Description

Technical Field

[0001] This invention relates to the field of automatic welding machines for metal pallets, specifically to an automatic welding machine for metal pallets. Background Technology

[0002] Automatic metal pallet welding machines are specialized welding equipment developed for the large-scale and automated production of metal pallets (such as steel pallets, aluminum pallets, galvanized pallets, etc.). Because automatic metal pallet welding machines can automatically weld every seam of a metal pallet, they are a typical intelligent welding workstation in the intelligent manufacturing equipment industry.

[0003] When using existing automatic metal pallet welding machines, double-sided welding of pallets often requires manual disassembly, flipping, and re-clamping, which is cumbersome, involves a large amount of disassembly and assembly work, and seriously reduces the overall welding efficiency of pallets. Meanwhile, existing equipment lacks a dedicated pallet adaptive flipping mechanism, resulting in poor stability and low positioning accuracy during the flipping process, which can easily lead to offset and wobbling, affecting welding quality.

[0004] To address the aforementioned issues, we propose an automated welding machine for metal pallets. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic welding machine for metal pallets. The device is equipped with a flipping component, which, through a crank block and a limiting sliding structure of horizontal and vertical sliders, can drive the pallet frame to rotate stably 180° horizontally. Welding of both sides of the pallet does not require manual disassembly and re-clamping, saving a large number of disassembly and assembly processes, greatly reducing manual workload, and significantly improving the overall processing efficiency of double-sided welding of metal pallets.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic welding machine for metal pallets, comprising a support platform, a support frame fixedly installed on the right side of the top surface of the support platform, a plasma arc welding machine fixedly installed inside the support frame at the top of the support platform, a support groove plate fixedly installed on the left side of the top surface of the support frame, a fixing groove plate slidably installed on the inner wall of the support groove plate, and flipping components provided on both the front and rear sides of the top surface of the fixing groove plate; The flipping assembly includes a horizontal slot plate fixedly installed on one side of the top surface of the fixed slot plate, and a vertical slot plate fixedly installed at the top center of the horizontal slot plate. An extension slot plate is provided on the upper side of the vertical slot plate, and support diagonal rods are fixedly installed on both the left and right sides of the surface of the extension slot plate. A support hole block is fixedly installed on the side of the top surface of the fixed slot plate away from the horizontal slot plate, and a drive longitudinal rod is rotatably installed on the inner wall of the support hole block. A drive gear is fixedly installed at the end of the drive rod away from the transverse slot plate, and a crank block is fixedly installed at the end of the drive rod close to the transverse slot plate. The two corresponding crank blocks are mounted on a tray frame at their opposite ends. A horizontal slider is slidably installed on the inner wall of the transverse slot plate, and a vertical slider is slidably installed on the inner wall of the vertical slot plate. A drive assembly is provided on the top of the support slot plate on one side of the fixed slot plate.

[0007] Furthermore, a control cabinet is provided in front of the support frame, a transverse guide rail is fixedly installed on the top surface of the support frame, a movable longitudinal plate is fixedly installed on the movable part of the transverse guide rail, and the bottom of the movable longitudinal plate is slidably connected to the top surface of the support frame.

[0008] Furthermore, a vertical guide rail is fixedly installed on the left side of the movable longitudinal plate, a longitudinal guide rail is fixedly installed on the movable part of the vertical guide rail, a welding torch is fixedly installed on the movable part of the longitudinal guide rail, and the welding torch is connected to the plasma arc welding machine through a connecting wire harness. The transverse guide rail, the vertical guide rail and the longitudinal guide rail together drive the welding torch to move in three-dimensional space. A pulling component is provided on the surface of the support frame on the right side of the vertical guide rail.

[0009] Furthermore, the pulling assembly includes a pull shell fixedly installed on one side of the support frame surface, and a winding rod is rotatably installed on both the front and rear sides of the inner wall of the pull shell, with a separator ring fixedly installed on each of the front and rear sides of the winding rod wall; Two rotary springs are fixedly installed on the side of the two separator rings near the inner wall of the shell. The ends of the two rotary springs away from the separator rings are fixedly connected to the wall of the winding rod. A pull rope is wound around the middle of the wall of the winding rod.

