Description

Technical Field

[0001] This invention relates to the field of welding processing technology, specifically to a sheet metal fixing welding machine. Background Technology

[0002] Sheet metal parts are characterized by their light weight, high strength, electrical conductivity, low cost, and good mass production performance, and are widely used in electronics, communications, automotive, and medical device industries. After initial processing, sheet metal parts need to be assembled and connected, often using welding to securely connect different parts.

[0003] Existing sheet metal welding equipment requires positioning fixtures and other components to adjust and position the sheet metal parts to be welded during processing. For example, a sheet metal welding device with patent publication number CN220278684U mainly includes a base, a placement plate, and a first sliding plate. The first sliding plate is equipped with a mounting frame, a welding equipment body, and a welding head. The placement plate is equipped with a third sliding plate, a threaded rod, and a positioning pressure plate. The positioning pressure plate moves when the threaded rod is rotated, thereby achieving the positioning operation of the sheet metal parts. Then, the moving welding head performs welding processing on the sheet metal parts.

[0004] However, the loading, unloading, and positioning operations of the above-mentioned equipment are all done manually. The positioning operation is cumbersome and inefficient. In addition, it can only be used to position two horizontal sheet metal parts and cannot be used to process two sheet metal parts with a certain angle, thus its application range is narrow.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to the accompanying drawings. This invention provides a technical solution: A sheet metal part fixing welding machine includes a worktable 100 with a rectangular groove inside, side plates 101 symmetrically fixed on both sides of the top of the worktable 100, a sheet metal conveying mechanism disposed between the two side plates 101, and a welding mechanism disposed above the middle of the worktable 100. The rectangular groove of the workbench 100 is provided with a support and limiting component. The plate conveying mechanism is distributed on both sides of the support and limiting component. The support and limiting component includes a fixed support structure and a lifting limiting structure. The inner sides of the two side plates 101 are provided with baffle structures corresponding to the lifting limiting structure. The welding mechanism includes rotating components symmetrically arranged on both sides of the top of the workbench 100, a moving component connected between the tops of the two rotating components, a welding component disposed at the bottom of the moving component, and a cooling component located on both sides of the bottom of the welding component. The cooling component includes an air-cooled structure and a water-cooled structure. An adjustable feeding mechanism is provided above the workbench 100 at the rear position corresponding to the welding mechanism. The adjustable feeding mechanism includes two guide sliding components, a first angle adjustment component disposed inside the guide sliding components, a second angle adjustment component located on top of the first angle adjustment component, and a positioning component located between the two second angle adjustment components. A top material component is provided below the positioning component.

[0037] During the welding process of sheet metal parts, one main sheet metal part is intermittently conveyed along a straight line by a sheet metal conveying mechanism, while the other auxiliary sheet metal part is fed by an adjustable feeding mechanism. The auxiliary sheet metal part is then positioned in the middle of the worktable 100 and the welding positions are brought into contact with each other. The welding is then performed by the welding mechanism. After the welding process is completed, the welding position is cooled. At the same time, the adjustable feeding mechanism continues to feed and position the sheet metal part. After cooling is completed, the sheet metal part is conveyed and unloaded by the intermittent movement of the sheet metal conveying mechanism. Meanwhile, the other main sheet metal part is fed to the welding mechanism and cooperates with the feeding of the adjustable feeding mechanism to perform the next welding process.

[0038] This invention integrates functions such as plate conveying, support and limiting, multi-directional welding, dual-mode cooling and adjustable feeding into one unit, reducing equipment footprint and process connection time, and facilitating continuous operation. The welding machine of the present invention can realize feeding through different paths. By using the intermittent movement of the plate conveying mechanism and the parallel operation of the adjustable feeding mechanism, the loading and unloading operations are faster and more convenient. Furthermore, while a workpiece is being welded and cooled, the auxiliary sheet metal parts can be loaded and positioned simultaneously on the adjustable feeding mechanism, making the processing flow more concentrated, reducing equipment idle time, and significantly improving production efficiency.

[0039] When the main sheet metal part on the sheet metal conveying mechanism moves to the middle position of the worktable 100, it comes into contact with the fixed support structure, which improves the positional stability of the main sheet metal part when it is conveyed. The lifting limit structure moves it upward and cooperates with the baffle structure to clamp and fix the main sheet metal part, thereby realizing the positioning operation of the main sheet metal part.

