Machining process of intermediate flange

Abstract

The invention relates to a processing technology of an intermediate flange, comprising the following steps: 1) Positioning a three-jaw chuck, clamping the blank surface of the small end of the workpiece, and finishing the large outer circle, end face, and two-stage internal stop of the large end of the workpiece by finishing turning 2) Position the three-jaw chuck, clamp the large end of the workpiece by 10mm to process the outer surface, and finish the small end of the workpiece by finishing the small outer circle and the end surface of the inner hole; 3) Place the small end of the workpiece downward , and put it into the overall embedded tooling, and use the large outer circle and inner end face of the large end of the workpiece to position and broach; the beneficial effects of the present invention are: improving the quality control ability of each process, merging the processing steps, reducing the turning steps, and shortening the product production cycle.

Description

technical field [0001] The invention belongs to the technical field of processing technology, and in particular relates to a processing technology of an intermediate flange. Background technique [0002] The intermediate flange product is one of the components of the heavy-duty series transmission assembly. It is used for the direct connection of the front and rear sections of the transmission shaft. As a connecting piece, it includes internal splines, end teeth, and the shape and position tolerance requirements of the end surfaces of the end teeth and the internal splines. Higher, brings certain difficulty to machining. [0003] as attached figure 1 As shown, in the existing technological process, the machining part has three turning processes, one spline pulling, and then one turning process; it has the following defects: [0004] 1. In the existing technical scheme, due to the problem of the positioning method, the process of pulling the spline, and the quality control ...

AI Technical Summary

Problems solved by technology

[0004] 1. In the existing technical scheme, due to the problem of the positioning method, the process of pulling the spline, and the quality control ability, the shape and position tolerance of the major diameter of the spline and the major end face can only be controlled at 0.15, which cannot meet the requirements of 0.05 and 0.08 required by the customer's drawings. Arrange OP5 process lathe processing, spline positioning car end face to meet product drawing requirements and ensure product quality

[0005] 2. In the overall joint plan, there are 4 car processing, many processes, long processing cycle (about 10 days), and high personnel cost (a total of 4 people are required)
