The invention discloses a method for repairing a moving cone of a cone crushing machine, belongs to a mine crushing device, and particularly relates to a crushing machine part. The method for repairing the moving cone by M220 bolt sticking comprises the following steps: 1, setting process hasps; 2, mounting a vertical lathe; 3, cutting away exposed bolts; 4, removing residual bolts in the moving cone and carrying out secondary processing by the steps as follows: 1) drilling for the first time, 2) expanding for the first time, 3) removing scraps, 4) drilling for the second time, 5) expanding for the second time, and 6) removing bolt residues; 5, removing the process hasps; and 6, reassembling. Compared with the prior art, the method has the advantages of novel concept, reasonable repair process, simple facilities, high efficiency, quickness in recovery, favorability for ore crushing production, and capabilities of repairing the old, utilizing the waste, making the best use of everything, saving the resources, reducing the spare part expense and lowering the production cost.
