Positioning assembly for charging pile shell production

The positioning assembly for charging pile shell production comprises a base, a mechanical arm is arranged on the upper end face of the base, the end, away from the base, of the mechanical arm is fixedly connected with two symmetrically-arranged fixing frames, and the ends, away from the mechanical arm, of the two fixing frames are jointly and fixedly connected with a working column. A working cavity is formed in the working column, a telescopic motor is arranged on the outer wall of the side, close to the mechanical arm, of the working column, a telescopic shaft is arranged on the telescopic motor, the end, away from the telescopic motor, of the telescopic shaft penetrates through the working column and the working cavity, and a plurality of conical tables arranged at equal intervals are fixedly connected to the telescopic shaft; the multiple conical tables are slidably connected into the working cavity. The charging pile shell can be conveniently positioned and fixed, then sufficient machining work of diffe
