AI Technical Summary
Existing drilling equipment for press-fit studs requires manual unloading after drilling, resulting in low processing efficiency.
A drilling equipment for through-hole press-fit studs was designed. By using transmission elements and a self-feeding mechanism, the limiting element is automatically reset after drilling, realizing the automatic feeding and collection of press-fit studs. Through the cooperation of telescopic rods, springs and linkage components, the press-fit studs after drilling are automatically dropped from the storage slot and collected.
It improves the drilling efficiency of press-fit studs, reduces manual intervention, and realizes automated material feeding and collection processes.
