Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of polishing equipment, in particular to a valve casting surface polishing equipment. BACKGROUND

[0002] Valve casting is a valve component manufactured by casting process, usually made of cast iron, cast steel and other materials, used for adjusting flow, preventing backflow, isolating system, etc., widely used in petrochemical, power, metallurgy, water treatment and other fields. Valve casting surface polishing refers to the process of fine processing the surface of valve casting by physical or chemical methods to reduce its surface roughness, improve smoothness, and improve appearance and performance. Valve casting surface polishing is generally polished by a vibrating grinder. The vibrating grinder generates high-frequency vibration through a vibrating motor or a vibration exciter, so that the workpiece in the grinding barrel and the grinding medium (such as steel balls, ceramic balls, abrasives, etc.) produce relative motion.

[0003] At present, when the surface of the valve casting is polished by the vibrating grinder, the grinding balls are poured into the inside of the grinding barrel, the vibrating grinder is started, and the grinding balls roll in the inside of the grinding barrel. The valve casting is placed in the grinding barrel, and the surface of the valve is polished with the rolling of the grinding balls. After polishing, the valve casting is manually found in the inside of the grinding balls, the valve in the inside of the grinding balls is separated out by the magnetic conveying belt or is separated out by installing a ladder on the grinding barrel. The speed of the two is relatively slow, and the manual searching is easy to cause hand injury due to the rough and uneven surface of the grinding balls. The magnetic conveying belt is easy to separate the grinding balls and cause the grinding balls to splash, wasting the grinding material. The valve is separated out by the ladder installed on the grinding barrel, and a part of the grinding balls is also separated out. When the valve is completely separated out, the separated grinding balls need to be poured into the inside of the grinding barrel again, and the separation is not thorough enough. Moreover, after the polishing of the valve in the inside of the grinding barrel is completed, only the valve is taken out, and the grinding balls are still in the inside of the grinding barrel. A lot of powder is generated during polishing, but the bottom of the grinding barrel is sealed, and a screening mechanism for the grinding balls and the powder is not installed, causing the polishing of the valve to be not comprehensive enough and affecting the polishing efficiency. Moreover, the grinding balls need to be scooped out when the powder in the inside of the grinding barrel is cleaned, and the speed is slow. SUMMARY

[0035] Specifically, referring to Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 and Figure 10As shown, the collecting barrel 501 is provided with an ash discharge mechanism 7, the ash discharge mechanism 7 comprises an ash discharge port 704, a plurality of ash discharge ports 704 are equidistantly arranged at the side edge of the collecting barrel 501, a plurality of slide rods 702 are equidistantly and slidably connected to the side wall of the collecting barrel 501, the bottom of the plurality of slide rods 702 is fixedly connected with a limiting ring 701, a plurality of springs 703 are equidistantly arranged between the limiting ring 701 and the collecting barrel 501, and the limiting ring 701 is located outside the ash discharge port 704; the bracket 601 and the bottom of the collecting barrel 501 are provided with a power assisting mechanism 8, the power assisting mechanism 8 comprises a mounting bracket 801, the side wall of the bracket 601 is provided with the mounting bracket 801, a driving piece six 802 is mounted on the mounting bracket 801, the output end of the driving piece six 802 is key-connected with a gear 803, a toothed ring 804 is mounted on the bottom of the collecting barrel 501, and the gear 803 is engaged with the toothed ring 804; after the grinding ball falls on the filter screen 604, the powder in the grinding ball is filtered to the bottom of the collecting cavity 503, due to the inclined arrangement of the inner bottom of the collecting barrel 501, the limiting ring 701 can be pulled upward, the spring 703 is contracted, the ash discharge port 704 is opened, the collected powder is cleaned out of the ash discharge port 704, the limiting ring 701 is released to reset the spring 703, then the limiting ring 701 seals the ash discharge port 704 again, and dust overflow is avoided, when the grinding ball is poured into the inside of the collecting cavity 503, the driving piece six 802 can be started to drive the gear 803 to rotate, the driving piece six 802 is a motor, and further, the gear 803 cooperates with the toothed ring 804 to drive the collecting barrel 501 to rotate, the screening speed of the powder in the grinding ball by the screen 502 is improved, the separation of the ground powder is more thorough, and the grinding ball can quickly return to the grinding cavity 403 for polishing.

