Description

Technical Field

[0001] The invention relates to the technical field of metal welding, in particular to a welding device for metal plate processing. Background Art

[0002] The welding device for metal plate processing is a crucial equipment in the metal plate processing process. It is mainly used to connect metal plates together through welding technology to form structural parts or components. This welding device usually adopts laser welding, arc welding or plasma welding, etc., so as to ensure firm and precise welding between metal plates.

[0003] In the current metal plate welding operation, although it is a common practice to use manual handheld welding equipment to complete the welding operation between adjacent metal plates, this traditional method has exposed significant shortcomings when facing large metal plates. Specifically, when the size of the metal plate is large, workers often need to climb onto the metal plate for welding, which not only increases the difficulty of the operation, but also poses a potential threat to the safety and health of workers. More importantly, the welding process under manual operation is extremely susceptible to human factors. During the welding process, even if the worker only makes a small movement, it may cause the position relationship between the two adjacent metal plates to shift, thereby affecting the accuracy and quality of the welding. In addition, there is another serious problem when manually standing on the metal plate for welding. Since the metal plate itself has a certain elasticity and weight, when the worker operates on it, it is easy to cause the metal plate to be slightly bent and deformed before welding. Although this deformation may not be obvious, it will generate stress inside the metal plate. Once the welding is completed, these stresses will be released during the cooling process of the welded joint, resulting in bending and deformation of the metal plate. This deformation not only affects the appearance of the metal plate, but is also likely to have an adverse effect on its structural strength and performance. To this end, we propose a welding device for metal plate processing. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the welding device for metal plate processing is used, first, the device provides a stable working platform through the supporting mechanism, with the base plate as the foundation. The jacking hydraulic rods fixedly connected at the four diagonal points of its upper end can adjust the height of the two horizontal moving mechanisms, two extension mechanisms and driving mechanisms at the upper part according to needs. Before the welding operation begins, the two steel plates are placed above the two first clamping units and are initially positioned and clamped by the two first clamping units. This step effectively avoids the problem of metal plate position deviation that may be caused by manual hand-held welding equipment, ensuring the accuracy of welding. Subsequently, the two first clamping units are controlled to operate through two control mechanisms to further stabilize and determine the position of the steel plates. In order to further improve the welding quality, the device is also provided with a second positioning and clamping mechanism. During the welding process, the extension mechanism is used to adjust the height of the two horizontal moving mechanisms, two extension mechanisms and driving mechanisms. This step effectively prevents the bending deformation of the metal plate caused by stress release during welding. On this basis, the welding mechanism, the two stretching mechanisms and the two second positioning and clamping mechanisms move synchronously and start welding the two steel plates. Since the welding mechanism is located at the center between the two first clamping units, the stability and uniformity of the welding process can be ensured. The setting of the three horizontal moving mechanisms enables the stretching mechanism, the two welding mechanisms and the two second positioning and clamping mechanisms to move freely in the horizontal direction to adapt to the welding needs of metal plates of different sizes and shapes. The synchronization mechanism and the synchronous transmission mechanism ensure the coordinated operation of the three horizontal moving mechanisms and improve the working efficiency.

