The top openings of the three bottom plates 115 all point to the rotation center, and the piston blocks 106 are installed in the three bottom plates 115 in a sliding and sealing manner. The piston blocks 106 are elastically connected to the center of the reinforcing plate 111 through the return spring 110. A pull rod 107 is fixed to each piston block 106, and the pull rod 107 and the pressurized pipe 105 are in sliding and sealing cooperation. A counterweight block 108 is fixedly provided at one end of the pull rod 107 away from the piston block 106, and a lift wing 109 is fixed to the counterweight block 108.

[0026] The working principle of a high-temperature alloy part surface polishing system disclosed in the present invention is as follows: the high-temperature alloy part to be polished is placed in the clamping frame 136, and then the part is clamped and fixed in the clamping frame 136 by the telescopic rod 137. At this time, the clamping frame 136 and the part will rotate with the rotating pressure transmission shaft tube 133. Specifically, the drive motor 125 is started, and the output shaft of the drive motor 125 drives the intermediate transition shaft 129 to rotate through the third transmission belt 127, and the intermediate transition shaft 129 drives the rotating pressure transmission shaft tube 133 to rotate through the fourth transmission belt 128. Therefore, during the rotation process, the part will move relative to the sand in the sand storage barrel 131, so the sand will polish the surface of the part, and different surfaces can be polished by changing the clamping position on the clamping frame 136. When the rotating pressure transmission shaft tube 133 rotates, it will also drive the grinding sand driving impeller 134 to rotate. The grinding sand driving impeller 134 rotates and drives the grinding sand inside the grinding sand storage barrel 131 to enter the reflux collection chamber 132 through the sand discharge port 138, and then flow back into the grinding sand storage barrel 131 through multiple grinding sand reflux channels 130, realizing the circulation of grinding sand. At this time, the grinding sand also has displacement in the longitudinal direction of the part, so that the surfaces of the part in two directions can be polished at the same time, and there is no need to consider the contour shape of the part surface, and complex parts can be polished.

[0027] The output shaft of the driving motor 125 will also drive the central gear 121 to rotate. The rotation of the central gear 121 will drive the planetary gear 120 to rotate. The rotation of the planetary gear 120 will revolve under the restriction of the gear ring 119. The rotation of the gear ring 119 is controlled by the adjusting motor 123. The limiting adjusting gear 124 on the output shaft of the adjusting motor 123 will limit the rotation of the gear ring 119. The revolution of the planetary gear 120 will drive the planetary gear support disk 118 to rotate. The rotation of the planetary gear support disk 118 will drive the driving pulley 139 to rotate. The rotation of the driving pulley 139 will drive the input shaft of the planetary gearbox 113 to rotate through the second transmission belt 116. The output shaft of the planetary gearbox 113 will drive the rotating pressure pipe 104 to rotate through the first transmission belt 112. The rotation of the rotating pressure pipe 104 will drive all the pressurized pipes 105 to rotate. The rotation of the pressurized pipe 105 will drive the counterweight 108 and the lift wing 109 to rotate. Liquid is provided in the pool 102 to increase the medium density. The counterweight 108 rotates and moves outwards under the action of centrifugal force, and drives the piston 106 to squeeze the internal space of the pressure tube 105 through the pull rod 107, so that the internal pressure of the pressure tube 105 increases. Since the pressure tube 105, the rotating pressure pipe 104, and the rotating pressure transmission shaft tube 133 are connected, the internal pressure of the rotating pressure transmission shaft tube 133 increases, which leads to an increase in the internal pressure of the telescopic tube 135. At this time, the telescopic rod 137 will squeeze the parts under the action of pressure. In order to ensure the squeezing force, the lift wing 109 is set. The rotation of the lift wing 109 will generate lift relative to the internal liquid of the pool 102, so that the lift wing 109 will also move outwards. At this time, combined with the centrifugal force of the counterweight 108, the force of the piston 106 squeezing the inside of the pressure tube 105 can be further increased, thereby further increasing the pressure inside the pressure tube 105, and then increasing the squeezing force of the telescopic rod 137 on the parts. The size of the extrusion force of the telescopic rod 137 can be adjusted by the rotation speed of the pressure tube 105 and the rotating pressure tube 104, which is suitable for parts with different profile structures and materials. Specifically, by controlling the adjustment motor 123, the output shaft of the adjustment motor 123 will control the restriction of the gear ring 119 by limiting the adjustment gear 124, thereby controlling the transmission ratio of the power output from the central gear 121 to the planetary gear support disk 118. For example, when the gear ring 119 is in a completely free state, the rotation of the central gear 121 cannot drive the planetary gear support disk 118 to rotate. If the gear ring 119 is slightly resisted, the central gear 121 will transfer part of the power to the planetary gear support disk 118 and the other part to the gear ring 119. By analogy, by changing the power ratio of the two parts, the transmission ratio between the central gear 121 and the planetary gear support disk 118 can be adjusted, thereby changing the rotation speed of the pressure tube 105.
