Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a linear welding machine. Background Technology

[0002] Currently, during the welding process of PE tanks used for aquaculture, the bottom of the tank needs to have a slope of about 3° due to considerations such as wastewater discharge. The actual slope will be adjusted according to specific circumstances to meet the usage requirements of the aquaculture tanks.

[0003] However, existing welding equipment cannot adjust the angle of the welding platform, making it inconvenient to weld the bottom of sloping aquaculture tanks, thus failing to meet usage requirements. Summary of the Invention

[0004] In order to adjust the angle of the welding platform and improve the applicability of the welding equipment, this application provides a linear welding machine.

[0005] This application provides a linear welding machine, which adopts the following technical solution:

[0006] A linear welding machine includes a welding platform and a gantry frame. The welding platform is disposed below the gantry frame and includes a support plate, multiple vertical rods, and connecting rods. One end of each connecting rod is connected to a vertical rod, and the end of the connecting rod away from the vertical rod is connected to the support plate. The bottom of the support plate is provided with an angle adjustment component for adjusting the angle of the welding platform. An electrical control box is provided inside the gantry frame, and a mounting frame is provided on the gantry frame. The mounting frame is provided with a translation component for controlling its own movement on the gantry frame, and a welding device is provided inside the mounting frame.

[0007] By adopting the above technical solution, the angle of the welding platform can be adjusted by the angle adjustment component before welding, allowing sloping workpieces to be placed on the welding platform for welding, thus improving the applicability of the welding equipment. After the workpiece is placed on the welding platform, the translation component can move the mounting frame on the gantry, thereby moving the welding device on the gantry. This allows the welding device to weld different positions on the workpiece, minimizing multiple welding operations and improving the welding efficiency of the welding device.

[0008] In one specific implementation, the angle adjustment assembly includes a first motor, a worm gear, a worm, a screw, and a lifting cylinder. A placement frame is provided below the support plate. The first motor is mounted on the placement frame. The worm is connected to the output end of the first motor. The worm gear is connected to the worm. The top end of the screw is connected to the lifting cylinder. The screw and the worm are threadedly connected. The lifting cylinder is connected to the support plate. A first vertical plate is provided on the placement frame. A first upper sensor is connected to the first vertical plate. A first lower sensor is connected to the side wall of the lifting cylinder. A first opening is provided on the first vertical plate for the first lower sensor to move.

[0009] By adopting the above technical solution, before welding, the first motor runs, driving the worm gear to rotate, which in turn drives the worm wheel to rotate. Since the screw and worm wheel are threadedly connected, the rotation of the worm wheel can drive the screw to move vertically, thus allowing the lifting cylinder to move vertically. This, in turn, allows the angle of the welding platform to be adjusted, enabling inclined welding parts to be placed on the welding platform, improving the applicability of the welding equipment. When the lifting cylinder moves, it drives the first lower sensor to move as well. The first upper sensor works in conjunction with the first lower sensor; when the distance between them reaches a set value, it can control the first motor to stop running, thereby allowing the welding platform to be adjusted to the corresponding angle.

[0010] In one specific implementation, the translation component includes a traveling motor, a gear, and a guide wheel. The gantry is equipped with a rack, the traveling motor is mounted on the mounting frame, the gear is located at the output end of the traveling motor, the gear is connected to the rack, and the guide wheel is located on the inner wall of the mounting frame and abuts against the gantry.

[0011] By adopting the above technical solution, after the workpiece is placed on the welding platform, the traveling motor runs, driving the gears to rotate. This allows the mounting frame to move along the length of the rack, enabling the welding device to move to different positions on the workpiece for welding, minimizing multiple welding operations and improving the welding efficiency of the welding device. The guide wheels enhance the connection stability between the mounting frame and the gantry, minimizing wobbling of the mounting frame and thus improving its stability during movement.

[0012] In one specific implementation, the welding apparatus includes a welding torch, a moving component for driving the welding torch to move vertically, and a oscillating component for driving the welding torch to oscillate.

[0013] By adopting the above technical solution, the moving component can drive the welding torch to move in the vertical direction, thereby controlling the welding process of the welding torch. The swinging component can drive the welding torch to swing, thereby adjusting the angle of the welding torch so that the welding torch is perpendicular to the surface of the weldment with a slope, which helps to improve the welding effect.