[0010] Furthermore, an extension opening is provided at the center of the lower side of the inner wall of the pull shell. The opening plate of the extension opening is chamfered. The lower end of the pull rope extends through the extension opening to the outside of the pull shell. A connecting ring is fixedly installed at the lower end of the pull rope. The connecting ring is sleeved on the outer periphery of the welding torch's connecting wire harness. The rotational force of the rotary spring drives the winding rod to wind up the pull rope. The pull rope pulls the connecting wire harness through the connecting ring to avoid the connecting wire harness from tangling and repeated bending.

[0011] Furthermore, the bottoms of the two supporting diagonal rods are fixedly connected to the top surface of the horizontal slot plate, the interior of the vertical slot plate and the horizontal slot plate are interconnected, the extension slot plate is set directly above the vertical slot plate, the interior spaces of the extension slot plate and the vertical slot plate are interconnected, and there is a gap between the extension slot plate and the vertical slot plate.

[0012] Furthermore, placement slots are provided on both the left and right sides of the top surface of the horizontal slot plate. The placement slots are used to provide storage space when the crank block drives the pallet frame to rotate to a horizontal position, so as to ensure the horizontal placement effect of the pallet frame. The gap between the vertical slot plate and the extension slot plate forms the rotation channel of the crank block.

[0013] Furthermore, both the vertical slider and the horizontal slider are rotatably connected to the pallet frame. The vertical slider is located at the center of the pallet frame, and the horizontal slider is located at the end of the pallet frame. The rotatable connection position of the crank block is located between the horizontal slider and the vertical slider. The length of the vertical slider is greater than the interval between the vertical groove plate and the extension groove plate to ensure the sliding stability of the vertical slider. The length of the horizontal slider is greater than the width of the vertical groove plate to ensure the sliding stability of the horizontal slider. When the crank block rotates, under the limiting action of the vertical slider and the horizontal slider, the pallet frame rotates horizontally around the vertical slider, so that it is not necessary to disassemble and reassemble when welding the two sides of the pallet on the pallet frame, thereby improving welding efficiency.

[0014] Furthermore, the drive assembly includes two drive telescopic rods embedded in the top of the support slot plate. The output ends of the two drive telescopic rods are jointly fixedly mounted with a drive gear plate, which is located below the power gear and in the same vertical plane as the power gear. When the drive telescopic rod extends, the power gear meshes with the drive gear plate, driving the power gear to rotate. When the drive telescopic rod retracts, the power gear disengages from the drive gear plate and remains stationary. A foot switch is provided on the left side of the support platform, which is electrically connected to the drive telescopic rod and used to control the extension and retraction of the drive telescopic rod.

[0015] Furthermore, several fixing plates are fixedly installed on the periphery of the top surface of the pallet frame by bolts, and a support frame is fixedly installed on the lower side of the inner wall of the pallet frame. The fixing plates are used to fix the pallet structure to be welded, and the support frame is used to support the pallet structure to be welded, and the support frame does not obstruct the welding position.

[0016] Compared with the prior art, the present invention provides an automatic welding machine for metal pallets, which has the following advantages: 1. The device is equipped with a flipping component. Through the crank block and the limiting sliding structure of the horizontal and vertical sliders, the pallet frame can be driven to flip horizontally 180° stably. The welding of the front and back sides of the pallet does not require manual disassembly and re-clamping, saving a lot of disassembly and assembly processes, greatly reducing the amount of manual labor, and significantly improving the overall processing efficiency of double-sided welding of metal pallets.

[0017] 2. This device relies on multiple limiting constraints of horizontal slot plates, vertical slot plates, and extension slot plates. The horizontal and vertical sliders can only slide along the preset trajectory. Combined with the storage and positioning function of the placement slot, the pallet frame can maintain a horizontal and stable state after flipping, without deviation or shaking. At the same time, the design of the long and short slider structure further improves the sliding stability, effectively ensuring the positioning accuracy during pallet welding and improving the welding quality of the finished product.

[0018] 3. The device is equipped with a pulling component that utilizes the elastic rewinding characteristics of a rotary spring. Combined with the linkage structure of the winding rod, pull rope, and connecting ring, it can adaptively extend and rewind the wire harness as the welding torch moves in three dimensions. It constrains the movement trajectory of the connecting wire harness throughout the process, avoiding problems such as wire harness pulling, repeated bending, and tangling during the movement of the welding torch, reducing the probability of wire harness damage, and reducing equipment failure and subsequent maintenance costs.

