Technical field
The utility model is related to detection device technical fields, more particularly to a kind of to twist de- tooling.
Background technology
The mechanical joining methods of fastener, fastener nut are largely used to need to survey in performance test in machinery industry
It tries it and twists de- performance, to judge that its symbol does not meet requirement, there is presently no the de- performances of twisting for fastener nut to survey
The tooling of examination.
Utility model content
Based on the deficiencies of the prior art, the purpose of this utility model is to provide one kind twisting de- tooling, can be quick and precisely complete
Test is taken off at twisting.
To achieve the above object, the technical solution of the utility model is：
One kind twisting de- tooling, 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 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 in the top of the backing plate, the band shoulder
Lining is set 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 at 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 connect with the nut thread；The nut of the bolt is arranged in test equipment connector
Square hole in, connect with the test equipment connector by the square hole.
Further, the liner body is trapezoidal.
Further, the liner body, left shoulder and right shoulder are integrally formed.
The beneficial effects of the utility model are：Twisting de- tooling can quick and precisely complete to twist de- test, simple in structure, dismounting side
Just.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model specific embodiment；
Fig. 2 is the exploded view of the utility model specific embodiment；
Fig. 3 is the sectional view of the utility model specific embodiment.
Specific implementation mode
Below with reference to schematic diagram to the technique effect of the design of the utility model, concrete structure and generation carry out it is clear,
It is fully described by, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment is this
A part of the embodiment of utility model, rather than whole embodiments are based on the embodiments of the present invention, those skilled in the art
The other embodiment that member is obtained without creative efforts belongs to the range of the utility model protection.
As shown in Figs. 1-3, a kind of to twist de- tooling, 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 the fixed plate are provided with
Right angle double-fold 21, the fixed plate 2 are arranged in the top of the backing plate 1, and the Shoulder Bushing 3 is arranged in the fixed plate 2
Top, the Shoulder Bushing 3 include liner body 31, be separately positioned on 31 both sides of the 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, both sides setting
There is fabrication hole, easy to disassemble, left shoulder 32 and right shoulder 33 are blocked by the right angle double-fold 21 of 2 both sides of the fixed plate respectively, are formed
" returning " font clamping connecting structure, the test nut 4 is arranged at 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, may include all kinds of abnormity nuts；The nut of the bolt 5 is arranged in the rectangular of test equipment connector
In hole 61, it is connect with the test equipment connector 6 by the square hole 61, 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 in rotation, it is that it is matched that bolt, which is for the de- performance of twisting of test nut,
Experiment plug, bar portion has a screw thread, and when test connect with nut thread.
The test method of this tooling is：After tested nut is completed assembly according to above-mentioned assembly relation, starts and test
The torsion testing machine of equipment connector one end connection.Torsion testing machine rotation axis will drive connector rotation, to drive bolt
Rotation occurs slipping or when screw thread is cracked, stops operating, measures the maximum of the process and turn round when turning to bolts and nuts
Force value is that the nut twists de- value.
It is the preferred embodiment of the utility model it should be noted that described above, the utility model not office
It is limited to the above embodiment, as long as it reaches the technique effect of the utility model with identical means, it is new should all belongs to this practicality
The protection domain of type.
