Problems solved by technology

When the traditional soundboard ribs are assembled with each other, the pre-processed soundboard and the ribs are glued together, and then clamped and pressed by clamps, clamps, etc., solidified, and shaped. This gluing method often makes the ribs The arrangement of the strips on the soundboard is not even enough, and the uneven pressure will easily lead to the glue between the ribs and the soundboard, which will affect the sound and bearing capacity of the soundboard

Embodiment 1

[0040] An installation device for piano soundboard ribs, as attached figure 1 and attached figure 2 As shown, a rectangular bearing platform 1 is included, and the bearing platform 1 has a concave inner ring 11, and the inner ring 11 is also rectangular. In addition, the inner ring 11 is provided with a limit plate 2, the limit plate 2 is provided with a plurality of elongated clamping holes 21, and all the clamping holes 21 are parallel to one of the diagonal lines of the limit plate 2 The setting, the specific setting of the card hole 21 can also be adjusted according to the actual requirements of the piano soundboard 8 . The limiting plate 2 is provided with a plurality of positioning screws 22 symmetrically about the center. Here, the positioning screws 22 are located on the other diagonal of the limiting plate 2 near the corresponding diagonal, and the positioning screws 22 are formed L-shaped, and a positioning screw hole 13 corresponding to the positioning screw 22 i...

Embodiment 2

[0046] An installation device for piano soundboard ribs, as attached Figure 4 As shown, based on the first embodiment, the lower surface of the pressure arm 4 is provided with an airbag 6 , the airbag 6 is arranged along the length direction of the pressure arm 4 , and the airbag 6 is slightly longer than the pressure arm 4 . Here, the airbag 6 and the lower surface of the pressure arm 4 are directly glued together. Alternatively, the airbag 6 and the pressure arm 4 can also be bound together by ribbons, etc., which can be determined according to the actual situation. In addition, the airbag 6 is in a tubular shape after inflation, and one end of the airbag 6 is connected to an air valve 61 through a trachea, and the air valve 61 is located on the side of the pressure arm 4 .

[0047] After the pressure arm 4 is pressed on the limit plate 2 and the buckle 5 is buckled on the pressure arm 4, the staff can use the air compressor to inflate the airbag 6 through the air valve 61...

Embodiment 3

[0050] An installation device for piano soundboard ribs, based on the second embodiment, one pair of side center points of the bearing platform 1 is hinged on a frame 7 , and the bearing platform 1 can be turned over on the frame 7 . On the other hand, the two planes of the carrying table 1 are provided with the inner ring 11 , and the clamping holes 21 of the two limit plates 2 on the two planes are respectively arranged along two diagonal lines which are relatively symmetrical. At the same time, the two planes of the bearing platform 1 are provided with pressure arms 4, and the pressure arms 4 are also arranged in parallel with the clamping holes 21 of the limiting plates 2 on both sides respectively. Furthermore, one side surface of the carrying platform 1 is provided with a latch hole 14 near the position where it is hinged with the frame 7 , and the frame 7 is provided with a positioning pin 71 . When the bearing platform 1 is stable, the positioning pins 71 can be rotate...

Abstract

A new type of installation device for piano soundboard rib wood, comprising a bearing platform with a limit plate on the bearing platform, the limit plate is provided with clamping holes for rib wood strips to pass through at equal intervals, and a pressure corresponding to the clamping holes is provided on the bearing platform The arm, the pressure arm is hinged with the hinged arm fixed on the bearing platform, and the top of the hinged arm is connected with the upper surface of the pressure arm through an elastic piece. By adopting the above technical solution, the limit plate is used to distribute the ribs evenly, and then the pressure arm applies pressure to the ribs one by one, which ensures that each rib can be subjected to sufficient pressure, thereby reducing the occurrence of degumming between the ribs and the soundboard. Problems, and when the pressure arm is swung up, the elastic member can pull back the pressure arm, so that the labor of the staff can be reduced.

Description

technical field [0001] The invention relates to the field of piano production, in particular to a new type of installation device for piano soundboard ribs. Background technique [0002] The piano soundboard is composed of resonance plate, rib, string code, soundboard frame and other components. For sound continuity, the soundboard must be curved. Its concave surface is glued with ribs, and its convex surface is equipped with chords. [0003] The rib is an indispensable part of the soundboard. It bears a large tensile stress in the soundboard. The two ends of the rib are designed as oblique diamonds, and the bonding surface with the resonance plate is designed as a slightly convex arc. [0004] Ribs can strengthen the resonance plate and resist the pressure from the string yard. Due to the different propagation speeds of sound waves in the wood along the growth rings and across the growth rings, the sound wave vibrations pass through any point on the string yard and trave...
