[0002] An automobile radiator is composed of three parts: a water inlet chamber, a water outlet chamber and a radiator core. The coolant flows inside the radiator core, and the air passes outside the radiator. The hot coolant cools down by dissipating heat to the air, while the cold air warms up by absorbing the heat dissipated by the coolant. A fan is installed on the outer wall of the radiator to enhance the heat dissipation effect. When the existing automobile radiator is processed, chamfering treatment needs to be carried out on the radiator core to facilitate the welding of the radiator core. The existing chamfering methods are mostly manual chamfering by workers. This method has low chamfering efficiency and there are certain differences in the chamfering quality, which is not conducive to the processing of the radiator. Therefore, we propose an automatic chamfering device for an automobile radiator core. Content of the Utility Model

The second guide rods 118 are fixedly connected to the second push plate 117. One side of the second threaded rod 116 away from the second push plate 117 is fixedly connected to a rotating handle 119. By rotating the rotating handle 119, the rotating handle 119 drives the second threaded rod 116 to rotate, so that the second threaded rod 116 can push the second push plate 117 to move in the horizontal direction. When the second push plate 117 pushes the radiator core towards the chamfering tool 10, the rotating chamfering tool 10 can chamfer the radiator core.

[0034] Specifically, in the present utility model, when chamfering the radiator core, the radiator core is placed between the limiting plate 12 and the clamping plate 15. When the first hydraulic cylinder 14 pushes the clamping plate 15 towards the limiting plate 12, through the mutual cooperation between the clamping plate 15 and the limiting plate 12, the radiator core is clamped. Then, rotate the rotating handle 119.
