Description

Technical Field

[0001] This utility model relates to the field of watch manufacturing, and more specifically to the field of mechanical watch manufacturing.

[0002] More specifically, this utility model relates to an assembly of two watch parts for a watch movement. Background Technology

[0003] In most mechanical watches, the various components are assembled together on the plate by known conventional means such as press-fitting, threaded connection, fitting, or less commonly, bonding or welding.

[0004] These components are typically mounted within the movement and stacked in a series of planes that are substantially parallel to the mainplate. Examples of these components include gears and plates.

[0005] Some components must be mounted perpendicular to the plane of the machine plate, especially, for example, the rotating spindle and balance shaft used for gears or balance wheels. Due to their small size, the rotating spindle and balance shaft are easy to assemble.

[0006] However, the assembly of some larger components within the movement is more complex, especially when they must be assembled orthogonally to the mainplate.

[0007] Furthermore, they may need to interact with other parts of the movement, for example, through interlocking or meshing, which makes them difficult to assemble.

[0008] Another issue related to the assembly of watch components is that there may be clearance between two components after assembly. Utility Model Content

[0009] The purpose of this invention is to overcome some or all of the above-mentioned disadvantages by providing an assembly device for assembling watch components into a watch movement, which avoids the aforementioned problems.

[0010] Therefore, the present invention relates to an assembly of two watch components for a watch movement, comprising a first watch component and a second watch component, the first watch component being, for example, a plate extending in a first plane, and the second watch component being, for example, an actuator of an actuation system, the assembly comprising an assembly means for assembling the first watch component to the second watch component.

[0011] The present invention is characterized in that the assembly device includes a positioning component and a bearing means. The positioning component is used to position the second watch component on the first watch component in a plane substantially parallel to the first watch component. The bearing means is used to press against the second watch component so as to lock the second watch component on the first watch component in a direction substantially orthogonal to the first watch component.

[0012] Thanks to this invention, the assembly of two clock components can be achieved efficiently and simply, because the second clock component is positioned on the first clock component and held laterally by the positioning component, and then the pressing component is arranged on the second clock component to lock the second clock component in place and assemble it on the first clock component.

[0013] These assembly devices are simple and effective because the positioning component places the second watch component in a plane substantially parallel to the plane of the first watch component, and the pressing component holds the second watch component in a second direction perpendicular to the aforementioned plane.

[0014] Furthermore, this component makes it easy to assemble watch parts perpendicular to the circuit board.

[0015] In one particular embodiment of the present invention, the second clock component extends in a plane substantially perpendicular to the first clock component.

[0016] According to a specific embodiment of the present invention, the positioning component includes at least one catch, preferably two catches, disposed on the second watch component, and at least one hole, preferably two holes, disposed in the first watch component, such that each catch is inserted into one hole to assemble the two watch components.

[0017] According to a specific embodiment of the present invention, at least one claw can engage with the hole.

[0018] According to a specific embodiment of the present invention, the pressing component includes an assembly body disposed on a first watch component, and the second watch component includes a pressing surface, on which the assembly body presses against to lock the second watch component in place.

[0019] According to a specific embodiment of the present invention, the assembly body includes a rigid tab for pressing against the second watch component.

[0020] According to a specific embodiment of the present invention, the second watch component has an opening through which a rigid tab can pass.

[0021] According to a specific embodiment of the present invention, the assembly device includes a screw, and the assembly body includes a passage for assembling the assembly body to a first watch component, the first watch component being provided with an internal threaded hole for the screw.

[0022] According to a specific embodiment of the present invention, the second clock component includes a stationary portion intended to be mounted on the first clock component, and a movable portion capable of moving relative to the first clock component.

[0023] According to a specific embodiment of the present invention, the stationary portion includes one or more of the aforementioned claws.

[0024] According to a specific embodiment of the present invention, the opening is arranged between the stationary portion and the movable portion.

[0025] According to a specific embodiment of the present invention, the assembly body is pressed against the stationary part.

