The invention relates to workpiece fixing equipment. The workpiece fixing equipment utilizes a first electromagnet to adsorb a cover plate so as to fix a workpiece on a carrier, so that the workpiece is prevented from shifting or from being hit away by a cutter during the machining process; in addition, the cover plate directly presses the workpiece to enable the frame of the workpiece to be exposed outside, so that the frame of the workpiece can be machined at one time, the working procedure of the traditional reverse clamping is eliminated, and the machining efficiency is improved. Moreover, the workpiece fixing equipment is provided with an adsorption component for adsorbing the cover plate, and a first guide mechanism and a second guide mechanism move in the first direction and the second direction to drive the adsorption component to be close to or far away from the workpiece, so that the cover plate is put on the workpiece before machining and the cover plate is taken down after machining. Therefore, the workpiece fixing equipment can automatically pick up and place the cover plate, so that the machining efficiency is improved, and manpower is saved.
