Embodiment 1

[0060] In this embodiment, an electromagnetic adaptive clamping and clamping device includes: a clamping component, a first magnet, and a second magnet; a magnetic circuit structure is formed between the first magnet and the second magnet; When the force exerted by the magnetic field on the first magnet changes, the first magnet can move between the locking position and the loosening position;

[0061]When the first magnet moves from the loose position to the locked position, it drives the clamping part to perform a tightening action, so that the controlled object is locked in the clamp;

[0062] When the first magnet moves from the locked position to the relaxed position, it drives the clamping part to perform a stretching action, so that the controlled body can run freely;

[0063] When the first magnet moves between the loose position and the locked position, it drives the clamping part to perform a zooming action, so that the controlled body produces a variable damping cha...

Embodiment 2

[0077] Such as Figure 12 As shown, a combined clamping and clamping device according to the present invention includes an actuator, and also includes the electromagnetic self-adaptive clamping and clamping device; when the actuator is working, the two sides of the actuator are The clamping parts of the electromagnetic self-adaptive clamping and clamping device alternately perform tightening and stretching actions, so that the actuator drives the target body located on both sides of the actuator to form an inchworm movement, and the overall structure produces a motion displacement; wherein, The alternating cycle is the cycle of the actuator extending and contracting.

[0078] Specifically, the present invention provides a combined clamping and clamping device, which can realize the movement of inchworms through actuators. The combined clamping and clamping device may include multiple sets of the electromagnetic self-adaptive clamping and clamping device, and is configured wit...

Embodiment 3

[0080] Such as Figure 13 As shown, a combined clamping and clamping device according to the present invention includes a plurality of actuators and a plurality of electromagnetic adaptive clamping and clamping devices corresponding to the plurality of actuators; A plurality of electromagnetic adaptive clamping devices are all located on the same side of the corresponding actuator; when the actuator is stretched, the clamping parts of the electromagnetic adaptive clamping device perform a tightening action to drive the space The target body moves; when the actuator contracts, the clamping part of the electromagnetic self-adaptive clamping and clamping device performs a stretching action to release the space target body and keep the space target body still.

[0081] Specifically, the combined clamping and clamping device provided in this embodiment can carry out the transportation and transmission of the space object through an external actuator. The combined clamping and clam...

Abstract

The invention provides an electromagnetic adaptive clamp fastening device and a combined type clamp fastening device. A first magnet can be moved between a fastening position and a looseness position under the condition that the action force of the magnetic field generated by a second magnet which is applied on a first magnet is changed; and a clamp member is driven to execute the fastening and loosening actions when the first magnet is moved between the fastening position and the looseness position. The invention utilizes the electromagnetic permanent magnetism direct interaction to carry out driving and realize clamping and fastening, and is high in efficiency and compact in structure. Through changing numbers and positions of the permanent magnets and the electromagnets, the invention can realize the application occasions where the clamp fastening forces are different and has a certain locking function because of adopting the electro-permanent control method. The invention can control the rotation and the rotation speed, and can realize the braking of the rotation and the control of the rotation friction damping. Besides, the invention can also be applied in developing the elevator, the conveying belt and the development and realization of the space traffic tool.

Description

technical field [0001] The present invention relates to clamping and clamping technology, in particular, to an electromagnetic self-adaptive clamping and clamping device and a combined clamping and clamping device, especially in the technical field of electromagnetic permanent magnet direct drive and precision control of rotational and translational positions An adaptive controllable electromagnetic clamping and clamping device and a combined device thereof. Background technique [0002] The clamping and clamping device is mainly used in the self-locking of the spatial position of the mechanism and the clamping of the inchworm movement. Active control of the clamping and locking of the target object is realized by controlling the working state of the clamping and clamping device. Existing clamp locking devices are mainly mechanical locking mechanisms, which cannot be controlled independently, have low efficiency, and can only be used in specific occasions. In particular, w...
