A parallel manipulator repetitive positioning accuracy reliability test device and method. The device includes a parallel manipulator mounting frame, a two-way material transmission simulation mechanism, an X-direction vibration simulation table and a Y-direction vibration simulation table; the X-direction vibration simulation table is located in the Y-direction vibration simulation On the platform, the two-way material transmission simulation mechanism is located on the X-axis vibration simulation table, and the parallel manipulator is installed on the two-way material transmission simulation mechanism. The method is as follows: install the parallel manipulator in place; use a two-way material transfer simulation mechanism to simulate material transfer conditions, and set a calibration position on the material conveyor belt; control the movement of the parallel manipulator through programming, and use the end of the parallel manipulator to carry out inspection on the material at the calibrated position. Picking and sorting; simulate vibration conditions through the X / Y vibration simulation platform; control the parallel manipulator to pick up and sort materials back and forth, measure the deviation between the actual movement position of the parallel manipulator end and the calibrated position on the material conveyor belt, and obtain the repeatability of the parallel manipulator Positioning accuracy data.
Description
technical field [0001] The invention belongs to the technical field of repeated positioning accuracy testing of parallel manipulators, and in particular relates to a reliability test device and method for repeated positioning accuracy of parallel manipulators. Background technique [0002] At present, modern industry is gradually developing in the direction of high speed, high quality and high intelligence. The traditional labor-intensive production process has been difficult to meet the needs of modern industrial production. More and more automated industrial robots have appeared on the production line, which has been able to It completely replaces traditional manual labor and has gradually become the main equipment of modern industrial production process. [0003] Taking the intelligent parallel manipulator as an example, it can not only replace human beings to realize fast and precise processing of complex products on a micro scale, but also can operate in harsh working c...
