Abstract
The utility model belongs to the technology of plane assembly tooling, and relates to an expanded plug type one-way spring pressing and positioning pin, which comprises an expanded plug, a front washer, a spring, a rear washer, a pin body, a limit screw and a nut. The expanded plug is arranged in a center hole of the pin body; an end surface inner hole of the pin body is connected with male threads of the nut; a stop groove is arranged on the outer circumference of the nut; the limit screw is installed on the pin body and placed into the stop groove of the nut; the spring is in sleeve connection on an outer circle of the pin body; the rear end of the spring acts on a step surface of a pin through the rear washer; and the front end of the spring acts on a plane of a part through the front washer. The expanded plug type one-way spring pressing and positioning pin adopts a structure that the expanded plug is positioned at the positioning end, enables the positioning pin to realize one-way positioning part operation; the threads can realize part compression without longer distance of rotation; and the pressing and positioning pin can be applied to a seal structure or can realize one-man operation of part positioning in larger-area tooling. Besides, the nut is tightly compressed, positioning is reliable, and working efficiency is greatly improved.
Description
Technical field
The utility model belongs to the aircraft rigger packing technique, relates to a kind of bloated plug formula unidirectional spring 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, adopt at the location of holding down bolt and nut compressing member because the compressing member of design is most of now, compress or release process in need the rotation very long distance just can work, and for big frock, when locating, part need another people to cooperate to install nut could realize that bolt tightens, waste of manpower, it is lower that the location compresses efficient.
The model utility content
The purpose of this utility model is to propose the bloated plug formula unidirectional spring that a kind of location compresses efficient height, knot human-saving to compress locating stud.Technical solution of the present utility model is that locating stud is made up of core bar, preceding packing ring, spring, back packing ring, shank, stop screw, nut; Expand and plug in the center hole of shank, core bar places the center hole of shank, one end of core bar is connected with nut thread, the other end of core bar for core bar be the bloated plug of one, the end face endoporus of shank is threaded with nut, have locking trough on the excircle of nut, stop screw is installed on the shank and inserts in the locking trough of nut, spring housing is connected on the cylindrical of shank, the rear end of spring acts on the step surface of pin by the back packing ring, and the front end of spring acts on the part plane by preceding packing ring.
Advantage that the utlity model has and beneficial effect, the utility model adopts the structure of plug in the positioning end location that expand, make locating stud can realize unidirectional locating element operation, do not need rotation just can realize that apart from screw thread part compresses than long, can be applied in enclosed construction, can realize that maybe nut compresses than the one man operation of part location in the large size frock, the location is reliable, has improved the efficient of work greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model, and wherein, 1-A is a sectional view, and 1-B is the side view of 1-A.
Embodiment
Locating stud is made up of core bar 8, preceding packing ring 2, spring 3, back packing ring 4, shank 5, stop screw 6, nut 7; The plug 1 that expands places the center hole of shank 5, core bar 8 places the center hole of shank 5, one end of core bar 8 is threaded with nut 7, the other end of core bar 8 for core bar be the bloated plug 1 of one, the end face endoporus of shank 5 is threaded with nut 7, have locking trough on the excircle of nut 7, stop screw is installed on the shank 5 and inserts in the locking trough of nut 7, spring 3 is socketed on the cylindrical of shank 5, the rear end of spring 3 acts on the step surface of pin by back packing ring 4, and the front end of spring 3 acts on the part plane by preceding packing ring 2.
Using method of the present utility model is: when the location compresses part, be rotated counterclockwise nut 7, core bar 8 drives the plug 1 that expands and travels forward, and shank 5 front ends are replied original profile, and shank 5 is injected in the tool locating hole, dextrorotation turn nut 7, core bar 8 drives plug 1 motion backward of expanding, and the bloated plug 1 of core bar 8 expands shank 5 front ends, stops shank 5 to retreat, spring 3 compresses part, makes shank 5 play the effect of location tension.Reverse operating when withdrawing from location shank 5 realizes that the taking-up of part is pulled down.
