Abstract
The invention discloses a manual guide rail type trimmable piano tuner with scale mark. A fixed rail of a guide rail is connected with a string code which needs to be tuned through an inner octagonal piano driving end, and a tuning peg can be adjusted coaxially; a supporting sleeve on a movable rail of the guide rail is connected with the other string code for playing a role of supporting, wherein a main shaft with scale mark slot is provided with a two-direction brake; and the brake can position and brake a taut string and a slack string. The guide rail type trimmable piano tuner solves the problem of quantization control of a rotated angle, and has the stable torque force, abandons the traditional tuning mode of over pulling back, and can be stably controlled. Coaxial torque output is adopted at an adjusting end of the string code, so that the defects that a string shaft deforms and dispositional damage is caused because a traditional wrench acts on the string shaft to stress unilaterally can be overcome. The guide rail type trimmable piano tuner has the advantages of simple operation, labor saving, stable control, high accuracy and no deformation of the string shaft after the piano is tuned, and is a tool special for a professional tuner and a tuning enthusiast to further improve tuning accuracy.
Description
Technical field
The present invention relates to piano and peg musical instrument technical field is arranged, the tuning instrument that fine adjustment type piano organ stop specifically is made up of main shaft, two angles positioning stop, arm of force guide rail four parts of planet wheel reinforcement structure, band indexing trough.
Background technology
What traditional piano organ stop adopted is " L " type tuning spanner; It is a kind of monolateral lever augmented structure of exerting oneself; Which kind of tuning action is this structural design defective cause no matter adopting; All the time exist peg harmful shearing and moment of flexure are existed, the careless slightly string axis hole that will cause is out of shape, and string sign indicating number grip is descended.Because this structure right and wrong rotate with unbalanced shaft, angle out of strength is different, when rotating spanner, is engraved in variation during friction force between string axle and the string sign indicating number, also is to control one of difficult problem for the professional.Because above-mentioned situation exists, string axle elastic deformation is inevitably, in piano design flexibility modification amount allowed band; Can rely on the string axial stress to give equilibrium point for change; The tuning gimmick is harmonized " to draw high readjustment " through the tuner, if exceed deflection, can cause the string shaft distortion; Grip descends, and directly influences the life-span of string axle.To sum up, tradition " L " type spanner, though simple in structure, big, the effort of operation easier, wayward, degree of regulation and accuracy in pitch stability are difficult to guarantee.
Summary of the invention
The purpose of this invention is to provide a kind of guide tracked fine-tuning piano organ stop, characteristics are that simple to operate, laborsaving, control stabilization, tuning precision are high, peg does not have distortion after the tuning.In use, can realize the control of calibration continuous fine adjustment.Be fit to piano tuning duty dealer and tuning fan and can both conveniently use piano tuning instrument.
For realizing above-mentioned purpose, design a kind of organ stop, its composition comprises planetary gear construction, the main shaft of being with indexing trough, two angles positioning stop, reaches parts such as arm of force guide rail, stop sleeve, handwheel.It is characterized in that: main regulation parts concentric shafts such as the main shaft of anistree piano driving end, main shaft, epicyclic gearbox, band indexing trough, handwheel connect in comprising; And be fixed on the guide rail orbit determination; Two angles positioning stop is through being bolted on the corresponding pilot hole of epicyclic gearbox; Two angles positioning stop is that rotate at the center with the fixed pivot, and left and right sides drift angle is also realized the location through magnetic attraction and the main shaft interlock of being with indexing trough, and can realize positive and negative both direction control; Wherein for obtaining magnetic attraction; Two angles positioning stop is made up of cast iron materials and permanent magnetism rigid material respectively with the main shaft of band indexing trough, or permanent magnetism rigid material and cast iron materials composition, or the magnetic material that attracts each other is formed.Moving rail one end of guide rail is fixed through bolt and stop sleeve, and band of column structural design prevents landing, slides as required, finds suitable fulcrum.
Bi-directional braking calibration fine setting detent mechanism comprises two parts of main shaft of two angles positioning stop and band indexing trough, and the every circumference of main shaft of band indexing trough is evenly distributed 50 location lobes.Two angles limit the direction of motion of loose string and tight string respectively about the positioning stop of two angles.
The planetary gear construction speed ratio is 1: 99, has the high characteristics that are fit to heavy load power of precision, through this structure deceleration force amplifier.
The torque ratio of handwheel and string sign indicating number 1: 5.
The moving orientation angle of revolution (360 °/50=7.2 °) fine adjustment type piano organ stop driving end angle of rotation
φ＝360°/50/99＝0.072°
According to high pitch to bass string Tension Moment mean value is that 120kgcm calculates the rotating torque f=120/99/5=0.24kgcm (string agate and peg friction force are not calculated) that guide tracked fine-tuning piano organ stop handle is required.
In main shaft, handwheel and the epicyclic gearbox main shaft concentric shafts draw bail of anistree piano driving end, band indexing trough design, its power that acts on the piano string sign indicating number is concentric revolving force, no side direction is to the string axial pressure.
The present invention compares with prior art that the tuning precision is high, control stabilization is accurate, laborsaving, peg does not have the distortion advantage, is suitable for the specific purpose tool of professional tuner's accurate adjustment, also is fit to the tuning fan, and with reference to tone correcting device, tuning software combines the present invention, reaches professional level.Light and handy, the non-maintaining utilization that is worthy to be popularized of structure.
