Tool for excavator base

The invention provides a tool for an excavator base. Comprising a rack, a supporting frame arranged on the rack and used for supporting and placing an excavator base, and an electromagnet adsorption device arranged on the rack and used for adsorbing and fixing the excavator base on the supporting frame. The pressing and fixing device is arranged on the rack and used for pressing and fixing the excavator base on the supporting frame from top to bottom; and the rotating device is used for driving the supporting frame to rotate around a rotating shaft of the supporting frame. According to the scheme, through the arrangement, two positioning and fixing modes of magnetic adsorption and physical pressing are adopted, the fixing stability and the position accuracy of all parts of the excavator base are further improved, then the machining effect is improved, meanwhile, the rotating device is matched, all positions of the parts can be machined, and the machining efficiency is improved. And the subsequent welding proc
