Problems solved by technology

[0003] The existing linear controllable drive devices mainly include linear motors. This kind of mechanism itself has a relatively complicated structure and low precision of displacement control. In particular, in the case of limited volume, it is often unable to provide a large driving force and cannot satisfy Modern industry's demand for micro precision drive control and positioning
[0004] At present, there is no description or report of the similar technology of the present invention, and no similar data at home and abroad have been collected yet.

Abstract

The invention provides a precision controllable linear driver comprising a base, a mover part and at least one drive member. The base is provided with a first cavity allowing relative movement of the mover part and a second cavity used for holding the drive members. The mover part comprises two outer end parts and a middle part; the outer end parts are detachably and rigidly connected with or integrated to the middle part; the mover part is made of permeability magnetic material; magnetic circuit structures in mutual action are formed between the drive members and the mover part. The invention further provides a combined precision controllable linear driver based on the precision controllable linear driver. The precision controllable linear driver and its combination are simple in structure and light in weight and meet the need of the modern industry for precision control drive equipment.

Description

technical field [0001] The invention relates to an active vibration control and force-controlled displacement device in the technical field of drives, in particular to a precision controllable linear drive device and a combination thereof. Background technique [0002] The precision controllable driving device is mainly used in the active control of vibration, in the device that bears a certain load driving force and has positioning requirements, and provides a certain driving force by controlling the movement of the mover components to achieve active control of vibration and realize positioning control. [0003] The existing linear controllable drive devices mainly include linear motors. This kind of mechanism itself has a relatively complicated structure and low displacement control accuracy. In particular, it is often unable to provide a large driving force and meet the requirements of the limited volume. Modern industry demands for miniature precision drive control and p...
