Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more specifically to a conveyor line for welding and suspending electric vehicle frames. Background Technology

[0002] In the field of electric vehicle manufacturing, frame welding is a crucial step. Traditional frame welding conveyor methods have several problems. For example, during transport, the frame is susceptible to vibration and impact, which can lead to deformation, affecting welding quality and overall frame performance. Furthermore, traditional conveyor lines lack flexibility, making it difficult to adapt to changes in the frame's posture and position during transport. This can cause collisions between the frame and the conveyor equipment, reducing production efficiency and increasing costs. Moreover, traditional conveyor lines suffer from poor stability; after prolonged operation, the support structure is prone to deformation or displacement, affecting the accuracy and safety of the conveyor. Therefore, there is an urgent need for an electric vehicle frame welding suspension conveyor line that can effectively reduce vibration and improve flexibility and stability. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide an electric vehicle frame welding suspension conveyor line. This line utilizes designs such as universal joints, buffer structures, guide wheels, and hinge transmissions to achieve automated and stable frame conveying, thereby improving welding quality and production efficiency.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides an electric vehicle frame welding suspension conveyor line, comprising:

[0005] The first support line and the second support line are arranged parallel to each other. The first support line and the second support line are respectively provided with a first conveying channel and a second conveying channel. The two conveying channels are equipped with a suspension mechanism for suspending the vehicle frame.

[0006] The suspension mechanism includes a first carriage that is slidably installed inside a first conveying channel and a second carriage that is slidably installed inside a second conveying channel. The suspension mechanism also includes a suspension rod, the middle of which is connected to the second carriage via a universal joint, and the upper end of which extends into the interior of the first carriage. The interior of the first carriage is equipped with a buffer structure that applies a buffering force to the suspension rod.

[0007] Preferably, a universal ball is fixed in the middle of the suspension rod, and a concave spherical surface adapted to the universal ball is provided in the middle of the second carriage, with the universal ball installed inside the concave spherical surface.

[0008] Preferably, a frame is slidably installed inside the first carriage, a sleeve is provided inside the frame, a convex spherical surface is provided inside the sleeve, the middle part of the convex spherical surface is a curved surface that bends inward, and the two sides of the frame are respectively connected to the inside of the first carriage through a first elastic body.

[0009] Preferably, a slider is slidably installed inside the frame, the sleeve is fixed inside the slider, and the two sides of the slider are respectively connected to the inside of the frame through a second elastic body.

[0010] Preferably, the upper end of the suspension rod extends through the sleeve to the outside, and a gap is left between the convex spherical surface inside the sleeve and the suspension rod.

[0011] Preferably, a first guide wheel is rotatably mounted on both sides of the second carriage, and a second guide wheel is rotatably mounted on both sides of the top. The first guide wheel rolls on the bottom surface of the first conveying channel, and the second guide wheel rolls on the side wall of the first conveying channel.

[0012] Preferably, a third guide wheel is rotatably mounted on both sides of the first carriage, and the third guide wheel rolls on the bottom surface of the second conveying channel.

[0015] Preferably, the two sides of the first support line and the second support line are connected by a fixing strip.

[0016] The beneficial effects of this invention are as follows:

[0017] The adoption of a dual-buffer structure, namely the combination of a first elastomer and a second elastomer, effectively reduces the vibration and impact experienced by the frame during transportation. This protects the integrity of the frame, prevents frame deformation caused by vibration, improves welding quality, and ensures the overall performance of the electric vehicle frame.

[0018] The suspension rod is connected to the second carriage via a swivel joint, allowing the suspension rod to swing at multiple angles. During transport, the frame can adapt to different postures and positional changes, avoiding collisions or damage caused by rigid connections and improving the stability and reliability of the production process.

[0028] The present invention is illustrated below with specific embodiments, but these are not intended to limit the invention.

[0029] Example 1

[0030] like Figures 1-7 As shown in the figure, in this embodiment, an electric vehicle frame welding suspension conveyor line is provided, including a first support line 1 and a second support line 2.

[0031] The first support line 1 and the second support line 2 are arranged parallel to each other vertically. The first support line 1 and the second support line 2 are respectively provided with a first conveying channel and a second conveying channel. The suspension mechanism for suspending the vehicle frame is installed inside the two conveying channels. The suspension mechanism can move along the channel inside the first conveying channel and the second conveying channel inside the first support line 1 and the second support line 2.

[0032] The suspension mechanism includes a first carriage 3 slidably installed inside a first conveying channel and a second carriage 4 slidably installed inside a second conveying channel. The suspension mechanism also includes a suspension rod 5, the middle of which is connected to the second carriage 4 via a universal joint. The upper end of the suspension rod 5 extends into the interior of the first carriage 3. A buffer structure is installed inside the first carriage 3 to apply a buffering force to the suspension rod 5. The suspension rod 5 is used to suspend the vehicle frame and is connected to the second carriage 4 via the universal joint. The buffer structure applies a buffering force to the suspension rod 5, reducing vibration and impact during suspension. This achieves suspended transport of the vehicle frame, and the buffer structure protects the frame from excessive vibration during transport, ensuring the integrity of the frame and welding quality. Simultaneously, the parallel support lines and the double carriage structure make transport more stable.

[0033] A universal ball is fixed in the middle of the suspension rod 5. The middle of the second carriage 4 is provided with a concave spherical surface that is adapted to the universal ball. 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 in the concave spherical surface, so that the suspension rod 5 can swing at multiple angles around the universal ball. This increases the flexibility of the suspension rod 5 and allows the frame to adapt to different postures and position changes during transportation, avoiding collisions or damage caused by rigid connections.

