Title:
EJECTOR ROD AUTOMATIC ALIGNMENT CONCENTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/005030
Kind Code:
A1
Abstract:
An ejector rod automatic alignment concentric device. The ejector rod automatic alignment concentric device comprises an ejector rod (3), and an association structure (1) of which the opening or the stroke is controlled by the ejector rod (3), wherein an acting surface, of the association structure (1), in interaction with the ejector rod (3) is provided with a step on which a spherical groove (5) that matches a spherical surface of one end of the ejector rod (3) is provided. An alignment mode provided by the ejector rod automatic alignment concentric device enables acting surfaces of an ejector rod (3) and an association structure (1) to be directly aligned, thereby directly ensuring the coaxiality of two parts; and indirect alignment by a spring is not needed, thereby simplifying an assembling process of a production line.
