Description
Technical field
The utility model relates to a kind of automobile and engineering machinery push-pull flexible shaft assembly.
Background technique
Automobile and engineering machinery all are to adopt punch press to plant towards riveter with the pressure hose of push-pull flexible shaft assembly and the riveted joint of metallic pipe coupling at present, divide upper and lower mould to rivet, upper and lower mould be shaped as hexagonal shaped or shape from all directions, counterdie is fixed on the static die set, patrix is fixed on the punch set that can move, when pressure hose and metallic pipe coupling riveted joint, punch set moves downward the impact sleeve joint, making sleeve joint produce plastic deformation pushes to pressure hose, make pressure hose and metallic pipe coupling close-coupled, can bear high pulling force.Owing to during towards riveting, have only above-below direction that metallic pipe coupling is produced impulse force, and the punching press time is short, the quick deformation in metallic pipe coupling place becomes hexagonal shaped or all directions shape after the punching press, the distortion of outer tube steel wire is intersected, and skewness, the ability that makes pipe joint bear pulling force reduces, also can cause Internal Hole Deformation simultaneously, the slip resistance when operating mode is moved of axle core increases, and is easy to generate clamping stagnation, stuck phenomenon, makes that the manipulation resistance is big, can cause a core fracture when serious, cause the push-pull flexible shaft life-span short.
After the outer skin at pressure hose two ends is peelled off certain-length at present in addition, also to put a steel bushing, when making pressure hose, steel bushing and sleeve joint riveted joint like this, thereby because of there being three surface of contact that the riveting intensity of sleeve joint is descended, sleeve joint to connect the power of taking off inhomogeneous, that rivets the rear sleeve joint connects the power of taking off between 3000N to 5000N, and difference is bigger.For preventing the inside contraction deformation of pressure hose endoporus, remove a joint pressure hose internal lining pipe besides, mend the pressure hose endoporus with a steel bushing or steel ring more afterwards, both increase cost of material and also increased cost of labor with drill bit.
Summary of the invention
The technical problems to be solved in the utility model is: the push-pull flexible shaft assembly that a kind of sleeve joint rivet force is even, tensile strength is high and the flexible axle life-span is long is provided, has solved above-mentioned prior art existing problems.
The technological scheme that solves the problems of the technologies described above is: a kind of push-pull flexible shaft assembly, comprise pull bar, guide sleeve, pressure hose, sleeve joint and place the interior axle core of pressure hose, rivet with pull bar respectively at described axle core two ends, described pressure hose two ends are connected with sleeve joint respectively, sleeve joint has internal taper hole, and the pressure hose wherein sleeve joint of an end is connected with guide sleeve.
Described sleeve joint adopts octahedral button riveting mode to be connected with pressure hose.
The middle through hole of described sleeve joint inside is a shoulder hole, connects by the internal taper hole that has between the shoulder hole.
The angle [alpha] of described internal taper hole is 15～35o.
A kind of push-pull flexible shaft assembly of the utility model, adopted hydraulic riveter axial push-pull effort to be converted into the principle of the even radial riveting of polylith molded sheet by interior external mold cone match, thereby make sleeve joint produce uniform radial plastic deformation, the pressure hose steel wire is difficult for the intersection distortion, and pressure hose and sleeve joint riveted degree are good.In addition, the utility model uses the sleeve joint that internal taper hole is arranged, and promptly existing steel bushing and sleeve joint fuse, and save the steel bushing or the steel ring of pressure hose endoporus simultaneously; Cost of material and cost of labor have been saved, through even radial riveting bell and spigot joint of polylith molded sheet and pressure hose the time, riveted joint face has only two surface of contact, has improved tensile strength greatly, pulling-out force is also relatively all evener, and the pulling-out force of sleeve joint reaches between the 8000N to 12000N.
Below, the technical characteristics to a kind of push-pull flexible shaft assembly of the utility model is further described in conjunction with the accompanying drawings and embodiments.