[0014] In one specific implementation, the swing assembly includes a swing plate, a swing motor, a connecting shaft, and a rotating shaft. The rotating shaft is connected to the inner wall of the mounting frame, the swing plate is connected to the rotating shaft, the swing motor is disposed within the mounting frame, the connecting shaft is connected to the output end of the swing motor, the swing plate is provided with a waist hole for the connecting shaft to move, and the end of the connecting shaft is disposed within the waist hole.

[0015] By adopting the above technical solution, when the welding torch moves to the welding position, the oscillating motor runs, driving the connecting shaft to move, thereby enabling the oscillating plate to oscillate around the rotation axis, which in turn drives the oscillation of the welding torch, making the welding torch perpendicular to the surface of the inclined welding part, which helps to improve the welding effect.

[0016] In one specific implementation, the moving component includes a slide table, a slide base, and an electric push rod. The slide table is disposed on the side wall of the swing plate, the electric push rod is disposed on the slide table, the slide base is slidably disposed on the slide table and connected to the output end of the electric push rod, and the slide base is provided with a connecting component for connecting the welding torch.

[0017] By adopting the above technical solution, after the welding torch has finished swinging, the output end of the electric push rod extends, pushing the slide block to slide on the slide table, thereby moving the connecting component and the welding torch toward the welding position for welding. After welding is completed, the output end of the electric push rod retracts, pulling the slide block to slide on the slide table, thereby moving the connecting component and the welding torch away from the welding position.

[0018] In one specific implementation, the connecting assembly includes a first fixing block, a second fixing block, a connecting plate, and a movable rod. The first fixing block is connected to the slide block, the connecting plate is connected to the first fixing block, the movable rod is connected to the connecting plate, the second fixing block is connected to the end of the movable rod away from the connecting plate, the welding torch is connected to the second fixing block, and a fixing plate is connected to the side wall of the connecting plate. A first proximity sensor is provided on the fixing plate.

[0019] By adopting the above technical solution, the arrangement of the first fixed block, the second fixed block, the connecting plate, and the movable rod connects the welding torch to the slide, allowing the slide to move the welding torch. The first proximity sensor detects the distance between the welding torch and the workpiece, thereby controlling the operation of the electric push rod, and further controlling the sliding of the slide on the slide table. This helps improve the accuracy of the welding torch's movement position, thus improving the welding effect.

[0020] In one specific implementation scheme, multiple mounting brackets are provided below the gantry frame, and each mounting bracket is equipped with a second motor. The output end of the second motor is equipped with a lead screw, and a lead screw nut is connected to the lead screw. A mounting plate is connected to the lead screw nut, and multiple crossbars are provided on the mounting plate. Each crossbar is equipped with multiple sets of clamping devices. A second upper sensor is provided on the side wall of the lead screw nut, and a second vertical plate is provided on the mounting bracket. A second lower sensor is provided on the second vertical plate, and a second opening is provided on the second vertical plate for the movement of the second upper sensor.

[0021] By adopting the above technical solution, after the weldment is placed on the welding platform, the second motor operates, driving the lead screw to rotate. This causes the lead screw nut and mounting plate to move along the length of the lead screw, thereby driving the clamping device on the crossbar to clamp the weldment. As the lead screw nut moves along the length of the lead screw, the second upper sensor moves along with it. The second lower sensor cooperates with the second upper sensor. When the distance between the two reaches a set value, it can control the second motor to stop running, thereby allowing the clamping device to move to the corresponding position.

[0022] In one specific implementation, each set of clamping devices includes a clamping plate and multiple sets of adjusting components. Each set of adjusting components includes a connecting rod, a limiting block, and a first spring. The connecting rod passes through the crossbar, and the length of the multiple connecting rods gradually decreases from the middle of the crossbar towards both ends. The limiting block is disposed at the top of the connecting rod, and the clamping plate is connected to the bottom of the multiple connecting rods. The first spring is sleeved on the connecting rod and disposed between the crossbar and the clamping plate.

[0023] By adopting the above technical solution, the clamping plate is movably connected to the horizontal plate through the connecting rod and the limiting block. The setting of the first spring enables the clamping plate to automatically adjust the angle when it is pressed against the welded part, which helps the clamping plate to press the welded parts at different angles and improves the applicability of the clamping device.

[0024] In one specific implementation, two second proximity sensors are provided on the two end sidewalls of the gantry frame, and a first sensor, a second sensor, and a third sensor for detecting the position of the welding torch are provided at intervals on the middle sidewall of the gantry frame, and a center sensor is provided on the sidewall of the mounting frame.

