Abstract
The utility model discloses a mechanism for fixing stud of a wrist watch. The stud fixing mechanism of the existing wrist watch has the disadvantages of a plurality of parts, complicated structure and uneasy disassembly and maintenance, which influences the isochronism of the watch. The utility model is characterized in that the stud arranged on the stud ring is provided with a flange with a conical surface and a boss, which can not only reduce the quantity of the parts and the total thickness of the watch, but also can make the parts easy to manufacture, disassembly and maintenance, decrease the cost and improve the quality. Consequently, the measuring accuracy of the watch is ensured.
Description
The utility model relates to the stud fixed mechanism of the hair-spring balance speed regulator of stem-winder.
In mechanical watch, be used for the stud fixed mechanism of escapement hairspring vibration speed regulator, three kinds of fixing modes were once arranged at present:
1, be to be packed in the axis hole of the stud pile protection of riveted on the outer anchor ear in the upper end of stud, and it is fixing with the stud axle nail of 0.4M, the structure that the lower end of stud links to each other with the hairspring outer end, this mode is not weighed complex structure, and part is many in addition, and the hairspring axial location is inaccurate, tangentially can't adjust, when the maintenance of folding dress, only force hairspring flexural deformation direction to adjust the off-centre and the take off angle of hairspring, so, cause stable reduction system's same period of hairspring material internal stress, and influence the tautochronism of wrist-watch, twist the screw of cutting 0.4M on the pile protection outside in addition, processed complex not only, and be difficult to ensure the quality of products.
2, be that though this mode has reduced part in addition, during the maintenance of folding dress, stud can't be pulled down from outer anchor ear with pack into by force fixed sturcture in the stud axis hole that has elastic opening of the stud that the upper end has a flange.
3, be on the basis of above-mentioned second kind of fixed form, the elastic opening size of stud axis hole increased to the stud diameter of axle connect size also, and have a stud of the garden conical surface in the middle part, force stud radially to enter in the stud axis hole along opening part, reinforce stud on outer anchor ear by the garden conical surface, though this mode can be dismantled stud arbitrarily when the maintenance of folding dress, but owing to be that radially folding is adorned, the easiliest cause hairspring flexural deformation, heavy then hairspring can not be worked, gently then influence tautochronism, condition adopts the flanged stud in upper end, has just increased the thickness of whole stem-winder.
The purpose of this utility model is to overcome and avoids above-mentioned shortcoming and defect part of the prior art, adopt the upper end to have the conical surface of falling the garden of chamfering, the middle part has the stud of boss and flange, realizes the fixed sturcture of the fastening stud axial location of elasticity and a kind of stud fixed mechanism of escapement speed regulator of stem-winder is provided.
The purpose of this utility model can realize by following structure: the stud fixed sturcture of the escapement hairspring speed regulator of stem-winder comprises having in plane of a loop one side and is processed with the conical surface hole, big garden that cooperates with the balance staff anti-rattler, link to each other with the stud axis hole fixed sturcture of stud of lower end and the adhesion of hairspring outer end of the outer anchor ear that opposite side is processed with the outer shaft hole that connects with stud and upper end.Technology special feature of the present utility model is that the side on the anchor ear plane outside is processed with the stud axis hole, other in the stud axis hole along axis hole horizontal axis and parallel with it the elasticity elongated opening that is symmetrical in this horizontal axis of offering with distending function, below the stud axis hole, can be enclosed in the stud of the solid of revolution that rotates in the stud axis hole, the upper end of solid of revolution stud is the conical surface of falling the garden that has chamfering, below it, be processed with outside the flange of the parallel close-fitting band boss of anchor ear lower plane, adjust the off-centre of hairspring and swing duty such as frame in order to make it safe ready ground, avoid the flexural deformation of hairspring and cause the error of system's tautochronism, technical characterictic of the present utility model also to be outside the lower surface of stud, to be provided with to make its direction corresponding with the boss direction on the flange and keep the opening of the tangential orientation unanimity after the hairspring adhesion.
Specific embodiments of the invention are described in further detail in conjunction with Fig. 1, Fig. 2:
Fig. 1 is a front view of the present utility model
Fig. 2 is a top view of the present utility model
From the graph, planar annular one side on the anchor ear 3 is processed with stud axis hole 1 outside, and in axis hole room 1 along the axis hole horizontal axis and parallel with it the flexible elongated opening 2 that is symmetrical in this horizontal axis of offering with distending function, when pack into below axis hole 1 in the upper end of stud 4, because the upper surface of stud 4 is chamfering and just can leads and enter in the axis hole 1, at this moment, because oblong openings 2 has the distending function, stud 4 can be entered smoothly, the elastic reaction that is subjected to simultaneously oblong openings 2 again forces the conical surface of falling the garden 8 of stud 4 to be fixed in the axis hole 1, the garden tapering of the inverted cone surface 8 of stud 4 is being between 1:8～1:2, but be preferably 1:3, the hole inner face of fixing back it and axis hole 1 forms an angular clearances naturally, so it is free to rotate, and make stud 4 become the single-revolution body, the continue bottom of stud 4 conical surfaces of falling the garden 8 is processed with the flange 6 of band boss 5, the last plane of flange 6 closely cooperates with the lower plane of outer anchor ear 3 is parallel, when the effect that is subjected to the stud 4 upper end conical surfaces of falling the garden 8, outer anchor ear 3 is pressed on the last plane of flange 6, make the secure fixation of stud 4 at axial location, simultaneously, since flange 6 outside anchor ear 3 below, not only make stud 4 by the gross thickness of adorning conveniently and reduce widely mechanical watch than prior art, and since flange 6 and hairspring be in together outer anchor ear 3 below, what hairspring was carried out when the maintenance of folding dress moves axially, can not cause hairspring flexural deformation, and the tautochronism that guarantees to keep in repair the back stem-winder, be provided with opening 7 in the lower surface of stud 4, and the outer end 9 of adhesion hairspring therein, because the direction of opening 7 is consistent corresponding with the direction of boss 5, stir boss 5, stud 4 is rotated in stud axis hole 1, nationality is adjusted the eccentric of hairspring with safe ready ground and is swung duty such as frame, and the tangential orientation of change hairspring, the isochronal error of stopping to cause the flexural deformation of hairspring when mechanism's table folding dress keeps in repair and influencing table, the assembly quality of raising stem-winder.
The utility model compared with prior art has the following advantages:
1, the number of packages amount is few in addition, reduces the gross thickness of stem-winder, is easy to processing and assembling, reduces cost.
2, folding fills easy to maintenancely, avoids hairspring flexural deformation, guarantees assembly quality, guarantees the measuring accuracy of stem-winder.
