Description

Technical Field

[0001] This utility model relates to the technical field of welding lifting devices, specifically a welding lifting device for automobile frames used in automobile production. Background Technology

[0002] The car frame is the basic component of a car, generally called the chassis frame, on which the engine, transmission, steering system, and body are all fixed. The frame needs to be welded to the engine, transmission, steering system, and body.

[0003] The automotive frame welding lifting device is a specialized piece of equipment used to position and lift frame components. It enables smooth transfer between welding stations, ensuring production continuity. It is used in combination with mechanical structure and hydraulic or electric drive.

[0004] When welding the frame, it needs to be fixed to the lifting device before it can be lifted for use. However, the lifting is usually a straight up and down motion, making it difficult to adjust the angle quickly when needed, which makes the adjustment process quite cumbersome.

[0005] Therefore, a chassis welding lifting device for automobile production is proposed to address the above problems. Utility Model Content

By adding a rotary joint, the vehicle frame can be lifted by controlling the lifting hydraulic cylinder on one side, and the angle can be quickly adjusted by rotating the rotary joint, thereby increasing the flexibility of the vehicle frame during welding and allowing for more angle changes during welding, thus increasing the adaptability during welding.

[0008] Preferably, a plurality of upper damping spring shock absorbers are fixedly connected to the middle of the lifting device body; a support plate is fixedly connected to the top of the upper damping spring shock absorber; the support plate is arc-shaped inside; by adding upper damping spring shock absorbers, the downward speed of the frame after placement can be reduced when the frame is placed, thereby slowing down the contact speed between the frame and the electromagnet. At the same time, the arc-shaped support plate can better match its surface when in contact with the connecting pipe.

[0009] Preferably, a flexible pad is fixed inside the support plate; the flexible pad and the support plate are correspondingly arranged; by adding the flexible pad, gaps can be filled when the frame and the support plate come into contact, making the contact more stable.

[0011] Preferably, the lifting device body has multiple fixed rods rotatably connected to its side wall; a supporting hydraulic cylinder is fixedly connected to the end of each fixed rod; a shim is fixedly connected to the end of each supporting hydraulic cylinder; by using the supporting hydraulic cylinder and fixed rods, the four corner supports can be added after the frame is raised by the multiple supporting hydraulic cylinders, thereby reducing the shaking of the lifting device body during adjustment and increasing its stability.

[0014] 1.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a vehicle frame welding lifting device for automobile production includes a lifting device body 1, with multiple lifting hydraulic cylinders 11 fixedly connected inside the lifting device body 1; a rotary joint 12 is installed on the top of the lifting hydraulic cylinder 11; an electromagnet 13 is fixedly connected to the top of the rotary joint 12; and multiple moving components 14 are provided at the bottom of the lifting device body 1. During operation, the moving components 14 are first used to move the entire lifting device body 1 to the welding position. Then, the multiple lifting hydraulic cylinders 11 are lowered to the same height as the surface of the lifting device body 1, and the vehicle frame is placed on top of the electromagnet 13. Upon contact, the electromagnet 13 can be connected to a power source to heat the vehicle frame. After adsorption and fixation, multiple lifting hydraulic cylinders 11 can be activated to lift the frame. When the frame angle needs to be adjusted, one side of the lifting hydraulic cylinder 11 can be controlled to rise while the others remain stationary, thus raising one side and tilting it. During the rise, the rotary joint 12 will rotate accordingly, which in turn rotates in conjunction with the electromagnet 13. After adjustment, the frame can be welded. By adding the rotary joint 12, the frame can be raised by controlling the lifting hydraulic cylinder 11 on one side, and the angle can be quickly adjusted by rotating the rotary joint 12. This increases the flexibility of the frame during welding, allowing for more angle changes and increasing the adaptability during welding.

[0026] like Figures 1 to 4 As shown, multiple upper damping spring shock absorbers 2 are fixedly connected to the middle of the lifting device body 1; a support plate 21 is fixedly connected to the top of the upper damping spring shock absorber 2; the support plate 21 has an arc-shaped interior; during operation, when placing the frame, it can first contact the support plate 21, so that the frame connecting tube is placed inside the support plate 21. At this time, after the frame is released, the frame will immediately push the support plate 21 to compress the upper damping spring shock absorber 2. When the upper damping spring shock absorber 2 is compressed, the thrust it receives will be gradually eliminated, thereby slowing down the downward movement speed, thus slowing down the contact and impact speed with the electromagnet 13; by adding upper damping spring shock absorbers 2, the downward movement speed of the frame after placement can be reduced, thereby slowing down the contact speed between the frame and the electromagnet 13. At the same time, the arc-shaped design of the support plate 21 can better match its surface when in contact with the connecting tube.

[0027] like Figure 4 As shown, a flexible pad 3 is fixedly connected inside the support plate 21; the flexible pad 3 and the support plate 21 are correspondingly arranged; during operation, after the frame enters the support plate 21, it will first contact the flexible pad 3. When in contact, the flexible pad 3 will deform due to the entry of the frame. When deformed, it will reduce the gap between the frame and the support plate 21, thereby increasing the fit between the support plate 21 and the frame; by adding the flexible pad 3, the gap can be filled when the frame and the support plate 21 are in contact, making it more stable when in contact.