[0026] This utility model also relates to a watch movement that includes such a watch component.

[0027] This utility model also relates to a timepiece, such as a wristwatch, that includes such a timepiece movement. Attached Figure Description

[0034] In the following description, the subject of this invention is a watch assembly comprising an assembly device for assembling two watch parts, wherein the first watch part is the mainplate of a watch movement, and the second watch part is an actuator for a device for adjusting a regulating mechanism. However, such an assembly may involve other parts of a watch movement and is by no means limited to these parts or other parts of the regulating mechanism.

[0035] Figure 1An embodiment of a watch movement is illustrated schematically, including a plate with recesses and a regulating mechanism 1. Such a movement is, for example, arranged in a watch (e.g., a wristwatch).

[0036] The regulating mechanism 1 includes an inertial mass, in this example, a ring balance wheel 23, a hairspring 25 configured to oscillate the inertial mass as an elastic restoring element of the inertial mass, a balance shaft, and a balance bridge (not shown in the figure). These components are stacked from bottom to top in the following order: first clock component 22, balance wheel 23, and hairspring 25.

[0037] The balance shaft passes through the center of the balance wheel and hairspring 25. The balance shaft is held by two anti-vibration bearings 28, located at both ends of the balance shaft. The first bearing is located below the balance clamp in the mechanism plate 22, and the second bearing 28 is located in the balance clamp. The balance clamp has a through-hole in which the second bearing 28 is held.

[0038] like Figure 2 As shown, the hairspring 25 preferably extends substantially within a single plane. The hairspring 25 includes a flexible strip 2 wound around itself multiple times, the strip 2 having a predetermined stiffness. The inner end 9 of the strip 2 is integrally formed with or assembled with a rigid support 3, the rigid support 3 being commonly referred to as the inner stud. The rigid support 3 is generally triangular in shape and is passed through by the balance shaft.

[0039] The hairspring 25 also includes an adjustment device for adjusting its stiffness. For example, when the regulating mechanism is installed in a watch movement, this adjustment device is particularly actuated by the user.

[0040] The adjustment device includes a flexible element 5, which is arranged in series with the strip 2, i.e., following the strip, preferably as an extension thereof. The flexible element 5 connects the outer end 4 of the strip 2 to the rigid support 53. The flexible element 5 and the outer end 4 of the strip 2 are integral. The flexible element 5 is a component distinct from the strip 2.

[0041] The flexible element 5 adds additional stiffness to the strip 2. The flexible element 5 is preferably stiffer than the strip 2. In this example, the flexible element 5 is arranged as an extension of the strip 2. Preferably, the adjusting device is integral with the strip 2, or even made of the same material (e.g., silicon).

[0042] In this embodiment of the hairspring, the flexible element 5 includes two flexible portions 15 and 16, each of which connects the strip 2 to the fixed support 53.

[0043] The two flexible portions 15 and 16 are arranged relative to each other in a manner symmetrical about axis A of the hairspring 25. In other words, the two flexible portions 15 and 16 are positioned symmetrically about said axis A.

[0044] On the one hand, axis A passes through the center O of the hairspring; on the other hand, axis A preferably passes through the outer end 4 of strip 2.

[0045] Therefore, the two flexible parts 15 and 16 are arranged on the outer periphery of the hairspring, such that the two flexible parts 15 and 16 are arranged at the same distance from the center O of the hairspring 25.

[0046] The two flexible portions 15 and 16 are preferably arranged in a "mirror image" position relative to each other about axis A. For this purpose, the two flexible portions 15 and 16 are preferably substantially identical.

[0047] Both flexible portions 15 and 16 include curved flexible blades 55, which are preferably semi-circular and extend from the end of the fixed support 53. Each curved flexible blade 55 is also connected to the outer end 4 of the strip 2 via a flexible blade 7.

[0048] The fixed support 53 is trapezoidal and is enclosed by flexible blades 7.

