Abstract

The invention relates to the technical field of flange processing used for an electric vehicle rear axle and especially relates to a flange processing drilling device and method used for the electricvehicle rear axle. The device comprises a bottom plate, side plates and a top plate. The left and right sides of the top of the bottom plate are symmetrically provided with the side plates. The upperends of the side plates are provided with the top plate. The upper portion of the right side wall of the side plate located on the right side is provided with a driving motor. The output end of the driving motor is provided with a first lead screw. The left end of the first lead screw passes through the right side plate and is rotatably connected to the left side plate. The thread portion of the first lead screw is cooperatively provided with a first nut. The top of the first nut is provided with a first slide block. In the invention, the functions of the drilling and clamping and positioningof flanges with different specifications used for the electric vehicle rear axle can be simultaneously realized, drilling efficiency is increased and processing time is saved. The structure is novel,the design is reasonable, the usage is convenient, and the device and the method have a high popularization value.

Description

technical field

[0001] The invention relates to the technical field of flange processing for electric vehicle rear axles, in particular to a flange processing and drilling device and method for electric vehicle rear axles. Background technique

[0002] The rear axle of an electric vehicle is the driving part for the wheel to rotate and is an important part for the vehicle to transmit torque. When the car is running, the torque output by the engine is transmitted to the rear axle shaft of the car through multi-stage transmission, and then transmitted to the wheels by the rear axle shaft of the car to push the car forward or backward. Therefore, it has the ability to withstand Impact, alternating play to fatigue load and torsion. This requires the automobile rear axle as a whole to have sufficient bending strength, shear strength and good toughness. In order to improve the strength of the rear axle flange of the electric vehicle and the stability during work, the flange and ...
