Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
Fig. 1 is a schematic structural diagram of the present invention. As shown in fig. 1, the bending machine has a connecting rod follower mechanism, and the connecting rod follower mechanism is mounted beside a workbench upright post 16 of the bending machine. The connecting rod follow-up mechanism comprises a power mechanism, a connecting rod structure and a rotating platform 8. The power mechanism drives the connecting rod structure to move. The link structure urges the rotary platform 8 to rotate about the first stationary shaft 9. The rotary platform 8 can be rotated to a state parallel to the horizontal plane or to a state forming a set angle with the horizontal plane. The first fixed shaft 9 is positioned at the side of the lower die holder 17 of the bending machine. When the rotary platform 8 rotates to be parallel to the horizontal plane, the rotary platform 8 and the lower die holder 17 are almost at the same height. When the rotating platform 8 needs to rotate to a state of forming a set angle with the horizontal plane, the specific size of the set angle can be set by a technician according to needs, after the rotating platform is bent with a workpiece bent by the bending machine, the tilting angle of the workpiece plane facing one side of the connecting rod follow-up mechanism is the same, and the rotating platform 8 just supports the tilted workpiece plane.
Fig. 2 is a schematic diagram of a link structure and a transmission structure. As shown in fig. 1 and 2, the link structure includes a first link 5, a second link 6, and a third link 7. The first end of the first link 5 rotates about the first fixed shaft 9. The second end of the first connecting rod 5 is connected to the power mechanism and is driven by the power mechanism to move. The first end of the second link 6 is rotatable about a second fixed axis 10. The second end of the second link 6 is rotatably connected to the second end of the third link 7 via a first movable shaft 14. The first end of the third connecting rod 7 is rotatably connected with the bottom surface of the rotating platform 8 through a second movable shaft 12. The middle end of the first connecting rod 5 is rotatably connected with the middle end of the second connecting rod 6 through a third movable shaft 13.
The power mechanism comprises a motor 1 and a speed reducer 2 arranged on an output shaft of the motor 1. A transmission structure is mounted on an output shaft of the speed reducer 2. The transmission structure comprises a driving gear 3 and a sector gear 4. The drive gear 3 meshes with a sector gear 4. The circle center of the sector gear 4 can rotate around the third fixed shaft 11. One corner of the sector gear 4 is rotatably connected with the connecting rod structure through a fourth movable shaft 15.
When the rotary platform 8 needs to rotate from a state parallel to the horizontal plane to a state of forming a set angle with the horizontal plane, the motor 1 drives the speed reducer 2 to rotate, the driving gear 3 rotates clockwise, the sector gear 4 meshed with the driving gear 3 is driven to rotate anticlockwise around the third fixing shaft 11, the second end position of the first connecting rod 5 moves, the first end position of the first connecting rod 5 is relatively fixed, the middle end position of the first connecting rod 5 moves, the middle end position of the second connecting rod 6 moves, the second end of the second connecting rod 6 moves along with the first end position, the third connecting rod 7 rotates clockwise integrally, the bottom surface of the rotary platform 8 is pushed upwards, and the rotary platform 8 rotates around the first fixing shaft 9 to form a state of forming a set angle with the horizontal plane. When the rotating platform 8 needs to rotate from a state of forming a set angle with the horizontal plane to a state of being parallel with the horizontal plane, the rotating direction of the motor 1 is opposite.
