[0001] The invention relates to the technical field of welding platforms, in particular to an automatic welding platform for a steel pallet. Background Art

[0002] In modern industrial production, steel pallets are an important means of logistics and transportation. Their quality and production efficiency directly affect the operating efficiency and cost of the entire supply chain. In order to meet the growing market demand for steel pallets, automatic welding technology is widely used in the manufacturing process of steel pallets to improve production efficiency and product quality. However, the existing steel pallet automatic welding platform still has some technical defects, which limits its further improvement in performance.

[0003] The steel pallet automatic welding platform in the prior art usually adopts a simple mechanical clamping device to fix the steel pallet workpiece. These clamping devices often lack sufficient flexibility and adaptability, and it is difficult to meet the clamping requirements of steel pallet workpieces of different shapes and sizes. During the clamping process, due to the lack of an effective buffer mechanism, the clamping force is often too large, which easily causes damage to the workpiece, and increases the wear of the control components, reducing the reliability and service life of the equipment;

[0004] In addition, the steel pallet automatic welding platform in the prior art also has shortcomings in terms of workpiece stability. During the welding process, the workpiece is subject to high temperature and mechanical stress, and is prone to shaking or falling off, which not only affects the welding quality but may also lead to safety accidents. In order to solve this problem, some platforms use additional fixing devices to enhance the stability of the workpiece, but these devices are often complex in structure and cumbersome to operate, which increases production costs and labor intensity.

The rotating connection design between the first V-frame and the clamping plate enables the component to flexibly adapt to steel pallet workpieces of different shapes and sizes, providing a flexible clamping solution. By activating the third cylinder, the trapezoidal rod, rectangular frame, positioning plate and pressure rod work together to achieve a downward thrust on the steel pallet workpiece from the top, which works together with the clamping force on the side to significantly enhance the stability of the workpiece and prevent it from shaking or falling off during welding. Through the interaction of components such as the sliding block, tilting block, guide rod and tilting groove, as well as the cooperation of the second damping spring and the push block, the position of the pressure rod can be dynamically adjusted according to actual needs to achieve precise positioning and meet the fixation requirements of steel pallet workpieces of different sizes and shapes.

[0016] The cam is driven by a servo motor to rotate, which in turn pushes the knocking rod to knock the positioning plate and the pressure rod, transmitting the vibration to the steel pallet workpiece during the welding process, thereby promptly eliminating the welding stress generated inside the workpiece, avoiding problems such as workpiece deformation and cracking, and improving the stability and durability of the workpiece. At the same time, it also helps to make the microstructure inside the weld metal more uniform, reduce defects in the weld, and improve the strength and toughness of the welded joint.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Embodiment 1: Combination Figure 1-Figure 8 As shown, the present invention provides a technical solution: an automatic welding platform for a steel pallet, comprising a base 1, a support plate 3 is fixedly installed around the top of the base 1, a welding assembly 2 is arranged on the outer side of the support plate 3, and a control assembly 4 for controlling the steel pallet workpiece is arranged on the support plate 3;

[0028] The control assembly 4 includes a fixed plate 41 fixedly mounted on both sides of the support plate 3, the inner ends of the two fixed plates 41 are rotatably connected to the first V-shaped frames 42, the inner ends of the two first V-shaped frames 42 are rotatably connected to the clamping plates 43, a second cylinder 44 is fixedly mounted on the fixed plate 41, and a control rod 45 is arranged at the output end of the second cylinder 44, a moving groove is arranged at the inner end of the first V-shaped frame 42, and the end of the control rod 45 is slidably mounted in the moving groove. When the steel pallet workpiece needs to be fixed, the control rod 45 is pushed to move inward by turning on the second cylinder 44, so that the control rod 45 slides in the moving groove, thereby pushing the first V-shaped frame 42 to move. The inner side rotates, so that the first V-shaped frame 42 drives the clamping plate 43 to rotate inwardly, so that the two first V-shaped frames 42 clamp the steel pallet workpiece, and are firmly installed on both sides of the support plate 3 through the fixing plate 41, thereby ensuring the structural strength and stability of the entire control component 4. The rotating connection design of the first V-shaped frame 42 and the clamping plate 43 enables the component to adapt to steel pallet workpieces of different shapes and sizes, providing a flexible clamping solution and enhancing the versatility and adaptability of the equipment; the design of the clamping plate 43 usually takes into account the friendly contact with the steel pallet workpiece, and adopts wear-resistant and anti-slip materials to avoid damage to the workpiece surface during the clamping process;

