Example

[0025] On the basis of embodiment 1, the present invention is as follows Figure 1-Figure 4 As shown, a fixing frame 9 is fixedly connected between the middle ends of both sides of the support plate 1, a mounting plate 10 is fixedly connected to the middle end of the top of the fixing frame 9, a threaded hole is provided on the top of the mounting plate 10, and a rubber ring 15 is fixedly connected to both ends of the piston 16, and the surface of the rubber ring 15 is movably connected to the inner cavity of the air guide cylinder 8, both ends of both sides of the support plate 1 are fixedly connected to the guide block 23, the surface of the rotating shaft 3 is movably connected to the surface of the guide block 23, the bottom of the fixed splint 2 is fixedly connected to the first rubber pad 11, the top of the movable splint 4 is fixedly connected to the second rubber pad 24, both ends of the movable frame 7 are fixedly connected to the reinforcing inclined plate 6, the middle end of the bottom of the first synchronous wheel 20 is fixedly installed with a support shaft 19, and the bottom of the support shaft 19 is movably connected to the middle end of the bottom of the inner cavity of the fixed box 5 through a bearing.

[0026] In this technical solution, the setting of the fixing frame 9, the mounting plate 10 and the threaded holes makes it convenient for personnel to use bolts to install and fix the whole to the external manipulator. The setting of the rubber ring 15 effectively improves the sealing of the contact between the piston 16 and the air guide cylinder 8, and effectively reduces the probability of air leakage between the piston 16 and the air guide cylinder 8. The setting of the guide block 23 achieves the purpose of guiding the rotating shaft 3 and avoids the rotating shaft 3 from tilting during the movement. The setting of the first rubber pad 11 and the second rubber pad 24 can effectively protect the fixed splint 2, the movable splint 4 and the flexible graphite plate during the grasping process, reducing the probability of the surface of the flexible graphite plate being scratched.

[0027] The working principle of the present invention is as follows: when it is necessary to clamp the flexible graphite plate, the bottom of the fixed splint 2 and the fixed suction cup 13 can be in contact with the top of the flexible graphite plate under the drive of the external manipulator, and the first synchronous wheel 20 can be driven to rotate by starting the drive motor 18. The rotation of the first synchronous wheel 20 can drive the second synchronous wheel 22, the rotating shaft 3 and the movable splint 4 to rotate through the synchronous belt 21 until the movable splint 4 is under the flexible graphite plate. After that, the movable frame 7, the fixed box 5, the rotating shaft 3 and the movable splint 4 can be pushed upward by controlling the extension of the hydraulic cylinder 14, so that the movable splint 4 moves and cooperates with the fixed splint 2. It can be in close contact with both ends of the flexible graphite plate, so that the flexible graphite plate can be effectively clamped and fixed. At the same time, during the movement of the mobile frame 7, it can drive the vertical rod 17 and the piston 16 to move. Under the action of the movement of the piston 16, a large negative pressure can be formed between the air guide cylinder 8, the air guide cover 12 and the fixed suction cup 13. Under the action of the negative pressure, the middle end area of ​​the flexible graphite plate can be firmly adsorbed on the bottom of the fixed suction cup 13, and the flexible graphite plate can be effectively adsorbed and fixed, thereby achieving the effect of multiple fixation during the grasping process of the flexible graphite plate, effectively reducing the chance of the flexible graphite plate falling during the grasping process, and facilitating use by personnel.
