Detailed description of the invention
Fig. 1 is the structural schematic diagram that the embodiment of the present application determines torsion screw.
Fig. 2 is the torque protection section disconnection schematic diagram that the embodiment of the present application determines torsion screw.
Specific embodiment
It is described in further detail with reference to the accompanying drawing and by embodiment to the application, following embodiment is to this Shen
Explanation please and the application is not limited to following embodiment.
The application design principle is to design the protection driving portion 1 for determining torsion in screw tail portion, when mounted equipment pair
Screw is tightened using protection driving portion when torsion is more sensitive, so that torsion is greater than the set value or protection is driven when set interval
Dynamic portion 1 disconnects, and prevention further tightens movement, prevents equipment damage.
The protection driving portion 1 include torsion control screw terminal 2, torque protection section 3, wherein torsion control screw terminal 2 with
Tightening tool (head) is used to transmit torsion with merging, when torsion is greater than the set value or torque protection section 3 disconnects when set interval,
To realize torque protection function.
Referring to FIG. 1 to FIG. 2, the embodiment of the present application, which determines torsion screw, to have torsion control screw terminal 2, torque protection section 3, tears open
Unload screw terminal 4 and spiro rod section 5.
The torsion control screw terminal 2 includes the hexagon socket head cap screw driver slot of 21 upper end of cone body 21 and cone body
22.Using cone body structure benefit and the reason is that, cone body 21 can effectively concentrate on stress in structure
In torque protection section 3, torque when torque protection section 3 is twisted off can be timely responded to and embody to guarantee torque protection section 3 with this,
Protect capital equipment.
The torque protection section 3 is the thinner cylindrical body of diameter, adjusts diameter as needed, sets so that torsion reaches
Definite value just will disconnect.
The application determine the design method of torsion screw the following steps are included:
S1: it determines screw material and to be protected need to twist off torque；
S2: torsion control screw terminal form parameter (21 taper of finger-type main body, torsion control 2 maximum gauge of screw terminal, taper are determined
At least two in 21 height of main body, another parameter can come out according to other two parameters and torque protection section diameter calculation)
With torque protection segment length；
S3: manufacture determines torsion screw with different-diameter torque protection section accordingly, every kind of diameter manufacture several (such as 3
~5) determine torsion screw；
Several of S4: every kind diameter torque protection section determine torsion screw and carry out twisting off test, averagely twisted off torque or
Maximum twists off torque as the torque protection setting value for determining torsion screw of the diameter torque protection section (if necessary to torque protection
Set interval, the then minimum torque~maximum value that twists off that several same diameters determine torsion screw can be used as torque protection and set
Determine section)；
S5: it is carried out curve fitting, is turned round according to the prior art according to the torque protection setting value of every kind of diameter torque protection section
It tries hard to keep and protects the corresponding relationship curve of section diameter Yu torque protection setting value, can be calculated according to this corresponding relationship curve various
The corresponding torque protection section diameter of torque is twisted off, to complete to determine the design of torsion screw.
Following table is the application part specific example data, and wherein 3 length of torque protection section is arranged in 2mm, cone body 21
Taper controls 2 maximum gauge of screw terminal and cone body 21 according to torsion and highly determines, it is small that torsion controls 2 maximum gauge of screw terminal
In being equal to disassembly 4 cross section regular polygon outside diameter of screw terminal, convenient for being screwed into fixation hole, usual 21 taper of cone body is 20
Between~60 degree, 21 taper of cone body uses 45 degree in following instance, and height (upper and lower distance) is 5mm, diameter (torque protection
Section) unit millimeter, torque protection setting value unit is kgf ﹒ cm.
It is described disassembly screw terminal 4 include outer-hexagonal shape disassembly main body 41 and be set to disassembly 41 upper end of main body safety it is recessed
Slot 42, safety groove 42 are connected with torque protection section 3.After torque protection section 3 is twisted off, torque protection section remains 31(and turns round
Have no progeny and stay in the part in safety groove 42) lower than plane in safety groove 42, so that torque protection section residual 31 will not hurt
Evil operator.
The application when it is implemented, by twisting off torque requirement and used screw grade actual conditions, according to upper table or
Person's above method actual measurement data is obtained twisting off torque and 3 diameter Relationship of torque protection section with existing curve-fitting method
(equation), to facilitate design torque protection section 3.
The spiro rod section 5 includes determining torsion screw to extend the body of rod and several silks being formed in outside the body of rod (to head) downwards
Tooth.
In the application determine torsion screw have protection fastening apparatus, operator is required it is low, to screwing tool performance
It is required that low feature.Stress effect is made full use of, torque protection section will be broken when torsion is excessive.So that anyone uses often
The fastening of rule tool will not damage institute's fastening apparatus, effectively solve existing screw because caused by torsion is excessive equipment it is impaired
Situation.Cost is reprocessed to save artificial and equipment, improves assembly efficiency.
The simple deformation or combination of all present techniques features and technical solution, it is considered that fall into the protection of the application
Range.