[0025] By adopting the above technical solution, the two second proximity sensors can detect the approach of the mounting frame, thereby controlling the mounting frame and welding torch to stop moving. This helps to limit the movement range of the mounting frame and welding torch, improving the safety of the welding torch during movement. When the mounting frame moves to the corresponding position on the gantry, the settings of the center sensor, first sensor, second sensor, and third sensor help to adjust the angle of the welding torch and switch the slide program, allowing the welding torch to adapt to the surface of the workpiece with a slope, thus improving the welding effect.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting the angle adjustment component, the angle of the welding platform can be adjusted so that the welding platform can be adapted to the sloping welding parts, making it easy for the sloping welding parts to be placed stably on the welding platform, thus improving the applicability of the welding platform;

[0028] 2. By setting up translation and oscillation components, the translation component can move the welding torch to different welding positions, and the oscillation component can adjust the angle of the welding torch, so that the welding angle of the welding torch can be adjusted according to the surface slope of the weldment, which helps to improve the welding effect and improve the applicability of the welding equipment.

[0029] 3. By setting the central sensor, the first sensor, the second sensor, and the third sensor, when the translation component moves the welding torch to different welding positions, the welding torch can adjust its angle and switch the slide program to weld the inclined workpiece. This allows the welding torch to weld different positions of the workpiece sequentially, minimizing the need for welding in two stages due to the large size of the workpiece, and improving the welding efficiency of the welding equipment.

[0039] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0040] This application discloses a linear welding machine, referring to... Figure 1 and Figure 2The system includes a welding platform 1 and a gantry frame 2. An electrical control box 3 is fixedly installed inside the gantry frame 2. The welding platform 1 is fixed below the gantry frame 2. The welding platform 1 includes a support plate 11, multiple vertical rods 12, and connecting rods 13. One end of each connecting rod 13 is hinged to the top of one of the vertical rods 12, and the end of each connecting rod 13 away from the vertical rods 12 is rotatably connected to the top surface of the support plate 11. A placement frame 14 is fixedly installed directly below the support plate 11. An angle adjustment assembly 4 is provided on the placement frame 14. The angle adjustment assembly 4 includes a first motor 41, a worm gear 42, a worm 43, a screw 44, and a lifting cylinder 4. 5. The first motor 41 is fixedly installed on the placement frame 14. The worm gear 43 is fixedly connected to the output end of the first motor 41. The worm wheel 42 is connected to the worm gear 43 for transmission. The top end of the screw 44 is threadedly connected to the lifting cylinder 45. The screw 44 is threadedly connected to the worm wheel 42. The top end of the lifting cylinder 45 is fixedly connected to the bottom surface of the bearing plate 11. The placement frame 14 is fixedly equipped with a first vertical plate 15. The first upper sensor 16 is fixedly connected to the first vertical plate 15. The side wall of the lifting cylinder 45 is fixedly connected with a first lower sensor 17. The first vertical plate 15 has a first opening 18 for the first lower sensor 17 to move.

[0041] Before the workpiece is placed on the welding platform 1, the first motor 41 drives the worm gear 43 to rotate, which in turn drives the worm wheel 42 to rotate. The screw 44 moves vertically under the drive of the worm wheel 42, which in turn drives the lifting cylinder 45 and the bearing plate 11 to move vertically. This, in turn, causes the ends of the multiple connecting rods 13 connected to the bearing plate 11 to move up and down. When the distance between the first upper sensor 16 and the first lower sensor 17 reaches the set value, the electrical control box 3 controls the first motor 41 to stop running. This allows the welding platform 1 to be adjusted to an angle that matches the workpiece, facilitating the placement of the workpiece and improving the applicability of the welding platform 1.

[0042] Reference Figure 1 and Figure 3Two mounting brackets 19 are fixed below the gantry frame 2, and the two mounting brackets 19 are fixed on both sides of the welding platform 1. A second motor 20 is fixed on each mounting bracket 19. A lead screw 21 is fixedly connected to the output end of the second motor 20. A lead screw nut 22 is threaded onto the lead screw 21. A mounting plate 23 is fixedly connected to the side wall of the lead screw nut 22. Two crossbars 24 are fixed on the mounting plate 23. Multiple sets of clamping devices 29 are provided on each crossbar 24. A second upper sensor 25 is fixedly connected to the side wall of the lead screw nut 22. A second vertical plate 26 is fixed on the mounting bracket 19. A second lower sensor 27 is fixedly connected to the second vertical plate 26. A second opening 28 is provided on the second vertical plate 26 for the second upper sensor 25 to move. After the welded parts are placed, the second motor 20 drives the lead screw 21 to rotate, causing the lead screw nut 22 and the mounting plate 23 to move along the length of the lead screw 21. When the distance between the second upper sensor 25 and the second lower sensor 27 reaches the set value, the electrical control box 3 controls the second motor 20 to stop running, causing the clamping device 29 to move to the corresponding position to clamp the welded parts, which helps to improve the stability of the welded parts during the welding process, thereby improving the welding effect.

