[0021] Example: Reference Figure 1-4 The shown casting polishing device comprises a base plate 1, U-shaped plates 2 are fixedly installed on both sides of the base plate 1, clamping cylinders 3 are fixedly installed on both sides of the U-shaped plate 2, the output ends of the two clamping cylinders 3 pass through the sides of the U-shaped plate 2 and are fixedly installed with rotating motors 4, and the output shafts of the rotating motors 4 are fixedly installed with clamping blocks 10; two rectangular sliding frames 22 are fixedly installed on the top of the base plate 1, square sliding columns 19 are slidably installed in the two rectangular sliding frames 22, and fixed plates 16 are fixedly installed on the tops of the two square sliding columns 19, and a supporting base plate 11 is installed on the top of the fixed plate 16 through an adjusting mechanism, extrusion holes are opened on the sides of the two rectangular sliding frames 22 away from each other, and extrusion columns 21 are fixedly installed on the sides of the two square sliding columns 19 away from each other, a grinding mechanism is fixedly installed on the side of the base plate 1, two extrusion rods 23 are installed on the grinding mechanism, and the two extrusion rods 23 are respectively in contact with the sides of the two extrusion columns 21, and a spraying mechanism is installed on the top of the base plate 1.

[0022] By means of the above structure: the casting can be placed through the support base plate 11 so that the center of the casting and the center of the clamping blocks 10 on both sides are on the same horizontal line, and the two clamping blocks 10 can be used to fix the casting by starting the clamping cylinder 3, and then the extrusion rod 23 can be moved by starting the grinding mechanism, thereby squeezing the extrusion column 21 to move it downward, so that the support base plate 11 can move downward to avoid it, and the height of the support base plate 11 can be adjusted by the adjustment mechanism, so as to facilitate the alignment of castings of different sizes.

[0023] like Figure 1 As shown, the spraying mechanism includes a water tank 6 fixedly mounted on the top of the U-shaped plate 2, a water pump 7 fixedly mounted on one side of the water tank 6, a water inlet end of the water pump 7 is connected to the water tank 6, a water outlet end of the water pump 7 passes through the top of the U-shaped plate 2 and is fixedly mounted with a hose 9, a water outlet cylinder 14 is mounted at the bottom end of the hose 9, a plurality of evenly arranged liquid outlet holes are provided on the inner wall of the bottom side of the water outlet cylinder 14, a connecting cylinder 5 is fixedly mounted on the side of the U-shaped plate 2, an output end of the connecting cylinder 5 passes through the side of the U-shaped plate 2 and is fixedly mounted with an arc plate 13, and the arc plate 13 is fixedly connected to the end of the water outlet cylinder 14. Start the water pump 7, and then the polishing liquid will be pumped out from the water tank 6, enter the water outlet cylinder 14 through the hose 9, and flow out through the multiple liquid outlet holes on the water outlet cylinder 14, and spray to the part where the casting contacts the polishing sheet 12, which plays a role in cooling and improving the polishing effect. By starting the connecting cylinder 5, the water outlet cylinder 14 moves back and forth, thereby causing the multiple liquid outlet holes to move back and forth, thereby evenly spraying the polishing liquid.

[0024] like Figure 3-Figure 4 As shown, the adjustment mechanism includes a threaded hole opened at the top of the fixing plate 16, a stud 18 is installed in the threaded hole, and the top of the stud 18 is rotatably installed on the bottom of the supporting base plate 11; two slide bars 17 are fixedly installed at the bottom of the supporting base plate 11, and two guide holes are opened at the top of the fixing plate 16, and the bottom ends of the two slide bars 17 respectively penetrate the two guide holes; a turntable is fixedly installed at the bottom end of the stud 18. When the turntable is turned, the stud 18 rotates accordingly, and the fixing plate 16 matched with it moves upward, so that the supporting base plate 11 drives the casting to move upward, so that the center of the casting and the center of the clamping blocks 10 on both sides are located on the same horizontal line.

[0025] like Figure 4 As shown, two telescopic rods 24 are fixedly installed at the bottom of the fixed plate 16, and the bottom ends of the two telescopic rods 24 are fixedly installed on the top of the bottom plate 1. The two telescopic rods 24 are sleeved with springs 20, and the two ends of the two springs 20 are respectively fixedly installed on the sides of the fixed plate 16 and the bottom plate 1 that are close to each other. The arrangement of the springs 20 facilitates the resetting of the extrusion column 21.

