Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0016] Please see Figures 1 to 4 This utility model provides a technical solution: a lifting mechanism for an automobile production conveyor line, comprising: a base frame 1 and a lifting frame 2, the lifting frame 2 being located at the upper end of the base frame 1; a rotating rod 4 is rotatably connected to the front and rear sides of one end of the base frame 1 via mounting blocks 6; a rotating rod 5 is rotatably connected to the front and rear sides of the lower end of the lifting frame 2 via mounting blocks 6; the end of the rotating rod 4 away from the mounting blocks 6 is slidably connected to the lower end of the lifting frame 2; the end of the rotating rod 5 away from the mounting blocks 6 is slidably connected to the inner wall of the base frame 1; and the rotating rod 5 and the rotating rod 4 are slidably connected to the inner wall of the base frame 1. The rods 1 and 4 are arranged in a cross pattern. One end of the mounting block 6 is fixed to the side wall of the base frame 1 and the lifting frame 2, and the other end is rotatably connected to the rotating rod 1 and the rotating rod 2 5. Tracks 3 are fixedly installed on the front and rear side walls of the base frame 1 and the lifting frame 2. Rollers 7 are rotatably connected to the ends of the rotating rods 1 and 2 5 away from the mounting block 6. The rollers 7 are located inside the track 3. When the rotating rods 1 and 2 5 rotate, one end of the rotating rods 1 and 2 5 rolls inside the track 3 through the rollers 7, thereby realizing the lifting and lowering of the lifting frame 2.

[0017] A driving component is installed between the two rotating rods 25. The driving component is used to drive the two rotating rods 25 to move within the base frame 1. The driving component includes a moving rod 8, a threaded rod 10, and a drive motor 12. The moving rod 8 is fixedly installed between the two rotating rods 25 and on the side close to the roller 7. A threaded sleeve 9 is fixedly installed on the side wall of the moving rod 8. The threaded sleeve 9 penetrates the side wall of the moving rod 8. When the moving rod 8 moves, it can move the two rotating rods 25 synchronously.

[0018] The threaded rod 10 is rotatably installed inside the bottom frame 1. One end of the threaded rod 10 is rotatably connected to the inner wall of one end of the bottom frame 1 through a bearing seat. The other end of the threaded rod 10 is rotatably connected to a support block through a bearing. The support block is fixed inside the bottom frame 1. The threaded rod 10 is rotatably installed inside the bottom frame 1. The outer wall of the threaded rod 10 is threadedly connected to the inner wall of the threaded sleeve 9. When the threaded rod 10 rotates, it can drive the threaded sleeve 9 to move with the moving rod 8, thereby driving the two rotating rods 25 to move synchronously, realizing the lifting and lowering of the lifting frame 2.

[0019] The drive motor 12 is fixedly installed on the inner end of the base frame 1. Steering gears 11 are fixedly installed on both the output end of the drive motor 12 and the outer wall of the threaded rod 10. The outer walls of the two steering gears 11 are meshed together. The drive motor 12 is a servo motor, capable of driving the steering gears 11 to rotate in both directions. When the steering gears 11 rotate, they drive the threaded rod 10 to rotate. The threaded rod 10 drives the threaded sleeve 9 to move the moving rod 8. When the moving rod 8 moves, it moves the two rotating rods 2 and 5 synchronously, thus achieving the lifting and lowering of the lifting frame 2. Several rotating rollers 13 are evenly installed on the inner end of the lifting frame 2. A conveyor belt 14 is installed at one end of the lifting frame 2 at an angle. This device is placed on one side of the automotive parts conveying line. The lifting frame 2 is lowered first, so that the outer end of the conveyor belt 14 contacts the ground. The automotive parts are conveyed into the lifting frame 2 by the conveyor belt 14. The rotating rollers 13 place the automotive parts into the lifting frame 2 in sequence. Then, the drive motor 12 is started to lift the lifting frame 2 and the automotive parts to the parts entrance of the automotive parts conveying line, so that the parts can be conveyed to the automotive parts conveying line.

[0020] The lifting frame 2 is open at one end near the conveyor belt 14. A sliding hole 15 is provided on the side wall of the lifting frame 2 near the conveyor belt 14. A baffle 18 is slidably inserted into the sliding hole 15. An electric push rod 17 is fixedly installed at the lower end of the baffle 18. A fixed frame 16 is fixedly installed at the lower end of the electric push rod 17. The upper end of the fixed frame 16 is fixedly installed on the outer wall of the lifting frame 2 on both the front and rear sides. The electric push rod 17 can drive the baffle 18 to slide in the sliding hole 15 to block the lifting frame 2 and prevent the car parts from rolling and slipping during lifting.

[0021] When this device is working, the lifting frame 2 is first lowered so that the outer end of the conveyor belt 14 contacts the ground. The car parts are then conveyed into the lifting frame 2 by the conveyor belt 14. The car parts are then placed in the lifting frame 2 by the rotating roller 13. The electric push rod 17 is activated to drive the baffle 18 to block the parts. Then the drive motor 12 is activated to lift the lifting frame 2 and the car parts to the parts entrance of the car parts conveyor line, so that the parts can be conveyed to the car parts conveyor line.
