[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0018] See also Figures 1-4The present invention provides a technical solution: an adjustable lifting device for assembling automobile chassis, comprising a vehicle plate 1, a lifting mechanism 2 is provided on the top of the vehicle plate 1, a placing platform 3 is installed on the top of the lifting mechanism 2, a slide groove 4 is provided inside the placing platform 3, and the spacing between the two placing frames 9 can be adjusted to adapt to chassis with different wheelbases, a movable plate 5 is slidably connected inside the slide groove 4, and a lateral moving component 6 is provided on one side of the placing platform 3 for driving the movable plate 5 to move, a sliding platform 7 is slidably connected inside the movable plate 5, a fixed seat 8 is fixedly connected to the top of the placing platform 3, and a placing frame 9 is provided inside the sliding platform 7 and the fixed seat 8, and two movable grooves 10 are provided inside the placing frame 9, and each movable groove 10 is slidably connected to a supporting fork 11, and the supporting fork 11 is pushed to slide inside the movable groove 10, so that the spacing between the two supporting forks 11 can be adapted to wheelbases of different specifications, thereby improving the flexibility of use.

[0019] Among them, the lateral movement component 6 includes two fixed frames 61, and the two fixed frames 61 are fixed on the outside of the placement table 3. A screw 62 is rotatably connected between the two fixed frames 61. The external thread of the screw 62 is connected to the internal thread block 63, and the internal thread block 63 is fixed to the movable plate 5. One end of the screw 62 passes through the fixed frame 61 and is fixedly connected to the first hand wheel 64. The screw 62 is driven to rotate by the first hand wheel 64. At this time, the screw 62 drives the internal thread block 63 to move, so that the internal thread block 63 drives the movable plate 5 to slide inside the slide groove 4, changing the spacing between the two placement frames 9 to adapt to chassis with different wheelbases.

[0020] Among them, the internal sliding connection of the movable plate 5 is connected to the tooth plate 12, the tooth plate 12 is fixedly connected to one side of the sliding platform 7, and the top of the movable plate 5 is provided with a lifting mechanism 13 for driving the tooth plate 12 to move. The lifting mechanism 13 includes a protective box 131, the protective box 131 is fixed to the top of the movable plate 5, and the internal rotation of the protective box 131 is connected to a worm 132. One end of the worm 132 passes through the protective box 131 and is fixedly connected to a second hand wheel 133. The internal rotation of the protective box 131 is connected to the worm wheel 1 34, the worm wheel 134 is meshed with the worm 132, and a gear 135 is fixedly connected to one side of the worm wheel 134, which is meshed with the toothed plate 12. The worm 132 is driven to rotate by the second hand wheel 133, and the worm 132 drives the worm wheel 134 and the gear 135 to rotate. Since the gear 135 is meshed with the toothed plate 12, the sliding table 7 can be driven up and down under the action of the toothed plate 12 to adjust the height of the placement rack 9, so that it can adapt to uneven ground.

[0021] Among them, the lifting mechanism 2 includes a mounting frame 21, which is fixed to the top of the vehicle plate 1, and has two follower plates 24 symmetrically and slidingly connected inside the mounting frame 21. A two-way screw rod 23 is rotatably connected inside the mounting frame 21, and the two two-way screw rods 23 are both threadedly connected to the two-way screw rod 23. One side of the mounting frame 21 is fixedly connected to the driving motor 22, and the driving motor 22 is fixedly connected to the two-way screw rod 23. A scissor frame 25 is provided on the top of the two follower plates 24, and a connecting frame 26 is installed on the top of the scissor frame 25. The connecting frame 26 is fixed to the bottom of the placement table 3, and the two-way screw rod 23 is driven to rotate by the driving motor 22. Under the action of the two-way screw rod 23, the two follower plates 24 are driven close to each other, thereby causing the scissor frame 25 to shrink toward the center, thereby driving the placement table 3 to move up, thereby realizing the lifting of the chassis, which can replace the traditional multi-cylinder lifting method, avoid the height difference in lifting, and thus ensure the installation accuracy after lifting.

[0022] The four corners of the bottom of the vehicle plate 1 are fixedly connected with moving wheels 14 , and one side of the vehicle plate 1 is fixedly connected with an armrest 15 .

[0023] Among them, two base plates 16 are symmetrically fixedly connected to the bottom of the vehicle plate 1, and the tops of the two base plates 16 are fixedly connected to a cylinder 17. The telescopic end of the cylinder 17 passes through the base plate 16 and is fixedly connected to a support plate 18. The support plate 18 is driven downward by the cylinder 17, thereby lifting the equipment to improve the overall stability.

[0024] In summary: when using this device, first adjust the position of the support fork 11 according to the wheelbase and wheel track of the chassis, push the support fork 11 to slide inside the movable groove 10 to adapt to different front and rear wheel tracks, and drive the lead screw 62 to rotate through the first hand wheel 64. At this time, the lead screw 62 drives the internal thread block 63 to move, so that the internal thread block 63 drives the movable plate 5 to slide inside the slide groove 4, changing the distance between the two placement racks 9 to adapt to chassis with different wheelbases. Then, adjust the height of one group of placement racks 9 according to the height difference of the chassis, and drive the worm 132 to rotate through the second hand wheel 133. At this time, the worm 132 drives the worm wheel 134 to rotate, and when the worm wheel 134 rotates, it drives the gear 1 35 rotates, and since the gear 135 is engaged with the tooth plate 12, the sliding table 7 can be driven up and down by the action of the tooth plate 12 to adjust the height of the placement frame 9. Subsequently, the chassis is lifted by the four placement frames 9, and the equipment and the chassis are moved to the predetermined position through the armrest 15 and the moving wheel 14. The support plate 18 is driven downward by the cylinder 17 to lift the equipment and improve the overall stability. The bidirectional screw rod 23 is driven to rotate by the drive motor 22, and the two follower plates 24 are driven close to each other under the action of the bidirectional screw rod 23, so that the scissor frame 25 is retracted toward the center, thereby driving the placement table 3 to move upward, thereby lifting the chassis and facilitating subsequent assembly.
