The invention discloses an electroplated diamond drill bit of a honeycomb structure. The electroplated diamond drill bit of the honeycomb structure is composed of a steel body and a working layer, wherein a metal honeycomb structural part serves as a stress framework of the working layer, conducting plates serve as inner and outer gauge protection to surround the honeycomb structural part, and deposited metal packaged diamond particles evenly adhere to the honeycomb structural part and the conducting plates; then inner and outer gauge protection blocks are embedded onto the steel body; and themetal honeycomb structural part is welded onto the steel body, treatment before electroplating is conducted, the conducting plates surround the metal honeycomb structural part to form the complete drill bit inner and outer gauges, after the drill bit is packaged and put into a die, the drill bit is put into nickel-cobalt electroplating liquid to be electroplated, the electroplating deposition rate is controlled, the depo
