Combined type auxiliary positioning assembly of bending machine

The utility model discloses a combined type auxiliary positioning assembly of a bending machine, and belongs to the technical field of bending machines. A combined type auxiliary positioning assembly of a bending machine comprises a machine body, a lower support and an upper pressing plate and further comprises a bending plate which is arranged below the upper pressing plate, driving hydraulic cylinders are arranged at the two ends of the top of the upper pressing plate, and the driving hydraulic cylinders are connected with the machine body through cylinder body supports. In order to solve the problems that an auxiliary positioning structure is an independent device outside a bending machine body, so that the overall occupied space of equipment is enlarged, a plate needs to be debugged for multiple times in the positioning process, and a clamping and fixing mode is not easy to adjust and use, two-stage progress operation can be realized by utilizing a small air cylinder to be matched with a movable bridging
