Abstract
Description
Technical Field
[0001] This invention belongs to the field of electric tricycle frame welding, specifically relating to a welding fixture for electric tricycle frames. Background Technology
[0002] Three-wheeled vehicle frame welding is a key process to ensure the structural strength and safety of the entire vehicle. Traditional manual welding suffers from problems such as low efficiency, poor weld consistency, and large thermal deformation. Modern welding technology uses robotic automated welding, tooling fixture positioning, and digital control to effectively improve the welding quality and production efficiency of the vehicle frame, meeting the needs of large-scale manufacturing.
[0003] Patent CN221833649U discloses a welding fixture for an electric tricycle frame, belonging to the field of electric tricycle manufacturing technology. It includes a support platform, a clamping and fixing assembly, a lifting and positioning assembly, and a pressing mechanism. A rotating frame is rotatably mounted on the upper surface of the support platform, with its front side forming an installation working surface. A welding mechanism is positioned on the front side of the installation working surface for welding operations. The clamping and fixing assembly is located on the upper part of the installation working surface for clamping and positioning, holding the frame in place. The lifting and positioning assembly is located on the lower part of the installation working surface for lifting and supporting operations, lifting the crossbeam to the inside of the frame and positioning it. The pressing mechanism is fixed to the upper end of the rotating frame and performs pressing operations along the height direction of the installation working surface. Based on this mechanism, the frame and crossbeam to be welded are positioned separately, effectively avoiding positioning tilt and facilitating adjustment of the welding position of the crossbeam. Although this device solves the aforementioned problems, the fixing effect during welding is still reduced when the tricycle frame has different shapes and sizes. Summary of the Invention

[0019] like Figure 1 - Figure 7 As shown, one embodiment of the present invention is: an electric tricycle frame welding fixture, including a bottom plate 1, a moving frame 2 fixedly connected to the top of the bottom plate 1, a clamping mechanism 3 provided at the top of the moving frame 2, a bottom support mechanism 4 provided at the bottom of the clamping mechanism 3, and a post-processing mechanism 5 provided on one side of the bottom support mechanism 4.

[0021] The clamping mechanism 3 also includes a third spiral rod 311, a first adjusting plate 312, a second adjusting plate 313, a fixed edge block 314, a sliding plate 315, and a horizontal limit rod 316. The third spiral rod 311 is rotatably connected to the top of the movable base plate 305. The first adjusting plate 312 is movably connected to the outer circumferential surface of the second spiral rod 310. The inner wall of the first adjusting plate 312 is provided with a movable key, which is located in the spiral groove on the outer circumferential surface of the second spiral rod 310. The first adjusting plate 312 is slidably connected to the third spiral rod 311, and the second adjusting plate 313 is movably connected to the outer circumferential surface of the third spiral rod 311. The inner wall of the adjusting plate 313 is provided with a movable key, and the movable key is located in the spiral groove on the outer circumferential surface of the spiral rod 311. The adjusting plate 313 and the spiral rod 310 are slidably connected. The fixed edge block 314 is fixedly connected to the outer wall of the adjusting plate 313. The sliding spring plate 315 is slidably connected to the top of the adjusting plate 313. The horizontal limit rod 316 is fixedly connected to the outer wall of the sliding spring plate 315. The horizontal limit rod 316 and the fixed edge block 314 are slidably connected. The horizontal limit rod 316 and the fixed edge block 314 are connected by a spring, and the spring is sleeved on the outer circumferential surface of the horizontal limit rod 316. The worker feeds the material to be welded into the device through the gap between the moving base plate 305 and the top clamping plate 309. Then, the worker manually rotates the second handle 402 and the first handle 401, which drives the first clamping plate 312 and the second clamping plate 313 to move under the limit and drive of the moving base plate 305 and the third screw rod 311, adjusting them to the appropriate clamping position. Then, by manually rotating the first screw rod 308, the top clamping plate 309 is moved downward through the spiral groove on the circumference of the first screw rod 308. During the downward movement of the top clamping plate 309, the frame material to be welded at the bottom is fixed to accommodate various shapes of tricycle frames and to clamp them stably.
[0022] The bottom support mechanism 4 includes a first handle 401, a second handle 402, and a diagonal fixing rod 403. The first handle 401 is fixedly connected to the outer wall of the third screw rod 311, the second handle 402 is fixedly connected to the outer wall of the second screw rod 310, and the diagonal fixing rod 403 is fixedly connected to the outer wall of the drive block 304.
[0023] The bottom support mechanism 4 also includes a top plate 404, a support clamp 405, and a sliding rod 406. The top plate 404 is fixedly connected to the outer wall of the inclined rod 403, the support clamp 405 is fixedly connected to the outer wall of the top plate 404, and the sliding rod 406 is slidably connected to the inner wall of the support clamp 405.
[0024] The bottom support mechanism 4 also includes a top support plate 407 and an anti-wear wheel 408. The top support plate 407 is fixedly connected to the top of the sliding rod 406, and the anti-wear wheel 408 is rotatably connected to the inner wall of the top support plate 407. The top support plate 407 and the support clamp 405 are connected by a spring, and the spring is sleeved on the outer circumferential surface of the sliding rod 406. The movement of the drive block 304 causes the inclined rod 403 and the top plate 404 to move. During the movement of the top plate 404, the support clamp 405 moves. The movement of the support clamp 405 causes the sliding rod 406 and the top support plate 407 to move. During the movement of the top support plate 407, the anti-wear wheel 408 supports the bottom of the welded part, which facilitates manual loading and unloading of the frame before and after welding.
