By adopting the testing machine, load test and permanent deformation test of a belleville spring can be conducted conveniently; moreover, the load testing machine has the characteristics of simple structure, simplicity and convenience in operation, high efficiency, good universality, and reduction of labor intensity.
Description
Technical field
The utility model relates to a kind of test apparatus, particularly a kind of test apparatus that is used for the detection of disk spring load.
Background technology
Disk spring has and cushions damping capaicty preferably with respect to the spring of other types, and range of application more and more widely.According to the relevant criterion requirement, disk spring need carry out load-characteristic test and scrag test.But the equipment and the method that detect disk spring at present are all relatively backward, operate also more loaded down with trivial detailsly, and accuracy of detection and detection efficiency are not high, and checkout equipment does not catch up with the development need of disk spring.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provide a kind of simple in structure, measuring accuracy is high, the disk spring load test machine of good reliability.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of disk spring load test machine, it comprises a frame, described frame bottom is provided with a sensor array, platen is equipped with in the sensor array top, be provided with platen on directly over the platen under described, the described platen of going up is connected with a gear train moving up and down, and described gear train is provided with can measure the described sensor of going up the platen height change, and described sensor, gear train, sensor array are connected with a control system.
Preferably, described gear train comprises ball screw, screw mandrel belt wheel and servomotor, described ball screw lower end is connected with the described platen of going up, described ball screw upper end is connected with described screw mandrel belt wheel, described screw mandrel belt wheel is connected with described servomotor by being with synchronously, described sensor is a scrambler, and described scrambler is connected with described screw mandrel belt wheel, and described servomotor is connected with described control system.
Preferably, described ball screw outside is with the axis of guide.
Preferably, described sensor array is made up of with contour being installed on the sensor positioning disk of the form of equilateral triangle 3 pressure transducers, and described each sensor all is connected with described control system.
Preferably, described control system comprises the signal gathering unit of a pick-up transducers array and encoder feedback signal, and the control output unit and of the described servomotor of a control shows the display unit of output of pick-up transducers array and disk spring free height.
Technique scheme has following beneficial effect: this disk spring load test machine in use, disk spring is placed on down on the platen, during the test beginning, control system control servomotor drives the screw mandrel belt wheel and drives the ball screw lifting, by the last platen that is connected on the ball screw disk spring is added unloading.The pressure transducer that sensor array lists with the data transmission of gathering to control system, control system shows the data of receiving at display unit, and draw performance diagram automatically, and can gather the free height delta data of disk spring by scrambler, thus finish test.This tester has simple in structure, and is easy and simple to handle, the efficient height, and the characteristics of highly versatile have reduced labour intensity.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, this disk spring load test machine comprises a frame 1, and frame 1 bottom is provided with a sensor array 2, and 1 following platen 3 is equipped with in sensor array 2 tops, be provided with platen 4 on directly over the following platen 3, last platen 4 upper ends are connected with a gear train moving up and down.This gear train comprises ball screw 6, screw mandrel belt wheel 8 and servomotor 9.Last platen 4 upper ends are connected with the lower end of ball screw 6, ball screw 6 outsides are with the axis of guide 5, ball screw 6 tops are connected with screw mandrel belt wheel 8, and screw mandrel belt wheel 8 upper ends connect a scrambler 7, and scrambler 7 is used for detecting the height change of platen 4 as a sensor.Screw mandrel belt wheel 8 is connected with a servomotor 9 by being with synchronously, and servomotor 9 is fixed on the frame 1.
This disk spring load test machine in use, disk spring is placed on down on the platen 3, during the test beginning, control system control servomotor 9 drives screw mandrel belt wheel 8 and drives ball screw 6 liftings, adds unloading by the 4 pairs of disk springs of last platen that are connected on the ball screw 6.Sensor on the sensor array 2 with the data transmission of gathering to control system, control system shows the data of receiving at display unit, and draw performance diagram automatically, and can gather the free height delta data of disk spring by scrambler 7, thus finish test.
This tester can carry out load test and scrag test to disk spring very easily, have simple in structure, easy and simple to handle, the efficient height, the characteristics of highly versatile have reduced labour intensity.
More than a kind of automatic installation screw means that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