The first driving gear 206 arranged in the mounting groove 205 and the first transmission gear 208 on the two synchronous shafts 207 constitute a gear meshing transmission system. When the first driving gear 206 rotates, it will drive the two synchronous shafts 207 to rotate synchronously. The two synchronous shafts 207 not only participate in the synchronous rotation of the first transmission gear 208, but also have a first sprocket 2016 fixed on their top ends for subsequent first chain 2019 transmission. The positioning shaft 2012 serves as a key component connecting the first driving gear 206 and the worm wheel 2013. It will rotate synchronously with the worm wheel 2013. The spiral toothing transmission between the worm wheel 2013 and the worm 2014 realizes the change of the transmission ratio, thereby adjusting the clamping force of the clamping wheel 2026. The other end of the worm 2014 is fixedly connected to the driving shaft 2015. When the control mechanism 10 drives the driving shaft 2015 When the synchronizing shaft 207 rotates, the worm 2014 and the worm wheel 2013 are driven to rotate, and then the first driving gear 206 is driven to rotate through the positioning shaft 2012, so as to start the entire transmission system. The first sprocket 2016 and the second sprocket 2018 are connected through the first chain 2019 to form a chain transmission system. When the synchronizing shaft 207 rotates, the first sprocket 2016 is driven to rotate, and then the second sprocket 2018 is driven to rotate through the first chain 2019. This transmission process realizes the rotation of the synchronizing shaft 207. The rotational motion is converted into the linear motion of the chain. The linear motion of the first chain 2019 finally drives the slider 2024 to slide in the first movable groove 2021 on the protective cover 2020. The slider 2024 ensures the stability and direction of sliding through the cooperation of the guide rail 2023 and the guide groove 2022. The clamping wheel 2026 rotating on the central axis 2025 fixed inside the slider 2024 directly contacts the clamped steel plate 12, thereby realizing the first clamping and positioning function of the steel plate 12.

The two first transmission rods 1003 close to the two second support blocks 203 are fixedly connected to the two drive shafts 2015 respectively. This connection point transmits the power of the control mechanism 10 to the worm 2014 of the first positioning clamping mechanism 2. A synchronization rod 1006 is fixedly connected between the two first bevel gears 1004 on the side away from the two second support blocks 203. This design ensures the synchronous rotation between the two groups of first transmission rods 1003 and the first bevel gears 1004. The handwheel 1007 allows the operator to drive the operation of the entire control mechanism 10 by manually rotating the handwheel 1007, thereby realizing precise control of the first positioning clamping mechanism 2.

The upper center of the chassis 401 is fixedly connected to an electric push rod 402, and the output end of the electric push rod 402 is fixedly connected to a welding gun 403.

[0039] Furthermore, the three horizontal moving mechanisms 3 all include a first base plate 301, one of the three first base plates 301 is fixedly connected to the center of the upper end of the base plate 101, serving as a stable foundation for the entire system, and the other two are fixedly connected to the output ends of the two lifting hydraulic rods 102 on one side and the other side, respectively. Such a design enables the two movable horizontal moving mechanisms 3 to be driven by the lifting hydraulic rods 102 to achieve vertical lifting and lowering, thereby adjusting their working heights.

Finally, through the drive of the electric push rod 402, the welding position of the welding gun 403 can be accurately adjusted. This series of structural cooperation together constitutes an efficient and stable welding automation system.

[0040] In the preferred technical solution of this embodiment, please refer to Figure 3As shown, the synchronous transmission mechanism 9 includes two sixth connecting plates 901 and two sixth bevel gears 902. The two sixth connecting plates 901 are respectively fixedly connected to the center of one side of the two first base plates 301 at the upper position, and the two sixth bevel gears 902 are respectively fixedly connected to the two first screw rods 303 at the upper position close to the two sixth connecting plates 901. The inner centers of the two sixth connecting plates 901 are both rotatably sleeved with spline sleeves 903 through bearings, and the outer sides of the two spline sleeves 903 are both fixedly sleeved with seventh bevel gears 904 at the upper positions. There is a gear meshing transmission between the sixth bevel gear 902 and the seventh bevel gear 904 at one side, and there is a gear meshing transmission between the sixth bevel gear 902 and the seventh bevel gear 904 at the other side.