[0040] After the adjustable feeding mechanism completes the feeding and positioning of the sub-sheet metal parts, it can use the first angle adjustment component to make its upper structure drive the sub-sheet metal parts to rotate to the middle of the worktable 100, so that the sub-sheet metal parts change from a vertical state to a horizontal state, and adjust their position to correspond with the position of the main sheet metal parts on the sheet metal conveying mechanism, and the welding positions are in contact with each other. At this time, the welding mechanism is located directly above the workbench 100, and the welding component is moved laterally along the upper part of the workbench 100 by the moving component to weld the two horizontal sheet metal parts. After the welding process is completed, the cooling component is used to select air cooling or water cooling.

[0041] When there is a certain angle between the secondary sheet metal part and the main sheet metal part, the second angle adjustment component adjusts the angle between the positioning component and the secondary sheet metal part. Through the cooperation of the guide sliding component, the first angle adjustment component and the second angle adjustment component, the welding edge of the secondary sheet metal part with a certain tilt angle contacts the welding position on the main sheet metal part. The angle of the welding component is adjusted by the rotation component to make it tilted and adapt to the angle between the two sheet metal parts. Then it moves laterally to complete the welding operation.

[0042] Therefore, the main sheet metal part of the present invention is automatically positioned and clamped through conveying, supporting and lifting. The secondary sheet metal part is flipped from vertical to horizontal through the first angle adjustment component. The spatial angle and position of the secondary sheet metal part can be precisely adjusted through the second angle adjustment component and the guide sliding component to match the main sheet metal part. The rotating component and moving component of the welding mechanism can flexibly adjust the welding gun angle and travel path to adapt to the welding requirements of different angle joints and enhance process adaptability.

[0043] The cooling assembly of the present invention includes an air-cooled structure and a water-cooled structure. The cooling method can be selected according to the material characteristics and the requirements of the welding heat-affected zone, effectively controlling deformation and improving the weld microstructure and properties, thereby improving the welding quality. Air cooling can achieve rapid cooling and reduce oxidation, while water cooling can achieve powerful cooling and control deformation, thus providing a wider process window.

[0044] This invention, through guide sliding, two-stage angle adjustment and positioning components, and top material assembly, can adapt to the feeding needs of sheet metal parts of different sizes, shapes and tilt angles, significantly improving the equipment's versatility and flexible production capabilities. The various mechanisms and components of this invention work together to reduce manual handling, positioning, and adjustment, which helps to achieve semi-automation or automation of the welding process, improves production efficiency and reduces labor intensity. It is suitable for welding production scenarios of multiple varieties, small batches or medium batches of sheet metal parts, and can effectively improve welding quality and production efficiency.

[0045] Example 2: The structure of this example is basically the same as that of Example 1, except that the guide sliding assembly includes a guide slide 600 disposed on the top of the side plate 101. A guide groove 601 is provided in the middle of the bottom of the guide slide 600, and the top of the side plate 101 is slidably connected to the guide groove 601. A fixed horizontal shaft 603 is vertically fixed on the inner side of the guide slide 600. A connecting seat 604 is fixed between the two fixed horizontal shafts 603. Multiple teeth are evenly fixed on the top of the guide slide 600 along the length direction, and a guide gear 602 is engaged with the teeth. A motor frame is fixed at a corresponding position on the outer side of the side plate 101. A motor is fixed on the motor frame, and the output shaft of the motor is fixed to the guide gear 602.

[0046] This invention employs a guide gear 602 and teeth to achieve precise displacement control and repeatable positioning of the positioning components and sheet metal parts. The side plate 101 and guide groove 601 provide basic support and guidance to ensure the linear accuracy of the movement. When movement is required, the guide gear 602 is driven to rotate by a motor. Then, through the action of the guide gear 602 and teeth, the guide slide 600 slides along the top of the side plate 101, driving the structure and sheet metal parts on it to move, so that the sheet metal parts are in the appropriate position and contact another sheet metal part for subsequent welding processing.

[0047] The first angle adjustment assembly includes a rotating cylinder 801 rotatably connected to a fixed horizontal shaft 603. A positioning rotating frame 800 and a transmission gear ring 802 are fixed on the rotating cylinder 801. A transmission gear 606 meshes with the top of the transmission gear ring 802. A drive shaft 605 is fixed at the center of the two transmission gears 606. The drive shaft 605 is rotatably connected to the top of the connecting seat 604. A first drive bevel gear 607 is fixed in the middle of the drive shaft 605. A second drive bevel gear 608 meshes with one side of the first drive bevel gear 607. A motor is connected to the second drive bevel gear 608. The motor is fixed to the top of the connecting seat 604. The second angle adjustment component includes an end shaft 707 that is vertically set and rotatably connected to the top of the positioning rotating frame 800. An L-shaped plate 706 is fixed to the inner end of the end shaft 707, and the two L-shaped plates 706 are respectively connected to the two ends of the positioning component through a movable hydraulic rod 705. Multiple teeth are evenly fixed on the outer side wall of the end shaft 707 along the circumferential direction, and a vertical rack 708 is engaged by the teeth. The bottom end of the rack 708 is connected to the outer side wall of the positioning rotating frame 800 through a pushing hydraulic rod 709.

