[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The positioning-based sealing valve body grinding equipment disclosed in this invention is mainly used in scenarios where traditional valve body grinding fixtures are mostly single-point or planar hard supports, which cannot fit the contour of the sealing valve body, resulting in the grinding point being misaligned and uneven grinding on the sides.

The outer side of the rotating balls 1209 is in contact with the outer side of the valve body. Positioning sensors 1217 are provided on both sides of the arc-shaped support plate 1210. Two side grinding components 17 are arranged above the positioning sensor 1217. Each side grinding component 17 includes a main grinding component 1705, a plurality of secondary grinding blades 1709 are arranged around the main grinding component 1705, and a plurality of nozzles 1714 are arranged around the secondary grinding blades 1709.

[0021] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In a preferred embodiment, the support positioning component 12 further includes: The drive motor 1201 is located inside the base 4. The power output shaft of the drive motor 1201 is connected to the rotating plate 1202 through a coupling. A circular groove is provided on the outer side of the base 4, and the outer side of the rotating plate 1202 is movably connected to the inside of the circular groove. Two fixing rods 1204 are fixedly connected at their bottom ends to the top ends of the rotating plate 1202. Two movable gears 1205, the inner sides of which are rotatably connected to the outer sides of two fixed rods 1204 respectively; Two arc-shaped gear holders 1203 are fixedly connected to the inner side of the bottom of the grinding device 1 at their bottom ends. The arc-shaped gear holders 1203 and the movable gear 1205 mesh with each other through tooth grooves. Two connecting rods 1206, the top ends of which are respectively fixedly connected to the top ends of two movable gears 1205; Two fixing brackets 1207 are fixedly connected at their bottom ends to the top ends of two connecting rods 1206 respectively.

[0022] In this invention, the support positioning component 12 further includes: Two movable seats 1208 are fixedly connected to the top of two fixed frames 1207 at their bottom ends, and the top ends of the movable seats 1208 are respectively set at the bottom ends of two arc-shaped support plates 1210. Two return springs 1211 are fixedly connected to the opposite sides of the two arc-shaped support plates 1210 respectively. The ends of the return springs 1211 away from the arc-shaped support plates 1210 are fixedly connected to the sides of the two fixed brackets 1207 away from the drive motor 1201 respectively. Two symmetrical arc-shaped slide plates 1212 are fixedly connected to the two sides of the arc-shaped support plate 1210 on opposite sides.

[0023] In this invention, the support positioning component 12 further includes: Two symmetrical sliders 1213, each symmetrical slider 1213 is slidably connected on the opposite side to the opposite side of each symmetrical arc-shaped slide plate 1212; Two side brackets 1214 are provided on both sides of the bottom of the sliding member 1213 located on the same side; Two electric telescopic rods 1215 are fixedly connected to opposite sides of two side-mounted frames 1214, and the telescopic ends of the electric telescopic rods 1215 are fixedly connected to opposite sides of two positioning sensors 1217.

Each arc-shaped frame 1216 has a circular hole, and the outside of the positioning sensor 1217 is slidably connected to the inside of the circular hole.

[0024] Specifically, after the valve body is placed in position, the outer curved surface of the valve body will come into contact with the rotating ball 1209 on the surface of the arc-shaped support plate 1210. As the valve body is in place, the arc-shaped support plate 1210 is pushed outward by the spherical surface of the valve body and begins to expand outward. During the outward movement of the arc-shaped support plate 1210, it will compress the return spring 1211. The return spring 1211 is compressed and deformed. The movable seat 1208 moves outward along with the arc-shaped support plate 1210. During the displacement process, the arc-shaped support plate 1210... The sliding parts 1213 on both sides are moved synchronously along the trajectory of the arc-shaped slide plate 1212. When the sliding parts 1213 move, they drive the side frame 1214 to move together. The angle between the two side frames 1214 is gradually reduced. After the valve body is roughly in place, the electric telescopic rod 1215 is activated. The telescopic end of the electric telescopic rod 1215 extends outward and pushes the positioning sensor 1217 to slide forward along the round hole opened inside the arc-shaped frame 1216 until the detection surface of the positioning sensor 1217 is attached to the outer wall surface of the sealing valve body. In specific application scenarios, it can form a multi-point wrapping support for the sealing valve body, conforming to the irregular contour of the valve body, so that the valve body is not easy to shake or shift during the grinding operation, ensuring the stability of the grinding position. It should be noted that the support is evenly distributed, dispersing the grinding impact and vibration generated when the grinding wheel contacts the valve body, reducing the problem of scratches and bumps on the valve body surface caused by vibration, and protecting the sealing surface of the valve body from damage.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10 In a preferred embodiment, the side grinding assembly 17 further includes: Movable component 1701 is slidably connected to the outside of linear track 16; Side plate 1702 is fixedly connected to the side of movable part 1701 away from linear track 16; The automatic rotating seat 1703 has a circular hole on the side plate 1702, and the outer side of the automatic rotating seat 1703 is set inside the circular hole; Rotating plate 1704 is fixedly connected to the side of automatic rotating seat 1703 near base 4, and main grinding part 1705 is fixedly connected to the side of rotating plate 1704 away from automatic rotating seat 1703.

