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
The present invention relates to mechanical manufacturing field, particularly the processing technology of the low cylinder of a kind of electric motor car front damper.
Background technology
Nowadays, one of electric motor car important life vehicles having become people.The manufacturing equipment of electric motor car and method become one of important research direction of mechanical manufacturing field.In prior art, at the bottom of electric motor car front damper, the processing method of cylinder comprises the steps: slightly to bore main aperture, and------------------turning, hook ring washer groove---essence strand oil sealing hole---bore cross-drilled hole to milling flat to deep hole machining in two ends roughing slightly to expand oil sealing hole slightly to bore uropore.The operation of this process is many, and quality conformance is poor.
Summary of the invention
Based on above realistic problem, through repeatedly proving and long-term experiment, the invention discloses the processing method of cylinder at the bottom of a kind of electric motor car front damper, good by cylinder product quality uniformity at the bottom of damping before the electric motor car that the method is obtained.
The processing method of cylinder at the bottom of electric motor car front damper disclosed by the invention, comprises the steps: slightly to bore main aperture, and------------milling flat---turning hooks ring washer groove---bores cross-drilled hole to deep hole machining in two ends fine finishining slightly to expand oil sealing hole.
The processing method of cylinder at the bottom of electric motor car front damper of the present invention, technique reduces two compared to existing technology, improves working (machining) efficiency, reduces clamping times, improves product quality uniformity.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further described.
At the bottom of electric motor car front damper of the present invention, the processing method of cylinder, comprises the steps:
Thick brill main aperture;
Thick expansion oil sealing hole;
Two ends fine finishining;
Deep hole machining;
Milling flat;
Turning hooks ring washer groove;
Bore cross-drilled hole.
The processing method of cylinder at the bottom of electric motor car front damper of the present invention, technique processing method compared to existing technology, eliminates the thick uropore that bores and twists oil sealing hole two operations with essence, decrease clamping times, greatly improve working (machining) efficiency, improve product quality uniformity.