[0043] Reference Figure 3 and Figure 4 Each set of clamping devices 29 includes a clamping plate 291 and multiple sets of adjusting components 292. Each set of adjusting components 292 includes a connecting rod 2921, a limiting block 2922 and a first spring 2923. The connecting rod 2921 passes through the crossbar 24. The length of the multiple connecting rods 2921 in the multiple sets of adjusting components 292 gradually decreases from the middle of the crossbar 24 toward both ends. The limiting block 2922 is fixed to the top of the connecting rod 2921. The clamping plate 291 is fixedly connected to the bottom of the connecting rod 2921. The first spring 2923 is sleeved on the connecting rod 2921 and located between the crossbar 24 and the clamping plate 291. When the crossbar 24 moves to the corresponding position with the mounting plate 23, the clamping plate 291 can press the surface of the welded part. When the clamping plate 291 is pressed against the welded part, the first spring 2923 can contract to different degrees according to the force on the clamping plate 291, so that the clamping plate 291 can automatically adjust the tilt angle to press the welded part at different angles, thus improving the applicability of the clamping device 29.

[0044] Reference Figure 1 and Figure 5 A mounting frame 5 is movably installed on the gantry frame 2, and a welding device 7 is installed inside the mounting frame 5.

[0045] Reference Figure 5 and Figure 6The welding device 7 includes a welding torch 71, a moving assembly 72 for driving the welding torch 71 to move vertically, and a swing assembly 73 for driving the welding torch 71 to swing. The swing assembly 73 includes a swing plate 731, a swing motor 732, a connecting shaft 733, and a rotating shaft 734. The rotating shaft 734 is rotatably connected to the inner wall of the mounting frame 5. The swing plate 731 is fixedly connected to the rotating shaft 734. The swing motor 732 is fixedly installed inside the mounting frame 5, and the connecting shaft 733 is fixedly connected to the output end of the swing motor 732. The swing plate 731 has two waist holes 735 for the connecting shaft 733 to move, and the ends of both ends of the connecting shaft 733 are located within the two waist holes 735. The movable component 72 includes a slide table 721, a slide base 722, and an electric push rod 723. The slide table 721 is fixed on the side wall of the swing plate 731, the electric push rod 723 is fixed on the top surface of the slide table 721, the slide base 722 is slidably connected to the slide table 721, the output end of the electric push rod 723 is fixedly connected to the slide base 722, and the slide base 722 is provided with a connecting component 8 for connecting the welding torch 71.

[0046] Before welding with the welding torch 71, the oscillating motor 732 operates. The output end of the oscillating motor 732 drives the connecting shaft 733 to move vertically, thereby causing the oscillating plate 731 to oscillate around the rotation shaft 734. This allows adjustment of the angles of the slide table 721 and the slide block 722, and consequently, the angle of the welding torch 71. This allows the welding angle of the welding torch 71 to be adjusted according to the surface slope of the workpiece, improving the welding effect and enhancing its applicability. After the angle of the welding torch 71 is adjusted, the output end of the electric push rod 723 extends, pushing the slide block 722 to slide on the slide table 721. This moves the connecting assembly 8, which in turn moves the welding torch 71 to the welding position for welding. After welding with the welding torch 71, the output end of the electric push rod 723 retracts, pulling the slide block 722 to slide on the slide table 721. This moves the connecting assembly 8, which in turn moves the welding torch 71 away from the welding position to continue subsequent welding.

