Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to a polishing device for valve plate processing. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. During valve production, the valve plate is polished as needed. A search revealed a patent with publication number CN219725738U that discloses a valve plate polishing device. When the valve plate is clamped and polishing is to be performed, polishing liquid is sprayed from the top using a water pipe. This method tends to scatter the polishing debris and cool the polishing dam, but this cooling method is relatively slow and the cooling effect on the polishing block is poor. Furthermore, the polishing liquid easily splashes, contaminating the operating environment. Therefore, a valve plate polishing device with good polishing cooling effect, splash prevention, and improved operating environment cleanliness is designed. Utility Model Content

[0015] Compared with the prior art, this utility model provides a polishing device for valve plate processing, which has the following features:

[0016] Beneficial effects:

[0017] This valve plate polishing equipment features a valve plate clamping mechanism for easy clamping and fixing of the valve plate onto the operating table. A hollow polishing roller, adjustable in height and rotation, surrounds the valve plate for polishing. Because the hollow polishing roller can rotate circumferentially around the operating table, it can polish the fixed valve plate circumferentially. A liquid supply mechanism allows for easy replenishment of coolant into the hollow polishing roller, ensuring that coolant is discharged from multiple outlets while the roller rotates and polishes, cooling both the polished area and the entire hollow polishing roller. A shield prevents coolant splashing, improving the cleanliness of the operating environment. This method also provides better localized cooling during polishing. This valve plate polishing equipment offers excellent cooling performance, prevents splashing, and enhances the cleanliness of the operating environment. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1-5 A polishing device for valve plate processing includes an operating table 1, a valve plate clamping mechanism on the operating table 1, and a hollow polishing roller 3 that can rotate circumferentially around the center of the operating table 1 on the top of the operating table 1. The hollow polishing roller 3 can be raised and lowered. The hollow polishing roller 3 has multiple water outlets 4 circumferentially opened. At the same time, a shielding cover 20 is provided above the hollow polishing roller 3 to block the multiple water outlets 4 on the upper side. It also includes a polishing drive mechanism for driving the hollow polishing roller 3 to rotate and a liquid supply mechanism for supplying polishing liquid to the hollow polishing roller 3.

[0027] Specifically, it also includes a rotating seat 6 that can rotate circumferentially around the outside of the operating table 1. A hanger 7 is fixedly installed on the top of the rotating seat 6. A lifting frame 8 is slidably connected to the top of the hanger 7 via a lifting mechanism. The hollow polishing roller 3 is laterally rotatably connected to the lifting frame 8. The polishing drive mechanism and the liquid supply mechanism are both set on the lifting frame 8. The shield 20 is fixedly installed on the lifting frame 8. The rotating seat 6, which can rotate circumferentially around the outside of the operating table 1, facilitates the circumferential rotation of the hanger 7 along the outside of the operating table 1. The lifting mechanism facilitates the lifting and adjusting of the hollow polishing roller 3 and the shield 20 to meet the polishing needs of valve plates of different thicknesses and to facilitate the clamping of the valve plates by the valve plate clamping mechanism.

[0028] Specifically, it also includes a circumferential rotating mechanism that drives the rotating seat 6 to rotate around the operating table 1. The circumferential rotating mechanism includes a gear ring 12 and a gear 13. The gear ring 12 is fixedly mounted on the operating table 1, and the gear 13 is rotatably connected to the rotating seat 6. The gear 13 meshes with the gear ring 12. A circumferential motor 14 for driving the gear 13 to rotate is also fixedly mounted on the rotating seat 6. When the circumferential motor 14 is started, the output shaft of the circumferential motor 14 rotates, thereby driving the gear 13 to rotate. Through the meshing of the gear 13 with the gear ring 12, the rotating seat 6 is driven to rotate around the operating table 1.

[0029] Specifically, the lifting mechanism includes a lifting drive cylinder 9 that is vertically fixedly installed on the top of the hanger 7. The bottom output end of the lifting drive cylinder 9 is fixedly connected to the top of the lifting frame 8. When the lifting drive cylinder 9 is started, the output shaft of the lifting drive cylinder 9 extends and retracts, which facilitates the lifting frame 8 to perform lifting operations.

[0030] Specifically, the polishing drive mechanism includes a polishing motor 10 fixedly mounted on the lifting frame 8. The output shaft of the polishing motor 10 is connected to the hollow polishing roller 3 via a transmission assembly 11. Furthermore, the transmission assembly 11 can be a sprocket and chain or a belt and pulley transmission form, preferably a sprocket and chain transmission form.

[0031] Specifically, the liquid supply mechanism includes a water pipe 5 fixedly installed on the lifting frame 8, with one end rotating and sealingly passing through the hollow polishing roller 3, and a valve installed on the water pipe 5 to connect the water pipe 5 to the municipal water pipe network. When the valve is opened, coolant is sent into the hollow polishing roller 3 through the water pipe 5.

[0032] Specifically, the valve plate clamping mechanism includes four sets of limiting clamping wheels 2 mounted on the top of the operating platform 1. The bottom of the operating platform 1 is equipped with a clamping adjustment assembly that moves two sets of limiting clamping wheels 2 on both sides towards the center. The clamping adjustment assembly includes a bidirectional screw 17 rotatably connected to the bottom of the operating platform 1. Two slide bars 16 symmetrically engage with the two sides of the bidirectional screw 17 and slide in a guide-like manner with the bottom of the operating platform 1. The four sets of limiting clamping wheels 2 are rotatably connected to the two ends of the two slide bars 16. At least two guides are provided on the operating platform 1 for the feeding and movement of the limiting clamping wheels 2. A clamping motor 18 is fixedly installed at the bottom of the operating table 1 via the slot 15. Both the output shaft of the clamping motor 18 and the bidirectional screw 17 are fixedly mounted with bevel gears 19, and the two bevel gears 19 mesh with each other. When the clamping motor 18 is started, the output shaft of the clamping motor 18 rotates clockwise or counterclockwise. Through the meshing of the two bevel gears 19, the bidirectional screw 17 is driven to rotate counterclockwise or clockwise, which in turn drives the two slide bars 16 to move to the sides or to the center, and in turn drives the four sets of limit clamping wheels 2 on both sides to move to the sides or to the center.

[0033] Specifically, the outer side of the surround motor 14 is provided with a waterproof cover 21 that is detachably connected to the rotating base 6. Furthermore, the waterproof cover 21 can be detachably connected to the rotating base 6 by bolts. The waterproof cover 21 can prevent liquid overflowing during polishing from entering the surround motor 14, thereby protecting the surround motor 14.
