Reinforcement cage manufacturing jig frame

The invention relates to the technical field of reinforcement cage manufacturing jig frames, in particular to a reinforcement cage manufacturing jig frame. The device comprises a supporting frame and limiting devices installed at the two ends of the supporting frame. According to the device, the two ends of steel bars are sequentially sleeved with the inner ends of the corresponding lantern rings, the lantern rings slide to adjust the positions of the steel bars, the positions of the steel bars can be arranged on the inner side of the inner ring in an array mode, the U-shaped rods are of elastic structures, after pressure is lost, the U-shaped rods automatically reset, the two arc-shaped attaching blocks are driven to be away from each other, and clamping grooves are clamped into the inner ends of the corresponding sliding rods again; at the moment, the arc-shaped attaching blocks and the inner ring are fixed again, so that the positions of all the steel bars with the determined positions are fixed, machining
