Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and specifically discloses an intelligent welding device. Background Technology

[0002] In modern industrial production, welding is a key processing technology widely used in machinery manufacturing, steel structure, and automobile manufacturing. With the development of automation technology, higher demands are placed on the intelligence, precision, and adaptability of welding equipment. In actual production, it is often necessary to perform double-sided welding on two rectangular plates.

[0003] In existing technologies, the butt welding and positioning of plates relies on manual operation. This requires manually adjusting the relative positions of the two plates and controlling the butt gap, followed by rigid clamping with fixtures, and finally, the welding torch moves along a predetermined trajectory to complete the welding. However, this manual adjustment method has the following significant drawbacks:

[0004] 1. It is difficult to accurately control the butt joint precision of the plates, which can easily lead to misalignment of the plates during the welding process and make it impossible to ensure uniform butt joint gap, directly affecting the weld penetration quality and forming precision.

[0005] 2. Traditional clamps are mostly rigid structures, making it difficult to control the clamping force according to the material (such as easily deformable aluminum alloys) and thickness of the sheet metal. This can easily cause damage to the surface of the sheet metal or loose clamping, and may even cause displacement during the welding process, seriously affecting the welding stability.

[0006] 3. When performing double-sided welding, the plates need to be manually flipped and re-clamped, which is cumbersome and time-consuming, making it difficult to meet the needs of automated production lines for efficient and continuous operation.

[0007] Therefore, an intelligent welding device is needed to solve the above problems. Utility Model Content

[0014] As a preferred embodiment of the intelligent welding equipment of this utility model, the driving mechanism includes a driving frame fixedly connected to the left end of the left vertical plate, a worm gear rotatably connected inside the driving frame, a second servo motor whose output end is fixedly connected to the worm gear is installed on the outer wall of the driving frame, a worm wheel is meshed with the outer wall of the worm gear, and a transmission shaft is fixedly connected between the worm wheel and the steering shaft located on the left side.

[0015] As a preferred embodiment of the intelligent welding equipment of this utility model, the welding mechanism includes a third electric push rod installed on the upper end of a rectangular mounting frame. The output end of the third electric push rod passes through the upper end of the rectangular mounting frame and is fixedly connected to a U-shaped guide plate.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0030] Please see Figure 1-4 A smart welding device includes a rectangular mounting frame 1. The rectangular mounting frame 1 has two positioning and clamping mechanisms inside. The two positioning and clamping mechanisms include two positioning plates 14. A U-shaped positioning frame 15 is fixedly connected to one side of each of the two positioning plates 14. A first electric push rod 18 is installed at the upper end of each of the two U-shaped positioning frames 15. The output end of each of the two first electric push rods 18 passes through the upper end of the two U-shaped positioning frames 15 and is fixedly connected to a first pressure sensor 20. A clamping plate 21 is fixedly connected to the lower end of each of the two first pressure sensors 20. A first controller 19 is installed at the upper end of each of the two U-shaped positioning frames 15.

[0031] The inner wall of the rectangular mounting frame 1 is rotatably connected to the left and right sides of the ball screw 2. The outer wall of the rectangular mounting frame 1 is equipped with a first servo motor 6 whose output end is fixedly connected to the ball screw 2 located on the left side. The outer walls of the two ball screws 2 are threaded with ball screw nuts 4. The outer walls of the two ball screw nuts 4 are fixedly connected with movable seats 3.

[0032] Vertical plates 7 are fixedly connected to the upper ends of the two movable seats 3. Bearings 8 are fixedly connected through the outer walls of the two vertical plates 7. Steering shafts 9, which are fixedly connected to the two positioning plates 14 respectively, are fixedly connected inside the two bearings 8. A shaft 22 is fixedly connected to the right end of the right bearing 8. A rectangular block 23 is fixedly connected to the right end of the shaft 22. A limit mechanism is provided on the lower side of the rectangular block 23. A drive mechanism is provided on the left side of the left steering shaft 9.

[0033] A welding mechanism is provided between the two vertical plates 7.

[0034] In this embodiment: two rectangular plates to be welded are placed in two U-shaped positioning frames 15 respectively. It is necessary to ensure that the plates are in contact with the bottom end and the back side of the inner wall of the U-shaped positioning frame 15, and that the plates are in contact with the positioning plate 14, so as to position the plates and prevent the two plates from being misaligned.

[0035] Then the first electric push rod 18 is activated, pushing the clamping plate 21 downward until it contacts the upper surface of the plate. The first pressure sensor 20 monitors the clamping force in real time. When the pressure value reaches the preset value that matches the material and thickness of the plate, the first controller 19 automatically stops the first electric push rod 18. In this way, the surface of the plate is not damaged or not clamped properly.