[0036] In use, this invention firstly involves polishing the surface of the valve casting, ensuring that the lifting plate 402 is in contact with the inner bottom of the grinding barrel 1, adding grinding balls into the grinding chamber 403, and then placing the valve inside the grinding chamber 403. The first drive component 304 is activated, driving the two eccentric blocks 305 to rotate. The first drive component 304 is a vibration motor, and its rotation frequency can be controlled to change the amplitude. After the first drive component 304 is activated, it causes the grinding balls inside the grinding barrel 1 to tumble, thus polishing the valve. Once the valve inside the grinding barrel 1 is polished, the three fourth drive components 603 located at the bottom of the rotating frame 602 are activated. The fourth drive component 603 is a cylinder. After the telescopic ends of the three fourth drive components 603 extend, the filter screen 604 is lowered onto the collection barrel 501. Then, the second drive component 404 located on the sliding shell 401 is activated. The second drive component 404 is also a cylinder. After the extension end of the second actuator 404 extends, it lifts the sliding shell 401, further raising the lifting plate 402 inside the grinding chamber 403. At this time, the grinding balls and valves are pushed out together. Due to the inclined setting of the lifting plate 402, when the bottom of the lifting plate 402 exceeds the top of the grinding barrel 1, the grinding balls and valves are quickly discharged from the grinding chamber 403. After the grinding balls and valves are discharged, they fall onto the filter screen 604. The filter screen 604 separates the grinding balls. At this time, the fifth actuator 606 starts to drive the rotating frame 602 to rotate. The fifth actuator 606 is a motor, so that the grinding balls fall to the bottom of the filter screen 604, and the valves are left on the filter screen 604. This completes the quick removal and separation of the valves, avoiding the problem of scratches from manual removal and the waste of grinding balls caused by magnetic separation ladders. Then, the fourth actuator 603 is retracted, so that the filter screen 604 rises, preventing the filter screen 604 from affecting subsequent operations. The valves on the filter screen 604 can then be removed.

[0037] Then, after the filter screen 604 sorts the grinding balls and valves, the valves remain on the filter screen 604, and the grinding balls fall from the bottom of the filter screen 604. The fallen grinding balls are collected by the collection chamber 503. Since the collection barrel 501 is equipped with a screen 502, the grinding balls can be collected while the powder generated during polishing can be filtered, preventing the powder inside the grinding balls from returning to the grinding barrel 1 and affecting the polishing of the next batch of valves. After filtration, multiple drive components 504 located inside the collection barrel 501 are activated to lift the screen 502. The drive component 504 is a cylinder. A bellows cover 506 is provided between the drive component 504 and the screen 502 to protect the telescopic end of the drive component 504. Since the screen 502 is tilted, when the screen 502 exceeds the top of the grinding barrel 1, the grinding balls can quickly roll into the grinding chamber 403 to quickly fill the grinding media. When the grinding balls on the screen 502 fill the grinding chamber 403, the drive component 504 resets.

[0038] Finally, after the grinding ball falls on the filter screen 604, the powder inside the grinding ball is filtered to the bottom of the collection cavity 503. Due to the inclined arrangement of the bottom of the collection barrel 501, the limiting ring 701 can be pulled upward, the spring 703 is contracted, the ash outlet 704 is opened, the collected powder is cleaned out of the ash outlet 704, the limiting ring 701 is loosened to reset the spring 703, and then the limiting ring 701 seals the ash outlet 704 again to prevent dust overflow. When the grinding ball is poured into the inside of the collection cavity 503, the driving member six 802 can be started to drive the gear 803 to rotate. The driving member six 802 is a motor, and the gear 803 cooperates with the gear ring 804 to drive the collection barrel 501 to rotate, improve the screening speed of the powder in the grinding ball by the screen 502, and make the ground powder separate more thoroughly, so that the grinding ball can quickly return to the grinding cavity 403 for polishing.
