The utility model discloses simple structure to can accomplish the tired experiment of two bearing springs simultaneously, experimental efficiency is high.
Description
Technical field
The utility model relates to the fatigue test device of bearing spring.
Background technology
Existing Patting type bearing spring fatigue test device comprises base, swing arm and swing arm driving mechanism.One end of swing arm is connected with base rotation by pivot, and swing arm driving mechanism swings up and down around described pivot for driving this swing arm, makes the other end of swing arm can pat bearing spring to be measured.The motor that this swing arm driving mechanism comprises bent axle, driving crank rotates and gear train, bent axle is connected with the other end of swing arm by this gear train.
Existing Patting type bearing spring fatigue test device can only test a bearing spring at every turn, and conventional efficient is not high.In addition, because swing arm driving mechanism will adopt the parts such as bent axle, gear train, structure is comparatively complicated, and cost is also higher.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of conventional efficient is high, structure simple Patting type bearing spring fatigue test device.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Patting type bearing spring fatigue test device, comprises base, walking beam, a pair spring positioning pedestal and hydraulic cylinder; The middle part of walking beam is connected with base rotation by pivot; The bottom surface that walking beam is positioned at pivot both sides is respectively equipped with a spring upper end circle location division; A pair spring positioning pedestal lays respectively at the below of two spring upper end circle location divisions, and the top of each spring positioning pedestal is provided with a lower spring end circle location division; Hydraulic cylinder is arranged on any side of pivot, and the piston rod of hydraulic cylinder is connected with walking beam.
The utility model at least has following technique effect:
1, the utility model is by being located at the middle part of walking beam by pivot, bearing spring to be tested is placed in respectively the both sides of pivot, can carry out fatigue experiment simultaneously, thus improve conventional efficient to two pieces bearing spring;
2, the utility model utilizes hydraulic cylinder as the power source driving walking beam to swing, and has abandoned the mechanical part that bent axle, gear train etc. are complicated, has reduced cost, and make one-piece construction simpler;
3, by changing the piston rod of hydraulic cylinder and the link position of walking beam, namely can realize compressing the bearing spring of different swing arm radius and the anti-fatigue of resilience is tested, having widened range of application of the present utility model.
Accompanying drawing explanation
Fig. 1 shows the structural representation of the Patting type bearing spring fatigue test device according to the utility model one embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Refer to Fig. 1.According to the Patting type bearing spring fatigue test device of the utility model one embodiment, comprise base 1, walking beam 2, a pair spring positioning pedestal 3 and hydraulic cylinder 4.
The middle part of walking beam 2 is rotationally connected by pivot 5 and base 1.The bottom surface that walking beam 2 is positioned at pivot 5 both sides is respectively equipped with a spring upper end circle location division 21.In the present embodiment, each spring upper end circle location division 21 can allow the upper end ring of bearing spring 6 form around convex platform thereon by one, and convex platform is connected with the bottom surface of walking beam 2.
A pair spring positioning pedestal 3 lays respectively at the below of two spring upper end circle location divisions 21, and the top of each spring positioning pedestal is provided with a lower spring end circle location division 31.In the present embodiment, each lower spring end circle location division 31 can allow the lower end turn of bearing spring 6 form around lower convex platform thereon by one.When the two pieces bearing spring identical for swing arm radius is tested, need to make two spring upper end circle location divisions 21 be located at the both sides of pivot 5 respectively with being mutually symmetrical.If the swing arm radius of two pieces bearing spring to be measured is different, then the distance between two spring upper end circle location divisions 21 and pivot 5 is set according to actual conditions.
Hydraulic cylinder 4 is arranged on any side of pivot 5, that is, hydraulic cylinder 4 both can be arranged on the left side of pivot 5, also can be arranged on the right side of pivot 5.The piston rod 41 of hydraulic cylinder 4 is connected with walking beam 2.Preferably, the piston rod 41 of hydraulic cylinder 4 is connected by the end face of universal joint 7 with walking beam 2, thus can reduce the impaired probability of hydraulic cylinder.In the present embodiment, hydraulic cylinder 4 is positioned at the top of walking beam 2; The cylinder body 42 of this hydraulic cylinder 4 is fixed in a hydraulic ram mounting bracket (not shown).Hydraulic cylinder 4 can select oil cylinder.
During work, the piston rod 41 of hydraulic control cylinder 4 stretches out continuously and retracts, and makes the bearing spring 6 of pivot 5 both sides of walking beam 2 realize Repeated Compression and resilience, thus completes the fatigue experiment of bearing spring.By the link position of the piston rod 41 with walking beam 2 that change hydraulic cylinder, namely can realize compressing the bearing spring of different swing arm radius and the anti-fatigue experiment of resilience, widen range of application of the present utility model.
