Abstract

The invention discloses a parallelly-driven heavy-load robot. The robot comprises a fixed base, a transmission swing arm mechanism, a tail end execution assembly, a rotary driving assembly, a first swing driving assembly and a second swing driving assembly; the transmission swing arm mechanism comprises a first transmission arm assembly and a second transmission arm assembly; the first transmission arm assembly comprises a first arm body, a first connecting rod, a first connecting block and a rotating seat; the second transmission arm assembly comprises a second arm body, a second connecting rod and a second connecting block; the tail end execution assembly is installed on the second connecting block; the first arm body, the first connecting rod, the first connecting block and the rotating seat on the first transmission arm assembly form a parallelogram structure; and the second arm body, the second connecting rod, the second connecting block and the first connecting block on the second transmission arm assembly also form a parallelogram structure. The rigidity and the load capacity of the robot are ensured, the tail end execution assembly on the second connecting block is always kept in translational motion, and the adverse effect caused by an eccentric gravity moment due to the dead weight of a driving assembly is effectively reduced.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a parallel-driven heavy-duty robot. Background technique [0002] As a high-end automation equipment, heavy-duty robots are widely used in welding, handling, palletizing, spraying and other fields. With the continuous upgrading of the automation industry, the application requirements for heavy-duty robots are also increasing, especially for large-span and large-load Operation. Traditional castings are gradually exposing its limitations. The non-reconfigurable characteristics restrict the working range of the robot, making it impossible to perform large-span operations. The traditional drive motor layout makes the robot vulnerable to the gravity torque caused by the motor's own weight during the movement process. At the same time, the weight of the castings makes it difficult to further improve the load-to-weight ratio of the robot. Therefore, in order to realize the lightwe...
