Embodiment 1

[0016] see figure 1 , in an embodiment of the present invention, a piano pedal vibration machine includes a metal frame 2, a rectangular frame slider 4 and a pedal linkage block 9, a motor 1 is installed on the metal frame 2, and a motor 1 is mounted on the output end of the motor 1 The eccentric wheel 3 is installed, and the rectangular frame slider 4 is installed on the metal frame 2 and is slidably matched with the metal frame 2. Specifically, the metal frame 2 is provided with a guide rail, and the rectangular frame slider 4 is installed on the guide rail for The movement of the rectangular frame slider 4 is guided, and there are many ways of sliding fit, which are not specifically limited here. The rectangular frame slider 4 is set outside the eccentric wheel 3, which can convert the rotation of the eccentric wheel 3 into a rectangular frame During the lifting movement of the slider 4, the bottom of the rectangular frame slider 4 is connected with the pedal linkage block ...

Embodiment 2

[0020] see figure 1 , on the basis of Embodiment 1, this embodiment makes the following improvements to the pedal linkage block 9, the polished rod 5 and the quick clip 7:

[0021] For the pedal linkage block 9, the pedal linkage block 9 is hingedly mounted on the bottom of the polished rod 5, and can change the angle relative to the polished rod 5. If it is necessary to temporarily disable the device, it is only necessary to rotate the pedal linkage block 9 to make it Leave the piano sustain pedal, rotate the pedal linkage block 9 to get back on the piano sustain pedal, and this machine will continue to function.

[0022] For the polished rod 5, a height adjustment screw 11 for adjusting the height of the pedal linkage block 9 is installed on the polished rod 5. Specifically, the polished rod 5 is sleeved on the bottom protruding shaft of the rectangular frame slider 4, and the height adjustment screw 11 is used to connect the two The other is locked, that is, the height adj...

Abstract

The invention discloses a piano pedal vibration machine, which comprises a metal frame, a rectangular frame slider and a pedal linkage block, a motor is installed on the metal frame, an eccentric wheel is installed on the output end of the motor, and the rectangular frame slider Installed on the metal frame and slidingly matched with the metal frame, the rectangular frame slider is set on the outside of the eccentric wheel, the bottom of the rectangular frame slider is connected with the pedal linkage block through the polished rod, and the motor is electrically connected with the power supply and the switch. The beneficial effect is that the piano pedals are automatically stepped on in an electric way, and it is no longer necessary to manually step on the sustain pedals when adjusting the piano damper, which reduces labor intensity, improves automation, saves manpower, and improves production. efficiency.

Description

technical field [0001] The invention relates to the technical field of piano processing and manufacturing, in particular to a piano pedal vibration machine. Background technique [0002] The piano is a keyboard instrument in Western classical music, and has the reputation of "the king of musical instruments". Consists of 88 keys and a metal string soundboard. The piano range covers almost all the tones in the musical tone system, and is the instrument with the widest range except the organ. The piano is generally used for performances such as solo, ensemble, and accompaniment. It is very convenient for composing and rehearsing music. [0003] During the piano manufacturing process, it is necessary to step on the sustain pedal continuously to adjust the synchronous opening of the piano dampers. In the traditional production process, workers need to continuously step on the sustain pedal with their feet for tens of minutes. This production process is labor-intensive, requi...
