Abstract
A musical box features that its bottom plate is formed by combining two parts into a whole. Its primary bottom plate, spring casing, supporters of speed regulator and sound drum bearing, and fixing seat of partial sound plate are made into a whole part by injection. Its partial bottom plate and the supporters of bearings in gear driving axles system are made into another whole by injection. They are combined together by ultrasonic welding of plastics. Its advantages include use of plastics instead of aluminium, high integrated level and low cost.
Description
The present invention relates to musical box, is the global design scheme of a kind of novelty of musical box.
The base plate of musical box forms so that Al-alloy metal is molded traditionally, Heavy Weight, material and manufacturing cost height.Main members such as the base plate of tradition musical box, clockwork spring shell, speed-regulating rack all are the branch body structures, must rivet, and the change expense is more in the man-hour of fit in the process of making musical box, so manufacturing cost is than higher.
The objective of the invention is to improve the integrated degree of musical box each parts in manufacture process, thereby improve each part assembly precision each other, when reducing the millwright in the manufacture process, reduce the manufacturing cost of whole musical box.
Another object of the present invention is in order to realize with the plastics substituting metal, the material cost of musical box to be reduced.
A further object of the present invention is will remedy to mould the musical box tonequality of being caused for aluminium to descend, and makes musical box still can keep original tonequality.
Task of the present invention is finished like this:
At first be originally respectively independently base plate, clockwork spring shell, speed regulator support three set become the aggregate of " trinity ", it all be that the job operation of plastics matter, employing plastics single injection-molded is made as a part.
Next is with the clockwork spring winding mechanism, and transmission gear train and speed regulator and speed governing axle and the set of local base plate are assembled into one.Local base plate is the part of above-mentioned musical box monoblock base plate, it with above-mentioned unsplit bed(-)plate on a vacancy contraposition mutually, just formed a complete full-plastic musical movements baseboard after being mutually permanently connected when the two is chimeric.The part and the sounding drum bearing bridge that include clockwork spring shell plastics matter and its integrated injection molding, speed regulator support, soundboard holder on the described main body base plate.The bearing bridge that includes confession transmission gear train bearings plastics matter and its integrated injection molding on the described local base plate.Like this, realize whole plastics of musical movements baseboard, clockwork spring shell, speed regulator support and each bearing bracket stand, saved aluminium widely.
Its three, adopt with mould for after the scheme of aluminium because the soundboard holder that is positioned on the base plate has also become plastics matter, the shortening of lingering sound time made both poor sound quality when this can cause the soundboard vibration.In order to prevent this point, the present invention has adopted and has allowed the connecting screw of soundboard holder and screw just in time be positioned at scheme on this metal abaculus, and there is the hollow part described metal abaculus inside, and the lingering sound time of pronunciation increases when making the soundboard vibration, and tonequality improves.
Advantage of the present invention at first is that being integrated of musical box parts makes processing, assembling saving of work and time, reduced the manufacturing cost of musical box; Secondly the present invention adopts to mould for aluminium, and making the part of base plate, clockwork spring shell, speed regulator support, bearing bridge, the soundboard holder of musical box all adopt plastics basically is that material is made, and has reduced material cost, has improved manufacturing accuracy and production efficiency; Moreover, make musical box in whole manufacturing assembling process, can adopt the disposable ultrasonic soldering of many solder joints and eliminate riveted joint, improved production efficiency.
Below in conjunction with embodiment and accompanying drawing the present invention is described in detail.

Fig. 4 is the assembled relation stereographic map of Fig. 2 and Fig. 3 two partial component.
Fig. 5 is the overall stereographic map that each parts of present embodiment are finished the musical box product of overall assembling back formation.
Fig. 6 is Fig. 2 half-twist and finishes the later three-dimensional view of partial assembled.
Fig. 7 is the three-dimensional view of reflection main body base plate and local base plate assembly relation.
Musical box of the present invention includes overall plastic main body base plate (1) and local overall plastic base plate (2), on main body base plate (1), leave an edge profile and the corresponding to vacancy of local base plate (2) edge contour (3), after the two is chimeric, form a complete overall plastic base plate, it includes base plate position plastics matter clockwork spring shell (4) thereon itself, the bearing bridge of plastics matter speed regulator support (5) and each plastics matter.The holder of soundboard is made up of two parts, and its part is plastics matter (8 '), and it and main floor (1) are integrally formed, and another part is hollow metal matter (8), the two side by side, chimeric mutually, be fixed on base plate (1) and go up (see figure 2).The soundboard (6) of vibration pronunciation is to be fixed on the metallic holder (8 ') by gib screw (7), (7 ').Metal matter holder (8) inside is hollow, can prolong the lingering sound time of soundboard pronunciation like this, makes tone quality improving.
Bearing (10) and bearing bridge working of plastics such as (11) with the clockwork spring shell (4) of its integrated injection molding, speed regulator support (5), soundboard holder (8 '), sounding drum (9) are arranged on main body base plate (1).Wherein clockwork spring shell (4) and speed regulator support (5) the two be conjoined structure.Sounding drum bearing (10) is fixed as one with ultrasonic soldering with bearing bridge (11).
Plastics matter bearing bridge (17), (17 '), (18), (18 ') in order to the fixed gear train are arranged, they and local base plate (2) integral molded plastic moulding on local base plate (2).Described gear drive train includes by the order of its power transmission: sounding drum mill pinlon (12), gap bridge pagoda gear (13), shaft gear (19), worm gear (14).Wherein said mill pinlon (12) is accepted the power from clockwork spring, and the worm screw (16) that worm gear (14) then is responsible for power finally is transferred to speed regulator (5) gets on.Bearing bridge (17), (17 ') are used to support described gap bridge pagoda gear (13), and bearing bridge (18), (18 ') then are used to support worm gear (14) and shaft gear (19).Clockwork spring assembly (20) is fixed on respectively on the medium pore (23) of the medium pore (22) of clockwork spring shell (4) end face and local base plate (2) by winder (21).Governor assembly (15) then is fixed in the interior survey axis hole (25) and the speed governing axis hole (24) on the local base plate (2) of speed regulator support (5) by governor shaft (worm shaft) (16).
Final stage is being installed as long as corresponding vacancy (3) contraposition with main body base plate (1) that local base plate (2) is bottom-up embeds, is making pile crown (26) on the main body base plate (1) and (27) insert respectively that local base plate (2) is gone up corresponding stake hole (28), (29) are interior can make the two be combined as a whole with ultrasonic soldering.Sound drum bearing (10) is to carry out simultaneously with the Plastic Welding of stake hole (28), (29) with above-mentioned two pile crowns (26), (27) with support (11) Plastic Welding each other, also have, main body base plate (1) and local base plate (2) binding face each other be connected the edge and also be welded into one simultaneously.
Protection scope of the present invention is not limited to scope of disclosure among the embodiment, such as makes the composite bottom board of plastics matter into metallic composite bottom board, and this simple material change still belongs to protection scope of the present invention.
