Abstract
The invention relates to a method enabling a gun clamper to stop on the middle position of an oscillating range and an oscillator of a welding gun clamper using the method. The oscillator of the welding gun clamper comprises an electric motor, a transmission assembly, a driving oscillating rod, a driven oscillating rod and a gun clamper for clamping a welding gun. The oscillator is provided with a sensor used for detecting the oscillating position of the driven oscillating rod and a control circuit for feeding back the position of the driven oscillating rod, wherein the control circuit comprises the sensor, a relay and the electric motor. When a control switch of the oscillator of the welding gun clamper is pulled to the oscillating-stop position, the sensor is electrified to enable the sensor to generate an effective-control signal to the relay when the driven oscillating rod is oscillated to the middle position of the oscillating range; the relay cuts off the power supply of the electric motor to stop the oscillation of the gun clamper, and the gun clamper stops on the middle position of the oscillating range. The method enabling a gun clamper to stop on the middle position of an oscillating range precisely positions the gun clamper in the oscillating range by means of mechanical tracking and circuit feedback, simplifies the operation steps of the operating staff and guarantees the precision and the welding quality of the oscillating welding.