[0041] Furthermore, the synchronous transmission mechanism 9 is designed to ensure that the first screw rods 303 in the two horizontal moving mechanisms 3 at the upper positions can rotate synchronously and coordinately. The synchronous transmission mechanism 9 is mainly composed of two sixth connecting plates 901 and two sixth bevel gears 902, and is combined with the components in the horizontal moving mechanism 3 to realize the function of synchronous transmission. The two sixth connecting plates 901 are respectively fixedly connected to the center of one side of the two first base plates 301 at the upper positions, providing necessary support and connection points for subsequent synchronous transmission. The two sixth bevel gears 902 are respectively fixedly connected to the two first screw rods 303 at the upper positions, close to one side of the two sixth connecting plates 901. The rotation of the sixth bevel gear 902 can be directly transmitted to the first screw rod 303. At the inner center of the six connecting plates 901, a spline sleeve 903 is rotatably sleeved through a bearing. This design not only ensures that the spline sleeve 903 can rotate flexibly, but also provides necessary support for its subsequent combination with the seventh bevel gear 904. A seventh bevel gear 904 is fixedly sleeved on the upper outer side of the two spline sleeves 903. The gear meshing transmission between the two seventh bevel gears 904 and the two sixth bevel gears 902 is the basis of the entire synchronous transmission mechanism 9. The sixth bevel gear 902 on one side and the corresponding seventh bevel gear 904 are gear meshing transmission. Similarly, the sixth bevel gear 902 on the other side is also gear meshing transmission with the corresponding seventh bevel gear 904, and the rotation of the two spline sleeves 903 is driven by the synchronous mechanism 5.

[0042] In the preferred technical solution of this embodiment, please refer to Figure 9-10As shown, the synchronization mechanism 5 includes a U-shaped frame 501 and a first motor 502. The U-shaped frame 501 is fixedly connected to one side of the center of the upper end of the substrate 101. The first motor 502 is fixedly connected to one side of the center of the upper end of the substrate 101 near the U-shaped frame 501. The U-shaped frame 501 is fixedly connected to both ends of the center of one side near the first motor 502. The upper ends of the two strip connecting plates 503 are fixedly connected to positioning plates 504. The center of the U-shaped frame 501 is rotatably sleeved with a second transmission rod 505 through a bearing. The upper end of the second transmission rod 505 is fixedly connected to the first The first driving wheel 506 is fixedly connected to the second driving wheel 507 at the upper end. The first transmission wheel 508 is rotatably sleeved at both ends of the inner center of the U-shaped frame 501 through bearings. The first driving wheel 506 and the first transmission wheel 508 at one side are sleeved with a first transmission belt 509. The second driving wheel 507 and the first transmission wheel 508 at the other side are sleeved with a second transmission belt 5010. The inner centers of the two positioning plates 504 are rotatably sleeved with spline shafts 5011 through bearings. The lower ends of the two spline shafts 5011 are respectively fixedly connected to the two first transmission wheels 508. At the center of the upper end, the output end of the first motor 502 is fixedly connected to the second driving gear 5012, the center of the lower end of the U-shaped frame 501 is fixedly connected to the side plates 5014 on both sides, the lower ends of the two side plates 5014 are fixedly connected to the second bottom plate 5013, the center of the upper end of the second bottom plate 5013 is rotatably sleeved with a second bevel gear 5015 through a bearing, the inner centers of the two side plates 5014 are rotatably sleeved with a first transmission shaft 5016 through a bearing, the ends of the two first transmission shafts 5016 close to each other are fixedly connected to the third bevel gear 5017, and the two third bevel gears 5017 are connected to the second There is gear meshing transmission between the bevel gears 5015, the lower end of the second transmission rod 505 is fixedly connected to the center of the upper end of the second bevel gear 5015, the first transmission shaft 5016 away from the first motor 502 is fixedly connected to the side of the first screw rod 303 at the bottom, and a second transmission gear 5018 is fixedly sleeved on the outer side of the first transmission shaft 5016 close to the first motor 502 and away from the third bevel gear 5017. There is gear meshing transmission between the second transmission gear 5018 and the second driving gear 5012, and two spline sleeves 903 are respectively slidably sleeved on the outer sides of the two spline shafts 5011.

