Abstract
The invention relates to a method for manufacturing a both-end automatic centering clamping mechanism. The hardening and tempering hardness of a mandrel and a rotating shaft is 28-32HRC, and both ends of the mandrel and the rotating shaft are processed into centre holes with protecting chamfers. The assorted shaft shoulders and end surfaces of the mandrel and the rotating shaft are ground out with the end surface of a grinder grinding wheel when an excircle is accurately ground. The grinding wheel is utilized to cut out a chuck jaw step; a chuck body is arranged on a lathe main shaft to support the crown face and the end surface of the small circular ring fine turning chuck jaw step to finely turn the mesopore of the chuck body. Two groups of chuck jaws are arranged in the corresponding chunk body to respectively brace big circular rings arranged on both ends of the mandrel near the chunk wire edge chuck jaw step. The assembled both-end automatic centering clamping mechanism is arranged on a flange plate of a dividing head by the large bore of the chunk body and the end surface of the left end chunk; the tip of the dividing head supports against the centre hole of the rotating shaft; the outer planes of the chunk jaws of both ends of the clamping mechanism are processed at the same time; and all chunk jaws are processed through scale division. Therefore, the positioning precision of the clamping mechanism is high.
