Abstract

The invention discloses a gravity compensating device and a robot. The robot is provided with the gravity compensating device. The gravity compensating device comprises a first executing end, a secondexecuting end and a swinging arm; the first executing end is provided with a driving shaft and a driving motor which is in transmission connection with the driving shaft; one end of the swinging armis fixed to the driving shaft, and the other end of the swinging arm is provided with a linkage shaft parallel to the driving shaft; and the second executing end is fixedly installed on the linkage shaft, a first belt wheel is fixedly installed on the driving shaft, a second belt wheel is fixedly installed on the linkage shaft, and the first belt wheel and the second belt wheel are sleeved with abelt. Compared with a traditional structure, the gravity compensating device has the advantages that gravity compensating is conducted in a mechanical mode, and the production cost can be reduced; andalgorithm compensating does not need to be conducted on the robot, the running load of a robot system is reduced, the control process of the driving motor is simplified, the stability of the robot inthe running process is improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a gravity compensation device and a robot using the device. Background technique [0002] With the maturity of automation technology, the degree of automation in the industrial production process is also getting higher and higher. Automation in industrial production processes is mostly realized by robots (also known as manipulators). During the movement of the mechanical arm of the robot, the gravity will affect it, causing the actual movement amount to deviate from the theoretical value. Therefore, the robots on the market generally perform gravity compensation through related algorithms to eliminate the deviation. This method uses software to run algorithms and feed back to relevant motors to achieve gravity compensation, which increases the structural composition and increases the cost. Contents of the invention [0003] In order to solve the above problems, the...
