Description

Technical Field

[0001] The present invention relates to the technical field of saw chain production, and in particular to a four-rivet assembly production line for saw chain production. Background Art

[0002] A chainsaw is a tool that uses a saw chain to cut objects. A saw chain is a special toothed chain that performs both transmission and cutting functions and is the primary working component of a chainsaw. The saw chain consists of rivets, a guide tooth, a connecting piece, and a cutter head. During assembly, the guide tooth is placed over the rivet. The connecting piece and cutter head on one side of the guide tooth are then installed and riveted together. The chain is then flipped over to install and rivet the connecting piece and cutter head on the other side of the guide tooth, completing the saw chain. Existing production methods involve riveting two rivets simultaneously. However, because the rivet conveyor must be stopped during this process, riveting only two rivets at a time requires multiple stops, reducing work efficiency. Summary of the Invention

The receiving plate 708 can effectively receive the rivets in the guide tube 704, effectively preventing the rivets in the guide tube 704 from falling. After the receiving plate 708 moves following the mounting block 706, the receiving plate 708 opens under the action of the pneumatic clamp 707, and the rivets above it fall onto the tank chain 501 below the receiving plate 708. The rivets in the guide tube 704 fall under the force of gravity and abut against the rivets below. At this time, the tank chain 501 In a stationary state, the receiving plate 708 moves in the opposite direction under the action of the mounting block 706 and fits under the action of the pneumatic clamp 707. At this time, the rivet on the tank chain 501 is located in the notch of the receiving groove.
