Abstract
The utility model discloses a double end stud screwing and extracting device, which belongs to the field of assembly tools for studs. The double end stud screwing and extracting device disclosed by the utility model comprises a double end stud, wherein one end of the double end stud is in threaded connection with a threaded sleeve; and the double end stud can be screwed or extracted by controlling the threaded sleeve. The double end stud screwing and extracting device has a simple structure, is easy and convenient to operate, is efficient for using, and is convenient and reliable; the problems of screwing of the double end stud into a threaded hole and extraction of the double end stud out of the threaded hole according to a required torque are solved; and cost is low, maintenance is simple and convenient, and popularization is facilitated.
Description
Technical field
The utility model relates to a kind of assembly tool that is used for double-screw bolt, particularly a kind of assembly tool that is used for studs.
Background technology
In process of production, often use studs, but tightening and taking out of studs is a bigger difficult problem, particularly required moment of torsion to be screwed in the screw and in the screw to studs and taken out, just a great problem especially.
Studs is in the past tightened and is taken out and often adopts two kinds of schemes: 1. with two nuts an end of studs carry on the back each other tight after; Tighten and take out studs through nut with six side's fork spanners again, the maximum problem of this scheme be the power of twisting too big nut can spin.2. be screwed in an end of double-screw bolt with a nut; Be pressed between double-screw bolt termination and nut with the end cap of little stay bolt again a band internal square hole; Come the Rotating Double header stud with protruding cubic spanner, also there is complex structure, operation shortcoming not too easily in this scheme, and the moment of torsion that transmits simultaneously is also limited.
In sum, existing method for realize studs on request moment of torsion be screwed in the screw and from screw and take out, all inapplicable, need a kind of new device or method to replace traditional technology.
The utility model content
The goal of the invention of the utility model is: the problem to above-mentioned existence, provide a kind of simple in structure, easy and simple to handle, and use efficiently, convenient and reliable studs is tightened withdrawing device.
The technical scheme that the utility model adopts is following:
The studs of the utility model is tightened withdrawing device, comprises studs, and the threaded one end of said studs connects swivel nut, can make studs tighten or take out through the control swivel nut.
Owing to adopted said structure, through being connected between studs and the swivel nut, make annexation surely lean on, guarantee safety in use.The studs of the utility model is tightened withdrawing device, in use with an end of swivel nut screwing in double-ended stud, and housing screw; Directly the rotation tubular nut just can carry out being screwed into of studs and back-out; Operation is simple for it, and with low cost, is beneficial to and applies.
The studs of the utility model is tightened withdrawing device, is provided with screw at the top of said swivel nut, and said screw can pass the top of swivel nut and an end of studs is conflicted.
Owing to adopted said structure; At the top of swivel nut through an end of screw conflict studs, thereby make between the end of swivel nut and studs be threaded more tight, thereby can use bigger moment to drive the studs rotation; Realization studs moment of torsion is screwed in the screw and from screw and takes out; And its mechanism is simple, and is easy and simple to handle, safe and reliable.
The studs of the utility model is tightened withdrawing device, and said swivel nut is set with conversion sleeve outward, adopt dismountable mode to be connected between said swivel nut and the conversion sleeve, and said conversion sleeve can cooperate with torque wrench.
Owing to adopted said structure, swivel nut is used conversion sleeve, just can make to tighten studs with torque wrench; Thereby reach preset moment of torsion, and adopt dismountable mode to be connected between swivel nut and the conversion sleeve, guarantee that its assembling and dismounting are very easy; Be convenient to change and use, reduce maintenance cost.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
1. the studs of the utility model is tightened withdrawing device, and is simple in structure, easy and simple to handle, uses efficient, convenient and reliable;
2. the studs of the utility model is tightened withdrawing device, has solved the studs moment of torsion difficult problem that is screwed in the screw and from screw, takes out on request, and with low cost, keeps in repair easyly, is beneficial to popularization.
Description of drawings
Fig. 1 is the structural representation that the studs of the utility model is tightened withdrawing device;
Fig. 2 is the left view of Fig. 1.
Mark among the figure: 1-studs, 2-swivel nut, 3-conversion sleeve, 4-screw.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As depicted in figs. 1 and 2; The studs of the utility model is tightened withdrawing device, comprises studs 1, and the threaded one end of said studs 1 connects swivel nut 2; Said swivel nut 2 can adopt tubular nut to process, and can make studs 1 tighten or take out through control swivel nut 2.Be provided with screw 4 at the top of said swivel nut 2, said screw 4 can pass the top of swivel nut 2 and an end of studs 1 is conflicted.The dismountable mode of employing is connected between the said swivel nut 2 outer conversion sleeves 3 that are set with, said swivel nut 2 and conversion sleeve 3, and said conversion sleeve 3 can cooperate with torque wrench; Can make to tighten studs 1 with torque wrench; Thereby reach preset moment of torsion, and adopt dismountable mode to be connected between swivel nut 2 and the conversion sleeve 3, guarantee that its assembling and dismounting are very easy; Be convenient to change and use, reduce maintenance cost.
The studs of the utility model is tightened withdrawing device; With an end of swivel nut 2 screwing in double-ended stud 1, housing screw 4 directly rotates swivel nut 2 and just can carry out being screwed into of studs 1 and back-out during use; Cooperate conversion sleeve 3, just can make to tighten studs with torque wrench.
The studs of the utility model is tightened withdrawing device, and is simple in structure, easy and simple to handle, uses efficient, convenient and reliable; Solve the studs moment of torsion difficult problem that is screwed in the screw and from screw, takes out on request, and with low cost, keeped in repair easyly, be beneficial to popularization.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