[0028] like Figures 1 to 5 As shown, the moving component 14 includes multiple lower damping spring shock absorbers 4; the lower damping spring shock absorbers 4 and the lifting device body 1 are rotatably connected; a connecting frame 41 is fixedly connected to the bottom of the lower damping spring shock absorber 4; a wheel 42 is rotatably connected to the bottom of the connecting frame 41; during operation, when the lifting device body 1 is moved, the lower damping spring shock absorbers 4 will extend and retract when encountering uneven road surfaces, pushing the connecting frame 41 and sending the wheel 42 into the deepest part of the ground for contact. Thus, after contact, the rapid push of the connecting frame 41 reduces the overall bumps experienced by the lifting device body 1, thereby quickly stabilizing the whole; by adding lower damping spring shock absorbers 4, the slope change of the lifting device body 1 during movement can be reduced by the automatic extension and retraction of the lower damping spring shock absorbers 4, thereby reducing the impact of uneven road surfaces on the lifting device body 1 during movement and increasing stability during movement.

[0029] like Figures 1 to 5 As shown, multiple fixed rods 5 are rotatably connected to the side wall of the lifting device body 1; a supporting hydraulic cylinder 51 is fixedly connected to the end of each fixed rod 5; a pad 52 is fixedly connected to the end of each supporting hydraulic cylinder 51; during operation, when the frame is placed on the lifting device body 1 and the angle is adjusted, the multiple fixed rods 5 can be rotated to move away from the interior of the lifting device body 1. Then, when the fixed rods 5 rotate to their maximum angle, the supporting hydraulic cylinder 51 is activated, causing the supporting hydraulic cylinder 51 to push the pad 52 to contact the ground. After contacting the ground, the multiple supporting hydraulic cylinders 51 provide support, thereby increasing stability when adjusting the angle of the frame; by using the supporting hydraulic cylinders 51 and the fixed rods 5, when the frame is lifted, the multiple supporting hydraulic cylinders 51 can raise it and provide support at the four corners, thereby reducing the overall swaying of the lifting device body 1 during adjustment and increasing its stability.

[0030] like Figures 1 to 2 As shown, a sliding cover 6 is slidably connected inside the lifting device body 1; the sliding cover 6 and the fixing rod 5 are correspondingly arranged; a handle 61 is fixedly attached to the surface of the sliding cover 6; the handle 61 is slidably connected to the lifting device body 1; during operation, after using the fixing rod 5, the fixing rod 5 can be rotated into the lifting device body 1 for storage. After storage, the handle 61 can be pushed to move it down. When moving down, the handle 61 will push the sliding cover 6 down, thereby closing the lifting device body 1. After closing, it can reduce the diffusion of external impurities into the lifting device body 1, thereby reducing damage to the fixing rod 5; by adding the sliding cover 6, after the fixing rod 5 has finished using, it can enter the lifting device body 1 and use the sliding cover 6 to close the lifting device body 1, thus blocking external impurities.

[0031] Working principle: First, the lifting device body 1 is moved to the welding position using the moving component 14. Then, multiple lifting hydraulic cylinders 11 are lowered to the same height as the surface of the lifting device body 1. The frame is then placed on top of the electromagnet 13. After contact, the electromagnet 13 is connected to a power source to attract and fix the frame. Once fixed, the multiple lifting hydraulic cylinders 11 are activated to lift the frame. When the frame angle needs to be adjusted, one side of the lifting hydraulic cylinders 11 can be operated to raise it while the others remain stationary, thus raising one side and tilting it. During the raising, the rotary joint 12 will move accordingly. The frame rotates in conjunction with electromagnet 13. After adjustment, welding can be performed on the frame. When placing the frame, it first contacts the support plate 21, allowing the frame connecting tube to be placed inside the support plate 21. Upon release, the frame immediately pushes against the support plate 21, compressing the upper damping spring shock absorber 2. As the upper damping spring shock absorber 2 compresses, the thrust is gradually eliminated, slowing its downward movement and thus reducing the contact and impact speed with the electromagnet 13. After the frame enters the support plate 21, it first contacts the flexible pad 3. Upon contact, the flexible pad 3... The frame deforms upon entry, reducing the gap between the frame and support plate 21, thus increasing the fit between them. During the movement of the lifting device body 1, the lower damping spring shock absorber 4 extends and retracts when encountering uneven road surfaces, pushing the connecting frame 41 and sending the wheel 42 into the deepest point of contact with the ground. Upon contact, the rapid push of the connecting frame 41 reduces the overall swaying of the lifting device body 1, quickly stabilizing the entire structure. When adjusting the angle after the frame is placed on the lifting device body 1, multiple fixing rods 5 can be rotated to move them away from the interior of the lifting device body 1. Subsequently, when the fixed rod 5 rotates to its maximum angle, the supporting hydraulic cylinder 51 is activated, causing the supporting hydraulic cylinder 51 to push the pad 52 to contact the ground. After contacting the ground, it is supported by multiple supporting hydraulic cylinders 51, thereby increasing stability when adjusting the angle of the frame. After using the fixed rod 5, it can be rotated into the lifting device body 1 for storage. After storage, the handle 61 can be pushed to move it down. When moving down, the handle 61 will push the sliding cover 6 down, thereby closing the lifting device body 1. After closing, it can reduce the diffusion of external impurities into the lifting device body 1, thereby reducing damage to the fixed rod 5.
