Description

Technical Field

[0001] This utility model relates to the field of electric tricycle frame assembly technology, and more specifically, it relates to a rapid assembly welding table for electric tricycle frames. Background Technology

[0002] Electric tricycle frame welding is a crucial process that connects the main frame (composed of core components such as main longitudinal beams and cross beams) with various functional parts (such as battery brackets and motor brackets) through welding. This process ultimately forms a load-bearing structure that supports the entire vehicle. In this process, the positioning and angle adjustment of the main frame are the core links that affect welding efficiency and quality. Workers must first ensure that the frame is stable, and then adjust the operating angle according to different weld positions (such as the inner side, bottom, and top of the frame) in order to successfully complete the welding of parts and the frame. The welding table, as the core equipment for frame positioning and angle adjustment, directly determines the convenience of welding operations.

[0003] However, most existing welding tables for electric tricycle frames use a fixed platform or a simple structure that can only tilt slightly, which is difficult to meet the actual needs of frame welding. On the one hand, the welding table only relies on blocks or temporary ropes on the edge of the platform to fix the frame. During the welding process, the frame is prone to displacement due to factors such as vibration and welding shrinkage, which leads to an increase in the relative position deviation between the welding of subsequent parts and the frame, affecting the overall structural accuracy of the frame. On the other hand, the welding table cannot flexibly adjust the frame. When it is necessary to weld the bottom, inside or other concealed parts of the frame, workers need to frequently bend over, lean over or even squat on the ground to operate, which not only greatly increases the labor intensity, but also easily leads to uneven welds, missing welds and other quality problems due to obstructed vision. It also reduces the efficiency of welding operations and is difficult to adapt to the needs of large-scale production. Utility Model Content

[0004] (a) Technical problems to be solved In view of the above situation and to overcome the defects of the prior art, this utility model provides a rapid assembly welding table for electric tricycle frames, which aims to solve the problems in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this application provides the following technical solution: a rapid assembly welding table for an electric tricycle frame, comprising a fixed plate and an adjusting frame. An adjusting plate is slidably connected inside the adjusting frame. A hydraulic rod is fixedly connected to the inner wall of the adjusting frame. Ball bearings are fixedly connected to the inner walls of both the fixed plate and the adjusting plate. A first rotating shaft and a second rotating shaft are fixedly connected to the inner rings of the two ball bearings, respectively. A stepper motor is fixedly connected to the right side of the adjusting plate via bolts. A rotating disk is fixedly connected to the ends of the first and second rotating shafts that are close to each other. Multiple reset cylinders are fixedly connected to the inner wall of each rotating disk. Nine movable rods are slidably connected inside each reset cylinder. A reset spring and a damper are fixedly connected together with the inner wall of each reset cylinder at the end of each movable rod near the reset cylinder. A rectangular clamping plate is fixedly connected to the end of each movable rod away from the reset cylinder.

[0006] The present invention is further configured such that the telescopic end of the hydraulic rod is fixedly connected to the right side of the adjusting plate, the right end of the second rotating shaft extends through to the right side of the adjusting plate, and the output end of the stepper motor is fixedly connected to the right end of the second rotating shaft.

[0007] The present invention is further configured such that the bottom surface of the fixed plate and the bottom surface of the adjusting frame are both fixedly connected to a base, and the upper surface of the base is in contact with the bottom surface of the adjusting plate.

[0008] The present invention is further configured such that each of the dampers is located inside the reset spring, and the number of rectangular clamping plates on the outer side of each reset cylinder is nine and the whole is in the shape of a magic square.

[0009] The present invention is further configured such that annular grooves are provided on the sides of the fixed plate and the adjusting plate that are close to each other, and an auxiliary rod is slidably connected inside each annular groove. The outer surface of the end of each auxiliary rod away from the rotating disk is spherical. Annular fixing frames are fixedly connected to the sides of the two rotating disks that are far from each other, and the end of each auxiliary rod close to the rotating disk is fixedly connected to the outer surface of the annular fixing frame.

