Description

Technical Field

[0001] The utility model relates to a rivet feeding structure of an automatic slot punching and riveting integrated machine, belonging to the technical field of structure improvement of the automatic slot punching and riveting integrated machine. Background Art

[0002] A channel (Hafen channel) is an embedded component used in construction projects, typically used in conjunction with rivets to secure the connection. This requires a channel punching and riveting machine, which requires a rivet feeder to deliver the heated rivets to the riveting station.

[0003] For example, the Chinese utility model patent with authorization announcement number CN210188381U discloses a rivet feeding structure for a groove automatic punching and riveting machine. Although it can automatically deliver rivets to the riveting station, it uses a multi-group connecting rod matching structure, involving a large number of hinge shafts and hinge holes. Since a certain gap must be left between the hinge shaft and the hinge hole to ensure flexible rotation, the cumulative error of this structure setting is large, and the processing accuracy requirements for each connecting rod are very high. Not only is the production and processing difficult, but after a period of use, as the hinge shaft and the hinge hole wear, it often swings out of place. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a rivet feeding structure for an automatic punching and riveting machine for a groove having a relatively low production and processing difficulty and a relatively accurate swing position.

[0005] The rivet feeding structure of the automatic groove punching and riveting machine described in the utility model includes a mounting frame, one end of the mounting frame is fixedly connected to a hinged seat, the hinged seat is connected to a pin shaft, the pin shaft is rotatably connected to a rotating sleeve and a triangular plate, the rotating sleeve is fixedly connected to a driving seat and a swinging plate, the swinging plate is fixedly connected to a rivet clamping assembly, the other end of the mounting frame is hinged to a first telescopic component, the other end of the first telescopic component is hinged to the triangular plate, the triangular plate is also hinged to a second telescopic component, and the other end of the second telescopic component is hinged to the driving seat.

[0006] Furthermore, the pin shaft passes through the hinge seat and is threadedly connected with a locking nut. The connection between the pin shaft and the hinge seat is achieved by cooperating with the locking nut. The structure is simple and the connection is convenient. The pin shaft can be disassembled by disassembling the locking nut, thereby facilitating the maintenance or replacement of the pin shaft, rotating sleeve and triangle plate.

[0007] Furthermore, the first telescopic component is a telescopic cylinder, which has a simple structure and is easy to control.

[0008] Furthermore, the second telescopic component is a telescopic cylinder, which has a simple structure and is easy to control.

[0009] Furthermore, the rivet clamping assembly includes a finger cylinder fixedly connected to the swing plate, and the two fingers of the finger cylinder are fixedly connected to a clamping claw, and the two clamping claws are adapted accordingly. Through the action of the finger cylinder, the two fingers rotate relative to or oppositely, thereby driving the two clamping claws to clamp or close, so as to achieve clamping and loosening of the rivet.

[0010] Furthermore, the finger cylinder and the swing plate are fixedly connected by a set of hexagon socket bolts, and the finger cylinder and the swing plate can be separated by removing the hexagon socket bolts, thereby facilitating maintenance or replacement of the finger cylinder.

[0011] Working process and principle:

[0012] First, the rivet is clamped by the rivet clamping assembly, and then the first telescopic component is controlled to extend. Under the action of the pin shaft, the triangular plate and the second telescopic component are driven to move forward together. Then the second telescopic component is controlled to extend. Under the action of the drive seat, the rotating sleeve and the pin shaft, the swing plate can be driven to swing, thereby driving the rivet clamping assembly to accurately deliver the grabbed rivet to the riveting station.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The rivet feeding structure of the automatic channel punching and riveting machine described in the utility model greatly reduces the design number of hinge shafts and hinge holes, thereby effectively reducing the cumulative error, not only reducing the difficulty of production and processing, but also improving the accuracy of the rivet feeding position.
