Thin-wall piece lathe clamp

Abstract

The invention discloses a thin-wall piece lathe clamp which is used for solving the problem of workpiece deformation. The thin-wall piece lathe clamp comprises two clamps, namely a turning clamp and a lathe inner hole clamp, wherein the turning clamp is pressed on the end surface of a workpiece through a gland by taking the end surface of the workpiece as a reference surface, and the diameter of the gland is less than the nominal diameter of the workpiece. The lathe inner hole clamp is characterized in that a clamp body tightly clamps the excircle of the workpiece, and the clamp body is welded on a chuck jaw. The invention has the beneficial effects that the thin-wall workpiece does not deform, which satisfies processing technical requirements.

Description

technical field [0001] The invention relates to a clamp for machining, in particular to a clamp for thin-walled parts. Background technique [0002] The conventional gear production method is to clamp the inner hole and end face of the outer circle on the CNC lathe. For workpieces with relatively thick walls and small inner holes, this kind of fixture can meet the process requirements; but for thin walls and relatively small inner holes For large workpieces, if the above-mentioned fixture is used to clamp the inner hole of the outer circle, the outer circle will be deformed, and the inner hole will be elliptical, which cannot meet the process requirements. Contents of the invention [0003] The invention discloses a thin-walled vehicle fixture, which solves the above-mentioned workpiece deformation problem. The utility model thin-walled car fixture includes two sets of fixtures: the outer circle fixture of the car and the inner hole fixture of the car; the outer circle fi...
