Precise edge grinding machine for ultrathin tempered film

The utility model belongs to the technical field of tempered film production, and particularly relates to a precise edge grinding machine for an ultrathin tempered film, which comprises a base, a fixing plate is fixedly connected to the surface of the base, an electric push rod is mounted at the center of the surface of the fixing plate, the output end of the electric push rod penetrates through the interior of the fixing plate and is connected with a push plate, and a film clamping component is arranged on the push plate; two opposite limiting plates are slidably connected to the surface of the base, and a first bidirectional lead screw and a second bidirectional lead screw are transversely inserted into the base; two opposite sliding blocks are further connected into the base in a sliding mode. By rotating the adjusting bolt, the clamping plate can be pressed downwards to clamp the tempered film in the longitudinal direction, meanwhile, the two limiting plates move oppositely by rotating the first two-way l
