Embodiment
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
Spring anti-fatigue test equipment as shown in Figure 1, including temperature and humidity control box 1, in the temperature and humidity control box 1
Fixed plate 2 is provided with, multiple first spring fixed clamp tools 3, in addition to bogie 4, the driving are installed in the fixed plate 2
Be provided with frame 4 with the one-to-one second spring stationary fixture of the first spring perch, in addition to driving bogie 4 is towards fixation
The drive mechanism that plate 2 moves forward and backward, the bottom of fixed plate 2 are additionally provided with the bottom plate 5 being fixedly connected with fixed plate 2, the bottom
The bottom of plate 5 is provided with the vibration mechine 12 that driving bottom plate 5 vibrates, and the vibration mechine can be electrodynamic vibration shaker, electromagnetism
Formula shake table, hydraulic vibration generator and mechanical shaker etc., this vibration mechine can carry out horizontal vertical vibration simultaneously, and it shakes
Flowing mode can select fixed frequency, frequency sweep or random vibration mode, the first spring perch described above and second according to test requirements document
Spring perch can be by the securing diversified forms of spring one end, such as：The neck that spring one end clamping is lived, or by spring
What in the market can directly buy acquisition can be used to have humiture for the clip that one end is clamped, temperature and humidity control box 1 described above
The temperature and humidity control box 1 of regulatory function.
The operation principle of said mechanism is as described below：The spring for needing to be tested is fixed on the first corresponding spring
Between stationary fixture 3 and second spring stationary fixture, the humiture environment in temperature and humidity control box 1 is set, opens vibration test
Platform 12 causes bottom plate 5 to be in vibrational state, and then drive mechanism driving bogie 4 does straight reciprocating motion so that spring one
Directly it is in reciprocal compression stretching state, is taken out after the compression stretching of certain number, then by spring, observes the resistance to of spring
Spring can be individually positioned in different humitures, different vibration frequencies and different compressions by long property, mechanism when being tested
Durable test is carried out in the environment of number, so as to measure the durability of spring under various circumstances, due to the use environment of spring
Difference, such as：Southern and northern humiture difference, and for example：When spring is used to static equipment, spring is using process
In will not be in vibrational state, when spring is using on automobile, the moment is in vibrational state spring again, therefore different
Requirement and durability of the environment to spring are different, therefore this equipment can simulate spring practice environment to the resistance to of spring
Long property is detected, so as to improve the durability test precision of spring.
On the basis of the above, the drive mechanism can be cylinder, electric cylinders etc., and the drive mechanism that mechanism uses includes solid
The line slideway 6 of the both sides of bottom plate 5 is scheduled on, the bogie 4 is arranged on line slideway 6 by sliding block and can be along line slideway 6
Move forward and backward, the bottom of bogie 4 is provided with the ball screw 7 that driving bogie 4 moves forward and backward along line slideway 6, described
Ball screw 7 is connected with shaft coupling 8, in addition to the drive motor 9 connected with shaft coupling 8 away from the one end of fixed plate 2, is working
When, drive motor 9 drives ball screw 7 to rotate by shaft coupling 8, so as to drive bogie 4 to be moved forward and backward along line slideway 6,
Such a driving structure is simple in construction, and motion is accurate, so as to improve the precision of spring durability test.
On the basis of the above, through hole is provided with the temperature and humidity control box 1, the shaft coupling 8 is located at through hole so that
Drive motor 9 is located at outside Temperature Humidity Sensor, is additionally provided with outside the temperature and humidity control box 1 for supporting drive motor 9
Motor fixing base 10, such a structure is because drive motor 9 is located at outside temperature and humidity control box 1, due to high temperature, the ring of high humility
Border can cause drive motor 9 to break down, so as to be impacted to the service life of drive motor 9, so that testing
Cheng Zhong, the environmental factor in temperature and humidity control box 1 will not be impacted to drive motor 9 so that drive motor 9 can be transported normally
Turn.
On the basis of the above, in addition to the sealing ring that is arranged on outside shaft coupling 8, the setting of the sealing ring causes warm and humid
Moisture and heat or cold air in degree control cabinet 1 will not be lost in from through hole, so as to ensure the accuracy of ambient parameter.
On the basis of the above, in addition to the axis of guide 11 that is fixed in fixed plate 2, the axis of guide 11 pass through the first spring
Stationary fixture 3 and corresponding second spring stationary fixture, in test, spring to be tested is directly set in the axis of guide
On 11 so that when being compressed test, spring prevents spring in test with being compressed and stretching along the direction of the axis of guide 11
The situation for arching upward or arching upward downwards upwards occurs.
Particular embodiments described above, the purpose of this utility model, technical scheme and beneficial effect are carried out to enter one
Step describes in detail, should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
