[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figures 1 to 6 A polishing device for metal casting production includes a table 1, on which a polishing device 21 is provided, and the polishing device 21 is used to perform polishing activities on the casting.

[0030] A turning frame 2 is rotatably mounted inside the table top 1, and a clamping device 3 is provided on the turning frame 2;

[0031] There are two clamping devices 3, which are located on both sides of the flip frame 2. The two clamping devices 3 are started synchronously to achieve the clamping activity of the casting, ensuring that it will not shake during polishing and affect the polishing effect.

[0032] The rotation of the flip frame 2 can cause the casting clamped thereon to rotate synchronously, thereby realizing the flipping activity of the casting, eliminating the need for manual adjustment, and making the polishing activity more continuous and more efficient.

[0033] A fixing frame 5 is fixedly installed at the bottom of the table top 1, and a supporting grid plate 4 is fixedly installed inside the fixing frame 5. The supporting grid plate 4 can support the casting and provide a larger contact area, making the casting more stable during the processing and reducing the possibility of shaking and vibration. The casting is placed on the plane of the supporting grid plate 4, and the center of gravity is lower, which helps to improve the overall stability and reduces the risk of accidental falling of the casting.

[0034] It is worth noting that the distance between the flip frame 2 and the support grid plate 4 needs to be controlled so that the casting before and after flipping can smoothly contact the support grid plate 4 so that the support grid plate 4 can support it.

[0035] Furthermore, the design of the grid allows the debris and dust generated by polishing to fall smoothly through the supporting grid plate 4, making it convenient to collect them later.

[0036] One end of the supporting grid plate 4 is exposed from the fixing frame 5 and a pulling plate 6 is fixedly installed;

[0037] By pulling the handle on the plate 6, the pulling plate 6 can be moved, which can then drive the supporting grid plate 4 to move, thereby exposing the rotation path of the flip frame 2, so that the flip frame 2 can rotate smoothly. During the rotation of the flip frame 2, the debris on the casting can fall smoothly, which is convenient for later collection.

[0038] A driving device corresponding to the turning frame 2 is provided on the table 1 .

[0039] The driving device includes a driven gear 11 and a cylinder 13. The driven gear 11 is fixedly connected to the rotating shaft of the flip frame 2. The cylinder 13 is arranged at the bottom of the table 1, and the output end of the cylinder 13 is fixedly installed with an active rack 12 adapted to the driven gear 11.

[0040] The driven gear 11 is in meshing relationship with the driving rack 12 .

[0041] When the cylinder 13 is started, the active rack 12 can be moved. Since the driven gear 11 is in meshing relationship with the active rack 12, the movement of the active rack 12 can rotate the flip frame 2, thereby realizing the flipping of the casting.

[0042] A mounting block 14 is fixedly mounted inside the fixing frame 5 , and a cleaning brush 15 is fixedly mounted on a side of the mounting block 14 facing away from the table top 1 . The cleaning brush 15 can directly contact the supporting grid plate 4 .

[0043] When the support grid plate 4 is moved by pulling the plate 6, the support grid plate 4 can move relative to the cleaning brush 15, and then the cleaning brush 15 can shake off the debris and dust on the support grid plate 4 to ensure its cleanliness and facilitate use.

[0044] A slag collecting chamber 7 is fixedly installed at the bottom of the fixed frame 5, and a slag collecting frame 8 is movably installed inside the slag collecting chamber 7;

[0045] Debris and dust will fall directly into the slag collecting chamber 7 and gather inside the slag collecting frame 8, which can ensure the cleanliness of the table 1 and the flip frame 2. There is no need for frequent manual cleaning. When the slag collecting frame 8 is full, you only need to take out the slag collecting frame 8 and dump it to clean it, which is more convenient to use.

[0046] A servo motor 9 is provided on the table 1, and a mounting plate 10 is fixedly installed on the shaft output end of the servo motor 9. A stepper motor 16 is provided on the mounting plate 10, and a threaded rod 17 is fixedly installed on the shaft output end of the stepper motor 16. A nut pair 18 is threadedly connected to the threaded rod 17, and a telescopic rod 19 is fixedly installed on the nut pair 18. A mounting frame 20 is fixedly installed on the end of the telescopic rod 19 facing away from the nut pair 18, and a polishing device 21 is located inside the mounting frame 20.

[0047] Through the design of the servo motor 9, mounting plate 10, stepper motor 16 and threaded rod 17, the polishing device 21 has a fan-shaped polishing area, and the telescopic rod 19 allows the polishing device 21 to be adjusted on the Z axis, which can well cover castings of different sizes and heights and is easy to use.

[0048] The working process of the present invention: in the initial state, the supporting grid plate 4 is located directly below the flip frame 2, which can smoothly undertake the supporting activity of the casting. By placing the casting on the supporting grid plate 4, and then the two clamping devices 3 are started synchronously, the clamping activity of the casting can be realized to ensure that it will not shake during polishing, affecting the polishing effect.

[0049] It is worth noting that the distance between the flip frame 2 and the support grid plate 4 needs to be controlled so that the casting before and after flipping can smoothly contact the support grid plate 4 so that the support grid plate 4 can support it.

[0050] Then the polishing device 21 is started and the position is changed through the corresponding device to complete the polishing activity of the front side.

[0051] By pulling the handle on the plate 6, the pulling plate 6 can be moved, which can drive the supporting grid plate 4 to move, thereby exposing the rotation path of the flip frame 2. At the same time, the supporting grid plate 4 can move relative to the cleaning brush 15, and the cleaning brush 15 can shake off the debris and dust on the supporting grid plate 4.

[0052] Then the cylinder 13 is started to move the active rack 12. Since the driven gear 11 and the active rack 12 are in meshing relationship, the movement of the active rack 12 can rotate the flip frame 2, thereby realizing the flipping of the casting. During the rotation of the flip frame 2, the debris on the casting can fall smoothly, which is convenient for later collection.

[0053] Afterwards, the supporting grid plate 4 is returned to its original position and the back side can be polished.

[0054] Debris and dust will fall directly into the slag collecting chamber 7 and gather inside the slag collecting frame 8, which can ensure the cleanliness of the table 1 and the flip frame 2. There is no need for frequent manual cleaning. When needed, just take out the slag collecting frame 8 and dump it to clean it, which is more convenient to use.

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
