The invention discloses an auxiliary positioning device for a
metal plate bending
machine, and relates to the technical field of
metal plate bending machines. The device comprises a positioning plate, the surface of the positioning plate is rotationally connected with the inner side face of a positioning ring, the side, away from a supporting
assembly, of the positioning plate is fixedly connected with the output end of a transmission
assembly, the bottom of the transmission
assembly is fixedly connected with the bottom of the inner wall of a
barrel, and the outer side face of the positioning ring is rotationally connected with the inner side face of a ring base. The two fixing assemblies are fixedly connected to the sides, away from the
barrel, of the positioning plate and the positioning ring correspondingly, the supporting assembly is fixedly connected to the side, away from the
barrel, of the positioning plate, the positioning assembly is fixedly connected to the side, away from the barrel, of the positioning ring, and the supporting assembly supports the bottom of the
metal plate to prevent the metal plate from being twisted during bending; the metal plate rotates with the positioning assembly as the fulcrum, the bending position is determined, the situation that the bending position is not easy to control due to the fact that the density of the metal plate is uneven is avoided, the bending position is controlled, and the needed bent metal plate can be obtained.
