Processing method of parts with long shaft and thin wall and processing clamp thereof

Abstract

The invention discloses a machining processing method of parts with a long shaft and a thin wall, belonging to the technical field of mechanical machining. The processing method comprises the following steps: firstly selecting the required metal material, then performing baiting, thermal refining, roughly machining, ageing at high and low temperatures, half precisely machining and precisely machining, and finishing the machining after the passed inspection; during the half precise machining, the outer circle of the part with the long shaft and thin wall is preserved with the machining residue; during the precisely machining, an expandable shoulder plunger piston clamp is used for matching with the part to machine; the other end of the part is reserved with a technical handle and provided with a central hole so as to locate through the outer diameter of the clamp and the inner hole of the part; and the outer diameter of the clamp is regulated so that the outer diameter is properly matched with the inner hole of the part. By using the processing method, the problems that the part with the long shaft and thin wall is easy to deform during the mechanical machining, is incapable of reaching the requirement of the technical parameter, and is low in machining yield are solved.

Description

technical field [0001] The invention relates to a machining method for long-axis thin-walled parts, belonging to the technical field of machining. Background technique [0002] In the field of mechanical processing, the machining of long-axis thin-walled parts is very common, but it is easy to deform during processing, which is difficult, fails to meet the technical parameters, and has a low processing pass rate. For example, long-axis thin-walled parts such as plungers, The technical parameters of its processing are length: 61.5mm, wall thickness: 1.2mm, outer circle dimensional accuracy: 7th grade tolerance, surface roughness: Ra0.2. In the prior art, two kinds of long-axis thin-walled parts are processed. Program. [0003] Option 1: If figure 1 As shown, a process handle is reserved at the end of the part without a hole, and a center hole is punched on the process handle. At the end of the part with a hole, a 60° taper angle is processed at the hole. Except for the proc...
