Example

[0034] like Figure 1-Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a mounting plate 31 is fixedly provided on the top surface of the base plate 1, a lifting plate 32 is slidingly provided on the front surface of the mounting plate 31, a walking device 34 is fixedly provided on the bottom surface of the lifting plate 32, and the bottom surface of the walking block of the walking device 34 is fixedly connected to the top surface of the grinder 35. A through groove is provided on the back surface of the mounting plate 31, and a lifting block 38 is slidingly provided on the inner wall of the through groove, and the front surface of the lifting block 38 is fixedly connected to the back surface of the lifting plate 32. A control board 37 is fixedly provided on the back surface of the lifting block 38, and an electric telescopic rod 36 is fixedly provided on the back surface of the mounting plate 31, and the top surface of the output end of the electric telescopic rod 36 is fixedly connected to the bottom surface of the control board 37. A wedge-shaped groove is provided on the front surface of the mounting plate 31, and a wedge block 33 is slidingly provided on the inner wall of the wedge groove, and the front surface of the wedge block 33 is fixedly connected to the back surface of the lifting plate 32.

[0035] In this embodiment, the grinding mechanism 3 controls the up and down movement of the lifting plate 32 through the electric telescopic rod 36, driving the grinder 35 to move synchronously to adapt to castings of different sizes. The motor 24 is turned on to rotate the casting and the walking device 34 controls the left and right reciprocating movement of the grinder 35 to achieve the overall grinding and deburring of the casting. The wedge groove on the front of the mounting plate 31 cooperates with the wedge block 33 and the through groove on the back cooperates with the lifting block 38, which ensures the stability and accuracy of the movement of the lifting plate 32 and improves the grinding accuracy and efficiency of the burr removal of aluminum alloy castings.

[0036] When in use, first place the aluminum alloy casting that needs to be polished inside the three-jaw chuck 23, and then fix the left end of the aluminum alloy casting by locking the three-jaw chuck 23. After the fixation is completed, manually control the sliding plate 21 to move so that the right end of the aluminum alloy casting moves between the two clamping blocks 28. The two springs 26 and the two dampers 25 can make the two clamping plates 27 and the two clamping blocks 28 approach each other, so that the right end of the aluminum alloy casting can be clamped. In the process of the two clamping plates 27 approaching each other, the first tooth plate 213 can be obtained by the two sliding blocks 214. The first tooth plate 213 and the second tooth plate 215 move in a direction opposite to each other, and the gear 219 rotates when the first tooth plate 213 and the second tooth plate 215 move. After the first tooth plate 213 and the second tooth plate 215 stop moving, the gear 219 also stops rotating. After stopping rotating, the extrusion bolt 217 is rotated so that the left side of the extrusion bolt 217 contacts the inner wall of the extrusion groove, thereby fixing the gear 219. After fixing the gear 219, the first tooth plate 213 and the second tooth plate 215 can be fixed, so that the two clamping plates 27 and the two clamping blocks 28 can be fixed for a second time.

[0037] After the fixation is completed, the lifting plate 32 can be moved up and down by controlling the extension and retraction of the output end of the electric telescopic rod 36. During the up and down movement of the lifting plate 32, the grinder 35 can be driven to move synchronously. After the bottom surface of the grinder 35 contacts the aluminum alloy casting, the electric telescopic rod 36 is closed, and the grinder 35 and the motor 24 are turned on. After the grinder 35 is turned on, the aluminum alloy casting can be polished, and after the motor 24 is turned on, the aluminum alloy casting can be rotated, and then the entire casting can be polished. By turning on the walking device 34, the grinder 35 can be controlled to move back and forth in the left and right directions, so that it can perform overall polishing and deburring of the aluminum alloy casting.

[0038] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
