Problems solved by technology
The existing calibration methods mostly use manual calibration to determine the mold coordinate system. During the calibration process, the contact side head installed on the main body of the machine tool is manually controlled to touch the target ball on the mold. The precision of the mold coordinate system thus calibrated is relatively low. Poor, and the calibration accuracy is closely related to the proficiency of workers

A contact-type automatic calibration device and method for composite material laying equipment, including three parts: a calibration probe, a ball and a control system; wherein the calibration probe and the ball are respectively installed on the machine tool body and the mold; the calibration probe There is a contact switch inside the head and it is connected to the control system. When the calibration probe touches the ball, the control system automatically records the current position information of the machine tool; through the control program, the calibration probe touches the ball according to the set movement track, And record the position information of all contact points; the control system calculates the coordinates of the center of the ball in the machine tool coordinate system according to the measured coordinate points, and completes the mold calibration. The automatic calibration process and efficient fitting algorithm of the present invention can greatly improve the calibration accuracy and calibration efficiency during equipment calibration, and reduce the influence of human factors on the quality of final parts.
Description
technical field [0001] The invention relates to the technical field of fiber laying, in particular to a contact-type automatic calibration device and method for composite material laying equipment.
