Embodiment
Below, with reference to accompanying drawing and embodiment the spring transverse vibration life test apparatus of the utility model is elaborated:
Shown in Fig. 1～3, a kind of spring transverse vibration life test apparatus comprises the motor 1 that is installed on the pedestal 2, and pedestal 2 is installed on the test-bed 9, and motor 1 is connected with rolling disc 4 through shaft coupling 3.On rolling disc 4, be respectively arranged with eccentric shoe 5, screw rod holder 7, screw rod 8, eccentric scale chi 18; Below the both sides of rolling disc 4, eccentric shoe 5, respectively form a T type groove (not shown); Eccentric shoe 5 is installed on the rolling disc 4 through bolt 19; Bolt 19 can move along the T type groove on the rolling disc 4, checks the eccentric position of eccentric shoe 5 with eccentric scale chi 18.
The lower end of vibrating arm 6 and eccentric shoe 5 are hinged, and the upper end of vibrating arm 6 and vibrating arm stationary shaft 17 are hinged, and vibrating arm stationary shaft 17 is fixed on the vibrating mass 16.Spring vibration plate 14 is installed on the vibrating mass 16 through spring vibration plate holder 15; Be respectively arranged with spring dead plate 13 in the both sides of spring vibration plate 14; Two spring dead plates 13 are installed in respectively on two spring suppports 11; Spring suppport 11 is installed on the support arm 12, and support arm 12 tops connect crossbeam 20.
On the edge of spring vibration plate 14 and spring dead plate 13, be formed with a plurality of through holes 21, in through hole 21, be mounted with a plurality of test springs 22.
The process of the test of the utility model is:
Unclamp the nut of the bolt 19 on the eccentric shoe 5, rotating screw bolt 8 on demand, regulate the position of eccentric shoe 5; Bolt 19 moves along T type groove with eccentric shoe 5, observes the scale of eccentric scale chi 18 simultaneously, when reaching required offset; With the nut screwing clamping on the bolt 19, can begin test again.
Motor 1 starts the back and drives rolling disc 4 rotations; Rolling disc 4 drives vibrating arm 6 through eccentric shoe 5 and moves up and down; Vibrating arm 6 drives vibrating mass 16 through vibrating arm stationary shaft 17 and slides up and down along support arm 12; Pump thereby drive spring vibration plate 14, finally make test spring 22 transverse vibration.
The utility model compact conformation, easy to operate, safety once can realize a plurality of spring transverse vibration durability tests simultaneously.
