At the same time by doing axial fatigue test in the state of radial force.
Summary of the invention
In order to guarantee the damper accuracy that axial fatigue is tested in the state of by radial force, the utility model is provided
It is a kind of that the damper radial direction applied load device for carrying radial force and facilitating detection power size, the technology of use can be applied to damper
Scheme is as follows:
A kind of damper radial direction applied load device, which is characterized in that vertical in damper and testing machine including being respectively fixedly connected with
The clamping plate and gripping sleeve of column, the thrust screw rod between clamping plate and gripping sleeve, the thrust screw rod pass through respectively connected unit and
Spring lock block is fixedly connected with clamping plate and gripping sleeve, and the thrust screw rod between connected unit and spring lock block is equipped with spring,
The thrust screw rod passes through spring inner and is coaxially distributed with spring, and the both ends of the spring has been respectively fixedly connected with the first spring pressure
Ring and second spring pressure ring, the first spring pressure ring and second spring pressure ring be coaxially distributed in thrust screw rod outer round surface and
It can be moved axially along thrust screw rod, the spring pressure ring close to damper side is also fixedly connected with adjusting nut, the adjusting spiral shell
It is female be threadedly coupled between thrust screw rod.
Preferably, force sensor is fixedly connected between the connected unit and clamping plate.
Preferably, the connected unit is the convex shape structure that middle part is equipped with through-hole, and the connected unit passes through hexagon thin nut
It is fixedly connected with thrust screw rod.
The utility model has the beneficial effects that:
1, the cooperation of adjusting nut and thrust screw rod, it may be convenient to which the size of adjustment spring power is suitable for different model
The test of damper；
2, pass through force snesor, it may be convenient to detect the size of radial thrust；
3, damper can be clamped by the present apparatus and spring pressure is effectively passed into damper, simulation damper exists
It receives and does axial fatigue test in the state of radial force, test result is more accurate.