[0049] The adjusting device for adjusting the hairspring 25 also includes a prestressing device 6 for applying a variable force or torque to the flexible element 5. This allows for adjustment of the hairspring's stiffness. Thanks to the prestressing device 6, the torque or force can be continuously adjusted. In other words, the torque or force is not limited to a single point value. Therefore, the stiffness of the flexible element 5 can be adjusted very precisely.

[0050] Preferably, the prestressing device 6 applies substantially the same force or torque to each flexible part 15, 16. The direction of the force is preferably substantially symmetrical.

[0051] The prestressing device 6 also includes two rods 14 and 26, each of which connects the bending blade 55 to the same movable body 19, which is arranged on the other side of the hairspring 25 relative to the fixed support 53.

[0052] The movable body 19 is, for example, U-shaped, thereby allowing it to engage with an actuator, which is provided, for example, with a hook or finger that inserts into the U-shape, since the U-shape is arranged tangentially to the rods 14, 26.

[0053] A variable force or torque is applied to the movable body 19. The variable force or torque is transmitted at least partially to the bending blades 55 of the flexible portions 15 and 16 of the flexible element 5 via the rods 14 and 26.

[0054] In order to apply variable force or torque to the hairspring 25, the speed regulating mechanism includes a specific actuation system 20.

[0055] In this embodiment, the speed regulating mechanism 1 includes an outer pile retainer 31 with a suspended outer pile 34. The outer pile retainer 31 is mechanically connected to the flexible element 5 but does not obstruct the strip 2. The outer pile retainer 31 surrounds the second bearing 28. For this purpose, the outer pile retainer 31 includes a central ring arranged around the second bearing 28, which rests on a swing plate (not shown).

[0056] The outer pile 34 cooperates with the rigid support member 55. In this way, the prestressing device 6 and the flexible element 5 are supported by the outer pile retainer 31 on which they are suspended.

[0057] Furthermore, the outer pile 34 is rigidly attached to the rigid support 55. In other words, the outer pile 34 and the rigid support 55 are integral. The outer pile 34 and the hairspring 25 are assembled, for example, by adhesive bonding, brazing, fusion welding, metal-glass deformation, or mechanical fastening.

[0058] The outer stud 34 is movable relative to the first watch component 22. For this purpose, the outer stud retainer 31 is rotatable relative to the first watch component 22 about the second bearing 28. The outer stud retainer 31 can, for example, be displaced within an angular range of 20° or even 10°.

[0059] By shifting the outer peg 34 relative to the first clock component 22, the yaw rate of the speed regulating mechanism 1 can be adjusted.

[0060] The actuation system 20 also includes a second clock component 30, which is an actuator configured to actuate the movable body 19. The second clock component 30 is mechanically connected to the prestressing device 6 and is configured to perform at least partially a substantially linear, preferably linear, displacement in a plane substantially perpendicular to the machine plate in order to actuate the prestressing device 6.

[0061] In other words, at least a portion of the second watch component 30 moves substantially in a straight line, unlike the outer stud retainer 31, which rotates about an axis in a plane substantially parallel to the movement plate. Thus, at least a portion of the second watch component 30 moves toward or away from the hairspring 25 in a direction substantially oriented toward the hairspring.

[0062] Preferably, the displacement direction of the second clock component 30 is substantially radial relative to the balance wheel 23 and the hairspring 25. This ensures that the second clock component 30 points towards the center of the balance wheel 23 and the hairspring 25 along the line of its movement. This also makes the timekeeping error setting independent of the yaw setting. More specifically, the yaw of the regulating mechanism 1 can be adjusted by shifting the outer stud 34 relative to the first clock component 22.

[0063] The second clock component 30 is eccentric relative to the speed regulating mechanism; that is, the second clock component 30 is mounted at a certain distance from the center of the speed regulating mechanism 1 and is only connected to the movable body 19 of the regulating device. Therefore, the second clock component 30 is not directly mounted on the speed regulating mechanism 1, for example, like the outer stud retainer on the bearing 28 of the speed regulating mechanism 1.

