Description
Technical field
The utility model relates to one and revolves riveting knot structure, especially relates to a kind ofly locking revolving riveting knot structure.
Background technique
Traditional clinching method utilizes the mode of knocking to make rivet end produce plastic deformation, this clinching method existing defects: the distortion being difficult to control rivet end, causes distortion uneven; In addition, because the load be carried on rivet is uneven, easily cause stress to concentrate, cause fastening insecure phenomenon.For above-mentioned defect, occur now revolving riveter skill.Revolving riveter skill is utilize rivet rod to rivet pressurized, and swings continuously around center until the clinching method of rivet shaping.It is convenient and swift for revolving riveting feature, is easy to batch operation.At present, revolve riveter skill and obtain general application in manufacturing.And in transmission part designing requirement, owing to needing to bear larger moment of torsion, have very high requirement to rivet force, the common requirement of revolving riveting knot structure and being difficult to meet its moment of torsion.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind ofly locking revolves riveting knot structure, can bear higher torque force and not easily loosen.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind ofly locking revolve riveting knot structure, comprise connector element and lower connector element, described upper member lower end is provided with the cavity adapted with lower member, Open Side Down for described cavity, the bottom of the madial wall of described upper member is provided with a circle depression, the structure at described depression and the top of lower member adapts, the bottom surface of the outer side wall of described upper member is provided with bending, described bending bends towards the center of bottom, the top of described lower member is the die of disc structure, die is evenly distributed with multiple locating column, on described die, the outer of plane is provided with multiple groove, described multiple grooves be evenly distributed on lower member upper plane and with locating column one_to_one corresponding, predetermined spacing is there is between described groove and locating column.
The bottom of described described lower member is the rivet rod of cylindrical structural, seamlessly transits between described rivet rod and described die.Columniform rivet rod is convenient to force, and seamlessly transits between rivet rod and die, connects more firm.
The upper end of described upper member is provided with the link of cylindrical structural, and described link and the lower end of upper member seamlessly transit.Columniform link is convenient to force, and the lower end of link and upper member seamlessly transits, and connects more firm.
Described groove is square groove, and the outer openings of groove.Groove the roughness increasing on the one hand surface is set, make to revolve riveting knot structure more firm, the upper member being also on the other hand can with lower member positioning locking, be not easy to loosen.
Described die is evenly distributed with eight locating columns, described die is evenly distributed with eight grooves.Eight grooves and eight locating columns, can be evenly distributed in the surface of die, stability is also better.
Compared with prior art, the utility model has the advantage of that the bottom of the madial wall of upper member is provided with a circle depression, depression can fasten the sidewall of lower member, lower member and upper member is blocked.The bottom surface of the outer side wall of upper member is provided with bending simultaneously, can further be locked by reinforcement member.On lower member plane outer on be provided with multiple groove and multiple locating column, the setting of groove and locating column, upper member and lower member are located mutually, can not rotate.The utility model can bear higher torque force, and lockedly between upper member and lower member not easily loosens.
