Abstract
This invention provides an automatic assembly mechanism for riveting-type pull rivets, comprising an indexing turntable and, circumferentially arranged above it, a push-press bushing assembly station, a locking ring assembly station, a rivet assembly station, a core rod assembly station, a pressing station, and a unloading station. The push-press bushing assembly station is used to feed and push the bushing; the locking ring assembly station is used to feed the locking ring; the rivet assembly station is used to feed the rivet; the core rod assembly station is used to feed the core rod; the pressing station is used to press the push-press bushing, locking ring, rivet, and core rod and determine whether the pressed product is qualified; and the unloading station is used to place the pressed product in the corresponding position. The automatic assembly mechanism for riveting-type pull rivets of this invention can automatically feed, assemble, and automatically position and press four parts: core rod, rivet body, locking ring, and push-press bushing. It achieves fully automatic operation and solves the problem of high error rate caused by excessive manual operation in existing pull-type pull rivet assembly processes.