[0064] Therefore, the watch movement includes component 10, which includes a first watch part 22 and a second watch part 30. In this example, the first watch part 22 is a plate and the second watch part 30 is an actuator of the regulating device.

[0065] In this embodiment, the first watch component 22 is the mainplate of the watch movement, and the second watch component 30 is the actuator. The second watch component 30 is mounted on the first watch component 22. The second watch component 30 is mounted perpendicular to the first watch component 22.

[0066] exist Figure 3 In this design, the second watch component 30 specifically includes a stationary portion 33, a movable portion 37, and a spring portion 35. The stationary portion 33 is mounted on the first watch component 22. The movable portion 37 is movable relative to the first watch component 22 and connected to the rods 14 and 26. The spring portion 35 is formed by a flexible bearing that connects the movable portion 37 to the stationary portion 33. The stationary portion 33 and the movable portion 37 are preferably rigid. The stationary portion 33, the spring portion 35, and the movable portion 37 are preferably arranged in the same plane. Therefore, the second watch component 30 is generally flat and extends substantially in a single plane.

[0067] In order to actuate the movable body 19, the second clock component 30 includes a hook 39 that engages with the movable body 19 in a U-shape. The hook 39 is closed, but it may also be partially open.

[0068] By radially displacing the movable portion 37 of the second clock component 30 relative to the hairspring 25, the movable body 19 can be pulled or pushed radially relative to the hairspring 25, thereby actuating the levers 14 and 26. This changes the stiffness of the flexible element 5, because the displacement of the levers 14 and 26 rigidly connected to the movable body 19 applies a force or torque of varying magnitude to the flexible element 5, causing a change in the stiffness of the flexible element 5, and thus a change in the stiffness of the entire hairspring 25. Therefore, the actuation system 20 enables adjustment of the timekeeping difference of the speed regulating mechanism 1.

[0069] The stationary portion 33 has a generally elongated shape and includes a bar 63 intended to be mounted on the first clock component 22.

[0070] As shown in the figure, the second clock component 30 is mounted on the first clock component 22, and is thus substantially perpendicular to the first clock component 22.

[0071] The spring portion 35 is positioned above the stationary portion 33, thereby extending above the horizontal position of the first clock component 22.

[0072] In this example, the spring section 35 includes two translation stages / steps 51, 52 with flexible blades, one arranged in series after the other. They are defined as being in series because the displacement of each translation stage is at least partially accumulated.

[0073] Each translation stage 51, 52 includes a pair of substantially parallel flexible blades 61, 62, and rigid sections 56, 57 on which the pair of flexible blades 61, 62 are mounted.

[0074] The first translation stage 51 is arranged on the stationary portion 33 and includes a first rigid section 56 that is elongated to be associated with a second translation stage 52, which is arranged end-to-end with the first translation stage 51 (i.e., arranged in opposite directions). Thus, the second pair of flexible blades 62 are substantially parallel to the first pair of flexible blades 61.

[0075] The second rigid section 57 is basically parallel to the first rigid section 56, but offset relative to the first rigid section 56.

[0076] This arrangement of translation stages 51 and 52 allows the movable part 37 to be moved in a substantially linear, preferably straight, manner, while maintaining the compactness of the second clock component 30.

[0077] By arranging the two translation stages end-to-end, the vertical deviations of the hooks 39 produced by each stage can compensate for each other. In this way, the hooks 39 will remain at approximately the same height during movement.

[0078] The movable portion 37 extends from the second section 57. The movable portion 37 is preferably rigid. In this example, the movable portion 37 has an elbow shape, which is formed by a first section 66 arranged perpendicular to the second section 57 and a second section 67 forming a right angle with the first section 66.

[0079] The hook 39 of the second watch component 30 is located at the branch end of the second section 67. At the free end of the first section 66, the protrusion 68 serves as a support for moving the movable part 37.

[0080] By pressing the protrusion 68 with more or less force, the movable part 37 moves substantially parallel to the stationary part 33, thanks to the deformation of the translation stages 51 and 52 of the spring part 35.

