Description
The invention relates in CD-audio player etc., on the dish maintenance face of rotating disk by clamping plate the disk clamp device of holding tray.
This type of device in the past is the function that the face direction that makes the rotating disk side have the function of regulation dish direction of axis line position and confinement plate moves.
Promptly as shown in Figure 5, the teat 4 that the dish that is loaded with dish 2 keeps the center pit of face 3 and cooperation dish 2 is set at rotating disk 1, and with rotating disk 1 and clamping plate 6 clamping disks 2.
Structure in the past like this is because of rotating disk 1 is provided with than the high jut 4 of dish maintenance face 3, so after must making dish 2 coil maintenance face 3 parallel moving relatively earlier, make rotating disk 1 again or coil 2 and move by direction of principal axis.For this reason, need mobile rotating disk 1 or coil 2 mechanism, it is complicated that the structure of device also becomes, and have the mobile space that ensures rotating disk 1 because of having to or coil 2 to make the problem of device maximization.
But, be recorded in the disk clamp device of real public clear 62-3270 communique, be to make the middle part on the rotating disk dented widely, around its recess as the maintenance face of annular disk, in the clamping plate side teat is set, this teat by the center pit of dish, matches with the recess of rotating disk again.So the bottom at teat is provided with the face of cylinder, the center pit of this face of cylinder cooperation dish, the recess of rotating disk.Thus, dish, rotating disk, clamping plate are centered, and guiding face (for example conical surface) is set on limit, the face of cylinder, when the center pit of cooperation dish, be centered close to the center of clamping plate by this guiding face boot disk.
By this structure, dish relatively dish maintenance face is parallel move after, only because of clamping plate near rotating disk, just can finish the work that fills for the rotating disk that coils, move by direction of principal axis and needn't make rotating disk or coil, so simple in structure.Because of guaranteeing the mobile space of rotating disk or dish, on certain program, can make its miniaturization again.
But the face of cylinder that forms in the bottom of teat is because of the gauge of must extend axial length, dish; So the axial dimension of rotating disk and clamping plate can elongate.And, clamping plate is installed on the rotatable parts, again by the turn rotatable parts then the relative rotating disk of clamping plate become from access node structure, structure in view of the above, if during the face of cylinder axial length that the bottom of teat forms one length, with regard to the problem that has teat to be difficult to break away from from the center pit that coils.
Also have, the hole of the turning axle of promising in the heart dress motor in the rotating disk if the axial length in this hole is short, just can not cooperate turning axle deeply; Then the axle center of rotating disk is easily inclined to one side, surface vibration that then can the generation dish.So for the axial length that makes the hole elongates, must be on rotating disk, with the outstanding wheel hub of maintenance face reverse side of dish.The result with regard to had turntable shaft to size more elongated problem.
The objective of the invention is to be to provide a kind of simple in structure, and make rotating disk and clamping plate constitute slimming, to obtain the disk clamp device of miniaturization more.
For achieving the above object, the present invention takes following technical scheme:
Disk clamp device, the dish of its relative rotating disk 11,31 keeps face 12,32 parallel mobile dishes 2, with the rotating disk and and clamping plate 10,40 clampings of configuration relative with dish maintenance face, and with motor rotation driving, it is characterized in that:
Above-mentioned rotating disk does not change its axial position, its ring-shaped depression place 17,37 that has the tubular wheel hub 16,36 that is fixed on motor 13 turning axles and form for the all-moving surface of dish between this wheel hub and dish maintenance face, wheel hub is outstanding unlike dish maintenance face.
Clamping plate has makes above-mentioned dish keep the press section 18 of face holding tray, 41 and insert the annular projection 19 at ring-shaped depression place by the center pit of dish, 42, the peripheral part of this annular projection is matched with the center pit of dish, forbid moving of card direction, the interior perimembranous of this annular projection is connected to the peripheral part of wheel hub mutually simultaneously, and clamping plate and rotating disk are centered.
Described disk clamp device is characterized in that:
Above-mentioned annular projection has the face of cylinder 19d that cooperates center hole in peripheral bottom, 42c, and it is to become the gradually little guiding face 19d of radius, 42a to the top from this face of cylinder.
