Abstract
The utility model belongs to the technology of plane riveting assembly and relates to a stop block type one-way nut compacted positioning pin. The stop block type one-way nut compacted positioning pin consists of an eccentric stop block [1], a shaft [2], a nut [3], a pin body [4] and a handle [5], wherein the eccentric stop block [1] is arranged in an arc groove at the front end of the pin body [4] through the shaft [2]; the handle [5] is arranged in a drilled hole at the rear end of the pin body [4]; and the nut [3] is arranged on the pin body [4] through screw threads. Parts can be unidirectionally positioned through the pin; the pin can be applied to a sealed structure to use; operation by one operator in positioning the parts in a large-area tool can be realized; the pin is simply operated; compacting efficiency can be greatly improved; and the pin has certain practical application value.
Description
Technical field
The utility model belongs to aircraft riveted joint mounting technology, relates to a kind of chock formula One-way nut and compresses locating stud.
Background technique
In the riveted joint assembly tooling of aircraft product, need a large amount of compressing members, in prepackage, assembling, riveted joint and the parts undercarriage process of part, need often to compress repeatedly or unclamp some compressing members.The compressing member of art designs is most of now adopts at the location of holding down bolt and nut compressing member, compress or release process in need the rotation very long distance just can work, and for big frock, when part is located, need another people to cooperate just and can finish fitting operation, therefore waste of manpower, it is lower that the location compresses efficient.
Summary of the invention
The purpose of this utility model is: propose a kind ofly quick, easy to operate, location is installed compresses the high chock formula One-way nut of efficient and compress locating stud.
The technical solution of the utility model is: a kind of chock formula One-way nut compresses locating stud, it comprises eccentric chock, axle, nut, shank, wherein, the shank front end has arc groove, and be provided with the eccentric chock of arc groove do rotation relatively by axle, described nut is set on the shank by being threaded.
The end of described shank is provided with handle by drilling hole transverse.
The utility model has the advantages that: the utility model chock formula One-way nut compresses the relative position relation of locating stud by eccentric chock and shank, realize locating element, and be fixed or unclamp dismounting by nut, it is simple to operate, can realize unidirectional locating element operation, can be applied in enclosed construction, maybe can realize one man operation than part location in the large size frock, and nut compresses, and the location is reliable, has significantly improved working efficiency.
Description of drawings
Fig. 1 is the structural representation that the utility model chock formula One-way nut compresses locating stud one better embodiment;
Fig. 2 is the plan view of Fig. 1,
Wherein, the eccentric chock of 1-, 2-axle, 3-nut, 4-shank, 5-handle.
Embodiment
Below by specific embodiment the utility model is described further.
See also Fig. 1 and Fig. 2, wherein, Fig. 1 is the structural representation that the utility model chock formula One-way nut compresses locating stud one better embodiment, and Fig. 2 is the plan view of Fig. 1.Described chock formula One-way nut compresses locating stud and comprises eccentric chock 1, axle 2, nut 3, shank 4 and handle 5.Wherein, the shank front end of locating stud has arc groove, and is provided with the eccentric chock 1 of doing rotation in can relative positioning pin arc groove by axle 2, and under action of gravity, this off-centre chock 1 can skid off in arc groove.Described nut 3 is set on the shank 4 by being threaded, and handle 5 is arranged on the end of shank 4 by drilling hole transverse.
When the utility model chock formula One-way nut compresses locating stud work: need the location to compress part, then by handle 5 rotation shanks 4, make under the effect of eccentric chock 1 in gravity and locating stud arc groove and keep a linear state with shank 4, shank 4 from being arranged, part one is sidelong in the tool locating hole, then with shank 4 Rotate 180s °, make eccentric chock 1 under the effect of gravity with 4 one-tenth plumbnesss of shank, eccentric chock 1 blocks the frock hole wall can't return shank 4, fastening nut 3 compresses part, thereby realizes compressing and the locating element effect.When unclamping part, unclamp nut 3, with shank 4 Rotate 180s °, eccentric chock 1 under the effect of gravity with shank 4 state that is in line, recall shank 4 again, realize the releasing orientation of part, thereby realize compressing fast and unclamping of part, very convenient quick.
The utility model chock formula One-way nut compresses the relative position relation of locating stud by eccentric chock and shank, realize locating element, and be fixed or unclamp dismounting by nut, it is simple to operate, does not need rotation just can realize that apart from screw thread part compresses than long, and can realize that the one man operation of unidirectional or big surface parts location installs, can be applied in enclosed construction, and nut compresses, and the location is reliable, has significantly improved working efficiency.
Claims (2)
1. a chock formula One-way nut compresses locating stud, it is characterized in that: comprise eccentric chock [1], axle [2], nut [3], shank [4], wherein, shank [4] front end has arc groove, and be provided with the eccentric chock [1] of arc groove do rotation relatively by axle [2], described nut [3] is set in by being threaded on the shank [4].
