Description

Technical Field

[0001] This invention relates to the field of new energy vehicle processing technology, specifically to an assembly table for assembling metal parts for new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] For example, Chinese Invention Patent Publication No. (CN120480580B) discloses an automotive parts assembly equipment. This equipment includes an equipment frame, a worktable on the surface of the equipment frame, an assembly base fixedly mounted on the surface of the worktable, a positioning column fixedly mounted on the surface of the assembly base, a control arm body placed on the support base and the surface of the assembly base, a bushing placed above the mounting hole, and an alignment mechanism on the surface of the positioning column. The alignment mechanism includes a bushing positioning component and a control arm positioning component. The bushing positioning component includes a push plate, a first positioning part, and a first adjustment part. The control arm positioning component includes a cross column, a second positioning part, and a second adjustment part. This invention solves the problem that existing assembly methods cannot accurately control the alignment of the bushing and the mounting hole axis on the control arm surface, the position between the bushing and the mounting hole is prone to offset, and the bushing cannot be efficiently pressed into the mounting hole during pressing assembly, resulting in poor performance.

[0004] However, this patent requires manual support of the parts. When the parts are large and made of metal, it is not easy to lift them. Moreover, lifting with one hand is prone to hand tremors that can cause the parts to shift in position. Lifting with both hands makes it impossible to perform assembly operations. If they are not supported, it is not convenient to position the two parts, resulting in low assembly efficiency and affecting practicality. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an assembly table for assembling metal parts for new energy vehicles. It has the advantages of facilitating the lifting and positioning of parts, allowing workers to free up their hands for assembly work. This solves the problems of the patent where parts need to be manually supported, which is inconvenient for long periods of time when the parts are large and made of metal. Moreover, lifting with one hand is prone to hand tremors that can cause the parts to shift in position, while lifting with both hands makes assembly operations impossible, resulting in low assembly efficiency and affecting practicality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an assembly table for assembling metal parts for new energy vehicles, comprising a worktable, an extension plate fixed to the back of the worktable, a first mounting plate fixed to the upper surface of the extension plate, an assembly mechanism for lifting and assembling parts on the first mounting plate, and a positioning mechanism for positioning and fixing the parts to be assembled on the worktable.

The two connecting rods 419 are located inside the two third sliding openings respectively, and the width of the third sliding opening is adapted to the outer diameter of the connecting rod 419.

[0030] For details, please refer to Figure 4-5 To position and fix the lower parts, the positioning mechanism 5 includes a third motor 501, which is fixed to the lower surface of the worktable 1. The output shaft of the third motor 501 passes through and extends into the interior of the worktable 1, and is fixed with a second gear 502. The outer side of the second gear 502 meshes with a third gear 503. The lower surface of the third gear 503 is rotatably connected to the inner bottom wall of the worktable 1 through a bearing.

[0031] In this embodiment, there are at least two third gears 503, which are symmetrically distributed around the central axis of the second gear 502. The number of second racks 504 is equal to the number of third gears 503, and their positions correspond one-to-one. A third slide rod is fixed on the front inner wall of the worktable 1. The number of third slide rods is equal to the number of second racks 504, and their positions correspond one-to-one.

[0032] It should be noted that the second rack 504 is tilted to the right at a certain angle, and the upper surface of the worktable 1 is provided with multiple fourth sliding openings. The number of fourth sliding openings is equal to the number of the second rack 504, and their positions correspond one-to-one. Multiple third connecting blocks 505 are located inside the multiple fourth sliding openings, and the width of the fourth sliding opening is adapted to the width of the third connecting block 505. The tilt angles of the fixing plate 506, the third sliding rod, and the fourth sliding openings are all the same as the tilt angles of the second rack 504.

[0033] It should be added that the model numbers of the first motor 401, the second motor 405, and the third motor 501 are all 180SG-M27015.

[0034] The working principle of the above embodiments is as follows: (1) First, place the parts to be assembled on the workbench 1, then turn on the third motor 501. The output shaft of the third motor 501 drives the second gear 502 to rotate. The second gear 502 drives all the surrounding third gears 503 to rotate in the same direction, so that all the second racks 504 move towards the center position of the second gear 502 at the same time. The second racks 504 drive the third connecting block 505 to move. The third connecting block 505 drives the fixing plate 506 and the positioning clamp 507 to move, thereby positioning the parts to be assembled to the center. The parts to be assembled are fixed in place to prevent displacement during assembly. After the parts to be assembled are fixed, the second motor 405 is turned on. The output shaft of the second motor 405 drives the first gear 406 to rotate. The first gear 406 drives the first racks 407 on both sides to move, so that the first racks 407 on both sides move relative to each other. The first racks 407 drive the first connecting block 408 to move. The first connecting block 408 drives the support plate 409 to move. The support plate 409 drives the clamping plate 414 to move, thereby clamping and fixing the other parts to be assembled.

[0035] (2) Next, turn on the first motor 401. The output shaft of the first motor 401 drives the threaded rod 402 to rotate. The threaded rod 402 drives the threaded block 403 to move. The threaded block 403 drives the second mounting plate 404 to move, thereby driving the clamped parts to move up and down, replacing manual lifting and improving assembly efficiency. When there is a deviation between the positions of the two parts, press down the handles 420 on both sides at the same time. The handles 420 drive the connecting rod 419 to move. The connecting rod 419 drives the limiting plate 416 to move, so that the magnetic plate 4 When 17 is separated from the adsorption plate 418, the spring 415 is compressed and stores elastic potential energy. After losing its adsorption effect, the position of the second connecting block 413 can be moved through the slide rail 410 and the slider 412, thereby driving the position of the clamping plate 414 to move so that the positions of the two assemblies are aligned. After adjusting the position, the handles 420 on both sides are released, and the spring 415 springs the position of the limiting plate 416 back, so that the magnetic suction plate 417 is re-adsorbed between the adsorption plate 418, thereby keeping the position of the assembly stable.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
