Hydraulic feeding mechanical hand

Abstract

The invention discloses a hydraulic feeding mechanical hand which comprises an arm assembly (1), a rotary wrist assembly (6) and a clamping type hand assembly (7). The arm assembly and the clamping type hand assembly are connected through the rotary wrist assembly (6). The arm assembly comprises an arm lifting mechanism (2), an arm bearing and positioning mechanism (3), an arm rotating mechanism (4) and an arm telescopic mechanism (5). The arm lifting mechanism is provided with the arm bearing and positioning mechanism in a fixedly connected mode through a fastening bolt (8). The arm bearing and positioning mechanism is provided with the arm rotating mechanism in a matched mode. The arm rotating mechanism is provided with the arm telescopic mechanism in a matched mode. According to the hydraulic feeding mechanical hand, structural design is simple and reasonable, applicability is quite good, a guide sleeve can be effectively prevented from sliding and tilting in the lifting process, buffer force can be provided when an arm descends, and the stroke of all the components in the device can be effectively controlled when the components are operated.

Description

technical field [0001] The invention relates to the technical field of mechanical automation control, in particular to a hydraulic feeding manipulator. Background technique [0002] Manipulators are now mainly used in machine tools, loading and unloading, and welding. They all work according to the program. Foreign countries are developing manipulators towards intelligence. It enables it to make different command changes according to changes in the external environment. Now there are generally two trends. One is to combine the development of manipulators with intelligent robots; the other is to combine the development of manipulators with special chemical industry robots. The structure design of the existing loading manipulator is unreasonable. When the loading manipulator moves up and down again, the guide sleeve is likely to slide and tilt, posing a safety hazard. The tilt of the guide sleeve can easily cause the lifting position to be inaccurate; A downward impact fo...

Problems solved by technology

The structure design of the existing loading manipulator is unreasonable. When the loading manipulator moves up and down again, the guide sleeve is likely to slide and tilt, posing a safety hazard. The tilt of the guide sleeve can easily cause the lifting position to be inaccurate; A downward impact force will be generated during the downward movement, which will easily cause damage to the internal parts of the device for a long time, resulting in the failure of the device to operate, and the safety of the device cannot be effectively guaranteed, and the components in the device cannot be controlled by each component during operation. The stroke is effectively controlled, the loss is high, and the life is short
