Description

Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to a surface polishing device for die-casting aluminum alloy. Background Art

[0002] After removing the trimmings from aluminum alloy die castings, further polishing is required to eliminate burrs, knife marks or surface stains. Since die castings are generally special-shaped parts, it is inconvenient to polish them with grinding wheels. Therefore, magnetic polishing machines are often used for polishing. The working principle of magnetic polishing machines is to drive the magnetic abrasive in the container barrel to produce relative movement with the workpiece surface through the rotating disk, so as to make the workpiece surface smooth.

[0003] When the magnetic polishing machine is running, only the magnetic abrasive moves in the container barrel, and the workpiece does not move. To reduce the polishing dead angle, the only way is to change the movement direction of the magnetic abrasive and extend the polishing time, which is not conducive to improving the polishing efficiency. Summary of the invention

[0004] In order to solve the problems mentioned in the background technology, the object of the present invention is to provide a surface polishing device for die-casting aluminum alloy.

[0005] In order to achieve the above object, the technical solution of the present invention is:

[0006] A die-cast aluminum alloy surface polishing device comprises a base, wherein the base is provided with a loading plate, an anti-overflow bucket is vertically overlapped on the loading plate, a container barrel is vertically rotatably installed in the anti-overflow bucket, a plurality of movable gears are mounted on the bottom plate of the anti-overflow bucket, a circular boss is coaxially arranged on the top of the movable gear, a plurality of circular holes matching the size of the boss are transparently arranged on the bottom plate of the container barrel, a plurality of the bosses are respectively assembled in a plurality of the circular holes, a fixed gear is fixedly connected to the bottom plate of the anti-overflow bucket, the fixed gear is coaxially arranged with the rotation axis of the container barrel, a plurality of the movable gears are all meshed with the fixed gear, a magnetic disk is rotatably installed on the base below the loading plate, and a first driving member and a second driving member for driving the container barrel and the magnetic disk to rotate are respectively arranged on the base.

[0007] By adopting the above scheme, the aluminum alloy die-casting and the magnetic abrasive are placed in the container barrel, and the magnetic disk and the container barrel are driven to rotate in opposite directions. The rotation of the container barrel can drive the aluminum alloy die-casting to move, thereby increasing the flow rate of the magnetic abrasive in disguised form, and the boss can drive the aluminum alloy die-casting to rotate, so that the magnetic abrasive can grind all directions of the aluminum alloy die-casting, which can not only further reduce the polishing dead angle, but also effectively improve the polishing efficiency.

[0008] Further, a first cylinder body and a second cylinder body are vertically arranged on the inner bottom plates of the overflow prevention bucket and the container bucket respectively. The bottom plate of the overflow prevention bucket is open at the position corresponding to the first cylinder body, and the bottom plate of the container bucket is open at the position corresponding to the second cylinder body. The second cylinder body is sleeved outside the first cylinder body. A connecting shaft is vertically and rotatably installed in the first cylinder body. The top end of the connecting shaft is connected to the top end of the second cylinder body, and a special-shaped shaft is fixedly connected to the bottom end of the connecting shaft. A support plate is arranged on the base below the load-carrying flat plate. A third cylinder body is vertically and rotatably installed in the support plate. The magnetic disk is coaxially fixed at the top of the third cylinder body. A transmission shaft is vertically and rotatably installed inside the third cylinder body. The top end of the transmission shaft is fixedly connected with a socket head matching the special-shaped shaft. The socket head penetrates through the load-carrying flat plate, and the special-shaped shaft is inserted into the socket head. The transmission shaft is connected to the first driving member, and the third cylinder body is connected to the second driving member.

[0009] With the above scheme, the first cylinder body is provided, which can effectively prevent the grinding liquid from overflowing, and the transmission system is ingeniously designed, facilitating the direct taking and placing of the overflow prevention bucket on the load-carrying flat plate.

[0010] Further, the first driving member includes a first motor. The first motor is vertically fixed on the base, and the main shaft of the first motor is connected to the bottom of the transmission shaft through a coupling.

[0011] Further, the second driving member includes a second motor, a driving pulley, a driven pulley and a belt. The second motor is vertically fixed on the base. The driving pulley is fixedly connected to the main shaft of the second motor. The driven pulley is fixedly sleeved on the third cylinder body. The driving pulley and the driven pulley are connected by the belt for transmission.

[0012] Further, a plurality of clamping protrusions are fixedly connected to the outer wall of the overflow prevention bucket. A plurality of limiting blocks are arranged on the load-carrying flat plate. A clamping groove is formed in the limiting block. The plurality of clamping protrusions can be clamped in the plurality of clamping grooves.

[0013] With the above scheme, the loosening of the overflow prevention bucket can be avoided, and the stability of the device during operation can be improved.

[0014] Further, the top surface of the convex platform is concave.

[0015] With the above scheme, the top surface of the convex platform is designed to be concave, so that there is a gap between the bottom of the aluminum alloy die-casting and the convex platform, facilitating the passage of the magnetic abrasive, and thus enabling the bottom of the aluminum alloy die-casting to be effectively polished.

[0016] The beneficial effects of the present invention are as follows: when in use, the aluminum alloy die-casting and the magnetic abrasive are placed in a container barrel, and the magnetic disk and the container barrel are driven to rotate in opposite directions. The rotation of the container barrel can drive the aluminum alloy die-casting to move, thereby increasing the flow rate of the magnetic abrasive in disguised form, and the boss can drive the aluminum alloy die-casting to rotate, so that the magnetic abrasive can grind the aluminum alloy die-casting in all directions, which can not only further reduce the polishing dead angle, but also effectively improve the polishing efficiency.