[0036] Subsequently, the left ball screw 2 is driven to rotate by the first servo motor 6, which in turn drives the right ball screw 2 to rotate synchronously. This causes the two moving seats 3 to move towards each other, and simultaneously drives the two vertical plates 7, the two steering shafts 9, and the two fixed plates to move towards each other to the target position according to the preset program. The transmission of the first servo motor 6 and the ball screw 2 in conjunction with the ball screw nut 4 has the characteristics of high precision, so that the distance between the two plates is equal to the preset gap. At this time, the welding torch 17 is located directly above the plate joint, thereby achieving precise control of the plate joint gap and preventing plate misalignment, thus improving the welding quality.

[0037] The welding mechanism can then complete the front welding of the two plates. After the front welding is completed, the locking mechanism releases the rectangular block 23, and the drive mechanism drives the left steering shaft 9 to rotate. The left steering shaft 9 drives the positioning plate 14, the U-shaped positioning frame 15 and the clamped plate to rotate 180 degrees synchronously. The right steering shaft 9 rotates synchronously to ensure a smooth flipping process. After the plate is flipped into place, the locking mechanism locks the rectangular block 23. Then, the back of the plate is welded according to the same principle as above. In this way, the plate can be automatically flipped during double-sided welding, thereby improving work efficiency.

[0038] Through real-time data interaction between the first pressure sensor 20 and the first controller 19, high-precision transmission between the ball screw 2 and the servo motor, and coordinated linkage between the drive mechanism and the limit mechanism, the equipment can autonomously complete plate positioning, adaptive adjustment of clamping force, precise control of gap, and automatic switching of double-sided welding. The entire process requires no manual intervention, improving the intelligent control of the welding process and significantly enhancing the stability of welding quality and production efficiency under complex working conditions.

[0039] As a technical optimization of this utility model, the limiting mechanism includes a support plate 24 fixedly connected to the right end of the right vertical plate 7. A second electric push rod 25 is installed at the lower end of the support plate 24. The output end of the second electric push rod 25 passes through the support plate 24 and is fixedly connected to a second pressure sensor 26. A limiting plate 27 that fits against the lower end of the rectangular block 23 is fixedly connected to the upper end of the second pressure sensor 26. A second controller 28 is installed at the upper end of the support plate 24.

[0040] In this embodiment: when the locking state of the rectangular block 23 is released, the second electric push rod 25 retracts, causing the limiting plate 27 to descend, thereby releasing the locking of the rectangular block 23;

[0041] When it is necessary to lock the rectangular block 23, the second electric push rod 25 extends, the limit plate 27 re-attaches the rectangular block 23, and the rectangular block 23 is locked. The locking pressure on the rectangular block 23 is monitored by the second pressure sensor 26. When the predetermined pressure value is reached, the second electric push rod 25 is controlled by the second controller 28 to stop extending.

[0042] As a technical optimization of this utility model, the drive mechanism includes a drive frame 10 fixedly connected to the left end of the left vertical plate 7. A worm gear 11 is rotatably connected inside the drive frame 10. A second servo motor 13 with its output end fixedly connected to the worm gear 11 is installed on the outer wall of the drive frame 10. A worm wheel 12 is meshed with the outer wall of the worm gear 11. A transmission shaft is fixedly connected between the worm wheel 12 and the steering shaft 9 located on the left.

[0043] In this embodiment: the second servo motor 13 drives the worm gear 11 to rotate, which in turn drives the left steering shaft 9 to rotate through the worm wheel 12 and the transmission shaft. Since the worm wheel 12 and worm gear 11 transmission has a self-locking characteristic, the stability of the steering shaft 9 of the second servo motor 13 in the non-starting state is improved, and the angle of the fixed plate material is prevented from changing.

[0044] As a technical optimization of this utility model, the welding mechanism includes a third electric push rod 29 installed on the upper end of the rectangular mounting frame 1. The output end of the third electric push rod 29 passes through the upper end of the rectangular mounting frame 1 and is fixedly connected to a U-shaped guide plate 30. A lead screw 31 is rotatably connected inside the U-shaped guide plate 30. A third servo motor 16 with its output end fixedly connected to the lead screw 31 is installed on the outer wall of the U-shaped guide plate 30. A mounting seat 32 is threadedly connected to the outer wall of the lead screw 31 and is slidably connected to the U-shaped guide plate 30 via a slide rail. A welding torch 17 is installed at the lower end of the mounting seat 32. Two slide rods that pass through the rectangular mounting frame 1 and are slidably connected to the upper end of the U-shaped guide plate 30 are fixedly connected to the upper end of the U-shaped guide plate 30.

[0045] In this embodiment: when welding is required, the third electric actuator 29 pushes the U-shaped guide plate 30, the mounting base 32, and the welding torch 17 downwards, adjusting the height of the welding torch 17 to the optimal welding position. Then, the third servo motor 16 drives the lead screw 31 to rotate, causing the mounting base 32 to move laterally along the slide rail of the U-shaped guide plate 30, aligning the welding torch 17 with the weld start point. Subsequently, the third servo motor 16 drives the welding torch 17 to move at a constant speed along the weld trajectory, thereby completing the welding. By setting two sliding rods, the stability of the U-shaped guide plate 30 moving up and down is improved. It should be noted that the specific welding principle and structure of the welding torch 17 are existing technologies. In this device, the main functions are to adjust the position and move the trajectory of the welding torch 17.

