Automatic grinding method and device for tablet of music box

Abstract

The invention discloses an automatic grinding method for a tablet of a music box. The tablet is ground through a grinding tool, the grinding amount of the tablet starts to be counted when a detector detects that the tablet makes contact with the grinding tool, and then grinding is conducted till the set amount. The invention accordingly provides an automatic grinding device for the tablet of the music box. The automatic grinding device comprises a clamping mechanism, a grinding mechanism, a controller and a sonar sensor. The tablet is clamped by the clamping mechanism, the grinding mechanism drives a grinding wheel to act, the grinding mechanism is controlled by the controller to act, the sonar sensor detects whether the tablet makes contact with the grinding wheel or not and sends out a contact signal to the controller. The controller starts to count the grinding amount after receiving the contact signal and stops the grinding mechanism till the grinding amount reaches the set grinding amount. The automatic grinding method and the automatic grinding device have the beneficial effects that the adopted judgment method that whether the tablet makes contact with the grinding wheel or not is detected through the sonar sensor is higher in precision; the grinding amount can be accurately controlled, and the grinding precision can be improved; and the frequency of the tablet can be more accurately adjusted.

Description

technical field [0001] The invention relates to a method and equipment for processing octave sound pieces, in particular to a method and a device for grinding the sound keys of sound pieces. Background technique [0002] The sound piece in the octave refers to the pronunciation parts of the octave, also known as tuning forks, soundboards, etc., which include multiple or multiple keys. When making a sound sheet, it is necessary to ensure that the sound keys of the sound sheet emit standard sounds through the quality of each key on the sound sheet. However, in mechanical processing, the pre-processed sound pieces often cannot meet the standard pronunciation. Therefore, it is necessary to adjust the sound wave frequency when the key vibrates. The conventional frequency modulation method adopts manual operation: the worker holds the electric grinding head in one hand, and the other Hold the pick with only one hand and grind with an electric grinding head. Manual frequency modu...

AI Technical Summary

Problems solved by technology

Manual frequency modulation operation requires the operator to have good operation skills, labor intensity is high, and there are great safety hazards during operation

There is also an electrolytic method for frequency modulation of the octave sound pieces. The method is to place the sound pieces in the electrolyte for electrolysis, and use the electrolytic method to slightly change the quality of the sound pieces. This method also has some defects: electrolysis The electrolytic head is fixed during FM, and only the root of the sound film can be electrolyzed. When the root of the sound film is electrolyzed too much, the head material of the sound film cannot be electrolyzed to tune the frequency
