Abstract

The invention discloses a machining method for an aluminum alloy bearing seat of a new energy automobile. The machining method comprises the following steps of firstly, pre-milling a positioning surface, finely milling a process boss surface, and then finely milling the positioning surface, so that the influence of stress of a die-casting aluminum alloy on the flatness of a product is reduced, and the flatness of a mounting surface within 0.03 MM and the position requirements of assembly holes of the bearing seat and a motor shell within 0.05 MM can be ensured. According to the method, a bearing hole is firstly machined through a combined diamond boring cutter, then the on-line measuring function of a machine tool is adopted, after the coordinate position is accurately found, a bearing mounting hole with the diameter being D106 MM is machined, and the requirement for the position degree of 0.05 MM of the bearing mounting hole is met.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a processing method for a bearing seat of a new energy vehicle. Background technique [0002] At present, during the processing of new energy vehicle bearing housings, the diameters of the bearing holes on both sides are relatively large, the diameter of the center hole is 101 mm, and the diameter of the outer circle is 190 mm.
