Wire harness pitch changing device

The utility model discloses a wire harness pitch changing device which comprises a translation mechanism and a pitch changing positioning mechanism. The translation mechanism comprises a clamping seat for clamping a wire harness and a first linear module for driving the clamping seat to move along a first direction; the variable-pitch positioning mechanism comprises a first linear driving mechanism and a wire distributing plate in transmission connection with the first linear driving mechanism, a plurality of wire distributing guide grooves are formed in the wire distributing plate at intervals, and the wire distributing guide grooves are distributed in the first direction; the first linear driving mechanism drives the distributor plate to move towards the clamping base in the second direction, and the second direction is perpendicular to the first direction. And the first linear driving mechanism is used for driving the wire distributing plate to approach the wire harness along the second direction, so that
