X-shaped large arm for laser cutting of industrial robot

Abstract

The invention discloses an X-shaped large arm for laser cutting of an industrial robot. An integrated servo motor J2 input gear shaft, a J2RV speed reducer and a J2 bearing are installed at the two ends of a J2 casting workpiece correspondingly; outer rings of a J2 gear shaft positioning bearing and the J2 gear shaft positioning bearing position the right half side of the X-shaped large arm; outer rings of the J2 bearing and a J3 bearing position the left half side of the X-shaped large arm; an integrated servo motor J3 input gear shaft, a J3RV speed reducer and a J3 bearing are installed at the two ends of a J4 casting machining part correspondingly; a gear of the integrated servo motor J3 input gear shaft is meshed with the J3RV speed reducer to conduct speed reduction motion; and the output end of the J3RV speed reducer drives a J4 shaft, a J5 shaft and a J6 shaft to move. According to the X-shaped large arm for laser cutting of the industrial robot, the large arm offset structure of a traditional robot is improved, errors caused by bending moment and elastic deformation due to the self weight are eliminated, free rotation of the X-shaped casting large arm and stable operation of the wrist and the wrist body are guaranteed, meanwhile, bending moment and elastic deformation caused by the self weight of the robot are eliminated, and the motion precision is high.

Description

technical field [0001] The invention relates to the technical field of industrial robot processing and manufacturing, in particular to an X-shaped arm of an industrial robot used for laser cutting. Background technique [0002] An industrial robot is a multi-joint manipulator or a multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and is a machine that realizes various functions by its own power and control capabilities. Industrial robots are composed of three basic parts: main body, drive system and control system. [0003] At present, domestic and foreign industrial robots used in the market, the arm joint RV cycloid gear reducer of the robot, all adopt the way of offset installation of the arm, such as figure 1 As shown, J1 axis 1 is the joint 1 axis of the industrial robot, J2 servo motor 5 and J2RV reducer 3 are respectively installed at both ends of J2 casting workpiece 2, J2 servo motor 5 is installed with J2 input gear...
