[0001] The present invention relates to the technical field of conveyor lines, and more particularly to a hanging conveyor line for welding electric vehicle frames. Background Art

[0002] In the field of electric vehicle manufacturing, frame welding is a crucial process. Traditional frame welding conveyor methods have many problems. For example, during the conveying process, the frame is prone to vibration and impact, which can cause the frame to deform, thereby affecting the welding quality and the overall performance of the frame. At the same time, the flexibility of the traditional conveyor line structure is poor, making it difficult to adapt to the attitude and position changes of the frame during conveying, which may result in collisions between the frame and the conveying equipment, reducing production efficiency and increasing production costs. Moreover, the stability of the traditional conveyor line is not good. After long-term operation, the support structure of the conveyor line is prone to deformation or displacement, affecting the accuracy and safety of conveying. Therefore, there is an urgent need for a hanging conveyor line for welding electric vehicle frames that can effectively reduce vibration, improve flexibility and stability. Summary of the Invention

[0003] Aiming at the above technical deficiencies, the purpose of the present invention is to provide a hanging conveyor line for welding electric vehicle frames, which realizes the automatic and stable conveying of the frame through designs such as universal connection, buffer structure, guide wheels, and hinge drive, and improves the welding quality and production efficiency of the hanging conveyor line for welding electric vehicle frames.

[0025] The following uses specific embodiments to illustrate the present invention, but it does not limit the invention.

[0026] Embodiment 1 As Figures 1-7 shown, in this embodiment, an electric vehicle frame welding suspension conveyor line is provided, which includes a first support line 1 and a second support line 2.

[0027] The first support line 1 and the second support line 2 are arranged parallel to each other up and down. The first support line 1 and the second support line 2 are respectively provided with a first conveying channel and a second conveying channel inside. A suspension mechanism for suspending the vehicle frame is installed inside the two conveying channels. Inside the first conveying channel and the second conveying channel inside the first support line 1 and the second support line 2, the suspension mechanism can move along the channels.

[0028] Among them, the suspension mechanism includes a first carriage 3 slidably installed inside the first conveying channel and a second carriage 4 slidably installed inside the second conveying channel. The suspension mechanism further includes a suspension rod 5. The middle part of the suspension rod 5 is connected to the second carriage 4 through a universal structure. The upper end of the suspension rod 5 extends into the inside of the first carriage 3. A buffer structure for applying a buffer force to the suspension rod 5 is installed inside the first carriage 3. The suspension rod 5 is used to suspend the vehicle frame and is connected to the second carriage 4 through a universal structure. The buffer structure can apply a buffer force to the suspension rod 5 to reduce the vibration and impact during the suspension process. The suspension and conveying of the vehicle frame are realized. The buffer structure can protect the vehicle frame from being affected by excessive vibration during the conveying process, ensuring the integrity and welding quality of the vehicle frame. At the same time, the parallel support lines and the double-carriage structure up and down make the conveying more stable.

[0029] A universal ball is fixed in the middle of the suspension rod 5, and a concave spherical surface adapted to the universal ball is provided in the middle of the second carriage 4. The universal ball is installed inside the concave spherical surface. The universal ball in the middle of the suspension rod 5 is installed in the concave spherical surface in the middle of the second carriage 4. The universal ball can rotate flexibly inside the concave spherical surface, enabling the suspension rod 5 to swing at multiple angles centered on the universal ball, increasing the flexibility of the suspension rod 5, enabling the vehicle frame to adapt to different postures and position changes during the conveying process, and avoiding collisions or damages caused by rigid connections.

[0030] Embodiment 2 As Figures 1-4 shown, on the basis of Embodiment 1, this embodiment provides a multi-directional buffering effect for the suspension rod 5, specifically as follows: A frame 12 is slidably installed inside the first carriage 3. A tube sleeve 6 is provided inside the frame 12. A convex spherical surface is provided inside the tube sleeve 6. The middle part of the convex spherical surface is a curved surface bent inward. Both sides of the frame 12 are respectively connected inside the first carriage 3 through a first elastic body 7. When the suspension rod 5 is subjected to vibration or impact, it will push the frame 12 to slide inside the first carriage 3, and the first elastic body 7 deforms, thereby absorbing and buffering energy, further enhancing the buffering effect. Through the cooperation of the frame 12 and the first elastic body 7, the impact force transmitted from the suspension rod 5 to the first carriage 3 can be more effectively reduced, protecting the structural stability of the conveying line.

[0031] A slider 8 is slidably installed inside the frame 12. The tube sleeve 6 is fixed inside the slider 8. Both sides of the slider 8 are respectively connected inside the frame 12 through a second elastic body 13. When the suspension rod 5 is stressed, it will cause the slider 8 to slide inside the frame 12, and the second elastic body 13 deforms, absorbing and buffering energy again. Through the double buffering structure of the slider 8 and the second elastic body 13, the buffering performance is further improved, making the vehicle frame more stable during the conveying process and reducing the impact of vibration on the vehicle frame.

