Abstract
The utility model discloses a hinge system hole bolt of outband ring, including screw rod, outer loop, clamp plate and nut, the screw rod comprises teper -shank and lead screw, and the outer wall of teper -shank is axial first domatic for the edge, and the contained angle alpha's of the axial lead of first domatic and teper -shank value range is: 2 <= alpha <= 8, the lead screw is located one side of the little external diameter of teper -shank, and teper -shank and lead screw are coaxial, and the outer loop inner wall sets up to domatic with first domatic complex second, and the one end and the one end of the big external diameter of teper -shank of outer loop are alignd, and the other end of outer loop stretches out the terminal surface of one side of the little external diameter of teper -shank, and nut and lead screw threaded connection, clamp plate are located between outer loop and the nut and the cover is established at the lead screw. Its simple structure, compactness, reasonable in design, the clearance between screw rod and the outer loop can be eliminated, accurate driven effect is played, the installation is simple, and it is convenient, with low costs to dismantle, and intensity is high, long service life.
Description
Technical field
This utility model relates to technical field of mechanical transmission, in particular to a kind of hinged bolts with outer shroud.
Background technology
Hinged bolts is the part of a kind of conventional compact siro spinning technology fastening effect, all manufacturings machinery must a kind of element.In usual work, quality of fit is required significantly high by hinged bolts when mounted that exceed certain specification, installation difficulty.If precision does not reach requirement, the requirement of connector transmission accuracy can not be met again, result of use can be affected.
Therefore, research and develop a kind of simple in construction, operate hinged bolts with outer shroud easily and seem necessary.
Summary of the invention
Problem to be solved in the utility model seeks to provide a kind of simple in construction, compact, the reasonable in design hinged bolts with outer shroud.This device can eliminate the gap between screw rod and outer shroud, plays the effect of precision drive.
For solving above-mentioned technical problem, the hinged bolts with outer shroud designed by this utility model, it is characterized in that: include 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 that first vertically is domatic, the span of the angle α of the first domatic axial line with 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 are coaxial, outer shroud inwall be set to domatic with first coordinate second domatic, align with one end of the big 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 is set on screw mandrel.
Preferably, the angle α of the first domatic axial line with taper shank is 3 °.
Further, taper shank and screw mandrel are formed in one.
Advantage of the present utility model is mainly reflected in following several respects:
One, simple in construction, compact, reasonable in design；
Its two, this utility model is domatic with the second coordinating between domatic by first, eliminates the gap between screw rod and outer shroud, plays the effect of precision drive；
Its three, this utility model is installed simple, convenient disassembly, and cost is low, and intensity is high, long service life；
Its four, this utility model can substitute for that some volumes are big, installation difficulty, dismounting inconvenience and use the component of articulation bolt operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: screw rod 1；Nut 2；Pressing plate 3；Outer shroud 4；Taper shank 5；Screw mandrel 6.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail, but this embodiment should not be construed restriction of the present utility model.
A kind of hinged bolts with outer shroud shown in figure, it is characterized in that: include 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 that first vertically is domatic, the angle α of the first domatic axial line with taper shank 5 is 3 °, screw mandrel 6 is fixed on the side of the little external diameter of taper shank 5, taper shank 5 and screw mandrel 6 are coaxial, outer shroud 4 inwall be set to domatic with first coordinate second domatic, align with one end of the big 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 threadeded with screw mandrel 6, pressing plate 3 is between outer shroud 4 and nut 2 and is set on screw mandrel 6.
It addition, taper shank 5 and screw mandrel 6 are formed in one.
During utility model works, to anticlockwise nut 2, nut 2 acts on pressing plate 3, pressing plate 3 extrudes outer shroud 4 to the left, and under rotating reactive force, screw rod 1 moves to right, first domatic and second domatic between mutually extrude, make outer shroud 4 expand, eliminate the gap between screw rod 1 and outer shroud 4, play the effect of precision drive.
The content not being described in detail in this specification, belongs to the known prior art of those skilled in the art.
