Description

Technical Field

[0001] The utility model relates to the technical field of riveting machines, in particular to an automatic riveting machine with adjustable blind hole spacing. Background Art

[0002] An automatic riveting machine is a machine used to automate riveting operations. Riveting is a method of joining workpieces by passing a fastener such as a rivet or stud through a hole in two or more workpieces and then forming a head or other form of fastening on the other side of the workpiece.

[0003] The riveting machine consists of a stroke cylinder and a riveting machine head. Since the stroke of the stroke cylinder is a fixed distance, and the blind holes punched by the workpiece have different depths, when the blind hole depth exceeds the stroke of the stroke cylinder, the riveting machine cannot rivet the workpiece, and its versatility is poor. At the same time, since the workpiece usually punches a row of blind holes, the operator needs to manually push the workpiece for riveting, which reduces work efficiency. Utility Model Content
