 moves in the sliding groove 633, the first tooth plate 643 drives the gear rod 634 to rotate. The gear rod 634 drives the cleaning roller 637 on the positioning rod 636 to rotate through the transmission belt 635. Similarly, the cleaning roller 637 at the other end of the arc block 631 also rotates in this way. The difference is that the driving force comes from the second tooth plate 653. When welding is completed, the clamping of the rotating device 65 on the weldment is released, and the DC motor 61 is started at the same time to rotate the bidirectional screw 62, so that the placing device 64 and the rotating device 65 are separated from each other. At this time, the cleaning rollers 637 on both sides rotate in opposite directions. The cleaning rollers 637 that rotate at the same time can concentrate impurities at both ends below the welding area.

[0028] The outer wall of the arc block 631 is fixedly connected to the outer wall of the machine base 1 , the outer wall of the gear rod 634 is meshed with the outer wall of the first tooth plate 643 , the outer wall of the positioning tube 632 is rotatably connected to the outer wall of the bidirectional screw 62 , and the outer wall of the positioning rod 636 is fixedly connected to the outer wall of the machine base 1 .

[0029] The rotating device 65 includes a second slider 651, the inner wall of the second slider 651 is threadedly connected to the outer wall of the bidirectional screw 62 through a second thread groove 652, the outer wall of the bottom of the second support ring 654 is fixedly connected to the second tooth plate 653, the outer wall of the top of the second slider 651 is fixedly connected to the second support ring 654, the outer wall of the second support ring 654 is rotatably connected to the rotating cylinder 655, the inner wall of the rotating cylinder 655 is symmetrically slidably connected to the clamping block 656, the outer wall of the clamping block 656 is fixedly connected to the tension spring 657, the outer side of the tension spring 657 is provided with a fixed tube 658, and the rotating device 65 The second slider 651 is threadedly connected to the bidirectional screw 62 through the second threaded groove 652, and slides in the movable groove 5 as the bidirectional screw 62 rotates. The second tooth plate 653 on the second support ring 654 at the top of the second slider 651 is engaged with another obliquely symmetrical gear rod 634 in the arc block 631. When the second slider 651 moves, the gear rod 634 there will rotate along with the movement of the second tooth plate 653. The inner wall of the rotating cylinder 655 rotating on the second support ring 654 is slid with a clamping block 656, and the clamping block 656 slides in the fixed tube 658 through a tension spring 657.

[0030] The outer wall of the fixed tube 658 is fixedly connected to the outer wall of the rotating cylinder 655, the inner wall of the fixed tube 658 is slidably connected to the outer wall of the clamping block 656, the outer wall of the second slider 651 is slidably connected to the outer wall of the base 1 through the movable groove 5, the outer wall of the second tooth plate 653 is slidably connected to the inner wall of the arc block 631, and the outer wall of the second tooth plate 653 is meshed with the outer wall of the gear rod 634. When the weldment needs to be clamped, the clamping block 656 is pulled to expand toward the outside of the rotating cylinder 655. At this time, the tension spring 657 stretches and generates elastic force. When clamping is required, only the force applied to the clamping block 656 needs to be released, and the clamping block 656 is moved close to the weldment under the action of the elastic force of the tension spring 657, so that the weldment of the automotive accessories can be clamped.

