Embodiment Construction

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention provides a finger steering engine and a robot hand. The finger steering engine comprises a driver, a changeover mechanism, a lead screw and a nut. The driver is used for providing a power source, the changeover mechanism is connected with an output shaft of the changeover mechanism, and an output shaft of the changeover mechanism is parallel to the output shaft of the driver. The lead screw is fixedly connected with the output shaft of the changeover mechanism, and the nut is in threaded connection with the lead screw. According to the finger steering engine and the robot hand, the finger steering engine outputs a single freedom degree and is used for controlling one or two fingers to be bent, power distribution is not needed, and the structure of the finger steering engine is simplified. By arranging the changeover mechanism, the relative positions of the driver and the lead screw can be adjusted, the space of a single finger steering engine is reduced, and the mountingneeds of multiple finger steering engines are met; and in addition, the lead screw has a self-locking function, and therefore the finger steering engine can be prevented from being pushed from the finger ends, and the internal structure of the steering engine is protected.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to a finger steering gear and a dexterous hand. Background technique [0002] At present, scientific research institutions and enterprises are doing more and more research on robots, and the requirements for the precision of robot hand movements are getting higher and higher. In order to meet the precision requirements of hand movements, human-like dexterous hands have gradually become a development trend. [0003] The movements that can be achieved by dexterous hands are relatively complex. Correspondingly, the structure of the steering gear of the hand is also relatively complicated. Transmission mechanisms such as bevel gears, worm gears, worms, and connecting rods are required to realize power distribution and transmission control of each finger. Contents of the invention [0004] The purpose of the present invention is to provide a finger steering gear to solve...
