And drilling is used for replacing boring in the single-matched processing of the pin hole, so that the common drilling machine can replace a high-precision numerical control machine. The positioning device is economical and practical, accurate in positioning and reliable in precision, the deviation of the position degree and the aperture size of the pin hole finished by single-configuration processing is less than 0.025mm, and the requirements of design and process use are met. The time for manual adjustment, alignment and positioning can be greatly shortened by more than 85%, the whole adjustment, alignment and positioning process does not need the detection and measurement cooperation of processing equipment, the production cost is greatly reduced, and the shutdown and maintenance time of a production line of a rolling mill is shortened. When the device and the method are applied to the single-matched machining of the pin holes of the gear sleeves of the similar gear couplings, the limitation of machining equipment is avoided, a manufacturer only having common machining equipment can realize the machining and matching of the products, and the device and the method have the beneficial effects.