[0081] In this way, the hook 39 pulls the rods 14 and 26 with more or less force via the movable body 19, so as to actuate the adjustment device for adjusting the stiffness of the flexible element 5.

[0082] The displacement directions of the movable part 37 and the movable body 19 of the second clock component 30 are substantially orthogonal to the direction of the movable body 19, or orthogonal to the axis O.

[0083] Furthermore, the movable body 19 is preferably movable within the hook portion 39, such that when the movable body 19 undergoes angular displacement within the plane of the hairspring 25, the movable body 19 can slide.

[0084] For example, in order to adjust the yaw rate of the speed regulating mechanism 1, the outer stud retainer 31 must be able to rotate. Therefore, the hairspring 25 rotates with the outer stud retainer 31, and the movable body 19 slides in the hook portion 39.

[0085] Thanks to this actuation system 20, the oscillation can be adjusted without changing the position of the second watch component 30, especially its position relative to the movement plate. The mechanical connection between the second watch component 30 and the movable body 19 is maintained regardless of the position of the movable body 19 relative to the second watch component 30.

[0086] Therefore, this actuation system 20 enables the adjustment of timekeeping difference and yaw independently of each other, while maintaining a constant predetermined position of the second watch component in the movement, for example, relative to the mainplate and relative to the balance bridge 22.

[0087] The actuation system 20 also includes an adjustment component that cooperates with the second clock component 30 to enable the movable portion 37 of the second clock component 30 to be displaced.

[0088] like Figure 1 As shown, the adjusting component includes a pivoting adjusting lever 45, which is arranged to displace the movable portion 37 of the second watch component 30. The adjusting lever 45 is preferably arranged in a plane substantially perpendicular to the plane of the second watch component 30 and contacts the protrusion 68 of the movable portion 37.

[0089] The adjusting lever 45 has a pivot arm 69 and a support arm 71 connected to the hub 72 of the pivot adjusting lever 45.

[0090] The support arm 71 engages with the movable portion 37 of the second watch component 30 to mechanically displace the movable portion 37 through contact. The support arm 71 pushes the protrusion 68 of the movable portion 37 to a greater or lesser extent to move it. The hook 39 thus pulls the movable body 19, thereby pulling the rods 14, 26 of the hairspring 25 to a greater or lesser extent. The adjusting rod 45 is configured to pivot in a plane substantially perpendicular to the plane of the second watch component 30.

[0091] The adjusting rod 45 is configured to be mounted on the movement plate via a hub 72, which is rotatable around a tube 73 integrally formed with the movement plate.

[0092] Therefore, by rotating the adjusting rod 45 around the tube 73, the movable part 37 moves toward or away from the stationary part 33 in a plane parallel to the plate plane by means of the greater or lesser deformation of the spring part 35 of the second clock component 30.

[0093] The adjusting component also includes a control screw 70 mechanically connected to the pivot arm 69 to control the pivoting of the adjusting rod 45. The axis of the control screw 70 is arranged in the plane of the adjusting rod 45 along the direction of the pivot arm 69.

[0094] The control screw can be operated using a tool (such as a screwdriver 24), the tip of which is... Figure 1 As shown in the image.

[0095] Therefore, by tightening or loosening the control screw 70, the adjusting rod 45 and the second clock component 30 are actuated to move the hook 39, thereby moving the movable body 19 of the prestressing device 6.

[0096] The restoring force of the spring portion 35 of the second watch component 30 pushes the adjusting rod 45 against the control screw 70. In this way, the pivot arm 69 of the adjusting rod 45 remains against the control screw 70.

[0097] In the figure, the control screw 70, the adjusting rod 45, the movable part 37 of the second clock component 30, and the rods 14 and 26 are all in the first position, with the hook 39 slightly pulling on the movable body 19.