[0043] Furthermore, when the first motor 502 is started, its output end drives the second driving gear 5012 to rotate. Since the second transmission gear 5018 and the second driving gear 5012 are gear meshing transmission, the second transmission gear 5018 will also rotate accordingly. The second transmission gear 5018 is fixedly sleeved on the first transmission shaft 5016 close to the first motor 502 side, so the first transmission shaft 5016 will also rotate accordingly. The ends of the two first transmission shafts 5016 close to each other are fixedly connected with the third bevel gear 5017. The two third bevel gears 5017 and the second bevel gear 5015 are also gear meshing transmission. Therefore, when the first transmission shaft 5016 close to the first motor 502 side rotates, it will drive the two third bevel gears 5017 to rotate synchronously, thereby driving the second bevel gear 5015 to rotate. The first driving wheel 506 is connected to the first transmission wheel 508 on one side through the first transmission belt 509, and the second driving wheel 507 is connected to the first transmission wheel 508 at the other side through the second transmission belt 5010. The design of this transmission belt allows the two first transmission wheels 508 to rotate at the same speed and direction when the first drive wheel 506 and the second drive wheel 507 rotate. Since the lower ends of the two spline shafts 5011 are respectively fixedly connected to the centers of the upper ends of the two first transmission wheels 508, when the first transmission wheel 508 rotates, the spline shafts 5011 will be driven to rotate. The two spline sleeves 903 are respectively slidably sleeved on the outsides of the two spline shafts 5011. This sliding sleeve design allows the spline sleeves 903 to slide on the spline shafts 5011 while maintaining synchronous rotation. The first transmission shaft 5016 away from the side of the first motor 502 is fixedly connected to the side of the first screw rod 303 at the bottom. Therefore, when the first transmission shaft 5016 rotates, the first screw rod 303 at the bottom will be driven to rotate synchronously, thereby realizing the driving and control of the horizontal moving mechanism 3.

[0044] In the preferred technical solution of this embodiment, please refer to Fig.12As shown, the two extension mechanisms 6 are respectively arranged at both sides of the center of the upper end of the support plate 11, and the extension mechanism 6 includes a first sliding frame 602, the first sliding frame 602 is fixedly connected to the center of the upper end of the support plate 11 at one side, the inside of the first sliding frame 602 is rotatably connected to a second screw rod 603 through a bearing at one side, and a fourth bevel gear 604 is fixedly connected to one side of the second screw rod 603, and a first sliding groove 605 is opened at the center of both inner walls of the first sliding frame 602, a protective cover 606 is fixedly connected to the upper end of the first sliding frame 602, a rack 607 is fixedly connected to the center of the upper end of the protective cover 606, and a second movable groove is opened through the center of the upper part of the temporal part of the protective cover 606 The first slide frame 602 has a first fixed block 609 fixedly connected to one side of the upper end thereof, a second slide frame 6010 is slidably sleeved inside the first slide frame 602, a side of the second slide frame 6010 near the fourth bevel gear 604 is threadedly sleeved on the outside of the second screw rod 603, first slide rails 6011 are fixedly connected to the centers of both sides of the second slide frame 6010, two first slide rails 6011 are respectively slidably sleeved inside the two first slide grooves 605, a second slide groove 6012 is opened at the center of both inner walls of the second slide frame 6010, a second transmission is rotatably sleeved through a bearing at the center of the upper end of the second slide frame 6010 near the fourth bevel gear 604. The outer side of the second transmission shaft 6013 is fixedly sleeved with a third sprocket 6014 at the lower part, and the outer side of the second transmission shaft 6013 is slidably sleeved inside the second movable slot 608. The second sliding frame 6010 is fixedly connected to a second support plate 6015 at the center of the upper end away from the fourth bevel gear 604. The upper center of the second support plate 6015 is rotatably sleeved with a fourth sprocket 6016 through a bearing. An extension plate 6017 is slidably sleeved inside the second sliding frame 6010. The extension plate 6017 is fixedly connected to the fourth connecting plate 601 at one end away from the fourth bevel gear 604. The centers of both sides of the extension plate 6017 are fixedly connected to the second connecting plate 6017. The slide rail 6018, the two second slide rails 6018 are respectively slidably sleeved inside the two second slide grooves 6012, a second fixed block 6019 is fixedly connected to the center side of the upper end of the extension plate 6017 near a section of the fourth bevel gear 604, the extension plate 6017 is slidably sleeved on the outside of the second screw rod 603, the third sprocket 6014 and the fourth sprocket 6016 are sleeved on the outside of the second chain 6020, two chain buckles of the second chain 6020 are respectively fixedly connected to the first fixed block 609 and the second fixed block 6019, a spur gear 6021 is fixedly connected to the upper end of the second transmission shaft 6013, and there is a toothed transmission between the spur gear 6021 and the rack 607.

