The invention relates to an adjustable energy meter terminal crimping device. The technical problem to be solved by the invention is to provide an adjustable energy meter terminal crimping device having high verification efficiency. The invention aims to automatically verify the compatibility of the terminal crimping device with different energy meters of different specifications on a production line and automatically realize the automatic crimping and separation of the conductor terminals of a single electronic energy meter and corresponding wires of energy meter verification equipment. For solving the problem, the invention adopts a technical scheme that: the adjustable energy meter terminal crimping device has a substrate; a meter support and a push-pull linkage mechanism used for connecting and disconnecting wires automatically are arranged on the substrate; and a group of current and voltage ejector pins and auxiliary pins are arranged on the meter support. The device is characterized in that the substrate is provided with an adjusting unit for adjusting the distance between the current and voltage ejector pins and auxiliary pins. The device is mainly suitable for automatically crimping and separating the conductor terminals of the single-phase electronic energy meter and the corresponding wires of the energy meter verification equipment on an energy meter automatic verification production line.
