Embodiment

[0028] The invention provides a technical solution: a machining process for the rear axle housing of an electric vehicle includes the following steps:

[0029] Step 1: Position the clamping device, clamp and fix the car rear axle housing on the milling machine;

[0030] Step 2: Milling, first rough mill the outer plane and outer circle of the flange at one end, then rotate the table 180°, rough mill the outer plane and outer circle of the flange at the other end, and then change the tool for fine milling;

[0031] Step 3: Boring, fix the car rear axle housing on the boring machine, first rough bore the inner hole and chamfer of the flange at one end, then rotate the worktable 180°, rough bore the inner hole and chamfer of the flange at the other end ;

[0032] Step 4: Milling, rough milling the large end plane of the automobile rear axle housing on the milling machine, and then change the tool to finish milling the large plane of the automobile rear axle housing;

[0033] St...

Abstract

The invention discloses an electric vehicle rear axle housing machining technology, and relates to the technical field of vehicle part machining, particular to an electric vehicle rear axle housing machining technology. After cleaning of a cleaning machine is completed, water inside and outside a vehicle rear axle housing is blown away through compressed air, then, the vehicle rear axle housing isput on a workpiece frame, the vehicle rear axle housing can be effectively prevented from being eroded by water, and the situation that the rear axle housing oxidizes and rusts is avoided. The electric vehicle rear axle housing machining technology is adopted to machine the electric vehicle rear axle housing, excircles and inner holes of flange plates at the two ends of the vehicle rear axle housing are high in coaxiality, moreover, parts are convenient to put and pick, workpiece positioning is accurate, the machining percent of pass is high, operation is easy, convenient and safe, the laborintensity of workers is low, the production efficiency is high, the cost is low, and a scientific method is provided for production and machining of products of the same kind.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a machining process for rear axle housings of electric vehicles. Background technique [0002] Most of the rear axle housings of electric vehicles on the market now use the production process of processing each group of weldments into finished products, then combining welding and calibration, or processing each group of weldments separately on a CNC lathe after welding. [0003] However, the existing processing method cannot guarantee the coaxiality difference between the bearing blocks at the two ends of the rear axle housing, and the separate clamping and processing require frequent operations, high labor intensity, low production efficiency, and high production costs. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a machining process for the rear axle housing...
