Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in accompanying drawing 1-4, a kind of riveted joint bearing pin chain being provided with packing ring of the utility model, comprise outer plate 11, inner plate 12, described inner plate 12 is arranged at the inner side of outer plate 11, and outer plate 11, inner plate 12 are connected as one by Assembly of pin 13; Described Assembly of pin 13 comprises pin body 131, is arranged at the protruding fixing part 132 of pin body 131 one end, and the other end is provided with riveted joint fixing part 133, is provided with packing ring 14 between described riveted joint fixing part 133 and outer plate 11.
In the present embodiment, the outer wall of described pin body 131 is provided with guiding groove 134.The center of described riveted joint fixing part 133 is provided with positioning hole 135, and further, described positioning hole 135 is provided with the pin cap 136 be mated.Insertion part 1361 and positioning hole 135 interference fit of described pin cap 136 are fixed.
In the specific implementation, by auxiliary positioning part (not shown) by outer plate 11, inner plate 12 is fixed, require outer plate 11, the position, hole of inner plate 12 aligns, by pin body 131 successively through outer plate 11, after inner plate 12, and pass from outer plate 11 at this, at the sheathed packing ring 14 of the riveted joint fixing part 133 of pin body 131, when the protruding fixing part 132 of described pin body 131 contacts with the bottom of outer plate 11, by the riveted joint fixing part 133 of high-frequency induction coil (not shown) heating pin body 131, the edge of riveted joint fixing part 133 is made to become redness, now, be the external force that riveted joint fixing part 133 applies a setting by hydraulic hammer (not shown), not damage outer plate 11, inner plate 12, and the circularity of pin body 131 lower end is advisable.Apply setting external force after, described riveted joint fixing part 133 to packing ring 14 side extruding, thicker, until riveted joint fixing part 133 be connected on packing ring 14.Owing to being provided with guiding groove 134 at the outer wall of pin body 131, described guiding groove 134 is annular groove, is beneficial to riveted joint fixing part 133 and bends laterally.Finally, the pin cap 136 be mated is set in described positioning hole 135, the external force that described pin cap 136 needs hydraulic hammer to apply setting is equally inserted, and adopts insertion part 1361 and positioning hole 136 interference fit of pin cap 136, pin cap 136 can not be dropped after such insertion.
In addition, between protruding fixing part 132 described in the utility model and outer plate 11, be provided with packing ring 14, serve the effect of buffering external force, protection outer plate 11.The clamping bolt (not shown) with its screw-thread fit is provided with at described positioning hole 135; Particularly, needing to adopt threading apparatus to process internal thread in positioning hole 135, and clamping bolt is set establishing in female positioning hole 135, avoiding chain to rivet fixing part 133 unbalance stress when running up and the problem that comes off.
