[0026] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a butterfly valve stem clamp, comprising: a supporting steel frame 2, with a platform 1 and a platform 4 welded to the top of the supporting steel frame 2; the top of the platform 1 can hold the butterfly valve body 5; the top of the platform 1 is provided with a fitting assembly; the bottom of the platform 1 is provided with a lever assembly; the fitting assembly includes a movable plate 13; the butterfly valve body 5 includes a round rod 51 and a round block 52; the bottom of the movable plate 13 can fit against the top of the round block 52, making the top of the round block 52 flush with the top of the platform 1; the platform 1 has a through-hole mechanism. The movable block 33 and the movable plate 13, when in close contact, allow the lever assembly to move, causing the top of the circular block 52 to rise above the top of the platform 1. The movable plate 13 moves to the top of the circular block 52, pressing it down to clamp and position the butterfly valve body 5, facilitating subsequent rotation of the circular rod 51. The movable plate 13, in contact with the movable block 33, forces the block to move downwards, thereby driving the lever assembly to lift the butterfly valve body 5, increasing the ease of removing it.

[0027] Please see Figure 1 - Figure 4In this embodiment, the top of the platform 1 is provided with a circular groove 101 and a semi-circular groove 16. The circular block 52 can be placed in the circular groove 101, and the circular rod 51 can be placed on the semi-circular groove 16. The circular groove 101 and the circular block 52 are interference-fitted. The interference fit between the circular groove 101 and the semi-circular groove 16 enables the butterfly valve body 5 to be positioned, reducing the occurrence of butterfly valve body 5 offset and avoiding the problem of inaccurate hole position in the later stage. The lever assembly includes a connecting rod 31 rotatably connected below the platform 1. One end of the connecting rod 31 is rotatably connected to a moving block 32, and the other end of the connecting rod 31 is rotatably connected to a moving block 33. The circular groove 101 is provided with a channel 104 for the moving block 32 to pass through, and the top of the platform 1 near the rear side is provided with a channel 102 for the moving block 33 to pass through. 5. The lever action is achieved through the linkage rod 31, enabling the movable plate 13 to perform two functions: pressing the butterfly valve body 5 and driving the butterfly valve body 5 to be pushed out, increasing the convenience of the clamp's use. The top of the movable block 1 32 is provided with a baffle 321, and the top of the movable block 2 33 is provided with a stop block 331. The area of ​​the baffle 321 is larger than the area of ​​the channel 1 104, and the area of ​​the stop block 331 is larger than the area of ​​the channel 2 105. The circular groove 101 is provided with a groove 103 corresponding to the position of the channel 1 104. The groove 103 can accommodate the baffle 321. Through the structure of the baffle 321, the movable block 2 33 is prevented from falling completely out of the channel 1 104. The stop block 331 can effectively prevent the movable block 2 33 from falling out of the channel 2 105, so that the structure of the lever assembly can be used continuously without maintenance.

[0028] Please see Figure 2 - Figure 5In this embodiment, a T-shaped groove 11 runs through the platform 1 from left to right. A T-shaped block 12 slides within the T-shaped groove 11. The top of the T-shaped block 12 is connected to the movable plate 13. The cooperation between the T-shaped groove 11 and the T-shaped block 12 can limit the movement of the movable plate 13. At the same time, the T-shaped groove 11 allows the bottom of the movable plate 13 to fit against the top of the platform 1, thus pressing the round block 52. A connecting block 14 is connected to the top of the movable plate 13. A mounting base 15 is installed on the top of the platform 4. An electric cylinder 17 is installed on the side of the mounting base 15 away from the platform 1. The electric cylinder 17 includes an output rod, and the output rod of the electric cylinder 17 meshes with the connecting block 14. The connecting block 14 is moved via an electric cylinder 17, which in turn moves the moving plate 13, achieving automated drive. The bottom of the front and rear sides of the moving plate 13 has an arc surface 131, and the top of the front side of the stop block 331 has an arc surface 332. The bottom of the platform 11 also has a support block 18. The connecting rod 31 is rotatably connected to the support block 18. The arc surface 131 on the front side of the moving plate 13 better presses the round block 52 into the circular groove 101, avoiding the risk of collision and interference. Simultaneously, the arc surface 131 on the rear side of the moving plate 13 can fit against the arc surface 332, driving the stop block 331 to move the moving block 33 downwards.

[0029] During operation, the butterfly valve body 5 to be processed is manually placed on the circular groove 101. Then, the telescopic rod of the electric cylinder 17 is driven to move forward, forcing the connecting block 14 to move the moving plate 13 forward. After the moving plate 13 contacts the circular block 52, the circular block 52 will be pressed into the circular groove 101 due to the action of the arc surface 131. This completes the clamping and fixing of the butterfly valve body 5. Then, the worker or the robotic arm operates the drilling tool to process the butterfly valve body 5. After the butterfly valve body 5 is processed, the electric cylinder 17 drives the telescopic rod to move backward. The telescopic rod drives the connecting block 14 and the moving plate 13 to move backward. The arc surface 131 on the rear side of the moving plate 13 fits with the arc surface 332 of the stop block 331, causing the moving block 33 to move downward. This causes the linkage rod 31 to move together, making the moving block 32 lift upward. Thus, the stop plate 321 on the moving block 32 can lift the circular block 52 and the circular rod 51 in the circular groove 101.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
