Worm Gear Displacement Actuator

Abstract

A worm and gear displacement actuator comprises a main device, a displacement actuating device and a corrugated pipe device. The main device comprises a box body, a supporting rod and a worm and gear device. The displacement actuating device comprises a transmission ball screw, a screw nut, a nut ejection rod and a steel ball. The corrugated pipe device comprises a corrugated pipe, a corrugated pipe flange, a first screw and a second screw. According to the worm and gear displacement actuator, high-precision positioning of a laser device can be ensured through the displacement actuating device, and meanwhile a movement member is sealed and protected by the corrugated pipe device so that pollution generated by a movement pair cannot leak or overflow to an optical component. Thus, the cleanliness of the optical component is guaranteed, and the load capacity of the whole device is improved.

Description

technical field [0001] The present invention relates to high power laser devices, especially worm gear displacement actuators. Background technique [0002] The high-power laser device is a laser device that provides extremely high temperature and pressure conditions for inertial confinement fusion and high-energy physics research, in which micro-displacement actuators are used to ensure the positioning and angle adjustment of the laser device. With the deepening of laser inertial confinement nuclear fusion research, it is necessary to ensure the precise positioning and angle adjustment of the device, and at the same time put forward higher requirements for the cleanliness of the actuator for adjusting the displacement. [0003] At present, most of the existing displacement actuators are of worm gear structure, that is, the worm gear is driven by the motor to output a certain adjustable displacement, but the adjustment positioning accuracy is average, which cannot meet the n...

Problems solved by technology

[0003] At present, most of the existing displacement actuators are of worm gear structure, that is, the worm gear is driven by the motor to output a certain adjustable displacement, but the adjustment positioning accuracy is average, which cannot meet the needs of more and more in-depth research, and the accuracy upgrade is very necessary. In addition, the organic pollution produced by the lubricating oil in the motion pair of the displacement actuator is an important source of pollution in the entire laser device. The pollutants deposited or adhered to the surface of the optical components are scattered when the high-energy laser passes through the surface of the components. Not only It may reduce the beam quality, and in severe cases, it may induce damage to components and reduce the service life of components. Therefore, strict cleaning control is necessary
