Method for repairing connecting piece

Abstract

The invention discloses a method for repairing a connecting piece. The method comprises the following steps of 1, putting a to-be-repaired bolt between limiting assemblies, so that the axis of the bolt is perpendicular to a mounting plate and the head of the bolt is in contact with the mounting plate; 2, rotating support arms in the limiting assemblies so that limiting plates can get close to eachother; 3, rotating the limiting plates so that a plate surface, far away from the corresponding support arm, of each limiting plate can be perpendicular to the upper surface of the mounting plate andbe in contact with the side wall of the bolt till the bolt is limited from moving through the limiting plates; and 4, then, cutting away a damaged thread at the tail end of the bolt through a planingand cutting tool. By means of the method, labor intensity of workers is lowered, and the situation that the bolt is taken away by the cutting force, so that bolt repairing work cannot be completed smoothly is avoided.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a method for maintaining a connecting piece. Background technique [0002] A bolt is a mechanical part, a cylindrical threaded fastener with a nut. A bolt is a type of fastener consisting of a head and a screw rod, which needs to be matched with a nut to fasten and connect two parts with through holes. This connection form is called bolt connection. Since the two parts can be separated by unscrewing the nut from the bolt, the bolt connection is a detachable connection. [0003] There are three types of bolts: A, B, and C. The first two are refined bolts, less used. Generally speaking, bolts refer to C-level ordinary bolts. In some temporary connections and connections that need to be disassembled, C-level ordinary bolts are commonly used. Common bolts commonly used in building structures are M16, M20, M24. Some rough bolts in the mechanical industry may have a relatively large diame...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a method for repairing connecting parts, which solves the problem of fixing the head of the bolt by hand when cutting off the damaged thread at the end of the bolt shank. This operation method not only increases the labor intensity of the workers, but also the bolt is easily damaged The force of the removal is taken away, so that the repair work of the bolt cannot be successfully completed
