Embodiment
as depicted in figs. 1 and 2, this orthogonal clamping bolt comprises screw rod 1 and bolt head 2 to the structural representation of a kind of orthogonal clamping bolt of the present invention; Cam 3 is provided with between screw rod 1 and bolt head 2.Cam 3 is structure as a whole with screw rod 1 and bolt head 2.The upper surface 4 of cam 3 is oval, and one end is large cambered surface 5, and the center of circle of large cambered surface 5 is coaxial with stud, and the other end is little cambered surface 6, is connected between little cambered surface 6 with large cambered surface 5 through Archimedian screw curved surface 7.Cam 3 side view is ship shape, and upper surface 4 and the supporting plane 8 of cam 3 are plane, is inclined-plane 9 bottom little cambered surface 6 one end of cam 3; Inclined-plane 9 is 35-55 degree with the angle α of horizontal plane.The angle α of inclined-plane 9 and horizontal plane determines according to the clamping mode of link second 13 and the requirement that clamp component, and when link second 13 needs vertical clamping forces larger, the angle α of inclined-plane 9 and horizontal plane is greater than 45 °; When link second 13 needs horizontal-clamping power larger, inclined-plane 9 is less than 45 ° with the angle α of horizontal plane.Each component size depends on the value of the angle α of inclined-plane 9 and horizontal plane.The planeness of supporting plane 8 is less than 0.05mm, and supporting plane 8 is not more than 0.1mm with the perpendicularity of screw rod 1.To guarantee that supporting plane 8 is not less than 80% with assembling basal plane 14 surface of contact installing matrix 11, prevent wedge load and then affect product strength.Screw rod 1 is provided with arc tool withdrawal groove 10 with the joint of cam 3 lower end surface.Screw thread on screw rod 1 is metric thread, inch screw thread, U.S. standard screw thread, whitworth thread MJ screw thread or with the screw thread standard of installing arbitrarily matrix 11 screw thread and mating.
preparation method for the preparation of of the present invention a kind of orthogonal clamping bolt of above-mentioned orthogonal clamping bolt is, the method adopts intensity be greater than the shape memory alloy bar at high temperature mold pressing of 1175MPa or forge into clamping bolt blank, and the cold water this blank being put into room temperature or traditional cold oil of putting into room temperature obtain finished product through machine flinishing after cooling rapidly; Described finished product also can adopt intensity be greater than refractory alloy, titanium alloy, high tensile steel or the at high temperature mold pressing of Ultrastrength Steel bar of 1175MPa or forge into clamping bolt blank, and obtains through machine flinishing after being cooled rapidly by this blank.
fig. 3 is the application example figure of orthogonal clamping bolt 15 of the present invention.As seen from Figure 3, the tapped hole that orthogonal clamping bolt 15 is assemblied on assembling matrix 11 through link first 16 connects, and realizes vertical clamping to link first 16.The horizontal component that the inclined-plane 9 of assembly process cam 3 produces carries out lateral extrusion to link second 13, by link second 13 squeezing in the side of assembling matrix 11 convex platform 12 tightly.The present invention only adopts an orthogonal clamping bolt 15 just link first 16 and link second 13 can be fixed on simultaneously on assembling matrix 11, achieves the vertical and orthogonal clamping integration of horizontal bidirectional.
