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.

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.
