Automatic riveting apparatus

An automatic riveting apparatus comprising:

• a base having a support frame and a photoelectric contact point positioned thereon;
• a feeding device disposed on the support frame, said feeding device including a lower die, with a rivet die thereon, horizontally moveable along a first direction and contacting the contact point of the base at an operation position for actuating a riveting device,
• said riveting device including a riveting head aligned with the rivet dies
• when said rivet die is positioned at the operation position, said riveting head is actuated to move downwardly in a second direction perpendicular to said first direction;
• wherein
• movement of the lower die along the first direction and movement of the riveting head in the second direction are through cylinders.

A method of riveting a workpiece, comprising the steps of:

• providing a base with a supporting frame and a photoelectric contact point thereon;
• providing a feeding device with a lower die plate having a rivet die thereon;
• disposing a workpiece on the rivet die;
• pushing a button to horizontally move the lower die plate with the workpiece in a first direction by cylinder pressure until touching the contact point of the base;
• actuating a riveting device, by touch of the contact point, to move downwardly in a second direction wherein said riveting device includes a riveting head;
• moving said riveting head toward the rivet die which is vertically aligned and located under the riveting head and rivet with the workpiece therebetween by cylinder pressure so as to rivet the workpiece accordingly;
• successively and individually moving, by cylinder pressure, the riveting head and the lower die plate in directions opposite to the second direction and the first direction, respectively;
• and
• removing the riveted workpiece from the lower die plate.
