Abstract

The utility model discloses a steel-ball one-way nut compressing positioning pin, which belongs to airplane assembly tooling technology. The positioning pin comprises a steel ball, a limiting block, an ejecting rod, a knurled nut, a spring, a pin body and a pressing handle. The limiting block is installed at one end of the ejecting rod through threads, and the pressing handle is installed at the other end of the ejecting rod through threads; and the spring is sleeved on the ejecting rod. An inner hole of the pin body is a step hole; the spring acts in the step hole; the knurled nut is installed on the pin body through threads; a mounting hole of the steel ball is arranged at a positioning end of the pin body; and the outer side of the mounting hole is closed. In the utility model, the steel ball is adopted to position at the positioning end to lead the positioning pin to realize one-way positioning parts; parts compressing can be realized without needing rotating threads in long distance; the steel-ball one-way nut compressing positioning pin can be used in a closed structure, or can realize single operation for parts positioning in large-area tooling; the nut is compressed, the positioning is reliable, and the working efficiency is greatly increased.

Description

The ball type One-way nut compresses locating stud

Technical field

The utility model belongs to the aircraft rigger packing technique, relates to a kind of ball type 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, 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 One-way nut 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, knurled nut, spring, shank, pressure handle; The limiting stopper screw thread is installed in an end of push rod, and the other end screw thread of push rod is installed pressure handle, and spring housing is connected on the push rod; The endoporus of shank is a step hole, and spring action is in step hole, and knurled nut's screw thread is installed on the shank, and 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 steel 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.

Fig. 2 is the utility model work schematic 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, knurled nut 4, spring 5, shank 6, pressure handle 7; 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 7, and spring 5 is socketed on the push rod 3; The endoporus of shank 6 is a step hole, and spring 5 acts in the step hole, and knurled nut's 4 screw threads are installed on the shank 6, and the positioning end of shank 6 has the mounting hole 8 of a steel ball 1, closes up in the outside of mounting hole 8.

Using method of the present utility model is: when the location compresses part 9, get locating stud, push pressure handle 7, push rod 3 travels forward, steel ball 1 falls, and shank 6 is injected in tool locating part 10 positioning holes, unclamps pressure handle 7, push rod 3 moves backward, steel ball 1 rises, and tightens knurled nut 4, makes knurled nut 4 compress part, steel 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.(referring to shown in Figure 2)
