The invention relates to an auxiliary processing robot for pig trotter meat products. The auxiliary processing robot comprises a bottom plate, three hulling manipulators, a lifting supporting rod and fixing devices, wherein the hulling manipulators are linearly distributed along the lateral central axis of the bottom plate at intervals, and the lower ends of the hulling manipulators are fixedly connected with the bottom plate; the fixing devices are located directly over the hulling manipulators, and the fixing devices and the bottom plate are connected through the lifting supporting rod; and the lifting supporting rod can adopt an electric-driven push rod, a pneumatic push rod and a hydraulic pressure push rod, and the whole heights of the fixing devices can be adjusted by the lifting supporting rod. According to the auxiliary processing robot disclosed by the invention, nail hulls at pig trotter tips can be quickly removed, the mechanical automation degree is high, the removing speed is high, and the effects of being clean and free from residuals are realized. The problem that in the deep processing course of pig trotters, the working procedure of removing nail hulls at the pig trotter tips consumes massive labor force is solved, the production cost for deep processing of the pig trotters is saved, the function that batch mechanized operation for deep processing of the pig trotters is realized, and the production and making efficiency is improved.
