Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 5The utility model provides a quick clamping device for processing pneumatic valve bonnets, comprising a processing table 1, wherein the processing table 1 is rotatably connected to a rotating disk 2 to improve the rotation stability of the rotating disk 2. The rotating disk 2 is connected to a clamping mechanism for clamping the end cover, and the clamping mechanism comprises a plurality of movable plates 4, a plurality of side pressure plates 5, a plurality of springs 1 8, a plurality of T-shaped columns 9, a plurality of upper pressure plates 11, and a plurality of springs 2 14. Four movable plates 4 may be provided, with adjacent angles of 90°. There are also four side pressure plates 5 and upper pressure plates 11 that match them, and a single movable plate 4 corresponds to two T-shaped columns 9. The movable plate 4 is movably connected to the rotating disk 2, the T-shaped column 9 passes through the movable plate 4, the side pressure plate 5 is connected to the end of the T-shaped column 9, the two ends of the spring 1 8 are connected to the T-shaped column 9 and the movable plate 4, the upper pressure plate 11 is movably connected to the movable plate 4, the two ends of the spring 2 14 are connected to the upper pressure plate 11 and the movable plate 4, and the movable plate 4 is connected to a driving mechanism for driving the plurality of movable plates 4 to move back and forth synchronously.

[0023] The clamping mechanism also includes a plurality of vertical slots 13, a plurality of guide posts 15, and a plurality of inclined surfaces 12. The vertical slots 13 are provided on the side of the movable plate 4. The upper pressure plate 11 is slidably connected to the vertical slots 13. The guide posts 15 are used to guide the upper pressure plate 11. The inclined surfaces 12 are provided at the ends of the upper pressure plate 11. When the four movable plates 4 move synchronously toward the center of the rotating disk 2, the side pressure plates 5 press on the outer side of the valve cover, the T-shaped posts 9 slide relative to the movable plates 4, the spring 1 8 is gradually stretched, so that the pressure exerted by the side pressure plates 5 on the valve cover gradually increases, the inclined surfaces 12 slide relative to the top edge of the valve cover, so that the upper pressure plate 11 gradually moves upward, and the spring 2 14 is gradually compressed until the bottom of the upper pressure plate 11 presses against surface a, which is the top surface of the valve cover. At this time, the side pressure plates 5 press against the outer side of the valve cover, thereby achieving full compression and fixation of the valve cover, thereby improving the stability of the valve cover. At this time, the valve cover is in a suitable processing position, which is convenient for subsequent processing.

[0024] The second spring 14 is located in the vertical groove 13, and the second spring 14 is sleeved on the guide post 15, which is fixed in the vertical groove 13 and is slidably connected to the upper pressing plate 11. The coordinated use of the guide post 15 and the vertical groove 13 makes the upper pressing plate 11 stable in lifting and lowering and not easy to tilt or deflect.

[0025] The drive mechanism includes multiple sliding blocks 10, multiple connecting plates 16, electric push rods 17, and lifting blocks 18. The sliding blocks 10 are fixedly connected to the movable plate 4 and are slidably connected to the slide holes 3 provided on the rotating disk 2. The ends of the electric push rods 17 are connected to the rotating disk 2, and the power output end of the electric push rods 17 is connected to the lifting blocks 18. The ends of the connecting plates 16 are axially connected to the sliding blocks 10 and the lifting blocks 18. The electric push rods 17 can drive the lifting blocks 18 to rise and fall, so that the lifting blocks 18 simultaneously apply pressure or thrust to the four connecting plates 16, which can drive the four sliding blocks 10 to reciprocate synchronously, that is, the four movable plates 4 to reciprocate synchronously, facilitating the tightening and loosening of the end caps.

[0026] The lifting block 18 is connected to a rotating mechanism for driving the lifting block 18 to rotate. The rotating mechanism includes a U-shaped seat 6, a motor 7, a rotating shaft 20, and a rotating head 21. The U-shaped seat 6 is connected to the bottom of the processing table 1, and the motor 7 is connected to the U-shaped seat 6. The power output end of the motor 7 is connected to the rotating shaft 20, and the end of the rotating shaft 20 is connected to the rotating head 21. The rotating head 21 matches the connecting groove 22 provided in the lifting block 18. When the end cover is just placed on the top of the rotating disk 2, the lifting block 18 and the positioning column 19 are in a docking state. The positioning column 19 can limit the lifting block 18, prevent the lifting block 18 from rotating, and thus prevent the rotating disk 2 from rotating, thereby improving the stability of the rotating disk 2 and facilitating the placement of the end cover on the top of the rotating disk 2. When the end cap is processed, the electric push rod 17 drives the lifting block 18 to move upward to loosen the end cap. The lifting block 18 is separated from the positioning column 19 and docked with the rotating head 21 separately. The motor 7 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the rotating head 21 to rotate, thereby rotating the lifting block 18, driving the rotation of the rotating disk 2 and the end cap, so as to facilitate comprehensive observation of the end cap and flexible and convenient operation. When the processed end cap is unloaded, the electric push rod 17 drives the lifting block 18 downward again, that is, the lifting block 18 returns to its initial position and docks with the positioning column 19 to limit the lifting block 18 and improve the stability of the rotating disk 2.

[0027] A positioning column 19 is connected to the top of the U-shaped seat 6. The positioning column 19 matches the connecting groove 22. The rotating shaft 20 passes through the positioning column 19. The rotating shaft 20 is rotationally connected to the positioning column 19 to improve the rotation stability of the rotating shaft 20.

[0028] The cross-sections of the connecting groove 22 , the rotating head 21 , and the positioning post 19 are regular polygonal structures.

[0029] Working principle: Place the valve cover on top of the rotating disk 2. The electric push rod 17 drives the lifting block 18 to move downward. The positioning column 19 slides in the connecting groove 22. The lifting block 18 applies a pulling force to the four connecting plates 16 synchronously, causing the four sliding blocks 10 to move synchronously. The sliding blocks 10 drive the corresponding movable plates 4 to move, causing the side pressure plates 5 to press against the outside of the valve cover, and the spring 1 8 to be in an extended state. At the same time, the upper pressure plate 11 presses against the top of the valve cover. At this time, the spring 2 14 is in a compressed state, which can fully lock and fix the valve cover, improve the stability of the valve cover, and the valve cover is in a suitable processing position, which is convenient for subsequent processing operations. When the valve cover is processed, the electric push rod 17 drives the lifting block 18 to move upward. The lifting block 18 applies an upward thrust to the four connecting plates 16 synchronously, causing the movable plate 4 to move back. The side pressure plates 5 and the upper pressure plate 11 are separated from the valve cover, and the valve cover is loosened. The lifting block 18 continues to move upward, so that the lifting block 18 is separated from the positioning column 19 and docked with the rotating head 21 separately. The motor 7 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the rotating head 21 to rotate, thereby driving the lifting block 18 to rotate, which can realize the rotation of the rotating disk 2 and the end cover, facilitates the comprehensive inspection of the end cover, is flexible and convenient to operate, and has strong practicality.