[0048] When the sheet metal part is loaded and positioned, the motor on the connecting seat 604 drives the first drive bevel gear 607 and the second drive bevel gear 608 to rotate the rotating cylinder 801 towards the welding mechanism, thereby rotating the sheet metal part to the welding mechanism. The moving hydraulic rod 705 causes the positioning component to move the sheet metal part, so that the sheet metal part contacts the sheet metal part on the conveying mechanism for subsequent welding processing. If it is necessary to adjust the angle of the sheet metal part on the positioning component relative to the sheet metal part on the conveying mechanism, the hydraulic rod 709 is pushed to drive the rack 708 to move. Under the action of its upper teeth and the rack 708, the end shaft 707 drives the L-shaped plate 706 and the positioning component to rotate, thereby adjusting the angle of the sheet metal part in the positioning component.

[0049] The positioning assembly includes a rectangular plate positioning groove 700 fixed to the front ends of two movable hydraulic rods 705. The top and bottom ends of the plate positioning groove 700 are both open. A vertical positioning pressure plate 701 is provided in the plate positioning groove 700. The top end of the positioning pressure plate 701 is inclined to the rear side. Multiple springs are evenly connected between the rear side of the positioning pressure plate 701 and the inner side wall of the plate positioning groove 700. Multiple guide shafts 702 are also evenly fixed on the rear side of the positioning pressure plate 701. One end of the guide shaft 702 extends out of the plate positioning groove 700 and is slidably connected to the side wall of the plate positioning groove 700. A positioning hydraulic rod 703 is fixed in the middle of the rear side of the plate positioning groove 700. The front end of the positioning hydraulic rod 703 extends into the plate positioning groove 700 and is fixed with a positioning pusher 704. The positioning pusher 704 is in corresponding contact with the positioning pressure plate 701.

[0050] When loading sheet metal parts, they are inserted between the positioning plate 701 and the front wall of the sheet metal positioning groove 700. The positioning plate 701 elastically positions the sheet metal parts under the action of the spring, and the bottom end of the sheet metal parts contacts the top of the top material assembly, with the side to be welded facing upward. Then, the positioning hydraulic rod 703 is activated, which drives the positioning pusher 704 to move forward, so that the positioning pusher 704 presses tightly on the positioning plate 701, thereby fixing the position of the sheet metal parts and realizing the positioning operation.

[0051] The top-feeding assembly includes a spring groove 803 disposed on the inner wall of the positioning rotating frame 800. A limiting horizontal plate 804 is slidably connected between the two spring grooves 803, and the end of the limiting horizontal plate 804 is located in the spring groove 803 and connected to the inner end of the spring groove 803 by a spring. Two limiting slide grooves are symmetrically provided at the bottom of the limiting horizontal plate 804, and a limiting slider 807 is slidably connected thereto. The limiting slide grooves and the limiting slider 807 are T-shaped or dovetail-shaped. A hinge rod 806 is rotatably connected to the bottom of the limiting slider 807. The two hinge rods 806 are arranged crosswise and are hinged to each other in the middle. A top-feeding hydraulic rod 805 is horizontally fixed on the lower inner side of the positioning rotating frame 800, and the ends of the two top-feeding hydraulic rods 805 are rotatably connected to the bottom ends of the corresponding hinge rods 806.

[0052] When adjusting the position of the sheet metal part relative to the positioning assembly, the extension or shortening of the top hydraulic rods 805 on both sides drives the bottom end of the hinge rod 806 to move, causing the bottom ends of the two hinge rods 806 to move closer or further apart and rotate relative to each other. This causes the limiting slider 807 at its top to move relative to the limiting horizontal plate 804, while simultaneously driving the limiting horizontal plate 804 to move up and down, adjusting its height position, and thus adjusting the position of the sheet metal part during positioning.

