Abstract

The invention discloses an automatic assembly machine for expansion bolts. According to the automatic assembly machine, a nut positioning station, a spring gasket positioning station, a flat gasket positioning station, an expansion sleeve positioning station, a screw positioning station, a screw screwing station, a finished product demoulding station and a mould cleaning station are uniformly distributed on the edge of an index plate; each station is provided with a fixed mould with the same structure; the outer side of each station is provided with a conveying device for each corresponding component of the expansion bolts; wherein an expansion sleeve input device is provided with an expansion sleeve directional conveyor of which the center is provided with a V-shaped directional conveying groove; an expansion sleeve directional plate is arranged in the middle part of the V-shaped directional groove; a movable rod is arranged on the rear side of the directional plate; a directional plate moving cylinder is arranged on the rear side of the expansion sleeve directional conveyor; the end head of the movable rod is fixed on the front end of the push rod of the cylinder; the expansion sleeve input device is high in work reliability and low in fault occurrence rate; and impurities in the fixed moulds can be cleaned by the mould cleaning station on the index plate, so that in a standardized expansion bolt assembly process, the positioning of each component is not affected by the impurities.

Description

technical field [0001] The invention belongs to the technical field of expansion bolt assembly machinery, and in particular relates to an automatic assembly machine for components of expansion bolts. Background technique [0002] Expansion bolts are commonly used fasteners in construction. Expansion bolts are composed of screws, expansion sleeves, flat washers, spring sheets and nuts. For a long time in the past, expansion bolts were produced by manual assembly, which has low production efficiency and high labor intensity. With the advancement of science and technology, some enterprises have developed expansion bolt assembly machines to replace manual assembly of expansion bolts with mechanical equipment, such as Chinese patent CN203317030U and Chinese patent CN202162552U disclose the technology of two kinds of expansion bolt automatic assembly machines. These assembly machines mainly install nut positioning station, spring pad positioning station, flat pad positioning stati...