[0026] In this invention, the side grinding assembly 17 further includes: Circular plate 1706 is fixedly connected to the rotating plate 1704 on the side near the automatic rotating seat 1703; Multiple curved rods 1707 are fixedly connected to the side of the circular plate 1706 near the automatic rotating seat 1703. Multiple snap-fit ​​pieces 1708 are fixedly connected to one end of each bent rod 1707 away from the circular plate 1706. The inner side of each snap-fit ​​piece 1708 is located on the outer side of the auxiliary grinding blade 1709.

[0027] In this invention, the side grinding assembly 17 further includes: Multiple coolant storage tanks 1710 are provided on the outside of the curved rod 1707. Multiple fasteners 1712 are fixedly connected to the outer side of the bent rod 1707 on their inner sides. The fasteners 1712 are located between the secondary grinding tool 1709 and the coolant storage tank 1710. Multiple surrounding water pumps 1711, the outer side of each surrounding water pump 1711 is fixedly connected to the inner side of the fixing member 1712, and the suction end of each surrounding water pump 1711 is respectively located on the side of the coolant storage tank 1710 near the auxiliary grinding blade 1709.

[0028] Specifically, the automatic rotating seat 1703 is started, and the automatic rotating seat 1703 begins to rotate at a constant speed, driving the rotating plate 1704 and the main grinding part 1705 to rotate together around the outside of the valve body, continuously grinding around the outer surface of the valve body. During the rotational grinding process of the main grinding component 1705, the circular plate 1706, the bent rod 1707, and the snap-fit ​​component 1708 follow the main grinding component 1705 in a circular motion, driving multiple sets of auxiliary grinding blades 1709 to contact the outer surface of the spherical sealing valve body in sequence. The auxiliary grinding blades 1709 at different positions perform fine grinding on different curved areas of the valve body sidewall in sequence, achieving large-scale, dead-angle-free processing of the outer surface of the valve body. When the secondary grinding blade 1709 is performing fine grinding, the coolant stored in the coolant storage tank 1710 is pumped by the water pump 1711 and transported through the connecting pipe 1713 to the nozzle 1714 and sprayed out, forming a continuous liquid cooling and flushing effect in the grinding contact area, and promptly washing away the debris and residue generated during grinding. In specific application scenarios, it can automatically grind the side edges of the sealing valve body to remove burrs, flash and casting residue protrusions generated on the side of the valve body, so that the side end face of the valve body is flat and smooth. It should be noted that the grinding position can be adjusted according to the side height and width of the sealing valve body of different specifications, and it is suitable for grinding and processing of various valve bodies, making the equipment highly versatile.

