Figure 13 is two kinds of different geometries of fastening force for 15 μm and compliant member, the motion according to the pin on horizontal ordinate is shown and the curve map of the press-in/extrusion pressure of the bar clamping plate on the vertical scale changed.
Curve C 1 corresponds to e=0.05mm and L=0.50mm.Curve C 2 corresponds to e=0.10mm and L=0.50mm.In both cases, maximum extrusion pressure (negative part, negativepart) 1N is less than, this is gratifyingly (not think that the maximum extrusion pressure that should exceed is 3N for easily dismantling when not damaging parts for bar clamping plate, but for often by some less bar clamping plate of handling as escapement lever clamping plate, recommend the maximum, force being less than 1N).
Figure 14 is for the fastening force of the 15 μm geometric parameter different with two, motion according to pin is on the horizontal scale shown and the curve map of the press-in/extrusion pressure of bar clamping plate on the vertical scale that changes.Curve C 1 corresponds to e=0.10mm, and curve C 2 corresponds to e=0.05mm.Curve C 3 is minimum extrusion pressure.In this first embodiment, useful variable L is between 0.5mm to 0.7mm, and the thickness of band is between 0.05mm to 0.1mm.Utilize in this situation all geometric parameters used, the extrusion pressure of escapement lever clamping plate is satisfactory.
Figure 15 is three different cross sections for the spring in this second embodiment, motion according to pin is on the horizontal scale shown and the curve map of the press-in/extrusion pressure of bar clamping plate on the vertical scale that changes.Curve C 1 corresponds to the power for the spring of nominal section, and curve C 2 is for the minimum spring in cross section, and curve C 3 is for the maximum spring in cross section.In all three kinds of situations, maximum extrusion pressure (negative part, negativepart) is significantly less than 1N, and this is gratifying for easily dismantling when not damaging parts for bar clamping plate.This power is enough to be greater than the weight (about 0.1 gram force) of bar clamping plate and the product of safety coefficient (10) usually, and this safety coefficient gives the minimum confining force (this value depends on the quality of bar clamping plate) of about 0.01N for this example.
Figure 16 illustrates for 0.03mm
2to 0.05mm
2between the effective modification in cross section in, the curve map of the press-in/extrusion pressure of the bar clamping plate on the vertical scale changed according to the cross section being arranged on the spring on bar clamping plate in this second embodiment on the horizontal scale.Utilize all geometric parameters used in this case, the extrusion pressure of escapement lever clamping plate is gratifying (are greater than 0.01N and are less than 3N).
When the deflection curve of the drag spring of the embodiment of consideration Figure 12 (its particular condition for escapement lever clamping plate is made for the shape with optimization), consider martensite ag(e)ing steel spring if observed, then maximum stress keeps very low (1486MPa).Power between bar clamping plate and the second alignment pin being contained in the second cloudy alignment device is 0.3N, and the power be applied between the first pin and its device is 2.3N, is 2.3N by the direct acting power of external springs.Suppose coefficientoffrictionμ=0.15, then the confining force of this pin is 0.045N, and it is greater than the minimum confining force of recommendation.
The invention provides significant advantage.
Scheme proposed above make it possible to achieve bar clamping plate relative to motherboard can resetting, no matter and the manipulation performed at assembly process.
Current, wrist-watch wright needs repeatedly to dismantle and re-assembly escapement lever clamping plate, so that particularly in order to regulate the position of pallet stone.For conventional system, owing to cannot suitably reproduce this position from an assembly to another assembly all the time, so performed correction is not total energy produce the effect expected, this extends the process of the escapement of finishing movement further.For the present invention, the pivot position of escapement lever reproduces in the best way after dismantling/re-assembly operation.Thus, these alternative applications of the present invention in escapement lever clamping plate be best because the timing performance of movement is responsive especially to the position of escapement lever.
