Problems solved by technology

[0006] The driver of the present invention is designed to include two or more simple parallel-connected lead screws, matching nuts and transmission mechanisms as redundant drive input sources, and a redundant input drive mode that is uniformly output by the same moving platform, so the structure is simple and the cost is low. The advantages of low cost, reliable operation, and no risk of hydraulic oil leakage pollution are obvious, especially the designed connecting rod mechanism connecting each nut can make any nut rotate, and at the same time drive the other nuts to generate implicated rotation, forming a drive The internal force balance mechanism effectively solves the problem of unbalanced force of redundant input drive, and can complete the role of stably and evenly sharing the total drive force

Embodiment Construction

[0016] Further describe the present invention below in conjunction with embodiment and accompanying drawing thereof:

[0017] Redundant input drivers of the present invention (see figure 1 , hereinafter referred to as the driver) is characterized in that it includes a base 1, two or more than two lead screws 2 installed in parallel on the base 1, each lead screw 2 is equipped with a nut 4, each The nuts 4 are respectively connected with a moving platform 6 sleeved on all the lead screws 2 through the bearings 3 , and the nuts 4 are connected by the transmission device 5 .

[0018] The working principle of the redundant input driver of the present invention is: the screw 2 connected to the base 1 is connected to the moving platform 6 through the nut 4 and the bearing 3; the screw 2 is the input power source, and it can only Pure rotation relative to the base 1; the transmission device 5 is connected to each nut 4. When a certain nut rotates, it can drive the rest of the nuts ...

Abstract

The invention relates to a redundant input driver, which is characterized in that it comprises a base, two or more screw screws installed in parallel on the base, each screw screw is equipped with a nut, and each nut is respectively It is connected with a moving platform set on all lead screws through bearings, and the nuts are connected by a transmission device. The redundant input driver of the present invention has the advantages of simple structure, easy control, uniform input, long service life, low manufacturing cost and no pollution. One of its typical uses is to use it as a driving module alone or in parallel to connect to a simulation device of two-dimensional or more than two-dimensional motion.

Description

technical field [0001] The invention relates to the field of mechanics, in particular to a redundant input driver with simultaneous input of two or more mechanical signals and output of only one mechanical signal and its application technology. Background technique [0002] Redundant input drive technology is a drive technology in which two or more mechanical signals are input simultaneously and only one mechanical signal is output. Its main function is to use multiple driving sources to share the driving technology of a total driving force (see the literature "A Local Parallel Redundant Drive Manipulator" (T. Kokkinis, P. Millies. A parallel Robot-Arm Regional Structures with Actuator Redundancy. Mechanism and Machine Theory.1991, 26:629-64) and "Kinetostatic Performance of a Dynamically Redundant Parallel Manipulator" (T.Kokkinis, P.Millies.Kinetostatic Performance of a Dynamically Redundant Parallel Manipulator.Int.Journal of Robotics and Automation.1992 , 7:30-37)).
