Abstract
The invention discloses a reamed hole bolt provided with an outer ring. The reamed hole bolt comprises a threaded rod, the outer ring, a pressing plate and a nut, wherein the threaded rod consists of a taper shank and a screw rod; a first slope surface is arranged at the outer wall of the taper shank along the axial direction; a value range of included angle alpha between the first slope surface and the axis line of the taper shank is that alpha is greater than or equal to 2 degrees and less than or equal to 8 degrees; the screw rod is positioned at one side, having small outer diameter, of the taper shank; the taper shank and the screw rod are coaxial; a second slope surface fit with the first slope surface is arranged at the inner wall of the outer ring; one end of the outer ring is aligned to one end, having large outer diameter, of the taper shank; the other end of the outer ring stretches out of the end face of one side, having small outer diameter, of the taper shank; the nut is in threaded connection with the screw rod; and the pressing plate is positioned between the outer ring and the nut, and is arranged on the screw rod in a sleeving manner. The reamed hole bolt is simple and compact in structure, reasonable in design, simple to mount, convenient to dismount, low in cost, high in strength and long in service life; and a gap between the threaded rod and the outer ring can be eliminated, and a precise driving function can be exerted.
Description
Technical field
The present invention relates to technical field of mechanical transmission, refer to a kind of hinged bolts with outer shroud particularly.
Background technique
Hinged bolts is a kind of part of conventional compact siro spinning technology fastening effect, all manufacturings machinery must a kind of element.In usual work, the hinged bolts exceeding certain specification requires very high when mounted to quality of fit, installs difficulty.If precision does not reach requirement, the requirement of link transmission accuracy can not be met again, can using effect be affected.
Therefore, research and develop that a kind of structure is simple, the hinged bolts of operation easily with outer shroud seems necessary.
Summary of the invention
Problem to be solved by this invention will provide a kind of structure simple, compact exactly, the hinged bolts of band outer shroud reasonable in design.This device can eliminate the gap between screw rod and outer shroud, plays the effect of precision drive.
For solving the problems of the technologies described above, the hinged bolts of the band outer shroud designed by the present invention, it is characterized in that: comprise screw rod, outer shroud, pressing plate and nut, screw rod is made up of taper shank and screw mandrel, the outer wall of taper shank is vertically first domatic, first domaticly with the span of the angle α of the shaft axis of taper shank is: 2 °≤α≤8 °, screw mandrel is positioned at the side of the little external diameter of taper shank, taper shank and screw mandrel coaxial, outer shroud inwall be set to domatic with first coordinate second domatic, align with one end of the large external diameter of taper shank in one end of outer shroud, the other end of outer shroud stretches out the end face of the side of the little external diameter of taper shank, nut is connected with wire rod thread, pressing plate is between outer shroud and nut and be set on screw mandrel.
Preferably, first domatic be 3 ° with the angle α of the shaft axis of taper shank.
Further, taper shank and screw mandrel are formed in one.
Advantage of the present invention is mainly reflected in following several respects:
One, structure is simple, compact, reasonable in design;
Its two, the present invention by first domatic domatic with second between coordinate, eliminate the gap between screw rod and outer shroud, play the effect of precision drive;
Its three, the present invention installs simply, convenient disassembly, and cost is low, and intensity is high, long service life;
Its four, the present invention can replace some volumes large, difficulty, dismounting inconvenience and use the component of articulation bolt operation are installed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: screw rod 1; Nut 2; Pressing plate 3; Outer shroud 4; Taper shank 5; Screw mandrel 6.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but this embodiment should not be construed limitation of the present invention.
A kind of hinged bolts with outer shroud shown in figure, it is characterized in that: comprise screw rod 1, outer shroud 4, pressing plate 3 and nut 2, screw rod 1 is made up of taper shank 5 and screw mandrel 6, the outer wall of taper shank 5 is vertically first domatic, first domatic be 3 ° with the angle α of the shaft axis of taper shank 5, screw mandrel 6 is fixed on the side of the little external diameter of taper shank 5, taper shank 5 and screw mandrel 6 coaxial, outer shroud 4 inwall be set to domatic with first coordinate second domatic, align with one end of the large external diameter of taper shank 5 in one end of outer shroud 4, the other end of outer shroud 4 stretches out the end face of the side of the little external diameter of taper shank 5, nut 2 is threaded with screw mandrel 6, pressing plate 3 is between outer shroud 4 and nut 2 and be set on screw mandrel 6.
In addition, taper shank 5 and screw mandrel 6 are formed in one.
When the present invention works, rotating nut 2 left, nut 2 acts on pressing plate 3, pressing plate 3 extrudes outer shroud 4 left, and under rotating reactive force, screw rod 1 moves to right, first domatic and second domatic between mutually extrude, outer shroud 4 is expanded, eliminates the gap between screw rod 1 and outer shroud 4, play the effect of precision drive.
The content be not described in detail in this specification, belongs to the known prior art of those skilled in the art.
