A drilling mechanism for piano making

Abstract

The invention relates to the technical field of piano processing and drilling, in particular to a drilling mechanism for piano production, which includes a support seat, a rotating shaft is rotatably connected to the center of the top of the support seat, and the bottom end of the rotating shaft passes through the top of the support seat and extends to A sheave positioning mechanism is connected under the support seat, a rotating disk is fixedly connected to the top of the rotating shaft, and a plurality of fan-shaped blocks are connected to the side of the rotating disk, and the side of the fan-shaped blocks away from the rotating disk is provided with a rectangular groove, and the rectangular grooves are fixed A square rod is connected, and two placement blocks are inserted on each of the square rods; this technical solution places the main body of the hammer wood core in the groove between the placement blocks, reducing the force clamping on the main body of the hammer wood core. The probability of deformation damage is improved, thereby improving the integrity of the main body of the hammer core, which is conducive to improving the sound effect of the hammer hitting the strings.

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
