Four-freedom heavy-load mechanical arm

Abstract

The invention discloses a four-freedom heavy-load mechanical arm. The four-freedom heavy-load mechanical arm mainly comprises a primary big arm, a secondary big arm, a forearm, a paw and a posture keeping mechanism, wherein the tail end of the primary big arm and the tail end of the auxiliary big arm are separately connected to a waist rotating mechanism through supporting shafts; the waist rotating mechanism is fixedly arranged on the base; the base is connected to the ground through a bolt; the secondary big arm is connected to the primary big arm through a secondary big arm pull rod; the forearm is mounted at the front end of the primary big arm; the paw is mounted at the front end of the forearm; and the posture keeping mechanism guarantees the tail end of the pawl to be horizontal. According to the mechanical arm disclosed by the invention, different performing mechanisms are additionally arranged at the tail end of the pawl to accomplish different work, so that the four-freedom heavy-load mechanical arm can be applied to various fields such as stacking and carrying. Load lifting ability of the mechanical arm can be 3000 kg.

Description

technical field [0001] The invention relates to a four-degree-of-freedom heavy-duty mechanical arm, which belongs to the field of robots. Background technique [0002] With the development of science and technology and the demand of market development, industrial robots have played an increasingly important role in improving production efficiency, improving economic benefits, ensuring product quality, improving working environment and optimizing industrial layout, etc., and have become the field of industrial automation. One of the indispensable tools, favored by users and quickly occupying the market. However, at present, a large part of the world's heavy-duty industrial robot market share is occupied by foreign robot companies, among which the four well-known industrial robot families account for more than half of the robot market share. Although powerful robot companies in my country have developed a variety of robots one after another, their structure is the same as tha...
