[0012] Specifically, the telescopic outer rod 105 is provided with two first air grooves 208, and a first piston 209 is slidably connected in each first air groove 208.

The outer grinding rod 108 is provided with a second air groove 304, and a second piston 305 is slidably connected in the second air groove 304.

[0014] Working principle: Before using the device, the operator first places the raw material assembly 106 on the grinding base 101 and adjusts it to the center. Then, the operator controls the electric telescopic rod 102 to extend. As the electric telescopic rod 102 extends, it pushes the upper hanger 103 downward. At this time, the telescopic outer rod 105 contacts and is positioned at the bottom positioning hole 107 of the electric telescopic rod 102 through the inner ring of the raw material assembly 106. As the electric telescopic rod 102 continues to move downward, the telescopic inner rod 104 is pressed into the central sliding cavity 109 inside the telescopic outer rod 105. At this time, the gas in the central sliding cavity 109 enters the first gas groove 208 through the first gas guide cavity 303, and the gas passes through the central gas cavity 308. 09. The air guide pipe 401, air guide ring 402, and second air guide chamber 308 enter the second air groove 304. At this time, the air pressure in the first air groove 208 and the second air groove 304 increases. Under the action of air pressure, the first piston 209 is pushed to slide outward along the first air groove 208. At this time, the first piston 209 and the first fixing plate 301, which are fixedly connected to the first piston 209, move outward and abut against the inner wall of the raw material group 106. At the same time, under the action of air pressure, the second piston 305 slides outward along the second air groove 304. At this time, the second fixing plate 306 and the second grinding layer 307, which are fixedly connected to the second piston 305, move outward and abut against the outer wall of the raw material group 106. Simultaneously, the inner rod extends and retracts. The upper positioning ring 206 on the lower surface of the telescopic outer rod 104 contacts and locks with the lower positioning ring 207 on the upper surface of the telescopic outer rod 105. At this time, the telescopic outer rod 105 and the telescopic inner rod 104 are axially fixed. At this time, the operator starts the motor 200, which drives the drive gear 201 to rotate. The drive gear 201 drives the driven gear 202 to rotate, that is, the telescopic inner rod 104 rotates relative to the upper hanger 103. At the same time, a large gear 203 is fixedly connected to the telescopic inner rod 104. The large gear 203 drives the planetary gear 204 and the gear ring 205 to rotate. At this time, the gear ring 205 rotates in the opposite direction along the axis of the telescopic inner rod 104. Due to the first grinding layer 302 and the second grinding layer... Layer 307 maintains relative contact with the inner and outer walls of the raw material assembly 106. The inner and outer walls of the raw material assembly 106 are polished by rotating the telescopic inner rod 104 and the outer polishing rod 108. After polishing is completed, the motor is turned off and the electric telescopic rod 102 is controlled to retract. At this time, the gas in the second air groove 304 and the first air groove 208 flows back into the central sliding cavity 109. At this time, the first piston 209 and the second piston 305 are reset, that is, the first polishing layer 302 and the second polishing layer 307 are separated from the surface of the raw material assembly 106. As the electric telescopic rod 102 continues to retract, the upper hanger 103 moves upward. At this time, the polished raw material assembly 106 can be taken out. The device is then reset for the next use.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
