Cast steel parts are parts made from molten steel through a casting process. They have properties similar to those of cast iron, but usually have better strength. Cast steel parts have strong design flexibility and can be made into parts of various complex shapes and sizes. At the same time, cast steel parts have strong overall structural strength and good isotropy, which can improve the reliability of engineering. Polishing of cast steel parts is an important part of the casting surface treatment technology, aiming to further improve the gloss, corrosion resistance, wear resistance and anti-pollution performance of the casting surface.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0025] Embodiment:
[0026] Please refer to Figures 1-4 , this embodiment provides a surface polishing device for cast steel parts, including a base 1. At one end of the top of the base 1, two hydraulic telescopic columns 14 are installed. The top of the hydraulic telescopic column 14 is fixedly connected with a support frame 4. On the top of the support frame 4, an angle measuring plate 42 with angle scale lines is installed. An angle adjustment mechanism 5 is installed on the support frame 4. A motor 51 is installed on the angle adjustment mechanism 5. The top of the motor 51 is connected with a support column 53. One end of the support column 53 is rotatably connected to the support frame 4. An angle pointer 56 that rotates with the rotation point of the support column 53 is installed on the support column 53. The angle pointer 56 can point to the scale line of the angle measuring plate 42 when the support column 53 rotates to measure the rotation angle of the support column 53. An electric push rod 57 that can stretch the support column 53 to rotate is installed on one side surface of the support column 53. When this surface polishing device for cast steel parts is in use, the electric push rod 57 is used to stretch the support column 53 to rotate. During the rotation of the support column 53, the angle pointer 56 can synchronously point to the scale line of the angle measuring plate 42 to represent the rotation angle of the support column 53. Therefore, according to the operation method, the motor 51 can be adjusted to the required inclination angle according to the grinding needs of the cast steel part. Then, the hydraulic telescopic column 14 is used to drive the entire angle adjustment mechanism 5 to move downward to the top of the cast steel part. At this time, the cast steel part can be ground and polished according to the adjusted angle, which is very convenient. There is no need for manual holding of the cast steel part to continuously adjust the inclination angle on the grinding equipment to achieve grinding at different angles, thereby effectively improving the grinding and polishing efficiency of the cast steel part and having a certain operation safety guarantee.
[0027] In this embodiment, as Figure 1 andFigure 2 As shown, a feeding mechanism 2 is installed inside the groove 11. A turntable 21 is installed on the feeding mechanism 2. The turntable 21 is located inside the groove 11 and its top is flush with the top edge of the groove 11. The bottom center of the turntable 21 is fixedly connected to the top of the connecting shaft 12. Therefore, when the driving motor drives the connecting shaft 12 to rotate, the turntable 21 can rotate inside the groove 11.
[0028] In this embodiment, as Figure 1 and Figure 3 shown, a slide rod 22 is fixedly connected to the top center of the turntable 21. External threads are provided on the outer surface of a partial length of the top of the slide rod 22. A collar 23 is slidably sleeved on the outer ring surface of the slide rod 22. Support rods 24 are rotatably connected at equal intervals on the outer ring surface of the collar 23. One end of each support rod 24 is rotatably connected to a pressing block 25. A cast steel workpiece 3 is installed at the outer edge of the top of the turntable 21. The length of the support rod 24 is greater than the radius dimension of the cast steel workpiece 3. Therefore, when the pressing blocks 25 on the three support rods 24 continuously change the angle, they can continuously apply a pressing force to the inner wall of the cast steel workpiece 3.
[0029] In this embodiment, as Figure 1 and Figure 3 shown, a manual nut 26 is threadedly connected to the external threads on the outer surface of the slide rod 22. The bottom of the manual nut 26 is in contact with the top of the collar 23. When the manual nut 26 rotates clockwise, it can squeeze the collar 23 to move downward. Therefore, when the manual nut 26 is rotated manually, the support rods 24 on the collar 23 can be squeezed downward at the same time, thereby fixing the cast steel workpiece 3.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4 shown, an angle measuring plate 42 is installed on the edge of one end of the top of the support frame 4. A rotating groove 41 is provided at one end of the top of the support frame 4. One end of the support column 53 extends into the inside of the rotating groove 41. Rotating blocks 54 are symmetrically installed on both side surfaces of the top of the support column 53. The two rotating blocks 54 are rotatably connected to the inner side surfaces of both sides of the rotating groove 41. The center of the outer side surface of one rotating block 54 is connected to a round rod 55. One end of the round rod 55 penetrates through the rotating groove 41 and extends to the outer side surface of the angle measuring plate 42 and is connected to an angle pointer 56. Therefore, the angle pointer 56 is located on the outer side surface of the angle measuring plate 42 and can clearly point to the angle scale line.
[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, a grinding disc 52 is connected to the bottom output shaft of the motor 51. One end of the electric push rod 57 is rotatably connected to the inner side surface of the support frame 4. When the electric push rod 57 is perpendicular to the support column 53, the angle pointer 56 points to the 90° scale line on the angle measuring plate 42. Therefore, when the electric push rod 57 extends or retracts, the inclination angle of the grinding disc 52 can be changed, and the inclination angle can be indicated by the angle pointer 56, so as to facilitate the adjustment of the inclination angle of the grinding disc 52.
[0032] Working principle: When the surface polishing device for cast steel parts is in use, first place the cast steel workpiece 3 on the turntable 21, and then fit the three pressing blocks 25 with the inner wall of the cast steel workpiece 3. At this time, rotate the manual nut 26 clockwise to drive the collar 23 to move downward. At this time, when the angle of the three support rods 24 continuously becomes smaller, the pressing blocks 25 on the three support rods 24 can continuously apply a pressing force to the inner wall of the cast steel workpiece 3 to fix the cast steel workpiece 3. Then, according to the required grinding angle of the cast steel workpiece 3, use the electric push rod 57 to stretch the support column 53 to rotate. During the rotation of the support column 53, the angle pointer 56 can synchronously point to the scale line of the angle measuring plate 42 to indicate the rotation angle of the support column 53. Then, use the hydraulic telescopic column 14 to drive the angle adjustment mechanism 5 to move downward as a whole to the top of the cast steel part. At this time, the cast steel part can be ground and polished by the grinding disc 52 according to the adjusted angle, which is very convenient. There is no need for manual holding of the cast steel part to continuously adjust the inclination angle on the grinding equipment to achieve grinding at different angles, thus effectively improving the grinding and polishing efficiency of the cast steel part, and at the same time having a certain operation safety guarantee.
[0033] All technical features in this embodiment can be freely combined according to actual needs.
[0034] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
