A dustproof support shell 136 is fixed to the lower surface of the bottom sealing seat 135, and an outer ring gear cover 138 is rotatably installed inside the dustproof support shell 136. The outer ring gear cover 138 is fixed to the rotating disk 134 by a rotating shaft, and a planetary gear support disk 142 is rotatably installed inside the outer ring gear cover 138. Planetary gears 140 meshing with the outer ring gear cover 138 are rotatably installed on the planetary gear support disk 142. A central gear 141 meshing with the planetary gears 140 is rotatably provided at the axis center of the outer ring gear cover 138, wherein the central gear 141 is fixed to the output shaft of the driving motor 137 fixed on the dustproof support shell 136. A rotating bearing is arranged between the planetary gear support plate 142 and the outer ring gear cover 138 to reduce the friction resistance between the two. An electromagnet 139 is arranged inside the dustproof support shell 136 between the outer ring gear cover 138 and the bottom sealing seat 135. The electromagnet 139 is fixed to the dustproof support shell 136 or the bottom sealing seat 135. The electromagnet 139 is rotationally matched with the outer ring gear cover 138, and the planetary gear support plate 142 and the electromagnet 139 are magnetically matched. The sand pool 130 is fixed on the middle support partition 101. Two symmetrically arranged lifting electric cylinders 103 are also fixedly installed on the middle support partition 101. The two lifting electric cylinders 103 telescopic rods are fixed with an adjusting support plate 104. The adjusting support plate 104 is fixed with a sealing cover plate 105. Two parallel guide slide bars 106 are fixedly installed on the sealing cover plate 105. The top ends of the two guide slide bars 106 are fixed with a top crossbeam 107.

[0026] A wire drum 113 is rotatably mounted on the top crossbeam 107, and a wire rope 114 is wound around the wire drum 113. A pulling motor bracket 108 is also fixed on the top crossbeam 107, and a pulling motor 109 is fixed on the pulling motor bracket 108. A spline shaft 115 is fixed on the output shaft of the pulling motor 109, and the spline shaft 115 is fixedly matched with the wire drum 113, wherein a rotation limiting disk 110 is sleeved on the spline shaft 115 by a spline sliding manner, and the top crossbeam 107 is connected with the rotation limiting disk 110. A stationary limiting disk 112 is fixed at a coaxial position of the limiting disk 110, and teeth that can be engaged with each other are arranged between the stationary limiting disk 112 and the rotating limiting disk 110. An elastic component 111 mounted on the spline shaft 115 is rotatably installed between the stationary limiting disk 112 and the rotating limiting disk 110 or between the rotating limiting disk 110 and the pulling motor bracket 108. An electromagnetic coil that magnetically cooperates with the rotating limiting disk 110 is embedded in the pulling motor bracket 108 or the top cross beam 107. A pull plate frame 117 is also slidably installed on the two guide slide rods 106, and a plurality of spline sleeve shafts 125 are rotatably installed on the pull plate frame 117. A swing gear 123 is slidably installed on the circumferential surface of each spline sleeve shaft 125 in a spline manner. A buckle cover plate 118 is fixed to the middle part of the upper surface of the sealing cover plate 105, wherein all the swing gears 123 are rotatably arranged between the buckle cover plate 118 and the sealing cover plate 105, and a swing toothed disc 122 meshing with all the swing gears 123 is also rotatably installed at the center position of the circle between the buckle cover plate 118 and the sealing cover plate 105.

