Description

Technical Field

[0001] This invention relates to the field of equipment polishing technology, specifically to a high-precision polishing device for mechanical watch dials. Background Technology

[0002] Mechanical watches can generally be divided into two types: hand-wound and automatic. The power source of a mechanical watch is the mainspring inside the movement, which drives the gears and then the hands. Due to their fine craftsmanship, ease of use, and long service life, mechanical watches are very popular.

[0003] Over time, the dial of a mechanical watch inevitably suffers some wear and tear. Severe wear significantly affects the watch's appearance. Current technology for polishing and maintaining worn watch dials mostly involves manual polishing or using auxiliary equipment like electric drills. However, for high-precision polishing of mechanical watch dials, the relatively small diameter makes manual polishing time-consuming and laborious. Furthermore, the delicate internal components of a mechanical watch dial require precise control of the contact force between the polishing paper or cloth and the dial. Excessive contact force can damage internal components due to vibrations, while insufficient contact force hinders surface polishing. Therefore, we propose a high-precision polishing device for mechanical watch dials. Summary of the Invention

[0024] (III) Beneficial Effects

[0025] Compared with known public technologies, the present invention provides a high-precision polishing device for mechanical watch dials, which has the following beneficial effects:

[0026] 1. In this invention, when performing high-precision polishing and maintenance on a mechanical watch dial, the watch dial support component facilitates the stabilization of the watch dial's position. Subsequently, the detection and adjustment component facilitates the movement of the mechanical watch dial to the polishing cloth on the multi-grid repositioning component.

[0027] 2. In the polishing process of a mechanical watch dial, the watch dial bearing component enables the mechanical watch dial to reciprocate, greatly improving the polishing efficiency and effect. Simultaneously, the detection and adjustment component allows for the detection of the polishing pressure exerted by the polishing cloth on the watch dial surface. This effectively prevents damage to internal parts of the watch dial due to excessive pressure during polishing, while ensuring accurate contact between the polishing cloth and the watch dial for polishing, significantly improving polishing efficiency and precision.

[0028] Therefore, this high-precision polishing device for mechanical watch dials can not only replace manual labor in polishing most areas of the mechanical watch dial with high precision at different grits, but also detect the polishing pressure during the polishing process to prevent damage to the mechanical watch dial, making it highly versatile.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see Figures 1 to 7 A high-precision polishing device for mechanical watch dials, comprising:

[0042] Polishing power box 1 is equipped with a multi-eye polishing mechanism and a dial repositioning support mechanism. The dial repositioning support mechanism is located on one side of the multi-eye polishing mechanism. A support frame is installed at the bottom of the polishing power box 1 to facilitate the support of the device. In actual use, the support frame can be customized to different heights according to the installation height of the equipment to facilitate the use of the equipment. A door is provided on one side of the polishing power box 1 for the installation and maintenance of the equipment inside the polishing power box 1.

[0043] The multi-mesh polishing mechanism includes a polishing drive assembly 001 and a multi-mesh shifting assembly 002. The polishing drive assembly 001 is mounted on the polishing power box 1, and the multi-mesh shifting assembly 002 is mounted on the polishing drive assembly 001. The multi-mesh shifting assembly 002 is equipped with multiple polishing cloths 2 with different mesh numbers, which are used to perform high-precision polishing operations with multiple different mesh numbers on the surface of the mechanical dial 3.