[0029] A telescopic rod 47 is rotatably connected to the fixed plate 41, and a connecting rod 46 is provided at the other end of the telescopic rod 47. Both ends of the connecting rod 46 are connected to the first V-shaped frame 42. A first damping spring 48 is provided on the telescopic rod 47. When the first V-shaped frame 42 rotates inward, the first V-shaped frame 42 drives the connecting rod 46 to rotate inward, and the connecting rod 46 controls the telescopic rod 47 to contract and compress the first damping spring 48. When the first V-shaped frame 42 rotates outward, the first V-shaped frame 42 is reset under the elastic force of the first damping spring 48. When the first V-shaped frame 42 rotates inward, the first V-shaped frame 42 is reset under the elastic force of the first damping spring 48. When the steel pallet workpiece is clamped, the connecting rod 46 rotates inwardly and drives the telescopic rod 47 to contract, while compressing the first damping spring 48. In this process, the first damping spring 48 plays a buffering role, which can absorb the impact force generated during the clamping process to avoid damage to the steel pallet workpiece. At the same time, it also reduces the wear of the control component 4 itself and enhances the stability and safety of the clamping. The elastic force of the first damping spring 48 enables the first V-shaped frame 42 to automatically reset when it rotates outward, which not only improves the flexibility of the clamping operation, but also ensures the stability of the clamping accuracy.

[0030] Guide rods 419 are slidably connected to both sides of the fixing plate 41, and a rectangular frame 411 is fixedly connected to the bottom end of the guide rod 419, and a trapezoidal rod 410 is fixedly connected to the inner end of the rectangular frame 411. A third cylinder 422 is fixedly installed on the top of the fixing plate 41, and the output end of the third cylinder 422 is fixedly connected to the trapezoidal rod 410. A positioning plate 412 is slidably connected to the bottom of the rectangular frame 411, and inclined grooves 416 are provided on both sides of the surface of the positioning plate 412. A pressing rod 413 is fixedly connected to the bottom of the positioning plate 412. By turning on the third cylinder 422, the trapezoidal rod 410 is driven to move downward, so that the trapezoidal rod 410 pushes the rectangular frame 411, the positioning plate 412, and the pressing rod 413 to move downward, so that the pressing rod 413 moves downward. The steel pallet workpiece is moved to the top of the steel pallet workpiece, and a downward thrust is applied to the steel pallet workpiece, so that the steel pallet workpiece can be fixed on the support plate 3. The trapezoidal rod 410 is driven to move vertically downward in the rectangular frame 411 by the third cylinder 422, thereby driving the positioning plate 412 and the pressure rod 413 to descend synchronously, so as to realize a downward thrust on the steel pallet workpiece from the top. This design not only increases the fixing method, but also significantly enhances the stability of the steel pallet workpiece through multi-point contact, such as the side clamping of the clamping plate 43 and the top push of the pressure rod 413, to prevent shaking or falling off during welding. The design of the guide rod 419 and the rectangular frame 411 not only ensures the smooth movement of the trapezoidal rod 410 in the vertical direction;

