Numerical control device for grinding machine

The utility model belongs to the technical field of grinder conveying equipment. The utility model discloses a numerical control device for a grinding machine. The problem that in the prior art, a numerical control grinding machine does not achieve automatic control over workpiece clamping operation, and consequently the use efficiency is reduced is solved. Proposed now is the following scheme, the device comprises a workbench, a vertical plate and two fixing plates are fixedly mounted at the top of the workbench. Transverse grooves are formed in the sides, close to each other, of the two fixing plates. Transverse plates are slidably mounted in the two transverse grooves correspondingly, a first motor and a second motor are fixedly mounted on the sides, away from each other, of the two fixing plates correspondingly, threaded rods are fixedly connected to output shafts of the first motor and the second motor correspondingly, and the outer sides of the corresponding threaded rods are sleeved with the two fixing
