Detailed Description
The present invention will be further described with reference to the following embodiments, which are intended to illustrate the principles of the present invention without limiting the present invention in any way, and the present invention is not beyond the scope of the present invention.
With reference to the attached drawings.
The annular groove rivet connection pair with the pre-tightening function comprises a rivet 1 and a lantern ring 2, wherein the rivet 1 sequentially comprises a rivet head 1.1, a polished rod 1.2, an annular groove locking area 1.3 and a tail tooth 1.4, the lantern ring 2 sequentially comprises a flange 2.1 and a deformation area 2.2, and the connection pair further comprises a pre-tightening ring 3 located at the outer end of the lantern ring 2 during riveting and fastening.
The utility model discloses pretension ring 3 and lantern ring 2 are the extrusion deformable ring structure that has the same deformation hardness that the same material was made.
The utility model discloses pretension ring 3 has the same external diameter D1, D2 with lantern ring 2, and pretension ring 3 internal diameter D1 is greater than lantern ring internal diameter D2. In this embodiment, the dimension of the inner diameter d1 of the pre-tightening ring larger than the inner diameter d2 of the collar is 0.5 to 3 mm.
As shown, the preferred embodiment of the present invention is to add a pre-tightening ring 3 to the existing high strength ring groove rivet fastener, and the pre-tightening ring outer diameter D1 is the same as the collar outer diameter D2, i.e., D1 ═ D2, and the pre-tightening ring inner diameter D1 is greater than the collar inner diameter D2, i.e., D1> D2. The structure is pre-riveted for the first time through riveting the pre-tightening ring 3, so that certain pre-tightening force is generated between the connected pieces to be connected and fixed, and after other operation operations are completed, the riveting lantern ring 2 is fastened and riveted for the second time to obtain final clamping force. The same design of external diameter has guaranteed that installation pretension ring 3 and lantern ring 2 use the riveting tool of same model specification to accomplish, and pretension ring 3 internal diameter D1 is greater than lantern ring internal diameter D2 design and makes the first time rivet pretension ring 3 accomplish the back, by obtaining certain pretightning force between the connecting piece, and pretension ring external diameter D1 reduces simultaneously, and when D1 reduced and guaranteed the second time rivet lantern ring 2, riveting tool and pretension ring 3 do not take place to interfere or the instrument extrudees the lantern ring 2.
The existing high-strength annular rivet fastener can not realize the pre-tightening function in the installation process of a connecting piece, and can only obtain the final clamping force through one-time riveting of a special riveting tool. The utility model discloses annular rivet fastener with pretension function divides twice riveting, and the first time is through riveting pretension ring 3, makes and is produced certain pretightning force between the connecting piece and carries out the pre-connection, accomplishes other operation back, and the rethread second time is riveted and is made the lantern ring 2 obtain final clamp force.
The mounting tool mainly comprises a special riveting tool and a tool power source. The riveting steps are as follows:
installing a pre-tightening ring:
(1) the rivet 1 is inserted through the mounting hole, and the lantern ring 2 and the pre-tightening ring 3 are sleeved in sequence from the tail part of the rivet 1.
(2) The tail teeth of the rivet 1 are inserted into the riveting tool.
(3) Applying axial force to the rivet 1 by using a riveting tool, and simultaneously radially extruding the pre-tightening ring 3, wherein the deformation length of the pre-tightening ring is at least 90% of the length of the pre-tightening ring, and only finishing the installation of the pre-tightening ring;
mounting a lantern ring:
(1) the tail tooth of the rivet 1 is inserted into the riveting tool again.
(2) The rivet 1 is axially forced using a riveting tool while radially compressing the collar 2 until the riveting tool head contacts the collar 2 flange, at which point the collar installation is complete.
The utility model discloses connect vice brokenly to tear open and adopt the brokenly instrument of tearing open of conventional rivet, will be with the cutting of pretension ring brokenly tear open again with the lantern ring brokenly tear open can.
The utility model discloses the installation of annular rivet structure with pretension function needs to carry out riveting twice, and needs install pretension ring 3 earlier, reaches the pretension purpose of installation, installs lantern ring 2 again, and current structure only needs once to install, can't realize the pretension purpose of installation.
In the actual work progress, to some connection structure complicated and special requirement, if do not in advance to the part preinstall, then the mounting hole skew appears in riveting connection's later stage probably, causes to connect fastening construction and can't go on, adopts the annular groove rivet structure that has the pretension function to fix a position, preinstall to each part, can avoid the dislocation of mounting hole like this.
In addition, to the structure that the straightness that hangs down between the connecting piece requires height, if do not do the location installation in earlier stage, wait to the whole slope that can appear of construction later stage connecting piece, the phenomenon that collapses can take place for serious person. Causing a great loss of manpower and financial resources. The annular groove rivet fastener with the pre-tightening function can well solve the problem of pre-tightening fixation.