[0031] A slide groove 49 is provided at the inner end of the rectangular frame 411, and a slide block 414 is slidably connected to the slide groove 49 through a slide rod 423. A guide rod 415 slidably installed in the inclined groove 416 is fixedly connected to the bottom of the slide block 414. A second damping spring 421 is provided at the inner end of the slide groove 49, and a push block 420 is fixedly connected to one end of the second damping spring 421, and the push block 420 is located at the inner end of the slide rod 423; vertical rods are fixedly connected to both sides of the fixed plate 41 417, a row of inclined blocks 418 are fixedly connected to the inner end of the vertical rod 417 in the vertical direction, and the sliding block 414 is slidably adapted to the inclined block 418. When the trapezoidal rod 410 and the rectangular frame 411 move downward, the sliding block 414 can be driven to move downward synchronously. When the sliding block 414 moves downward, under the action of the row of inclined blocks 418, the sliding block 414 is located on the rectangular frame 411 and slides inwardly and compresses the second damping spring 421, and the sliding block 414 is When the row block 414 moves inward, the sliding block 414 drives the guide rod 415 to move inward synchronously, so that the guide rod 415 is located in the inclined groove 416 and slides, and then the guide rod 415 drives the positioning plate 412 and the pressure rod 413 to move outward. When the sliding block 414 moves and slides over the inclined block 418, the sliding block 414 pushes the pushing block 420 to move outward under the elastic force of the second damping spring 421, so that the pushing block 420 cooperates with the sliding rod 423 to push the sliding block 414 to move outward, and then the sliding block 414 is located in the inclined groove 416 through the guide rod 415 and slides, so that the guide rod 415 drives the positioning plate 412 and the pressure rod 413 to move inward, so that the position of the pressure rod 413 can be adjusted. This design allows the position of the pressure rod 413 to be dynamically adjusted according to actual needs, to achieve precise positioning, and to meet the fixing requirements of steel pallet workpieces of different sizes and shapes;

[0032] A servo motor 424 is fixedly installed at one end of the rectangular frame 411, and a rotating rod 425 rotatably installed on the rectangular frame 411 is fixedly connected to the output end of the servo motor 424. A cam 426 is fixedly connected to the rotating rod 425. A positioning rod 427 is rotatably connected to the rectangular frame 411. A second V-shaped frame 428 is fixedly connected to the positioning rod 427, and the outer wall of the cam 426 slides in contact with one end of the second V-shaped frame 428. A knocking rod 429 is fixedly connected to the other end of the second V-shaped frame 428. By turning on the servo motor 424, the rotating rod 425 is driven to rotate synchronously, and the rotating rod 425 drives the cam 426 to rotate synchronously. When the cam 426 rotates, it pushes the second V-shaped frame 428 to rotate, so that the second V-shaped frame 428 drives The knocking rod 429 rotates upward, and as the cam 426 rotates, the knocking rod 429 moves downward under the action of its own gravity, so that the knocking rod 429 knocks the positioning plate 412 and the pressure rod 413, thereby transmitting the vibration to the steel pallet workpiece during the welding process. By knocking the steel pallet workpiece, the welding stress generated inside the steel pallet workpiece can be eliminated in time, thereby avoiding problems such as deformation and cracking of the workpiece. Through the knocking and vibration treatment, these welding stresses can be effectively released and relieved, and the stability and durability of the workpiece can be improved. The knocking and vibration can help to make the microstructure inside the weld metal more uniform, reduce defects such as pores and slag inclusions in the weld, thereby improving the strength and toughness of the weld joint.

[0033] In the embodiment of the present invention, when the steel pallet workpiece is fixed, the second cylinder 44 is usually started. This action will prompt the control rod 45 to move inward, so that it can slide smoothly in the moving groove. As the control rod 45 moves inward, the first V-frame 42 will rotate inward, thereby driving the inner side of the clamping plate 43 to rotate. This continuous action enables the two first V-frames 42 to tightly clamp the steel pallet workpiece, ensuring the stable fixation of the workpiece. In order to enhance the structural strength and stability of the entire control component 4, the fixing plate 41 is firmly mounted on both sides of the support plate 3. In addition, the rotating connection design between the first V-frame 42 and the clamping plate 43 enables the component to flexibly adapt to steel pallet workpieces of different shapes and sizes, providing a flexible clamping solution, thereby enhancing the versatility and adaptability of the equipment. In the design of the clamping plate 43, we usually take into account the contact with the steel pallet workpiece and use wear-resistant and non-slip materials to avoid damage to the workpiece surface during the clamping process.

