[0019] Furthermore, a method for using a surface treatment device for ferrous metal casting, the surface treatment device for ferrous metal casting, the method includes the following steps:

[0020] S1: Rotating adjustment: First, connect the wool wheel to the connection disk, and then rotate the threaded rod to drive the placement plate to slide, adjust the distance between multiple placement plates, and then place the workpiece to be polished inside the multiple placement plates;

[0021] S2: Position adjustment: Then start the servo motor at the bottom of the hydraulic rod and the hydraulic rod. When the hydraulic rod works, it will drive the support frame to rise. Then when the servo motor works, it will drive the hydraulic rod to rotate so that the support frame rotates above the connection ring;

[0022] S3: Rotating and polishing: Then control the hydraulic rod to make the support frame slide downward. When the support frame slides downward, the notch at the bottom of the rotating ring will be engaged with the toothed ring, and at the same time, the connection disk will drive the wool wheel to contact the surface of the workpiece. Then start the motor to drive the connection disk to rotate. When the connection disk rotates, it will polish the workpiece surface through the wool wheel.

[0023] The present invention has the following beneficial effects:

[0024] 1. In the present invention, when the notch at the bottom of the rotating ring contacts the top of the gear ring, then when the motor is started, the motor will drive the short plate and the gear disc to rotate, and the gear disc will drive the transmission rod to rotate when rotating, and the transmission rod will drive the connecting disc to rotate through the spring rod when rotating, and the connecting disc will drive the wool wheel to grind the workpiece when rotating. At the same time, when the motor drives the short plate to rotate, the rotation of the short plate will drive the rotating frame and the transmission rod to swing back and forth, and when the rotating frame is shaking, it will drive the rotating ring and the square plate to swing synchronously through the short rod, and when the square plate is shaking, it will drive the connecting disc and the wool wheel to slide back and forth on the surface of the workpiece through the spring rod to polish, and at the same time, when the rotating ring is shaking, the rotating ring The shaking of the gear ring will cause the gear ring to rotate and squeeze up and down. When the middle plate is squeezed by the up and down rotation of the rotating ring, it will push the semicircular frame through the threaded rod to drive the workpiece to rotate back and forth. When the semicircular frame drives the workpiece to shake back and forth, different positions on the workpiece surface can be alternately exposed to the wool wheel, which can increase the uniformity of contact between the wool wheel and the workpiece surface. At the same time, the back and forth sliding and rotation of the wool wheel on the workpiece surface can slide back and forth on the surface of the workpiece. Combined with the shaking of the workpiece driven by the semicircular frame, the wool wheel can cover a wider area of ​​the workpiece surface, which can reduce the occurrence of polishing dead angles during polishing, save labor, and help improve the uniformity of the polishing process and improve polishing efficiency.

[0025] 2. In the present invention, when the connecting plate rotates at the bottom of the spring rod as the workpiece sways on the surface of the workpiece, the connecting plate will form a certain tilt angle with the spring rod as the workpiece rotates. When the connecting plate tilts at the bottom of the spring rod as the workpiece sways, the inner ring on the spring rod will pull the two ends of the semicircular plate through the T-shaped rod and the two long plates connected thereto to make them close together. When the semicircular plates are close together, they will first push the pushing plate to slide inside the sliding frame through the auxiliary plate and the movable plate. Then, as the two ends of the semicircular plates continue to move closer together, the auxiliary plate will push the sliding frame to slide in the direction of the wool wheel through the movable plate. At the same time, when the two pushing plates slide inside the sliding frame, the pushing plates The sliding of the hollow plate will squeeze one end of the hollow plate through the rotating block, causing it to bulge outward. When the two hollow plates are deformed and squeeze the outer surface of the wool wheel as the sliding frame slides, the wool wheel can be locally deformed after being squeezed by the hollow plates during the polishing process as the workpiece shakes. When the wool wheel is squeezed on the tilted surface of the workpiece, the squeezing of the side wall of the wool wheel by the hollow plate can make different parts of the wool wheel more evenly stressed, reducing the excessive pressure concentrated in the local area of ​​the wool wheel due to excessive local squeezing of the workpiece, thereby making the friction between various parts of the wool wheel and the workpiece more even during the polishing process, reducing the local excessive wear when the workpiece shakes, and improving the polishing quality.

[0026] 3. In the present invention, when the two ends of the semi-circular plate approach and push the sliding frame to slide, the approach of the semi-circular plate causes the obtuse rod to slide inside the rectangular groove. At this time, the auxiliary spring on the obtuse rod drives the obtuse rod to slide inside the second rectangular groove behind the sliding frame. When the obtuse rod slides, it drives the right-angle block to squeeze the protruding part of the elastic plate. After being squeezed, the elastic plate pushes the spring shaft to slide outward on the surface of the second limiting frame. When the spring shaft slides, it drives the roller to extend outside the hollow plate and contact the outer wall of the wool wheel, which can convert the sliding friction between the wool wheel and the hollow plate into rolling friction and provide more uniform support and rolling, avoiding the situation of excessive local friction when the wool wheel and the hollow plate are in sliding friction, making the force on the wool wheel more uniform in the entire circumferential direction, further reducing the problem of local damage caused by uneven friction, and helping to maintain the integrity of the wool wheel surface and the consistency of the polishing effect.

