Fingerboard grinding device for wooden guitar production

Abstract

The invention discloses a fingerboard grinding device for wooden guitar production, and relates to the technical field of guitar production. The fingerboard grinding device for wooden guitar production comprises a box. The lower portion of the left side of an inner cavity of the box is rotationally connected with a threaded rod, and the right end of the threaded rod penetrates the right side wallof the box and extends to the right side of the box. The left side and the right side of the surface of the threaded rod are in threaded cup joint with a first thread block and a second thread block correspondingly. The top of the first thread block and the top of the second thread block are rotationally connected with rotation rods. The two sides of the inner cavity of the box are in sliding connection with first lifting plates, and the ends, away from the first thread block and the second thread block, of the two rotation rods are rotationally connected with the bottoms of the correspondingfirst lifting plates. According to the fingerboard grinding device for wooden guitar production, the first thread block and the second thread block are driven to move through rotation of the threadedrod, accordingly a second lifting plate is driven to ascend and descend, thus, the amplitude of compression springs is changed, and accordingly the problem of unbalanced stress of the upper face and the lower face due to the gravity influence is solved.

Description

technical field [0001] The invention relates to the technical field of guitar production, in particular to a fretboard grinding device for acoustic guitar production. Background technique [0002] The guitar, its panel and back are flat, the waist of the piano generally has no angle and is concave inward, the classical guitar generally has no depression, the neck is very wide and long, the fingerboard has string nuts and many narrow and slightly upward convex The horizontal grid made of metal is called "fret". It divides the strings into many semitones. A stringed instrument played by plucking the strings with one hand while resting the fingers of the other hand on the fretboard, the small metal strip that covers the neck. [0003] Existing guitar production fretboard grinding devices are often used for single-sided grinding intelligently, which reduces the efficiency of grinding and is not conducive to improving the efficiency of processing. Some grinding devices can also ...
