Description

Technical Field

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

[0002] Currently, in the watch case processing industry, most watch case polishing fixtures on the market have obvious limitations in polishing the inner bevel of the lugs and cannot well meet the polishing requirements of the inner bevel. Therefore, in actual production, many companies still rely heavily on manual polishing by their staff. However, manual polishing requires operators to polish the inner bevel of each lug one by one, which is a tedious and time-consuming process. In large-scale production, this inefficient polishing method seriously restricts the production progress and increases production costs. At the same time, long-term manual operation can easily cause worker fatigue, further reducing work efficiency and polishing quality. Utility Model Content

Detailed Implementation

[0015] 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.

[0016] like Figures 1-5 As shown, this utility model provides a watch case polishing fixture, including a boss 4. The boss 4 is provided with a limiting component. The limiting component is configured to hold the watch case 9 on the boss 4 to prevent the watch case 9 from shifting during the polishing process, ensuring accurate polishing position and improving the polishing precision of the inner bevel 10 of the lug 3. In this embodiment, the limiting component includes a positioning protrusion 8 and at least two limiting protrusions 1, wherein the limiting protrusions 1 and the positioning protrusions 8 are spaced apart to form a slot that adapts to the contour of the watch case 9. The watch case 9 can be fitted onto the positioning protrusions 8. One of the limiting protrusions 1 abuts between two adjacent lugs 3, and the other limiting protrusion 1 abuts against the outer wall of the watch case 9 to restrict the watch case 9 from rotating relative to the protrusions.

[0017] The boss 4 has an inclined surface 2 on one side, so that the limiting component is inclined relative to the horizontal plane. The inclined design makes the inner inclined surface 10 of the lug 3 at a more suitable angle during polishing, which makes it easier to polish the inner inclined surface 10 of the lug 3, reduces the difficulty of operation, and improves the polishing efficiency. The limiting protrusion 1 has an arc surface 7 at one end facing the positioning protrusion 8, so that the limiting protrusion 1 can fit against the outer wall of the watch case 9, ensuring that the watch case 9 will not shake during the polishing process, thereby ensuring the polishing quality.

[0018] It also includes a base 5, a movable seat 6, and a telescopic assembly mounted on the base 5. The output end of the telescopic assembly is connected to the movable seat 6. The movable seat 6 moves up and down relative to the base 5 under the drive of the telescopic assembly. The boss 4 moves up and down together with the movable seat 6. The telescopic assembly includes a connecting rod 15 and an elastic return element 16 sleeved on its rod wall. The elastic return element 16 is a spring. The base 5 has a through hole 14, the movable seat 6 has a through hole 11 adapted to the connecting rod 15, and the boss 4 has a mounting hole 17 adapted to the connecting rod 15. The through hole 11... The diameter of the hole is smaller than that of the through hole 14. The connecting rod 15 passes through the through hole 14, the through hole 11 and the mounting hole 17 in sequence. The elastic reset element 16 is located inside the through hole 14, and one end of the elastic reset element 16 abuts against the end of the connecting rod 15, and the other end abuts against the bottom of the movable seat 6. During the polishing operation, when the polishing tool comes into contact with the watch case 9, a certain impact force will inevitably be generated. The spring can absorb and disperse this impact force through its own elastic deformation, so as to prevent the watch case 9 from being damaged by excessive instantaneous impact force and play a role in protecting the watch case 9. The boss 4 is mounted on the movable seat 6 and is configured to rotate relative to the movable seat 6. The movable seat 6 is provided with an arc-shaped groove 13, and an adjusting rod is provided at the bottom of the boss 4. The diameter of the adjusting rod is adapted to the groove width of the arc-shaped groove 13. The adjusting rod slides along the arc-shaped groove 13. The movable seat 6 has an inner groove 12, and the bottom of the boss 4 is provided with a protrusion 18. The protrusion 18 is located inside the inner groove 12, so that the boss 4 can rotate around the protrusion 18 as the rotation center, thereby adjusting the angle of the boss 4 and thus changing the angle of the watch case 9. This allows for polishing of the inner bevel 10 of the lug 3 from different angles, further improving the comprehensiveness and quality of the polishing. It is worth noting that after adjusting to the preset angle, the boss 4 and the movable seat 6 are locked and fixed with bolts, and then the telescopic component and the movable seat 6 are assembled on the base 5.

[0019] Compared to traditional technologies: The watch case 9 is fitted onto the positioning protrusion 8. One limiting protrusion 1 abuts between two adjacent lugs 3, and the other limiting protrusion 1 abuts against the outer wall of the watch case 9 to restrict the rotation of the watch case 9 relative to the protrusion. The inner bevel 10 of one of the lugs 3 of the watch case 9 fitted onto the positioning protrusion 8 is polished using a polishing device. After the above polishing operation is completed, the watch case 9 is removed and refitted onto the positioning protrusion 8. The watch case 9 is then rotated 90 degrees counterclockwise before being fitted back in. At this time, the clamping position of the lug 3 changes. The above operation of removing and placing the watch case 9 and rotating it 90 degrees before clamping is repeated. Through 4 removals and placements, the inner bevel 10 of all 4 lugs 3 of the watch case 9 is polished. On the one hand, this can effectively improve the polishing efficiency of the inner bevel 10 of the lug 3. On the other hand, it can effectively improve the polishing accuracy of the inner bevel 10 of the lug 3.