[0010] (III) Beneficial Effects Compared with the prior art, the beneficial effects of this utility model are: 1. The rotating disc's inner wall has a reset cylinder that works with the movable rod. The movable rod can slide inside the reset cylinder. The reset spring and damper can elastically buffer the movement of the movable rod, causing the rectangular clamping plate, which is shaped like a magic square, to fit the tricycle frame of different shapes. This clamps the frame from multiple directions, preventing the frame from shifting due to fixing only with blocks or ropes. At the same time, the hydraulic rod pushes the adjusting plate to slide inside the adjusting frame. The distance between the two rotating discs can be adjusted according to the frame size to adapt to different frame specifications, ensuring stable frame positioning, improving the overall structural accuracy of the frame, and solving the problem of unstable positioning of existing welding stations. 2. A stepper motor drives the second rotating shaft to rotate, and ball bearings work together to make the first and second rotating shafts synchronously drive the rotating disk to rotate, achieving 360° angle adjustment of the frame. This eliminates the need for workers to frequently adjust their posture, reducing labor intensity. The rectangular clamping plate of the magic square can always stably clamp the frame, while the auxiliary rod slides in the annular groove. Together with the annular fixing frame, it enhances the rotational stability of the rotating disk, ensuring a clear view during welding, reducing problems such as uneven welds and missed welds, improving welding efficiency, meeting the needs of large-scale production, and solving the problem of inconvenient angle adjustment of existing welding tables.

[0016] Please see Figures 1-4The system includes a fixed plate 2 and an adjusting frame 8. An adjusting plate 9 is slidably connected inside the adjusting frame 8. A hydraulic rod 7 is fixedly connected to the inner wall of the adjusting frame 8. Ball bearings 11 are fixedly connected to the inner walls of both the fixed plate 2 and the adjusting plate 9. A first rotating shaft 10 and a second rotating shaft 12 are fixedly connected to the inner rings of the two ball bearings 11, respectively. A stepper motor 6 is fixedly connected to the right side of the adjusting plate 9 by bolts. A rotating disk 3 is fixedly connected to the ends of the first rotating shaft 10 and the second rotating shaft 12 that are close to each other. Multiple reset cylinders 4 are fixedly connected to the inner wall of each rotating disk 3. Nine movable rods 13 are slidably connected inside each reset cylinder 4. A reset spring 17 and a damper 18 are fixedly connected to the end of each movable rod 13 that is close to the reset cylinder 4 together with the inner wall of the reset cylinder 4. A rectangular clamping plate 5 is fixedly connected to the end of each movable rod 13 that is away from the reset cylinder 4.

[0017] Specifically, the adjusting plate 9 inside the adjusting frame 8 is slidable, and the hydraulic rod 7 is fixed to the inner wall of the adjusting frame 8, which can push the adjusting plate 9 to move. The ball bearings 11 on the inner wall of the fixed plate 2 and the adjusting plate 9 respectively support the first rotating shaft 10 and the second rotating shaft 12. The stepper motor 6 is fixed to the right side of the adjusting plate 9 and can drive the second rotating shaft 12 to rotate. The first rotating shaft 10 and the second rotating shaft 12 are respectively connected to the rotating disk 3. The reset cylinder 4 on the inner wall of the rotating disk 3 allows the movable rod 13 to slide. The reset spring 17 and the damper 18 between the movable rod 13 and the reset cylinder 4 can buffer the movement of the movable rod 13. The movable rod 13 is connected to the rectangular clamping plate 5, which can initially realize the clamping and rotation adjustment of the frame, solving the problem of the traditional welding table having no adjusting clamping structure.

[0018] Please see Figures 1-4 The telescopic end of the hydraulic rod 7 is fixedly connected to the right side of the adjusting plate 9, the right end of the second rotating shaft 12 extends through to the right side of the adjusting plate 9, and the output end of the stepper motor 6 is fixedly connected to the right end of the second rotating shaft 12.

[0019] Specifically, the extension end of the hydraulic rod 7 is connected to the adjustment plate 9. The extension and retraction of the hydraulic rod 7 can drive the adjustment plate 9 to slide stably within the adjustment frame 8, adjusting the distance between the two rotating disks 3 to adapt to different sizes of frames. The second rotating shaft 12 passes through the adjustment plate 9 and is connected to the output end of the stepper motor 6. When the stepper motor 6 is started, it can drive the second rotating shaft 12 to rotate, which, together with the first rotating shaft 10, makes the two rotating disks 3 rotate synchronously, realizing the adjustment of the frame angle. This avoids workers manually adjusting the frame position and solves the problem of the welding table angle adjustment relying on manual labor.