[0025] Working principle: When the device is in use, the starter motor drives the bidirectional spiral rod 303 to rotate. During the rotation, the bidirectional spiral rod 303 drives the drive block 304 to move under the limit of the limit rod 302 through the bidirectional spiral groove on the circumferential surface. As the drive blocks 304 at both ends of the device converge towards the middle, they drive the top movable base plate 305 to move towards the middle. When the movable base plates 305 at both ends match the size of the material to be welded, the manual person feeds the material to be welded into the device through the gap between the movable base plate 305 and the top clamping plate 309. Then, the manual person rotates the second handle 402 and the first handle 401, thereby driving the first clamping plate 312 and the second clamping plate 313 to move towards the movable base plate 305. The plate 305 moves under the limiting and driving of the spiral rod 311 to adjust it to a suitable clamping position. Then, the spiral rod 308 is manually rotated, and the spiral groove on the circumferential surface of the spiral rod 308 drives the top clamping plate 309 to move downward. During the downward movement of the top clamping plate 309, the frame material to be welded at the bottom is fixed to accommodate various shapes of tricycle frames and to clamp them stably. When the adjusting plate 313 moves, it drives the fixed edge block 314 to move. The fixed edge block 314 drives the sliding plate 315 to fit against the side of the material through the horizontal limit rod 316 and the spring, preventing the material from deviating during the welding and clamping process, which would reduce the welding accuracy.
[0026] During the clamping process of the device, manual rotation of handle 2 402 and handle 1 401 is required to rotate the spiral rod 2 310 and spiral rod 311. This step requires two people to adjust the device on both sides. Due to the large size of the tricycle frame, multiple people are needed to cooperate when loading and unloading. Welding work has certain risks, so the device adopts a two-person operation mode to avoid safety hazards caused by a single person using the device. Two-person operation allows them to supervise and protect each other, thereby preventing safety hazards in the workshop. Alternatively, two power sources can be set up for automatic operation, with one person monitoring. During the clamping and welding unloading process, the drive block 304 moves, causing the inclined rod 403 and the top plate 404 to move. During the movement of the top plate 404, the support clamp 405 moves. The movement of the support clamp 405 causes the sliding rod 406 and the top support plate 407 to move. During the movement of the top support plate 407, the anti-wear wheel 408 supports the bottom of the welded part, which facilitates manual loading and unloading of the frame before and after welding.
[0027] like Figure 1 - Figure 7 As shown, based on the above embodiments, in another embodiment of the present invention, the subsequent processing mechanism 5 further includes an elastic telescopic frame 501, a long horizontal frame 502, and a sliding rod 503. The elastic telescopic frame 501 is fixedly connected to the bottom of the support clamp 405, the long horizontal frame 502 is fixedly connected to the telescopic end of the elastic telescopic frame 501, and the sliding rod 503 is slidably connected to the inner wall of the long horizontal frame 502.
[0028] The subsequent processing mechanism 5 also includes a scraper 504, a fixed crossbar 505, and a sliding block 506. The scraper 504 is fixedly connected to the top of the sliding bar 503, the fixed crossbar 505 is fixedly connected to the inner wall of the moving frame 2, and the sliding block 506 is slidably connected to the outer circumferential surface of the fixed crossbar 505. The long crossbar 502 is connected to the scraper 504 by a spring, and the spring is sleeved on the outer circumferential surface of the sliding bar 503.
[0029] The subsequent processing mechanism 5 also includes a push rod 507 and a dust guide brush 508. The push rod 507 is fixedly connected to the outer wall of the sliding block 506, and the dust guide brush 508 is fixedly connected to the bottom of the sliding block 506. During its movement, the scraper bar 504 scrapes away the slag from the weld seam on the completed side, thereby reducing the time and cost of subsequent manual processing of the weld seam. After welding is completed, the slag will fall to the top of the bottom plate 1. Then, by manually pulling the push rod 507, the sliding block 506 moves under the limit of the fixed crossbar 505. During the movement, the sliding block 506 drives the dust guide brush 508 to move. During the movement, the dust guide brush 508 sweeps the slag on the top of the bottom plate 1 to the outside, which facilitates the subsequent cleaning work.
[0030] Working principle: During the movement of the support clamp 405, the elastic telescopic frame 501 is moved. The movement of the elastic telescopic frame 501 causes the long cross frame 502 and the sliding rod 503 to move. During the movement of the sliding rod 503, the scraper rod 504 at the bottom moves. After the front of the frame is welded, it is manually flipped over to weld the back of the frame. During the movement of the scraper rod 504, the weld slag at the welded side is scraped off, thereby reducing the time and cost of subsequent manual processing of the weld. After welding is completed, the weld slag will fall to the top of the bottom plate 1. Then, by manually pulling the push rod 507, the sliding block 506 moves under the limit of the fixed cross rod 505. During the movement of the sliding block 506, the dust guide brush 508 moves. During the movement of the dust guide brush 508, the weld slag on the top of the bottom plate 1 is swept to the outside, which facilitates the subsequent cleaning work.
