Description

Sanding mechanism

The present invention relates to a sanding mechanism.

The grinding head of the conventional grinding mechanism is made of a rubber material. When the edge of the product is polished, the grinding head is easily deformed due to the soft rubber material, which causes the edge of the product to collapse. In order to solve the above problem, it is necessary to add a protective jig at the edge of the polished product, fix the jig to the edge of the product, and polish the edge of the product while polishing the protective jig. However, the above solution requires an additional protective fixture, which makes the grinding process more complicated, and at the same time, the protective fixture increases the wear of the sanding head.

In view of the above, it is necessary to provide a sanding mechanism capable of preventing the edge of the product from collapsing and reducing the abrasion of the sanding head.

A sanding mechanism comprising a driving member and a sanding head rotatably connected to the driving member, the sanding head comprising a rotating body made of metal, a cushion made of plastic fixed to the rotating body, and fixed to the buffer The pad is away from the sandpaper on one side of the rotating body.

The grinding head of the grinding mechanism of the present invention comprises a rotating body made of metal, which will The cushion pad is fixed on the bottom surface of the rotating body, and the rotating body can improve the mechanical strength of the sanding head, and the sandpaper is not easily deformed during use, thereby avoiding collapse at the edge of the product when the edge of the product is polished.

1 is a schematic structural view of a sanding mechanism of the present embodiment.

Figure 2 is an exploded perspective view of the sharpening mechanism shown in Figure 1.

Referring to FIG. 1 and FIG. 2 , the polishing mechanism 100 of the present invention is mainly used for grinding the surface of a casing of an electronic device such as a computer, a notebook, a tablet computer, or a mobile phone to improve the surface finish of the casing. The sharpening mechanism 100 includes a driving member 10 and a sanding head 30 rotatably coupled to the driving member 10. The drive member 10 drives the sanding head 30 to rotate to polish the surface of the housing.

The driving member 10 includes a driving body 12, a rotating shaft 14 rotatably coupled to the driving body 12, and an elastic coupling 16 fixed to one end of the rotating shaft 14 away from the driving body 12. The driving body 12 drives the rotating shaft 14 and the elastic coupling 16 to rotate. In the present embodiment, the driving member 10 is a servo motor. It can be understood that the driving member 10 can also be a rotating cylinder.

The sanding head 30 is generally disk-shaped and includes a rotating body 32, a cushion 34, a fixture 36, and a sandpaper 38. In the present embodiment, the rotating body 32 is made of metal and has a disk shape. The top end of the rotating body 32 is fixedly connected to the elastic coupling 16 , and a plurality of fixing holes 322 are defined in the bottom surface of the rotating body 32 .

The cushion 34 is circular and has a diameter equal to the diameter of the bottom surface of the rotating body 32. The cushion pad 34 is made of a plastic material. In the embodiment, the cushion pad 34 is made of a superior glue. Made of, excellent glue has high temperature resistance, acid and corrosion resistance, shock absorption and so on. A plurality of stepped holes 342 are defined in the fixing holes 322 of the cushion pad 34 corresponding to the rotating body 32. It will be appreciated that the cushion 34 can also be made of rubber.

The fixture 36 is a screw for mounting the cushion 34 to the rotating body 32. The sandpaper 38 is a backing sandpaper having an adhesive on the back side, the diameter of which coincides with the diameter of the cushion 34.

During assembly, the rotating body 32 is fixed to one end of the elastic coupling 16 away from the driving member 10. The fixing member 36 sequentially passes through the stepped hole 342 of the cushion 34 and the fixing hole 322 of the rotating body 32 to fix the cushion 34 to Rotating on the bottom surface of the body 32. The sandpaper 38 is adhered and fixed to the cushion 34. In use, the driving body 12 of the driving member 10 drives the rotating shaft 14 and the elastic coupling 16 to rotate, thereby driving the grinding head 30 to rotate.

It can be understood that the fixing hole 322 and the step hole 342 can also be omitted. Accordingly, the cushion pad 34 is adhered to the bottom surface of the rotating body 32.

The elastic coupling 16 is mainly used to slow the vibration of the sanding head 30 to extend the service life of the sanding head 30 and improve the sanding effect. It can be understood that the elastic coupling 16 can also be omitted. Accordingly, the sanding head 30 is directly fixed to the end of the rotating shaft 14.

The grinding mechanism 100 of the present invention comprises a rotating body 32 made of metal, and a cushion 34 made of plastic is fixed to the bottom surface of the rotating body 32. The rotating body 32 improves the mechanical strength of the sanding head 30, and the sandpaper 38 is difficult to use when in use. The deformation avoids the collapse of the edge of the product when the edge of the product is polished.

In summary, the new model meets the requirements of the new patent, and the patent application is filed according to law. . However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art in the present invention should be included in the following claims.
