Abstract
Nut provided by the invention guarantees load test tooling, belongs to nut machinery performance technologies field, mainly solves the problems, such as to thread off when nut test and stuck is difficult to separate on plug.Including split type transition sleeve and plug, the split type transition sleeve, it is made of at least three parts, its each section is altogether in a tubular form, its main feature is that: split type transition sleeve external cylindrical surface is provided with screw thread, it can be matched with subject nut, inner cylinder face is machined with T-type screw thread, can match with the T-type end of thread of plug；Split type transition sleeve includes split type transition sleeve one, split type transition sleeve two and split type transition sleeve three；When test, encounter subject nut tripping and stuck in the case where split type transition sleeve, first screw out the plug with the cooperation of split type transition sleeve, split type transition sleeve one is taken out out of subject nut afterwards, split type transition sleeve two and split type transition sleeve three are further taken out, to realize the separation of subject nut and tooling.
Description
Technical field
The invention belongs to nut machinery performance technologies fields, and in particular to nut guarantees load test tooling.
Background technique
Existing nut guarantees that load test is to apply axial tension to bolt using plug.When nut is met the requirements of the standard
When, the nut after test can be screwed out from plug with hand.When nut does not meet standard requirements, nut will thread off and it is stuck
On plug.There is defects for this method by plug application axial tension, i.e., since nut does not meet standard requirements, cause
Nut is stuck on plug, needs to cut off the rod head containing nut or destroys nut.Repeatedly excision plug will lead to
Plug is scrapped, and is destroyed nut and is needed to buy special equipment, can all generate waste using both methods.
Summary of the invention
The present invention is to solve when nut does not meet standard requirements, and nut will thread off and the stuck problem on plug, is mentioned
Guarantee load test tooling for a kind of nut using split type transition sleeve.
The present invention in order to solve the problems existing in the prior art, is adopted the technical scheme that:
Nut guarantees load test tooling, including split type transition sleeve and plug, the split type transition sleeve, by least
Three parts are constituted, each section altogether in a tubular form, its main feature is that: split type transition sleeve external cylindrical surface is provided with screw thread, can be with
It is matched with subject nut, inner cylinder face is machined with T-type screw thread, can match with the T-type end of thread of plug；Split type transition
Set includes split type transition sleeve one, split type transition sleeve two and split type transition sleeve three；Before test, split type transition sleeve is mounted in
Then the T-type end of thread of plug will be tested nut rotation set on the split type transition sleeve, be tested；The plug is fixed,
Fixture applies pulling force to subject nut, when encountering subject nut tripping and stuck in the case where split type transition sleeve, first screws out
With split type transition sleeve cooperation plug 4, after by split type transition sleeve one from subject nut in take out, further take out split type transition
Set two and split type transition sleeve three, to realize the separation of subject nut and tooling.
Compared with the prior art, the present invention has the following beneficial effects:
The present invention utilizes split type transition sleeve and plug, avoids due to nut tripping and stuck needs to cut off on plug
Rod head destroys nut and leads to the case where scrapping and purchase the special equipment for destroying nut of plug.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is cross-sectional view of the present invention；
Fig. 3 is the split type transition engaging body schematic diagram of the present invention；
Fig. 4 is plug schematic diagram of the invention.
In figure: 1-fixture；2-subject nuts；3-split type transition sleeves；The split type transition sleeve one of 3-1-；3-2-points
Body formula transition sleeve two；The split type transition sleeve three of 3-3-；4-plugs.
Specific embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4, nut guarantees load test tooling, including split type transition sleeve 3 and plug
4, the split type transition sleeve 3 is made of at least three parts, each section altogether in a tubular form, its main feature is that: split type transition
It covers 3 external cylindrical surfaces and is provided with screw thread, can be matched with subject nut 2, inner cylinder face is machined with T-type screw thread, can be with plug 4
The T-type end of thread match；Split type transition sleeve 3 includes split type one 3-1 of transition sleeve, two 3-2 of split type transition sleeve and fission
Three 3-3 of formula transition sleeve；Before test, split type transition sleeve 3 is mounted in the T-type end of thread of plug 4, then will be tested 2 rotation set of nut
On the split type transition sleeve 3, tested；The plug 4 is fixed, and fixture 1 applies pulling force to subject nut 2, when encountering
It is tested the tripping of nut 2 and stuck in the case where split type transition sleeve 3, the plug 4 of first back-out and the cooperation of split type transition sleeve 3,
Split type one 3-1 of transition sleeve is taken out out of subject nut 2 afterwards, further takes out split type two 3-2 of transition sleeve and split type transition sleeve
Three 3-3, to realize the separation of subject nut 2 and tooling.
Use process:
It is tested according to standard requirements according to Fig. 1 arrangement tooling.When encounter subject nut 2 tripping and it is stuck split type
When the case where transition sleeve 3, screw out with split type transition sleeve 3 cooperation plug 4, after by split type one 3-1 of transition sleeve from subject spiral shell
It is taken out in mother 2, further takes out three 3-3 of split type two 3-2 of transition sleeve and split type transition sleeve, to realize subject nut 2 and work
The separation of dress.
