Abstract

The invention discloses a force actuator based on pulling and pressing spring sets, belongs to the technical field of precise mechanical apparatuses, and solves the problem that a mechanical force actuator in the prior art is low in force output precision. The force actuator comprises a housing, a motor, a mounting base, a fixing mechanism, a ballscrew, a nut, a force measuring element, an output shaft, a first spring bracing frame, a second spring bracing frame, a guiding axle set, a pressure spring set, an adjusting mechanism set and a pulling spring set, wherein the guiding axle set comprises n guiding axles, the pressure spring set comprises n pressure springs, the pressure springs and the guiding axles correspond to each other one by one, and the pressure springs sleeves the guiding axles. The two ends of each pressure spring contact respectively with the first spring cage and the second spring cage. The adjusting mechanism set comprises N adjusting mechanisms, the pulling spring set comprises N pulling springs, and the pulling springs and the adjusting mechanisms correspond to each other one by one. One end of each pulling spring is fixed on a second spring bracing frame, and the other end is fixed on the adjusting mechanisms. N is no smaller than three. The force actuator is high in output precision.

Description

technical field [0001] The invention belongs to the technical field of precision mechanical devices, and in particular relates to a force actuator based on a tension-compression spring group, which is suitable for the requirement of active optics on mirror support force control. Background technique [0002] Force actuators have a wide range of applications in many fields, especially in the field of optics. Active optics uses force actuators to output different support forces to the optical mirror to keep the mirror surface in a good state and ensure the imaging quality of the optical system. The current force actuators are mainly mechanical and pneumatic. Among them, the mechanical force actuator has low cost and simple control, and has become the mainstream of application. For example, the Chinese patent bidirectional linear precision force booster (publication number 101276051A) discloses a mechanical force actuator, which uses two sets of compression springs to convert ...
