Method for processing small cover shell of automobile parts

Abstract

The invention discloses a method for processing a small cover shell of automobile parts, which comprises the following steps: according to the requirements of a drawing, milling three planes A, B and C respectively and drilling, and expanding and reaming respective holes on the three planes while ensuring the holes meet the requirements on position degree; finely boring inner holes on left and right sides of the plane B according to the dimensions shown in the drawing while ensuring the requirements on center distance, perpendicularity and position degree, drilling phi18.5 holes with a depth of 17 millimeters from two sides and chamfering the holes while ensuring the two side holes meet the requirements on coaxiality; tapping 12-M8-7H threads with a depth of 14 millimeters (on three planes), M18*1.5-7H threads with a depth of 15 millimeters and 2-M20*1.5-7H threads with a depth of 17 millimeters; doing tests by using corresponding measuring tools; and packaging the small cover shell after deburring and cleaning small cover shell and applying oil on machined surfaces of the small cover shell and then warehousing the small cover shell. The method ensures that the product meets the requirements on coaxiality, perpendicularity, and position degree, greatly improves the qualification rate of the product, reduced cost and improves benefits.

Description

Technical field: [0001] The invention relates to auto parts, in particular to a processing method for the small cover shell of the auto parts. Background technique: [0002] The current small cover shell of auto parts cannot be guaranteed in terms of coaxiality, verticality and position requirements, which seriously affects product quality, low qualified rate of finished products, and high production cost, which affects the production, operation and development of enterprises. Invention content: [0003] The object of the present invention is to provide a method for processing the small cover shell of the auto parts, which can well overcome the defects in the above products. The purpose of the present invention is achieved in this way. The processing method of the small cover housing of the auto parts is characterized in that: milling the A surface: positioning with a large plane support nail, pressing the side with a positioning pressure plate, and milling the plane to en...
