Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically an automatic turntable welding machine. Background Technology

[0002] Rotary table welding machines typically consist of a rotating worktable, a welding system, fixtures, and a control system. After the workpiece to be welded is fixed on the rotary table by the fixtures, the weld seam on the workpiece is aligned with the welding torch by rotating the workpiece. This eliminates the need to move the welding torch, significantly improving production efficiency.

[0003] A search revealed a Chinese patent (authorization announcement number CN218946748 U) disclosing a rotatable welding device after clamping. This patented technology includes a frame and solves the problem that in existing technologies, workpieces are typically clamped and secured using clamping plates. However, during welding, sometimes the top and bottom of the workpiece need to be welded, and the traditional fixing method makes it difficult to rotate the workpiece, thus significantly reducing welding efficiency. The rotatable welding device includes a frame with a top frame fixedly connected to the top, and welding equipment installed on the inner top of the top frame. Side plates are fixedly connected to both sides of the frame. The proposed method allows the workpiece clamped by the clamping plates to rotate under the drive of the support plate and support rod, thereby facilitating welding of the back side of the workpiece. Furthermore, the two clamping plates can clamp workpieces of different sizes.

[0004] In existing technologies, most turntable welding machines can only rotate the turntable horizontally, causing the workpiece to be welded to rotate horizontally as well. The weld seam on the side of the workpiece away from the welding robot is turned towards the welding robot. However, when the workpiece is large, the welding robot has difficulty welding the weld seam at the top of the workpiece. It is necessary to manually adjust the clamping method of the workpiece to align the weld seam at the top of the workpiece with the welding robot, which is inconvenient. In addition, the gears inside the turntable have a heavy load and wear out quickly. After the gears wear out, the accuracy of the turntable rotation will be affected, which will affect the accuracy of the welding robot when welding the weld seam. Therefore, this utility model provides an automatic turntable welding machine. Utility Model Content

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 7 As shown, this utility model provides a technical solution: an automatic turntable welding machine, including a base plate 1. A welding robot 11 is fixedly installed on one side of the top of the base plate 1. A fixed frame 12 is fixedly connected to the side of the top of the base plate 1 away from the welding robot 11. A rotating seat 13 is rotatably connected to the top of the fixed frame 12. Fixed plates 14 are symmetrically fixedly connected to the top of the rotating seat 13. Arc-shaped frames 15 are fixedly connected to the top of each of the two fixed plates 14. A rotating seat 2 16 is rotatably connected to the top of both arc-shaped frames 15. Limiting grooves 17 are opened on the inner walls of both arc-shaped frames 15. Arc-shaped plates 18 are symmetrically fixedly connected to both sides of the rotating seat 2 16. Both arc-shaped plates 18 are slidably connected to the limiting grooves 17. A fixed platform 19 is fixedly connected to the top of the rotating seat 2 16.

[0031] Through the above technical solution, the welding robot 11 can automatically weld the workpiece to be welded. This is existing technology and will not be elaborated on here. The arc frame 15 can rotate inside the arc frame 15, thereby driving the workpiece to be welded to rotate in the direction of the welding robot 11. In cases where the welding robot 11 has difficulty welding the top of the workpiece, it can drive the top of the workpiece to be welded to turn towards the welding robot 11, so that the welding robot 11 can contact the weld seam on the top of the workpiece and perform welding. This solves the problem that the welding robot 11 has difficulty contacting all the weld seams of a large workpiece to be welded, thereby improving the welding effect and efficiency. At the same time, with the cooperation of the limiting groove 17 and the arc plate 18, the rotating seat 16 can maintain a stable direction towards the welding robot 11, thereby improving the stability of the workpiece to be welded during the welding process.

[0032] Specifically, pin holes are provided at equal intervals on the top of the fixed platform 19.

[0033] The above technical solution allows for the installation of positioning pins for locating the workpiece to be welded through the pin hole, thereby fixing the workpiece and adapting to workpieces of different shapes. This is existing technology and will not be elaborated further here.

[0034] Specifically, a motor 2 is fixedly installed on the top of the base plate 1 near the fixed frame 12. A gear 21 is fixedly connected to the output shaft of the motor 2. A rotating seat 22 is rotatably connected to the bottom of the fixed frame 12. A gear 23 is fixedly connected to the outer surface of the rotating seat 22. Gear 21 and gear 23 mesh with each other. The top of the rotating seat 22 passes through the fixed frame 12 and is fixedly connected to the rotating seat 13. A motor 24 is fixedly installed on one side of the rotating seat 13. An arc-shaped groove 25 is opened at the bottom of the rotating seat 26. A worm gear 26 is fixedly connected inside the arc-shaped groove 25. A worm 27 is fixedly connected to the output shaft of the motor 24. The worm gear 27 meshes with the worm gear 26.

[0035] Through the above technical solution, when motor 2 starts, it drives gear 21 on its output end to rotate, which in turn drives gear 23 to rotate, which in turn drives rotating seat 22 to rotate. This causes rotating seat 22 to drive rotating seat 13 on its top to rotate, which in turn drives the arc frame 15, rotating seat 26 and fixed platform 19 to rotate horizontally. This, in turn, drives the workpiece to be welded to rotate horizontally, which facilitates the welding robot 11 to weld the weld seam on the side of the workpiece away from the welding robot 11 without the welding robot 11 needing to move, thus improving welding efficiency. At the same time, the rotation of the workpiece on the horizontal plane also ensures the welding accuracy after the workpiece rotates. When motor 24 starts, it drives worm 27 on its output end to rotate, which, through meshing with worm wheel 26, drives rotating seat 26 to rotate inside the arc frame 15, thereby achieving the effect of driving the workpiece to rotate vertically, thus solving the problem that the welding robot 11 has difficulty contacting the top weld seam of a large workpiece.

