Description
Technical field
The present invention relates to a kind of pianos to assemble field devices, especially a kind of for correcting the device and saddle of piano saddle
With the assembly method of soundboard.
Background technique
Piano sympathetic response disk is made of backrest, soundboard, iron plate, saddle chord column, is the core component of piano.Saddle is sympathetic response
The important composition part of disk, is mounted on the soundboard of piano.The effect of saddle is the energy transmission Chord vibration to soundboard, and is risen
Beautify the effect of sound quality.The saddle of upright piano is divided into bass and Hi-Mid two.The saddle of semi-machine semi-hand at present is processed
Process is 1. to process saddle panel with electric hand planer, digs saddle height, the low arch bridge in substantially intermediate high both ends by design requirement
Shape；2. saddle nail hole is imprinted on saddle panel using positioning hole tool, then saddle is placed on special drill press and has been installed
Inclined tooling supporting plate on carefully carefully drill out flat nail hole；3. Manual shovel slope：Using dedicated on the basis of the line of soundboard hole
Cutter shovels out the groove that slot bottom is radian outward and 4. squeezes into saddle nail by hand；5. saddle is mounted in soundboard according to positioning tool
On.It can be seen that the processing technology of saddle requires to be very high, it is a complexity, process careful, precision is high, therefore
Saddle manufacturing procedure is decided to be one " critical process " of piano production.
But the process, due to technical requirements height, large labor intensity hand-manipulated is easy to appear quality fluctuation, and processes
Process can generate certain noise and dust, and working environment is poor.According to the design requirement of sympathetic response disk, have between saddle and iron plate
Multiple spot accurately differential requirement, because the casting technique of iron plate determines whether the size of iron plate will appear subtle, unstable change
Change, in order to correct these variations, the method for generalling use adjustment iron plate height is remedied, but the rigidity of iron plate is very big, can
Adjust space it is limited, so, even if having found between saddle and iron plate it is existing it is differential do not meet design requirement, also can not be to saddle
Secondary operation is carried out to be allowed to meet drawing size.Here it is the maximum puzzlements that traditional saddle processing technology causes fit on.
The patent of invention of Patent No. 201310426061.X discloses a kind of device for correcting piano saddle and saddle and soundboard
Assembly method, wherein described device includes workbench and sets multiple clamp systems on the table, each clamp system
Including fixed mandril, flexible mandril and telescoping mechanism, wherein flexible mandril is connect with telescoping mechanism；In multiple clamp systems
