DETAILED DESCRIPTION

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] Embodiment: A ball valve clamping mechanism, such as Figure 1 and Figure 2As shown, it includes a base 1, on which a clamping assembly is provided. The clamping assembly includes a positioning base fixed to the base 1 and a movable base movably connected to the base 1. An auxiliary guide rail groove 2 for the movable base to slide is provided on the base 1 located on one side of the positioning base. By relying on the sliding movement of the positioning base and the movable base, convenient clamping and limiting operations can be achieved during the assembly process of the ball valve.

[0018] The movable base includes a slider seat 3 that slides with the auxiliary guide rail groove 2. The slider seat 3 is rotatably connected to the limiting block 4 on the side away from the positioning base. The limiting block 4 maintains a horizontal synchronization state with the slider seat 3 before clamping. A ball valve clamp 5 is provided on the limiting block 4. A valve body positioning groove 6 is provided in the middle of the ball valve clamp 5. When the processing personnel need to assemble and process the ball valve body, they first engage the end of the ball valve body with the valve body positioning groove 6. After the engagement is completed, the limiting block 4 can be flipped to a vertical state; a clamping support block 7 is provided on the slider seat 3. A clamping arc groove 8 is provided in the middle of the clamping support block 7. After the flipping, the limiting block 4 drives the ball valve body from a vertical state to a horizontal state and is buckled with the clamping arc groove 8. The clamping support block 7 realizes a stable support and limit for the ball valve body. An anti-slip pad 24 is provided at the bottom of the clamping arc groove 8, which improves the stable fit between the valve body and the clamping arc groove 8 and reduces the occurrence of active conditions.

[0019] After completing the clamping and limiting cooperation between the valve body and the limiting platform block 4, the processing personnel horizontally slide the slider seat 3 and the valve body as a whole, so that the other end of the ball valve body can quickly achieve calibration clamping and positioning with the positioning base. The positioning base includes a locking block 9 fixed to the base 1, a sleeve ring block 10 movably connected to the locking block 9, and a threaded block 11 threadedly connected to the locking block 9. The middle part of the sleeve ring block 10 is provided with a ball valve sleeve groove 14. As the ball valve body slides horizontally as a whole, the end of the ball valve body is first connected to the ball valve sleeve groove 14. The processing personnel continue to push horizontally until the end of the valve body is fully engaged with the ball valve sleeve groove 14; an adjusting thread groove 12 for threading the thread block 11 is provided in the middle part of the locking block 9, and a valve body screw block 13 is provided at the end of the thread block 11. The valve body screw block 13 and the threaded cavity at the end of the ball valve body can be quickly screwed together. The processing personnel can synchronously operate the rotation of the thread block 11 during the horizontal alignment and feeding process to achieve the spiral locking and limiting of the thread block 11 and the valve body. A knob block 21 is provided at one end of the thread block 11 away from the valve body screw block 13, and a force torsion rod 22 is provided on the knob block 21, which helps to improve the convenience of the processing personnel in the process of synchronous and rapid operation with both hands. The right hand realizes the horizontal feeding of the slider seat 3, and the left hand quickly realizes the rotation and locking of the spiral, and finally completes the clamping and positioning of the ball valve body, ensuring the reliable valve body state of the subsequent processing and assembly process of the valve body. An auxiliary limit block 23 is also provided on the end of the thread block 11 close to the force torsion rod 22, which facilitates the processing personnel to perform the horizontal feeding distance of the thread block 11 part according to the actual specifications of the valve body, and reduces the damage to the valve body structure caused by possible over-tightening.

[0020] Considering that the clamping mechanism, especially the matching clearance of the contact part with the ball valve body, may be worn out after long-term disassembly and assembly, the locking block 9 of the clamping mechanism is provided with an active slot 15 for the sleeve ring block 10 to be inserted into. After long-term use, the processing personnel can realize convenient disassembly, maintenance and replacement. A sleeve hole 16 is provided at one end of the sleeve ring block 10 inserted into the active slot 15, and the groove walls on both sides of the active slot 15 are provided with locking holes 17 matching with the sleeve hole 16. A plug-in rod 18 is inserted into the locking hole 17. The processing personnel only need to The movable disassembly and assembly of the sleeve ring block 10 can be achieved by plugging and pulling out the plug-in rod 18, which ensures stability and reliability during use; at the same time, the ball valve clamp 5 is slidingly connected to the limit block 4, and the limit block 4 is provided with an installation slot 19, and the ball valve clamp 5 is provided with an installation block 20 that cooperates with the installation slot 19. The ball valve clamp 5 is plugged and installed with the limit block 4, which ensures the stable clamping and limiting performance of the ball valve clamp 5, and significantly improves the convenience of disassembly and assembly and maintenance of the end of the ball valve clamp 5.

[0021] After the valve body is processed after the clamping limit, the processing personnel can rotate the threaded block 11 to unscrew the valve body screw block 13, release the clamping limit of the ball valve body, and simultaneously slide the slider seat 3 to the side away from the positioning base, and flip the ball valve body and the limit block 4 to a horizontal state, so that the processing personnel can lift up and partially remove the valve body processing parts from the ball valve clamp 5. An elastic pad 25 is provided on the side of the limit block 4 away from the ball valve clamp 5, which can provide buffering protection for the limit block 4 after it is flipped, thereby reducing the impact between the limit block 4 and the base 1 on the smoothness of disassembly and assembly of the ball valve body.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
