Description

Practical clamp for positioning and processing end face through elliptical hole

Technical Field

The utility model relates to the technical field of machining, in particular to a practical clamp for positioning and machining an end face through an elliptical hole.

Background

The original cast iron cylinder body of the air conditioner compressor for the vehicle is processed by firstly processing the end face and the outer circle, then positioning and processing the process hole by the end face and the outer circle, and then semi-finishing the elliptical inner cavity by the end face positioning hole, but the mode has long working procedure and higher cost.

In order to reduce the processing procedure and the processing cost, the cylinder body of the automotive air conditioner compressor which is formed by powder metallurgy precision casting is formed by precision casting of an elliptical inner cavity, an outer circle and a valve face of a semi-finished product, and mechanical cutting processing is needed for the two end faces and each hole.

However, due to the characteristic of powder metallurgy die casting, verticality of the elliptic cavity and the end face and position degree of the hole system relative to the elliptic hole are required to be ensured, and other positioning modes are difficult to ensure besides positioning of the elliptic cavity.
