Electric vehicle retarder shell body machining technology method

Abstract

The invention discloses an electric vehicle retarder shell body machining technology method. Firstly, a fixture is modified, and specially for a machining requirement of a vertical type machining center, a multi-face machining fixture is designed. A fixture base plate is controlled to rotate by 180 degrees through a numerical control rotating table, so that the different end faces of an electric vehicle retarder shell body on the fixture base plate required for being machined faces a machining area, the shell body does not need to be disassembled, one-time machining can be finished, the planeness of a machining face and a precision requirement of an aperture position can be guaranteed and the efficiency is improved, meanwhile the vertical type machining center is used, and the capital investment cost of equipment and the development cost of a cutter can be saved. According to the structure of the vertical type machining center and the multi-face machining fixture, technology processesare optimized, and the production efficiency can be improved well.

Description

technical field [0001] The invention belongs to the field of processing and manufacturing of auto parts, and in particular relates to a processing method for a reducer shell of an electric vehicle. Background technique [0002] The electric vehicle reducer shell is made of high-pressure aluminum alloy, with transmission gears inside, and the aperture and position accuracy are high; in the existing processing technology, the general processing method of the reducer shell is to use a horizontal machining center to process the upper and lower bearing holes and oil seals. Hole rotation processing, however, the cost of horizontal machining center equipment and corresponding tools is relatively high, and multiple sets of fixtures are required to be disassembled and clamped repeatedly to process different processing surfaces, which cannot guarantee the flatness of the processing surface and the accuracy of the hole position. Production efficiency is also not guaranteed. Contents ...
