Description

A kind of swivel nut auxiliary tightens tooling

Technical field

The utility model is related to mechanical dismounting fields, assist tightening tooling more particularly to a kind of swivel nut.

Background technology

Swivel nut be by a kind of high intensity, high-precision, the cold rolling diamond shape stainless steel wire Accurate Shaping of any surface finish helix Circle is the concentric body of high-precision internal and external screw thread, can form the screw thread of standard, and recoil inserts can form one after installing and meet the world The high-precision internal thread of standard, properties are superior to the screw thread of tapping formation.Existing make-up swivel nut tooling, since it is Torque is transmitted by the cooperation of " one " word groove on " one " the word convex block and swivel nut in tooling and tightens swivel nut, " one " word convex block and " one " word groove part is very narrow, cannot withstand larger torque or is easily deformed after bearing torque so that swivel nut and tooling All it is damaged, it is unreliable not also to be durable.Although the swivel nut in the prior art, also formed using screw rod, nut tears shape tool open, But for the tool when tightening swivel nut, nut directly squeezes swivel nut, during make-up, be easy to cause the damage of swivel nut.

The disclosure of background above technology contents is only used for design and the technical solution that auxiliary understands the utility model, not The prior art of present patent application is necessarily belonged to, shows the applying date of the above in present patent application in no tangible proof In the case of having disclosed, above-mentioned background technology should not be taken to the novelty and creativeness of evaluation the application.

Utility model content

The utility model aim is to propose that one kind is simple in structure, swivel nut will not be damaged in use auxiliary Help make-up tooling.

Preferably, the utility model can also have following technical characteristic：

A kind of swivel nut auxiliary tightens tooling, including cylinder guide, the first nut, further includes sleeve, a left side for the guide rod End offers the second segment external screw thread to match with the internal thread of swivel nut to be assembled；First nut is incorporated in the guide rod Portion, guide rod middle part offer the first segment external screw thread to match with first nut；The sleeve end face offers axial direction Through-hole, and mobilizable be set between the second segment external screw thread and the first nut.

Further, the guide rod right end is spanner incoming end.

Further, the spanner incoming end is interior hexagonal.

Further, the spanner incoming end is cylinder.

Further, the spanner access end side surface offers the through-hole through spanner end both sides.

Further, first nut is band shoulder nut.

Further, described sleeve one end is big, and one end is small, and big end is with first nut in the same side；The sleeve The opposite side of outer wall offers flat position, as clamping part.

Further, the second nut is further included, second nut is arranged between the sleeve and first nut.

Further, it is polished rod between the second segment external screw thread and first segment external screw thread.

The advantageous effect that the utility model is compared with the prior art includes：The utility model is by between nut and swivel nut Add sleeve, contacted using sleeve end face with swivel nut end face, increase the contact area of the two, effectively avoid stress concentration and damage This tooling and swivel nut；Spanner incoming end is outer-hexagonal or cylinder, and opens up through-hole in its side, in the feelings for the spanner not being suitble to Under condition, usable rod-shaped objects pierce into the through-hole, so as to pull guide rod, greatly enhance the practicability and versatility of this tooling； The opposite side of sleeve outer wall offers flat position, as clamping part, makes device simpler.

Description of the drawings

Specific embodiment

With reference to embodiment and compare attached drawing the utility model is described in further detail.It should be emphasized that It is that the description below is only exemplary rather than in order to limit the scope of the utility model and its application.

With reference to the following drawings, nonrestrictive and nonexcludability embodiment will be described, wherein identical reference numeral represents Identical component, unless stated otherwise.

A kind of swivel nut auxiliary as shown in Figure 1, 2 tightens tooling, including cylinder guide, the first nut 31, the first nut 31 be band shoulder nut, further includes sleeve 21, guide rod left end offers the second segment to match with the internal thread of swivel nut 11 to be assembled External screw thread 1, right end are the long square column 4 or interior hexagonal rotated for spanner.It is offered in the side of long square column 4 through its both sides Through-hole, in the case of the spanner not being suitble to, usable rod-shaped objects pierce into the through-hole, so as to pull guide rod, increase The practicability and versatility of this strong tooling.First nut 31 is incorporated in the middle part of guide rod, is offered and the first nut in the middle part of the guide rod The 31 first segment external screw threads 3 to match；The middle part of sleeve 21 is hollow, and sleeve 21 is mobilizable to be set in second segment external screw thread 1 and the Between one nut 31.Sleeve 21 is in the small structure in the big one end in one end, and big end is with the first nut 31 in the same side.In sleeve 21 Second nut 32 is set between the first nut 31.It is slided for convenience of sleeve 21, by second segment external screw thread 1 and first segment external screw thread Polished rod 2 is set as between 3.Escape is offered between polished rod 2 and first segment external screw thread 3.It, can be by making after swivel nut 11 is tightened The second nut 32 is fixed, then the first nut 31 is loosened with another spanner with spanner.

The application method of this technical solution：

1) swivel nut 11 is screwed in the first segment external screw thread 3 of guide rod left end；

2) it and then by the small end of sleeve 21, the second nut 32, the first nut 31 is put into guide rod from the right end of guide rod successively, And ensure swivel nut 11, sleeve 21, the second nut 32, the first nut 31 end face be in contact；

3) the first nut 31 is pulled with spanner again, swivel nut 11, sleeve 21, the second nut 32, the first nut 31 is made to force successively Tightly, and formed an interlinked mechanism, the position that most swivel nut 11 is specified in tightening into workpiece at last；

4) finally the first nut 31 is loosened, is then loosened the second nut 32, then use spanner with the second nut of spanner card column 32 The long square column 4 of clamping guide rod right end, reversely turns guide rod, and most tooling is separated from swivel nut 11 at last, completes to tighten swivel nut 11 work.

Flat position is offered in the opposite side of 21 outer wall of sleeve, it, in the case, only need to upper the as the clamping part of spanner One nut 31 can be achieved with carrying out swivel nut 11 upper next, and the first nut 31 is unclamped, and loosen the operation side of the first nut 31 Method is that the clamping part of sleeve outer wall is clamped with spanner, then loosens the first nut 31 with another spanner.

It would be recognized by those skilled in the art that it is possible that numerous accommodations are made to above description, so embodiment and attached Figure is intended merely to describe one or more particular implementations.

Although having been described above and describing the example embodiment for being counted as the utility model, those skilled in the art will be bright In vain, it can be variously modified and replaced, without departing from the spirit of the utility model.It is repaiied furthermore it is possible to make many Change the religious doctrine specific condition to be fitted to the utility model, without departing from the utility model central concept described here. So the utility model is not only restricted to specific embodiment disclosed here, but the utility model may further include and belong to this practicality All embodiments and its equivalent of novel range.