[0044] The aforementioned polishing drive assembly 001 includes a drive motor 4, a small bevel gear 5, a large bevel gear 6, a drive rod 7, a rod protective sleeve 8, and a large bevel gear 9. The drive motor 4 is installed inside the polishing power box 1, and its output end is fixedly installed between the drive motor 4 and the small bevel gear 5. The drive rod 7 is rotatably mounted on the polishing power box 1 and partially extends above it. Both the large bevel gear 6 and the large bevel gear 9 are fixedly mounted on the drive rod 7, and the large bevel gear 6 meshes with the small bevel gear 5. The rod protective sleeve 8 is fixedly mounted on the polishing power box 1, and part of the drive rod 7 rotates... The drive rod is installed inside the protective sleeve 8. Specifically, by starting the drive motor 4, the output end of the drive motor 4 drives the small bevel gear 5 to rotate, the small bevel gear 5 drives the large bevel gear 6 to rotate, the large bevel gear 6 drives the drive rod 7 to rotate, and the drive rod 7 drives the large bevel gear 9 to rotate. By setting the protective sleeve 8, the drive rod 7 is prevented from being exposed and causing injury during rotation. At the same time, by applying lubricating oil between the drive rod 7 and the protective sleeve 8, the stability of the drive rod 7 during rotation and the service life of the drive rod 7 can be improved.

[0045] The aforementioned multi-eye transposition assembly 002 includes a transposition protection box 10, a transposition rotary drum 11, multiple polishing protective sleeves 12, multiple polishing rotating rods 13, multiple barbed polishing rotating heads 14, multiple small bevel gears 15, a transposition large gear 16, a transposition small gear 17, and a transposition motor 18. The transposition protection box 10 is fixedly mounted on the polishing power box 1. The transposition rotary drum 11 is rotatably mounted on the rotating rod protective sleeves 8, and a portion of the rotating rod protective sleeve 8 and the large bevel gears 9 are located inside the transposition rotary drum 11. The transposition rotary drum 11 is located inside the transposition protection box 10, and the multiple polishing protective sleeves 12 are at equal angles. Connected to the transposition drum 11, multiple polishing rotating rods 13 are rotatably mounted inside multiple polishing protective sleeves 12. Multiple small bevel gears 15 are fixedly mounted on one side of the multiple polishing rotating rods 13, and each of the multiple small bevel gears 15 meshes with a large bevel gear 9. Multiple barbed polishing heads 14 are detachably mounted on the other side of the multiple polishing rotating rods 13. Multiple polishing cloths 2 of different mesh sizes are wound around the multiple barbed polishing heads 14. The transposition motor 18 is mounted on the transposition protective box 10, and the output end of the transposition motor 18 extends to the transposition protective box 10. The internal components are fixedly installed with the small shifting gear 17, and the large shifting gear 16 is fixedly installed on the shifting cylinder 11. The large shifting gear 16 meshes with the small shifting gear 17. Specifically, when the large bevel gear 9 rotates, it drives multiple small bevel gears 15 to rotate. These small bevel gears 15 drive the polishing rod 13 connected to them to rotate, which in turn drives the barbed polishing head 14 to rotate. The polishing cloth 2 wrapped around the barbed polishing head 14 polishes the surface of the mechanical dial 3, achieving a higher grit finish on the mechanical dial 3. During polishing, the shifting motor 18 is started, and the output of the shifting motor 18 drives the shifting pinion 17 to rotate. The shifting pinion 17 drives the shifting gear 16 to rotate, and the shifting gear 16 drives the shifting drum 11 to rotate. The rotation of the shifting drum 11 drives the multiple polishing protective sleeves 12 and multiple polishing rotating rods 13 on it to rotate, so that multiple small bevel gears 15 revolve around the large bevel gear 9, thereby changing the position of the polishing cloth 2. In order to facilitate the precise changing of the position of the polishing cloth 2, the shifting motor 18 can be selected as a stepper motor.

[0046] It should be further explained that the cross-sectional area of ​​the barbed polishing head 14 is convex. After the polishing cloth 2 is wrapped around it, the polishing cloth 2 can make better contact with the mechanical dial 3. In actual use, the barbed polishing head 14 can be replaced according to the shape of the mechanical dial 3. When the polishing cloth 2 needs to be replaced, simply rotate one end of the polishing cloth 2 around the barbed polishing head 14 to quickly replace the polishing cloth 2. In actual use, in order to make the polishing cloth 2 polish the mechanical dial 3 better, after the polishing cloth 2 is set, polishing oil for auxiliary polishing can be applied to the polishing cloth 2. In this invention, lubricating oil can also be applied between the polishing protective sleeve 12 and the polishing rotating rod 13. The polishing protective sleeve 12 not only increases the stability of the polishing rotating rod 13 when rotating, but also effectively prevents the polishing rotating rod 13 from causing injury when rotating.