[0019] 4. The device adopts a drive structure consisting of a drive telescopic rod, a drive toothed plate, and a power gear. When extended, it engages to achieve a flipping drive, and when retracted, it automatically disengages and goes into standby mode. It does not require the motor to be continuously powered, effectively reducing standby energy consumption and improving energy efficiency.

[0020] 5. The fixing slot plate of the device can be slid out along the support slot plate as a whole, which makes it convenient for operators to pick up, put down and clamp the pallet. With the cooperation of the fixing pressure plate and the support frame, the positioning support structure can not only firmly fix the pallet to be welded, but also not block the welding operation area, thus taking into account both clamping stability and welding operation convenience.

A pulling component 4 is provided on the surface of the support frame 2 on the right side of the vertical guide rail 104. The pulling assembly 4 includes a pull shell 401 fixedly installed on one side of the surface of the support frame 2.

The front and rear sides of the winding rod 402 are each fixedly installed with a separator ring 403. Two rotary springs 404 are fixedly installed on the side of the surface of the two separator rings 403 near the inner wall of the pull shell 401. The ends of the two rotary springs 404 away from the separator rings 403 are fixedly connected to the rod wall of the winding rod 402. A pull rope 405 is wound around the middle of the rod wall of the winding rod 402. An extension opening 406 is provided at the center of the lower side of the inner wall of the pull shell 401. The opening plate of the extension opening 406 is chamfered. The lower end of the pull rope 405 extends through the extension opening 406 to the outside of the pull shell 401. A connecting ring 407 is fixedly installed at the lower end of the pull rope 405. The connecting ring 407 is sleeved on the outer periphery of the connecting wire harness of the welding torch 106. The rotational force of the rotary spring 404 drives the winding rod 402 to wind up the pull rope 405. The pull rope 405 pulls the connecting wire harness through the connecting ring 407 to avoid the connecting wire harness from tangling and repeated bending.

[0025] A plasma arc welding machine 3 is fixedly installed inside the support frame 2 at the top of the support platform 1, while a support groove plate 5 is fixedly installed on the left side of the top surface of the support frame 2. A fixed groove plate 6 is slidably installed on the inner wall of the support groove plate 5, and a flipping component 7 is provided on both the front and rear sides of the top surface of the fixed groove plate 6. The flipping assembly 7 includes a horizontal slot plate 701 fixedly installed on one side of the top surface of the fixed slot plate 6, and a vertical slot plate 702 fixedly installed at the top center of the horizontal slot plate 701. An extension slot plate 703 is provided on the upper side of the vertical slot plate 702. The bottoms of two supporting diagonal rods 704 are fixedly connected to the top surface of the horizontal slot plate 701. The interiors of the vertical slot plate 702 and the horizontal slot plate 701 are interconnected. The extension slot plate 703 is located directly above the vertical slot plate 702. The interior spaces of the extension slot plate 703 and the vertical slot plate 702 are interconnected, and there is a gap between the extension slot plate 703 and the vertical slot plate 702. Supporting diagonal rods 704 are fixedly installed on both the left and right sides of the surface of the extension slot plate 703. A supporting hole block 705 is fixedly installed on the side of the top surface of the fixed slot plate 6 away from the horizontal slot plate 701. A drive longitudinal rod 706 is rotatably installed on the inner wall of the supporting hole block 705. A drive gear 707 is fixedly installed at the end of the drive rod 706 away from the transverse slot plate 701, while a crank block 708 is fixedly installed at the end of the drive rod 706 close to the transverse slot plate 701. The two corresponding crank blocks 708 are rotatably mounted on the opposite ends. Placement slots 7011 are provided on both the left and right sides of the top surface of the transverse slot plate 701. The placement slots 7011 are used to provide storage space when the crank block 708 drives the tray frame 709 to rotate to a horizontal position, so as to ensure the horizontal placement effect of the tray frame 709. The gap between the vertical slot plate 702 and the extension slot plate 703 forms the rotation channel of the crank block 708. A horizontal slider 710 is slidably installed on the inner wall of the transverse slot plate 701, and a vertical slider 711 is slidably installed on the inner wall of the vertical slot plate 702. Both the vertical slider 711 and the horizontal slider 710 are rotatably connected to the pallet frame 709. The vertical slider 711 is located at the center of the pallet frame 709, and the horizontal slider 710 is located at the end of the pallet frame 709. The rotatable connection position of the crank block 708 is located between the horizontal slider 710 and the vertical slider 711. The length of the vertical slider 711 is greater than the interval between the vertical slot plate 702 and the extension slot plate 703 to ensure the sliding stability of the vertical slider 711. The length of the horizontal slider 710 is greater than the width of the vertical slot plate 702 to ensure the sliding stability of the horizontal slider 710. When the crank block 708 rotates, under the limiting action of the vertical slider 711 and the horizontal slider 710, the pallet frame 709 rotates horizontally around the vertical slider 711. This allows for welding on both sides of the pallet on the pallet frame 709 without the need for disassembly and reassembly, thus improving welding efficiency. Combined with appendix Figure 10 The specific process of the pallet frame 709 flipping force is as follows: When the crank block 708 rotates, it generates a rotational torque M2. Under the limiting constraint of the vertical slot plate 702, the extension slot plate 703 and the horizontal slot plate 701, the rotational freedom of the horizontal slider 710 and the vertical slider 711 is restricted, and they can only achieve controlled sliding along the preset straight line direction.