[0053] Example 3: The structure of this example is basically the same as that of Example 1, except that the rotating assembly includes a rotating column 301 rotatably connected to the top of the workbench 100 and perpendicular to the side plate 101. A welding rotating frame 300 is fixed on the rotating column 301, and the moving assembly is located on the top of the two welding rotating frames 300. An inclined rotating hydraulic rod 302 is rotatably connected to one side of the welding rotating frame 300, and the bottom end of the rotating hydraulic rod 302 is rotatably connected to the top surface of the workbench 100. Two parallel fixed sliding shafts 303 are fixed between the upper parts of the two welding rotating frames 300, and the welding assembly and the cooling assembly are arranged on the fixed sliding shafts 303.

[0054] When the angle of the welding mechanism needs to be adjusted, the extension or retraction of the hydraulic rod 302 is rotated to drive the welding rotating frame 300 and the rotating column 301 to rotate, thereby driving the moving components and welding components on them to rotate, adjusting the tilt angle of the welding components relative to the welding position of the sheet metal parts so as to adapt to two sheet metal parts with different included angles; the fixed shaft on it is used to install the cooling components and to provide guidance for the movement of the welding components.

[0055] The movable assembly includes a welding top plate 400 fixed to two welding top ends. A movable screw 401 is rotatably connected to the top of the welding top plate 400. A motor is connected to one end of the movable screw 401 and the motor is fixed to the top surface of the welding top plate 400. A movable seat 402 is threadedly connected to the movable screw 401. The bottom surface of the movable seat 402 is slidably connected to the welding top plate 400. Movable frames 403 are symmetrically fixed at both ends of the movable seat 402. A slot is provided on the welding top plate 400 corresponding to the position of the movable frame 403. The bottom end of the movable frame 403 passes through the slot and is connected to the welding assembly. During welding, the moving screw 401 is driven by a motor to rotate, causing the moving seat 402 and the moving frame 403 to move laterally above the worktable 100 under the drive of the moving screw 401, and the sheet metal parts are welded during the movement.

[0056] The welding assembly includes a sliding seat 404 fixed to the bottom of the movable frame 403. The two ends of the sliding seat 404 are slidably connected to two fixed sliding shafts 303. The sliding seat 404 is provided with an adjusting hydraulic rod 405. The bottom ends of the two adjusting hydraulic rods 405 are jointly fixed with an adjusting plate 406. The adjusting plate 406 is provided with a welding device 407, and the bottom of the welding device 407 is connected to a welding head 408.

[0057] When the moving component moves, the sliding seat 404 drives the welding device 407 and other structures to move accordingly. By adjusting the hydraulic rod 405, the adjusting plate 406 drives the welding device 407 and welding head 408 to extend and retract, so that they can approach the sheet metal part during welding and return to their original position away from the sheet metal part after the welding is completed, so as to obstruct the feeding and position adjustment of the next two sheet metal parts.

[0058] The cooling assembly includes two symmetrically arranged X-shaped tube racks 304, with the top of the tube racks 304 fixedly connected to two fixed sliding shafts 303. The air-cooling structure and the water-cooling structure are arranged on both sides of the bottom of the tube racks 304. The air-cooled structure includes an air-cooled pipe 306 fixed to one side of the bottom of two pipe racks 304. The bottom of the air-cooled pipe 306 is provided with multiple air outlets evenly along the length direction, and the air outlets are inclined towards the welding assembly. A fan 311 is fixed to one side of the bottom of the welding top plate 400. The fan 311 is connected to the top of the air-cooled pipe 306 through a connecting air pipe 310. The water-cooled structure includes a water-cooled pipe 305 fixed to the other side of the bottom of two pipe supports 304. The bottom of the water-cooled pipe 305 is provided with multiple water outlets evenly along the length direction, and the water outlets are inclined towards the welding assembly. A pump body 308 is fixed to the other side of the bottom of the welding top plate 400. The pump body 308 is connected to the top of the water-cooled pipe 305 through a first connecting water pipe 307, and a second connecting water pipe 309 is connected to the other side of the pump body 308. The second connecting water pipe 309 is connected to the bottom of the lifting tank 500.

[0059] When cooling the welding position, air cooling or water cooling should be selected according to the processing requirements; When the air-cooled structure is working, the fan 311 sends air into the air-cooled pipe 306 through the connecting air duct 310 and blows it to the welding position of the sheet metal part through the air outlet. A cooling device or other structure can be installed on the connecting air duct 310 to reduce the airflow temperature and improve the air-cooling effect. When the water-cooled structure is working, cooling water is filled into the lifting tank 500. Through the action of the pump body 308, the cooling water enters the water-cooling pipe 305 along the second connecting water pipe 309 and the first connecting water pipe 307, and is sprayed onto the welding position of the sheet metal part through the water outlet for water cooling treatment. Then the cooling water returns to the lifting tank 500 along the perforated plate 504 to achieve recycling. A multi-stage filtration structure can be set inside the lifting tank 500 to reduce the blockage of the second connecting water pipe 309 and other structures caused by processing waste.

