Example 1:

as shown in fig. 2-5, the embodiment relates to a bolt positioning feeding device, which comprises a mounting plate 1 and a bolt feeding assembly arranged on the mounting plate 1. The spring bolt pay-off subassembly is including setting up spring bolt pay-off board 2 and locating piece 3 on mounting panel 1. The bolt feeding assembly further comprises a bolt feeding cylinder 21 arranged on the mounting plate 1, and a track plate 22 arranged on the output end of the bolt feeding cylinder 21. The bolt feeding plate 2 is installed on the track plate 22, the bolt feeding plate 2 can move relative to the positioning block 3, a bolt feeding channel 23 arranged along the moving direction is formed between the bolt feeding plate 2 and the positioning block 3, a bolt locking hole 24 used for receiving a bolt from the tail end of a bolt material pipe is formed in the bolt feeding plate 2 above the bolt feeding channel 23, and a blanking hole 11 communicated with the tail end of the bolt feeding channel 23 is formed in the mounting plate 1. When the lock tongue is in the lock tongue feeding channel 23, the lock tongue feeding plate 2 is abutted against the side wall of the lock tongue. A stop dog 31 only allowing the lock tongue to pass through at a specific angle is arranged in the lock tongue feeding channel 23, and the stop dog 31 is matched with a lock tongue groove on the lock tongue. In the spring bolt assembling process, the lock core foot on the lock core tip needs to catch on the spring bolt groove on the spring bolt, consequently has strict restriction to the spring bolt groove assembling direction on the spring bolt, and above-mentioned spring bolt location material feeding unit is in order to accomplish promptly and screens the spring bolt groove orientation on the spring bolt, so adopts dog 31 and spring bolt groove looks adaptation in the above-mentioned scheme, only supplies the spring bolt to pass through with the specific orientation of specific angle spring bolt groove.

Above-mentioned technical scheme relates to a spring bolt location material feeding unit, among this spring bolt location material feeding unit, constitute spring bolt pay-off passageway 23 between spring bolt pay-off board 2 and the locating piece 3, and spring bolt pay-off board 2 can move 3 relative locating pieces. After the spring bolt gets into spring bolt pay-off passageway 23 by lock tongue hole 24, spring bolt pay-off board 2 offsets with the spring bolt lateral wall, and drive spring bolt antedisplacement and rotation in the motion process of spring bolt pay-off board 2, and dog 31 that sets up in spring bolt pay-off passageway 23 screens the spring bolt, just supplies the spring bolt to pass through with specific angle promptly, so guarantee to send the spring bolt above unloading hole 11 to through dog 31 and need keep at required assembly angle. Above-mentioned spring bolt location material feeding unit can carry out position location to the spring bolt of irregular feeding, standardizes subsequent spring bolt pay-off, realizes automatic spring bolt assembly.

In a specific embodiment, a first pressing block 32 is arranged on the positioning block 3, the first pressing block 32 is located at the upstream of the stop block 31, and the first pressing block 32 elastically acts on the lock tongue to enable the side wall of the lock tongue to abut against the lock tongue feeding plate 2. The height and thickness of the first pressing block 32 are matched with the bolt slot on the bolt. Along the direction of delivery of spring bolt pay-off passageway 23, the thickness of first compact heap 32 in spring bolt pay-off passageway 23 grow gradually to make first compact heap 32 be the inclined plane to the effect face of spring bolt. In the above scheme, the first compressing block 32 compresses tightly the lock tongue all the time, so that the side wall of the lock tongue is abutted to the lock tongue feeding plate 2, and the lock tongue is driven to move forwards and rotate in the moving process of the lock tongue feeding plate 2.
