Detailed Description

The invention is further illustrated by the following specific figures and examples.

As shown in fig. 1, the embodiment discloses a rivet pressing nut automatic feeding device, which mainly comprises a mounting bracket 1, a cylinder 2, a connecting plate 3, a blowing pipeline 4, a material blocking cover plate 5, a pin shaft 6, a torsion spring 7, a cover plate mounting plate 8, a blowing pipe fixing cover plate 9, a fastening screw 10 and the like.

As shown in fig. 1, the cylinder 2 is mounted on the mounting bracket 1, a piston rod end of the cylinder 2 is arranged vertically upwards, and the connecting plate 3 is mounted at the piston rod end of the cylinder 2; the blowing pipeline 4 is horizontally arranged and fixedly installed on the connecting plate 3, a blowing hole 4a is formed in the blowing pipeline 4 along the length direction of the blowing pipeline, the opening, located at the rear end of the blowing pipeline 4, of the blowing hole 4a is a nut inlet, and the opening, located at the front end of the blowing pipeline 4, of the blowing hole 4a is a nut outlet; blow the concave notch that is equipped with of terminal surface before the material pipeline 4, keep off the material apron 5 and install through round pin axle 6 in the notch, 7 suits of torsional spring are in on the round pin axle 6, 7 one ends of torsional spring are connected with blowing the material pipeline 4, and the other end is connected with keeping off the material apron 5, and torsional spring 7 orders about keep off the lower extreme of material apron 5 and plug up the nut export.

As shown in fig. 1, in the present embodiment, the blowing pipe 4 mainly includes a pipe body 4.1 and a pipe cover plate 4.2, and the blowing hole 4a is opened in the pipe body 4.1. So set up, conveniently blow the dismantlement and the maintenance of material pipeline 4.

In the embodiment, as shown in fig. 1, a blowing pipe fixing cover plate 9 is installed on the upper part of the inlet of the nut. So set up, conveniently blow the material pipe and be connected with the nut import to and the maintenance in later stage.

As shown in fig. 1, in this embodiment, a cover plate mounting plate 8 is installed at a position close to the notch at the top of the front end of the blowing pipe 4, and the pin 6 is installed on the cover plate mounting plate 8. Because round pin axle 6 need constantly rotate in the use, rather than connecting the easy wearing and tearing of complex part, often need change the maintenance, and here through installing round pin axle 6 on apron mounting panel 8, when the part wearing and tearing, only need change round pin axle 6, apron mounting panel 8 can, more convenient is favorable to reducing equipment use cost moreover.
