Chromium plating auxiliary tool

The utility model discloses an auxiliary tooling for chromium plating, which belongs to the technical field of metal surface treatment and comprises a base, the base is arranged in a groove and clings to the bottom and the side wall of the groove, a first through hole penetrating through the upper end face and the lower end face of the base is formed in the base corresponding to a sinking table on the groove, and a second through hole penetrating through the upper end face and the lower end face of the base is formed in the base. The device is mainly used for making the sinking table make contact with external electrolyte. Moreover, an auxiliary anode is also arranged in the base, and the auxiliary anode is mainly used for increasing the current density at the groove. According to the chromium plating auxiliary tool, the current density in the groove is increased through the auxiliary anode, then the electroplating efficiency of the sinking table is improved, rapid chromium plating of the sinking table is ach
