Description
Technical field
The utility model relates to the assembly tool of piano parts, specifically, relates to the assembling jig that the piano adopted in a kind of semi-automatic process regulates frequency modulator.
Background technology
Piano adjustment frequency modulator is the parts of piano, and as depicted in figs. 1 and 2, it comprises adjustment shelves, adjusting knob and adjusting knob screw.Regulate shelves to be xsects be the elongated batten of rectangle, along the length direction regulating shelves, it evenly has multiple through hole shape mounting hole be arranged in rows.The afterbody of adjusting knob screw is circular, and after head is passed down through and regulates shelves, adjusting knob screws in the head of adjusting knob screw, completes the assembling regulating frequency modulator.
A piano has maximum four groups to regulate frequency modulator, corresponding high pitch, alto, middle pitch and bass respectively.Adjustment shelves size and the mounting hole spacing of different adjustment frequency modulator are slightly distinguished.
Prior art adopts manual installation, is screwed in mounting hole by adjusting knob screw one by one, then screws adjusting knob.Due to adjusting knob and adjusting knob screw number many, and size is little, and installation is wasted time and energy.
Utility model content
For the technical matters existed in prior art, the purpose of this utility model is: providing a kind of will be the assembling jig that the piano regulating the semi-automatic assembling of frequency modulator to prepare regulates frequency modulator in shallow for adjusting knob screw insertion mounting hole.
In order to achieve the above object, the utility model adopts following technical scheme:
Piano regulates the assembling jig of frequency modulator, regulates frequency modulator to comprise and regulates shelves and multiple adjusting knob screw, and adjusting knob screw loads in the multiple mounting holes regulating and shelves are arranged in rows; Piano regulates the assembling jig of frequency modulator to comprise base plate, fixed half and moving half; Cover half is fixed on base plate, and dynamic model to be arranged on base plate with cover half split by rotation section or to be separated; When dynamic model turns to cover half split, dynamic model, surround clamping between cover half and base plate and regulate the cavity volume of shelves, between dynamic model and cover half, surround many installation passages passed for adjusting knob screws, passage is installed and mounting hole just right one by one.
Fixed half and moving half is run through in cavity volume one end in the longitudinal direction, and the other end is be arranged on the locating piece in cover half or dynamic model.
The ratio of cavity volume in fixed half and moving half is one to one, and installing the ratio of passage in fixed half and moving half is one to one.
Cover half is fixed on base plate by the screw that many are alongst evenly arranged.
The xsect of cavity volume is rectangle, installs channel vertical in the upper surface of cavity volume.
Fixed half and moving half plating zinc on surface.
One end of dynamic model is semicircle, and rotation section is the rotating shaft being positioned at the semicircular center of circle.
Shelves are regulated to be divided into high pitch to regulate shelves, alto to regulate shelves, middle pitch to regulate shelves and bass to regulate shelves; The quantity of cover half is three, is high pitch cover half, alto and middle pitch cover half, bass cover half respectively; The quantity of dynamic model is two, is high pitch and alto dynamic model, middle pitch and bass dynamic model respectively; High pitch cover half, high pitch and alto dynamic model, alto and middle pitch cover half, middle pitch and bass dynamic model, bass cover half set gradually; High pitch and alto dynamic model swing at high pitch cover half and between alto and middle pitch cover half, one of them swings extreme position is high pitch cover half with high pitch and the split of alto dynamic model and surrounds and clamp the cavity volume that high pitch regulates shelves, and another swing extreme position is that alto and middle pitch cover half and high pitch and alto dynamic model surround and clamp the cavity volume that alto regulates shelves; Middle pitch and bass dynamic model swing at alto with between middle pitch cover half and bass cover half, one of them swings extreme position is that middle pitch and bass dynamic model surround and clamp with alto and the split of middle pitch cover half the cavity volume that middle pitch regulates shelves, and another swing extreme position is bass cover half and middle pitch and the split of bass dynamic model and surrounds to clamp the cavity volume that bass regulates shelves.
The rotation section of high pitch and alto dynamic model, middle pitch and bass dynamic model is all in the same side.
During split, align away from one end of rotation section with middle pitch and bass dynamic model in one end of bass cover half, middle pitch and bass dynamic model align with one end of alto and middle pitch cover half away from one end of rotation section, align away from one end of rotation section with high pitch and alto dynamic model in one end of alto and middle pitch cover half, high pitch and alto dynamic model align with one end of high pitch cover half away from one end of rotation section.
Principle of the present utility model is:
By the cooperation of cover half, dynamic model and base plate, shelves will be regulated to clamp, cavity volume will regulate shelves to locate, and make to regulate the mounting hole of shelves just to the installation passage be made up of fixed half and moving half; Through installing the guiding of passage, adjusting knob screw is inserted and is installed in passage also just to mounting hole.After regulating all adjusting knob screw placement of shelves correspondences by one, beat the afterbody of adjusting knob screw gently with instrument, make the head of adjusting knob screw simple enter mounting hole, for the follow-up adjusting knob screw step that automatically screws is prepared.Rotate dynamic model, can folding cavity volume.
A piano has at most four groups to regulate frequency modulator, regulates the fixed half and moving half of frequency modulator to be integrated on an assembling jig by four groups, by rotating dynamic model, dynamic model and different cover half splits, can assemble the corresponding shelves that regulate.The adjustment mark structure that two sides of a dynamic model are corresponding different, a rotary type dynamic model can be used as two dynamic models and uses.
Generally speaking, the utility model tool has the following advantages:
1., owing to there being the guiding of installing passage, in the loading mounting hole that adjusting knob screw can be vertical, avoid cannot installing because adjusting knob screw tilts in follow-up automatic assembling process.
2. after beaing with instrument, the afterbody annulus of adjusting knob screw withstands the upper surface of fixed half and moving half, and the length of installing passage determines the insertion depth of adjusting knob screw, and after installing, the insertion depth of each adjusting knob screw is unified
3. installation process is simple and quick, prepares for subsequent mechanical is torqued into adjusting knob screw.
4. swing any collocation that dynamic model can realize dynamic model and adjacent two pieces of cover half, swift to operate, dual-use material simultaneously, reduces the volume of assembling jig.
5. the assembling that a piano 3--4 group regulates frequency modulator taken into account by an assembling jig, and highly versatile, can be applicable to the piano of all models.