[0026] Driven by the rotational torque M2, the vertical slider 711 slides upward in a straight line, outputting a vertically upward force F1. At the same time, the horizontal slider 710 slides horizontally along the guide rail of the horizontal slot plate 701, outputting a horizontal force F2 to the left. The rotational torque M2 serves as the rotational input of the mechanism. After the mechanism's motion transformation, it generates two sets of linear output forces: a vertically upward force F1 and a horizontal force F2 to the left. F1 and F2 are both output forces from which the mechanism performs work. According to the principle of action and reaction, the load will exert a reaction force on the mechanism that is equal in magnitude and opposite in direction. F1 pushes the load upward, and the load exerts a downward reaction force on the mechanism; F2 pushes the load to the left, and the load exerts a reaction force to the right on the mechanism.

[0027] Both sets of reaction forces are transmitted to the pallet frame 709. The connection position of the horizontal slider 710 is used as the hinge fulcrum of the pallet frame 709. The two sets of reaction forces form opposite stress arms respectively. The torques are superimposed on each other, causing the upper overall mechanism to generate a counterclockwise flipping torque M1 relative to the pallet frame 709. The overturning moment M1 is a secondary overturning moment induced by the load reaction force, not the active driving moment of the mechanism. During the operation of the mechanism, the pallet frame 709 needs to bear the overturning moment M1, so the structural rigidity of the pallet frame 709 can withstand the operation of the structure. A drive assembly 8 is provided on the top of the support slot plate 5, located on one side of the fixed slot plate 6. The drive assembly 8 includes two drive telescopic rods 801 embedded in the top of the support slot plate 5. The output ends of the two drive telescopic rods 801 are fixedly mounted with a drive gear plate 802. The drive gear plate 802 is located below the power gear 707 and is in the same vertical plane as the power gear 707. When the drive telescopic rod 801 extends, the power gear 707 meshes with the drive gear plate 802, driving the power gear 707 to rotate. When the drive telescopic rod 801 retracts, the power gear 707 disengages from the drive gear plate 802 and remains stationary. A foot switch 803 is provided on the left side of the support platform 1. The foot switch 803 is electrically connected to the drive telescopic rod 801 and is used to control the extension and retraction of the drive telescopic rod 801. Several fixing plates 9 are fixedly installed on the periphery of the top surface of the pallet frame 709 by bolts. A support frame 10 is fixedly installed on the lower side of the inner wall of the pallet frame 709. The fixing plates 9 are used to fix the pallet structure to be welded, and the support frame 10 is used to support the pallet structure to be welded, and the support frame 10 does not obstruct the welding position.

