Efficient feeding device of grinding machine

The utility model discloses an efficient feeding device of a grinding machine, which comprises a machining table and is characterized in that a grinding device is fixedly mounted on the back of the machining table, and a sliding platform is mounted on the surface of the machining table in a sliding manner. According to the scheme, in the process that a workpiece is pushed to the surface of the second table body along the pin roller, the clamping block plate is extruded, then the spring is compressed, when the workpiece penetrates through the surface of the clamping block plate, the spring drives the clamping block plate to reset, the workpiece is prevented from sliding down, then the driving motor drives the stud to rotate, and the transmission plate is matched to drive the second table body to ascend to a proper position. And finally, the workpieces are pushed to the surface of the sliding platform and clamped through the air cylinder clamping device, a worker can conveniently and directly push the heavy wor
