A clamping drive mechanism 11 is provided on the main body 1 of the non-destructive clamping mechanism, and a double-threaded screw 18 is installed in the clamping drive mechanism 11, and the threads on both sides of the double-threaded screw 18 are connected with a clamping adjustment seat 17 through rotational symmetry. The motor positioning plate 15 is screwed and fixed to the motor mounting cover 8, and a connecting plate 16 is further provided under the motor positioning plate 15, and the connecting plate 16 is screwed and fixed to the upper end of the outer shell of the clamping drive mechanism 11. A rotating limit ring 10 with a ball structure is movably engaged between the motor positioning plate 15 and the connecting plate 16. The rotating motor 9 of this structure is a stepping motor. When the rotating motor 9 is started, the connecting plate 17 can be driven 16 rotates to realize the rotation processing of the clamping drive mechanism 11, so that the structure below the clamping drive mechanism 11 rotates, so that the valve can be sprayed evenly during supersonic spraying. A fixing plate 12 is provided at the lower end of the clamping adjustment seat 17, and a positioning seat 20 is provided on the opposite side of the fixing plate 12, and a mounting protective cover 6 is movably engaged on the side of the positioning seat 20, and a clamping plate 5 is fixedly connected and fixed at the other end of the mounting protective cover 6, and a clamping seat 4 is provided on the opposite side of the clamping plate 5. The clamping seat 4 is made of flexible material, and a circular arc groove is provided in the middle of the clamping seat 4. A limiting rod 3 that movably penetrates the limiting plate 21 is welded and fixed on the clamping plate 5, and the other end of the limiting rod 3 is tightly plugged with the mounting protective cover 6. This structure is in the clamping plate 5 through the clamping seat 4 to the end of the valve. After the clamping treatment, the clamping seat 4 can avoid the friction between the clamping plate 5 and the end of the valve, and play a protective role on the valve. At the same time, the clamping plate 5 moves after being subjected to pressure. The limit rod 3 and the positioning seat 20 are used to install the movable limit treatment of the protective cover 6 to ensure the lateral movement of the clamping plate 5 and the tightness of the clamping plate 5 on the end of the valve. By clamping the end of the valve, the outside of the valve can be sprayed. When spraying the inside of the valve, the clamping seat 4 clamps the two sides of the outside of the valve through the arc-shaped groove in the middle. The clamping treatment is performed in the same way. The installation of the protective cover 6 not only protects the internal structure, but also plays a role in movable limiting the clamping plate 5.

When the lifting electric push cylinder 13 is in use, the anti-fouling protective cover 19 is used to protect the piston part to prevent the spraying material from being sprayed onto the lifting electric push cylinder 13. The lower movable end of the lifting electric push cylinder 13 is fixed with a blocking positioning plug 1 by bolts. 4, and the blocking and positioning plug 14 is also made of flexible material. The lifting electric push cylinder 13 of this structure can make the blocking and positioning plug 14 be inserted into the through hole on the side of the valve to achieve stable positioning, while avoiding the shielding of the spraying part.

[0019] Working principle: When using the non-destructive clamping mechanism for supersonic spraying of the valve, firstly, when the valve is sprayed by supersonic spraying equipment, if the valve is sprayed externally, the rotating motor 9 drives the connecting plate 16 under the positioning of the motor positioning plate 15 to drive the clamping drive mechanism 11 to rotate, so that the clamping seat 4 is located at the end position of the valve, and the rotating limit ring 10 plays a role of rotation limiting for the connecting plate 16 and the motor positioning plate 15. The motor mounting cover 8 is used to protect the rotating motor 9, and at the same time plays a role of relatively stable connection between the motor positioning plate 15 and the linear drive mechanism 7. Then the non-destructive clamping mechanism body 1 moves the clamping seat 4 downward through the linear drive mechanism 7, so that the clamping seat 4 is aligned with the end of the valve, and then the lifting electric push cylinder 13 drives the blocking positioning plug 14 to move downward and then plug it into the side through hole of the valve, and the anti-fouling protective cover 19 is used for the lifting electric push cylinder 1 3 plays a protective role, and then starts the clamping drive mechanism 11, and drives the clamping adjustment seats 17 on both sides to move in opposite directions through the rotation of the double-threaded screw 18, so as to adjust the spacing between the fixed plates 12. After the clamping seat 4 is clamped into the end of the valve, the clamping plate 5 is close to the end of the valve, and the clamping plate 5 is active after being subjected to force, and the protective cover 6 is installed to limit the movable position under the positioning of the limit rod 3 and the positioning seat 20, and the limit plate 21 fixes the limit rod 3. When the clamping plate 5 is active, the spring damping shock absorber 2 is compressed under the positioning of the positioning seat 20, so as to realize the clamping and shock absorbing treatment of the clamping plate 5, and at the same time ensure the clamping tightness to avoid damage to the valve. When the internal spraying of the valve is performed, the clamping seat 4 is located at the side of the valve, so that the clamping seat 4 clamps the valve through the arc groove, thereby completing a series of work.