[0031] Working principle: When in use, the base 1 provides stable support for the entire welding machine, and the movable groove 5 in the wall provides a sliding track for the components of the flip clamping device 6. The support frame 2 is fixedly connected to the base 1 to support the power transmission box 3. The power transmission box 3 is fixed to the support frame 2 by bolts, and its output end is connected to the induction coil 4. The induction coil 4 cuts the inside of the metal through magnetic induction lines, thereby heating the metal to achieve brazing of automotive parts. Induction welding has fast heating speed, precise temperature control, uniform heating, and energy saving and environmental protection. The DC motor 61 in the flip clamping device 6 is the main power source. When the DC motor 61 is started, it drives the bidirectional screw 62 to rotate, and the placement device 64 and the rotation device 65 are relatively close to and relatively far away from each other through the opposite threads at both ends. When the mother piece to be welded is placed on the placement device 64, the rotation device 65 is used to clamp the weldment, and then control the two to approach each other and cooperate with the brazing material to perform the welding process; The first slider 641 of the placement device 64 is threadedly connected to the bidirectional screw 62 through the first thread groove 642. As the bidirectional screw 62 rotates, the first slider 641 can slide in the movable groove 5. The first tooth plate 643 on the inner wall of the first slider 641 is meshed with one of the gear rods 634 in the positioning and cleaning device 63. The driving device 645 on the fixing frame 644 at the top of the first slider 641 plays an important role in the process of clamping the mother part. The servo motor 6451 in the driving device 645 drives the driving rod 6452 to rotate, and the worm 645 connected to the driving rod 6452 is rotated. 3 is meshed with the worm gear 649, and the worm 6453 drives the worm gear 649 to rotate. When the worm gear 649 rotates, the position of the connecting rod 6481 is changed by the limiting groove 6411 provided on itself, thereby changing the position of the movable box 6482. Since the movable box 6482 slides in the hexagonal slide groove 6410 through the limiting block 6483, the six adjustment devices 648 will move as a whole to form an iris structure to clamp the mother part. The placement device 64 can control the movement of the adjustment device 648, thereby completing the clamping operation of the mother part entering the interior of the first support ring 646; At the same time, the second slider 651 of the rotating device 65 is threadedly connected to the bidirectional screw 62 through the second thread groove 652. As the bidirectional screw 62 rotates, it slides in the movable groove 5. The second tooth plate 653 on the second support ring 654 at the top of the second slider 651 is meshed with another obliquely symmetrical gear rod 634 in the arc block 631. When the second slider 651 moves, the gear rod 634 at this location will rotate along with the movement of the second tooth plate 653, and the rotating cylinder 655 on the second support ring 654 will rotate. The wall slide has a clamping block 656, which slides in the fixed tube 658 through the tension spring 657. When the weldment needs to be clamped, the clamping block 656 is pulled to expand toward the outside of the rotating cylinder 655. At this time, the tension spring 657 stretches and generates elastic force. When clamping is required, it is only necessary to release the force applied to the clamping block 656, and move the clamping block 656 close to the weldment under the action of the elastic force of the tension spring 657, so that the weldment of the automobile part can be clamped, and the rotating cylinder 655 can be rotated at the same time to facilitate the flipping operation of the part during welding; When it is necessary to rotate the mother part and the welded part after welding, the clamping surface of the mother part can be changed by the adjusting device 648. The specific process is that the adjusting device 648 on the fixed ring 647 drives the limiting rod 6485 of the port to slide in the adjusting rod 6486 through the extension and contraction of the micro cylinder 6484, and then drives the adjusting rod 6486 to move in the movable box 6482. The adjusting rod 6486 rolls on the arc position in the movable box 6482 through the limiting wheel 6487. During the movement, the pushing block 6488 is pushed by the adjusting rod 6486 and restricted by the movable box 6482, so that the pushing block 6488 extends out of the movable box 6482, so that the roller 6489 is pushed out, and the contact surface between the outer side of the movable box 6482 and the mother part is replaced with the surface of the roller 6489, so that the mother part is easy to flip. The adjusting device 648 can be adaptively adjusted according to the shape of the automobile accessories, ensuring the stable support of the accessories while assisting the rotating device 65 to rotate the welded mother part and the weld. While the driving device 645 drives the worm 6453 to rotate the worm wheel 649, since the threaded rod 6454 on the worm 6453 is threadedly connected with the internal threaded sleeve 6456, the internal threaded sleeve 6456 will move along the guide of the limit cylinder 6455 and approach the position of the fixed plate 6459. During the movement, the internal threaded sleeve 6456 will push the connecting rod 6457 to move, and the other end of the connecting rod 6457 is connected to the rotating plate 6458. Therefore, the moving internal threaded sleeve 6456 will be moved by the connecting rod 645 7. Unfold the rotating plates 6458 on both sides of the fixed plate 6459. Since the fixed plate 6459 has a warning structure, it can remind the staff to be careful of high temperature. During the induction welding process, high temperature only exists on the weldment and the mother part. Since there is no large amount of smoke and no obvious light during the welding process, it is easy for the staff to misjudge the temperature of the welding process. The warning of the fixed plate 6459 is used to remind the staff. At the same time, the unfolded rotating plate 6458 can also block the staff and the mother part, thereby preventing the staff from accidentally directly contacting the high-temperature mother part and causing damage; The arc block 631 of the positioning and cleaning device 63 is fixed on the machine base 1. The bidirectional screw 62 rotates in the positioning tube 632 in the arc block 631. The gear rod 634 near the placement device 64 in one of the arc block 631 is meshed with the first tooth plate 643. When the first slider 641 moves in the sliding groove 633, the first tooth plate 643 drives the gear rod 634 to rotate. The gear rod 634 drives the cleaning roller 637 on the positioning rod 636 to rotate through the transmission belt 635. Similarly, the cleaning roller 637 at the other end of the arc block 631 also rotates in this way. The difference is that the driving The power comes from the second tooth plate 653. When welding is completed, the clamping of the rotating device 65 on the weldment is released, and the DC motor 61 is started at the same time to rotate the bidirectional screw 62, so that the placement device 64 and the rotating device 65 move away from each other. At this time, the cleaning rollers 637 on both sides rotate in opposite directions. At the same time, the rotating cleaning rollers 637 can concentrate impurities at both ends below the welding area. Due to the arc position of the arc block 631, the middle area at the top of the arc block 631 is easier to clean, preventing the accumulation of impurities at both ends from making it difficult to use the induction coil 4 normally, thereby ensuring a more stable welding process.