Described disk clamp device is characterized in that:
Interior perimembranous at annular projection 42 forms conical surface 42b, this conical surface is connected with the peripheral tip edge 36b of above-mentioned tubular wheel hub, and the press section 41 of clamping plate 40 is elastically deformables.
Described disk clamp device is characterized by:
The dish maintenance face of above-mentioned rotating disk adopts flexible material.
Described clamping device is characterized by:
Dish at rotating disk keeps being provided with and will coiling the guiding face 11a of importing dish maintenance face, 31a around the face.
Disk clamp device of the present invention, its rotating disk to the dish all-moving surface not according to moving axially, again at tubular wheel hub that the turning axle be fixed in motor is set on the rotating disk and the ring-shaped depression place between this wheel hub and dish maintenance face; And wheel hub can not be more outstanding than dish maintenance face.On the other hand, clamping plate is provided with press section and annular projection.
Dish is after actual parallel the moving of dish maintenance face, make clamping plate near rotating disk, the center pit of the outside cooperation dish of annular projection, forbid moving of card direction, simultaneously, the inside of annular projection is connected with the outside of wheel hub, carries out centering of clamping plate and rotating disk.
Because of disk clamp device of the present invention, do not exist on the rotating disk than the outstanding part of dish maintenance face, therefore needn't make rotating disk and dish by moving axially, just can insert or the taking-up dish rotating disk.Therefore, simple in structure.The annular projection of clamping plate again, the center pit of its outside cooperation dish, the inner tubular wheel hub that cooperates rotating disk, therefore, also passable even the outside of annular projection is not provided with the face of cylinder.Even be provided with, its axial length also needn't elongate according to the gauge of dish, therefore can shorten the ring jut.So, when the face of cylinder is not set, perhaps shortening the axial length on the face of cylinder, when perhaps supporting clamping plate by rotatable parts, annular projection is easy to break away from from center hole, and simultaneously, rotating disk and clamping plate also can slimmings.
And,,, also can guarantee to cooperate the axial length in the hole of motor rotation axis fully even do not make the outstanding maintenance face opposition side with dish of wheel hub because of the tubular wheel hub protrudes in the inside at ring-shaped depression place.If, even wheel hub outstanding and dish maintenance face opposition side.Because of shortening its overhang, can further dwindle the rotating disk axial length.
Again, the formation on the external bottom end of annular projection cooperates the face of cylinder of center hole; The guiding face that formation is diminished to radius the top of annular projection gradually by the face of cylinder can be forbidden really because of the face of cylinder moving to the card direction.And be easy to the center that boot disk is centered close to clamping plate by guiding face.
Interior perimembranous in annular projection forms the conical surface, and, make the pressing part elastic deformation of clamping plate again of the tip edge linking of this conical surface with the wheel hub periphery, then clamping plate and rotating disk can center accurately, and, can positively remain on dish on the dish maintenance face because of the elasticity of press section.
And for example the maintenance face of fruit tray has at least a part to use as the flexible material of felt etc., then can prevent to pack into or take out the damage that hour indicator writes down when dish.
And the dish that dish is introduced rotating disk keep face near, as the guiding face of taper is set, even dress disk hour indicator keeps moving horizontally relatively with respect to dish maintenance face, can guarantee that also boot disk is to dish maintenance face.
Good effect of the present invention:
As mentioned above, according to the present invention, on rotating disk,,, also can freely adorn dish from the rotating disk there and get even dish is not to moving axially because of not being provided with than the outstanding part of dish maintenance face.Because of rotating disk is constant to the axial location of dish all-moving surface, do not need rotating disk and dish again jointly to moving axially yet, therefore simple in structure.
The annular projection of clamping plate again, perimembranous cooperates the tubular wheel hub of rotating disk in the center pit of its peripheral cooperation dish, so it is also passable that the face of cylinder is not established in the outside of annular projection,, its axial length must just can shorten annular projection than disc thickness size is long even being set.So the face of cylinder is not set, perhaps because of the axial length on the face of cylinder shortens, even clamping plate by the rotatable parts support, annular projection is easy to extract from the center pit of dish, and rotating disk and clamping plate can be done very thinly.
