Embodiment Construction

[0006] The present invention will be further described below through specific embodiments.

[0007] The processing method of the electric vehicle front shock absorber bottom tube of the present invention comprises the following steps:

[0008] Rough drill main hole;

[0009] Coarse expansion oil seal hole;

[0010] Finishing at both ends;

[0011] deep hole processing;

[0012] milling plane;

[0013] Outer circle hook gear ring groove;

[0014] Drill horizontal holes.

[0015] Compared with the processing method of the prior art, the processing method of the bottom cylinder of the front shock absorber of the electric vehicle of the present invention saves the two processes of rough drilling tail hole and fine twisting oil sealing hole, reduces the number of clamping times, and greatly improves Improve processing efficiency and improve product quality consistency.

Abstract

The invention discloses a method for machining a front damper bottom barrel of an electric vehicle. The method comprises the following steps: roughly drilling a main hole; roughly reaming an oil-sealing hole; finely machining the two ends; machining a deep hole; milling a plane; lathing an outer circle and hooking a ring washer groove; drilling a transverse hole. Compared with the prior art, the method has the advantages that two steps are omitted, the machining efficiency is increased, the clamping times are reduced, and the product quality consistence is enhanced.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a processing technology for the lower cylinder of the front shock absorber of an electric vehicle. Background technique [0002] Nowadays, electric vehicles have become one of the important means of transportation for people. The manufacturing equipment and methods of electric vehicles have become one of the important research directions in the field of mechanical manufacturing. In the prior art, the processing method of the bottom cylinder of the front shock absorber of an electric vehicle includes the following steps: rough drilling the main hole - rough drilling the tail hole - rough expansion of the oil seal hole - rough machining at both ends - deep hole machining - milling Plane—the outer circle of the car, the groove of the gear ring—the finely twisted oil seal hole——drill the horizontal hole. The process method has many procedures and poor quality consistency. ...
