The invention discloses a mechanical connection method for a magnesium alloy die casting and a heterogeneous material component, which is characterized in that in the production process of the magnesium alloy die casting, an embedded part made of a heterogeneous material is arranged at the connection position of the magnesium alloy die casting in advance, so that the embedded part is embedded in the magnesium alloy die casting through the die casting process; and then the connecting piece and the heterogeneous material component are installed through the embedded part to complete mechanical connection. The method has the effect that the deformation resistance of the joint of the magnesium alloy die casting and the heterogeneous material component can be better improved, and the connection strength and reliability are improved. The connecting structure is particularly suitable for being implemented and applied to an automobile chassis (a front bottom plate and a rear bottom plate) or a battery box shell and an automobile body frame piece connecting structure.
本发明公开了一种镁合金压铸件和异质材料构件机械连接方法,其特征在于,在镁合金压铸件生产过程中,在其连接位置预先设置一个异质材料的内嵌部件,使该内嵌部件通过压铸过程嵌合于镁合金压铸件中,再通过该内嵌部件安装连接件和异质材料构件完成机械连接。本发明具有能够更好地提高镁合金压铸件和异质材料构件连接处抵抗变形能力的效果,提高了连接强度和可靠性。尤其适合在汽车车辆底盘(前后底板)或电池箱壳体和车身框架件连接结构中实施应用。
