Automatic correction joint of robot and control system

Abstract

The invention discloses an automatic correction joint of a robot and a control system. The automatic correction joint comprises an upper guide and correction piece and a lower guide and correction piece which are in parallel. The upper guide and correction piece and the lower guide and correction piece are connected through a pull rod. The upper guide and correction piece is fixedly connected withan upper limb of a mechanical arm through an upper pull rod cap, and the lower guide and correction piece is fixedly connected with a lower limb of the mechanical arm through a lower pull rod cap. Top balls are arranged on the upper surface of the lower guide and correction piece. The upper surfaces of the top balls are in contact with pressure sensors arranged on the lower surface of the upper guide and correction piece, and the lower ends of the top balls are connected with a hydraulic system. According to the automatic correction joint, automation of a mechanical hand correction system isachieved, precision during correction is greatly improved, the overall work efficiency of equipment is improved, and the defects that during traditional mechanical arm correction, demounting is needed, efficiency of manual correction or correction achieved by means of a correction platform is low, and the error precision is low are avoided.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to a robotic arm automatic correction joint and a control system. Background technique [0002] With the continuous development of human science and technology, the space for robot applications has become more extensive. The unknown and uncertain environment has put forward higher requirements for the functions of robot products, which has promoted the continuous improvement of robot technology. And application methods also put forward higher requirements. At present, the existing manipulator calibration generally adopts a fixed number of actions to correct, or uses a visual monitoring system for error monitoring and calibration reminders. Using actions to a fixed number of times is blind and reduces the use efficiency of the manipulator. The visual monitoring system is used. Software costs are high. Although the current manipulator has its own auxiliary origin calibration soft...
