Description
Technical field
It is more particularly to a kind of to twist de- frock the present invention relates to detection device technical field.
Background technology
The mechanical joining methods of fastener are largely used in machinery industry, fastener nut needs to survey in performance test
Try it and twist de- performance, to judge that its symbol does not meet requirement, there is presently no the de- performance of twisting for fastener nut to survey
The frock of examination.
The content of the invention
Based on the deficiencies of the prior art, it is an object of the invention to provide one kind to twist de- frock, can quick and precisely complete to twist
De- test.
To achieve the above object, the technical scheme is that：
One kind twists de- frock, it is characterised in that：Including backing plate, fixed plate, Shoulder Bushing, test nut, bolt and test
Equipment connector；The backing plate, fixed plate and Shoulder Bushing contain centre bore, and described test equipment connector one end is provided with
Square hole, the fixed plate both sides are provided with right angle double-fold, and the fixed plate is arranged on the top of the backing plate, the band shoulder
Bushing is arranged on the top of the fixed plate, and the Shoulder Bushing includes liner body, is separately positioned on the liner body two
The left shoulder and right shoulder of side, left shoulder and right shoulder are blocked by the right angle double-fold of the fixed plate both sides respectively, form " returning " font card
Connection structure is connect, the nut is arranged on the top of the Shoulder Bushing, and the bolt passes through the backing plate, the fixation
The centre bore of plate and the Shoulder Bushing is connected with the nut thread；The nut of the bolt is arranged on test equipment connector
Square hole in, be connected by the square hole with the test equipment connector.
Further, the liner body is trapezoidal.
Further, the liner body, left shoulder and right shoulder are integrally formed.
Beneficial effects of the present invention are：Twisting de- frock can quick and precisely complete to twist de- test, simple in structure, convenient disassembly.
Brief description of the drawings
Fig. 1 is the structure diagram of the specific embodiment of the invention；
Fig. 2 is the exploded view of the specific embodiment of the invention；
Fig. 3 is the profile of the specific embodiment of the invention.
Embodiment
The technique effect of design of the invention, concrete structure and generation is carried out below with reference to schematic diagram clear, complete
Ground describes, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is the one of the present invention
Section Example, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art is not paying creativeness
The other embodiment obtained on the premise of work, belongs to the scope of protection of the invention.
As shown in Figs. 1-3, it is a kind of to twist de- frock, including backing plate 1, fixed plate 2, Shoulder Bushing 3, test nut 4, bolt 5
With test equipment connector 6；The backing plate 1, fixed plate 2 and Shoulder Bushing 3 contain centre bore, their respective centre bores with
The diameter of bolt matches, and described 6 one end of test equipment connector is provided with square hole 61, and 2 both sides of fixed plate are provided with
Right angle double-fold 21, the fixed plate 2 are arranged on the top of the backing plate 1, and the Shoulder Bushing 3 is arranged on the fixed plate 2
Top, the Shoulder Bushing 3 include liner body 31, be separately positioned on 31 both sides of liner body left shoulder 32 and right shoulder
33, the present embodiment liner body 31, left shoulder 32 and right shoulder 33 are integrally formed, and liner body 31 is trapezium structure, and both sides are set
There are fabrication hole, convenient dismounting, left shoulder 32 and right shoulder 33 are blocked by the right angle double-fold 21 of 2 both sides of fixed plate, formed respectively
" returning " font clamping connecting structure, the test nut 4 is arranged on the top of the Shoulder Bushing 3, and the bolt 5 passes through
The centre bore of the backing plate 1, the fixed plate 2 and the Shoulder Bushing 3 is threadedly coupled with the test nut 4, tests nut
Shape be not limited to six sides, all kinds of abnormity nuts can be included；The nut of the bolt 5 is arranged on the square of test equipment connector
In hole 61, it is connected by the square hole 61 with the test equipment connector 6, the build-up tolerance control of square hole 61 and bolt head
System is between -0.01~0.08, it is ensured that the concentricity when rotating, it for the de- performance of twisting of test nut is its matching that bolt, which is,
Experiment plug, its bar portion has a screw thread, and when test is connected with nut thread.
The test method of this frock is：After tested nut is completed assembling according to above-mentioned assembly relation, start and test
The torsion testing machine of equipment connector one end connection.Torsion testing machine rotation axis will drive connector to rotate, so as to drive bolt
Rotate, occur slipping or when screw thread is cracked when turning to bolts and nuts, stop operating, measure the maximum torsion of the process
Force value is that the nut twists de- value.
It should be noted that described above is presently preferred embodiments of the present invention, the invention is not limited in above-mentioned
Embodiment, as long as it reaches the technique effect of the present invention with identical means, should all belong to protection scope of the present invention.
