Drilling mechanism used for piano manufacturing

Abstract

The invention relates to the technical field of piano processing drilling, in particular to a drilling mechanism used for piano manufacturing. The drilling mechanism used for piano manufacturing comprises a supporting seat, wherein a rotating shaft is rotatably connected with the center of the top of the supporting seat, the bottom end of the rotating shaft penetrates through the top of the supporting seat, extends to be below the supporting seat, and is connected with a grooved wheel positioning mechanism, the top of the rotating shaft is fixedly connected with a rotating disc, multiple fan-shaped blocks are rotatably connected with the side face of the rotating disc, rectangular grooves are formed in the sides, away from the rotating disc, of all the fan-shaped blocks, square rods are fixedly connected with the interiors of all the rectangular grooves, and two corresponding placing blocks are inserted into each square rod. According to the technical scheme, hammer head wooden core main bodies are placed in grooves between the placing blocks, so that the probability of deformation damage, to the hammer head wooden core main bodies, caused by force application clamping is reduced, thus the completeness of the hammer head wooden core main bodies is improved, and improvement of the effect that hammer heads knock strings to make sounds is facilitated.

Description

technical field [0001] The invention relates to the field of drilling holes for piano processing, in particular to a drilling mechanism for making pianos. Background technique [0002] Piano hammers are the parts that strike the strings to produce sound. The hammers on the piano are divided into bass hammers, alto hammers and treble hammers. The holes of the treble hammers are straight holes, and the angles of the holes on the bass hammers One side of the hammer core and at a fixed angle, for tenor hammers the holes are angled to the other side of the hammer core. [0003] Some patent documents related to piano hammer drilling are disclosed in the prior art. The Chinese patent application number CN201310236750.4 discloses an automatic drilling machine for piano alto hammers and a drilling processing method. The drilling mechanism includes A plurality of drilling devices, these drilling devices are arranged in a row along the horizontal direction and fixed on the mobile pane...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, in the process of drilling the hammer core, the hammer core needs to be limited and clamped. In the prior art, the hammer core is mostly clamped on the side and the top by the cylinder. It is a part used for sounding the strings. It has extremely high requirements for the quality of the hammer core, and the hammer core is made of wood, which is very easy to be damaged. It is difficult to control the hammer core by pushing it through the cylinder. The pressure of the cylinder easily deforms the hammer wood core during the clamping process, resulting in damage to the hammer wood core, which affects the sound effect of the strings during actual installation
