A single groove single-sided fastener comprises: a rivet consisting of a rivet head, a polish rod, a locking groove, a tail pulling groove and a tail tooth in sequence, and a lantern ring consisting of a sleeve and a dead head; a tail of the rivet is of a single groove short-tail structure, a ratio of a length of the tail pulling groove to a total length of the tail tooth is 0.1&#x2dc;1.5, an included angle between a bottom generatrix of the tail pulling groove and an axis of the rivet is &#x2212;30&#xb0;&#x2dc;0&#xb0;, two axial ends of the bottom of the tail pulling groove and the tail of the tail tooth are of a fillet transition structure, a ratio of a length of a straight part of the tail tooth to the total length of the tail tooth is 0.1&#x2dc;1.

Single groove single-sided fastener and installation method thereof

An intelligent riveting system comprising a hydraulic riveting tool (), a riveting position identification system, a riveting displacement detection system, a riveting pressure detection system and a central processing system, wherein the central processing system acquires image information and carries out position identification, encoding and storage to form riveting position data in one-to-one correspondence, acquires real-time displacement data and riveting oil pressure data of each riveting position to form real-time data corresponding to riveting displacement values and riveting pressure values, and compares same with a standard to carry out quality determination. By means of the intelligent riveting system, a riveting position and an installation parameter are automatically identified and acquired, and the riveting quality is automatically determined; and by means of storing data during riveting and installation, the traceability of rivet installation quality can be achieved.

Intelligent riveting system

The present invention discloses a riveting robot, comprising: a robot part provided on a chassis, and detachably coupled with a riveting tool part through a hydraulically quick change disk; a visual position identification part provided on a side of the hydraulically quick change disk and secured on the sixth axis of the front end of the robot part; an automatic rivet feeding part provided on a mounting baseplate which is secured on a chassis through a two-stage vibration damping structure; a riveter tailing material collection part used for collecting tailing materials produced during riveting; a riveting quality judgment part used for collecting riveting data, and processing and generating a riveting curve to realize judgment of the riveting quality. A riveting robot system provided in the present invention can realize unmanned quick mounting of a pulling rivet at a specific riveting position; a vibration damping structure effectively isolates interference of riveting operation of a robot from a vibration source; radial and axial damping mechanisms can absorb axial and radial impact energies during the process of rivet pulling and mounting, ensuring that the operating accuracy of the riveting robot system and service life of the riveting robot mechanism.

Riveting robot system

A hydraulic steel strapping machine for strapping a steel strip around a package, including a clamping and cutting section and a tensioning section. An objective of the present invention is to minimize the weight and the volume of the steel strapping machine. The clamping and cutting section comprises a clamping cylinder, disposed on a top position of a front end of the hydraulic steel strapping machine along a Z direction and supported by a support frame, for driving a linkage mechanism. A cylinder pin is disposed in the linkage mechanism along a X direction and is sleeved by a lifting lug fixed onto a bottom surface of a piston of the clamping cylinder. A pressing part is sleeved around the cylinder pin, a cutter, a return spring and a transverse cutter are disposed below the pressing part. The linkage mechanism comprises two groups of connecting rods.

Hydraulic steel strapping machine

The invention discloses a detachable double-locking riveting dismounting method and a pulling rivet. A lantern ring comprises a thin-wall hook section, a thick-wall locking section and a lantern ring head with an annular step from front to back. The rivet comprises a rivet head of an annular groove matched with the hook section, a front polish rod section, a knurling section matched with the locking section, a separating groove, a rear polish rod and a tail annular groove section from front to back. Double riveting is used by inserting the rivet and lantern ring from both sides; after riveting, the locking section and knurling section form radial locking, and the hook section is buckled to form axial locking. Simple detaching tools (e.g. front snap ring and center cylinder) are equipped to dismount rivets rapidly.