[0032] The upper end of the suspension rod 5 extends through the bushing 6 to the outside. There is a gap between the inner convex spherical surface of the bushing 6 and the suspension rod 5. When the suspension rod 5 swings or vibrates, it can move freely within the gap range, avoiding direct rigid collision with the bushing 6, ensuring the movement space of the suspension rod 5, reducing friction and collision, extending the service life of the suspension rod 5 and the bushing 6, and at the same time facilitating the buffer structure to play its role.

[0033] Both sides of the first support wire 1 and the second support wire 2 are connected by the fixing strip 15, fixing the two together to form a stable structure, enhancing the overall stability of the first support wire 1 and the second support wire 2, ensuring the structural strength of the conveyor line, and preventing the support wire from deforming or shifting due to external forces during the conveying process.

[0034] Embodiment Three As Figures 5-7 shown, on the basis of Embodiment One and Embodiment Two, this embodiment provides the installation methods of the first carriage 3 and the second carriage 4, which are specifically as follows: Both sides of the second carriage 4 are rotatably installed with the first guide wheels 10, and both sides of the top are rotatably installed with the second guide wheels 11. The first guide wheels 10 roll on the bottom surface of the first conveying channel, and the second guide wheels 11 roll on the side wall of the first conveying channel. The first guide wheels 10 on both sides of the second carriage 4 roll on the bottom surface of the first conveying channel, and the second guide wheels 11 on both sides of the top roll on the side wall of the first conveying channel. Through the rolling of the guide wheels, the second carriage 4 is guided to move smoothly along the first conveying channel, improving the stability and smoothness of the movement of the second carriage 4, reducing the friction with the conveying channel, lowering the energy consumption, and at the same time ensuring the accuracy of the frame conveying.

[0035] Both sides of the first carriage 3 are rotatably installed with the third guide wheels 14, and the third guide wheels 14 roll on the bottom surface of the second conveying channel. Through the rolling of the third guide wheels 14, the first carriage 3 is guided to move smoothly along the second conveying channel. The stability and smoothness of the movement of the first carriage 3 are enhanced, and in cooperation with the guide wheels of the second carriage 4, the entire suspension mechanism is more stable and reliable during the conveying process.

[0036] The first carriage 3 and the second carriage 4 are both fixed by the connecting rod 9. The first carriage 3 and the second carriage 4 are fixed by the connecting rod 9, making them a whole, and being able to maintain their relative positions unchanged during the movement, ensuring the integrity and stability of the suspension mechanism, avoiding misalignment or shaking of the first carriage 3 and the second carriage 4 during the movement, and ensuring the safety of the frame conveying.

[0037] Inside the second support line 2, there is a hinge that moves along the inside of the second transfer channel. The second carriage 4 is connected to the hinge. The hinge inside the second support line 2 moves along the second transfer channel, and the second carriage 4 is connected to the hinge. The movement of the hinge drives the second carriage 4 and the entire suspension mechanism to move within the transfer channel, providing the power for the movement of the suspension mechanism, enabling the vehicle frame to be continuously conveyed on the conveyor line, and realizing the automated welding and suspension conveyance of the vehicle frame.

[0038] Working principle: The working principle of this electric vehicle frame welding suspension conveyor line is based on the coordinated operation of each component. The hinge inside the second support line 2 moves along the second transfer channel. Since the second carriage 4 is connected to the hinge, the movement of the hinge drives the second carriage 4 to slide within the second transfer channel. The first carriage 3 and the second carriage 4 are fixed as a whole through the connecting rod 9, so the first carriage 3 will also move synchronously with the second carriage 4 within the first transfer channel.

[0039] The vehicle frame is suspended through the suspension rod 5. The universal ball in the middle of the suspension rod 5 is installed in the concave spherical surface in the middle of the second carriage 4, enabling the suspension rod 5 to swing at multiple angles, so that the vehicle frame can adapt to different postures and position changes during the conveying process. When the suspension rod 5 is subjected to vibration or impact, the upper end of the suspension rod 5 will generate corresponding movements within the first carriage 3. The upper end of the suspension rod 5 passes through the sleeve 6, and the sleeve 6 is installed on the slider 8 inside the frame body 12. At this time, the suspension rod 5 will push the slider 8 to slide within the frame body 12, and the second elastic bodies 13 on both sides of the slider 8 will deform, absorbing and buffering part of the energy. At the same time, the movement of the slider 8 will drive the frame body 12 to slide within the first carriage 3, and the first elastic bodies 7 on both sides of the frame body 12 will also deform, further absorbing and buffering the energy, and reducing the impact force transmitted from the suspension rod 5 to the first carriage 3.

[0040] During the movement, the first guide wheels 10 on both sides of the second carriage 4 roll on the bottom surface of the first transfer channel, and the second guide wheels 11 on both sides of the top roll on the side walls of the first transfer channel; the third guide wheels 14 on both sides of the first carriage 3 roll on the bottom surface of the second transfer channel. The rolling of these guide wheels guides the carriage to move smoothly along the transfer channel, reducing the friction with the transfer channel, and ensuring the accuracy and stability of the vehicle frame conveyance.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or equivalently replaced. Any modification or partial replacement without departing from the spirit and scope of the present invention shall be covered by the scope of the claims of the present invention.
