Description

The eccentric corresponding riveted joint distributed in a kind of cross double row riveting hole

Technical field

The utility model belongs to the vehicle body technical field, is specifically related to the eccentric corresponding riveted joint distributed in a kind of cross double row riveting hole, is particularly useful for the riveting of aluminum alloy passenger vehicle sectional materials cage vertical butt joint or near normal joint.

Background technique

At present, aluminium vehicle body Bus Frame adopts aluminium alloy pipe to pass through welding or riveting method joint forming usually, and adjacent skeleton vertical butt joint and near normal are docked in the car load skeleton occupies very large ratio.The normal welding mode is that argon arc welding is carried out fillet welding to joint, because can causing the substrate intensity of aluminum alloy framework joint, welding fails, the antidetonation shear resistance of weld seam is poor, and the Welded equipment requirement is high, can produce the harmful matters such as smog, noise, arc light in welding process, bus body skeleton volume and span are larger, the artificial welding of many dependences, easily operating environment of pollution, affect practitioner's health.

Because there is above problem in the welding of aluminum alloy bus body skeleton, at present in the industry for the docking of aluminum alloy bus body skeleton, main way and research direction are riveted joint, at adjacent skeleton vertical butt joint place, adopt riveted joint angle aluminum profile extrusion mode to realize connecting, two outer vertical of angle aluminum profile extrusion contact with the framework section bar interface respectively, and have by certain regular riveted holes, realize that by rivet docking between the adjacent skeleton of angle aluminum profile extrusion and vehicle body fix, distribution rule according to riveted holes, its embodiment has following single center line to distribute and double symmetrical two kinds, defect is separately all arranged.

The first form: the single riveted holes on the attachment face of angle aluminum profile extrusion both sides is distributed on the center line of angle aluminum profile extrusion, and defect is to rivet poor reliability and inboard rivet operating space difficult treatment.Single riveted holes is distributed on the center line of angle aluminum profile extrusion, because the line between the center, riveting point can't form a plane, and all be positioned on straight line, this straight line forms the natural spin axis of linkage structure, easily produce the rotary oscillation around this axis between the surface of contact of angle aluminum profile extrusion and skeleton, the riveted joint poor reliability.The aluminum corner brace riveted joint that the sectional materials cage cross shaped joint adopts single center line to distribute, when segmentation beam both sides are stressed, the segmentation beam can swing along the rivet line with aluminum corner brace.Simultaneously, because rivet is distributed on the axis of angle aluminum profile extrusion, on two attachment faces, with the riveted joint space of first rivet near corner, influence each other, if realize riveted joint, after need guaranteeing the one rivet, rivet head is outside the riveted joint space of another rivet, and for different rivets, the minimum range of both sides rivet of closing on corner is also different, both need to increase the size of connecting plate, caused again the not general of connecting plate.

The second form, double or to arrange rivet symmetrical on two attachment faces of angle aluminum profile extrusion more, although adopt this kind of mode to form many rivet lines, riveting point can form plane, but dock for square tube aluminium section bar cross, if on the corner all adopt double rivet angle of attachment aluminium section bar, the riveting point of tubing both sides will with rivet axle center conllinear, when linkage structure is stressed, the pulling force that the conllinear that the conllinear rivet runs through formation is reverse, and on this makes a concerted effort path, the tubing side is the riveted joint perforate, the perforate periphery easily runs through surrender, therefore adopt the symmetrical aluminum corner brace of double rivet to carry out the crossing skeleton connection, there are defect in its reliability and bearing capacity.

Simultaneously, adopt the symmetrical aluminum corner brace of double rivet to connect the problem that also has inboard rivet operating space difficult treatment, and, adopt this kind of mode, the material area that significant need is larger and more number of rivets, cost is higher.

The model utility content

The problem existed in order to solve existing frame welding Placement, for the defect of existing aluminium tube skeleton cross angle of attachment aluminium section bar riveted structure, provide a kind of cross double row riveting hole the eccentric corresponding riveted joint distributed.

The technical solution adopted in the utility model is: the eccentric corresponding riveted joint distributed in a kind of cross double row riveting hole, it comprises vertical tube and the transverse tube of cross docking, the butt joint corner place of described vertical tube and transverse tube is equipped with four aluminum corner braces, the attachment face of described aluminum corner brace is connected with the interface contact of vertical tube and transverse tube respectively, have the riveted holes cooperatively interacted on the interface of described vertical tube and transverse tube and described aluminum corner brace attachment face, described vertical tube and transverse tube are fixed together by rivet is installed at the riveted holes place, eccentric corresponding layout of riveted holes on described each interface, eccentric corresponding layout of riveted holes on riveted holes on the interface of described vertical tube or transverse tube one side and the interface of opposite side on the other side.Be the both sides that riveted holes on each interface is distributed in the median plane vertical with this interface, be zigzag and arrange, and the riveted holes on two sides that oppose on the vertical tube of median plane one side or transverse tube also is zigzag and arranges on the residing cross section of heart line, hole.

In such scheme, the eccentric corresponding mal-distribution structure of arranging of riveted holes, make the docking structure of vertical tube and transverse tube form on the whole the force balance system, make total stressed evenly, firmly connect, that has avoided conventional riveted joint structure to occur runs through stressed and axial runout.

Further preferred structure, eccentric corresponding layout of the riveted holes on the aluminum corner brace attachment face of described vertical tube both sides, eccentric corresponding layout of the riveted holes on the aluminum corner brace attachment face of described transverse tube both sides.

Further preferred structure, the riveted holes on each attachment face of described four aluminum corner braces is zigzag and arranges.

Further preferred structure, on each attachment face of described aluminum corner brace, every row's riveted holes requires space apart from aluminum corner brace border and the satisfied riveted joint minimum that is not less than of range distribution each other.

The utility model adopts the eccentric corresponding riveted joint distributed in double row riveting hole to carry out the docking of aluminium tube skeleton, adopting riveted joint to substitute is welded to connect, avoided the stressed and axial runout that runs through of conventional riveted joint structure appearance, compact economic and reliable riveted joint face can be provided, strengthen join strength and reliability, realize the reduction of cost, improved the distribution in riveted joint space, structure has better versatility, improves mounting process, raises the efficiency.
