Guitar sound hole grinding machine

Abstract

The invention discloses a guitar sound hole grinding machine. The guitar sound hole grinding machine comprises a working table. A clamp device is arranged on the working table. A drilling device is arranged above the clamp device. A driving device is arranged above the drilling device. The clamp device comprises a driving motor. A rotary shaft of the driving motor is connected with a driving gear.The driving gear is engaged with a driven gear. The driven gear is connected with the center of a threaded rod. The left portion of the threaded rod is provided with a thread I, and the right portionof the threaded rod is provided with a thread II. The directions of the thread I and the thread II are opposite. The thread I is connected with a left clamp mold, and the thread II is connected witha right clamp mold. The bottom of the left clamp mold and the bottom of the right clamp mold are each connected with a sliding body. The sliding bodies are arranged in slide rails. The slide rails arearranged on the table surface of the working table. The guitar sound hole grinding machine has the advantages that the sound hole grinding effect and quality are good; the quality problems of sound hole out-of-roundness and grinding unevenness are not likely to occur; the tone quality and timbre of guitars are ensured; the grinding efficiency is high; and the guitar sound hole grinding machine issuitable for large-scale production.

Description

technical field [0001] The invention relates to the field of guitar production, in particular to a guitar sound hole grinding machine. Background technique [0002] A guitar is a plucked string instrument, usually with six strings, and shaped like a violin. At present, various industries are also continuously mechanically automated, but there are still many processing steps that are manually completed by technicians in the acoustic guitar production industry. Among them, after the assembly of the guitar speaker is completed, the panel, side panel and back panel of the speaker need to be polished and polished. When the panel is polished and polished, a very important part is to polish the sound hole. The sound hole of the guitar is not only for decoration, but also an important structure that is directly related to the pronunciation effects such as timbre and volume. Most of the sound holes of the guitar are perfectly circular and are located in the center of the left and ri...

AI Technical Summary

Problems solved by technology

The grinding of the sound hole is currently done manually, but if the manual grinding of the circular sound hole is not skilled, it will often cause quality problems such as out-of-round and uneven grinding after the sound hole is polished, and this will be serious. It affects the sound quality of the guitar, and the sound is not round; at the same time, the efficiency of artificial sound hole polishing is low, which affects the large-scale production of enterprises

[0003] To sum up: the existing technology has the disadvantages that the sound hole is not round and the grinding is uneven, which seriously affects the sound quality and timbre of the guitar, and the grinding efficiency is low, which is not suitable for large-scale production of enterprises.
