COIL SPRING MODELING APPARATUS

摘要

A coil spring modeling apparatus includes an actuator unit formed of a Stewart-platform-type parallel mechanism, a first inner load cell accommodated in a first attachment member, a second inner load cell accommodated in a second attachment member, and a rotation support mechanism. The actuator unit is rotatably supported by the rotation support mechanism about an axis. The first inner load cell is arranged on the first seat adapter coaxially with the rotation support mechanism, and detects an axial force acting on the lower spring seat and a moment. The second inner load cell is arranged under the second seat adapter coaxially with the rotation support mechanism, and detects an axial force acting on the upper spring seat and a moment.

主权项

1. A coil spring modeling apparatus provided on a strut comprising a first strut element and a second strut element which are movable relatively along an axis, the coil spring modeling apparatus comprising:
a lower spring seat provided on the first strut element; an upper spring seat arranged above the lower spring seat; a first attachment member disposed on the lower spring seat; a second attachment member disposed on the upper spring seat; a base member disposed above the upper spring seat; an actuator unit which is arranged between the first attachment member and the second attachment member, and extends and retracts; a rotation support mechanism which is arranged between the base member and the actuator unit, and configured to rotatably support the upper spring seat and the actuator unit with respect to the base member about the axis; a first inner load cell which is arranged coaxially with the rotation support mechanism within the first attachment member, comprises a through-hole into which the first strut element is inserted, and is configured to detect an axial force applied to the lower spring seat and a moment about the axis; and a second inner load cell which is arranged coaxially with the rotation support mechanism within the second attachment member, comprises a through-hole into which the second strut element is inserted, and is configured to detect an axial force applied to the upper spring seat and a moment about the axis.
