Problems solved by technology

When processing with a plane, an ax and other tools, the cover plate to be processed may shake back and forth during processing, which brings difficulties to the workers during processing, which makes the worker have to process the cover plate against a certain place. During processing, due to the force, it may lead to change and deformation, and the processed piano cover does not meet the requirements for use.

Abstract

The invention discloses a clamping device for a piano cover plate. The clamping device comprises a baseplate and two clamps; the clamps are mounted at the two ends of the baseplate respectively; each clamp comprises a base, a handle, a rotator and a clamping body; the bases are mounted on the baseplate; the rotators are mounted on the bases; the handles are hinged onto the bases, and push the rotators to rotate; the clamping bodies are mounted on the rotators, and rotate along with the rotation of the rotators. The clamping device conducts spacing on the piano cover plate; during processing, the piano cover plate is prevented from moving back and forth, so that a worker can machine the piano cover plate conveniently.

Description

technical field [0001] The invention relates to equipment used in piano processing, in particular to a clamping device used in processing piano cover plates. Background technique [0002] The piano (Italian: pianoforte) is a keyboard instrument derived from Western classical music, consisting of 88 keys (composed of 52 white keys and 36 black keys) and a metal string soundboard. The sound range is wide, from A2 (27.5Hz) to C5 (4186Hz), almost including all the tones in the tone system. It is widely used in performances such as solo, ensemble, and accompaniment. It is very convenient for composing and rehearsing music. [0003] The player presses the keys on the keyboard, moves the small mallet covered with felt inside the piano, and then strikes the steel strings to produce sound. The piano is known as the king of musical instruments because of its wide range and beautiful timbre. [0004] The main structure of a piano includes pedals, tuning pegs, hammers, dampers, actio...