[0047] The dial repositioning support mechanism includes a detection and adjustment component 003 and two sets of dial support components 004. The detection and adjustment component 003 is mounted on the polishing power box 1 and is used to move the position of the mechanical dial 3 and to detect the polishing pressure of the multi-eye repositioning component 002 on the mechanical dial 3. Both sets of dial support components 004 are mounted on the detection and adjustment component 003 and are used to stably support the mechanical dial 3 at different positions and to drive the mechanical dial 3 to rotate.

[0048] The aforementioned detection and adjustment assembly 003 includes a lateral adjustment electric cylinder 19, a longitudinal adjustment electric cylinder 20, an adjustment slider 21, a high-precision pressure sensor 22, and a double-headed support bracket 23. The polishing power box 1 has an adjustment through hole. The adjustment slider 21 is slidably installed inside the adjustment through hole. The lateral adjustment electric cylinder 19 is installed on one side of the polishing power box 1, and its output end extends into the interior of the polishing power box 1 and is fixedly installed between it and the adjustment slider 21 via a connecting plate. The longitudinal adjustment electric cylinder 20 is installed on the adjustment slider 21 and located inside the polishing power box 1. The output end of the longitudinal adjustment electric cylinder 20 passes through the adjustment slider 21 and extends above the polishing power box 1, and is fixedly installed between it and the high-precision pressure sensor 22. The detection end of the high-precision pressure sensor 22 is fixedly installed between it and the double-headed support bracket 23. Both sets of dial support assemblies 004 are installed on the double-headed support bracket. On the frame 23, specifically when the position of the mechanical dial 3 on the dial support assembly 004 is moved by the detection and adjustment component 003, the horizontal adjustment electric cylinder 19 is activated. The output end of the horizontal adjustment electric cylinder 19 drives the adjustment slider 21 to move horizontally. The vertical adjustment electric cylinder 20 is activated. The output end of the vertical adjustment electric cylinder 20 drives the high-precision pressure sensor 22 and the double-head support bracket 23 to move, thereby adjusting the position of the mechanical dial 3 so that the upper surface of the mechanical dial 3 comes into contact with the designated polishing cloth 2. The polishing pressure between the polishing cloth 2 and the mechanical dial 3 can be detected by the high-precision pressure sensor 22. When the polishing pressure is within the specified pressure range, the normal contact between the polishing cloth 2 and the mechanical dial 3 can be guaranteed, and the internal parts of the mechanical dial 3 will not be damaged due to excessive polishing pressure. The polishing operation of the mechanical dial 3 can be achieved quickly.

