Machining Method and Boring and Milling Tool of Turbocharger Gas Intake Shell

Abstract

The invention discloses a machining method and a boring and milling tool for turbocharger gas inlet shells. According to the machining method and the boring and milling tool, by designing and using the special boring and milling tool, parts are machined through an ordinary boring machine instead of a five-axis machining center, the production cycle of the turbocharger gas inlet shells is shortened, and the machining cost of the turbocharger gas inlet shells is reduced. The method includes the following procedures, namely, the first procedure of line drawing, the second procedure of first flange plate boring and the third procedure of second flange plate boring. The boring and milling tool comprises a base. A positioning mandrel and an installation plate are arranged on the base in an erected manner. The upper end of the positioning mandrel is matched with a positioning hole formed in the base. The lower end of the positioning mandrel is used for being embedded in a machining tool work table. The installation plate is located on one side of the positioning mandrel. Positioning pins are installed on the installation plate and are used for positioning first flange plates of the turbocharger gas inlet shells.

Description

technical field [0001] The invention belongs to the technical field of marine turbochargers, in particular to a processing method for a turbocharger gas intake shell and a boring and milling tool thereof. Background technique [0002] Introduction to the structure and requirements of CTA gas intake shell: [0003] a. The gas inlet casing is the key and heavy part of the turbocharger. Its quality directly affects the performance and life of the machine, especially the processing quality and relative position of the two flanges and each hole must be accurate, otherwise the combination It is difficult to assemble, its assembly quality is difficult to guarantee, and its machine performance, quality and service life are even more difficult to guarantee. [0004] b. This part is in the shape of an elbow, and the two flange ends and the circumferential direction have processing content. It is required that the centerlines of the two flanges are coplanar and intersect at 90 degrees...

AI Technical Summary

Problems solved by technology

[0006] a. The machine tool equipment of the five-coordinate machining center is huge, the system is complex, the power is large, the operating cost of the system is high, the operator's labor salary is high, and the production cost of the part unit is high.

[0007] b. Five-axis machining center machine tools involve a wide range of knowledge and are difficult, and the machining programs compiled are more complicated, requiring a good theoretical level and practical experience, and require a higher technical level and work skills for the operator.

[0008] c. Five-axis machining center equipment has high operating costs and higher initial investment costs. It is the key and key equipment of the factory. The quantity is very limited and the production cycle is long, which cannot meet the time requirements of users.
