Automatic assembly device of captive nut

Abstract

The invention relates to the field of automatic assembly machines, and discloses an automatic assembly device of a captive nut, which comprises an assembly frame platform, a stamping die, a feeding device and a nut-feeding mechanism, wherein the assembly frame platform realizes fixation and movement of the whole device, the stamping device is positioned above the assembly frame platform, the pressing die comprises a pre-bending punch, a bending slanted sliding block, an upper die assembly jacking the punch, and a lower die assembly comprising a bottom plate, the feeding mechanism comprise a feeding mechanism fixing device driven by a first cylinder, a feeding mechanism movable device driven by a second cylinder, and a third cylinder in a horizontal direction, the third cylinder is connected with the feeding mechanism movable device, a nut-feeding mechanism comprises a fifth cylinder, a square push rod and a nut sliding chute, the push rod is driven to move in the nut sliding chute, and an output of the nut sliding nut extends into the stamping die. The invention realizes automatic assembly of the captive nut, has capabilities of effectively saving labor cost and increasing production efficiency, and is suitable for production of massive captive nuts.

Description

technical field [0001] The invention relates to the field of automatic assembly machinery, in particular to an automatic assembly device for cage nuts. Background technique [0002] Cage nuts, as a widely used assembly part, are used in the assembly of many mechanical equipment, and the demand has always been very large. [0003] The traditional cage nut assembly method is to remove the clamping shell from the material tape, then put the square nut into the clamping shell manually, and then completely bend the small bending angles at both ends of the clamping shell, and finally get an assembled Cage nuts are assembled manually, which has low production efficiency and consumes a lot of human resources. Currently, there are some assembly machines for individual assembly, but this type of assembly machine only changes manual assembly into machine assembly, which is still assembled one by one. To achieve automatic production, the production efficiency is still very low. Althoug...

[0003] The traditional cage nut assembly method is to remove the clamping shell from the material tape, then put the square nut into the clamping shell manually, and then completely bend the small bending angles at both ends of the clamping shell, and finally get an assembled Cage nuts are assembled manually, which has low production efficiency and consumes a lot of human resources. Currently, there are some assembly machines for individual assembly, but this type of assembly machine only changes manual assembly into machine assembly, which is still assembled one by one. Realize automatic production, but the production efficiency is still very low. Although manual assembly and single machine assembly can meet the needs of small batch production, they cannot meet the needs of mass production.
