Description

Technical Field

[0001] The utility model belongs to the technical field of ball valve processing, and in particular relates to a ball valve sphere surface processing device. Background Art

[0002] A ball valve is a commonly used valve whose control element consists of a ball, a ball valve seat, a valve stem, a valve stem sleeve, a valve stem nut, and a valve stem brake. Ball valves control the flow of media by rotating the ball. They have the characteristics of simple structure, easy operation, and good sealing performance. They are widely used in the fields of petroleum, chemical industry, water treatment, and pharmaceuticals. Ball valves are mainly used to cut off or regulate the flow of media and can be used in pipeline systems of various media such as water, gas, steam, and oil. The surface of the ball in the ball valve needs to be polished. During the polishing process, the surface of the processing equipment is flat. The debris generated by the contact between the grinding head and the ball will fall directly on the surface of the equipment. Long-term accumulation not only affects the appearance, but also affects the replacement of the ball. Therefore, it is necessary to clean the surface while replacing the ball, which is inconvenient to use. Therefore, the inventors have proposed a ball valve ball surface processing equipment.

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.

[0023] This specific embodiment is a ball valve ball surface processing equipment, and its structural diagram is as follows Figure 1 As shown, it includes a fixed table 2, a clamping assembly 1, a support seat 4 and a grinding mechanism 6. The fixed table 2 has a dust collecting trough 3 inside, and a support seat 4 is provided in the center of the dust collecting trough 3. The outer wall of the support seat 4 and the inner wall of the dust collecting trough 3 are spaced apart, and the clamping assembly 1 is fixedly arranged above the support seat 4; a movable groove 5 is horizontally opened on the upper surface of the fixed table 2, and the grinding mechanism 6 is slidably installed in the movable groove 5.

[0024] Reference Figure 2 The grinding mechanism 6 includes a moving rod 7, a lifting block 10, and a grinding head 12. The moving rod 7 is arranged vertically, and the bottom is slidably installed in the moving groove 5. The top extends out, and the extended part is provided with a slide groove 8. The lifting block 10 is slidably installed inside the slide groove 8. The end face of the lifting block 10 has a mounting hole, and the mounting hole is embedded with a drive motor 11. The output shaft of the drive motor 11 is connected to the grinding head 12. The bottom of the lifting block 10 is fixedly installed with a telescopic cylinder 9. The telescopic cylinder 9 is arranged vertically and embedded in the slide groove 8. A threaded hole is opened through the bottom of the moving rod 7, and a screw is embedded in the moving groove 5. The screw is threadedly connected to the bottom of the moving rod 7.

[0025] Reference Figure 3 、 Figure 4The clamping assembly 1 includes a supporting inner column 17, a clamping block 14, and a rotating motor 16. The bottom of the supporting inner column 17 is fixedly connected to a rotating disk 15, and the rotating disk 15 is rotatably mounted on the upper surface of the support seat 4. The rotating motor 16 is fixedly mounted inside the support seat 4, and the output shaft of the rotating motor 16 is connected to the bottom center of the rotating disk 15. The upper surface of the supporting inner column 17 is threadedly mounted with an adjusting bolt 13, which is vertically arranged and rotatably connected to a lower pressure plate 19 at the bottom. The bottom end surface of the lower pressure plate 19 is protruding with a pressure head 18. Through holes 20 are respectively provided on the outer walls on both sides of the supporting inner column 17, and the clamping block 14 is slidably inserted into the inside of the through hole 20. One end of the clamping block 14 penetrates into the interior of the support and fits with the pressure head 18.

[0026] Working Principle: When in use, first place the sphere on the support inner column 17, then extend the arm through the upper opening of the sphere and turn the adjusting screw bolt. The adjusting screw descends along the thread of the support inner column 17, driving the lower pressure plate 19 to descend. The pressure head 18 at the bottom of the lower pressure plate 19 also descends and squeezes the side wall of the clamping block 14. The clamping block 14 slides along the through hole 20 under the force and presses against the inner wall of the sphere. The two groups of clamping blocks 14 move in opposite directions to form a clamping force on the sphere.

[0027] After the sphere is fixed, the screw inside the displacement moving groove 5 rotates, and the screw is connected to a motor. The screw rotates forward and reversely to drive the moving rod 7, and the moving rod 7 drives the grinding head 12 to approach the outer wall of the sphere. At this time, the telescopic cylinder 9 is extended and retracted, driving the grinding head 12 to rise or fall. Cooperating with the forward and backward displacement of the moving rod 7, the grinding head 12 can move up and down along the outer wall of the sphere, and the rotating motor 16 located inside the support seat 4 is started. The rotating motor 16 drives the rotating disk 15 to rotate, and the rotating disk 15 is forced to drive the supporting inner column 17 to rotate, and then the sphere rotates, and the outer surface is processed during the rotation process. The debris generated by the processing falls directly into the dust collecting tank 3. The concave design of the dust collecting tank 3 has a higher quality of dust collection, and the collected dust in the dust collecting tank 3 can be cleaned uniformly later.
