Musical instrument key column fixing structure and method

Abstract

The invention provides a musical instrument key column fixing structure and a musical instrument key column fixing method. For the musical instrument key column fixing structure, a key column substrate is additionally arranged between a copper musical instrument tube and key columns, the key columns are fixed to the key column substrate through screws, the plurality of key columns are mounted on one key column substrate, the fixing for the plurality of key columns can be completed through once of mounting, therefore, the work amount needed by manual welding is reduced, and the automatic mechanized production is realized. The musical instrument key column fixing method provided by the invention has the advantages that the welding work amount is small, the operation is safe and environmentally, the processing technology is simple, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of musical instrument production, in particular to a musical instrument keypost fixing structure and fixing method. Background technique [0002] Many copper musical instruments need to use key columns to fix the key rods and keys, such as: saxophone, clarinet and other instruments. The key column is fixedly installed on the outside of the musical instrument's copper material pipe body or body cavity, and the top of the key column is provided with a through hole, and the key rod of the key is inserted into the through hole to realize the positioning and installation of the key. The positioning accuracy and installation firmness of the key columns directly affect the operational flexibility of the keys. The key columns in the prior art are all fixed by soldering, such as figure 1 As shown, after the instrument copper tube or cavity is processed and formed, the key columns are welded one by one. There are ma...

AI Technical Summary

Problems solved by technology

The key columns in the prior art are all fixed by soldering, such as figure 1 As shown, after the instrument copper tube or cavity is processed and formed, the key columns are welded one by one. There are many solder joints. The process of positioning and welding each key column is time-consuming and laborious. The operation is difficult for workers and the welding quality is unstable. After playing for a long time, the key columns are easy to loosen and desolder, which will affect the use of the keys

In addition, the copper pipe or cavity of the musical instrument after soldering the key posts still needs to be cleaned, polished, polished and other processing procedures, which will cause great pollution to the environment, low production efficiency, and increase the production cost of the musical instrument.