[0049] like Figure 1 and Figure 4As shown above, one of the dial support components 004 includes an electric suction cup 24, a support drive box 25, a support rotating rod 26, a rotary electric cylinder 27, an adjusting gear plate 28, and an adjusting gear 29. The support drive box 25 is fixedly mounted on the double-headed support bracket 23. Part of the support rotating rod 26 is rotatably mounted inside the support drive box 25. The electric suction cup 24 is mounted on the support rotating rod 26 and is used to adsorb the mechanical dial 3. The rotary electric cylinder 27 is mounted on one side of the support drive box 25 and is used for rotary adjustment. The output end of the rotating cylinder 27 extends into the interior of the bearing drive box 25 and is fixedly installed between it and the adjusting gear plate 28. The adjusting gear 29 is fixedly installed on the bearing rotating rod 26. The adjusting gear plate 28 meshes with the adjusting gear 29. Specifically, by activating the electric suction cup 24, the glass viewing surface of the mechanical dial 3 can be adsorbed. This adsorption surface generally does not require polishing. After stabilizing the position of the mechanical dial 3 by the electric suction cup 24, when polishing the mechanical dial 3 with the polishing cloth 2, the rotating electric cylinder 27 is activated to rotate... The output of the electric cylinder 27 drives the adjusting gear plate 28 to reciprocate. The adjusting gear plate 28 drives the adjusting gear 29 to reciprocate. The rotation of the adjusting gear 29 drives the bearing rod 26 to rotate. The bearing rod 26 drives the mechanical dial 3 on the electric small suction cup 24 to reciprocate. To facilitate better polishing of the mechanical dial 3, the maximum rotation angle of the mechanical dial 3 is set to 360° for optimal performance. This invention uses two sets of dial bearing components 004, one of which is used for polishing the back of the mechanical dial 3. One set of equipment is used to polish the surface, while another set is used to polish the sides of the mechanical dial 3. In the actual polishing operation of the sides of the mechanical dial 3, since the sides of the mechanical dial 3 are connected to the watch strap, the sides of the mechanical dial 3 are mostly irregular in shape. In the actual polishing process, the equipment can polish the areas that are not connected to the watch strap, thus achieving polishing of a large area of ​​the mechanical dial 3. The remaining small areas on the mechanical dial 3 near the watch strap can be manually polished to achieve a complete polishing operation of the mechanical dial 3.

[0050] Example 2

[0051] Embodiment 2 of the present invention further supplements Embodiment 1 by the following:

[0052] like Figure 4 As shown, the present invention also includes a dial positioning component 005 installed on one of the dial support components 004. The dial positioning component 005 is used to accurately position the mechanical dial 3 when it is placed on the dial support component 004.

[0053] Furthermore, in a preferred embodiment of the present invention, the dial positioning assembly 005 includes a positioning frame 30, a bidirectional screw 31, a positioning turntable 32, a limiting slide bar 33, two nuts 34, two positioning sliders 35, and two positioning markers 36. The positioning frame 30 is fixedly mounted on one of the load-bearing drive boxes 25. The bidirectional screw 31 is rotatably mounted on the positioning frame 30. The positioning turntable 32 is fixedly mounted on one end of the bidirectional screw 31. The limiting slide bar 33 is fixedly mounted on the positioning frame 30. Both nuts 34 are threadedly connected to the bidirectional screw 31. The two positioning sliders 35 are respectively fixedly mounted on the two nuts 34, and both positioning sliders 35 are slidably mounted between themselves and the limiting slide bar 33. The two positioning markers 36 are respectively fixedly mounted on the two positioning sliders 35. Each of the two positioning rods 36 has at least two positioning posts 37 corresponding to the center point of the electric suction cup 24. Specifically, when the mechanical dial 3 is attached to the designated electric suction cup 24, the positioning turntable 32 is rotated, which drives the bidirectional screw 31 to rotate. The rotation of the bidirectional screw 31 causes the two nuts 34 on it to move relative to each other. The movement of the two nuts 34 drives the two positioning sliders 35 to move. The positioning sliders 35 drive the positioning rods 36 to move, thus defining the position of the mechanical dial 3. At the same time, the center position of the mechanical dial 3 is aligned with the corresponding positioning post 37, so that the center point of the mechanical dial 3 coincides with the center point of the electric suction cup 24, thereby achieving precise positioning of the mechanical dial 3.

[0054] To facilitate heat dissipation of the equipment inside the polishing power box 1, a cooling fan 38 is installed on one side of the polishing power box 1, and multiple heat dissipation holes are opened on the other side of the polishing power box 1. By starting the cooling fan 38, the high-temperature gas inside the polishing power box 1 can be discharged from the polishing power box 1, thereby achieving the heat dissipation function.

[0055] In order to facilitate the protection of the transposition gear 16 and the transposition pinion 17, a gearbox 39 for protecting the transposition gear 16 and the transposition pinion 17 is installed on the transposition protection box 10.
