Tuning peg planting equipment of piano sound source

Abstract

The invention relates to the technical field of piano manufacturing, discloses tuning peg planting equipment of a piano sound source, and solves the problems that the axial direction of a tuning peg cannot be easily aligned with the axial direction of a tuning peg hole, the tuning peg hole can be prone to being damaged when the tuning peg is pressed into the tuning peg hole, and the stability of the tuning peg is reduced. According to the technical scheme, the tuning peg planting equipment of the piano sound source is characterized by comprising a conveying roller belt and a tuning peg planting device, wherein the tuning peg planting device comprises a pressure bearing table, a loading table, an ascending and descending driving mechanism and a tuning peg planting machine; the pressure bearing table is positioned at one side of the conveying roller belt; the loading table is positioned above the pressure bearing table; the ascending and descending driving mechanism is used for ascendingand descending the loading table; the tuning peg planting machine is fixed under the loading table; the upper surface of the pressure bearing table is a pressure bearing surface; the pressure bearingsurface is inclined and downward in a direction towards the conveying roller belt; the height of the side edge, in a direction near the conveying roller belt, of the pressure bearing surface is equalto the height of the highest point of the upper surface of the conveying roller belt; a vertical tuning peg pressing rod is arranged at the lower end of the tuning peg planting machine; the tuning peg planting machine synchronously ascends and descends along with the loading table; the improvement of the stability of the tuning peg is realized; and the sound quality of the piano sound source is guaranteed.

Description

technical field [0001] The invention relates to the technical field of piano manufacturing, in particular to a peg insertion device for a piano sound source. Background technique [0002] A piano is a keyboard musical instrument consisting of strings, cast iron frame, soundboard, action system, case and other accessories. Strings are the primary component of sound production, and the main material is steel wire, which is a special steel wire specially produced for pianos and other stringed instruments. [0003] The cast iron skeleton is also called the iron row, and its production is the most important and critical. The cast iron skeleton is the carrier of the tension of the strings. The distribution of the tension of the strings should be paid attention to in the design. It mainly supports the tension of the strings up to 18-20 tons. [0004] The soundboard is composed of a soundboard, a support wood, a soundboard frame and a string code. There are also peg boards, code ...

AI Technical Summary

Problems solved by technology

[0007] Its disadvantage is that the peg hole is axially inclined, and it is not easy to align the peg axis with the peg hole axis. When the peg is pressed into the peg hole, the lower end of the peg is easy to crush the inside of the peg hole, resulting in a fixed peg Easy to loosen, reduce the stability of the peg, affect the sound quality of the piano sound source, and require frequent tuning
