Abstract

The utility model discloses an automatic flip-over mechanism of a flip-over saw, comprising a grinding component consisting of a motor and a grinding wheel. The grinding component is fixed on the front end of a main shaft by a fixing member of a grinding head, the main shaft is rotatably mounted on a corner bearing base, a rear end of the main shaft is connected with a corner lever, a lower end of the corner lever is connected with a piston of a cylinder which is horizontally arranged and movably mounted on the corner bearing base, the retractable movement of the piston on the cylinder drives the corner lever and the main shaft to do progressive rotation, and then the grinding component on the fixing member of the grinding head is driven by the main shaft to vertically flip over. During the movement of flipping over, the components are stressed evenly and operated smoothly so that the components are not prone to be damaged and have a long service life. At the same time, the whole structure is simple and the installation and modification of the structure are quite convenient. Further, because the cylinder is horizontally arranged and the volume and a radius of each component are small, the volume of the whole structure is small, which is convenient for installation and transportation.
