Abstract

Detailed implementation manners

[0024] The following combines the attached Figures 1-9 drawings and further illustrates the technical solution of the present invention through specific implementation manners.

[0025] The present invention provides an automated surface treatment system for castings, including a sand pool 130. A bottom sealing seat 135 is fixedly sealed at the bottom of the sand pool 130. A rotating disk 134 is rotatably installed on the bottom sealing seat 135. A plurality of rotating paddles 133 are fixedly arranged in a circular array on the rotating disk 134. A partition plate 132 is fixedly installed on the inner wall of the sand pool 130 through a partition plate support 131. The lower surface of the partition plate 132 is slidably engaged with all the rotating paddles 133. An opening is provided in the middle of the partition plate 132. A gap is provided between the circumference of the partition plate 132 and the inner wall of the sand pool 130 for driving the polishing sand inside the sand pool 130 to circulate. Among them, the rotating disk 134 is driven to rotate by a driving motor 137. A dust-proof support shell 136 is fixedly installed on the lower surface of the bottom sealing seat 135. An outer ring gear cover 138 is rotatably installed inside the dust-proof support shell 136. The outer ring gear cover 138 is fixed to the rotating disk 134 through a rotating shaft. A planetary gear support disk 142 is rotatably installed inside the outer ring gear cover 138. A planetary gear 140 meshing with the outer ring gear cover 138 is rotatably installed on the planetary gear support disk 142. A central gear 141 meshing with the planetary gear 140 is rotatably arranged at the axis of the outer ring gear cover 138. Among them, the central gear 141 is fixed to the output shaft of the driving motor 137 fixed on the dust-proof support shell 136. A rotating bearing is provided between the planetary gear support disk 142 and the outer ring gear cover 138 to reduce the frictional resistance between the two. Among them, an electromagnet 139 is arranged at the position between the outer ring gear cover 138 and the bottom sealing seat 135 inside the dust-proof support shell 136. The electromagnet 139 is fixed to the dust-proof support shell 136 or the bottom sealing seat 135. The electromagnet 139 is rotatably engaged with the outer ring gear cover 138. The planetary gear support disk 142 and the electromagnet 139 are magnetically engaged. The sand pool 130 is fixed on an intermediate support partition 101. Two symmetrically arranged lifting electric cylinders 103 are fixedly installed on the intermediate support partition 101. An adjusting support plate 104 is fixed on the telescopic rods of the two lifting electric cylinders 103. A sealing cover plate 105 is fixed on the adjusting support plate 104. Two parallel guide slide rods 106 are fixedly installed on the sealing cover plate 105. The top ends of the two guide slide rods 106 are fixed with a top cross beam 107.

[0026] A wire reel 113 is rotatably mounted on the top cross beam 107. A wire rope 114 is wound around the wire reel 113. A pulling motor bracket 108 is also fixed on the top cross beam 107. 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. The spline shaft 115 is fixedly matched with the wire reel 113. A rotation limiting disc 110 is sleeved on the spline shaft 115 in a spline sliding manner. A stationary limiting disc 112 is fixed at a position on the top cross beam 107 coaxial with the rotation limiting disc 110. A toothed shape capable of being mutually engaged is provided between the stationary limiting disc 112 and the rotation limiting disc 110. An elastic component 111 sleeved on the spline shaft 115 is rotatably mounted between the stationary limiting disc 112 and the rotation limiting disc 110 or between the rotation limiting disc 110 and the pulling motor bracket 108. An electromagnetic coil magnetically matched with the rotation limiting disc 110 is embedded in the pulling motor bracket 108 or the top cross beam 107. A pull plate frame 117 is also slidably mounted on the two guiding slide rods 106. A plurality of spline sleeve shafts 125 are rotatably mounted on the pull plate frame 117. A swing gear 123 is slidably mounted on the circumferential surface of each spline sleeve shaft 125 in a spline manner. A fastening cover plate 118 is fixed in the middle of the upper surface of the sealing cover plate 105. All the swing gears 123 are rotatably arranged between the fastening cover plate 118 and the sealing cover plate 105. A swing gear disc 122 meshing with all the swing gears 123 is also rotatably mounted at the center position between the fastening cover plate 118 and the sealing cover plate 105.

[0027] A swing arm rod 121 is also fixed on the swing gear disk 122. 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 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 part between the swing arm rod 121 and the adjusting electric cylinder 119 is in sliding fit with the arc-shaped slide rail 120, which is used to drive the swing gear disk 122 to rotate. A clamping pull rod 126 is slidably installed in the middle of each spline sleeve shaft 125. The bottom end of the clamping pull rod 126 extends below the bottom end of the spline sleeve shaft 125. The bottom ends of the spline sleeve shaft 125 and the clamping pull rod 126 are respectively fixed with a first clamping plate 127 and a second clamping plate 128. A clamping electric cylinder 124 is fixed at the top end of the spline sleeve shaft 125. The end of the telescopic rod of the clamping electric cylinder 124 is fixed to the clamping pull 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 pull plate frame 117. A tension spring 116 is wound around each guide slide rod 106. The two ends of the tension spring 116 are respectively fixed to the pull plate frame 117 and the buckle cover plate 118. A plurality of guide plates 129 arranged in a circular array are fixed on the lower surface of the sealing cover plate 105. The first clamping plate 127 and the second clamping plate 128 are arranged at the middle position between two adjacent guide plates 129. The middle support partition plate 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 contract. At this time, the telescopic rod of the clamping electric cylinder 124 drives the second clamping plate 128 to move towards 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 the first clamping plate 127 and the second clamping plate 128, multiple castings can be clamped simultaneously, and the surfaces of multiple castings can be polished simultaneously. It should be noted that the position of the spline sleeve shaft 125 on the sealing cover plate 105 can slide longitudinally, specifically adjusted by the pulling motor 109.

