Description

Technical Field

[0001] This utility model relates to the field of automotive reinforcement plate assembly welding technology, and in particular to an automotive reinforcement plate assembly welding device. Background Technology

[0002] In modern automotive manufacturing, the steel plate assembly is a key structural component, and its quality and durability are directly related to the safety performance and service life of the entire vehicle. Steel plates are usually made of high-strength steel. In order to prevent the metal surface from rusting due to oxidation, extend its service life and maintain structural strength, rust prevention treatment is an essential process for steel plates.

[0003] After welding, existing automotive reinforcement plate assemblies typically require the use of a spray gun to apply anti-rust paint. While the spray gun can usually be moved and adjusted to spray different areas, it is often difficult to adaptively adjust the spraying angle and distance along the curve of the reinforcement plate for reinforcement plates with complex curved surfaces or specific arc shapes. This results in uneven paint thickness, which is quite inconvenient.

[0004] Therefore, it is necessary to design an automotive reinforcement plate assembly welding device that can adaptively adjust the spraying angle and distance along the arc of the reinforcement plate to ensure that the spraying frame always maintains the same distance from the reinforcement plate. Utility Model Content

[0005] To overcome the shortcomings of existing automotive reinforcement plate assembly welding devices, which often struggle to adaptively adjust the spraying angle and distance along the curve of reinforcement plates with complex curved surfaces or specific arc shapes after welding, resulting in uneven spraying thickness, this utility model provides an automotive reinforcement plate assembly welding device that can adaptively adjust the spraying angle and distance along the curve of the reinforcement plate, ensuring that the spraying frame always maintains the same distance from the reinforcement plate.

[0006] The technical implementation scheme of this utility model is as follows: a welding device for automotive reinforcing plate assembly, comprising a protective box, a motor, a bidirectional lead screw, a first sliding block, a first electric push rod, a clamping block, a first rodless cylinder, a robotic arm, a welding head, and a spraying assembly. The motor is connected to the lower right part of the protective box, and the bidirectional lead screw is rotatably connected to the lower middle part of the protective box. The bidirectional lead screw is connected to the output shaft of the motor. The left and right parts of the bidirectional lead screw are threadedly connected to the first sliding blocks, and the first sliding blocks are slidably connected to the protective box. Two first electric push rods are connected to the upper side of each first sliding block, and a clamping block is connected between the telescopic ends of two adjacent first electric push rods. The first rodless cylinder is connected to the inner side of the upper rear part of the protective box. A robotic arm is installed on the slider of the first rodless cylinder, and a welding head is connected to the robotic arm. The upper part of the protective box is provided with a spraying assembly that can adaptively adjust the spraying angle and distance along the arc of the reinforcing plate.

[0007] Furthermore, the protective box has a rotating door at the front, which is made of transparent material.

[0008] Furthermore, a smoke vent is provided on the upper left side of the protective box.

[0009] Furthermore, the clamping block has an L-shaped structure.

[0010] Furthermore, the spraying assembly includes a second rodless cylinder, a second sliding block, a second electric actuator, a support block, a slide rod, a spraying frame, a telescopic spring, a torsion spring, a dual-axis cylinder, rollers, and a feed pipe. The second rodless cylinder is connected to the upper part of the protective box. A second sliding block is connected to the slider of the second rodless cylinder, and the second sliding block is slidably connected to the protective box. A second electric actuator is connected to the lower side of the second sliding block, and a support block is connected to the telescopic end of the second electric actuator. Both the front and rear parts of the support block are slidably connected. The device is equipped with sliding frames, each with a sliding rod slidably connected to its far-away ends. Each sliding rod is connected to an adjacent sliding frame by a telescopic spring. Each sliding rod is rotatably connected to a spray frame on its close-to-far side, with a torsion spring connected to an adjacent sliding rod. A dual-axis cylinder is located below the support block, and each spray frame is connected to the adjacent telescopic end of the dual-axis cylinder. Rollers are rotatably connected to both the front and rear parts of the spray frame. A feed pipe is connected between the right sides of the spray frame, passing through the rear of the protective box.

[0011] Furthermore, the feed pipe is a flexible hose.

[0012] The present invention has the following advantages: 1. When the support block moves to the left, the left roller contacts the lower side of the reinforcing plate first. The upward pulling force of the telescopic spring will drive the spray frame to rotate, so that the right roller also contacts the lower side of the reinforcing plate. This achieves the effect of adaptively adjusting the spraying angle and distance along the arc of the reinforcing plate, ensuring that the spray frame always maintains the same distance from the reinforcing plate.

