Embodiment 1

[0018] A processing method for thin aluminum parts, such as figure 1 The thin aluminum part shown has a large cylindrical section and a small cylindrical section connected with the large cylindrical section; the turning process is rough turning the outer circle of the large end, the outer circle of the small end, and the end face of the small end; the semi-finished turning of the outer circle of the large end, the small end End outer circle, which includes the following steps:

[0019] A. Keep the thin aluminum part 1 of the semi-finishing car, which is located at the chuck position on the outer circle side of the big end, and remove the workpiece;

[0020] B, placing the thin aluminum part 1 completed in step A for 3 days;

[0021] C. Use the three-jaw chuck to clamp the thin aluminum part 1 at the chuck position on the outer circle side of the big end, such as figure 2 As shown, finish turning the outer circle of the large end, the outer circle of the small end, and the e...

Embodiment 2

[0027] B. Place the thin aluminum part 1 completed in step A for 5 days; other features are the same as in Example 1.

Abstract

The invention discloses a processing method of a thin aluminum piece. The processing method comprises the steps as follows: A, a chuck position is retained, and a workpiece is dismounted; B, the thin aluminum piece is placed for 3-5 days; C, a large end excircle, a small end excircle and a small end surface are subjected to finish turning, and a central hole is drilled; D, a stepped hole in the side of the large end excrcle is subjected to turning; and E, a thin aluminum piece turning clamp is adopted to perform turning on the large end surface of the thin aluminum piece subjected to the stepped hole turning. Compared with the prior art, the processing method of the thin aluminum piece can solve the problems of poor turning stability and low qualified rate of a conventional piston cover plate.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for a thin aluminum part used for a piston. Background technique [0002] Aluminum pistons are usually composed of a piston body and a piston cover. There is a large-diameter aluminum piston. The piston cover of the aluminum piston is a thin aluminum part with a large diameter. Tolerance and coaxiality tolerance precision requirements are high. At present, the turning process of the piston cover plate is as follows: 1. Rough turning of the outer circle of the large end, outer circle of the small end, and end face of the small end; 2. Semi-finishing of the outer circle of the large end and outer circle of the small end; 3. Finishing of the large end Outer circle, small end outer circle; 4. Turn around, clamp the outer circle of the big end, and turn the end face of the big end. This processing method has the following problems in the production ...
