Dynamic auxiliary electrolyte feeding clamp and electrolyte feeding way for electrolytic machining of vane cascade channel of blisk

The invention relates to a dynamic auxiliary electrolyte feeding clamp and an electrolyte feeding way for electrolytic machining of a vane cascade channel of a blisk, which belong to the field of electrolytic machining. A clamp body comprises a main electrolyte inlet (8) and an auxiliary electrolyte inlet (9), wherein a first path of electrolyte flows from the main electrolyte inlet (8) to a first side face (18) of a tool cathode, and then enters from the side face to a machining clearance on a front end face (20) of the tool cathode; a second path of electrolyte enters from the auxiliary electrolyte inlet (9) to a supplementary electrolyte elongated slot (12) on following supplementary electrolyte, enters from the supplementary electrolyte elongated slot (12) to an outlet of the following supplementary electrolyte, and then enters the machining clearance on the front end face (20) of the tool cathode; the two paths of electrolytes are intersected at the machining clearance on the front end face (20) of the t
