Double-input synchronous drive interface module

Abstract

The invention provides a double-input synchronous drive interface module, which is characterized in that the module comprises an output rod, a regulation bar, a base and two chains, wherein the two chains are connected between the regulation bar and the base and have the same structure; one end of the output rod and the base form a shifting pair, and the other end of the output rod is connected with the middle part of the regulation bar through a third rotation pair; the two ends of the regulation bar are respectively connected with the base through a branched chain; and each branched chain comprises a connection rod, guide rails and sliding blocks, wherein one end of the connection rod is connected with the regulation bar through a second rotation pair, and the other end of the connection rod is connected with the sliding blocks through the rotation pair, the sliding blocks and the guide rails fixed on the base form the shifting pairs, and the rotation axes of the first, second and third rotation pairs are mutually parallel and vertical to the motion tracks of the sliding blocks. In the invention, the two sliding blocks on the guide rails are driven so as to obtain straight displacement output on the output rod and allow the two sliding blocks to have different input speeds, thereby solving the synchronous drive problem between two input devices.

Description

technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to a dual-input synchronous drive interface module. Background technique [0002] Redundant drive technology can realize simultaneous action of multiple mechanical input signals, while maintaining only one mechanical signal output drive technology. Since multiple mechanical signals are input at the same time, it can effectively reduce the power of a single driving source, improve the stress of the entire system, and realize heavy-duty driving at the output end. At present, most lead screw drive systems are driven by a single lead screw. If two lead screws are directly connected in the saddle, since the rotation of the drive motor must be kept synchronous, the design of the control system requires extremely high precision, and the reliability is still not guaranteed. . The same problem also exists in other similar mechanical transmission systems. In order to solv...