As above, the tubular wheel hub protrudes in the interior perimembranous at ring-shaped depression place, though do not make wheel hub outstanding with dish maintenance face opposition side, also can guarantee to cooperate the axial length in the hole of electric machine rotational axis, thereupon, the axial dimension of rotating disk can be done forr a short time.
Peripheral bottom in annular projection, form the face of cylinder of short cooperation center hole, when the guiding face that the formation radius is gradually little between the front end of annular projection is arrived on the face of cylinder, just can be because of the moving of face of cylinder total ban card direction, and be easy to disk center is guided to the center of clamping plate by guiding face.
Interior perimembranous in annular projection forms the conical surface, this conical surface is connected with the tip edge of wheel hub periphery, and when the press section of clamping plate can elastic deformation,, can guarantee dish because of elasticity again and remain on the dish maintenance face by because of the conical surface can carry out centering of clamping plate and rotating disk accurately.
Just can prevent to coil when adopting soft material such as felt again when at least one fraction of dish maintenance face and adorn the damage of getting the hour indicator record surface.
And near the dish maintenance face of rotating disk during boot disk, as the taper guiding face is set, when dish relatively dish maintenance face move horizontally and when packing into, just can be directed on the maintenance face of coiling by the guarantee dish.
Following with reference to accompanying drawing, describe embodiments of the invention in detail:
Fig. 1 represents the skiagraph of the first embodiment of the present invention.
Fig. 2 represents the outboard profile with embodiment.
Fig. 3 represents the skiagraph of the second embodiment of the present invention.
Fig. 4 represents the ground plan with the clamping plate of embodiment.
Fig. 5 represents the outboard profile of example in the past.
First embodiment illustrated in figures 1 and 2 at first is described.
Fig. 1 is the skiagraph of indicating panel clamping device holding tray 2-state, Fig. 2 be expression clamping plate 10 instead from rotating disk 11, the outboard profile that dish 2 is packed rotating disk 11 states into.
As shown, the dish that forms loading tray 2 on rotating disk 11 keeps face 12 and cooperate the tubular wheel hub 16 of fixed orifice 15 in the turning axle of motor 13, forms ring-shaped depression place 17 between dish maintenance face 12 and the wheel hub 16.The upper end of tubular wheel hub 16, almost with dish maintenance face 12 in one plane, it is outstanding unlike dish maintenance face 12 at least.
Clamping plate 10 is configured in the opposite of dish maintenance face 12.Be formed on the press section 18 of holding tray 2 on the dish maintenance face 12 below the clamping plate 10 and insert the annular projection 19 of above-mentioned recess 17 by coiling 2 center pit 5.
The inboard on the top of annular projection 19 forms the guided inside face 19a of the conical surface, and during near rotating disk 11, the center of clamping plate 10 easily is guided on the center of rotating disk 11 in clamping plate 10.
The top of annular projection 19 outside forms a guiding face 19d to the gradually little conical surface outside of tip radius again, and when the center pit 5 of annular projection 19 insertion dishes 2,2 the center of coiling is directed on the center of clamping plate 10 easily.The inboard of annular projection 19 then forms the inboard face of cylinder 19c that connects inboard guiding face 19a.Not the outer peripheral face 16a that this inboard face of cylinder 19c is cooperated wheel hub 16, to reach rotating disk 11 and clamping plate 10 centers accurately.
In the outside of annular projection 19, form the face of cylinder, the outside 19d that connects external guidance face 19b.Outside face of cylinder 19d, than the gauge of pressing part 18 downward herniated disks 2, and because of the center pit 5 of the face of cylinder, outside 19d cooperation dish 2, dish that can total ban dish 2 keeps the mobile of face direction.Around the dish maintenance face 12, form taper guiding face 11a, in the space of dish maintenance face 12, settle cylindric magnet (iron plate etc.) 20.And columniform alnico magnets 21 are placed in the pressing part 18 of clamping plate 10, make alnico magnets rush at magnet 20, come clamping disk 2 with attractive force between the two.
