A watch dial polishing device

Abstract

This utility model discloses a watch dial polishing device, including a support frame. A worktable is rotatably mounted on the top of the support frame, and a reducer and a stepper motor are fixedly mounted on the bottom of the support frame. In this device, the arrangement of the worktable, reducer, stepper motor, and mounting slot allows multiple watch dials to be processed simultaneously. The rotation enables the synchronous execution of processes such as loading, polishing, and unloading, avoiding the time wasted due to frequent downtime for parts replacement in single-station mode. This significantly improves the continuous operation capability and processing volume per unit time. In addition, the inclusion of a dust collector, dust box, first connecting pipe, dust hood, tee, and telescopic hose allows for the cleaning of metal shavings, dust, and other impurities generated during the polishing process, thereby reducing contamination of the watch dial surface and minimizing the impact of dust on the equipment and operators.

Description

Technical Field

[0001] This utility model relates to the technical field of watch processing equipment, specifically a watch dial polishing device. Background Technology

[0002] A watch consists of parts such as the movement, case, dial, cover, case back, and bracelet shaft. In the production and processing of watch dials, dial polishing is a key process to ensure the quality of the product's appearance.

[0003] Traditional watch dial polishing equipment often employs a single-station design, meaning it can only polish one dial at a time. After completion, the machine must be stopped to change the workpiece before the next processing can begin. This single-station mode results in frequent machine stops, loading, and unloading operations, leading to low equipment utilization, poor production continuity, and difficulty in meeting the efficiency requirements of mass production. In addition, many existing watch dial polishing equipment are inconvenient for cleaning metal shavings, dust, and other impurities generated during the polishing process. These not only adhere to the dial surface, affecting the polishing quality, but may also contaminate the equipment and endanger the health of operators.

[0004] To address this problem, the present invention provides a watch dial polishing device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-6 A watch dial polishing device includes a support frame 1, a worktable 2 rotatably mounted on the top of the support frame 1, a reducer 3 fixedly mounted on the bottom of the support frame 1, a stepper motor 4 fixedly mounted on the bottom of the support frame 1, the output end of the stepper motor 4 being fixedly connected to the input end of the reducer 3, the output end of the reducer 3 being fixedly connected to the worktable 2, and several sets of mounting slots 5 arranged in a circular array on the worktable 2. Each set of mounting slots 5 is provided with a silicone positioning pad 6 inside, a wireless pressure sensor 7 is fixedly mounted on the bottom of each set of mounting slots 5, and a placement slot 8 is provided on the top of each set of silicone positioning pads 6.

[0024] A support plate 9 is fixedly installed at the top rear edge of the support frame 1. A vertical groove 10 is opened at the front end of the support plate 9. A threaded rod 11 is vertically and rotatably installed inside the groove 10. A servo motor 12 is fixedly installed at the top of the support plate 9. The output end of the servo motor 12 is fixedly connected to the threaded rod 11. A placement plate 14 is slidably installed inside the groove 10. The placement plate 14 is threadedly connected to the threaded rod 11. A polishing machine 15 is fixedly installed at the bottom of the placement plate 14 and directly above the corresponding mounting groove 5. A stabilizing rod 13 is vertically fixedly installed inside the groove 10. The stabilizing rod 13 is slidably connected to the placement plate 14.

[0025] Rubber pads 26 are fixedly installed at the four corners of the bottom of the support frame 1, and a PLC control panel 27 is fixedly installed at the left edge of the top of the support frame 1.

[0026] For ease of control, the stepper motor 4, servo motor 12, polishing machine 15, dust extraction fan 17, and lighting 25 are all electrically connected to the PLC control panel 27 and to an external power supply. Additionally, the wireless pressure sensor 7 has an internal signal transceiver module connected to the PLC control panel 27 and is powered by a battery. The stepper motor 4 is a 57HS22, and the wireless pressure sensor 7 is a SIN-PM800. When using this device, the operator first places the dial to be processed into the slot 8 on the silicone positioning pad 6, then places the silicone positioning pad 6 into the mounting slot 5. Then, the stepper motor 4 is started, causing the worktable 2 to rotate. As the worktable 2 rotates, the operator can simultaneously polish the dial and place other dials to be processed into the mounting slots 5. This setup facilitates material loading. The simultaneous execution of processes such as polishing and unloading avoids the time wasted due to frequent downtime for parts replacement in single-station mode, significantly improving the continuous operation capability and processing volume per unit time. In addition, in this device, the operator can use the silicone positioning pad 6 with corresponding shaped placement grooves 8 according to the shape of the dial, making the device more practical and easy to operate. When the stepper motor 4 drives one group of dials to be processed to a position directly below the polishing machine 15, the operator can start the servo motor 12, which drives the placement plate 14 to rise and fall through the threaded rod 11 until it reaches the appropriate height, and then start the polishing machine 15 to polish the dial. During the polishing process, the pressure on the dial being polished can be observed intuitively and in a timely manner through the wireless pressure sensor 7, so that the height of the polishing machine 15 can be adjusted accordingly, which can to a certain extent avoid scratches or deformation of the dial due to excessive pressure.

[0027] Example 2:

[0028] Please see Figure 1-6 This embodiment provides a technical solution based on Embodiment 1: A fixing plate 16 is fixedly installed on the outer wall of the rear end of the support frame 1, a vacuum cleaner fan 17 is fixedly installed on the top of the fixing plate 16, a dust collection box 18 is also provided on the fixing plate 16, a first connecting pipe 19 is sealed to the output end of the vacuum cleaner fan 17, and the other end of the first connecting pipe 19 extends into the dust collection box 18. Vacuum hoods 20 are fixedly installed at an angle on both sides of the placement plate 14. A tee 21 is fixedly installed on the outer wall of the rear end of the support plate 9. A telescopic hose 22 is sealed to each set of vacuum hoods 20, and the other end of each set of telescopic hoses 22 is sealed to the tee 21. A second connecting pipe 23 is also sealed to the rear end of the tee 21, and the other end of the second connecting pipe 23 is sealed to the input end of the vacuum cleaner fan 17. A connecting plate 24 is fixedly installed on the outer wall of the front end of the placement plate 14, and a lighting lamp 25 is fixedly installed at the bottom of the connecting plate 24.

[0029] During the polishing process of the dial using this device, the operator can also activate the dust extraction fan 17 to suck up metal chips, dust and other impurities generated during the polishing process through the dust extraction hood 20. The dust is then transported to the dust collection box 18 through the telescopic hose 22, the second connecting pipe 23 and the first connecting pipe 19, which reduces the contamination of the dial surface by impurities to a certain extent, and also reduces the impact of dust on the equipment and operators.
