Full-automatic three-dimensional multipoint cold riveting assembly process engineering of die-casting aluminum alloy

Abstract

The invention discloses a full-automatic three-dimensional multipoint cold riveting assembly process engineering of die-casting aluminum alloy which relates to a full-automatic three-dimensional multipoint cold riveting special device. In the special device, a sliding table power mounting base and a workbench panel are respectively installed on a rack, a spin rivet power system is installed on a vertical Z-direction servo linear sliding table which is installed on the sliding table power mounting base, a workpiece spin rivet gripper is installed on a horizontal Y-direction servo linear sliding table which is installed on a horizontal X-direction servo linear sliding table, the X-direction servo linear sliding table is installed on the workbench panel, and the spin rivet power system is positioned above the workpiece spin rivet gripper. Compared with the prior art, the riveting speed of the invention is improved by 1.5-2 times, and the invention has the advantages of high riveting quality, high connection soundness, low error probability, wide adaptation range of product specification, high production efficiency, long life of snap heads, high riveting accuracy and the like.

Description

Technical field: [0001] The invention relates to a fully automatic three-dimensional multi-point cold riveting assembly technology of die-casting aluminum alloy. Background technique: [0002] In the production of automobile engines, die-casting aluminum alloy cylinder head cover riveting assembly assembly is often required, and it is multi-point riveting that is not on the same plane.
