Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rivet gun accessories, and in particular relates to an automatic feeding structure for auxiliary rivet guns. Background Technology
[0002] In existing rivet gun applications, the traditional nut loading process relies primarily on manual operation. Operators need to frequently place individual nuts into designated positions on the rivet gun, a method with numerous drawbacks. Firstly, manual loading is inefficient, severely impacting overall production progress, especially in large-scale batch production where it becomes a key bottleneck restricting efficiency improvements. Secondly, prolonged repetitive manual operation easily leads to operator fatigue, resulting in decreased loading accuracy and increased defect rates. Furthermore, manual operation suffers from high labor intensity and production costs, making it increasingly difficult to meet the demands of modern automated production. Therefore, there is an urgent need for a structure capable of automated loading to improve rivet gun efficiency and reduce labor costs and intensity. Utility Model Content

[0026] Working principle:
[0027] Nut conveying stage: Nuts are stored in the nut hopper tube and move downwards along the tube due to gravity or other conveying forces. When the nut reaches the connection point between the hopper tube and the angled insertion hole of the nut chuck assembly, it enters the nut chuck assembly under the guidance of the angled insertion hole.
[0028] Nut fixing stage: The upper and lower chucks in the nut clamp assembly work together to fix the inserted nut in the position corresponding to the rivet gun hole, ensuring that the nut will not shift during subsequent operations and preparing for the riveting operation.
[0029] Chuck opening and resetting stage: The chuck opening assembly functions, with the upper and lower support blocks connected to the upper and lower chucks via the first hex socket screw. Under the constraint and guidance of components such as pins and cotter pins, when subjected to external force (such as the movement of the rivet gun), the upper and lower support blocks can move relative to each other, opening the chucks to allow the rivet gun to perform riveting operations. After riveting, under the action of elastic components such as tension springs, the tension spring rod drives the upper and lower support blocks to reset, restoring the chucks to their original state, preparing for the next feeding and riveting. The inclusion of bearing components, bearing caps, a second bearing, and shaft components ensures the smoothness of the opening and resetting process, reduces friction and wear, and improves the stability and service life of the structure. The entire working process is cyclical, realizing automatic nut feeding and continuous operation of the rivet gun.
