Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a processing and polishing device for a three-piece bottom-mounted ball valve. Background Technique

[0002] Three-piece ball valves and gate valves belong to the same type of valves. The difference is that its closing part is a sphere, and the sphere rotates around the center line of the valve body to achieve opening and closing. Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Most of their materials are metals. During the production stage, they need to be polished repeatedly to remove burrs, and their surfaces also need to be polished. The existing processing and polishing equipment for three-piece bottom-mounted ball valves has poor integration effect of grinding and polishing, and it is not convenient to replace the grinding cylinder. Therefore, a processing and polishing device for three-piece bottom-mounted ball valves is needed.

[0003] The existing patent document with the technical publication number of CN220481334U provides a ball valve processing and polishing device, including an outer frame shell. A grinding bucket is fixedly connected to the middle position at the bottom inside the outer frame shell. A revolution turntable is installed at the bottom of the upper hydraulic cylinder. The front and rear ends and the left and right sides at the bottom of the revolution turntable are respectively installed with rotation turntables. An installation plate is arranged at the bottom end of the rotation turntable. A grinding material adding and reducing mechanism is arranged inside the grinding bucket. By setting a discharge port, a limiting cylinder, a grinding material support plate, a support ring and a lower hydraulic cylinder, when in use, the lower hydraulic cylinder extends upward to push the grinding material support plate to move upward. The limiting cylinder can make the grinding material support plate move up and down. The grinding material support plate lifts the grinding material particles, and the particles are discharged outwards along the discharge port. The support ring can support the grinding material support plate when it is lowered, realizing the function of facilitating the addition and reduction of grinding materials, and solving the problem that the device does not have the function of facilitating the addition and reduction of grinding materials. However, when the technology of CN220481334U is operating, it cannot effectively improve the integration effect of grinding and polishing of the device, and at the same time, it cannot effectively improve the convenience effect of replacing the grinding cylinder of the device, and it cannot improve the efficiency of inserting and fixing the valve of the device.

[0027] Please refer to Figures 1-5, A processing and polishing device for a three-piece bottom-mounted ball valve. A limiting frame chute 11 is provided at one end of the processing table 1. A tooth shaft frame 12 is installed at the inner end of the limiting frame chute 11. An upper top spring 13 is installed in the middle of the tooth shaft frame 12. A limiting plate ring 14 is installed at the upper end of the upper top spring 13. A connecting plate shaft 15 is installed at the upper end of the tooth shaft frame 12. A pressing and tilting plate 16 is installed at one end of the connecting plate shaft 15. A top connecting shaft 17 is installed at the upper end of the pressing and tilting plate 16.

When the grinding cylinder 9 needs to be replaced after a long time of use, the limiting sleeve 6 can be moved upward in the bearing cylinder hole 5 so that it does not contact the grinding cylinder 9. At the same time, the bearing cylinder hole 5 is rotated to the other side through the connecting column hole 4 of the support cylinder plate 3, and the new grinding cylinder 9 is installed on the cartridge shaft 8. The limiting sleeve 6 is used in the bearing cylinder hole 5 to cover the grinding cylinder 9 and the upper end of the cartridge shaft 8 downward through the force of the lower top spring 7 to limit its movement without affecting the rotation of the grinding cylinder 9.