[0036] Specifically, both the arc groove 25 and the worm gear 26 are arc-shaped.

[0037] Through the above technical solution, the arcuate curvature of the arcuate groove 25 and the worm wheel 26 is the same as that of the rotating seat 16, so that when the worm 27 drives the worm wheel 26, the rotating seat 16, which rotates under the action of meshing connection, can rotate along the curvature of the arcuate frame 15.

[0038] Specifically, a lubrication box 3 is fixedly connected to the fixed frame 12, and a turntable 31 is fixedly connected to the output shaft of the motor 2. The turntable 31 is located directly above the gear 21. A notch 32 is provided on the edge of the turntable 31. Mounting plates 33 are symmetrically fixedly connected to the bottom of the lubrication box 3 on the side away from the fixed frame 12. An oil outlet 34 is fixedly connected to the bottom of the two mounting plates 33. A hole is provided on the bottom of the side of the lubrication box 3 near the oil outlet 34. An oil filling valve is provided on the top of the side of the lubrication box 3 away from the oil outlet 34. A baffle 35 is slidably connected between the two mounting plates 33. A fixed seat 36 is fixedly connected to the side of the lubrication box 3 near the mounting plates 33. A return spring 37 is fixedly connected between the fixed seat 36 and the baffle 35. A through hole 38 is provided on the side of the baffle 35 near the fixed seat 36. A circular groove 39 is provided on the side of the baffle 35 near the turntable 31. The circular groove 39 abuts against the edge of the turntable 31.

[0039] Through the above technical solution, when motor 2 drives gear 21 to rotate, causing the workpiece to be welded to rotate, the output shaft of motor 2 synchronously drives turntable 31 to rotate, causing notch 32 to continuously move closer to baffle 35 and then away. During this process, when notch 32 approaches and aligns with baffle 35, baffle 35, under the pushing action of return spring 37, slides between the two mounting pieces 33 toward turntable 31. When the center of notch 32 is directly opposite baffle 35, baffle 35 extends into notch 32, causing through hole 38 to move directly above oil outlet 34. At this time, the lubricating oil can pass through the holes and through holes 38 on the lubrication box 3, and then flow into the space between gear 1 21 and gear 23 through the oil outlet 34 under the action of gravity, so as to lubricate the meshing part of gear 1 21 and gear 23, thereby ensuring that gear 1 21 and gear 23 maintain the lubrication effect during long-term operation, reducing the wear of gear 1 21 and gear 23, extending the service life of gear 1 21 and gear 23, and at the same time avoiding the situation that the wear of gear 1 21 and gear 23 affects the welding accuracy, thus improving the welding accuracy.

[0040] Specifically, a control panel is provided on one side of the fixing plate 14, and the control panel is electrically connected to the welding robot 11, motor 1 2 and motor 2 24.

[0041] With the above technical solution, the welding robot 11, motor 1 2, and motor 2 24 can be controlled using the control panel.

[0042] In use, first add lubricating oil to the lubrication box 3 through the oil filling valve on the lubrication box 3. Then, place the workpiece to be welded on the top of the fixed platform 19 and install the positioning pin on the fixed platform 19 to fix the workpiece to be welded. Then, start the welding robot 11 and weld the weld seam on the side of the workpiece to be welded that is close to the welding robot 11. After welding is completed, motor 1 2 starts. Motor 1 2 drives gear 1 21 on the output end to rotate, which in turn drives gear 2 23 to rotate, which in turn drives rotating seat 3 22 to rotate. This causes rotating seat 3 22 to drive rotating seat 1 13 on its top to rotate, which in turn drives the arc frame 15, rotating seat 2 16 and fixed platform 19 to rotate horizontally, which in turn drives the workpiece to be welded to rotate horizontally, making it easier for the welding robot 11 to weld the weld seam on the side of the workpiece to be welded that is away from the welding robot 11. When motor 2 24 starts, motor 24 drives the worm gear 27 on its output end. The rotation causes the worm gear 27 to mesh with the worm wheel 26, driving the rotating seat 16 to rotate inside the arc frame 15, thereby achieving the effect of rotating the workpiece to be welded in the vertical direction. When the motor 2 drives the gear 21 to rotate, causing the workpiece to be welded to rotate, the output shaft of the motor 2 synchronously drives the turntable 31 to rotate, causing the notch 32 to continuously move closer to the baffle 35 and then away. During this process, when the notch 32 approaches the baffle 35 and is aligned, the baffle 35 slides towards the turntable 31 between the two mounting plates 33 under the pushing action of the return spring 37. When the center of the notch 32 is directly opposite the baffle 35, the baffle 35 extends into the notch 32, causing the through hole 38 to move directly above the oil outlet 34. At this time, the lubricating oil can pass through the holes and through hole 38 on the lubrication box 3, and then flow into the space between the gear 21 and the gear 23 under the action of gravity, lubricating the meshing point of the gear 21 and the gear 23.
