Description
Technical field
The invention belongs to spring technical field of measurement and test, is related specifically to a kind of spring elongation flex life test device.
Background technology
Current spring test is all the compression and tension for concentrating on spring, but in practical service environment, may
There is the situation using spring bending elasticity, such as say the support member by the use of spring as a vibrating device, and the vibration fills
The vibration of the vibration, also horizontal direction that do not only have vertical direction is put, elastic force and longevity if only test spring vertical direction
Life, if ignoring the spring bending life-span, it is possible to cause the premature failure of vibrating device.It is therefore desirable to the spring bending life-span
Tested.
The content of the invention
The purpose of the present invention is to propose to a kind of spring elongation flex life test device, for testing the spring bending longevity
Life.
The spring elongation flex life test device of the present invention is made up of base and the support being fixed on base, the branch
Frame is disposed with arc disk and cross bar along the vertical direction, and the cross bar is provided with the first fixed part, first fixed part
On the central axis of arc disk；The arc disk is provided with arc-shaped slot, and the arc-shaped slot is provided with one can edge
The travel mechanism of groove movement, the travel mechanism are provided with the second fixed part；The base be installed with a motor and
One tensioning frame, the both ends of the tensioning frame are equipped with tensioning wheel, and motor shaft, tensioning wheel and the travel mechanism of the motor pass through
Rope connects, so that motor can drive travel mechanism, arcuately groove moves.
In test, the both ends of spring are utilized respectively the first fixed part, the second fixed part is fixed, then restart electricity
Machine, so as to drive travel mechanism and the second fixed part thereon, arcuately groove moves.Due to the movement locus of the second fixed part
It is arc, therefore during the second fixed part moves, spring will be to bend compressive state --- stretched vertically shape
State --- -- bending compressive state circulation, realizes the test in stretch bending life-span.
Further, the travel mechanism is made up of the main body through groove and the roller positioned at main body both ends, the master
Arc disk is sandwiched in wherein by the roller at body both ends.Roller can not only prevent travel mechanism from being come off from disk, can also subtract
Few resistance of motion between travel mechanism and groove.
Further, the distance between described arc disk and cross bar are adjustable, to adapt to the test of different height spring, separately
Outside, can also be by adjusting the distance between arc disk and cross bar, to cause spring to be in compression or extended state, test
It is more comprehensive.
Further, first fixed part, the second fixed part are hook formation.As long as by the first fixed part, second
Fixed part hooks spring end and can be achieved to fix, very convenient.
The stretch bending life-span that the spring elongation flex life test device of the present invention can be directed to spring is tested, and is mended
The deficiency of conventional springs test has been filled, there is good practicality.

Embodiment
Below against accompanying drawing, by the description to embodiment, for example involved to the embodiment of the present invention is each
Mutual alignment and annexation, the effect of each several part and operation principle between the shape of component, construction, each several part etc. are made into one
The detailed description of step.
Embodiment 1：
As shown in figure 1, the spring elongation flex life test device of the present embodiment is by base 1 and is fixed on base 1
Support 2 is formed, and the support 2 is disposed with arc disk 3 and cross bar 4 along the vertical direction, and it is solid that the cross bar 4 is provided with first
Determine portion 5, first fixed part 5 is located on the central axis of arc disk 3；The arc disk 3 is provided with arc-shaped slot, described
Arc-shaped slot is provided with a travel mechanism that can be moved along groove, and the travel mechanism is by the main body 7 through groove and positioned at master
The roller 8 at the both ends of body 7 is formed, and arc disk 3 is sandwiched in wherein by the roller 8 at the both ends of main body 7, in the main body 7 of travel mechanism
Provided with the second fixed part 9；The base 1 is installed with a motor 10 and a tensioning frame 11, and the two of the tensioning frame 11
End is equipped with tensioning wheel 12, and the axle of motor 10, tensioning wheel 12 and the travel mechanism of the motor 10 are connected by rope 6, so that
Travel mechanism's arcuately groove movement can be driven by obtaining motor 10.
The roller 8 of clamping disk 3 not only can prevent travel mechanism from being come off from disk 3, can also reduce travel mechanism
The resistance of motion between groove.
The distance between arc disk 3 and cross bar 4 are adjustable, to adapt to the test of different height spring, furthermore it is also possible to logical
The distance between arc disk 3 and cross bar 4 are overregulated, to cause spring to be in compression or extended state, test is more comprehensive.
Further, first fixed part 5, the second fixed part 9 are hook formation.As long as by the first fixed part 5,
Two fixed parts 9 hook spring end and can be achieved to fix, very convenient.
In test, the both ends of spring are utilized respectively the first fixed part 5, the second fixed part 9 is fixed, then restart electricity
Machine 10, arcuately groove back and forth moves the second fixed part 9 that the reciprocating rotation of motor 10 can by the drive travel mechanism of rope 6 and thereon
It is dynamic.Because the movement locus of the second fixed part 9 is arc, therefore during the second fixed part 9 moves, spring will be with
Bending compressive state, --- stretched vertically state --- -- bending compressive state circulation, realizes the test in stretch bending life-span.
