Abstract

The utility model relates to a screw joint positioner proposed to provide a fixing member which can carry out fine adjustment and has a favorable combining positioning effect. The screw joint positioner comprises a base, a spring and a screw nut, wherein, the center of the base is provided with an equiangular polygon through hole of which both ends are provided with an annular upper and an annular lower female ends to form an equiangular polygon buffer space. The spring is a compression spring forming a central through hole. The outer surface of the screw nut corresponds to the equiangular polygon buffer space. The spring and the screw nut are contained in the buffer space of the base, and the top end of the spring and the bottom surface of the screw nut are respectively bunted and stuck with the upper and the lower female ends of the base.

Description

The bolted joints positioning work piece

The utility model belongs to fixed component, particularly a kind of bolted joints positioning work piece.

In industrial and commercial society now, people require strict day by day for article, its idea no longer rests in all right old thinking of thing, so have many businessman induct greatly the meaning difficulty do, former agricultural society can both accept through being combined into one, and simplicity fancy not, or the comparatively coarse product of processing procedure, shown in the 1st figure, be a kind of bolt 11 and screw 21 that depends on two interfacing parts 1,2.Bolt 11 is the center that is arranged at interfacing part 1 bottom surface, and screw 21 then is provided with the center of interfacing part 2 corresponding to bolt 11, uses to revolve the mode that lock is spirally connected, and interfacing part 1,2 is fixedly connected.But this structure usually can be because of the error in bolt 11 design, cause interfacing part 1,2 revolve lock be spirally connected urgent after, just find the neatly contraposition of corner of this interfacing part 1,2.If with the interfacing part neat contraposition in 1,2 corners, it is not tight to make interfacing part 1,2 be spirally connected again, and makes the mating face produce finedraw.Anyway revolving lock is spirally connected and all can't reaches specious effect.If buy the interfacing part 1,2 that is provided with pattern, decorative pattern or color, when just finding misalignment after assembling, this military order people is unhappy for it.

The purpose of this utility model provides and a kind ofly finely tunes, in conjunction with the bolted joints positioning work piece of good positioning effect.

The utility model comprises pedestal, spring and nut; The pedestal center is provided with the upper and lower inner stopper of two ends looping to form the equiangular polygon through hole of equiangular polygon buffer space; Spring is for constituting the pressure spring of central hole; The nut outer surface that is provided with the screw of boring a hole greater than spring center is corresponding with the equiangular polygon buffer space; Spring and nut are located in the buffer space of pedestal, and make spring top and nut bottom surface respectively to being affixed on the upper and lower inner stopper of pedestal.

Wherein:

Pedestal outer Monday of end surfaces edge ring is established circular fixed bolster.

Fixed bolster is provided with several can be for the fixed hole that revolves lock.

Fixed bolster is circular.

Nut one end surfaces edge system ring is established the heelpiece of equiangular polygon.

The sheathed spring of nut outer surface, and with its heelpiece supported spring bottom.

The nut outer surface is circular.

Because the utility model comprises pedestal, spring and nut; The pedestal center is provided with the upper and lower inner stopper of two ends looping to form the equiangular polygon through hole of equiangular polygon buffer space; Spring is for constituting the pressure spring of central hole; The nut outer surface is corresponding with the equiangular polygon buffer space; Spring and nut are located in the buffer space of pedestal, and make spring top and nut bottom surface respectively to being affixed on the upper and lower inner stopper of pedestal.When on the interfacing part of interfacing part that the utility model is applied to be respectively equipped with bolt and connecting hole, the utility model is flush-mounted in the connecting hole of interfacing part with its pedestal; The interfacing part bolt is revolved in the screw of locking nut, and be spirally connected mutually, when closely develop and its corner when still unjustified on the mating face of two interfacing parts, can be more a little the application of force revolve lock, the extrusion spring makes interfacing part that bolt and the utility model depend on respectively still can force turn screwing mutually when engaging, and it is fine-tuning to specific corresponding position, not only can finely tune, and in conjunction with good positioning effect, thereby reach the purpose of this utility model.

Fig. 7, be the utility model user mode combination schematic isometric.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As Fig. 2, shown in Figure 3, the utility model comprises pedestal 31, spring 32 and nut 33.

Pedestal 31 centers are provided with the upper and lower

inner stopper

312,31 3 of two ends looping to form the equiangular polygon through hole 311 of buffer space 314, pedestal 31 outer Monday of end surfaces edge ring is established circular fixed bolster 315, and be provided with several in fixed bolster 315 can be for the fixed hole 316 that revolves lock.

Spring 32 is for constituting the pressure spring of central hole 321.

Nut 33 is provided with screw 331, and the central through bore of its circular circumference and spring 32 321 is corresponding and wear, and one end surfaces edge system ring is established the heelpiece 332 of equiangular polygon.

Spring 32 is sheathed on nut 33 peripheries, and its bottom supports on nut 33 heelpieces 332; Spring 32 and nut 33 are located in the buffer space 314 of pedestal 31, and make spring 32 tops and nut 33 heelpieces 332 bottom surfaces respectively to being affixed on the upper and lower inner stopper 312,313 of pedestal 31.

As Fig. 4, shown in Figure 5, when the utility model being applied to be provided with the interfacing part 4 of bolt 41 and be provided with on the interfacing part 5 of connecting hole 52 of band reaming 51, the bolt 41 of interfacing part 4 and the utility model nut 33 screws 331 are corresponding and be spirally connected; The reaming 51 of interfacing part 5 and connecting hole 52 respectively with the utility model, pedestal 31 peripheries and fixed bolster 315 are corresponding and nested, in reaming 52 bottom surfaces be provided with pedestal 31 fixed bolsters 315 on fixed hole 316 corresponding screws 53.The utility model is flush-mounted in the connecting hole 52 and reaming 51 of interfacing part 5 with its pedestal 31 peripheries and fixed bolster 315, and the bolt 4 of fixed hole 316 screw locks in interfacing part 5 reamings 51 bottom surface screws 53 is spirally connected fixing on the fixed bolster 315 by passing.

As Fig. 6, shown in Figure 7, interfacing part 4 bolts 41 are revolved in the screw 331 of locking nut 33, and be spirally connected mutually, when interfacing part 4, when closely develop on 5 mating face, if interfacing part 4,5 corner is still unjustified, can be more a little the application of force revolve lock, make the nut 33 of the utility model inside be subjected to bolt 41 to revolve lock and rise, its heelpiece 332 also can rise and extrude spring 32 till tight, spring 32 also can produce reaction force and push heelpiece 332 downwards, make nut 33 very firm in pedestal 31, can dandle, relative interfacing part 4, therefore 5 also can be presented on us at the moment with the most perfect face of being spirally connected, the interfacing part 4 that bolt 41 and the utility model are depended on respectively, 5 still can force turn when screwing joint mutually, and fine-tuning to specific corresponding position, improve interfacing part 4,5 one engage the effect of location.

As mentioned above, the utlity model has following characteristics:

1, the buffer space 314 that constitutes by the utility model pedestal 31 can be revolved after locking compels for nut 33, also has the space of rising.

But 2, keep out nut 33 by spring 32 elastic support of the present utility model.

3, by the utility model the interfacing part with pattern, decorative pattern or corner is precisely alignd.

4, when screwing joint mutually, still can force turn by the model utility and the bolt 41 that depend on respectively on the interfacing part 5,4, and fine-tuning to specific corresponding position, improve the effect that interfacing part 4,5 one engage the location.
