[0012] (1) The present invention discloses a device for positioning a special-shaped plate for a machine tool. A plurality of positioning holes are provided on an operating table. A plurality of fixing mechanisms are separately installed in the positioning holes, so that the fixing mechanisms can be installed on the top of the operating table, thereby facilitating the positioning of the fixing mechanisms. That is, before processing the special-shaped plate, the operator can first place the plate on the top of the operating table, and then place the base on the operating table according to the position of each side of the plate. A slide groove is provided in the base, and a fixing rod is passed through the inner wall of the base so that the end of the fixing rod can be threadedly installed in the positioning hole.
