Description

Technical Field

[0001] The utility model relates to a grinding device, in particular to a grinding device, belonging to the technical field of zinc alloy door grinding. Background Art

[0002] Zinc alloy is an alloy composed of zinc with other elements added to it. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium, etc. Zinc alloy has a low melting point, good fluidity, easy welding, brazing and plastic processing, is corrosion-resistant in the atmosphere, and residual materials are easy to recycle and remelt, but the creep strength is low and it is easy to undergo natural aging and cause dimensional changes. It is prepared by the melting method and is formed by die casting or pressure processing. The zinc-steel gate is made of galvanized steel pipes of different sizes and thicknesses through welding, and is welded and formed according to the drawings. Then it is polished and put into a high-temperature oven for electrostatic powder spraying and coloring. Users can choose the appropriate color according to their own courtyard style. The flower pieces can be gilded, and the overall effect can be enhanced after embellishment; during the production of zinc alloy doors, a grinding device needs to be used to grind their surface;

[0003] After a lot of searches, I found: China Utility Model Patent Column: Publication No. 202221307985.9 A grinding device for zinc alloy door production, comprising a first box body, a first fixed plate welded to the inner wall of one side of the first box body, a low-speed motor is installed on the top of the first fixed plate by bolts, a vertical plate is welded to one side of the bottom inner wall of the first box body, a movable plate is slidably connected to one side of the bottom inner wall of the first box body, the vertical plate and the movable plate are rotatably connected to a rotating plate on the side where they are close to each other, and a connecting plate is provided on the side where the rotating plates are close to each other.

[0004] The device uses a supporting plate and a clamping plate to clamp the door panel to fix the door panel, and then the door panel is polished by a polishing device. Due to the obstruction of the supporting plate and the clamping plate, the polishing device cannot polish the clamping area of ​​the supporting plate and the clamping plate, which also results in a poor polishing effect of the door panel. When it is necessary to polish the clamped area of ​​the door panel, it is necessary to loosen the clamping mechanism, then move the door panel, adjust the clamping area of ​​the door panel, and re-fix it, which makes the polishing of the zinc alloy door very time-consuming and labor-intensive.