[0026] like Figure 1 , Figure 2 , Figure 3As shown, the grinding mechanism includes a rectangular plate 15 mounted on the side of the bottom plate 1, a telescopic cylinder 25 is fixedly mounted on the side of the rectangular plate 15, the output end of the telescopic cylinder 25 penetrates the side of the rectangular plate 15 and is fixedly mounted with a polishing sheet 12, a horizontal rod is mounted on one end of two extrusion rods 23, and the ends of the two horizontal rods away from the extrusion rods 23 are fixedly connected to the output end of the telescopic cylinder 25 through an L-shaped rod 8. When the telescopic cylinder 25 is started, as the output shaft of the telescopic cylinder 25 is extended, the polishing sheet 12 is constantly approaching the casting, thereby grinding.

[0027] Working principle: When in use, first place the casting on the supporting base plate 11, turn the turntable, the stud 18 rotates accordingly, and the fixed plate 16 matched therewith moves upward, so that the supporting base plate 11 drives the casting to move upward, so that the center of the casting and the center of the clamping blocks 10 on both sides are located on the same horizontal line, and then the clamping cylinder 3 is started, and the output ends of the clamping cylinders 3 on both sides approach each other to drive the two clamping blocks 10 to approach each other. After the two clamping blocks 10 tightly clamp the casting, the telescopic cylinder 25 is started, and as the output shaft of the telescopic cylinder 25 is extended, the polishing sheet 12 continuously approaches the casting, and the L-shaped rod 8 fixed on the output shaft of the telescopic cylinder 25 moves in the direction close to the clamping block 10;

[0028] At the same time, the horizontal rod fixedly connected to the L-shaped rod 8 drives the extrusion rod 23 to move in the direction close to the clamping block 10, and squeezes the extrusion column 21, so that the extrusion column 21 fixed on the square sliding column 19 moves downward along the slide groove in the rectangular sliding frame 22, and the telescopic rod 24 is deformed, and drives the square sliding column 19, the fixed plate 16, and the supporting bottom plate 11 to move downward, so that the supporting bottom plate 11 no longer contacts the casting, ensuring smooth rotation of the casting. At this time, the polishing sheet 12 continues to move, and the extrusion column 21 contacts the bottom of the horizontal rod. The horizontal rod will not squeeze the extrusion column 21 until the polishing sheet 12 stops moving after contacting the casting. By setting the horizontal rod, the polishing sheet 12 moves a short distance, so that the supporting bottom plate 11 can move downward to avoid it, and the rotating motor 4 is started. The rotating motors 4 on both sides start to rotate and drive the clamping block 10 to rotate, thereby realizing the rotation of the casting, thereby grinding;

[0029] At the same time, start the water pump 7, and then the polishing liquid will be pumped out from the water tank 6, enter the water outlet cylinder 14 through the hose 9, and flow out through the multiple liquid outlet holes on the water outlet cylinder 14, and spray to the part where the casting contacts the polishing sheet 12, which plays a role in cooling and improving the polishing effect. By starting the connecting cylinder 5, the water outlet cylinder 14 moves back and forth, thereby causing the multiple liquid outlet holes to move back and forth, thereby evenly spraying the polishing liquid.

[0030] After polishing is completed, the telescopic cylinder 25 is started to shrink its output end, thereby moving the polishing sheet 12 away from the casting. As the output shaft of the telescopic cylinder 25 shortens, the L-shaped rod 8 fixed on the output shaft of the telescopic cylinder 25 moves in the direction away from the clamping block 10. At the same time, the horizontal rod fixedly connected to the L-shaped rod 8 drives the extrusion rod 23 to move in the direction away from the clamping block 10, and under the action of the spring 20 and the telescopic rod 24, the supporting base plate 11 continuously approaches the casting until it contacts the casting to achieve reset. At this time, the output ends of the clamping cylinders 3 on both sides are controlled to move in the direction away from the casting, so that the casting is out of the clamping state. At this point, the entire polishing process is completed.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