[0045] Furthermore, when the driving mechanism 7 is activated and drives the fourth bevel gear 604 to start rotating, the power transmission process is immediately started. Since the fourth bevel gear 604 is fixedly connected to one side of the second screw rod 603, the second screw rod 603 will rotate synchronously with the rotation of the fourth bevel gear 604. The outer side of the second screw rod 603 adopts a threaded design, and this threaded part forms a threaded sleeve relationship with the inside of the second slide frame 6010. This design ensures that when the second screw rod 603 rotates, the second slide frame 6010 can move stably in a straight line along the first slide groove 605 preset inside the first slide frame 602. This movement is The precise control of the threaded connection ensures the accuracy and stability of the movement. As the second sliding frame 6010 moves, the second transmission shaft 6013 and the third sprocket 6014 on the upper end center of which is close to the fourth bevel gear 604 also move synchronously. The upper end of the second transmission shaft 6013 is fixedly connected to a spur gear 6021, and a toothed transmission relationship is formed between the spur gear 6021 and the rack 607 at the upper end of the protective cover 606. When the spur gear 6021 drives the third sprocket 6014 to rotate, the third sprocket 6014 is constrained by the second chain 6020, thereby synchronously pushing out the extension plate 6017, thereby completing the telescopic movement.

[0046] In the preferred technical solution of this embodiment, please refer to Fig.11 As shown, the driving mechanism 7 includes a mounting cover 701 fixedly connected to the upper ends of the two protective covers 606, a support frame 702 is fixedly connected to the center of the upper end of the mounting cover 701, a second motor 703 is fixedly connected to the upper end of the support frame 702, two second ear pieces 704 are fixedly connected to the diagonal positions on both sides of the mounting cover 701, and the insides of the two second ear pieces 704 are both rotatably sleeved with third transmission shafts 705 through bearings, and the lower ends of the two third transmission shafts 705 are fixedly connected to fifth bevel gears 706, and the fifth bevel gear 706 and the fourth bevel gear 603 are fixedly connected to the lower ends of the two third transmission shafts 705. 04 is a gear meshing transmission, and the fifth bevel gear 706 and the fourth bevel gear 604 on the other side are gear meshing transmission, the upper ends of the two third transmission shafts 705 are fixedly connected with the second transmission wheel 707, and the output end of the second motor 703 is arranged and fixedly connected with two third driving wheels 708, and the third driving wheel 708 at the upper end and the outer side of the second transmission wheel 707 at one side are provided with a third transmission belt 709, and the outer side of the third driving wheel 708 at the lower end and the outer side of the second transmission wheel 707 at the other side are provided with a fourth transmission belt 7010.

