Embodiment
Shown in Fig. 1 to 4, the utility model relates to a kind of bridge clamping plate 1 or base plate 31 of the watch and clock movement for clock and watch.Yet obviously, the utility model also is applicable to base plate and at least one bridge clamping plate of described movement.
Advantageously, bridge clamping plate 1 and/or base plate 31 are formed by sintered ceramic, make precision that its plate 9,39 is given security and functional.Above-mentioned sintered ceramic for example can be aluminium oxide or zirconia-based ceramics, silicon nitride or nitrogenize titanium-base ceramics or titanium carbide base pottery.
Preferably, in the example shown in Fig. 2 and Fig. 4, watch and clock movement comprises three stationary installations 2,4,6, and described stationary installation 2,4,6 is intended to via screw bridge clamping plate 1 are fixed on the base plate 31.Therefore, each stationary installation 2,4,6 has hole 11 in bridge clamping plate 1 and screw in known manner, and this screw is intended to be rotatably assorted with thread groove 41 in base plate 31.Advantageously, according to the utility model, the hole 11 in bridge clamping plate 1 has two different pieces, and these two different pieces form the shoulder 13 that is intended to serve as for the retainer of the head of screw, with after being screwed in operation bridge clamping plate 1 are remained against on the base plate 31.
Preferably, above-mentioned coating 15 can comprise gold, copper, nickel, NiP alloy, TiW alloy or AuCr alloy in nonrestrictive mode.Coating 15 can be formed on the shoulder 13 for example at least 5 microns with certain thickness by for example vapour deposition process (as cathodic sputtering).
Each stationary installation 2,4,6 also can be included in mortise 12 and tenon 42 assemblies between at least one bridge clamping plate 1 and the base plate 3, in order to before fixing described bridge clamping plate and base plate they are correctly located.In the example shown in Fig. 2, as can be seen, stationary installation 4 comprises the blind hole 12 that forms mortise, and this mortise is intended to cooperate with the tenon 42 of base plate 31.
Preferably, in the example shown in Fig. 1 to Fig. 4, bridge clamping plate 1 and/or base plate 31 also comprise at least one supporting base 8,10,36,38,40, and described supporting base is intended to carry the pivot of at least one element of described watch and clock movement.
Advantageously, according to the utility model, described at least one supporting base 8,10,36,38,40 and bridge clamping plate 1 and/or base plate 31 make one, that is, do not use any jewel.Therefore each supporting base 8,10,36,38,40 can comprise the hole 17,47 that forms the jewel supporting base, that is, and and the slidingsurface of the rotation of hole 17,47 wall 19, one of them described pivot that 49 usefulness act on described element.
Preferably, if the frictional behaviour of employed pottery is not enough, then hole 17,47 wall 19,49 comprise the coating that is intended to reduce friction factor and therefore reduces the friction of pivot associated with it.As described below, above-mentioned coating can comprise the allotrope of carbon, for example amorphous carbon or Graphene.
In addition, preferably, at least one hole 17,47 comprises olive shape otch 53 and/or oil groove 21,51 in part of its height at least, and this olive shape otch 53 and/or oil groove 21,51 are intended to reduce the friction surface with described element pivot, is beneficial to simultaneously that it is lubricated.In fact, as shown in Figure 3 and Figure 4,17,47 cross section associated with it increases gradually from the hole for the oil groove 21 of conical shaped, 51 cross section.Therefore, obviously, the pivot of element abuts against less surface and rotates slidably, and this has reduced friction.Also obvious, oil groove 21,51 makes described pivot easily to be lubricated, and this has further reduced described friction.
As Fig. 2 and shown in Figure 4, bridge clamping plate 1 comprise three pedestals 3,5,7, and described pedestal is intended to abut against base plate 31 to be installed, and the plate 9 of described bridge clamping plate extends above these three pedestals.Preferably, three pedestals 3,5,7 and plate 9 are one.In the example shown in Fig. 2, as can be seen, plate 9 has roughly crescent-shaped.
As shown in figures 1 and 3, base plate 31 also can comprise means of abrasion 33,35, and described means of abrasion 33,35 is intended at least to admit wheel set in the part of the thickness of the plate 39 of base plate 31.
Therefore, though the green compact of bridge clamping plate 1 and/or base plate 31 have very little thickness, that is, about 0.4mm is because the use of pottery can obtain to have point-device size of very high mechanical resistance power.
Therefore, obviously, in the example shown in Fig. 1 to Fig. 4, can obtain green compact in the following way: the phase one usually by etching crescent-shaped or disc-like shape roughly, then in the part of subordinate phase by optionally removing thickness in order to be defined for pedestal 3,5,7 a thickness and be used for plate 9 on the one hand and on the other hand at the means of abrasion 33 of plate 39,35 littler thickness.
Advantageously, when forming green compact, can also in plate 9,39 top section, make groove, in order to improve the aesthetic effect of described movement.In fact, for example, also can be at accurately etching numbering, trade mark and/or decoration on the thickness of element all or part of.
Now in conjunction with Fig. 5 to make element for example the method 61 of bridge clamping plate 1 and/or base plate 31 make an explanation.Method 61 mainly comprises the step 67 of step 60, the step 63 that forms the hole that forms green compact, the step 65 that forms olive shape otch and/or oil groove and formation coating.
Second step 63 is used to form each stationary installation 2,4,6 hole 11,41 and/or each supporting base 8,10,36,38,40 hole 17,47.In the phase one 62, as explained above, get the blank of bridge clamping plate 1 and/or base plate 31, the blank of these bridge clamping plate 1 and/or base plate 31 is processed into desirable size in advance and may uses mechanical removal method or laser cutting method grinds.Then, in the stage 64, use and destroy radiation method for example picosecond laser (pico-laser) or any machinery removal rule such as drilling etch- hole 11,41 and/or 17,47.
In first embodiment, shown in the two-wire among Fig. 5, step 65 comprises the stage 66, in this stage 66, uses and destroys for example picosecond laser etching oil groove 21,51 of radiation method.
In a second embodiment, shown in the single line among Fig. 5, step 65 comprises the stage 68, in this stage 68, uses machinery to remove rule such as line reaming (wire enlarging) etching oil groove 21,51.
After step 65 or after step 63, as shown in the dotted line among Fig. 5, method 61 also can comprise step 67, and this step 67 is used in the hole 11,17,47 wall 19,49 and forms low-friction coefficient or ductile coatings.
Can comprise for execution having physics or chemical vapor deposition than the material of the better tribological property of pottery by first modification of the step 67 shown in the single line.Above-mentioned material can for example be the allotrope of carbon, for example amorphous carbon or Graphene.
In second modification of step 67, method 61 also can comprise the stage 74 of the ductile coating 15 that is used to form stationary installation 2,4,6 shoulder 13.At this moment, the stage 74 can comprise physics or chemical gaseous phase or the liquid deposition of ductile material.Above-mentioned material can for example be gold, copper, nickel, NiP alloy, TiW alloy or AuCr alloy.
Certainly, the utility model is not limited to illustrated example, but comprises various modification and the change that it will be apparent to those skilled in the art that.Especially, the stationary installation 2,4 of appearance, 6 is used screw connection, yet they are not limited to such device.Can utilize be pressed into, bonding or clamp device replace screw connection.
