Description

Technical Field

[0001] The present application relates to the technical field of sheet metal polishing, and in particular to a sheet metal shell polishing device. Background Art

[0002] Sheet metal is sometimes also called plate metal. Generally, some thin metal plates are plastically deformed by hand or die stamping to form the desired shape and size, and can be further formed into more complex parts through welding or a small amount of mechanical processing. For example, chimneys, iron stoves, and car shells commonly used in households are all sheet metal parts. Usually after the sheet metal shell is produced, the paint surface needs to be polished to maintain its beauty.

[0003] For example, a Chinese utility model patent with announcement number CN217800941U discloses a sheet metal shell polishing device, including a box body, a concave frame is fixedly connected to the top of the box body, a polishing mechanism is arranged at the center of the top of the concave frame, a moving plate is slidably connected to the center of the top of the box body, the left and right sides of the top of the moving plate are slidably connected to the concave plate, and a driving mechanism is arranged at the bottom of the inner cavity of the box body and at the rear end of the moving plate. The utility model drives the screw rod to rotate by setting a turning handle, the screw rod drives the limit plate to move downward, and the limit plate drives the first protective pad to move downward, so as to limit the automobile shell to avoid the phenomenon of position displacement, and protect the bottom of the automobile shell by the second protective pad to avoid the phenomenon of damage to the automobile shell. By setting the above structure, it has the advantage of better fixing effect, solves the problem of poor fixing effect of the existing polishing device, and can better meet the use needs of users.

[0004] With regard to the above-mentioned related technologies, the inventor believes that during use, the polishing device uses a screw to drive the limit rod to move downward to fix the car shell. When the size of the car shell is small, the two concave plates are moved closer to each other, so that the guide block can also slide in the guide groove. However, since it is inconvenient for the user to fix the guide block, it is easy for the two concave plates to shake, which causes the car shell to shift during polishing, reducing the polishing effect of the polishing device on the car shell and having poor practicality.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