[0027] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] When the notch at the bottom of the rotating ring 303 comes into contact with the top of the toothed ring 206, and then when the motor 304 is started, the operation of the motor 304 will drive the short plate 305 and the toothed disc to rotate. When the toothed disc rotates, it will drive the transmission rod 501 to rotate. When the transmission rod 501 rotates, it will drive the connecting disc 503 to rotate through the spring rod 502. When the connecting disc 503 rotates, it will drive the wool wheel to polish the workpiece. At the same time, when the motor 304 drives the short plate 305 to rotate, the rotation of the short plate 305 will drive the rotating frame 403 and the transmission rod 501 to swing back and forth. When the rotating frame 403 swings, it will drive the rotating ring 303 and the square plate 402 to swing synchronously through the short rod 401. When the square plate 402 swings, it will drive the connecting disc 503 and the wool wheel to slide back and forth on the surface of the workpiece through the spring rod 502 for polishing. At the same time, when the rotating ring 303 swings, the swing of the rotating ring 303 will perform undulating rotational extrusion on the toothed ring 206. When the middle plate 205 is squeezed by the undulating rotation of the rotating ring 303, it will push the semi-circular frame 201 through the threaded rod 202 to drive the workpiece to rotate back and forth. When the semi-circular frame 201 drives the workpiece to swing back and forth, different positions on the surface of the workpiece can be alternately exposed under the wool wheel, which can increase the uniformity of the contact between the wool wheel and the surface of the workpiece. At the same time, the back-and-forth sliding and rotation of the wool wheel on the surface of the workpiece can slide back and forth on the surface of the workpiece. Combining the swing of the workpiece driven by the semi-circular frame 201 can make the area covered by the wool wheel on the surface of the workpiece wider. Furthermore, it can reduce the occurrence of polishing dead corners during polishing, save labor, and at the same time help improve the uniformity during the polishing process and improve the polishing efficiency.

[0062] When the connecting plate 503 rotates at the bottom of the spring rod 502 along with the undulation of the workpiece on the surface of the workpiece, a certain inclination angle will be formed between the connecting plate 503 and the spring rod 502 as the connecting plate 503 rotates along with the undulation of the workpiece. When the connecting plate 503 inclines at the bottom of the spring rod 502 along with the swaying of the workpiece, the inner ring 704 on the spring rod 502 will pull both ends of the semi-circular plate 604 to make them approach each other through the T-shaped rod 703 and the two long plates 702 connected thereto. When the semi-circular plate 604 approaches, it will first push the push plate 803 to slide inside the sliding frame 804 through the auxiliary plate 801 and the movable plate. Subsequently, with the continuous approach of both ends of the semi-circular plate 604, the auxiliary plate 801 will push the sliding frame 804 to slide towards the direction of the wool wheel through the movable plate. At the same time, when the two push plates 803 slide inside the sliding frame 804, the sliding of the push plate 803 will squeeze one end of the hollow plate 904 through the rotating block to cause it to generate a deformation of bulging outwards. When the two hollow plates 904 squeeze the outer surface of the wool wheel as they deform along with the sliding of the sliding frame 804, the wool wheel can undergo local deformation after being squeezed by the hollow plate 904 during the process of polishing along with the swaying of the workpiece. When the wool wheel is inclined and squeezed on the surface of the workpiece, the extrusion of the hollow plate 904 on the side wall of the wool wheel can make the forces on different parts of the wool wheel more uniform, reducing the situation that the pressure is too large and concentrated in the local area of the wool wheel due to excessive local extrusion of the workpiece. Thus, the friction between each part of the wool wheel and the workpiece during the polishing process is more uniform, reducing the situation of local excessive wear when the workpiece sways and improving the polishing quality.

[0063] When both ends of the semi-circular plate 604 approach and push the sliding frame 804 to slide, the approach of the semi-circular plate 604 will cause the obtuse-angle rod 805 to slide inside the rectangular groove 605. At this time, the auxiliary spring on the obtuse-angle rod 805 will drive the obtuse-angle rod 805 to slide inside the second rectangular groove 802 behind the sliding frame 804. When the obtuse-angle rod 805 slides, it will drive the right-angle block to squeeze the protruding part on the elastic plate 901. After being squeezed, the elastic plate 901 will push the spring shaft 902 to slide outwards on the surface of the limiting frame two 903. When the spring shaft 902 slides, it will drive the roller to extend to the outside of the hollow plate 904 and contact the outer wall of the wool wheel, which can convert the sliding friction between the wool wheel and the hollow plate 904 into rolling friction and provide more uniform support and rolling, avoiding the situation that the local friction force is too large when the wool wheel and the hollow plate 904 are in sliding friction, making the forces on the wool wheel in the entire circumferential direction more uniform, further reducing the problem of local damage caused by uneven friction, and helping to maintain the integrity of the surface of the wool wheel and the consistency of the polishing effect.