[0029] Reference Figures 1-4 In a preferred embodiment, it further includes: Control button 2 is located in front of the grinding device 1; Two cabinet doors 3 are located in front of the polishing device 1, and the cabinet doors 3 are located above the control button 2; Two connecting devices 7, with their two ends fixed to the inside sides of the grinding device 1 respectively; Two columns 8, with their ends fixedly connected to the inner sides of two connecting devices 7 respectively; The connecting frame 9 has its inner ends fixedly connected to the outer sides of the two columns 8; Rotate handle 10, which is located above the connecting bracket 9; The threaded rod 11 has its top end fixedly connected to the bottom end of the rotating handle 10. The connecting frame 9 has a threaded hole, and the outer side of the threaded rod 11 is threadedly connected to the inside of the threaded hole. Connector 15, one end of which is fixedly connected to the outer side of threaded rod 11; The top of the upper grinding component 13 is fixedly connected to the bottom of the end of the connector 15 away from the threaded rod 11, and the upper grinding component 13 is positioned directly above the placement block 6. Cooling valve 18 is mounted on the rear plate 14 and is located below the rotary automatic component 21. Two cooling pipes 19 are respectively installed at both ends of the cooling valve 18, and the upper grinding component 13 is installed between the two cooling pipes 19. Two coolant spray heads 20 are respectively located at the ends of the two cooling pipes 19 away from the cooling valve 18.

[0030] Working principle: When grinding the sealing valve body, the operator opens the cabinet door 3, places the spherical sealing valve body to be processed on the placement block 6, and then rotates the handle 10. The threaded rod 11 moves downward along with the handle 10, driving the connecting piece 15 and the upper grinding piece 13 to descend until the grinding working surface of the upper grinding piece 13 is in contact with the top outer surface of the sealing valve body. After the valve body is placed in position, the outer curved surface of the valve body will come into contact with the rotating ball 1209 on the surface of the arc-shaped support plate 1210. As the valve body is in place, the arc-shaped support plate 1210 is pushed outward by the ball surface of the valve body and begins to expand outward. During the outward movement of the arc-shaped support plate 1210, it will compress the return spring 1211. The return spring 1211 is compressed and deformed. The movable seat 1208 moves outward along with the arc-shaped support plate 1210. During the displacement process, the arc-shaped support plate 1210... The sliding parts 1213 on both sides move along the trajectory of the arc-shaped slide plate 1212. When the sliding parts 1213 move, they drive the side frame 1214 to move together. The angle between the two side frames 1214 gradually decreases. After the valve body is roughly in place, the electric telescopic rod 1215 is activated. The telescopic end of the electric telescopic rod 1215 extends outward, pushing the positioning sensor 1217 to slide forward along the round hole opened inside the arc-shaped frame 1216 until the detection surface of the positioning sensor 1217 is in contact with the outer wall surface of the sealing valve body. After the valve body is positioned, the two sets of side grinding components 17 can be started. The movable part 1701 in the side grinding component 17 moves towards the valve body along the guide trajectory of the straight track 16. When the side grinding component 17 moves to the appropriate processing position on both sides of the valve body, it stops moving. At this time, the main grinding part 1705 approaches the outer wall of the sealing valve body and contacts its surface. The upper grinding component 13, which has been lowered into position, continues to press against the top of the valve body to perform grinding operations on the top surface of the sealing valve body. At the same time, the automatic rotating seat 1703 is started. The automatic rotating seat 1703 begins to rotate at a constant speed, driving the rotating plate 1704 and the main grinding component 1705 to rotate around the outside of the valve body and continuously grind along the outer surface of the valve body. During the rotational grinding process of the main grinding component 1705, the circular plate 1706, the bent rod 1707, and the snap-fit ​​component 1708 follow the main grinding component 1705 in a circular motion, driving multiple sets of auxiliary grinding blades 1709 to contact the outer surface of the spherical sealing valve body in sequence. The auxiliary grinding blades 1709 at different positions perform fine grinding on different curved areas of the valve body sidewall in sequence, achieving large-scale, dead-angle-free processing of the outer surface of the valve body. During the continuous grinding process, the cooling valve 18 is opened, and the coolant is transported through the cooling pipe 19 to the coolant spray head 20 and sprayed outward onto the surface of the grinding area of ​​the valve body. When the secondary grinding blade 1709 performs fine grinding, the coolant stored in the coolant storage tank 1710 is pumped by the water pump 1711 and transported through the connecting pipe 1713 to the spray head 1714 and sprayed out, forming a continuous liquid cooling and flushing effect in the grinding contact area, and promptly washing away the debris and residue generated during grinding.
