Flexible direct current converter valve power unit crimping positioning device

According to the flexible direct current converter valve power unit crimping positioning device provided by the utility model, a plurality of collision lock mechanisms are arranged on the side wall of the base in a sliding manner, so that the structure can realize the steps of self-locking and positioning, the structure is ensured not to be influenced by horizontal relative displacement in the crimping process, the crimping precision of the structure is further improved, and meanwhile, the production efficiency is improved. The structure can be placed at a preset position conveniently through the sliding plate, secondly, the GBT crimping assembly of the structure is provided with an eccentric locking wheel used for horizontally locking the IGBT crimping assembly, and the thyristor positioning device is provided with a cushion block used for adjusting the position of the thyristor positioning device, so that the structure can realize simultaneous crimping of the thyristor crimping assembly and the IGBT crimpin
