The invention discloses a self-drilling rivet. The self-drilling rivet comprises a rivet sleeve and a rivet mandrel; the outer surface of the rivet mandrel is sleeved and connected with the rivet sleeve; the top end of the rivet mandrel extends to a position above the rivet sleeve and is fixedly provided with a clamping section, and the bottom end of the rivet mandrel extends to the lower end of the interior of the rivet sleeve and is fixedly provided with a riveting section; breakage slots are formed in the middle of the outer wall of the rivet mandrel; the middle section of the rivet sleeveis an expansion portion; the top end of the rivet sleeve is fixedly provided with a sleeve end cap; the sleeve end cap is polygonal; a groove is formed in the joint of the rivet mandrel and the riveting section; and several groups of symmetrical fixing holes are formed in the outer wall of the rivet sleeve. The self-drilling rivet has the beneficial effects that self drilling can be performed withthe cooperation of an installed drilling component and the polygonal sleeve end cap, and the drilling method is convenient and simple; when the riveting section moves up, fixing blocks of the drilling component can be pushed out of the fixing holes; due to the action of upper cut slots, the upper end of the drilling component is divergent; only the drilling component needs to be manually removed;and the drilling component is convenient to fall off and can be recycled.
Description
technical field [0001] The invention relates to the field of rivets, in particular to a self-drilling rivet. Background technique [0002] A rivet is a nail-shaped object used to connect two parts or components with a through hole and a cap at one end. In riveting, the riveted parts are connected using their own deformation or interference. Before installing the rivet, it is necessary to open a rivet hole on the fixing part. The full name of the rivet hole is the rivet through hole. It is the hole used for the rivet on the parts connected by the rivet. It needs to be opened mechanically. However, in some special cases, there is no pre-opened rivet hole on the fixing member, and at this time, the rivet needs to be drilled by itself, and the prior art lacks the rivet that drills by itself. [0003] Aiming at the problems in related technologies, we propose a self-drilling rivet. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the defic...
