Description

Technical Field

[0001] The invention relates to the technical field of polishing devices, in particular to an inner cavity polishing device for valve manufacturing. Background Art

[0002] A valve is a device used to control the direction, pressure and flow of a fluid in a fluid system. It is a device that allows the medium (liquid, gas and powder) in piping and equipment to flow or stop and control its flow. During the valve processing and production process, the inner cavity of the valve's flow pipe is usually polished to prevent the fluid from causing excessive resistance during circulation. In this case, the inner cavity of the valve needs to be polished.

[0003] The current polishing device has certain shortcomings:

[0004] 1. When polishing the valve, the valve must be installed on the operating table. However, after polishing one side, the valve needs to be loosened and changed sides, which wastes time during polishing and delays work efficiency.

[0005] 2. When grinding the inside of the valve, since the diameter of the grinding block is different from the diameter of the inner cavity of the valve, the grinding head needs to be moved back and forth manually so that the grinding block contacts and grinds the inner cavity, which increases the workload of the operator;

[0006] 3. At the same time, a large amount of debris will be generated during grinding, and the debris will remain inside the valve for accumulation, causing a certain impact on the subsequent use of the valve. In addition, a large amount of heat will be generated in the inner cavity of the valve, and the heat will accelerate the wear of the grinding block, resulting in a reduction in the service life of the grinding block.

The water flowing out of the water outlet pipe is sprayed toward the grinding area as the grinding block moves, flushing the debris, and cooling the grinding block at the same time, thereby increasing the service life of the grinding block.

[0042] Embodiment 1, as Figure 1-4 As shown, when half of the inside of the valve is polished, the first gear 4 is rotated so that the first gear 4 drives the outer gear ring 206 meshing with it to rotate, and the outer gear ring 206 drives the annular frame 201 to slide stably inside the arc guide rail 7, so that the annular frame 201 rotates 180 degrees, and the other end of the valve is facing the polishing area, and then the drive motor 11 is turned on to drive the polishing block 308 through a series of transmissions to polish the other end of the valve cavity.

When the grinding block 308 performs a circular motion, the grinding block 308 moves back and forth inside the longitudinal groove, and at the same time drives the transmission plate 16 to move left and right. The transmission plate 16 pulls the two groups of water outlet pipes 13 to swing back and forth around the external water pipe, and the water outlet of the water outlet pipe 13 points to the grinding area, so that the water outlet pipe 13 can accurately spray water to the grinding area.

[0044] Working principle: First, place the valve on the side where the two sets of arc-shaped clamping plates 202 are close to each other, and rotate the two sets of threaded rods 204 at the same time. Under the action of the threads of the two sets of internal threaded sleeves 205, the two sets of threaded rods 204 drive the two sets of arc-shaped clamping plates 202 to approach each other to clamp the valve. Then turn on the drive motor 11 to drive the second gear 15 to rotate through the output shaft. The second gear 15 rotates on the outside of the inner gear ring 303 and revolves around it at the same time, thereby driving the connecting sleeve 302 to rotate on its own and revolve around the inside of the support groove 309, driving the grinding block 308 to rotate on its own and revolve around it at the same time, and then drive the movable plate 306 and the connecting sleeve 302 to move toward the inner cavity of the valve through the two sets of electric push rods 305, so that the grinding block 308 grinds the inner cavity of the valve in all directions.

[0045] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention.