[0020] Please see Figures 1-4 The bottom surface of the fixed plate 2 and the bottom surface of the adjusting frame 8 are both fixedly connected to the base 1, and the upper surface of the base 1 is in contact with the bottom surface of the adjusting plate 9.

[0021] Specifically, the bottom surfaces of the fixed plate 2 and the adjusting frame 8 are connected to the base 1. The base 1 provides stable support for the entire welding table and prevents the welding table from shaking during use. The upper surface of the base 1 contacts the bottom surface of the adjusting plate 9, which can provide auxiliary support for the sliding of the adjusting plate 9 and prevent the adjusting plate 9 from tilting due to uneven force when sliding, thus ensuring that the adjusting plate 9 moves smoothly.

[0022] Please see Figures 1-4 Each damper 18 is located inside the return spring 17, and there are nine rectangular clamping plates 5 on the outer side of each return cylinder 4, which are arranged in a cube shape.

[0023] Specifically, the damper 18 is located inside the return spring 17 and works in conjunction with the return spring 17 to slow down the sliding speed of the movable rod 13 and prevent the movable rod 13 from causing the rectangular clamping plate 5 to move quickly and impact the frame. The nine rectangular clamping plates 5 on the outside of each return cylinder 4 are distributed in a magic square pattern, which can fit the frame surface from multiple directions, enhance clamping stability, prevent the frame from shifting during welding, and solve the problems of unstable clamping and easy damage to the frame in traditional welding stations.

[0024] Please see Figures 1-4 Annular grooves 16 are provided on the side of the fixed plate 2 and the adjusting plate 9 that are close to each other. An auxiliary rod 14 is slidably connected inside each annular groove 16. The outer surface of the end of each auxiliary rod 14 away from the rotating disk 3 is spherical. Annular fixing frames 15 are fixedly connected to the side of the two rotating disks 3 that are far from each other. The end of each auxiliary rod 14 that is close to the rotating disk 3 is fixedly connected to the outer surface of the annular fixing frame 15.

[0025] Specifically, the annular groove 16 of the fixed plate 2 and the adjusting plate 9 provides a sliding space for the auxiliary rod 14. The end of the auxiliary rod 14 away from the rotating disk 3 is spherical, which can reduce sliding friction. The end of the auxiliary rod 14 near the rotating disk 3 is connected to the annular fixing frame 15, which is fixed to the side of the rotating disk 3. When the rotating disk 3 rotates, it drives the annular fixing frame 15 and the auxiliary rod 14 to move synchronously. The sliding of the auxiliary rod 14 in the annular groove 16 can enhance the rotational stability of the rotating disk 3, avoid the shaking of the rotating disk 3 during rotation and affect the welding accuracy, and solve the problem of instability of the rotational structure of the traditional welding table.

[0026] Working principle: During the welding of the electric tricycle frame, the hydraulic rod 7 is activated to push the adjusting plate 9 to slide within the adjusting frame 8, adjusting the distance between the two rotating discs 3 to fit the frame size. The adjusting plate 9 is supported by the base 1 during sliding to prevent tilting. The frame is then placed between the two rotating discs 3. The movable rod 13 inside the return cylinder 4 on the inner wall of the rotating disc 3 slides under the action of the return spring 17 and the damper 18, causing the rectangular clamping plates 5, arranged in a magic square pattern, to conform to and clamp the frame from multiple directions. The damper 18 slows down the movement speed of the movable rod 13 to prevent impact on the frame. The step on the right side of the adjusting plate 9 is then activated. The motor 6 drives the second rotating shaft 12 to rotate. This, in conjunction with the first rotating shaft 10 supported by the ball bearings 11 on the inner wall of the fixing plate 2 and the adjusting plate 9, causes the two rotating disks 3 to rotate synchronously, enabling 360° angle adjustment of the chassis. When the rotating disk 3 rotates, the auxiliary rod 14 connected to the annular fixing frame 15 on its side slides in the annular groove 16 of the fixing plate 2 and the adjusting plate 9. The spherical end of the auxiliary rod 14 reduces friction and enhances the rotational stability of the rotating disk 3, achieving stable clamping of the chassis and flexible angle adjustment. This solves the problems of unstable positioning and inconvenient angle adjustment in traditional welding stations, improving welding efficiency and quality.