[0047] Furthermore, when the second motor 703 is started, its output end starts to rotate, and two third driving wheels 708 are fixedly connected to the output end of the second motor 703. The two third driving wheels 708 rotate synchronously with the rotation of the second motor 703. The two third driving wheels 708 are connected to the two second transmission wheels 707 through the third transmission belt 709 and the fourth transmission belt 7010 respectively. The third driving wheel 708 at the top is connected to the second transmission wheel 707 at one side through the third transmission belt 709, and the third driving wheel 708 at the bottom is connected to the second transmission wheel 707 at the other side through the fourth transmission belt 7010. The two second transmission wheels 707 are fixedly connected to the upper ends of the two third transmission shafts 705 respectively. Therefore, when the third driving wheel 708 drives the second transmission wheel 707 to rotate through the transmission belt, the third transmission shaft 705 will also rotate accordingly. The lower end of each third transmission shaft 705 is fixedly connected with a fifth bevel gear 7 06. Due to the rotation of the third transmission shaft 705, the fifth bevel gear 706 will also rotate synchronously. The two fifth bevel gears 706 respectively form a gear meshing transmission relationship with the fourth bevel gears 604 in the two extension mechanisms 6. Therefore, when the fifth bevel gear 706 rotates, it will transmit power to the fourth bevel gear 604 through gear meshing, thereby driving the fourth bevel gear 604 and the second screw rod 603 connected to it to rotate. The rotation of the second screw rod 603 will drive the second sliding frame 6010 to move inside the first sliding frame 602, thereby triggering the extension or contraction action of the extension mechanism 6. The working principle of the driving mechanism 7 is mainly driven by the second motor 703, and the power is transmitted to the second transmission wheel 707 by the transmission belt, thereby driving the third transmission shaft 705 and the fifth bevel gear 706 to rotate. The fifth bevel gear 706 transmits power to the fourth bevel gear 604 in the extension mechanism 6 through gear meshing, and finally drives the extension mechanism 6 to extend or contract.

[0048] In the preferred technical solution of this embodiment, please refer to Fig.13 As shown, the second positioning and clamping mechanism 8 includes a connecting column 801, which is fixedly connected to one side of the center of the lower end of the fourth connecting plate 601, and the lower end of the connecting column 801 is fixedly connected to the third support plate 802, and three sliding rods 803 are arranged in a sliding sleeve at the center of the inside of the third support plate 802, and one end of the three sliding rods 803 is fixedly connected to a connecting strip 804, and the fifth connecting plate 805 is fixedly connected to the center of the upper and lower sides of the connecting strip 804, and the outer sides of the three sliding rods 803 are all slidably sleeved with springs 806, and the two ends of the three springs 806 are respectively abutted against each other between the connecting strip 804 and the third support plate 802, and the three sliding rods 803 are fixedly connected to a limiting buckle 807 at one end away from the connecting strip 804, and a pulley 808 is rotatably connected between the two fifth connecting plates 805.

[0049] Furthermore, the second positioning and clamping mechanism 8 is mainly connected to the fourth connecting plate 601 in the extension mechanism 6 through the connecting column 801, so as to ensure that the clamping mechanism can move with the extension or contraction of the extension mechanism 6. When the extension mechanism 6 is in the extended state, the connecting column 801 drives the third support plate 802 to move together. At this time, the three slide bars 803 arranged in a sliding sleeve at the center of the third support plate 802 also move accordingly. One end of the three slide bars 803 is connected by a connecting strip 804 to form an integral sliding assembly. On the outer side of the slide bar 803, the sliding sleeve is provided with a spring 806. The two ends of these springs 806 are respectively abutted against each other between the connecting strip 804 and the third support plate 802, providing a certain elasticity and reset force for the sliding of the slide bar 803. When an object needs to be clamped, the external force will push the connecting strip 804 to ... The strip 804 moves toward the third support plate 802, thereby driving the slide bar 803 to slide inside the third support plate 802. At this time, the spring 806 will be compressed to store elastic potential energy. As the connecting strip 804 moves, the pulley 808 between the two fifth connecting plates 805 will also move accordingly. The design of the pulley 808 enables the clamping mechanism to contact and fit the surface of the object more smoothly when clamping the object, thereby increasing the stability and reliability of the clamping. When the external force disappears, the spring 806 will release the stored elastic potential energy, pushing the connecting strip 804 and the slide bar 803 to move in opposite directions until the limit buckle 807 contacts the third support plate 802 or the surface of the object to achieve the clamping effect. The design of the limit buckle 807 prevents the slide bar 803 from excessive sliding, thereby ensuring the stability and safety of the clamping mechanism during the clamping process.
