[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 to Figure 4 As shown, this embodiment proposes a suspension device for processing automobile steel plates, including a bottom plate 1, a U-shaped plate 11 is fixedly connected to one side of the upper surface of the bottom plate 1, an upper threaded rod 2 is rotatably connected to the inner top wall of the U-shaped plate 11, a lower threaded rod 21 is fixedly connected to the bottom of the upper threaded rod 2, the thread pitch of the upper threaded rod 2 is greater than the thread pitch of the lower threaded rod 21, the bottom of the lower threaded rod 21 is rotatably connected to the bottom plate 1, a sliding rod 22 is fixedly connected between the U-shaped plate 11 and the bottom plate 1, and the outer wall of the lower threaded rod 21 and the sliding rod 22 is fixedly connected to the bottom plate 1. A lifting sleeve 23 is sleeved on both sides, and a lifting frame 24 is rotatably connected between the two lifting sleeves 23. Connecting rods 25 are rotatably connected to both sides of the lifting frame 24. A motor 26 is fixedly connected to the top of the U-shaped plate 11. The output end of the motor 26 passes through the side wall of the U-shaped plate 11 and is fixedly connected to the upper threaded rod 2. The upper threaded rod 2 and the outer side wall of the sliding rod 22 are jointly sleeved with a limiting mechanism 3. The top of the connecting rod 25 is rotatably connected to the limiting mechanism 3, and the two sides of the top of the lifting frame 24 are slidably connected to a locking mechanism 6.

[0029] The limiting mechanism 3 includes two U-shaped blocks 31, which are respectively threaded and slidably sleeved on the outer side walls of the upper threaded rod 2 and the sliding rod 22. A limiting rod 32 is fixedly connected between the two U-shaped blocks 31. The inner side walls of the two U-shaped blocks 31 are movably hinged with the connecting rod 25. By setting the two U-shaped blocks 31 to be sleeved on the outer side walls of the upper threaded rod 2 and the sliding rod 22, respectively, the limiting rod 32 drives the top ends of the two connecting rods 25 to move in the vertical direction through the two U-shaped blocks 31. Reciprocating motion; two stoppers 4 are arranged inside the U-shaped plate 11, and the two stoppers are respectively fixed between the upper threaded rod and the lower threaded rod 21 and the middle of the slide rod 22. By setting two stoppers 4 respectively fixed to the outer side walls of the lower threaded rod 21 and the slide rod 22, it is prevented that the U-shaped block 31 moves downward to be sleeved with the lower threaded rod 21 and the lifting sleeve 23 moves upward to be sleeved with the upper threaded rod 2; a fixed rod 5 is fixed between the two lifting sleeves 23, and the fixed rod 5 is rotatably sleeved on the lifting frame 24. Inside, the two ends of the fixing rod 5 are fixedly connected to the outer wall of the lifting sleeve 23 to prevent the lifting frame 24 from separating from the two lifting sleeves 23; the locking mechanism 6 includes a plurality of blocks 61, which are slidably connected to the two sides of the top of the lifting frame 24, and the ends of the blocks 61 that are close to each other are tilted. The top of the lifting frame 24 is provided with a slot 62 that is adapted to the block 61, and the block 61 is slidably connected to the inner wall of the slot 62, and one end of the block 61 is fixedly connected to the pull rod 6 3. A spring 64 is fixedly connected between the block 61 and the lifting frame 24. The ends of the pull rods 63 away from the block 61 penetrate the side wall of the lifting frame 24. The ends of the pull rods 63 away from the block 61 are fixedly connected with the pull handles 7. By pulling the pull handles 7 on both sides of the lifting frame 24, the pull rods 63 are driven to move along the card slot 62 to both sides of the lifting frame 24. The pull rods 63 drive the block 61 to move along the card slot 62, so that the block 61 and the steel plate are separated, so that the processed steel plate can be taken out from the lifting frame 24.

[0030] In this embodiment, by pushing the steel plate to move downward along the inner side wall of the lifting frame 24, under the action of the inclined surface of the block 61, the steel plate pushes the block 61 to move along the slot 62 to the two sides of the lifting frame 24 until the steel plate contacts the inner bottom wall of the lifting frame 24. Under the elastic action of the spring 64 itself, the spring 64 pushes the blocks 61 on both sides of the lifting frame 24 to move toward each other along the slot 62, so that one end of the block 61 contacts the upper surface of the steel plate, so that the position of the steel plate in the lifting frame 24 is fixed, and the motor 26 is started. The motor 26 drives the upper threaded rod 2 and the lower threaded rod 21 to rotate through the output end, and the lower threaded rod 21 is lifted. The lowering sleeve 23 and the fixed rod 5 drive the lifting frame 24 to move slowly upward along the slide bar 22, and the upper threaded rod 2 drives the top ends of the two connecting rods 25 to move quickly upward along the slide bar 22 through the U-shaped block 31 and the limit rod 32, so that the distance between the top ends of the connecting rods 25 and the lifting frame 24 is increased, and the two connecting rods 25 drive the lifting frame 24 to rotate around the axis of the fixed rod 5, and the lifting frame 24 drives the steel plate to rotate, and the inclination angle of the steel plate is controlled, which is convenient for workers to control the inclination angle of the steel plate when processing the bottom of the steel plate. Workers can process the bottom of the steel plate from multiple angles, reducing the labor intensity of processing the bottom of the steel plate;

[0031] After the processing is completed, the motor 26 is started, and the motor 26 drives the upper threaded rod 2 and the lower threaded rod 21 to rotate. The upper threaded rod 2 drives the top of the connecting rod 25 to move downward quickly through the U-shaped block 31, and the lower threaded rod 21 drives the lifting frame 24 to move slowly downward through the lifting sleeve 23, so that the distance between the top of the connecting rod 25 and the lifting frame 24 becomes smaller, and the two connecting rods 25 drive the lifting frame 24 to rotate about the axis of the fixed rod 5, and the lifting frame 24 drives the steel plate to rotate so that the bottom of the steel plate is in a horizontal state. By pulling the handles 7 on both sides of the lifting frame 24, the pull rod 63 is driven to move along the slot 62 to both sides of the lifting frame 24, and the pull rod 63 drives the block 61 to move along the slot 62, so that the block 61 and the steel plate are separated, and the processed steel plate is taken out from the lifting frame 24.

[0032] Example 2

[0033] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that both sides of the clamping block 61 are fixedly connected to the limiting blocks 8, and both sides of the inside of the clamping slot 62 are provided with limiting grooves 81 adapted to the limiting blocks 8.

[0034] In this embodiment, when the lifting frame 24 drives the steel plate to move, by setting the limit blocks 8, the clamping block 61 is clamped with the limit groove 81 through the two limit blocks 8, so that the bottom of the clamping block 61 is always in contact with the inner bottom wall of the groove 62, thereby fixing the position of the steel plate inside the lifting frame 24 and making the suspension more stable.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
