Description

Tool assembly for post-processing of silver plating of internal thread of nut

Technical Field

The utility model belongs to the technical field of the processing clamping device, a frock subassembly that is used for nut internal thread silvering aftertreatment particularly.

Background

In the field of aeroengines, the nut fastener usually needs to adopt an anti-bonding silver plating process due to use requirements. Because the requirement of the complete aircraft engine on residues of a silver plating process is strict, the nut fastener product mostly adopts a partial silver plating mode to reduce the risk caused by the residues. The conventional method for the local silver plating process of the internal thread of the nut mainly comprises a pre-plating insulation method, a tool shielding method and a post-plating treatment method, and the prior art mainly has the following problems in the post-plating treatment process: firstly, a post-plating treatment method is generally only suitable for nuts of one specification and has poor universality; secondly, the effective silver layer is easy to damage, and the effect is not good; thirdly, the production efficiency is low, fourthly, the tool structure is complex, and the operation is inconvenient. The clamping of the post-silver plating treatment of the internal thread of the nut is seriously influenced by the problems.

Disclosure of Invention

The utility model aims to overcome above-mentioned shortcoming and provide a simple structure, the commonality is strong, high-efficient reliable, the simple operation be used for nut internal thread silvering aftertreatment's frock subassembly.

The utility model discloses the purpose and solve its main technical problem and adopt following technical scheme to realize:

the utility model discloses a frock subassembly for nut internal thread silvering aftertreatment, including fastening nut, retaining ring, core bar, wherein: the core rod is provided with a plurality of slidable check rings, two ends of the core rod are connected with fastening nuts, the check rings are arranged between the fastening nuts, and the outer parts of the check rings are conical and are uniformly distributed on the core rod in the direction of the conical surface.

Above-mentioned a frock subassembly that is used for silver-plated aftertreatment of nut internal thread, wherein: the two ends of the core rod are provided with threads, and the core rod is connected with the fastening nut through the threads.

Above-mentioned a frock subassembly that is used for silver-plated aftertreatment of nut internal thread, wherein: the core rod is made of metal material.

Above-mentioned a frock subassembly that is used for silver-plated aftertreatment of nut internal thread, wherein: the retainer ring is sleeved on the core rod through an installation hole arranged inside.

Above-mentioned a frock subassembly that is used for silver-plated aftertreatment of nut internal thread, wherein: the retainer ring is made of plastic.

Compared with the prior art, the utility model obvious advantage and beneficial effect have. According to the technical scheme, in the tool assembly for post-processing of the silver plating of the internal thread of the nut, the core rod is provided with the plurality of slidable check rings, so that the position between the check rings can be adjusted according to the height of a nut product; the two ends of the core bar are connected with fastening nuts, threads are arranged at the two ends of the core bar, and the core bar is connected with the fastening nuts through the threads, so that the retaining rings at the two ends are fixed; the outer part of the retainer ring is in a conical surface shape, the conical surface is uniformly distributed on the core rod in the direction, and the conical surface is tightly attached to the conical surface of the nut product, so that the protection of the effective silver-plated position in the sand blowing process after silver plating is avoided, and the sand blowing quality after the silver plating is ensured; the retainer ring is made of plastic, so that the damage to the effective silver layer is avoided. In a word, the utility model discloses simple structure, commonality are strong, high-efficient reliable, the simple operation, are fit for using widely of nut internal thread silvering aftertreatment clamping.