When above disk clamp device places in this machine of CD projector, be to protect, such as installing by buffer unit for external vibration.Resemble this situation, even because of the relative position between external vibration CD this machine of projector and the disk clamp device changes to some extent, the relative position that the end of the all-moving surface (X-X) of dish 2 is sat between 22 is constant.Therefore, the axial location of the all-moving surface of 11 pairs of dishes 2 of rotating disk is constant.
Above structure because of there be not the part more outstanding than dish maintenance face 12 in rotating disk 11, so rotating disk 11 and dish 2 need not move by axially (Y-Y), just can install on the rotating disk 11 or takes out coiling 2, and structure has just become simply.
Clamping plate 10 again, because of the face of cylinder, outside 10d will cooperation dish 2 center pit 5, inboard face of cylinder 19c will cooperate the tubular wheel hub 16 of rotating disk 11, so the axial length of the face of cylinder, outside 19d does not need than the long (face of cylinder, the outside 19d of the thickness of dish 2, have only a dish half thickness of 2 also passable, perhaps do not establish fully the face of cylinder also can).Thereupon, the total length that can shorten annular projection 19 can be attenuated the gauge of rotating disk 11.So because of the axial length on the inboard face of cylinder short, even clamping plate 10 rotatable parts support also can obtain annular projection from coiling the effect that 2 center pit 5 freely comes off.
Give prominence in the inboard at ring-shaped depression place 17 because of tubular wheel hub 16 again, needn't increase the gauge of rotating disk 11, the turning axle 14 of motor 13 and the hole of wheel hub 16 are cooperated fully longways.
Also has flexible materials such as on the part of dish maintenance face 12, to paste felt at least, to prevent to coil 2 infringements of packing into or taking out the hour indicator record surface.
Below, second embodiment shown in Figure 4 as Fig. 3 is described.
Fig. 3 is the skiagraph of expression with disk clamp device holding tray 1, and Fig. 4 is the ground plan of clamping plate 40.
As shown in these figures, the dish of formation loading tray 2 keeps face 32 and form a ring-shaped depression place 37 between tubular wheel hub 36, two wheel hubs 36 that cooperate fixed orifice 35 on the turning axle 14 of motor 13 and dish maintenance face 32 on rotating disk 31.The upper end of tubular wheel hub 36 almost places on the same surface level with dish maintenance face 32, and is outstanding unlike dish maintenance face at least.
Clamping plate 40 is configured in the opposite of dish maintenance face 32.Formation dish 2 remains in the annular projection 42 of the insertion recess 17 of press section 41 of coiling maintenance face 32 and the center pit 5 that passes through dish 2 below clamping plate 40.
In the outside of annular projection 42, form the taper outside guiding face 42a gradually little to tip radius, following core then forms the conical taper guiding face 42b that sink.Therefore when the tip edge 36b linking of the peripheral 36a of taper guiding face 42b and tubular wheel hub, will center between rotating disk 31 and the clamping plate 40.
Again in the periphery of annular projection 42, form the face of cylinder 42c that connects outside guiding face 42a, can forbid coiling 2 moving again to dish maintenance face direction because of the center pit 5 of face of cylinder 42c cooperation dish 2.
Periphery, bottom in annular projection 42.The equal angles compartment of terrain is provided with three elastic tongue pieces 43 that extend to centrifugal direction.And below the top of each tongue piece 43, pressing part 41 aims at dish maintenance face 32, forms outstanding hemispherical.
According to the 2nd kind of form of implementation, on the effect of first kind of form of implementation, because of the top peripheral edge 36 of taper guiding face 42b and tubular wheel hub 36 is connected the effect that just can obtain to center more accurately between clamping plate 40 and the rotating disk 31.
The press section 41 again, be dish 2 to be pressed into dish maintenance face 32 with the elasticity of elastic tongue piece 43, therefore, even, also can remain on dish 2 on the dish maintenance face 32 compared with the gauge of dish 2 difference more or less.
And for this form of implementation, the peripheral tip edge 36b of tubular wheel hub forms taper and also can.
