Abstract
The utility model belongs to the technique of aircraft assembly tooling and relates to a ball type unidirectional spring compressing positioning pin, which is composed of a steel ball, a limiting block, an ejector rod, an outer spring, a front gasket, a back gasket, an inner spring, a pin body and a pressing handle, wherein the limiting block is provided with screw threads and installed at one end of the ejector rod; the pressing handle is mounted at the other end of the ejector rod in threaded mode; the inner spring is sleeved on the ejector rod; the bore of the pin body is a stepped hole; the inner spring acts in the stepped hole; the outer spring is sleeved on the excircle of the pin body; one end of the outer spring acts on a step surface of the excircle of the pin body through the back gasket; the other end of the outer spring acts on the surface of an element through the front gasket; the positioning end of the pin body is provided with an installing hole of the steel ball; and the outside of the installing hole closes up. The ball type unidirectional spring compressing positioning pin utilizes a structure that the steel ball is positioned at the positioning end, is enabled to realize unidirectionally positioning elements, and can realize compressing the elements without requiring screwing long-distance threads.
Description
Technical field
The utility model belongs to the aircraft rigger packing technique, relates to a kind of ball type 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, because the compressing member of design major part adopts the location compressing structure of holding down bolt and nut now, compress or release process in need to rotate very long distance screw thread 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.
Summary of the invention
The novel purpose of this reality be propose a kind of can quick mounting, the ball type unidirectional spring of few power that saves time compresses locating stud.Technical solution of the present utility model is that locating stud is made up of steel ball, limiting stopper, push rod, outer spring, inner spring, shank, pressure handle; Limiting stopper has screw thread to be installed in an end of push rod, and the other end screw thread of push rod is installed pressure handle, and inner spring is socketed on the push rod; The endoporus of shank is a step hole, inner spring acts in the step hole, outer spring is socketed on the cylindrical of shank, one end of outer spring acts on the step surface of shank cylindrical by packing ring, the other end of outer spring acts on the part plane by another packing ring, the positioning end of shank has the mounting hole of a steel ball, closes up in the outside of mounting hole.
Advantage that the utlity model has and beneficial effect, the utility model adopts the structure of ball in the positioning end location, 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 the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.Locating stud is made up of steel ball 1, limiting stopper 2, push rod 3, outer spring 4, inner spring 7, shank 6, pressure handle 8; Limiting stopper 2 has screw thread to be installed in an end of push rod 3, and the other end screw thread of push rod 3 is installed pressure handle 8, and inner spring 7 is socketed on the push rod 3; The endoporus of shank 6 is a step hole, inner spring 7 acts in the step hole, outer spring 4 is socketed on the cylindrical of shank 6, one end of outer spring 4 acts on the step surface of shank 6 cylindricals by back packing ring 5, the other end of outer spring 4 acts on the part plane by preceding packing ring 9, the positioning end of shank 6 has the mounting hole 10 of a steel ball 1, closes up in the outside of mounting hole 10.
Using method of the present utility model is: when the location compresses part, get locating stud, push pressure handle 8, push rod 3 travels forward, ball 1 falls, shank 6 is injected in the tool locating hole, unclamp pressure handle 8, push rod 3 moves backward, ball 1 rises, outer spring 4 compresses part, and ball 1 spacing shank 6 retreats, and makes shank 6 play the effect of location tension.Reverse operating when withdrawing from location shank 6 realizes that the taking-up of part is pulled down.
