Multi-coordinate machining center combination method based on vision and movable mechanical arm

Abstract

The invention provides a multi-coordinate machining center combination method based on vision and a movable mechanical arm, and aims to overcome the large technical defect that a movable robot, a boring machine, a milling machine, a drilling machine and the like cannot be directly combined into a multi-coordinate machining center. The method comprises the steps that machining tasks and procedures are set on the movable mechanical arm, the boring machine, the milling machine and the drilling machine; a movable mechanical arm rail and clamps are arranged, a CCD and a laser ranging device or a connect camera is arranged on the movable mechanical arm, and a plurality of light mark points are arranged on the boring machine, the milling machine and the drilling machine towards the movable mechanical arm rail; then a workpiece to be machined is moved to a preset position by the movable mechanical arm through multi-joint control of the movable mechanical arm; and meanwhile, online locating monitoring and error correction are carried out in the machining process, fault alarms are given to a machining system, and multi-coordinate machining center combination is achieved. The great technical aim of directly combining the mobile robot, the boring machine, the milling machine, the drilling machine and the like into the multi-coordinate machining center is achieved.

Problems solved by technology

[0006] In order to overcome the major technical defect that the mobile robot and the boring, milling, drilling and other machine tools cannot be directly combined into a multi-coordinate machining center, this invention proposes a multi-coordinate machining center combination method based on vision and mobile manipulator. Robotic arm and boring machine, milling machine, and drilling machine set up processing tasks and procedures; set up the track and fixture of the mobile arm, and install CCD and laser distance measuring or connect cameras on the mobile arm, and face the track of the mobile arm on the boring machine, milling machine, and drilling machine Set multiple light marking points, and then the multi-joint control of the mobile robot arm will make the mobile robot arm move the workpiece to the predetermined position. At the same time, it will perform online positioning monitoring and error correction during the processing process, and give a fault alarm to the processing system. , realized the combination of multi-coordinate machining centers, and solved the major technical problem of directly combining mobile robots with boring, milling, drilling and other machine tools into multi-coordinate machining centers
