although fastening piece kind and specification on existing market are various, single product all cannot be realized orthogonal clamping function mostly.Although also there is minority product also can realize function vertical and horizontal bidirectional clamping, be modular construction substantially, being made up of multiple parts is not single integration product, and these modular construction complexity, volume and weight are larger, processing difficulties, expensive.Its using scope has certain narrow limitation.
Model utility content
the purpose of this utility model is, a kind of orthogonal clamping bolt is provided, and realizes the function that orthogonal clamps, thereby overcome the foot of prior art to adopt integrated single structure to substitute existing assembling unit structure.
the technical solution of the utility model is achieved in that
a kind of orthogonal clamping bolt of the present utility model is that this orthogonal clamping bolt comprises screw rod and bolt head; Between screw rod and bolt head, be provided with cam.
in aforementioned orthogonal clamping bolt, described cam and screw rod and bolt head are structure as a whole.
in aforementioned orthogonal clamping bolt, the upper surface of described cam is oval, and one end is large cambered surface, and the center of circle of large cambered surface is coaxial with double-screw bolt, and the other end is little cambered surface, little cambered surface with between cambered surface, be connected through Archimedian screw curved surface greatly.
in aforementioned orthogonal clamping bolt, described cam side view is ship shape, and upper surface and the supporting plane of cam are plane, and the bottom, little cambered surface one end of cam is inclined-plane; The angle α of inclined-plane and horizontal plane is 35-55 degree.
in aforementioned orthogonal clamping bolt, the planeness of described supporting plane is less than 0.05mm, and the perpendicularity of supporting plane and screw rod is not more than 0.1mm.
in aforementioned orthogonal clamping bolt, the joint of described screw rod and cam lower end surface is provided with arc tool withdrawal groove.
in aforementioned orthogonal clamping bolt, the screw thread on described screw rod is metric thread, inch screw thread, U.S. standard screw thread, whitworth thread MJ screw thread or the screw thread standard of mating with any installation matrix screw thread.
owing to having adopted technique scheme, compared with prior art, the utility model replaces complex assemblies to realize the function of vertical and the orthogonal clamping of horizontal bidirectional with an integral fastener to the utility model.Adopt the utility model both to alleviate the weight of complete machine, make again maintenance get up very convenient.