[0028] The technical features that distinguish this device from existing technologies are as follows: The drive gear plate 802 is located below the power gear 707. When the drive telescopic rod 801 extends, it engages and flips, and when it retracts, it disengages. The foot switch 803 controls it as needed, reducing energy consumption. The fixed groove plate 6 is slidably installed on the support groove plate 5 and can be pulled out as a whole for clamping, making operation convenient; The tray frame 709 rotates horizontally around the central vertical slider 711, and the horizontal slider 710 limits the end. It is then stored and positioned in conjunction with the placement slot 7011 without the need for additional locking components. The rotary spring 404 drives the winding rod 402 to automatically wind up the pull rope 405. The pull rope 405 pulls the welding gun 106 wire harness through the connecting ring 407, avoiding tangling and bending, without the need for motor or manual operation. The pull rope 405 automatically extends and retracts as the welding torch 106 moves, and the wire harness management is linked in real time with the three-dimensional movement of the welding torch 106.

[0029] The working principle of the above embodiments is as follows: When using the device, the operator first places the metal pallet structure to be welded into the pallet frame 709. The support frame 10 on the lower side of the inner wall of the pallet frame 709 provides stable support for the pallet, and the support frame 10 does not obstruct the welding position. The operator fixes the fixing plate 9 to the periphery of the top surface of the pallet frame 709 with bolts to press and fix the pallet structure. After the equipment is started, the control cabinet 101 controls the horizontal guide rail 102 to drive the moving longitudinal plate 103 to move horizontally along the top surface of the support frame 2, the vertical guide rail 104 to drive the longitudinal guide rail 105 to move vertically, and the longitudinal guide rail 105 to drive the welding gun 106 to move longitudinally. The three work together to drive the welding gun 106 to move in three-dimensional space and automatically weld the weld seam on the front of the tray. The plasma arc welding machine 3 provides welding power to the welding gun 106 through the connecting wire harness. During the movement of the welding torch 106, the pulling component 4 works synchronously. The rotary spring 404 drives the winding rod 402 to maintain the winding trend. The winding rod 402 winds the pull rope 405. The lower end of the pull rope 405 is sleeved on the outer periphery of the connecting wire harness of the welding torch 106 through the connecting ring 407. When the welding torch 106 moves away from the support frame 2, the connecting wire harness pulls the pull rope 405 to overcome the elastic force of the rotary spring 404 and extend outward. When the welding torch 106 returns to its original position, the rotary spring 404 drives the winding rod 402 to wind the pull rope 405. The pull rope 405 pulls the connecting wire harness to retract, avoiding the connecting wire harness from tangling and repeated bending, and reducing the probability of damage to the connecting wire harness. After the front welding of the pallet is completed, the operator pulls out the fixed slot plate 6 and steps on the foot switch 803 at the same time. This drives the telescopic rod 801 to extend and the drive tooth plate 802 to move upward. The drive tooth plate 802 meshes with the power gear 707 at the end of the drive rod 706, driving the power gear 707 to rotate. The power gear 707 drives the drive rod 706 and the crank block 708 to rotate synchronously. When the crank block 708 rotates, it drives the pallet frame 709 to rotate horizontally around the vertical slider 711. During the flipping process, the vertical slider 711 slides in the vertical slot plate 702, and the horizontal slider 710 slides in the horizontal slot plate 701. The length of the vertical slider 711 is greater than the interval between the vertical slot plate 702 and the extension slot plate 703, and the length of the horizontal slider 710 is greater than the width of the vertical slot plate 702, to ensure stable sliding. The crank block 708 rotates in the interval channel between the vertical slot plate 702 and the extension slot plate 703. When the pallet frame 709 is flipped to the horizontal state, the crank block 708 is stored in the placement slot 7011 on the top surface of the horizontal slot plate 701, to ensure that the pallet frame 709 is placed horizontally and stably. After the pallet frame 709 is rotated 180°, the foot switch 803 is released, the drive telescopic rod 801 retracts, the drive gear plate 802 resets, the power gear 707 disengages from the drive gear plate 802, and the pallet frame 709 remains in a horizontal state after being rotated. The control cabinet 101 then controls the welding gun 106 to automatically weld the reverse side of the pallet. After welding is completed, the bolts of the fixing plate 9 are loosened, and the welded metal pallet is removed, completing one welding cycle. During the entire welding process, the pallet can be welded on both sides without being disassembled and reassembled. The next metal pallet processing requires rotating and operating in the same way as the above structure. The pulling force of the fixing plate 6 is used to ensure the rotation and welding of the metal pallet, avoiding the workload of traditional disassembly and fixing, and greatly increasing the processing efficiency of the metal pallet.

Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
