Perforative pit slot, upper hand hole are connected to pit slot, and item is set in pit slot and upper hand hole；Middle seat board uses clamping plate.
As a preferred embodiment, in overlook direction, the front of wood key is rectangle, and the middle part and rear portion of wood key are at always
Line, and the middle part of wood key and front rake.
As a preferred embodiment, the middle part of wood key and rear portion shape are integral, the left side and right side of the entirety are flat
Face.
As a preferred embodiment, tab is rectangle, it is attached on the upper surface of wood key front；Spline is irregular cube, patch
On the upper surface of wood key front.
As a preferred embodiment, tab is white key piece, spline is black key item.
As a preferred embodiment, middle seat board is monoblock clamping plate, the left side and right side of middle seat board respectively with the middle part of wood key
Left side and right side alignment, the leading flank of middle seat board and trailing flank are parallel with the front end face of wood key.
As a preferred embodiment, clamping plate is multilayer composite sheet and is squeezed by super glue, there is high-strength deformation-resistant energy
Power.
As a preferred embodiment, the stacking direction of multilayer composite sheet is upper and lower directions.
As a preferred embodiment, upper hand hole is strip-shaped hole；The quantity of pit slot is two.
As a preferred embodiment, the length of upper hand hole is 12-13mm, width 5-6mm；The width of pit slot is 10-11mm, high
Degree is 2-3mm；The thickness of clamping plate is 5.5-6.5mm.
Generally speaking, the invention has the advantages that：
1. under the premise of not influencing key overall quality, middle seat board uses clamping plate, and clamping plate deflection is small, affected by environment
It is small, while impact resistance is indeformable, is conducive to mechanical processing so that machinery, which is worn, to be possibly realized, and is that the semi-mechanization of parts produces
Possibility is provided, production efficiency is improved.
2. overall structure is smooth, it is easy to clamping.
3. overall structure is smooth, cut off conducive to rear machinery is worn.
4. after mechanical processing, key quality is more secure.
Description of the drawings
Fig. 1 is the front view of present invention patch tab.
Fig. 2 is the vertical view of present invention patch tab.
Fig. 3 is the front view of present invention patch spline.
Fig. 4 is the vertical view of present invention patch spline.
Wherein, 1 is wood key, and 2 be tab, and 3 be middle seat board, and 4 be upper hand hole, and 5 be pit slot, and 6 be item, and 7 be spline.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
It can be used for machining piano key of item, including wood key, tab/spline, middle seat board.Paste key in the front of wood key
The middle part top of piece/spline, wood key is equipped with middle seat board；The upper end of middle seat board is provided with hand hole, and the side of middle seat board is provided with left and right
Perforative pit slot, upper hand hole are connected to pit slot, and item is set in pit slot and upper hand hole；Middle seat board uses clamping plate.
In overlook direction, the front of wood key is rectangle, the middle part and rear portion of wood key in line, and the middle part of wood key
With front rake；The wood key for posting tab, from the middle part front end of wood key to the rear portion rear end of wood key, on the left and right directions of wood key
Width (i.e. the width of upper and lower directions in Fig. 2) tapers into.The middle part of wood key and rear portion shape are integral, the left side of the entirety
It is plane with right side.
Tab is rectangle, is attached on the upper surface of wood key front；Spline is irregular cube, is attached to the upper of wood key front
