Utility model content
The technical problems to be solved in the utility model is: fix with upper mounting seat and lower mounting seat respectively to solve current air spring fatigue machine two ends of air spring in process of the test, cannot rotate, make the problem that result of the test accuracy is relatively low, it is provided that a kind of air spring life test machine.
This utility model solves its technical problem and be the technical scheme is that a kind of air spring life test machine, including test stand, pivoted arm and driving means, the top and bottom of described test stand are respectively provided with an a connecting seat, two paired linea angulatas of a connecting seat on test stand are arranged, described pivoted arm is arranged on the centre of test stand, the two ends of pivoted arm are provided with the second connection seat corresponding with a connecting seat, described a connecting seat and second connects seat and is respectively used to connect the two ends of air spring, the outfan of described driving means connects the middle part of pivoted arm, described driving means is externally provided with cabinet.The cylinder bottom of air spring connects seat and a connecting seat connects, piston rod and second connects seat and connects, driving means drives pivoted arm to rotate with pivoted arm center for initial point, pivoted arm drives the piston rod of air spring to move, the cylinder body of piston rod elongation and air spring tilts, this epidemic situation comparison, close to the real duty of air spring, makes result of the test more accurate.
Described driving means includes motor and gear reduction, described gear reduction includes intermeshing first gear and the second gear, described first gear is connected with the output shaft of motor, described second gear is partial gear, central angle between first teeth and last teeth of described second gear is α, 0 ° of < α < 90 °, described pivoted arm and the second gear connect.Driving motor to use asynchronous machine, start motor during test, make the first gear and the engagement of the second gear, the second gear driven pivoted arm rotates, the piston rod of stretching air spring, makes motor reversal, make air spring reset after having tested.During in order to prevent electrical fault, pivoted arm continues to rotate, and damages air spring, and when last teeth of the second gear leave the first gear, the second gear does not continues to rotate, so that pivoted arm stops operating, protects air spring.
In order to alleviate pivoted arm weight, reducing energy consumption, the cross section of described pivoted arm is I shape.
The beneficial effects of the utility model are, driving means of the present utility model drives pivoted arm to rotate with pivoted arm center for initial point, pivoted arm drives the piston rod of air spring to move, the cylinder body of piston rod elongation and air spring tilts, this epidemic situation comparison, close to the real duty of air spring, makes result of the test more accurate.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cabinet inside structural representation.
In figure: 1. test stand, 2. pivoted arm, 3. cabinet, 4. a connecting seat, 5. second connects seat, 6. the first gear, 7. the second gear.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
As shown in Figure 1, a kind of air spring life test machine, including test stand 1, pivoted arm 2 and driving means, the top and bottom of described test stand 1 are respectively provided with an a connecting seat 4, the paired linea angulata of two a connecting seat 4 on test stand 1 is arranged, described pivoted arm 2 is arranged on the centre of test stand 1, the two ends of pivoted arm 2 are provided with the second connection seat 5 corresponding with a connecting seat 4, described a connecting seat 4 and the second connection seat 5 are respectively used to connect the two ends of air spring, the outfan of described driving means connects the middle part of pivoted arm 2, and described driving means is externally provided with cabinet 3.In order to alleviate pivoted arm 2 weight, reducing energy consumption, the cross section of described pivoted arm 2 is I shape.It is hinged with a connecting seat 4 of test stand 1 upper end that the cylinder bottom of the first air spring connects seat, it is hinged that piston rod is connected seat 5 with on pivoted arm 2 the second of homonymy, it is hinged with a connecting seat 4 of test stand 1 lower end that the cylinder bottom of the second air spring connects seat, it is hinged that piston rod is connected seat 5 with on pivoted arm 2 the second of homonymy, driving means drives pivoted arm 2 to rotate with pivoted arm 2 center for initial point, pivoted arm 2 drives the piston rod of 2 air springs to move simultaneously, the piston rod elongation of air spring and the cylinder body of air spring tilt, this epidemic situation comparison is close to the real duty of air spring, make result of the test more accurate.
