The present invention relates to the technical field of musical instrument drum polishing equipment, and discloses an automatic regulating device for drum head polishing of a musical instrument; the device includes a base; an upper end of a bracket is connected to a traveling plate, a spiral groove forms in the traveling plate, an inclination stand forms in an upper end face of the traveling plate, an inclination sliding block is connected to an upper end of the traveling plate, a right end of a lower part of a first slide bar is connected to a bracket base, a metal ball is connected to a right end of the bracket base, and a supporting rod is in sliding connected to the outer side of the first slide bar. The inclination sliding block is driven to slide on the traveling plate through the first slide bar, the inclination sliding block moves upwards with respect to a support rod, the metal ball slides on a variable resistor, the horizontal displacement of the inclination sliding block isreversely concluded through the inclination of the inclination stand to determine the position of a grinding device, and the length of a telescopic rod is controlled through current change between themetal ball and the variable resistor; therefore, this structure solves the problem that the existing drum head polishing device unevenly grinds the drum head due to constant pressure.
Description
technical field [0001] The invention relates to the technical field of musical instrument drum polishing equipment, in particular to an automatic adjustment device for drum surface polishing of musical instruments. Background technique [0002] Musical instruments generally refer to tools that can be used to play a certain tone or rhythm in various ways. In China, they are generally divided into national musical instruments and Western musical instruments. The production of musical instruments is different from the production of general industrial products. It not only requires the product to have a reasonable and exquisite appearance, but also must have good acoustic quality, including timbre, music and specified pitch height. Therefore, the selection of materials is very strict. Musical instruments are instruments that can not only produce musical sounds, but also recreate musical art. Human beings can express and exchange thoughts and feelings by playing musical instrumen...
