Four degrees of freedom loading and unloading manipulator

Abstract

The invention discloses a four-degree-of-freedom loading and unloading mechanical arm. The mechanical arm comprises a base and a mechanical arm, the base comprises a pedestal, a supporting column anda rotary cylinder which is arranged in a manner of rotating around the supporting column under hydraulic driving, the mechanical arm comprises an arm body and a tail end effector which is arranged ina manner that the arm body can swing left and right in the transverse plane in a reciprocating mode, and the arm body is hinged to the upper portion of the rotary cylinder body in a manner that pitching swing movement can be carried out in the vertical plane; the tail end effector comprises a first rotating shaft which can rotate around the axis of the first rotary shaft under hydraulic driving, afixed cylinder which is fixedly connected with the outer side of the first rotary shaft in the vertical direction, and a second rotary shaft which is arranged in the fixed cylinder and can rotate around the axis of the second rotary shaft under hydraulic driving; and thus the movement adjustment of four degrees of freedom can be achieved, positioning accuracy when used is greatly improved, and multi-space and multi-scenario usage can be met. The movement of each degree of freedom is adjusted through hydraulic driving, so that the whole mechanical arm has a high heavy-load bearing capacity andcan be applied to various workpieces.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, in particular to a multi-degree-of-freedom loading and unloading manipulator. Background technique [0002] The loading and unloading manipulator has been widely studied as the main key equipment in the important pillar equipment. It is mainly used in industries such as automobiles, ships, ships, aircraft, satellites, rockets, spacecraft, large machine tools, large production lines and equipment groups, and iron and steel metallurgy. The use of loading and unloading manipulators mainly has the following outstanding advantages: First, it can save human resources; some materials, especially those in comparison, often require several workers to complete. This is the use of machine tool loading and unloading devices. It can easily solve the problem; second, it can realize programmed operation, and the loading and unloading device of the machine tool can be programmed and controlled. As ...

Problems solved by technology

In order to solve this problem, a variety of mechanical structures of manipulators have appeared in the prior art, which cooperate with the hydraulic way by means of electric or pneumatic, and set the manipulator with multiple degrees of freedom to meet the requirements of heavy load and positioning accuracy. Balanced, but the multi-structure is relatively complicated, the overall space is large, and a large range of activity space is required, the use occasions are limited, and it cannot be widely used
