The application provides a grinding machine plate fixing device for fixing a plate on an electromagnetic chuck of a grinding machine, which comprises a base plate, a shell arranged on the base plate, a lifting frame arranged in the shell, an elastic member arranged between the lifting frame and the base plate, two groups of installation rails arranged on the base plate and capable of sliding relative to each other, two groups of clamping plates arranged opposite to each other on the installation rails, clamping grooves arranged on the clamping plates, and two groups of driving mechanisms arranged on the lifting frame and connected with the two groups of installation rails, so as to drive the installation rails to open and close during the lifting of the lifting frame. The device can control the lifting of the lifting frame under the conditions of power-off and power-on of the electromagnetic chuck, and drive the two groups of installation rails to move in opposite directions and open and close under the action of the driving mechanisms, so that the plate is quickly fixed or released, and the plate does not need to be manually fixed and installed, thereby effectively improving the working efficiency of grinding.
