This invention discloses an automotive heater core assembly device, comprising a base, a core mounting plate, a cylinder, a pressure plate, a fixing plate, an inclined plate, and a rotating wheel. The inner side of the rotating wheel at the bottom is inclined, and a movable rod inserted into the core mounting plate is pressed against the edge of the inclined surface. A pressure rod that passes through the core mounting plate and engages with and fixes the core is rotatably connected between the two movable rods. This invention achieves a comprehensive breakthrough in the efficiency, precision, and reliability of automotive heater core assembly through the deep integration of mechanical linkage and overload protection technology. Specifically, when the cylinder drives the pressure plate to press down, the inclined plate drives the movable rod to move horizontally synchronously through the meshing transmission between the toothed plate and the rotating wheel, so that the pressure rod accurately engages with the core gap, completing bidirectional fixation in both vertical and horizontal directions, shortening the assembly cycle. The cross-distributed connecting ropes and connecting rods constitute overload protection. When the pressure plate applies pressure close to the core's bearing limit, it automatically limits the downward stroke to avoid deformation and damage.
