Full-automatic bolt and nut cleaning machine

Abstract

The invention discloses a full-automatic bolt and nut cleaning machine. The full-automatic bolt and nut cleaning machine comprises a supporting seat, a liquid storage box body and a sealed box body with a transparent window. A bolt locking and overturn mechanism and a bolt rotary supporting mechanism are arranged on the right side of a cleaning machine main body, the bolt locking and overturn mechanism is used for hydraulically driving a bolt to topple and overturn, the middle is locked by using a locking ring, the bolt rotary supporting mechanism adopts a V-shaped structure composed of a pair of rubber rollers and two pairs of nylon rollers, and the rubber rollers drive the bolt to rotate through driving of a motor; a nut dismounting and mounting mechanism and a nut cleaning and air drying mechanism are arranged at the left end of the cleaning machine main body, the nut dismounting and mounting mechanism is installed on a lead screw, and the nut cleaning and air drying mechanism is fixed to a cylindrical gear, matched with a linear gear, at the right end of the cleaning machine; and an oiling mechanism is located on the upper portion of a thread cleaning rolling brush, and cameras are arranged above threads at the two ends of the bolt correspondingly to monitor the cleaning state in real time. According to the full-automatic bolt and nut cleaning machine, full-automatic bolt and nut synchronous cleaning, air drying and oiling operation can be achieved, real-time monitoring can be achieved, operation is convenient, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of cleaning equipment for bolts and nuts in nuclear power reactor pressure vessels, in particular to a fully automatic bolt and nut cleaning machine. Background technique [0002] The reactor pressure vessel bolt and nut cleaning machine is suitable for cleaning and descaling the three-stage threaded part, center hole, nut and its thread of 56 M155×4 main bolts with a length of 1675mm in the reactor pressure vessel of a 650MW pressurized water reactor unit, and air-dried And oiling work, the threads must not be damaged at all during maintenance and cleaning, and at the same time, the subsequent eddy current flaw detection and inspection related maintenance activities can be carried out through automatic cleaning of the main bolts, so as to ensure that the main bolts of the reactor pressure vessel are in a long-term safe and reliable state. [0003] At present, most of the foreign bolt and nut cleaning machines are ver...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the foreign bolt and nut cleaning machines are vertical, and there are problems of inconvenient operation and observation in the operation engineering, and the cleaning of the bolt center hole is difficult. The domestic horizontal cleaning machines have the problem of difficult clamping of bolts and nuts, and the degree of automation is not enough. High, and cannot monitor the cleaning status in real time