[0034] When the first V-shaped frame 42 rotates inwardly, it drives the connecting rod 46 to rotate inwardly as well. The rotation of the connecting rod 46 controls the telescopic rod 47 to retract and compress the first damping spring 48. On the contrary, when the first V-shaped frame 42 rotates outwardly, it resets under the elastic force of the first damping spring 48. In the process of the first V-shaped frame 42 rotating inwardly to clamp the steel pallet workpiece, the connecting rod 46 also rotates inwardly therewith and drives the telescopic rod 47 to retract and compresses the first damping spring 48 at the same time. In this process, the first damping spring 48 plays a buffering role, which can absorb the impact force generated during the clamping process to avoid damage to the steel pallet workpiece. At the same time, this buffering effect also reduces the wear of the control component 4 itself, thereby enhancing the stability and safety of the clamping. The elastic force of the first damping spring 48 also ensures that the first V-shaped frame 42 can automatically reset when it rotates outwardly, which not only improves the flexibility of the clamping operation, but also ensures the stability of the clamping accuracy.

[0035] By activating the third cylinder 422, we can make the trapezoidal rod 410 move downward, thereby pushing the rectangular frame 411, the positioning plate 412, and the pressure rod 413 to move downward together. In this way, the pressure rod 413 will move to the top of the steel pallet workpiece and exert a downward thrust to ensure that the steel pallet workpiece is fixed on the support plate 3. The third cylinder 422 drives the trapezoidal rod 410 to move vertically downward in the rectangular frame 411, thereby driving the positioning plate 412 and the pressure rod 413 to descend synchronously, thereby achieving a downward thrust on the steel pallet workpiece from the top. This design not only increases the fixing method, but also significantly enhances the stability of the steel pallet workpiece through multi-point contact, such as the side clamping of the clamping plate 43 and the top push of the pressure rod 413, to prevent shaking or falling off during welding. The design of the guide rod 419 and the rectangular frame 411 ensures the smooth movement of the trapezoidal rod 410 in the vertical direction;

[0036] When the trapezoidal rod 410 and the rectangular frame 411 move downward, they can drive the sliding block 414 to move downward synchronously. During the downward movement of the sliding block 414, under the action of a row of inclined blocks 418, the sliding block 414 will slide inward and compress the second damping spring 421. When the sliding block 414 moves inward, it will drive the guide rod 415 to move inward synchronously, so that the guide rod 415 slides in the inclined groove 416. The sliding of the guide rod 415 further drives the positioning plate 412 and the pressure rod 413 to move outward. When the sliding block 414 moves from the inclined block 418 When sliding upward, the elastic force of the second damping spring 421 pushes the push block 420 to move outward, so that the push block 420 cooperates with the slide bar 423 to push the slide block 414 to move outward, and the slide block 414 slides in the inclined groove 416 through the guide rod 415, so that the guide rod 415 drives the positioning plate 412 and the pressure rod 413 to move inward, so that the position of the pressure rod 413 can be adjusted. This design allows the position of the pressure rod 413 to be dynamically adjusted according to actual needs, to achieve precise positioning, and to meet the fixing requirements of steel pallet workpieces of different sizes and shapes;

[0037] By starting the servo motor 424, the rotating rod 425 will rotate synchronously, thereby driving the cam 426 to rotate together. During the rotation process, the cam 426 will push the second V-frame 428 to rotate, so that the second V-frame 428 drives the knocking rod 429 to rotate upward. As the cam 426 continues to rotate, the knocking rod 429 moves downward under the action of its own gravity, and knocks the positioning plate 412 and the pressure rod 413, thereby transmitting the vibration to the steel pallet workpiece during the welding process. By knocking the steel pallet workpiece, the welding stress generated inside the workpiece can be eliminated in time to avoid problems such as deformation and cracking of the workpiece. Through the knocking and vibration treatment, these welding stresses can be effectively released and relieved, thereby improving the stability and durability of the workpiece. In addition, the knocking and vibration help to make the microstructure inside the weld metal more uniform, reduce defects such as pores and slag inclusions in the weld, thereby improving the strength and toughness of the welded joint.
