Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problems of high cost, large weight and volume, and too much energy consumption in the existing connecting device during the connecting task, the present invention proposes an electromagnetic self-locking planar connecting device, which An electromagnetic-spring thruster with a smaller power can be used to meet the demand of bearing a large load (the load is borne by the elastic force of the spring inside the thruster, so the load size is determined by the selected spring), which can not only reduce the cost, but also effectively reduce the The volume and weight of the connection device, in addition, because the connection device in the present invention has a self-locking function, so after the connection device completes the connection task, the driver can be powered off to save energy, and there is no need to worry about the problem of disconnection after power failure

Embodiment Construction

[0015] The technical solutions of the present invention will be further described below in conjunction with specific implementation examples.

[0016] as attached Figure 1-4 As shown, the present invention includes connecting plane disc 1, catch buckle interface 2, gripper rotating fixed shaft seat 3, gripper 4, slide rail fixed base 5, slide rail 6, rack 7 that can slide on the slide rail, electromagnetic - Spring pusher 9 and push rod 8, gear 10 cooperating with the rack.

[0017] Among them, four identical buckle interfaces 2 are evenly distributed on the circumference of the connection plane disc 1, that is, the angles between adjacent buckle interfaces are all 90°. Four identical buckle interfaces 2, two of which are in opposite positions (that is, at an angle of 180° apart) are used as the buckle interfaces, and the other two interfaces are used to install the gripper 4 . The gripper 4 is fixed by the gripper rotation fixed shaft seat 3, and the gripper has only rotat...

Abstract

The invention belongs to the technical field of space modularization mechanism butt joint, and specifically relates to an electromagnetic self-locking plane connection device. According to the electromagnetic self-locking plane connection device, the mode that electromagnetic force and transmission of a gear and a rack are combined is adopted, and butt joint is achieved through the rotation of clamping jaws; due to the fact that driving of electromagnetic force is simple, complex controllers and speed reduction devices on which motor driving relies are not needed, the production cost of the connection device is reduced, and the size and weight of the connection device are effectively reduced; due to the fact that the connection device has a self-locking function, and after a connection task is completed through the connection device, an actuator can be de-energized without the worry of the problem that connection is broken after the actuator is de-energized, so that the reliability of the connection is improved.

Description

technical field [0001] The invention belongs to the technical field of space docking, and in particular relates to a planar connection device and an electromagnetic self-locking mechanism adapted to the connection of variable-configuration modules. Background technique [0002] There are generally two problems in the existing common connection devices: first, if the connection device bears a large load, it is necessary to replace a driver with a higher power, which increases the cost of the connection device on the one hand, and on the other hand, uses power Larger drives will also directly increase the volume and weight of the connection device; second, after most connection devices complete the connection task, the drive needs to be kept powered on at all times to prevent the connection from being disconnected, which consumes a lot of energy. [0003] Therefore, the existing connection device has problems such as high cost, large weight and volume, and too much energy cons...