[0029] The telescopic rod of 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. On the premise that the relative positions of the spline sleeve shaft 125 and the sealing cover plate 105 remain unchanged, the first clamping plate 127 and the second clamping plate 128 can be controlled by the lifting electric cylinder 103 to sink into the polishing sand inside the sand pool 130. Then, the driving motor 137 is started, and the output shaft of the driving motor 137 drives the central gear 141 to rotate. The central gear 141 drives the planetary gear 140 to rotate on its own axis. When the planetary gear 140 cannot revolve, it will drive the outer gear cover 138 to rotate. The rotation of the outer gear cover 138 will drive the rotating disk 134 to rotate, and the rotation of the rotating disk 134 will drive the rotating dial 133 to rotate. The planetary gear 140 is installed on the planetary gear support disk 142. Therefore, the rotation of the planetary gear support disk 142 is the revolution of the planetary gear 140, and the rotation of the planetary gear support disk 142 is restricted by the magnetic force of the electromagnet 139. When the planetary gear support disk 142 is completely attracted by the magnetic force of the electromagnet 139, all the power of the central gear 141 is transmitted to the outer gear cover 138 (ignoring friction). On the contrary, if the electromagnet 139 does not completely attract the planetary gear support disk 142, part of the power will be transmitted to the revolution of the planetary gear support disk 142 at this time, thus reducing the rotation speed of the outer gear cover 138, and then resulting in a reduction in the rotation speed of the rotating dial 133. Therefore, the transmission ratio from the driving motor 137 to the rotating dial 133 can be adjusted by adjusting the magnetic force of the electromagnet 139 (a distance is set between the electromagnet 139 and the driving motor 137 to reduce the influence between the electromagnet 139 and the driving motor 137).

[0030] The rotation of the rotary dial 133 drives the grinding sand to rotate. The rotating grinding sand rotates towards the inner wall direction of the sand pool 130 under the action of centrifugal force. Since the rotation of the rotary dial 133 causes the grinding sand in the middle to flow outward, the grinding sand in other positions will flow towards the middle of the rotary dial 133. The grinding sand that moves to the inner wall position of the sand pool 130 will flow upward under the action of pressure, flow through the gap between the partition plate 132 and the sand pool 130 to the upper part of the partition plate 132, and then enter the middle of the rotary dial 133 through the opening in the middle of the partition 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 flowing grinding sand, and the flowing grinding sand will polish the surface of the casting, making the surface of the casting smoother. By controlling the telescopic movement of the telescopic rod of the adjusting electric cylinder 119, the swing angle of the swing arm rod 121 can be controlled. The swing of the swing arm rod 121 drives the swing of the swing gear disk 122. The swing of the swing gear disk 122 drives the swing of all the swing gears 123. The swing gears 123 drive the swing of the spline sleeve shaft 125. 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 flowing direction of the grinding sand, realizing the grinding of different positions of the casting (if necessary, after grinding one side, the casting needs to be removed and then the other side is ground to achieve all-round grinding and polishing).

[0031] When high-speed grinding is required, it is necessary to accelerate the flow rate of the grinding sand. Therefore, the grinding sand inside the sand pool 130 is likely to leak out. Thus, the sealing cover plate 105 is needed to hold 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 reel 113 to rotate through the spline shaft 115, and then winds the wire rope 114 around the wire reel 113. At this time, the wire rope 114 will pull the pull plate frame 117 to move upward. The pull plate frame 117 drives all the spline sleeve shafts 125 to move upward, so that all the spline sleeve shafts 125 located below the sealing cover plate 105 move to the upper part. In this way, the sealing cover plate 105 can be buckled on the sand pool 130. When the pulling motor 109 stops moving, it is necessary to make the stationary limit disk 112 always in contact and engagement with the rotating limit disk 110. Since the stationary limit disk 112 is fixed to the top cross beam 107 and the rotating limit disk 110 slides with the spline shaft 115 in a spline manner, the spline shaft 115 and the rotating limit disk 110 rotate synchronously. When the rotating limit disk 110 engages with the stationary limit disk 112, the spline shaft 115 cannot rotate, and the wire reel 113 cannot rotate either. At this time, the position of the pull plate frame 117 on the guiding slide rod 106 remains unchanged (it is pulled back by the tension spring 116 during reset). Therefore, the rotating limit disk 110 can be attracted by the electromagnetic coil embedded in the pulling motor bracket 108 or the top cross beam 107. If the elastic component 111 is arranged between the stationary limit disk 112 and the rotating limit disk 110, the electromagnetic coil needs to be arranged in the top cross beam 107. When the electromagnetic coil is energized, it will attract the rotating limit disk 110, thereby compressing the elastic component 111 and making the rotating limit disk 110 contact and engage with the stationary limit disk 112. In this way, it is necessary to keep the electromagnetic coil energized all the time, or the elastic component 111 is arranged between the rotating limit disk 110 and the pulling motor bracket 108. Only when the electromagnetic coil is energized, the rotating limit disk 110 will move away from the stationary limit disk 112. By default, the rotating limit disk 110 is always in an engaged relationship with the stationary limit disk 112, which needs to be adaptively selected according to the actual situation. The purpose of the guiding plate 129 is to guide the directional flow of the grinding sand.