[0046] As a technical optimization of this utility model, a groove is provided at the lower end of the inner wall of the rectangular mounting frame 1, and two sliders are slidably connected inside the groove. The two sliders are respectively fixedly connected to two movable seats 3.

[0047] In this embodiment, the stability of the movement of the two moving seats 3 is improved by setting a slide groove and two sliders.

[0048] As a technical optimization of this utility model, the threads of the two ball screws 2 are opposite.

[0049] In this embodiment: Since the threads of the two ball screws 2 are opposite, the two moving seats 3 can be driven to move synchronously relative to each other or in opposite directions.

[0050] As a technical optimization of this utility model, a synchronous shaft 5 is fixedly connected between the two ball screws 2.

[0051] In this embodiment: by setting a synchronous shaft 5, it is convenient to connect the two ball screws 2, so that the two ball screws 2 rotate synchronously.

[0052] The working principle and usage process of this utility model are as follows: Two rectangular plates to be welded are placed in two U-shaped positioning frames 15 respectively. It is necessary to ensure that the plates are in contact with the bottom end and the back side of the inner wall of the U-shaped positioning frame 15, and that the plates are in contact with the positioning plate 14, thereby positioning the plates and preventing the two plates from being misaligned.

[0053] Then the first electric push rod 18 is activated, pushing the clamping plate 21 downward until it contacts the upper surface of the plate. The first pressure sensor 20 monitors the clamping force in real time. When the pressure value reaches the preset value that matches the material and thickness of the plate, the first controller 19 automatically stops the first electric push rod 18. In this way, the surface of the plate is not damaged or not clamped properly.

[0054] Subsequently, the left ball screw 2 is driven to rotate by the first servo motor 6, and the right ball screw 2 is driven to rotate synchronously by the synchronous shaft 5. Since the threads of the two ball screws 2 are opposite, the two moving seats 3 are driven to move towards each other along the slide groove at the lower end of the inner wall of the rectangular mounting frame 1. At the same time, the two vertical plates 7, the two steering shafts 9, and the two fixed plates are driven to move towards each other to the target position according to the preset program. The transmission of the first servo motor 6 and the ball screw 2 in conjunction with the ball screw nut 4 has the characteristics of high precision, so that the distance between the two plates is equal to the preset gap. At this time, the welding gun 17 is located directly above the plate joint, so as to achieve precise control of the plate joint gap and prevent the plates from misaligning, thereby improving the welding quality.

[0055] When welding is required, the third electric actuator 29 pushes the U-shaped guide plate 30, the mounting base 32 and the welding torch 17 downward to adjust the height of the welding torch 17 to the optimal welding position. Then, the third servo motor 16 drives the lead screw 31 to rotate, which drives the mounting base 32 to move laterally along the slide rail of the U-shaped guide plate 30, so that the welding torch 17 is aligned with the starting point of the weld. Then, the third servo motor 16 drives the welding torch 17 to move at a constant speed along the weld track to complete the welding of the front side of the plate.

[0056] After welding is completed, the welding torch 17 is moved upward to a safe position, and the second electric push rod 25 is retracted, causing the limiting plate 27 to descend and releasing the lock on the rectangular block 23. The second servo motor 13 drives the worm gear 11 to rotate, which drives the left steering shaft 9 to rotate through the worm wheel 12 and the transmission shaft. The left steering shaft 9 drives the positioning plate 14, the U-shaped positioning frame 15 and the clamped plate to rotate 180 degrees synchronously. The right steering shaft 9 rotates synchronously to ensure a smooth flipping process. After the plate is flipped into place, the second electric push rod 25 extends, and the limiting plate 27 re-attaches to the rectangular block 23 to lock the rectangular block 23. The locking pressure on the rectangular block 23 is monitored by the second pressure sensor 26. When the predetermined pressure value is reached, the second controller 28 controls the second electric push rod 25 to stop extending. Then, welding is performed on the back of the plate according to the same principle as above. In this way, the plate can be automatically flipped during double-sided welding, thereby improving work efficiency.

[0057] Through real-time data interaction between the first pressure sensor 20 and the first controller 19, high-precision transmission between the ball screw 2 and the servo motor, and coordinated linkage between the drive mechanism and the limit mechanism, the equipment can autonomously complete plate positioning, adaptive adjustment of clamping force, precise control of gap, and automatic switching of double-sided welding. The entire process requires no manual intervention, improving the intelligent control of the welding process and significantly enhancing the stability of welding quality and production efficiency under complex working conditions.