[0060] Example 4: The structure of this example is basically the same as that of Example 1. The difference is that the support limiting component includes a base plate 102 fixed in the middle of the rectangular groove of the workbench 100. The base plate 102 is provided with a lifting slot 103 in the middle. The fixed support structure is symmetrically arranged on the top two sides of the base plate 102. The lifting limiting structure is slidably connected in the lifting slot 103. The fixed support structure includes multiple support rollers 104 rotatably connected to the top center of the base plate 102, and the multiple support rollers 104 are symmetrically arranged on both sides of the lifting groove 500. The lifting limit structure includes a lifting groove 500 slidably connected in the lifting groove 103. Horizontal support plates 501 are symmetrically fixed at both ends of the top of the lifting groove 500, and a perforated plate 504 is fixed on the inner top. A vertical spring shaft 502 is fixed at the bottom of the support plate 501. The bottom end of the spring shaft 502 passes through the base plate 102 and is slidably connected to the base plate 102. Multiple springs are evenly connected between the base plate 102 and the support plate 501. Four vertical lifting hydraulic rods 503 are fixed at the four corners of the base plate 102, and the top ends of the lifting hydraulic rods 503 are fixedly connected to the bottom of the support plate 501 on the corresponding side. The baffle structure includes a baffle 105 that is horizontally slidably connected to the side plate 101. A telescopic screw 107 is rotatably connected to the top of the baffle 105. One end of the telescopic screw 107 is connected to a motor, and the motor is fixed to the top of the baffle 105. A threaded cylinder 106 is fixed at a corresponding position on the side plate 101, and the telescopic screw 107 is threadedly connected to the threaded cylinder 106.

[0061] During the process of the sheet metal part moving from the welding mechanism to the welding mechanism, the bottom of the sheet metal part simultaneously contacts the conveying roller 200 and the support roller 104. The support roller 104 provides support for the sheet metal part, improving its positional stability during the process of passing through the welding mechanism and during welding. When the sheet metal part moves to the bottom of the welding mechanism and is welded, the lifting hydraulic rod 503 moves the support plate 501 and the lifting groove 500 upward to contact the bottom of the sheet metal part and lift it up until both ends of the sheet metal part are pressed tightly against the bottom of the baffle 105 structure by the support plate 501, thereby positioning the sheet metal part. The perforated plate 504 cooperates with the support plate 501 to provide support for the welding position of the sheet metal part and improve positional stability.

[0062] When it is necessary to adjust the position of the two baffle structures according to the width of the sheet metal part, the telescopic screw 107 is driven to rotate by the motor. While the telescopic screw 107 rotates relative to the fixed threaded cylinder 106, it moves relative to the threaded cylinder 106 under the action of the thread, thereby driving the baffle 105 to move and adjusting the distance between the two baffles 105 to adapt to sheet metal parts of different widths.

[0063] Example 5: The structure of this example is basically the same as that of Example 1, except that the plate conveying mechanism includes multiple conveying rollers 200 evenly arranged between two side plates 101. The conveying rollers 200 are distributed on both sides of the support and limiting assembly and are rotatably connected to the side plates 101. One end of each conveying roller 200 is fixed with a worm gear 201. The bottoms of the multiple worm gears 201 are engaged with a worm 202. The worm 202 is rotatably connected to the top of the worktable 100. A first conveying bevel gear 203 is fixed in the middle of the worm 202. A second conveying bevel gear 204 is engaged at the bottom of the first conveying bevel gear 203. The second conveying bevel gear 204 is connected to a motor, and the motor is mounted on the worktable 100.

[0064] When conveying sheet metal sheets, the worm gear 202 is rotated by the drive of the motor and the transmission of the first conveying bevel gear 203 and the second conveying bevel gear 204. Then, through the transmission of the worm gear 202 and multiple worm wheels 201, all the conveying rollers 200 rotate simultaneously to convey the sheet metal parts placed on top of the conveying rollers 200. The sheet metal conveying mechanism works intermittently to convey the sheet metal parts intermittently in order to coordinate with processing operations such as welding.
