The invention discloses a process for inlaying alloy teeth of a rock drilling bit. The process comprises the steps of 1, selecting a good-quality high manganese round steel and processing the good-quality high manganese round steel into a liner bushing; 2, carrying out vacuum water quenching, tempering and heat preservation on the processed liner bushing, and then carrying out air-cooling treatment; 3, carrying out finish machining on an inner hole of the linear bushing; 4, performing thermal treatment on the linear bushing machined with the inner hole, and pressing the alloy teeth into the linear bushing under appropriate conditions; 5, performing high-speed shot blasting treatment on the teeth-inlaid linear bushing; 6, accurately grinding the outer circular surface of the teeth-inlaid linear bushing; 7, enabling the teeth-inlaid linear bushing to be in interference fit with teeth holes. The process for inlaying the alloy teeth of the rock drilling bit has the advantages that the liner bushing is arranged to sleeve the alloy teeth, so that the holding force is enhanced by enlarging the effective combination surface by increasing the length, and the magnitude of interference can be reduced appropriately without increasing the alloy cost, and therefore, the teeth can be fixed firmly, and also the drilling bit body and the alloy teeth can be protected against damage; meanwhile, under the protection action of the liner bushing, because the stress is basically eliminated in the process of inlaying the teeth in the linear bushing, the phenomena of alloy tooth breakage and steel body collapse are reduced remarkably, and the service life of the drill bit is prolonged.
