Gravity balancing device of robot arm

Abstract

The invention discloses a gravity balancing device of a robot arm. The gravity balancing device of the robot arm comprises a frame mechanism, wherein the frame mechanism comprises a first plate, a second plate and a third plate. The first plate, the second plate and the third plate are connected through a plurality of long screws, and the long screws are inserted into the four corners of the thirdplate; a first cushion tube is arranged at the long screw located between the third plate and the second plate, a plurality of first nuts is arranged on a panel of the side, close to the first plate,of the second plate, the first nuts are connected to the long screws in a threaded manner, and an inserting groove is formed in the side face, far away from the second plate, of each first nut; a second cushion tube is inserted in each inserting groove, and each second cushion tube is inserted into the long screw located between the corresponding first nut and the first plate; and a second nut isarranged on a panel of the side, far away from the second plate, of the first plate, and each second nut is in threaded connection with the corresponding long screw. The gravity balancing device of the robot arm is novel in structure, simple in principle, convenient to use, novel and practical.

Description

technical field [0001] The invention belongs to the technical field of robotic instruments, and in particular relates to a gravity balance device for a robot arm. Background technique [0002] When the robot arm grabs or lifts some heavy objects, its gravity balance will be greatly affected. If it is not adjusted to a certain extent, the robot arm may bend or break. In the existing technology, the monitoring and control system of gravity balance is relatively complete, but the lack of the gravity balance device paired with it has many disadvantages, such as vibration during adjustment, unstable transmission mechanism, etc., and there are improvements and market vacancies. Therefore, the present invention provides a robot arm gravity balance device to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a robot arm gravity balance device in order to solve the above problems, which solves the problems in the prior ar...
