The invention belongs to the technical field of threaded sleeve assembling, and relates to a controlling method of an automatic threaded sleeve assembling mechanism. The controlling method comprises the following steps that 1, a workpiece to be assembled with a threaded sleeve is installed on a workpiece positioning clamp; 2, the threaded sleeve is automatically arranged and fed, and a two-dimensional code of the workpiece is read by an operator holding a code scanning gun; 3, a workpiece positioning clamp is automatically positioned and clamped and positioning detection is carried out, 4, a transfer in-place
signal is fed back to a controlling
system by a
position sensor, and the condition that a current tightening mechanism is calibrated effectively is confirmed by the controlling
system; 5, automatic threaded sleeve screwing is carried out, and a threaded sleeve screwing mechanism outputs current hole
assembly torque data to the controlling
system; 6, a
contact type distance sensoris driven to conduct threaded sleeve depth measurement; 7, a
tail handle of the threaded sleeve is removed; and 8, a
laser sensor is driven to perform
tail handle removing confirmation detection. According to the controlling method, high-positioning and repeated-positioning precision including space angles can be achieved, damage to the threaded sleeve and a workpiece
assembly bottom hole is avoided, and automatic
assembly reduces labor intensity and greatly improves production efficiency.