[0027] A swing arm rod 121 is also fixed on the swing gear plate 122, and the swing arm rod 121 is located above the buckle cover plate 118. An arc-shaped slide rail 120 is also fixed on the buckle cover plate 118. An adjusting electric cylinder 119 is also movably installed on the buckle cover plate 118. The end of the telescopic rod of the adjusting electric cylinder 119 is movably connected to the swing arm rod 121. The movable connection between the swing arm rod 121 and the adjusting electric cylinder 119 is slidably matched with the arc-shaped slide rail 120 to drive the swing gear plate 122 to rotate. A clamping rod 126 is slidably mounted in the middle of each spline sleeve shaft 125, the bottom end of the clamping rod 126 extends below the bottom end of the spline sleeve shaft 125, and the bottom ends of the spline sleeve shaft 125 and the clamping rod 126 are respectively fixed with a first clamping plate 127 and a second clamping plate 128, wherein a clamping electric cylinder 124 is fixed to the top end of the spline sleeve shaft 125, and the end of the telescopic rod of the clamping electric cylinder 124 is fixed to the clamping rod 126, which is used to adjust the distance between the first clamping plate 127 and the second clamping plate 128. One end of the wire rope 114 is fixed to the plate frame 117, and a tension spring 116 is arranged around each guide slide bar 106, and the two ends of the tension spring 116 are respectively fixed to the plate frame 117 and the buckle cover plate 118. A plurality of guide plates 129 arranged in a circular array are fixed to the lower surface of the sealing cover plate 105 , wherein the first clamping plate 127 and the second clamping plate 128 are arranged in the middle position between two adjacent guide plates 129 , and the middle supporting partition 101 is fixed inside the housing 102 .

[0028] Place the casting to be polished between the first clamping plate 127 and the second clamping plate 128, and then control the telescopic rod of the clamping electric cylinder 124 to retract. At this time, the telescopic rod of the clamping electric cylinder 124 drives the second clamping plate 128 to move toward the first clamping plate 127 through the clamping pull rod 126. At this time, the casting will be clamped between the first clamping plate 127 and the second clamping plate 128. Since there are multiple pairs of first clamping plates 127 and second clamping plates 128, multiple castings can be clamped at the same time, and the surfaces of multiple castings can be polished at the same time. It should be noted that the position of the spline sleeve shaft 125 on the sealing cover plate 105 can slide longitudinally, which is specifically adjusted by the pulling motor 109.

[0029] The telescopic rod controlling the lifting electric cylinder 103 can control the vertical displacement of the adjusting support plate 104, and the sealing cover plate 105 on the adjusting support plate 104 will move accordingly. Under the premise that the relative positions of the spline sleeve shaft 125 and the sealing cover plate 105 remain unchanged, the lifting electric cylinder 103 can be used to control the first clamping plate 127 and the second clamping plate 128 to sink into the grinding sand inside the sand pool 130, and then the driving motor 137 is started. The output shaft of the driving motor 137 drives the central gear 141 to rotate, and the central gear 141 drives the planetary gear 140 to rotate. When the planetary gear 140 cannot revolve, it will drive the outer ring gear cover 138 to rotate. The rotation of the outer ring gear cover 138 will drive the rotating disk 134 to rotate. The rotation of the rotating disk 134 will drive the rotating dial plate 133 to rotate. The planetary gear 140 is installed on the planetary gear support disk 142, so the planetary gear 140 The rotation of the support plate 142 is the revolution of the planetary gear 140, and the rotation of the planetary gear support plate 142 will be limited by the magnetic force of the electromagnet 139. When the planetary gear support plate 142 is completely attracted by the magnetic force of the electromagnet 139, the power of the center gear 141 is completely transmitted to the outer ring gear cover 138 (ignoring the friction force). On the contrary, if the electromagnet 139 does not completely attract the planetary gear support plate 142, part of the power will be transmitted to the revolution of the planetary gear support plate 142, thereby reducing the rotation speed of the outer ring gear cover 138, and then causing the rotation speed of the rotating dial plate 133 to decrease. Therefore, the transmission ratio from the drive motor 137 to the rotating dial plate 133 can be adjusted by adjusting the magnetic force of the electromagnet 139 (a distance is set between the electromagnet 139 and the drive motor 137 to reduce the influence of the electromagnet 139 and the drive motor 137).