[0013] 2. This utility model starts the motor, drives the bidirectional lead screw to rotate, and causes the first sliding block to move under the action of the thread, so that the clamping blocks move closer to each other to limit and fix the reinforcing plate. This achieves the effect of clamping and limiting reinforcing plates of different lengths, which can easily adapt to different processing needs. Attached Figure Description

The motor 2 is connected to the lower right side of the protective box 1. The bidirectional lead screw 3 is rotatably connected to the lower middle part of the protective box 1 and is connected to the output shaft of the motor 2. The left side of the bidirectional lead screw 3... Both right sides are threadedly connected to the first sliding block 4, which is slidably connected to the protective box 1. The upper side of the first sliding block 4 is connected to the front and rear first electric push rods 5. The telescopic ends of the two adjacent first electric push rods 5 are connected to the clamping block 6, which has an L-shaped structure for easy clamping and fixing. The upper rear inner side of the protective box 1 is connected to the first rodless cylinder 7. The slider of the first rodless cylinder 7 is equipped with a mechanical arm 8, and the mechanical arm 8 is connected to the welding head 9. The upper part of the protective box 1 is equipped with a spraying assembly.

[0023] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the spraying assembly includes a second rodless cylinder 10, a second sliding block 11, a second electric push rod 12, a support block 13, a slide rod 15, a spraying frame 16, a telescopic spring 17, a torsion spring 18, a dual-axis cylinder 19, a roller 20, and a feed pipe 21. The second rodless cylinder 10 is connected to the upper part of the middle of the protective box 1. The second sliding block 11 is connected to the slider of the second rodless cylinder 10. The second sliding block 11 is slidably connected to the protective box 1. The second electric push rod 12 is connected to the lower side of the second sliding block 11. The support block 13 is connected to the telescopic end of the second electric push rod 12. The support block 13 is slidably connected to the front and rear parts of both sides of the front and rear parts of the front and rear parts. 4. Each sliding frame 14 has a sliding rod 15 slidably connected to one of its far ends. Each sliding rod 15 is connected to an adjacent sliding frame 14 by a telescopic spring 17. Each sliding rod 15 has a spray frame 16 rotatably connected to one of its close ends. Each spray frame 16 is connected to an adjacent sliding rod 15 by a torsion spring 18. The dual-axis cylinder 19 is located below the support block 13. Each spray frame 16 is connected to the telescopic end of the dual-axis cylinder 19. Rollers 20 are rotatably connected to both the front and rear parts of the spray frame 16. A feed pipe 21 is connected between the right sides of the spray frame 16. The feed pipe 21 is a flexible hose and passes through the rear of the protective box 1.

[0024] When using this device, firstly, place the protective box 1 in the welding area of ​​the automotive reinforcing plate assembly. During reinforcing plate production, stack the reinforcing plate assemblies between the clamping blocks 6. Then, start the motor 2 to drive the bidirectional lead screw 3 to rotate, causing the first sliding block 4 to move under the action of the thread, so that the clamping blocks 6 move closer together to limit and fix the reinforcing plate. This allows for clamping and limiting reinforcing plates of different lengths, facilitating adaptation to different processing requirements. Next, start the first electric push rod 5 to move the clamping blocks 6 upward, so that the reinforcing plate moves to the specified height. Then, start the first rodless cylinder 7 to move the robotic arm 8 left and right, so that the welding head 9 moves left and right. The angle of the welding head 9 is controlled by the robotic arm 8, and the welding head 9 moves left and right to weld the reinforcing plate. After welding is completed, start the second electric push rod 12 to move the support block 13 downward, so that the roller 20 is below the reinforcing plate. Then, start the dual-axis cylinder 19 to move the spraying frame 16, so that the spraying frames 16 move closer together, so that the sliding frame 14 moves on the support block 13. Then, the second electric push rod 12 moves the welding head 9 to weld the reinforcing plate. Push rod 12 controls the support block 13 to move upward, causing roller 20 to contact the lower side of the reinforcing plate. Then, the rotating door is closed by rotating the door. Rust-proof paint is then connected to the outside of the feed pipe 21. Next, the second rodless cylinder 10 is activated, driving the second sliding block 11 to move left and right, causing the support block 13 to move left and right. As the support block 13 moves left or right, the arc-shaped structure of the reinforcing plate causes the sliding rod 15 to gradually move downward, stretching the telescopic spring 17. When the support block 13 moves to the left, the left roller 20 will first contact the lower side of the reinforcing plate, and then... The upward tension of spring 17 causes the spray frame 16 to rotate, and the torsion spring 18 deforms, causing the right roller 20 to also contact the underside of the reinforcing plate. The anti-rust paint is sprayed onto the surface of the reinforcing plate through the spray frame 16, thereby adaptively adjusting the spraying angle and distance along the arc of the reinforcing plate to ensure that the spray frame 16 always maintains the same distance from the reinforcing plate. When the support block 13 moves to the middle of the reinforcing plate, the telescopic spring 17 and the torsion spring 18 return to their original positions, causing the slide rod 15 to move upward and reset, and the spray frame 16 to rotate and reset.
