Description

Technical Field

[0001] The present invention relates to the technical field of ceramic plate surface leveling, and specifically to a surface leveling device for radiation-proof ceramic plates. Background Technique

[0002] Due to its excellent radiation shielding performance and durability, radiation-proof ceramic plates are widely used in medical, nuclear industry, military and other fields. Its surface flatness directly affects the sealing performance, aesthetics and service performance of the plate. In medical equipment, arc-shaped radiation-proof ceramic plates are used, and these arc-shaped radiation-proof ceramic plates usually require manual polishing and grinding of the inner wall to meet the high standards of the industry for the quality of the plates.

[0003] In the polishing and grinding of arc-shaped radiation-proof ceramic plates, especially in the fine processing link for the arc-shaped inner wall, traditionally, workers rely on hand-held polishing machines to operate to ensure that the arc-shaped inner wall can obtain a uniform and comprehensive polishing effect. However, due to the special shape of the arc-shaped inner wall, it is difficult for workers to ensure that each part can be polished to the same degree during grinding. This not only leads to low work efficiency, but also may affect the flatness of the arc-shaped inner wall due to uneven force control and improper angle adjustment. The decrease in flatness not only affects the appearance aesthetics of the product, but may also have an adverse impact on its radiation-proof performance, thereby reducing the overall quality and use safety of the product.

An adjusting column 313 is fixedly installed on the bottom surface of one end of the moving bar 312.

[0036] In this embodiment: When the provided piston plate 310 moves on the inner wall of the fixed shell 301, the fixed shell 301 sucks cooling water from the fixed pipe 302 and discharges cooling water from the connecting pipe 304.

[0037] Specifically, as Figures 1-8 shown, a rotating bar 316 is fixedly installed on the outer wall of one side cylinder 211.

[0038] In this embodiment: By providing the arc plate 314 and the corrugated groove 315, when the arc plate 314 rotates by a certain angle, the corrugated groove 315 drives the adjusting column 313, the moving strip 312 and the piston plate 310 to reciprocate.

[0039] Specifically, this solution is as follows: Place the arc-shaped radiation-proof ceramic plate on the fixing component 102 and fix it.

Turn on the motor 209 to drive the connecting shaft 207 and the polishing roller 208 to rotate to polish the inner wall of the arc-shaped radiation-proof ceramic plate. Turn on the second electric push rod 218, so that the second electric push rod 218 drives the moving frame 214 to reciprocate. The moving frame 214 drives the cylinder 211 to move. Under the limitation of the arc-shaped groove 212, the cylinder 211 rotates on the inner wall of the arc-shaped groove 212. The cylinder 211 drives the fixing strip 210 and the first fixing sleeve 205 to rotate by a certain angle. The first fixing sleeve 205 drives the rotating shaft 204 to rotate by a certain angle. The first fixing sleeve 205 drives the mounting plate 206 and the polishing roller 208 to rotate by a certain angle and perform an arc-shaped reciprocating swing, so that the distance between the polishing roller 208 and the inner wall of the arc-shaped radiation-proof ceramic plate is always kept the same, thereby improving the flatness of the inner wall of the arc-shaped radiation-proof ceramic plate. At the same time, when the cylinder 211 rotates, it drives the rotating strip 316 and the fixing column 317 to rotate, drives the arc plate 314 to rotate. When the corrugated groove 315 on the arc plate 314 rotates, it drives the adjusting column 313 and the moving strip 312 to reciprocate. The moving strip 312 drives the piston plate 310 to reciprocate. The piston plate 310 sucks cooling water from the tank body 303 through the fixed pipe 302, and sprays the cooling water from the nozzle 309 to the polishing roller 208 and the radiation-proof ceramic plate through the connecting pipe 304, the hose 305 and the water spraying pipe 308 to cool the polishing area of the radiation-proof ceramic plate, prevent the polishing area of the radiation-proof ceramic plate from overheating and cracking and damage, thereby improving the polishing quality of the radiation-proof ceramic plate.