[0030] The rotation of the rotating dial plate 133 will drive the grinding sand to rotate, and the grinding sand will rotate toward the inner wall of the sand pool 130 under the action of centrifugal force. Since the rotation of the rotating dial plate 133 will cause the grinding sand in the middle to flow outward, the grinding sand in other positions will flow toward the middle of the rotating dial plate 133, and the grinding sand moved to the inner wall of the sand pool 130 will flow upward under the action of pressure, flow to the top of the dividing plate 132 through the gap between the dividing plate 132 and the sand pool 130, and then enter the middle of the rotating dial plate 133 through the opening in the middle of the dividing plate 132. The casting installed between the first clamping plate 127 and the second clamping plate 128 will be located on the path of the grinding sand flow, and the flowing grinding sand will grind the surface of the casting, thereby making the surface of the casting smoother. By controlling the extension and retraction of the telescopic rod of the electric cylinder 119, the swing angle of the swing arm rod 121 can be controlled. The swing of the swing arm rod 121 will drive the swinging gear plate 122 to swing, and the swinging gear plate 122 will drive all the swinging gears 123 to swing, and the swinging gear 123 will drive the spline sleeve shaft 125 to swing. Therefore, the casting installed on the first clamping plate 127 and the second clamping plate 128 will swing, so that different positions of the casting face the flow direction of the grinding sand, thereby realizing the grinding of different positions of the casting (if necessary, after grinding one side, the casting needs to be removed and the other side needs to be polished to achieve all-round grinding and polishing).

[0031] When high-speed grinding is required, the flow rate of the grinding sand needs to be accelerated, so the grinding sand inside the sand pool 130 is easy to leak out. Therefore, the sealing cover 105 needs to buckle the grinding sand in the sand pool 130 to prevent the leakage of the grinding sand. At this time, it is necessary to control the pulling motor 109. The output shaft of the pulling motor 109 drives the wire drum 113 to rotate through the spline shaft 115, and then the wire rope 114 is wound around the wire drum 113. At this time, the wire rope 114 will pull the pull plate frame 117 to move upward, and the pull plate frame 117 drives all the spline sleeve shafts 125 to move upward, so that the spline sleeve shafts 125 located below the sealing cover plate 105 are all moved to the top, so that the sealing cover plate 105 can be buckled on the sand pool 130. When the pulling motor 109 stops moving, the stationary limiting disk 112 needs to be always in contact and engaged with the rotating limiting disk 110. Since the stationary limiting disk 112 is fixed to the top cross beam 107, the rotating limiting disk 110 and the spline shaft 115 slide through the spline, so the spline shaft 115 rotates synchronously with the rotating limiting disk 110. When the rotating limiting disk 110 is engaged with the stationary limiting disk 112, the spline shaft 115 cannot rotate, and the wire drum 113 cannot rotate either. At this time, the position of the pulling plate frame 117 on the guide slide rod 106 remains unchanged (it is pulled back by the tension spring 116 when resetting). Therefore, the electromagnetic coil embedded in the pulling motor bracket 108 or the top crossbeam 107 can attract the rotation limiting disk 110. If the elastic component 111 is set between the static limiting disk 112 and the rotation limiting disk 110, the electromagnetic coil needs to be set in the top crossbeam 107. When the electromagnetic coil is energized, it will attract the rotation limiting disk 110, thereby compressing the elastic component 111, so that the rotation limiting disk 110 and the static limiting disk 112 are in contact and meshed. In this way, the electromagnetic coil needs to be always energized, or the elastic component 111 is set between the rotation limiting disk 110 and the pulling motor bracket 108. Only when the electromagnetic coil is energized, the rotation limiting disk 110 will move away from the static limiting disk 112. In the default state, the rotation limiting disk 110 is always in meshing relationship with the static limiting disk 112. This needs to be adaptively selected according to the actual situation. The purpose of the guide plate 129 is to guide the directional flow of the grinding sand.
