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 includes the large-end outer circle, small-end outer circle, and small-end end face of rough turning; End outer circle, which includes the following steps:

[0019] A. Keep the semi-finished thin aluminum part 1 at the chuck position on the outer circle side of the big end, and unload the workpiece;

[0020] B. Place the thin aluminum piece 1 that has completed step A for 3 days;

[0021] C. Use a three-jaw chuck to clamp the thin aluminum piece 1 at the chuck position on the outer circle side of the big end, such as figure 2 As shown, finish turning the big end outer circle, the small end outer circle, and the small end face, drill the center hole, and unload the workpiece;

[0022] D. U-turn, use a three-jaw chuck to clamp the thin aluminum piece 1 at the ch...

Embodiment 2

[0027] B. Place the thin aluminum piece 1 that has completed step A for 5 days; the 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 method for processing thin aluminum parts for pistons. Background technique [0002] An aluminum piston is usually composed of a piston body and a piston cover plate. There is a large-diameter aluminum piston. The piston cover plate of the aluminum piston is a thin aluminum piece with a large diameter. The outer circle size of the large and small ends of the piston cover plate Tolerance and coaxiality tolerance require high precision. At present, the machining process of the piston cover plate is: 1. Rough turning big end outer circle, small end outer circle, small end face; 2. Semi-finishing turning big end outer circle, small end outer circle; 3. Finishing big end Outer circle, small-end outer circle; 4. U-turn, clamp the outer circle of the big end, and car the big end face. This kind of processing method has the following problems in the production process: the f...