[0098] In the second position (not shown in the figure), the control screw 70 pushes the pivot arm 69 of the adjusting rod 45, causing the support arm 71, which contacts the protrusion 68, to push the movable part 37 of the second watch component 30 towards the stationary part 33 through the deformation of the spring part 35. This causes the hook 39 to pull the movable body 19, thereby pulling the rods 14 and 26, causing them to undergo centrifugal displacement. When the spring part 35 is in the deformable configuration, the flexible blades of the two translation stages 51 and 52 deform in opposite directions.

[0099] As shown in the figure, the second clock component 30 is mounted on the first clock component 22 in a manner substantially perpendicular to the first clock component 22.

[0100] Component 10 also includes an assembly device 40 for assembling the second watch component 30 (an actuator in this example) onto the first watch component 22 (a circuit board in this example).

[0101] According to the present invention, the assembly device 40 includes a positioning member 50 for positioning the second watch component 30 on the first watch component 22 in a plane substantially parallel to the plane of the first watch component 22. Therefore, the positioning member 50 prevents the second watch component 30 from moving on the first watch component 22 in a plane substantially parallel to the plane of the first watch component 22.

[0102] In this embodiment, the positioning component 50 includes at least one claw 41, preferably two claws 41 and 42, disposed on the second watch component 30, and at least one hole 43, preferably two holes 43 and 44, disposed in the first watch component 22, such that each claw 41 and 42 is inserted into one hole 43 and 44 to position the second watch component 30 on the first watch component 22.

[0103] In this example, two claws 41, 42 are arranged at opposite ends of the actuator. Specifically, they are arranged at the end of the stationary portion 33 of the second clock component 30, which is intended to be mounted on the first clock component 22.

[0104] Preferably, at least one claw 41 is engageable into the hole 43. The claw 41 is, for example, deformable so that it can be inserted into the hole 43. The claw 41 has a protrusion at its end that locks into the hole 43.

[0105] The chucks 41 and 42 and the holes 43 and 44 are arranged perpendicular to the plane of the machine plate.

[0106] The assembly device 40 also includes a pressing member 60 for pressing against the second watch component 30 so as to lock the second watch component 30 onto the first watch component 22 in a direction substantially orthogonal to the plane of the first watch component 22.

[0107] In this way, the second clock component 30 is held on the first clock component 22 to prevent it from moving off the movement plate. The second clock component 30 is thus assembled onto the first clock component 22 and rigidly connected to it.

[0108] The pressing member 60 includes an assembly body 46 mounted on the first watch component 22. The assembly member 40 includes a screw 47, and the assembly body 46 includes a passage 48 for assembling the assembly body 46 into the first watch component 22. The screw 47 is inserted through the passage 48 to thread the assembly body 46 into a hole 18 in the first watch component 22.

[0109] The assembly body 46 includes a peripheral recess 27 that engages with a protrusion 29 extending from the first watch component 22 to prevent the assembly body 46 from rotating around the screw 47.

[0110] The assembly body 46 includes a rigid tab 49 that extends to the second clock component 30 to press against the second clock component 30.

[0111] For this purpose, the second watch component 30 includes a pressing surface 64 on which a rigid tab 49 rests to apply force in order to hold the second watch component 30 on the first watch component 22.

[0112] The second clock component 30 includes an opening 58 to allow the rigid tab 49 to pass through the second clock component 30 at least partially.

[0113] Furthermore, the opening 58 preferably includes a vertical wall against which the rigid tab 49 is held to prevent the rigid tab 49 from rotating with the assembly body 46.

[0114] In this embodiment, the opening 58 is arranged to pass through the elastic portion 35 of the second clock component 30. More specifically, the opening 58 is arranged between the flexible blades 61 of the first translation stage 51, such that the rigid tab 49 presses against the bar 63 of the stationary portion 33. For example, the vertical wall is arranged at the base of the flexible blades 61 of the first translation stage 51.

[0115] It goes without saying that this utility model is not limited to the embodiments of the speed regulating mechanism described with reference to the accompanying drawings, and alternative solutions may be considered without departing from the scope of this utility model.