[0034] Example 2

[0035] like Figures 1-4 As shown, based on Embodiment 1, this embodiment provides a multi-directional buffering effect for the suspension rod 5, as detailed below:

[0036] A frame 12 is slidably installed inside the first carriage 3. A sleeve 6 is provided inside the frame 12. The sleeve 6 has a convex spherical surface inside, and the middle part of the convex spherical surface is a curved surface that bends inward. The two sides of the frame 12 are respectively connected to the inside of 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. The first elastic body 7 will deform, 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 reduced more effectively, protecting the structural stability of the conveyor line.

[0037] A slider 8 is slidably installed inside the frame 12, and a sleeve 6 is fixed inside the slider 8. The two sides of the slider 8 are connected to the inside of the frame 12 through a second elastic body 13. When the suspension rod 5 is subjected to force, the slider 8 will slide inside the frame 12, and the second elastic body 13 will deform, absorbing and buffering energy again. Through the double buffer structure of the slider 8 and the second elastic body 13, the buffering performance is further improved, making the frame more stable during transportation and reducing the impact of vibration on the frame.

[0038] The upper end of the suspension rod 5 extends through the sleeve 6 to the outside. There is a gap between the convex spherical surface inside the sleeve 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 sleeve 6. This ensures the movement space of the suspension rod 5, reduces friction and collision, extends the service life of the suspension rod 5 and the sleeve 6, and also helps the buffer structure to play its role.

[0039] The first support line 1 and the second support line 2 are connected on both sides by fixing strips 15, which fix the two together to form a stable structure, enhance the overall stability of the first support line 1 and the second support line 2, ensure the structural strength of the conveyor line, and prevent the support line from deforming or shifting due to external forces during the conveying process.

[0040] Example 3

[0041] like Figures 5-7 As shown, based on Embodiment 1 and Embodiment 2, this embodiment provides an installation method for the first carriage 3 and the second carriage 4, as detailed below:

[0042] The second carriage 4 is rotatably mounted with first guide wheels 10 on both sides and second guide wheels 11 on both sides of the top. 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. By rolling the guide wheels, the second carriage 4 is guided to move smoothly along the first conveying channel, which improves the stability and smoothness of the movement of the second carriage 4, reduces friction with the conveying channel, reduces energy consumption, and also ensures the accuracy of the carriage transport.

[0043] Third guide wheels 14 are rotatably mounted on both sides of the first carriage 3. The third guide wheels 14 roll on the bottom surface of the second conveying channel, guiding the first carriage 3 to move smoothly along the second conveying channel. This enhances the stability and smoothness of the movement of the first carriage 3, and, in conjunction with the guide wheels of the second carriage 4, makes the entire suspension mechanism more stable and reliable during the conveying process.

[0044] The first carriage 3 and the second carriage 4 are both fixed together by a connecting rod 9, making them a whole. During movement, they can maintain their relative position, ensuring the integrity and stability of the suspension mechanism, preventing misalignment or shaking of the first carriage 3 and the second carriage 4 during movement, and ensuring the safe transport of the vehicle frame.

[0045] The second support line 2 is equipped with a hinge that moves along the inside of the second conveying channel. The second carriage 4 is connected to the hinge. The hinge inside the second support line 2 moves along the second conveying channel. 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 conveying channel, providing the power for the movement of the suspension mechanism. This enables the frame to be continuously conveyed on the conveying line, realizing automated frame welding suspension conveying.

[0046] Working principle:

[0047] The working principle of this electric vehicle frame welding suspension conveyor line is based on the coordinated operation of its components. The hinge inside the second support line 2 moves along the second conveyor channel. Since the second carriage 4 is connected to the hinge, the movement of the hinge causes the second carriage 4 to slide within the second conveyor channel. The first carriage 3 and the second carriage 4 are fixed as a whole by the connecting rod 9, so the first carriage 3 also moves synchronously with the second carriage 4 within the first conveyor channel.

[0048] The frame is suspended by suspension rod 5. A universal ball joint in the middle of suspension rod 5 is installed within a concave spherical surface in the middle of the second carriage 4, allowing suspension rod 5 to swing at multiple angles, thus enabling the frame to adapt to different postures and positional changes during transport. When suspension rod 5 is subjected to vibration or impact, its upper end will move accordingly within the first carriage 3. The upper end of suspension rod 5 passes through a sleeve 6, which is installed on a slider 8 inside the frame 12. At this time, suspension rod 5 pushes slider 8 to slide within frame 12, causing the second elastic bodies 13 on both sides of slider 8 to deform, absorbing and buffering some of the energy. Simultaneously, the movement of slider 8 causes frame 12 to slide within the first carriage 3, and the first elastic bodies 7 on both sides of frame 12 also deform, further absorbing and buffering energy, reducing the impact force transmitted from suspension rod 5 to the first carriage 3.

[0049] During movement, the first guide wheels 10 on both sides of the second carriage 4 roll on the bottom surface of the first conveyor channel, and the second guide wheels 11 on both sides of the top roll on the side walls of the first conveyor channel; the third guide wheels 14 on both sides of the first carriage 3 roll on the bottom surface of the second conveyor channel. The rolling of these guide wheels guides the carriage to move smoothly along the conveyor channel, reduces friction with the conveyor channel, and ensures the accuracy and stability of the carriage transport.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate and not 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 modifications or equivalent substitutions can still be made to the present invention without departing from the spirit and scope of the present invention. Any modifications or partial substitutions should be covered within the scope of the claims of the present invention.
