Abstract
This fastening component, which is intended to assemble a first part and a second part, includes a body extending longitudinally along an axis, a head configured to allow the fastening component to be rotated about the axis, and a tip connected to the body. The body has a side wall including fastening means configured to fasten the body to the first and second parts. The tip has a side wall having a shape different from that of a surface of revolution. The tip and the body are connected by a cleavable area configured to be broken in order to detach the tip from the body.
Claims21
A fastening component intended for assembly of a first part and a second part, wherein the fastening component comprises:
- a body extending longitudinally along an axis,
- a head configured to allow a rotation of the fastening component about the axis, and
- a drilling tip linked to the body, wherein
- the body has a lateral wall comprising a fastener configured to fasten the body to the first part and the second part,
- the drilling tip has a lateral wall of a shape distinct from that of a surface of revolution, wherein the drilling tip has a non-threaded tapered distal end, from the non-threaded tapered distal end of the drilling tip, an increasing cross section of an elliptic, ovoid, or polygonal shape, and
- the drilling tip and the body are linked by a divisible area configured to be broken in order to detach the drilling tip from the body, wherein the drilling tip includes one or more radially protruding elements which radially protrude from the lateral wall of the drilling tip, and
- wherein the divisible area is an annular groove interposed between the fastener of the body and the one or more radially protruding elements of the drilling tip.
A method for assembling a first part and a second part via a fastening component, wherein the fastening component comprises:
- a body extending longitudinally along an axis, a head configured to allow a rotation of the fastening component about the axis, and a drilling tip linked to the body, wherein the body has a lateral wall comprising a fastener configured to fasten the body to the first part and the second part, the drilling tip has a lateral wall of a shape distinct from that of a surface of revolution, wherein the drilling tip has a non-threaded tapered distal end, from the non-threaded tapereda distal end of the drilling tip, an increasing cross section of an elliptic, ovoid, or polygonal shape, and the drilling tip and the body are linked by a divisible area configured to be broken in order to detach the drilling tip from the body, wherein the drilling tip includes one or more radially protruding elements which radially protrude from the lateral wall of the drilling tip, and wherein the divisible area is an annular groove interposed between the fastener of the body and the one or more radially protruding elements of the drilling tip, the method comprising the steps of:
- rotating the fastening component about the axis;
- drilling the first and second parts by means of the drilling tip;
- and
- breaking the divisible area after the drilling tip has drilled the first and second parts.
An assembly device intended for implementation of a method for assembling a first part and a second part via a fastening component, wherein the fastening component comprises:
- a body extending longitudinally along an axis, a head configured to allow a rotation of the fastening component about the axis, and a drilling tip linked to the body, wherein the body has a lateral wall comprising a fastener configured to fasten the body to the first part and the second part, the drilling tip has a lateral wall of a shape distinct from that of a surface of revolution, wherein the drilling tip has, from a distal end of the drilling tip, an increasing cross section of an elliptic, ovoid, or polygonal shape, and the drilling tip and the body are linked by a divisible area configured to be broken in order to detach the drilling tip from the body, wherein the drilling tip includes one or more radially protruding elements which radially protrude from the lateral wall of the drilling tip, and wherein the divisible area is an annular groove interposed between the fastener of the body and the one or more radially protruding elements of the drilling tip, the method comprising the steps of:
- rotating the fastening component about the axis;
- drilling the first and second parts by means of the drilling tip;
- and
- breaking the divisible area after the drilling tip has drilled the first and second parts, the device comprising:
- a bearing tool configured to cause breakage of the divisible area of the fastening component after the drilling tip of the fastening component has drilled the first and second parts,
- a counter anvil having a housing intended to shape a collar around the body of the fastening component.
