For solving technical matters described in the utility model, the technical solution adopted in the utility model is:
The utility model is a kind of spring life test unit, described spring life test unit comprises hollow pins, central shaft, testing bed, testing stand, motor, described testing bed, testing stand sets out oval-shaped cavity, and the end of described central shaft in cavity sets out the runner of cylindrical diameter dimension greater than center shaft body, central shaft is connected with motor, and runner is provided with hollow pins on the side.
Its diameter of described runner and the less equal diameters of oval-shaped cavity size.
The both sides of the cavity of described testing bed, testing stand are provided with protecgulum pressing plate and back plate respectively.
Between the cavity of described testing bed, testing stand and the protecgulum pressing plate intermediate plate is set.
The oil sealing in sealing back plate and intermediate shaft gap is set on the back plate of described testing bed, testing stand.
Be connected by shaft coupling between described central shaft and the motor.
Described protecgulum pressing plate is connected by bolt with front shroud.
Described front shroud is a plastic material.
Adopt the beneficial effect of the technical solution of the utility model to be:
The centrifugal force that the utility model emphasis has utilized object to be produced in high-speed motion throws away spring, the centrifugal force that object is produced in high-speed motion is throwing away object, utilize the shape of inner chamber, make spring under action of centrifugal force, the process that throws away-compress-throw away-compress.
Structure of the present utility model, easy to use, can save a large amount of time than shuttle, can shorten the test period.Easy to operate, safety is easy to manufacture simultaneously.
