AI Technical Summary

Technical Problem

The tapping and chamfering of nuclear power plant nuts cannot be performed quickly in multiple stations on a single machine, resulting in extended processing cycles, low production efficiency, and reduced yield.

Method used

Design a multi-station device that includes a tapping assembly, a chamfering assembly, and a reversing assembly. The device clamps and flips the nut using a clamping component, and inspects the thread using a detection assembly, thus achieving integrated tapping and chamfering processing. Processing is stopped promptly if the thread fails to meet the requirements.

Benefits of technology

This significantly shortened the single-piece processing cycle of nuclear power plant nuts, improved production efficiency, and ensured processing quality through inspection components, preventing the generation of defective products and increasing the yield rate.

Abstract

The invention discloses a multi-station device for nuclear power nut thread machining and a machining method of the multi-station device, and particularly relates to the technical field of nuclear power nut machining, the multi-station device comprises a clamping piece and a fixing piece which are arranged in an equipment body, the clamping piece can clamp a nut by moving, and the fixing piece can drive the clamping piece to turn over by rotating; the detection assembly comprises a first installation part and a second installation part which are arranged on the equipment body, a detection part is arranged in the first installation part, and when chamfering machining is conducted on the nut, the detection part can detect threads of the nut and conduct positioning and supporting on the axis of the nut; the nut is clamped and positioned through the clamping piece during tapping, after thread machining is completed, the machining direction of the nut is changed through the reversing assembly, and therefore integrated machining of tapping and chamfering is achieved, the machining quality of the last procedure is inspected through the detection piece, and the machining efficiency is improved. And continuous labor hour investment on unqualified products and generation of more defective products are prevented.