[0047] Reference Figure 1 and Figure 6The connecting assembly 8 includes a first fixed block 81, a second fixed block 82, a connecting plate 83, and two movable rods 84. The first fixed block 81 is fixedly connected to the side wall of the slide 722, and the connecting plate 83 is fixedly connected to the first fixed block 81 by bolts. The two movable rods 84 are movably connected to the connecting plate 83. The second fixed block 82 is fixedly connected to the end of the two movable rods 84 away from the connecting plate 83. The welding torch 71 is fixedly connected to the side wall of the second fixed block 82. A fixing plate 9 is fixedly fixed to the side wall of the connecting plate 83, and a first proximity sensor 10 is fixedly installed on the fixing plate 9. When the first proximity sensor 10 detects that the distance between the welding torch 71 and the workpiece reaches the welding distance, it can transmit a signal to the electrical control box 3. The electrical control box 3 causes the electric push rod 723 to stop running, so that the welding torch 71 stops exactly at the welding position, which helps to improve the accuracy of the movement position of the welding torch 71, thereby improving the welding effect.

[0048] Reference Figure 5 and Figure 7 A rack 64 is fixed to the top surface of the gantry 2. A translation component 6 is installed on the mounting frame 5. The translation component 6 includes a travel motor 61, a gear 62, and multiple guide wheels 63. The travel motor 61 is fixed to the top surface of the mounting frame 5. The gear 62 is fixedly connected to the output end of the travel motor 61 and meshes with the rack 64. The multiple guide wheels 63 are rotatably connected to the inner wall of the mounting frame 5 and abut against the gantry 2. The operation of the travel motor 61 drives the gear 62 to rotate, thereby causing the guide wheels 63 to roll along the length of the rack 64, which in turn drives the mounting frame 5 and the welding torch 71 to move. This allows the welding torch 71 to weld multiple parts of the workpiece sequentially, minimizing the need for multiple movements of the workpiece due to its large size and improving the welding efficiency of the welding equipment. The guide wheels 63 enable the mounting frame 5 to move smoothly, helping to improve the stability of the mounting frame 5 during movement.

[0049] Reference Figure 1 and Figure 7 Two second proximity sensors 30 are fixedly installed on the side walls at both ends of the gantry frame 2 along its length. When the mounting frame 5 moves on the gantry frame 2, the two second proximity sensors 30 can detect the approach of the mounting frame 5, thereby enabling the electrical control box 3 to control the mounting frame 5 and the welding torch 71 to stop moving. This helps to limit the movement range of the mounting frame 5 and the welding torch 71, and can minimize the risk of the welding torch 71 colliding with the gantry frame 2 during movement and causing damage.

[0050] Reference Figure 7 and Figure 8A first sensor 31, a second sensor 32, and a third sensor 33 are fixedly mounted at intervals on the middle side wall of the gantry frame 2. A center sensor 34 is fixedly mounted on the side wall of the mounting frame 5. The first sensor 31, the second sensor 32, the third sensor 33, and the center sensor 34 are all at the same horizontal height. During the movement of the mounting frame 5, when the center sensor 34 is aligned with the first sensor 31, the second sensor 32, and the third sensor 33 respectively, the angle of the welding torch 71 or the program of the slide table 721 can be adjusted according to the different positions. This makes it easier for the welding torch 71 to weld on the surface of the workpiece with a slope, which helps to improve the welding effect of the welding torch 71.

[0051] The implementation principle of this application embodiment is as follows: The first motor 41 drives the worm gear 43 to rotate, thereby driving the worm wheel 42 to rotate. The screw 44 moves vertically under the drive of the worm wheel 42, thereby driving the lifting cylinder 45 and the bearing plate 11 to move vertically, and then driving the ends of the multiple connecting rods 13 connected to the bearing plate 11 to move up and down. When the distance between the first upper sensor 16 and the first lower sensor 17 reaches the set value, the electrical control box 3 controls the first motor 41 to stop running, so that the welding platform 1 is adjusted to an angle that matches the welding workpiece, which facilitates the placement of the welding workpiece and improves the applicability of the welding platform 1. Before welding with the welding torch 71, the swing motor 732 runs, driving the end of the connecting shaft 733 to move in the waist hole 735, thereby driving the swing plate 731 to swing around the rotation shaft 734 as the axis, adjusting the angle of the welding torch 71, so that the welding angle of the welding torch 71 can be adjusted according to the surface slope of the welding workpiece, which helps to improve the welding effect of the welding torch 71 and improves the applicability of the welding equipment. The running motor 61 drives the gear 62 to rotate, which in turn drives the guide wheel 63 to roll along the length of the rack 64, thereby driving the installation frame 5 and the welding torch 71 to move. This allows the welding torch 71 to weld multiple parts of the workpiece in sequence, minimizing the need to move the workpiece multiple times due to its large size and improving the welding efficiency of the welding equipment.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
