Description

Piano pedal vibration machine

Technical Field

The invention relates to the technical field of piano processing and manufacturing, in particular to a pedal rhythm machine for a piano.

Background

The piano is a keyboard instrument in Western classical music and is known as the king of the instrument. It is composed of 88 keys and a metal string soundboard. The range of the piano pitch range covers almost all tones in the tone system, and is the instrument with the widest pitch range except for the pipe organ. The piano is commonly used for solo, repetition, accompaniment and other performances, and is very convenient for composing music and rehearsing music.

The damper pedal of the piano needs to be continuously stepped in the manufacturing process of the piano so as to adjust the damper of the piano to be synchronously opened. In the traditional production process, a worker is required to continuously tread the damper pedal for tens of minutes by feet. The production process has the advantages of high labor intensity, high requirement on labor skills, low automation degree and influence on production efficiency.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1, in an embodiment of the present invention, a piano pedal rhythm machine includes a metal frame 2, a rectangular frame slider 4 and a pedal linkage block 9, wherein a motor 1 is mounted on the metal frame 2, an eccentric wheel 3 is mounted on an output end of the motor 1, the rectangular frame slider 4 is mounted on the metal frame 2 and is in sliding fit with the metal frame 2, specifically, a guide rail is disposed on the metal frame 2, the rectangular frame slider 4 is mounted on the guide rail and is used for guiding the movement of the rectangular frame slider 4, the sliding fit modes are many, and no specific limitation is performed here, the rectangular frame slider 4 is sleeved outside the eccentric wheel 3 and can convert the rotation of the eccentric wheel 3 into the lifting movement of the rectangular frame slider 4, the bottom of the rectangular frame slider 4 is connected with the pedal linkage block 9 through a polished rod 5, and the motor 1 is electrically connected with a power supply and a switch.

Quick clamp 7 is installed to metal crate 2's bottom, and can know from the attached drawing, and the handle portion of quick clamp 7 is articulated with metal crate 2, and when the handle portion rotated, the chuck part of quick clamp 7 can stretch out or retract, and one side position of metal crate 2 is fixed with the metal extension board 8 relative with the chuck part of quick clamp 7, and quick clamp 7 mainly used realizes the quick fixed between this device and the piano, and the fixed process is as follows: the metal frame 2 is close to the right side of the damper pedal of the piano, the metal support plate 8 is close to the inner side of the pedal rail of the piano, the handle part of the quick clamp 7 is rotated, the chuck part of the quick clamp 7 is close to the metal support plate 8, and the pedal rail of the piano is clamped between the quick clamp 7 and the metal support plate 8.

The working principle of the embodiment is as follows: firstly, the device is fixed at a piano pedal position according to the method, meanwhile, the pedal linkage block 9 is close to a piano damper pedal, the driving motor 1 and the eccentric wheel 3 rotate synchronously, the rotation of the eccentric wheel 3 is converted into the lifting motion of the rectangular frame sliding block 4, the pedal linkage block 9 moves synchronously to drive the piano damper pedal to move up and down continuously, the function of continuously and automatically stepping on the piano pedal is realized, after the piano damper is adjusted, the power supply of the motor 1 is turned off, the quick clamp 7 is opened, and the device is taken down.
