Control method for normally riveted curved member

Abstract

The utility model relates to a control mode for the rivet joint quintessence piece with normal direction. A square array is arranged on the same horizontal plane which is situated just above the spare parts. The square array is composed of four measuring transducers which are arranged via the diagonal line center of the automatic riveter axle. Four servo-moving parts hang the spare parts on the three points at both sides hereof via the iron chain, so as to construct a suspended spare parts carriage. Four sensors are respectively used to control the hoisting of four moving parts. According to actual conditions, the data processing software is adopted to ascertain the sensor value at the theoretical position of the normal direction. Also, as per the error, the tolerance zone is worked out to correspond with the observed value of the sensor. The vertical adjustment shall be made for the corresponding points of the spare parts. The riveting signal shall not be sent out until the altitude difference of the four points is limited within the allowable scope. The utility model introduces the three-point suspension spare parts carriage which replaces the normal direction control via the artificial vision, so as to realize the control for the normal direction riveting of the quintessence piece which can not be solved through the four-point side-by-side mounting spare parts. Therefore, the utility model has the advantages of low cost, high efficiency and reliability.

Description
